The early and delayed-response genes act as nuclear transcription factors and stimulate the expression of a cascade of other genes. Early response genes such as c-Jun and c-Fos enhance the transcription of delayed-response genes such as E2Fs. E2F transcription factors are required for the expression of various cell cycle genes and are functionally regulated by the retinoblastoma (Rb) protein. Binding of Rb to E2F converts E2F from a transcriptional activator to a repressor of transcription. Phosphorylation of Rb inhibits its repressing function and permits E2F mediated activation of genes required for entry into the S phase. Cdk4-cyclin D, Cdk6 cyclin D, and Cdk2-cyclin E complexes cause phosphorylation of Rb, which remains phosphorylated throughout the S, G, and M phases of the cell cycle. After completion of2 mitosis, a decline of the level of Cdk-cyclins leads to dephosphorylation of Rb by phosphatases and, consequently, an inhibition of E2F in the early G phase. The Cdk4 inhibitor P1446A-05, for example, specifically inhibits Cdk4-mediated G -S phase1 transition, arresting cell cycling and inhibiting cancer cell growth (10). Mitosis is initiated by activation of the cdc gene at the G -M checkpoint2 (11,12). In the presence of abnormally replicated chromosomes, progression past the G -M checkpoint does not occur. Cells exposed to radiation therapy exhibit an S-phase arrest that is accompanied by increased expression of p53. In the presence of p53 mutations, the S-phase arrest that normally follows radiation therapy does not occur (13,14). Apoptosis the regulation and maintenance of normal tissue requires a balance between cell proliferation and programmed cell death, or apoptosis. The reduction in the number of endometrial cells following alterations in steroid hormone levels during the menstrual cycle is, in part, a consequence of programmed cell death (20,21). Programmed cell death, or apoptosis, is an energy-dependent, active process that is initiated by the expression of specific genes. This process is distinct from cell necrosis, although both mechanisms result in a reduction in total cell number. Programmed cell death is triggered by a variety of factors, including intracellular signals and exogenous stimuli such as radiation exposure, chemotherapy, and hormones. Cells undergoing programmed cell death may be identified on the basis of histologic, biochemical, and molecular biologic changes. Histologically, apoptotic cells exhibit cellular condensation and fragmentation of the nucleus. Biochemical correlates of impending programmed cell death include an increase in transglutaminase expression and fluxes in intracellular calcium concentration (23). Historically, neoplastic growth was characterized by uncontrolled cellular proliferation that resulted in a progressive increase in tumor burden. It is recognized that the increase in tumor burden associated with progressive disease reflects an imbalance between cell proliferation and cell death. Cancer cells fail to respond to the normal signals to stop proliferating, and they may fail to recognize the physiologic signals that trigger programmed cell death. Modulation of Cell Growth and Function the normal cell exhibits an orchestrated response to the changing extracellular environment. The three groups of substances that signal these extracellular changes are steroid hormones, growth factors, and cytokines. The capability to respond to these stimuli requires a cell surface recognition system, intracellular signal transduction, and nuclear responses for the expression of specific genes in a coordinated fashion. Among the genes that participate in control of cell growth and function, proto oncogenes and tumor suppressor genes are particularly important. More than 100 proto-oncogene products that contribute to growth regulation have been identified (24) (Table 6. In contrast, tumor suppressor genes exert inhibitory regulatory effects on cellular proliferation (Table 6. Steroid Hormones Steroid hormones play a crucial role in reproductive biology and in general physiology. The action of steroid hormones is mediated via extracellular signals to the nucleus to affect a physiologic response. The structure of both receptors is similar and consists of six domains named A through F from the N to C-terminus, encoded by 8 to 9 exons (26). In addition to the described genomic effects of estrogens, there is growing evidence for nongenomic effects of estrogens on intracellular signal transduction pathways. The cellular and tissue effects of an estrogenic compound appear to reflect a dynamic interplay between the actions of these estrogen receptor isoforms. These observations underscore the complexity of estrogen interactions with both normal and neoplastic tissue. Mutations of hormone receptors and their functional consequences illustrate their important contributions to normal physiology. The clinical sequelae attributed to this mutation include incomplete epiphyseal closure, increased bone turnover, tall stature, and impaired glucose tolerance. The androgen insensitivity syndrome is caused by mutations of the androgen receptor (31). Mutations of the receptors for growth hormone and thyroid-stimulating hormone result in a spectrum of phenotypic alterations. Mutations of hormone receptors may also contribute to the progression of neoplastic disease and resistance to hormone therapy (32,33). Growth Factors Growth factors are polypeptides that are produced by a variety of cell types and exhibit a wide range of overlapping biochemical actions. Growth factors bind to high-affinity cell membrane receptors and trigger complex positive and negative signaling pathways that regulate cell proliferation and differentiation (34). In general, growth factors exert positive or negative effects upon the cell cycle by influencing gene expression related to events that occur at the G -S cell cycle1 boundary (35). Because of their short half-life in the extracellular space, growth factors act over limited distances through autocrine or paracrine mechanisms. The paracrine mechanism of growth control involves the effect of growth factors on another cell in proximity. Growth factors that play an important role in female reproductive physiology are listed in Table 6. The biologic response of a cell to a specific growth factor depends on a variety of factors, including the cell type, the cellular microenvironment, and the cell cycle status. Similar to the ovary, autocrine, paracrine, and endocrine mechanisms of control also occur in endometrial tissue. Intracellular Signal Transduction Growth factors trigger intracellular biochemical signals by binding to cell membrane receptors. In general, these membrane-bound receptors are protein kinases that convert an extracellular signal into an intracellular signal. The interaction between growth factor ligand and its receptor results in receptor dimerization, autophosphorylation, and tyrosine kinase activation. Activated receptors in turn phosphorylate substrates in the cytoplasm and trigger the intracellular signal transduction system (Fig. The intracellular signal transduction system relies on serine threonine kinases, src-related kinases, and G proteins. Many of the proteins that participate in the intracellular signal transduction system are encoded by proto-oncogenes that are divided into subgroups based on their cellular location or enzymatic function (44,45) (Fig. The raf and mos proto-oncogenes encode proteins with serine threonine kinase activity. These kinases integrate signals originating at the cell membrane with those that are forwarded to the nucleus (46,47). This enzyme plays a central role in phosphorylation, which is a general mechanism for activating and deactivating proteins.

The mamillae inverteratae (inverted nipples) which occur from puberty and are bilateral, should also be recognized. The sign of orange-like skin should be further clarified, as well as all eczematous changes of the nipple. The bilateral nipple discharge called galactorrhea is often associated with hyperprolactinemia and is a topic of gynecologic endocrinology. All bloody nipple discharge samples must be examined by imprint cytology and galactography (ductography). Ninety-five percent of findings consist of benign changes (most often intraductal papillomas); bloody nipple discharge is only associated with malignant disease in 5 % of cases. One should also look for bloody discharges from an eczematous nipple associated with Paget carcinoma. Breast palpation may be done in a standing, sitting, or lying position with the arms pressed against the hips, arms at the sides or arms raised. It is very difficult to provide universal instruction for the correct breast examination technique, since different findings are palpable in different positions. Clinicians should always palpate with the entire flattened surface of the stretched finger pads pressed against the chest wall. The entire breast and all of the breast quadrants are palpated in a circular motion. At the end of the examination, the axilla, cervical, supra and infraclavicular lymph nodes are palpated. All palpable tumors and nodes should be carefully characterized based on their size, consistency, shape, movability against the surrounding tissue, particularly skin (plateau phenomenon), and chest wall. Every suspicious palpable finding should be further examined; this is most commonly performed by imaging methods. A significant portion of carcinomas may be identified by clinical examination and history taking. The remaining tumors (clinically occult tumors) cannot be discovered through inspection or palpation and can only be detected by paraclinical examination methods. Imaging techniques for breast lesion diagnosis are described above within interventional methods. Evaluation of the mammography images requires great experience on the part of the examiner. On breast ultrasound, a typical image of breast carcinoma is characterized by an ill-defined hypoechoic lesion with ill-defined borders and posterior acoustic shadowing (Fig. As with mammography, an experienced examiner is required for breast ultrasound interpretation. Every suspicious breast lesion should be examined by some form of percutaneous breast biopsy (see above). Surgical removal of the primary tumor (tumor extirpation, lumpectomy) the final option for defining a breast lesion is its surgical extirpation and definitive histological examination. A semicircular incision is made directly above the tumor or, in cases of periareolar localization, along the lower border of the areola, between the areolar and breast skin. If the lesion leads to skin changes (retraction, fixation), the affected skin region should also be excised (a sickle-shaped incision). Dissection is performed carefully in order to excise the entire tumor / affected tissue. The tissue sample is marked by suture material according to its orientation within the breast, in order to aid the pathologist with tumor orientation. The tumor surface is then stained with ink so the pathologist can identify its margins in paraffin-embedded slides (this is important in cases of malignancy). A needle biopsy, either ultrasound-guided or stereotaxic, in case of pure mammographic manifestation. Afterward, the surgeon makes a semicircular incision just next to the wire and dissects the tissue along the wire up to its end. In cases with microcalcifications, an X-ray image is obtained to verify their presence in the extirpated tissue. Treatment strategies stem from the results of observational studies of different therapeutic regimes and has rapidly changed in recent years. Surgical treatment was previously regarded as a maximum radical procedure, but limited surgery is now the preferred strategy in an effort to maintain the mental and physical integrity of the patient. This is possible thanks to early disease stage detection and new methods of postoperative adjuvant therapy. New prognostic markers for tumor tissue, and grouping patients according to risk, enable individualized treatment planning. Therefore, it is difficult to provide universal recommendations and guidelines for breast cancer treatment. Long-term observations of patients after breast-conserving surgeries showed that, in comparison to mastectomy, breast-saving surgeries do not mean poorer results regarding either recurrences or long-term survival. Nowadays, conservative surgery has become standard treatment in breast cancer patients. Limited breast surgery includes the complete resection of the tumor within healthy tissue, axillary lymph nodes dissection and postoperative irradiation of the breast. Although not the tumor size itself, but rather its relative size in relation to breast size, is important for the surgery type, most candidates for limited surgery are those in stage I of the disease. Larger breasts seem to be appropriate for limited surgery even if larger tumors are present, but they make postoperative irradiation more difficult. Limited surgery may be performed in all cases 83 where an acceptable cosmetic result is expected, in cases with good irradiation tolerance, and if there is no contraindication to the surgery. Contraindications may be divided into: Absolute contraindications: Multicentric carcinoma or extensive multifocality, Diffuse microcalcifications on mammography, Poor cosmetic effect, Postoperative breast irradiation is contraindicated or denied by patient. Some absolute contraindications have become relative as experience has been gained with limited surgery. The sentinel lymph node is the first lymph node or group of lymph nodes draining the area of the primary breast tumor. The concept of sentinel lymph node biopsy consists of preoperative marking of the lymph node (using isosulfan blue dye, radiocoloid or nanoparticles), intraoperative detection (visual detection or detection using a special probe) and a thorough histological 84 examination. This procedure has become dominant in lymph node staging in patients with cT1 tumors with clinically negative axilla (cN0). In these cases, the risk of axilla metastases is low and axillary dissection would unnecessarily burden the patient. Its primary benefits are minimal damage of lymph vessels and a significant reduction in postoperative axillary morbidity. A detailed histological examination of sentinel lymph node micrometastases creates new issues with regard to adjuvant therapy (Fig. Modified radical mastectomy Modified radical mastectomy is the removal of the breast gland with axillary dissection, and with conservation of the major and the minor pectoralis muscle. The breast gland should be removed together with the fascia of the chest muscles and thoroughly dissected from the subcutaneous tissue in order to reduce the risk of recurrences to a minimum. Previously, this procedure was a standard treatment method of breast cancer, and many patients continue to undergo this procedure today in cases of contraindication to breast saving surgery. Rotter-Halsted) this procedure involves the removal of the entire breast gland together with the major and minor pectoralis muscles, and axillary dissection and is performed in cases of muscle infiltration; sometimes, partial resection of the muscle is sufficient. This technique allows for the removal of the breast with preservation of the skin and / or nipple, enabling better cosmetic results of subsequent breast reconstruction. Several studies on skin-sparing mastectomies showed that the incidence of local recurrence is similar to the incidence following simple mastectomies. Contraindications to these approaches include inflammatory breast cancer and skin involvement associated with the tumor.

Chest radiography should be performed to exclude pulmonary metastasis and to evaluate the cardiorespiratory status of the patient. Other routine preoperative studies should include electrocardiography, complete blood and platelet counts, serum chemistries (including renal and liver function tests), and blood type and screen. Other preoperative or staging studies are neither required nor necessary for most patients with endometrial cancer. Studies such as cystoscopy, colonoscopy, intravenous pyelography, and barium enema are not indicated unless dictated by patient symptoms, physical findings, or other laboratory tests (123). This information may be of use in planning the surgical procedure with regard to whether lymph node sampling should be undertaken. With improvements in preoperative and postoperative care, anesthesia administration, and surgical techniques, almost all patients are medically suitable for operative therapy. One study reported an operability rate of 87% in a series of 595 consecutive patients with clinical early-stage endometrial cancer (131). A small percentage of patients will not be candidates for surgical staging because of gross cervical involvement, parametrial spread, invasion of the bladder or rectum, or distant metastasis. Surgical staging was recommended for patients with endometrial cancer since 1988 (134). This recommendation became more controversial after the publication of two large prospective randomized trials that failed to demonstrate improved outcomes for patients who underwent pelvic lymphadenectomy (138,139). The studies share characteristics that could lead to misinterpretation of their results. The percentage of nodal positivity is low in both studies (13% and 9%), suggesting that regardless of differences in exclusion criteria, low-risk cases were included in both studies, thus diluting possible (if any) therapeutic benefit of lymphadenectomy. Another important limitation is that nodal dissection was limited to the pelvis without any recommendation for para-aortic lymphadenectomy. It was demonstrated previously that radiotherapy limited to the pelvis does not improve survival (136). It is not surprising that pelvic lymphadenectomy alone has no therapeutic impact, considering that 67% of patients with nodal involvement have para-aortic lymph node metastases and 16% of patients with documented lymphatic dissemination have isolated para-aortic metastases (140). Neither study used the information derived from lymphadenectomy to target postoperative treatment. Systematic pelvic and para-aortic lymphadenectomy remains one of the most important steps to assess the presence of extrauterine disease and to guide targeted postoperative treatment. The importance of tumor size as a predictor for lymphatic spread was reported by Schink et al. It is possible to identify a group of pa-tients in whom lymphadenectomy is likely to increase the risk of surgical complications without producing any concrete benefits. Tumor diameter, along with myometrial invasion and histologic grade and subtype, can be utilized to determine whether or not lymphadenectomy is appropriate. An observational study reported a significant survival benefit of para-aortic lymphadenectomy in patients at intermediate or high risk of recurrence (based on presence of histologic grade 3 or deep myometrial invasion, or lymphovascular invasion, or evidence of spread outside of the uterine corpus), compared to patients who had hysterectomy with pelvic lymphadenectomy but without para-aortic dissection. From the literature, it seems that the patients who have the potential to benefit from surgical staging are those with risk factors such as histologic grade 3, deep myometrial invasion, or lymphovascular invasion. In summary, surgical staging should (i) identify patients with disseminated disease who are at high risk of recurrence; (ii) target postoperative treatment; (iii) reduce the number of patients potentially requiring postoperative treatment when the provided information is used appropriately (avoiding the risk of morbidity without reasonable benefit); and (iv) possibly eradicate lymphatic disease. In spite of these potential benefits in high-risk patients, prospective randomized data demonstrating a survival advantage or reduction in overall morbidity resulting from a potential reduction of adjuvant treatment still are not available. Other factors, such as tumor size, peritoneal cytology, hormone receptor status, flow cytometric analysis, and oncogene perturbations, are implicated as having prognostic importance. Two reports observed no deaths related to disease in patients with endometrial cancer diagnosed before 50 years of age (145,146). Decreased survival was associated with an increased risk for extrauterine spread (38% vs. Increased risk for recurrence in older patients was related to a higher incidence of grade 3 tumors or unfavorable histologic subtypes; however, age appears to be an independent prognostic variable. Increasing patient age appears to be independently associated with disease recurrence in endometrial cancer. In one study, the mean age at diagnosis of patients who had recurrence or died of disease was 68. None of the patients younger than 50 years of age developed recurrent cancer, compared with 12% of patients aged 50 to 75 years and 33% of patients older than 75 years (149). Histologic Type Nonendometrioid histologic subtypes account for about 10% of endometrial cancers and carry an increased risk for recurrence and distant spread (150,151). In a retrospective review of 388 patients treated at the Mayo Clinic for endometrial cancer, 52 (13%) had an uncommon histologic subtype, including 20 adenosquamous, 14 serous, 11 clear cell, and 7 undifferentiated carcinomas. In contrast to the 92% survival rate among patients with endometrioid tumors, the overall survival for patients with one of these more aggressive subtypes was only 33%. At the time of surgical staging, 62% of the patients with an unfavorable histologic subtype had extrauterine spread of disease (150). Patients with grade 3 tumors were in excess of fivetimes more likely to have a recurrence than were patients with grades 1 and 2 tumors. The 5-year disease-free survival rates for patients with grades 1 and 2 tumors were 92% and 86%, respectively, compared with 64% for patients with grade 3 tumors (149). Another study reported similar results, noting recurrences in 9% of patients with grades 1 and 2 tumors compared with 39% of patients with grade 3 lesions (153). Increasing tumor anaplasia is associated with deep myometrial invasion, cervical extension, lymph node metastasis, and both local recurrence and distant metastasis. Tumor Size Tumor size is a significant prognostic factor for lymph node metastasis and survival in patients with endometrial cancer (142,157). One report determined tumor size in 142 patients with clinical stage I endometrial cancer and found lymph node metastasis in 4% of patients with tumors 2 cm or smaller, in 15% of patients with tumors larger than 2 cm, and in 35% of patients with tumors involving the entire uterine cavity (156). Tumor size better defined an intermediate-risk group for lymph nodes metastasis. Overall, these patients had a 10% risk for lymph node metastasis, but there was no nodal metastasis associated with tumors 2 cm or smaller, compared with 18% when tumors were larger than 2 cm. Five-year survival rates were 98% for patients with tumors 2 cm or smaller, 84% for patients with tumors larger than 2 cm, and 64% for patients with tumors involving the whole uterine cavity (137,157). Patients whose tumors are positive for one or both receptors have longer survival times than patients whose carcinomas lack the corresponding receptors. Even patients with metastasis have an improved prognosis with receptor-positive tumors (161). Progesterone receptor levels appear to be stronger predictors of survival than estrogen receptor levels, and the higher the absolute level of the receptors, the better the prognosis. The proportion of nondiploid tumors increases with stage, lack of tumor differentiation, and depth of myometrial invasion. Myometrial Invasion Because access to the lymphatic system increases as cancer invades into the outer one-half of the myometrium, increasing depth of invasion is associated with increasing likelihood of extrauterine spread and recurrence (153,155,175). The association of depth of myometrial invasion with extrauterine disease and lymph node metastases was reported (175). Of patients without demonstrable myometrial invasion, only 1% had pelvic lymph node metastasis, compared with patients with outer one-third myometrial invasion who had 25% pelvic and 17% aortic lymph node metastases. Deep myometrial invasion (>50% for all stages; fi66% for stage I) is the strongest predictor of hematogenous recurrence (176). In general, patients with noninvasive or superficially invasive tumors have an 80% to 90% 5-year survival rate, whereas those with deeply invasive tumors have a 60% survival rate. Patients with tumors that are less than 5 mm from the serosal surface are at much higher risk for recurrence and death than those with tumors greater than 5 mm from the serosal surface (177,178).

You can also use a pack soaked with may have to tie off the artery despite the consequences of 1mg adrenaline in a bleeding nose (29. Hydrogen Peroxide (6%, 20 vols) is useful not only to clean a wound infected with anaerobic organisms, but will also slow bleeding. When you have transfused >5 units of blood, the citrate in it will lower the calcium concentration in the blood and prevent it clotting. Blood may fail to clot in the presence of liver disease, Vitamin C deficiency, or if the patient has taken excess warfarin or its effect is potentiated by other medicines. In this case, use Vitamin K 10mg orally, but take note it takes 48 hours to be effective! Remember also that aspirin as well as garlic have an anticoagulant effect, and excessive use by patients may cause bleeding problems! Raising the bleeding part will lower the pressure in its veins, and so minimize bleeding. This is valuable if there is bleeding from a limb, or the venous sinuses of the brain (a rare and difficult emergency), when the level of the head in relation to the rest of the body is critically important. For many operations this is essential, You can usually measure the blood lost in a suction bottle. Using a tourniquet in the trauma situation is useful to buy you time whilst you Haemostatic gauze will eventually stop bleeding from the are organizing theatre. Make sure you note how long the oozing cut surface of the liver, or the surface of the brain. Blalock (bulldog) (2) Not to apply pressure when this is indicated, and not to clamps are non-crushing clamps to stop blood spilling from a vessel apply it for long enough, or to apply it diffusely through whilst it is being repaired. Predictably, there was quite a lot of bleeding seen when he Blalock artery clamps (various sizes) released the big aortic clamps. When the professor had sutured in the graft, there was considerable oozing from the suture lines. He simply put in a big pack and asked the assistant to press gently, but firmly, till he returned, and went off to have a cup of tea! When the professor came back 10mins later well refreshed, he re-scrubbed, and removed the pack; the operative field was perfectly dry. When you remove a haemostat fi5mins later, you will probably find that bleeding will have stopped. If you can see a bleeding vessel, you can usually grasp it with these by twisting the haemostat before you remove it, or if the locking forceps, which are one of the great inventions of surgery. Haemostats can be large or small, straight, or curved, so that they rest over the edge of the wound. Each time you tie off a bleeding vessel you leave some crushed tissue and some suture material in the wound. The tips of haemostats, especially small ones, must meet accurately, so good quality instruments are important. Order them in sets of 6 (you can hardly have too many) because they will enable you to make up several sets (4. It is best to cut skin boldly, which produces less bleeding, than tentatively and timidly which produces a sawing-type of action on the vessels. Do not use catgut for larger and more important vessels: it slips off too easily and may be reabsorbed too quickly. This is the method for critically important vessels, A, do not leave too long an end; this will leave unnecessary dead tissue such as those of the renal pedicle. B, to free a vessel buried in tissue, insert Mixter tie it proximal to a branch, and then cut it distal to this. D, tie the artery and insert a transfixion ligature; the needle is going through the vessel and its distal end is If it is a critically important vessel, ask yourself about to be cut off. You may be able and tie a major vessel, such as the external carotid or the to use ligaclips (4. Use linen, cotton thread, or silk; do not divide the vessel after you have tied it, as it may recannulate. Control of the vessels will be safer provide sufficient heat on a small area but without causing if you take one or more bites of the pedicle and tie them muscle spasm and cardiac dysrhythmia, diathermy uses separately. First find the artery In monopolar diathermy, there is a high current density by feeling for pulsation. Push the points of a fine ensured at the point of contact with the active electrode at haemostat into the connective tissue around it and separate the diathermy probe tip but the current is then dissipated in them to open up a plane (3-4B). Gradually develop this a large volume of tissue through a large surface area plane until you can see the artery you are looking for. Usually you will pick up a blood vessel with coagulation in the testicular vessels, especially if you lift dissecting forceps, and touch the forceps with the the scrotum up in your hand. As metal is a good conductor of current, little heat is generated in its passage through the forceps. Do not use diathermy in an amputation for an ischaemic Make sure though that your gloves have no holes, leg (35.

You may not have a special pneumatic tourniquet, so this is probably what you Do not use diathermy on the penis: you may cause will have to use. A tourniquet will prevent blood entering a thrombosis in the corpora unless you use bipolar limb, but it will not remove blood which was already there diathermy. At this point the femoral artery lies close to Then apply a pneumatic tourniquet (or a sphygmo the femur and is easily compressed.

The risk of breast cancer increases with a positive family history and the use of hormone therapy. Breast cancer may be either in situ (ductal carcinoma in situ or lobular carcinoma in situ) or invasive (infiltrating ductal carcinoma, infiltrating lobular carcinoma). The standard screening modalities for detection of breast cancer include yearly mammography and physical examination. Axillary lymph node status and the number of involved nodes are the most important prognostic indicators in primary breast cancer. Sentinel lymph node dissection alone can replace axillary lymph node dissection if the sentinel lymph node is found to be negative on pathology. Adjuvant systemic therapy prolongs survival and is recommended for women with a greater than 10% chance of relapse within 10 years. Breast cancer accounts for approximately one-third of all cancers in women and is second only to lung cancer as the leading cause of cancer deaths among women. Over the past 50 years, the incidence of breast cancer in the United States increased significantly; one in every seven women will develop the disease during her lifetime. Predisposing Factors Less than 1% of breast cancers occur in women younger than 25 years of age. Except for a short plateau between the ages of 45 and 50 years, the incidence increases steadily with age (2). Family History Of women who develop breast cancer, 20% to 30% have a family history of the disease. Although any family history of breast cancer increases the overall relative risk, this risk is not significantly increased if the disease was diagnosed postmenopausally in a first-degree or more distant relative (3). The increased incidence in these women is probably the result of inherited oncogenes. Carriers of these germline mutations have up to a 4% per year risk of developing breast cancer and a lifetime risk that ranges from 35% to 85% (4). These individuals have up to a 65% risk of developing a contralateral breast cancer. Genetic testing is available and should be considered if there is a high likelihood that results will be positive and will be used to influence decisions regarding the clinical management of the care of the patient and her family. Ashkenazi Jewish patients should undergo genetic counseling if any first-degree relative, or two second-degree relatives on the same side have breast or ovarian cancer (6). Genetic testing is increasingly important given the evidence that prophylactic surgery may prevent new cancers from occurring, as well as prolong survival, in some cases. Diet, Obesity, and Alcohol There are marked geographic differences in the incidence of breast cancer that may be related to diet. A meta-analysis demonstrated an association between a healthy diet and lower risk of breast cancer (8). Although a definitive relationship between total alcohol consumption and increased risk of breast cancer has yet to be determined, high wine intake was associated with elevated risk (8,9). Although early menarche was reported among breast cancer patients, early menopause appears to protect against the development of the disease, with artificial menopause from oophorectomy lowering the risk more than early natural menopause (11). There is no clear association between the risk of breast cancer and menstrual irregularity or the duration of menses. Although lactation does not affect the incidence of breast cancer, women who were never pregnant have a higher risk of breast cancer than those who are multiparous. Women who give birth to their first child later in life have a higher incidence of breast cancer than do younger primigravida women (12). A historic well-controlled study from the Centers for Disease Control and Prevention showed that oral contraceptive use does not increase the risk of breast cancer, regardless of duration of use, family history, or coexistence of benign breast disease (13). A pooled analysis from 54 epidemiologic studies showed current users of oral contraceptives had a small but significant increased risk when compared with nonusers. Ten years after discontinuation, the risk of past users declined to that of the normal population (14). This prospective trial, involving 16,000 postmenopausal women randomly assigned to receive estrogen plus progesterone or placebo, revealed an association between hormone therapy use and the development of breast cancer. When invasive breast cancer developed, it was diagnosed at a more advanced stage compared with tumors that developed among placebo users. The risk demonstrated by this study must be considered when postmenopausal hormone therapy is used to treat conditions such as hot flashes and osteoporosis. History of Cancer Women with a history of breast cancer have a 50% risk of developing microscopic cancer and a 20% to 25% risk of developing clinically apparent cancer in the contralateral breast, which occurs at a rate of 1% to 2% per year (16). Lobular carcinoma has a higher incidence of bilaterality than does ductal carcinoma. Diagnosis Breast cancer commonly arises in the upper outer quadrant, where there is proportionally more breast tissue. Masses are often discovered by the patient and less frequently by the physician during routine breast examination. The increasing use of screening mammography has enhanced the ability to detect nonpalpable breast abnormalities. Metastatic breast cancer is found as an axillary mass without obvious malignancy in less the 1% of cases. The standard screening modalities of mammography and physical examination are complementary. Approximately 10% to 50% of cancers detected mammographically are not palpable, whereas physical examination detects 10% to 20% of cancers not seen radiographically (17). The purpose of screening is to detect tumors when they are small (<1 cm) and have the highest potential for surgical cure. Most trials show a 20% to 30% reduction in breast cancer mortality for women age 50 and older who undergo annual screening mammography. Results from the Gothenburg screening trial showed a 45% reduction in mortality for women screened between the ages of 40 and 49 (18). Because of these findings, it is recommended that all women undergo yearly screening mammography starting at age 40, along with clinical breast examination at least every 3 years (19). Screening guidelines recommended by the American College of Radiology and the American Cancer Society are presented in Table 40. Women should be counseled on the benefits and limitation of breast self-examination and should be told to report any changes in their breasts to their health professional right away.

Masses are easier to palpate in older women with fatty breasts than in younger women with dense, nodular breasts. An area of thickening amid normal nodularity may be the only clue to an underlying malignancy. Skin dimpling, nipple retraction, or skin erosion, while obvious, are later-stage disease signs.

Neuromas are sure to develop, but if you do this they will be away from the scar and the finger tip. Flex the index finger and mark out the incision on its knuckle (35-15E,16A), so that the radial flap is larger and extends nearly half-way down the shaft of the proximal phalanx. Deepen the incision dorsally until you can see the extensor tendon, then cut it and turn it distally. Cut the rest of the soft tissues, tie the vessels, shorten the C,D, flaps for amputations through ip joints. F, proximal phalangeal amputation the scar by trimming away the ligaments around the of the middle finger. When you cut flaps through the webs, use a the disadvantage of removing the metacarpal head is that complete web on one side and no web on the other side. D, expose the metacarpal head and remove the distal part of Leave the base of the metacarpal, and suture the deep the finger. Use any convenient occupational therapy, such as rolling Preserve the subcutaneous tissue with the flap, and cut the bandages, to make sure using the fingers starts soon extensor tendons (35-17B). Shorten the flexor tendons as deep in the palm as If a little finger is stiff, and gets in the way, hindering you can. Cut the vessels & nerves distal to the branches of hand function by catching on objects, make a dorsal the palmar skin. Turn the palmar flap medially, and close racquet incision (35-15H); preserve the insertion of the skin without tension. Provided an above-knee amputation stump avoids the this is easier than amputating through the mcp joint. An amputee will also have to learn to balance with the hip Proceed as for the distal phalanx below, but amputate instead of the foot muscles. Join these 2 incisions to make a dorsal flap at the level of the joint, and a palmar flap 1cm distal to the flexor crease (35-15D). Dissect back the fibro-fatty tissue to find the digital vessels and nerves, the extensor expansion, and the flexor tendon in its sheath. Separate the nerves from the vessels, and divide the nerves proximal to the vessels. If <fi of the nail remains, a patient will be troubled later by the irregular hooked remnant, so excise the whole nail bed. If you have to remove some of the pulp, do not make a flap; place a non-stick dressing and allow the wound to heal on its own. If you can preserve the pulp, flex the terminal joint and make a transverse incision across its dorsal surface 6mm distal to the joint (35-15A). Continue the incision as far as the sides of the phalanx, and deepen it down to the bone. Cut the phalanx with bone avoids the condyles of the femur, the longer it is the better. Trim protruding condyles and the anterior part of the phalanx to make a less bulbous stump; then fold the flap and close the wound (35-15B). Rasp away and make (3),cuts little muscle and no bone, so it is quick, there is the end of the bone smooth. Cover the If you have a choice, disarticulating the knee is better than stump with a crepe bandage and then apply a plaster cap. Good prostheses are now available this will relieve pain, and its weight will help to prevent a for disarticulated knees and are easier to use than for flexion contracture developing. Enclose the distal leg as far as the knee in a polythene bag, so as to isolate it If the wound becomes septic, open it up and debride any from the field of operation. Raise the leg so that you If bone protrudes through the stump, re-fashion it can prepare the upper thigh and groin. Put a drape behind making sure the muscles are long enough to cover the it and another one in front. If there is insufficient viable skin on one If the patient has to wait a long time for a prosthesis, side, make the other flap longer rather than amputating pad the stump well, make a cast round it and fit it snugly higher up. This will facilitate walking until Mark incisions for the anterior flap on the medial side of the permanent prosthesis is ready. This may be preferable to a wheel chair, and they will be easier to balance with than Reflect the flaps to the site of section. The centre of gravity end of the anterior flap so as to expose the femoral artery will however be closer to the ground, and two short sticks in its canal under the sartorius muscle. Pull down the femoral make, because they do not have jointed knees, and need nerve, cut it clean and allow it to retract. Ask your assistant to raise the leg while you cut across and Cut a long, broad anterior flap, and a shorter posterior flap bevel the posterior muscles distal to the site of section, in (35-19A). Start the anterior flap on the medial side 1cm proximal to Trim away any excessively bulky muscle masses. Extend it 10cm below this, crossing the Find, clamp, and tie the profunda femoris artery on the leg c. Find the sciatic nerve under proximally to end at a point on to the lateral side of the the hamstring muscles, separate it from its bed without knee opposite to where you started. Do not fashion an anterior flap if it might Reflect the anterior flap upwards with its underlying fascia have an inadequate blood supply. Cut this at its insertion onto medial flaps, the latter 2cm longer than the former, the tibial tuberosity. Now expose and divide the biceps femoris tendon and the iliotibial tract on the lateral aspect of the knee. Find the common peroneal nerve deep to the biceps femoris tendon, cut it clean proximally so it retracts above the level of the amputation. Then reflect the short posterior flap and complete division of the capsule and ligaments of the knee round the whole circumference of the joint below the menisci. Detach the heads of gastrocnemius from the femoral condyles, and remove the lower leg. Draw the patellar tendon posteriorly through the intercondylar notch of the femur, and suture it to the anterior cruciate ligaments under some tension (35-19E). Suture the sartorius and the iliotibial tract to the fascial part of the extensor mechanism. Remove the tourniquet (if present), control bleeding, drain and close the stump with the suture line lying posteriorly (35-19F). Then bring the patellar tendon round so you can fix the undersurface of the patella to the bony stump of the femur. If the blood supply for a long anterior flap is bad, make If a patient has a good prosthesis, he can walk, run, climb medial and lateral flaps. The best length of stump for a prosthesis is 12-18cm E, suture the patellar tendon to the anterior cruciate ligaments. A stump of only 6cm slips too easily out Get your assistant to hold the knee half-flexed. Lift the edge of the posterior flap and divide the medial hamstrings from the tibial tuberosity. Do not amputate below the muscle area of the calf, this exposes the main trunk of the popliteal artery: because the tissue here has a poor blood supply. Behind the artery, find the tibial nerve, draw it gently into Do not amputate below the knee if there is a fixed flexion the wound, and cut it clean (35-19D). Divide the popliteral artery below its superior popliteal pulse is not palpable as the flap will depend on genicular branches which supply the soft tissues of the the profunda femoris artery. Instill an enema before operation to empty the rectum if it It is important that there is absolutely no tension in is full. Suspend the knee over an anaesthetic screen bar for ready If there would be tension at this point, divide the tibia access; if you cannot do this, place an inverted bowl under and fibula higher up; you may find you have to divide the the lower leg. Prepare the skin right up to the groin, in case vessels and nerves again higher up also. If a haematoma forms within the wound, open it up as If you are not certain of the geometry of the flaps, much as necessary and evacuate the haematoma, otherwise cut them too long rather than too short. Start the skin If the wound becomes septic, open it up and debride any incision anteriorly at this point and continue transversely dead tissue; you may need to re-fashion the stump if there round each side of the tibia fi of the way round; is enough length.

Two common prescribing viral skin infections, viral warts and molluscum contagiosum are then considered separately.

This is because the assessed and treated by their local primary care skin disease chapter headings exclude all skin team, particularly when this enables care to be tumours (benign and malignant) and a range of provided in convenient, close to home locations. There is a range of areas where specific research is needed about the effectiveness of services, including traditional well-established models of care. Such boundaries will be particularly important for some patients with skin disease where the distinction between need.

Bronchoalveolar cell carcinoma/adenocarcinoma with lepidic growth is a subset of adenocarcinoma. It occurs more frequently in women and nonsmokers and can present as a single mass, ground-glass opacity, multiple nodules, or an infiltrate. The clinical course can vary from indolent progression to rapid diffuse dissemination. This carcinoma, defined by tumor cells proliferating along the surface of intact alveolar walls without stromal or vascular invasion, is now referred to as adenocarcinoma with lepidic growth. Most (66%) present as central lesions, and cavitation is found in 7% to 10% of cases. Unlike adenocarcinoma, the tumor often remains localized, tending to spread within the pulmonary lobe or to regional lymph nodes rather than systemically; invasion of the chest wall, mediastinum, or other intrathoracic organs is also known to occur. Clinically, large cell carcinomas behave aggressively, with early metastases to the regional nodes in the mediastinum and distant sites such as the brain. Small Cell Lung Carcinoma Small cell carcinoma is associated with neuroendocrine carcinoma because of ultrastructural and immunohistochemical similarities. Small cell carcinomas are believed to represent a spectrum of disease beginning with the well-differentiated, benign/typical carcinoid tumor, moving to the intermediate less differentiated atypical carcinoids or neuroendocrine carcinomas, and ending with the undifferentiated malignant small cell carcinomas. Small cell carcinomas, which tend to grow fast and present with metastatic and regional spread, are usually treated with chemotherapy with or without radiation therapy. Even with seemingly low intrathoracic 327 disease volume, brain metastases may occur; therefore, prophylactic whole brain irradiation is indicated in all cases of small cell lung carcinoma. Carcinoids tend to arise from major bronchi and as such are frequently central tumors that often present with cough or hemoptysis. Immunohistochemically, carcinoids express neuron-specific enolase, chromogranin, and synaptophysin virtually without exception. Neuroendocrine carcinomas or atypical carcinoids occur more peripherally than typical carcinoids and have a more aggressive course, although surgery should still be considered according to clinical stage. Without appropriate immunostaining, they may be classified inadvertently as large cell carcinomas; Ki67 staining is used to estimate the aggressiveness of their behavior, and guide indications for systemic therapy. Diagnosis Signs and symptoms of lung carcinoma depend on the tumor size and location within the thorax. Some tumors may cause cough, hemoptysis, dyspnea, wheezing, and fever (often due to infection from proximal bronchial tumor obstruction). Regional spread of the tumor within the thorax can lead to pleural effusions or chest wall pain. Less common symptoms are superior vena cava syndrome, Pancoast syndrome (shoulder and arm pain, Horner syndrome [miosis, ptosis, anhidrosis], and weakness or atrophy of the hand muscles), and involvement of the recurrent laryngeal nerve, the phrenic nerve, the vagus nerve, or the esophagus. These syndromes are numerous and can affect endocrine, neurologic, skeletal, hematologic, and cutaneous systems. Even with advances in imaging, histologic confirmation is always required to distinguish benign from malignant disease and to determine the histologic type of cancer. Patients with benign lesions should be monitored for interval growth with cross-sectional imaging performed every 6 months for at least 2 years to ensure stability. Staging the primary goal of pretreatment staging is to determine the extent of disease so that prognosis and treatment can be determined. Limited disease is confined to one hemithorax, ipsilateral or contralateral hilar or mediastinal nodes, and ipsilateral supraclavicular lymph nodes. Extensive disease has spread to the contralateral supraclavicular nodes or distant sites such as the contralateral lung, liver, brain, or bone marrow. This edition has further refinement of T-status, as well as additional subgroupings for metastatic disease which are beyond the scope of this chapter. Lymph nodes larger than 1 cm on the short axis have a 30% chance of being benign, whereas lymph nodes smaller than 1 cm still have a 15% chance of containing tumor. National Comprehensive Cancer Network guidelines can be consulted for further recommendations regarding staging and treatment algorithms. Patients with signs and symptoms of significant cardiac disease should undergo further noninvasive testing, including either exercise testing, echocardiography, or nuclear perfusion scans. The pulmonary reserve of patients with lung cancer is commonly diminished as a result of tobacco abuse. In good-performance patients with borderline spirometry criteria, oxygen consumption studies can be obtained that measure both respiratory and cardiac capacity. In conjunction with clinical assessment (6-minute walk and number of flights of stairs climbed), these tests can help identify those patients at high risk of complications during and after surgical resection. Preoperative training with an incentive spirometer, initiation of bronchodilators, weight reduction, good nutrition, and cessation of smoking for at least 2 weeks before surgery can help minimize 332 complications and improve performance on spirometry for patients with marginal pulmonary reserve. A lesser resection (such as segmentectomy or wedge resection) or nonsurgical treatment (such as stereotactic radiation therapy) is indicated if lobectomy cannot be tolerated. If these patients cannot tolerate surgery because of poor medical status, definitive radiation therapy combined with chemotherapy can result in survival rates of 15% to 35%. Patients who still require pneumonectomy after induction therapy may be better served with definitive chemoradiation because of the higher risk of mortality after pneumonectomy. Improved survival is obtained when chemotherapy is combined with radiation therapy, although the complication rate is increased. They are generally not treated surgically since the contralateral mediastinal involvement portends aggressive disease biology. Surgical resection can be considered when the patient shows significant response to therapy and prolonged progression-free interval, although this is the rare exception. Metastatic disease is treated surgically only in the unusual circumstance of a solitary brain or adrenal metastasis with a node negative lung primary. Several reports have documented better local control (in the brain and lung) with surgery in a subset of long-term survivors. The presence of mediastinal nodes, however, contraindicates surgical resection and mandates radiation therapy for the lung primary. In a recent randomized oligometastatic trial, improved progression-free survival rates were demonstrated after locoregional disease control with 334 either surgery or radiation therapy for up to three metastatic sites, compared with survival rates with chemotherapy alone. Patients were randomized after four cycles of chemotherapy to either more systemic treatment or locoregional and oligometastatic disease control with surgery or radiation therapy. The study was stopped prematurely because the primary study outcome was met before completion of the trial. It is associated with higher mortality (4% to 10%) and morbidity than anatomical lobectomy. Advances in bronchoplastic and vascular reconstruction techniques have further obviated the need for pneumonectomy, even when faced with central tumors or those involving the lobar bronchi or pulmonary artery. It is the most common procedure performed for lung cancer, with a perioperative mortality rate of approximately 2%, depending on the risk stratification. From an oncologic standpoint, lobectomy usually achieves complete tumor removal along with the resection of intralobar lymph nodes and the lymphatic pathway; it is the procedure against which all the other procedures and treatment modalities for local lung cancer are measured. Lesser Resections Segmentectomies and nonanatomical wedge resections may be associated with increased local recurrence when compared with lobectomy. The general consensus is that these procedures should be performed predominantly in higher-risk patients with limited pulmonary reserve and tumors <2 cm, who may not tolerate lobectomy. A growing body of literature suggests that minimally invasive techniques are oncologically equivalent to open resection and may be associated with an improved perioperative morbidity profile. There are few absolute contraindications to a video assisted approach, and although the degree of difficulty is increased with chest wall involvement, central tumors, significant hilar adenopathy, or calcified hilar lymph nodes, patients with these conditions can often be safely treated via a minimally invasive technique. Prior thoracotomy is not an absolute contraindication since the degree of adhesions and the ability to mobilize the lung adequately varies among patients. The degree of emphysema, comorbidities, and age are not contraindications, and patients so affected are not treated differently from patients undergoing standard thoracotomy. Extended Operations Improvements in surgery and critical care have allowed certain tumors, previously considered unresectable, to be removed with acceptable morbidity and mortality. Carinal resections, sleeve resections, and extended resections for superior sulcus tumors with hemivertebrectomy and instrumentation of the spine can now be performed in a small subset of patients whose tumors were previously considered surgically unresectable.

Primary breast tumors showed signifcant differences in P-Rex1 or no features of treatment effect (10; 13. None of the other cytologic features were associated with cellularity metastatic tumors expressed higher P-Rex1 levels compared to liver (1. Conclusions:This study corroborates the P-Rex1 expression patterns reported in breast cancer models. Our data also suggests that P-Rex1 is differentially expressed in metastatic tumors based on site and receptor status. The role of P-Rex1 in the development of breast cancer metastases warrants further investigation.
