Neoadjuvant Therapy (Systemic or Hormonal) Another trend in breast cancer treatment is targeted individualized therapy depending on various tumor characteristics spasms multiple sclerosis purchase 500 mg robaxin mastercard. This had led to an increase in delivering preoperative systemic chemotherapy or hormonal therapy to better document the treatment effect of a specific regimen prior to surgery spasms right upper abdomen buy 500mg robaxin mastercard. Performing surgery after neoadjuvant therapy will contribute significant information on tumor responsiveness of a particular regimen and Chapter 14 Partial Mastectomy 211 help guide future systemic treatment muscle relaxant benzodiazepines order 500mg robaxin overnight delivery. In addition spasms after surgery generic 500 mg robaxin with mastercard, some patients will become candidates for breast conservation if treated with systemic therapy prior to surgery. Studies have shown that it is safe to offer upfront therapy (neoadjuvant chemo or hormonal treatment, also referred to as primary systemic chemotherapy or hormonal therapy) with only a minority of tumors progressing on therapy during such an approach. It is important for surgeons to clinically follow patients during neoadjuvant therapy to assess response to treatment and ensure that unresponsive tumors do not require a change in therapeutic intervention that may include a more immediate surgical procedure. Preoperative hormonal therapy is used for elderly patients and may take the place of surgery in a patient with multiple comorbid diseases who may be at high risk for surgery. For this elderly group, each case is decided upon on an individual basis and if the patient responds well to this approach, consideration for partial mastectomy in an outpatient setting under intravenous sedation in the operating room can take place at the point the tumor is no longer responding to the treatment regimen. Role of Oncoplastic Surgical Techniques Depending on the size of the partial mastectomy resection, some patients may benefit from oncoplastic surgical techniques in repairing the defect. This is an emerging field that offers patients an alternative to mastectomy, especially for very large defects in patients with generous breast tissue who may benefit from opposite breast reduction surgery. Factors involved in the surgical decision making for oncoplastic procedures after the performance of partial mastectomy include the following: Timing of reconstruction in relation to radiation therapy: It is ideal to consider oncoplastic surgery prior to partial mastectomy and radiation. Patients who present after completion of surgery and radiation are a challenge because if the defect is large, they may require transfer of significant amount of autologous tissue. In this setting, the remaining breast tissue has been exposed to radiation and wound healing may be Figure 14. Often these patients have chosen breast conservation therapy because of a desire to have less versus more surgery. Sometimes, completion mastectomy and immediate reconstruction are the best options for significant defects. Status of tumor margins: Oncoplastic techniques can be performed immediately after the partial mastectomy or delayed a week or two for final margin status determination (but before radiation is administered). If multicentric disease is suspected, the latter approach, with delay to confirm final margins, is advantageous. However, if disease appears localized, a unified procedure can be recommended, thus avoiding a second procedure in the operating room. Extent of breast skin and tissue resection: this will be determined by the size of the tumor and proximity to the anterior skin margin. If reduction procedures are planned, the incisions for the partial mastectomy portion of the procedure can be in the same location of the reduction incisions. Careful planning between the surgical oncologist and the plastic surgery team is necessary for this approach. At the time of surgery, specimen mammography may be necessary to confirm that the entire lesion is resected with a visually acceptable margin. Breast size: Patients with pendulous breasts may benefit from oncoplastic techniques even if the lesion for resection is small. Radiation to large breasts can be compromised and uneven dosages may occur in this group of patients. It is desirable to perform the partial mastectomy and bilateral reduction prior to radiation therapy as opposed to performing reduction surgery after the patient has completed all therapy. Ultimate cosmetic outcome: An assessment needs to be made preoperatively if the patient would benefit from completion mastectomy versus wide partial mastectomy and reduction of the involved breast. If a patient does not meet criteria for postmastectomy radiation, the advantage to simple mastectomy and reconstruction may be to avoid radiation. Genetic testing may delay surgery; however, if a patient is a candidate for neoadjuvant therapy, that treatment can proceed while the patient is referred for genetic counseling and possible testing. Patients will often have predetermined desires regarding breast conservation surgery versus mastectomy. Data regarding the safety of breast conservation should be discussed with the patient. Even after these discussions, a group of patients will desire mastectomy and furthermore even request bilateral mastectomies (contralateral prophylactic mastectomy) with or without immediate reconstruction. While there is no survival advantage to this approach, an increasing trend of bilateral mastectomies in the setting of unilateral cancer has been identified. Prevention of Acute Complications There is ongoing debate about the role of prophylactic antibiotics for breast surgery. Several studies report the advantage of prophylactic antibiotics given as a one time dose 30 minutes prior to surgery, yet others have shown no benefit. High-risk patients, those who are obese, the elderly, and diabetic may be those who benefit from prophylactic antibiotics to a greater extent. Foreign body placement, wire localizations and clips for marking biopsy sites, may add to risk of infection and one may consider use of prophylactic antibiotics in these settings as well. Prevention of bleeding and hematoma formation can take place by obtaining an accurate preoperative history of use of blood thinners such as daily aspirin or antiinflammatory medications. If possible, these medications should be stopped 10 days to 2 weeks prior to surgery. Surgery should be delayed about 4 weeks after the last infusion of bevacizumab (Avastin) because of the potential of bleeding and dehiscence. Other agents that contribute to bleeding in breast patients are Vitamin E, ginseng, ginko biloba, and garlic. Some surgeons prefer deep closure to decrease risk of hematoma formation, but this may compromise cosmetic appearance.
Surgeons often ask radiologists to leave the needle in place over the wire spasms around heart purchase 500 mg robaxin, as the needle is more easily palpable during surgery and facilitates accurate resection spasms under belly button robaxin 500 mg mastercard. Radiologists and/or staff will likely secure the wire in place with various methods muscle relaxant brand names generic 500mg robaxin free shipping, using a dressing muscle relaxant eperisone hydrochloride cheap robaxin 500 mg fast delivery, Steri-Strips, or other means to secure the wire, and avoid potential movement or dislodgement. If a lesion is close to the skin and especially if retraction is present, a small portion of skin overlying the retraction may need to be excised. Skin removal creates a mastopexy effect and can contribute to slight asymmetry when compared with the contralateral breast. Excision of extensive skin should be avoided unless coupled with oncoplastic surgical techniques for a closure that addresses the contralateral breast as well. The surgeon should remove the outer dressing or Steri-Strips securing the wire before the breast is prepped with surgical soap. The entry site of the wire in the breast should not necessarily dictate the incision on the breast. The incision on the breast is dictated by the location of the breast lesion and cosmetic considerations. Many if not most breast lesions can be accessed through circumareolar incisions. Technical Considerations Often, the wire enters the skin of the breast at some distance from the lesion and may not be near the areolar border. The surgeon may mark the anticipated skin incision and make an incision remote from the wire. A skin flap is then carefully created in the somewhat avascular fatty plane between the skin and breast tissue, using small skin hooks, until the wire is visualized in the breast. Using wire cutters, the wire is then cut several millimeters above the skin at its entry point, and the external portion is removed from the operative field. The skin flap is carefully carried beyond the wire so that the entire circumference of breast tissue can be easily visualized where the wire enters the breast tissue. The wire is gently grasped at its proximal end with a clamp, such as an Allis clamp, to include some of the surrounding breast tissue (Fig 7. Chapter 7 Needle Localization Biopsy of Nonpalpable Breast Lesions 119 A B Figure 7. Using wire cutters, the wire is cut several millimeters above the skin at its entry point, and the external portion is removed from the operative field. If the tissue is removed in a "triangular" fashion with the tissue toward the wire tip being the point of the triangle, the lesion may be missed or inadequately excised. Therefore, a trough is made around the wire at the superior, medial, inferior, and lateral sides of the wire by using either the scalpel or electrocautery. Each trough is carefully carried down to below the wire tip or further if the lesion is distal to the wire tip. The specimen should ideally be labeled with sutures or other suitable markers while it is in vivo to ensure accurate orientation. At least two sutures or markers should be used for proper orientation and margin assessment. The depth of the trough is determined by the depth of the needle, and the trough around the needle generally extends beyond the tip of the wire to allow adequate excision of the tissue at the wire tip, where the lesion is generally located. The specimen is then divided at its deep or posterior margin and removed from the operative field. The surgeon should aim to achieve a 1-cm margin around the lesion and should palpate the tissue before removing the specimen from the operative field (Fig 7. The specimen is carefully placed on a grid for imaging to confirm adequate excision of the lesion. Hemostasis is of course meticulously achieved, and the wound can be infiltrated with local anesthetic. If the lesion excised is a known or suspected cancer, the surgeon may place several hemoclips in the surgical bed to mark the area for eventual radiotherapy. If the lesion is not accessible via a circumareolar incision, either due to the location of the lesion or due to the size of the areola compared with the breast size, then appropriate incisions should be made to allow access to the lesion with a satisfactory cosmetic result. The procedure is similar, in that a flap is created on either side of the wire, and a similar cylindrical specimen is removed. Lesions in the lower pole of the breast may be approached through an inframammary or a radial incision. If the lesion is a suspected cancer, the surgeon should be mindful of the possible decision for mastectomy. The incision should be placed in such a manner to allow eventual skin-sparing mastectomy. Incisions along the Langer lines of the breast may be problematic if further surgery is indicated. Radial incisions are generally preferred, as these can then be incorporated in the mastectomy incision if needed. Some of these problems are of a pragmatic nature, whereas others are more technically challenging. Anticipation of potential problems or "pitfalls" will assist the surgeon in the care of patients with nonpalpable lesions. Pitfall: Missed lesions can be the result of a less than optimally placed needle or wire.

This approach has evolved from the initial concept of "primary" versus "secondary" prevention muscle relaxant remedies buy discount robaxin 500mg line, as the dichotomous classification spasms 14 year old beagle order 500 mg robaxin otc, although simple muscle relaxant quiz cheap 500 mg robaxin visa, may not be the best approach when there is a continuum of risk spasms stomach buy robaxin 500 mg without prescription. The approach taken by the American Diabetes Association has been to identify those with "prediabetes," as alluded to earlier. In contrast, for individuals who were in the lower five deciles of risk, the observed rates for developing diabetes over 9 years ranged from 1 to 9%. Quantitative risk assessment to identify individuals at the highest risk for development of diabetes would also optimize resource allocation to identify which individuals may benefit the most from more intensive and more expensive lifestyle modification programs and/or pharmacotherapy. This approach has been used extensively to determine which patients merit drug therapy for hyperlipidemia and is the basis of reimbursement of drug therapy for hyperlipidemia in many countries. Extending routine systematic assessment from cardiovascular risk to cardiometabolic risk-i. An American Heart Association/National Heart, Lung, and Blood Institute Scientific Statement. American Heart Association; National Heart, Lung, and Blood Institute, Cardiol Rev. Clinical implications of obesity with specific focus on cardiovascular disease: a statement for professionals from the American Heart Association Council on Nutrition, Physical Activity, and Metabolism: endorsed by the American College of Cardiology Foundation. National Heart, Lung, and Blood Institute; American College of Cardiology Foundation; American Heart Association. These approaches along with dramatic improvements in treatment of acute coronary syndromes, revascularization procedures for coronary artery disease, and reduced smoking have led to marked improvements in the age-adjusted incidence of cardiovascular events. Erectile dysfunction is certainly an extremely common phenomenon and is even more prevalent in patients with cardiovascular disease and risk factors. The risk of adverse cardiovascular events in higher risk populations is even more profound. In diabetic patients with erectile dysfunction and asymptomatic coronary artery disease, the hazard ratio for incidence of major adverse cardiovascular events is 2. This is particularly remarkable, considering the absence of angina in this population. Erectile dysfunction may be a precursor to the diagnosis of underlying and menacing, but largely unrecognized, cardiovascular disease and cardiovascular risk. Erectile dysfunction is a harbinger of cardiovascular disease and cardiovascular events. Presentation of new-incident erectile dysfunction should prompt an evaluation for potentially modifiable cardiovascular risk factors and disease regardless of the presence of absence of other cardiac symptoms. The Second Princeton Consensus recommends measurement of blood pressure, blood glucose, lipids, and screening for vascular disease in all men with erectile dysfunction that lacks an obvious cause (such as trauma). This is useful information, as these diseases often lack obvious clinical symptoms. Patients with erectile dysfunction are also more likely to have metabolic syndrome, lead sedentary lifestyles, or have a history of smoking. This is manifest by an increased likelihood of having a positive stress test, significant coronary artery calcification, or angiographically proven coronary artery disease. This subsequently results in relaxation of arterial and trabecular smooth muscle, allowing for increased blood flow into the penile sinusoids. The filling of the sinusoids causes compression of the venous plexuses that drain the penis, thereby greatly reducing outflow. This combines to increase the intracavernous pressure within the penis, leading to tumescence. Hypertension, dyslipidemia, obesity, and tobacco use have all been shown to be associated with endothelial dysfunction by various inflammatory and humoral-hormonal processes. Endothelial dysfunction is a key contributor to the development and progression of atherosclerosis itself and is correlated with myocardial ischemia and cardiovascular events. Endothelial dysfunction is a mechanism of systemic vascular disease- and penile vasculature is not spared. Low-risk patients are generally at insignificant risk for cardiac complications from sexual activity. However, further evaluation, including noninvasive testing, may be recommended so that the risk of sexual activity may be more judiciously investigated (Table 25-1). However, patients at low risk may safely engage in sexual activity and may be treated for erectile dysfunction. First-line therapies should be considered on an individual basis, and it is recommended that patients be reassessed every 6-12 months for change in clinical status. A full history and physical as well as screening laboratory tests provide data necessary for proper evaluation of risk. All cardiovascular risk factors should be assessed and appropriately managed during this initial evaluation. While there is insufficient data to encompass all cardiac diseases, most patients can be stratified into one of three major graded categories of cardiac risk defined by the Second Princeton Consensus: lowrisk, intermediate risk, and high risk (Tables 25-1 to 25-3). Proper management of these diseases may allow patients to be restratified into the low risk group. High risk patients have sufficiently severe cardiac conditions and are at significant risk of cardiac symptoms and complications from any physical activity, including sexual activity. Age Hypertension Diabetes mellitus Obesity Cigarette smoking Dyslipidemia Sedentary lifestyle Male, postmenopausal female* Physiology of Sexual Activity the physiologic effect of sexual arousal and sexual activity is somewhat variable. However, sexual activity is associated with sympathetic activation, which may elevate blood pressure and may induce arrhythmias ranging from premature complexes to ventricular tachyarrhythmias. The physiologic response may be greater than with exercises of similar metabolic demand as sexual arousal may also augment the sympathetic response of sexual activity. While cardiac complications of sexual activity are rare, it is critical to assess cardiac risk prior to treating erectile dysfunction due to the consequences of sexual activity on cardiac physiology. Cardiologic evaluation, testing, and management should be prioritized before recommending resumption of any sexual activity.
Similarly muscle relaxants quizlet purchase discount robaxin on line, within the incision utilized for a modified radical mastectomy done without skin-sparing muscle relaxant half-life generic 500mg robaxin, the full axillary lymph node dissection may be performed without additional incision muscle relaxant ibuprofen buy robaxin with american express. Alternately muscle relaxant 751 cheap robaxin 500 mg without a prescription, a skin-sparing incision does not always allow for the dissection, and a separate counter incision is made in the axilla or as an extension of a prior sentinel lymph node biopsy incision. The incision made would be the same as one would use in conjunction with lumpectomy, extending from the anterior to the posterior axillary fold, preferably below the area bearing hair, in a preexisting skin fold. When a separate incision is necessary, skin flaps need to be raised superiorly to the axillary fold and inferiorly to approximately the lateral extent of the inframammary fold. To open up the axilla easily during the operation, a rigid ether screen is first attached to the table before the patient is prepped and draped. Should higher axillary access be needed, the pectoralis muscles can be retracted more medially by suspending the hand and arm from the crossbar as shown. The wrist is then wrapped with a towel and the towel folded over the drape and crossbar. A wide clamp, such as the mandibular clamp, is placed over the towel, drape, and crossbar, thereby suspending the arm over the upper chest and face. More easily, dissection along the lateral pectoral major border is performed, isolating this edge. The pectoralis major muscle is then retracted medially, exposing the pectoralis minor muscle. At this point, an interpectoral dissection can be performed, especially if any Rotter nodes are suspected to be enlarged. At the medial surface of the pectoralis minor muscle, the advential tissues is carefully divided by using the electrocautery, taking care to preserve the muscle and the medial pectoral neurovascular bundle, which innervates both the pectoralis major and minor muscles, located near the superolateral aspect. The advential tissues are placed on traction laterally, utilizing a sponge, and the advential tissues carefully teased off the surface, maintaining these tissues in continuity with the axillary contents. The pectoralis minor muscle is then retracted medially as well, allowing for the division of the more posterior layers of the clavipectoral (or axillary) fascia. These Chapter 12 Axillary Lymph Node Dissection 189 Pectoralis major Underside of resected breast, reflected off lateral edge of pectoralis major Skin ellipse of breast incision A Figure 12. In a modified radical mastectomy (simple mastectomy axillary lymph node dissection), an elliptical incision is utilized. The breast can be oriented with sutures or other device and excised separate from the axillary contents, or the breast can be classically maintained in continuity with the axillary contents. This will require transfer of the breast from resting on the lateral aspect of the operating table at times to resting on the chest wall. The attention is then turned to defining the lateral border of the latissimus dorsi muscle. With palpation, this border can be located and combined blunt dissection with electrocautery used to define this edge. Superiorly, care is taken not to travel beyond the transition to the tendon of insertion as this brings the surgeon precariously close to the axillary vein. Within this dissection, one is likely to encounter branches of the intercostobrachial nerve, usually within 2 cm of the lower aspect of the axillary vein. It is typically difficult to spare branches that lie farther from the vein than a 0. In the patient with a larger breast, the breast is first removed through the skin envelop prior to axillary lymph node dissection. The opening for the skin envelope may have sufficient loss of volume such that the opening can be placed over the axilla, allowing for a dissection without addition incision. Should the patient having a skin-sparing incision have a small breast envelope, a counter incision within the axilla can be planned, generally without causing ischemia to the flap. The same incision can also be utilized if axillary lymph node dissection is performed in conjunction with a partial mastectomy or in another setting. The incision preferably is placed under the area bearing hair, following skin line folds or a preexisting skin fold, from the anterior axillary fold (pectoralis major muscle lateral edge) to the posterior axillary fold (latissimus dorsi muscle lateral edge). Pectoralis major muscle Pectoralis minor muscle Lateral pectoral nerve Medial pectoral nerve Axillary vein A Anterolateral fibers of the latissimus dorsi muscle (passes under axillary vein) Thoracoepigastric vein empties into lateral thoracic vein (Lateral thoracic vein can sometimes be separate in some patients) Thoracodorsal vein Pectoralis major muscle Pectoralis minor muscle Serratus anterior muscle Axillary vein B Thoracodorsal vein and artery Posterior Long thoracic Thoracodorsal circumflex Subscapular nerve nerve vein vein Figure 12. With retraction of the pectoralis major muscle medially, the anterior surface of the pectoralis minor muscle is visualized through adventitial tissue. The adventitia is incised along the medial anterior surface of the pectoralis minor muscle. With this adventitia placed on tension laterally, it can be slowly peeled off the anterior surface of the pectoralis minor muscle with the assistance of the electrocautery, keeping the adventitia and any Rotter nodes in continuity with the axillary contents. Once the lateral borders of the pectoralis major muscle and latissimus dorsi muscles have been exposed up to the level of the axillary vein, tension on the fat pad inferiorly helps to expose the inferior venous tributaries. If one suspects that the axillary vein is near but cannot visualize its color or shape, certainly a pause in the dissection at that time would be prudent. One can reassess the approximate expected level of the axillary vein near the level of the medial arm, should the arm be out at a right angle to the body. Be aware that the axillary vein (10) can often be found to bifurcate, and rarely trifurcate, within the axillary space. Hence, transverse venous structures high in the axilla, even if they are not as large as expected for an axillary vein, should not be ligated as they may be part of a divided system. With these two borders defined-anterior and posterior-the axillary contents are placed on gentle traction inferiorly, allowing one to catch a glimpse of the axillary vein between two fat lobules or planes that separate with the traction, if it has not yet already been identified.
