The prevention and treatment of breast cancer- related lymphedema: A review.

Background: Breast cancer- related lymphedema (BCRL) affects about 3 to 5 million patients worldwide, with about 20,000 per year in the United States. As breast cancer mortality is declining due to improved diagnostics and treatments, the long-term effects of treatment for BCRL need to be addressed. Methods: The American Society of Breast Surgeons Lymphatic Surgery Working Group conducted a large review of the literature in order to develop guidelines on BCRL prevention and treatment. This was a comprehensive but not systematic review of the literature. This was inclusive of recent randomized controlled trials, meta-analyses, and reviews evaluating the prevention and treatment of BCRL. There were 25 randomized clinical trials, 13 systemic reviews and meta-analyses, and 87 observational studies included. Results: The findings of our review are detailed in the paper, with each guideline being analyzed with the most recent data that the group found evidence of to suggest these recommendations. Conclusions: Prevention and treatment of BCRL involve a multidisciplinary team. Early detection, before clinically apparent, is crucial to prevent irreversible lymphedema. Awareness of risk factors and appropriate practice adjustments to reduce the risk aids are crucial to decrease the progression of lymphedema. The treatment can be costly, time- consuming, and not always effective, and therefore, the overall goal should be prevention.

Breast conservation for male breast cancer: Case report of intraoperative radiation.

Male breast cancer (MBC) comprises <1% of all breast cancers in the United States. MBC is typically treated with total mastectomy while the majority of female breast cancer is treated with breast conservation therapy combined with various forms of radiation. One method that has developed over the last two decades is the use of intraoperative radiation therapy (IORT) as a type of accelerated partial breast irradiation to direct the treatment field to the tumor bed. Since overall prognosis and systemic therapy recommendations for MBC are similar to breast cancer in women, we describe the first case of MBC treated with BCS and IORT. Our patient is a 62-year-old male who was found to have a right breast 1.6 cm palpable mass at the 10:00 position 1 cm radially from the nipple. Core biopsy demonstrated invasive ductal carcinoma, moderately differentiated, estrogen and progesterone receptor positive, and Her 2 Negative. The patient had a strong desire for breast conservation, and needed to minimize daily radiation treatments due to his work schedule. After discussion among our multidisciplinary tumor board, we felt this patient to be suitable for BCS and IORT given his age, favorable tumor subtype, size, and clinically early stage breast cancer. A right axillary sentinel lymph node biopsy and central lumpectomy was performed. The INTRABEAM device (Carl Zeiss Meditec, Oberkochen, Germany) was utilized for radiation delivery. The patient had negative margins on his final pathology. The postoperative course was uneventful and at the 6 month follow-up visit there were no issues and he had an excellent cosmetic outcome. BCS and IORT is an option in appropriately selected male patients with favorable subtype early stage breast cancer.

Invasive Ductal Carcinoma within a Benign Phyllodes Tumor.

BACKGROUND Phyllodes tumor (PT) is a rare neoplasm of the breast. Concomitant PT with invasive ductal carcinoma (IDC) is an even rarer occurrence. When ductal carcinoma in situ (DCIS) or IDC are detected within the specimen, the management changes from wide local excision to further staging work-up, including sentinel node biopsy and radiation. CASE REPORT We report the case of a 70-year-old presented with right breast mass whose pathology showed benign PT with concomitant IDC and DCIS. The patient elected for a wide excision of the mass with sentinel lymph node biopsy, which did not show any involvement. The patient was started on appropriate therapy. She is currently doing well. CONCLUSIONS This case highlights the importance of wide local excision for PT as well as prudent histologic examination to rule out other malignant components, as the presence of IDC distinctly changes management.

Beyond Wires and Seeds: Reflector-guided Breast Lesion Localization and Excision.

Purpose To evaluate outcomes of Savi Scout (Cianna Medical, Aliso Viejo, Calif) reflector-guided localization and excision of breast lesions by analyzing reflector placement, localization, and removal, along with target excision and rates of repeat excision (referred to as re-excision). Materials and Methods A single-institution retrospective review of 100 women who underwent breast lesion localization and excision by using the Savi Scout surgical guidance system from June 2015 to May 2016 was performed. By using image guidance 0-8 days before surgery, 123 nonradioactive, infrared-activated, electromagnetic wave reflectors were percutaneously inserted adjacent to or within 111 breast targets. Twenty patients had two or three reflectors placed for bracketing or for localizing multiple lesions, and when ipsilateral, they were placed as close as 2.6 cm apart. Target and reflector were localized intraoperatively by one of two breast surgeons who used a handpiece that emitted infrared light and electromagnetic waves. Radiographs of the specimen and pathologic analysis helped verify target and reflector removal. Target to reflector distance was measured on the mammogram and radiograph of the specimen, and reflector depth was measured on the mammogram. Pathologic analysis was reviewed. Re-excision rates and complications were recorded. By using statistics software, descriptive statistics were generated with 95% confidence intervals (CIs) calculated. Results By using sonographic (40 of 123; 32.5%; 95% CI: 24.9%, 41.2%) or mammographic (83 of 123; 67.5%; 95% CI: 58.8% 75.1%) guidance, 123 (100%; 95% CI: 96.4%, 100%) reflectors were placed. Mean mammographic target to reflector distance was 0.3 cm. All 123 (100%; 95% CI: 96.4%, 100%) targets and reflectors were excised. Pathologic analysis yielded 54 of 110 malignancies (49.1%; 95% CI: 39.9%, 58.3%; average, 1.0 cm; range, 0.1-5 cm), 32 high-risk lesions (29.1%; 95% CI: 21.4%, 38.2%), and 24 benign lesions (21.8%; 95% CI: 115.1%, 30.4%). Four of 54 malignant cases (7.4%; 95% CI: 2.4%, 18.1%) demonstrated margins positive for cancer that required re-excision. Five of 110 radiographs of the specimen (4.5%; 95% CI: 1.7%, 10.4%) demonstrated increased distance between the target and reflector distance of greater than 1.0 cm (range, 1.1-2.6 cm) compared with postprocedure mammogram the day of placement, three of five were associated with hematomas, two of five migrated without identifiable cause. No related postoperative complications were identified. Conclusion Savi Scout is an accurate, reliable method to localize and excise breast lesions with acceptable margin positivity and re-excision rates. Bracketing is possible with reflectors as close as 2.6 cm. Savi Scout overcomes many limitations of other localization methods, which warrants further study. © RSNA, 2017.

Evaluation of the SAVI SCOUT Surgical Guidance System for Localization and Excision of Nonpalpable Breast Lesions: A Feasibility Study.

OBJECTIVE: The purpose of this study is to evaluate the feasibility of the SAVI SCOUT surgical guidance system, which uses a nonradioactive infrared-activated electromagnetic wave reflector, to localize and excise nonpalpable breast lesions. We evaluated the system's use in 15 nonpalpable breast lesions in 13 patients. CONCLUSION: Image-guided placement was successful for 15 of 15 (100%) reflectors. The final pathologic analysis found that lesion excision was successful, including five malignancies with negative margins. No patients required reexcision or experienced complications. SAVI SCOUT is a feasible method for breast lesion localization and excision.

Examination of Duct Physiology in the Human Mammary Gland.

BACKGROUND: The human breast comprise several ductal systems, or lobes, which contain a small amount of fluid containing cells, hormones, proteins and metabolites. The complex physiology of these ducts is likely a contributing factor to the development of breast cancer, especially given that the vast majority of breast cancers begin in a single lobular unit. METHODS: We examined the levels of total protein, progesterone, estradiol, estrone sulfate, dehydroepiandrosterone sulfate, and macrophages in ductal fluid samples obtained from 3 ducts each in 78 women, sampled twice over a 6 month period. Samples were processed for both cytological and molecular analysis. Intraclass correlation coefficients and mixed models were utilized to identify significant data. RESULTS: We found that the levels of these ductal fluid components were generally uncorrelated among ducts within a single breast and over time, suggesting that each lobe within the breast has a distinct physiology. However, we also found that estradiol was more correlated in women who were nulliparous or produced nipple aspirate fluid. CONCLUSIONS: Our results provide evidence that the microenvironment of any given lobular unit is unique to that individual unit, findings that may provide clues about the initiation and development of ductal carcinomas.

Benefits of intraoperative endoscopy: case report and review of 300 sleeves gastrectomies.

BACKGROUND: The laparoscopic sleeve gastrectomy (LSG) is the fastest rising bariatric procedure being performed in the United States. Some surgeons advocate for an intra-operative endoscopy for their leak test, while others utilize air via a form of an oral gastric tube. We present a case demonstrating the benefits of endoscopy intra-operatively as well as discuss our experience of 200 consecutive sleeve gastrectomies. CASE PRESENTATION: The case is a 37 years old female undergoing LSG for treatment for morbid obesity. As is our practice, we routinely perform an intra-operative endoscopy to help ensure a tight seal on the remnant stomach prior to completion of the procedure. During our endoscopy, a blood clot overlying a portion of the esophagus was noted, evacuated and evaluated and found to have a non-bleeding mucosal tear. This was unusual in our experience. There was no leak found on intra-operative endoscopy. After the patient woke up, she starting to have bouts of hematemesis. The decision was made to go back to the OR and evaluate her endoscopically. rather than attempting a laparoscopy based off of our endoscopic findings. Upon take back, we found a mucosal tear in her distal esophagus that now started bleeding, and her staple line was intact. Hemostasis was successfully achieved with two epinephrine injections. The remaining portion of her postoperative course was uncomplicated. DISCUSSION AND CONCLUSIONS: The patient was able to be safely managed with a post-operative EGD. The intra-operative endoscopic findings allowed us to be more confident that this was an esophageal issue rather than a staple line problem, and were able to start with EGD prior to laparoscopy. Additionally, from a visualization perspective, the intra-operative endoscopy allows you to fully visualize the staple line, evaluate for twists or narrowing, and test for leak with confidence. From a residency standpoint, it also increases the confidence of residence to perform endoscopy on intubated patients.

Dr. Susan Love Research Foundation is committed to performing and advancing research that will lead to the discovery of what causes cancer to develop in the human breast. As part of this effort, the Foundation hosted the 8th International Symposium on the Breast in Santa Monica, Calif., Feb. 19 to Feb. 21, 2015. More than 120 forward-thinking clinical researchers, epidemiologists, pathologists, basic scientists, translational investigators, and breast cancer advocates from six countries attended this year's conference, "Using Next Generation Science to Understand the Normal Breast and the Development of Cancer." The highlights from this year's symposium are summarized in this report.

Factors influencing 30-day emergency visits and readmissions after sleeve gastrectomy: results from a community bariatric center.

INTRODUCTION: Bariatric surgery has proven safe and effective for long-term weight loss in morbidly obese patients. Readmissions within 30 days of discharge have become an important metric for quality of care. Sleeve gastrectomy is a common bariatric procedure, but data regarding early readmission is sparse. The purpose of this study is to determine what, if any, demographic or technical factors influence returns to the hospital or readmission following sleeve gastrectomy. METHODS: All laparoscopic sleeve gastrectomies (n = 200) performed at a single community hospital from February 2009 to November 2012 were retrospectively reviewed. Demographic, technical, length of stay, return to Emergency Department (ED) and readmission data were gathered for each patient. The data were analyzed to determine what factors were related to early return to the Emergency Department or readmission. RESULTS: Demographics were similar to other studies, with a male to female ratio of 1:4. Patients returning to the ED or readmitted within 30 days were statistically younger than those not returning. None of the other demographic, social, technical, or comorbid conditions considered were associated with a statistically significant risk of readmission or return to the ED within 30 days. CONCLUSION: Although the only statistically significant difference among the groups studied was age, trends toward significance exist in minority ethnicity and comorbid asthma. These factors have been associated with increased complications in other types of surgery. Larger, multi-institutional studies are needed to further evaluate these and other risk factors for readmission following bariatric surgery.

Outcome analysis of single incision vs traditional multiport sleeve gastrectomy: a matched cohort study.

BACKGROUND: Single incision laparoscopy remains controversial due to technical challenges which may cause suboptimal outcomes. This study aims to evaluate the feasibility and equivalency of the single incision sleeve gastrectomy (SISG) when compared to the traditional multiport sleeve gastrectomy (MPSG) approach in a matched cohort evaluating technical aspects and postoperative results. METHODS: This is a retrospective analysis of prospectively collected data in a consecutive cohort of 113 SG (MPSG = 77, SISG = 36). The 36 patients who underwent SISG were included as the case group. Thirty-six MPSG patients were included in the control group, in 1:1 ratio with cases after matching for BMI, age, race, gender, and additional demographic data. Operative time (OT) in minutes and length of stay (LOS) in days was measured and excess weight loss (EWL) at 6 months and 1 year was collected and evaluated. RESULTS: Mean BMI was equivalent (SISG 43.06, MPSG 43.72, p = 0.36). Mean OT for the SISG was 116.78 and 118.25 for the MPSG (p = 0.84), and mean LOS was 1.80 for the SISG and 1.75 for the MSPG (p = 0.75). EWL at 6 months was 58.4 % for the SISG and 58.5 % for the MPSG (p = 0.98) and 72.3 and 74.1 % (p = 0.77) for 1 year, respectively. There were no leaks in either group. There was one reoperation for postoperative bleeding in the MPSG group. CONCLUSIONS: Sleeve gastrectomy can be performed safely using single incision techniques with equivalent outcomes for weight loss.

How to use molecular testing results to guide surgery: a surgeon's perspective.

PURPOSE OF REVIEW: Multiple genetic mutations have been found to be associated with thyroid cancer, and molecular testing of thyroid nodule fine-needle aspiration (FNA) specimens has been proposed as an adjunct to the cytologic diagnosis. The purpose of this review is to examine how molecular testing of FNAs could be used to guide surgical decision-making. RECENT FINDINGS: B-type RAF kinase mutations in papillary thyroid cancer have been found to be associated with extrathyroidal extension, lymph node metastases, and advanced stage in two meta-analyses that are based largely on retrospective data. Testing for a panel of gene mutations has been found to have high specificity and positive predictive value, whereas microarray testing using a commercially available gene-expression classifier has been found to have high sensitivity and negative predictive value for the diagnosis of malignancy in cytologically indeterminate FNAs. Although there is no consensus regarding the use of such tests, they have already started to change clinical practice. SUMMARY: Molecular testing of FNA specimens may help to avoid diagnostic thyroidectomy or may help in deciding the extent of surgery in a patient with an indeterminate FNA biopsy. The use of these tests is currently undergoing review by a task force within the American Thyroid Association.

Efficacy and safety of hylan G-F 20 for symptomatic glenohumeral osteoarthritis: a prospective, pilot study.

OBJECTIVE: To determine the safety and efficacy of 2 intra-articular, fluoroscopically guided hylan G-F 20 injections for painful glenohumeral osteoarthritis. DESIGN: This study was a prospective open-label pilot investigation with both U.S. Food and Drug Administration and institutional review board approval. SETTING: Private, outpatient practice within a tertiary care, university medical school. PARTICIPANTS: Thirty-six subjects with moderate to severe glenohumeral osteoarthritis, with pain (visual analog scale [VAS] 40 mm or greater) despite following a 3-month standard, nonsurgical treatment program. INTERVENTIONS: Two injections of 2 mL hylan G-F 20, under fluoroscopic guidance confirmed by arthrography, 2 weeks apart. No new treatments were allowed during the course of the study. Analgesics were discontinued 24 hours before visits. MAIN OUTCOME MEASUREMENTS: Data collected were radiographs; rotator cuff integrity as determined with magnetic resonance imaging; VAS for pain at rest, at night, and with activity; and shoulder-related quality of life (Western Ontario Rotator Cuff Index [WORC]). Subjects were re-evaluated after each injection and at 6 weeks, 3 months, and 6 months. Changes from baseline for VAS and WORC were recorded in Excel and analyzed using SPSS. Intent-to-treat analysis was performed. The type and severity of adverse events were recorded. RESULTS: Mean VAS at baseline was 63 mm (SD 14.5). Clinically (>or=20% improvement) and statistically significant improvements (P < .001) in VAS pain were seen at 6 weeks, 3 months, and 6 months. Mean improvement in WORC at 6 months was 16.5 (P < .01), with most gains in "lifestyle" and "emotion" questions. Age, gender, body mass index, and rotator cuff pathology did not correlate with response. Three subjects described heightened pain for a few days after injections. Three subjects reported greater pain at 6 months and were unsatisfied. Four experienced no effect of treatment. There were no inflammatory reactions. CONCLUSION: Two hylan G-F 20 injections improved pain and function, and should be considered as part of a multimodal shoulder osteoarthritis treatment program.
