A 4-Year Institutional Experience of Immediate Lymphatic Reconstruction.

BACKGROUND: Up to one in three patients may go on to develop breast cancer-related lymphedema (BCRL) after treatment. Immediate lymphatic reconstruction (ILR) has been shown in early studies to reduce the risk of BCRL, but long-term outcomes are limited because of its recent introduction and institutions' differing eligibility requirements. This study evaluated the incidence of BCRL in a cohort that underwent ILR over the long term. METHODS: A retrospective review of all patients referred for ILR at the authors' institution from September of 2016 through September of 2020 was performed. Patients with preoperative measurements, a minimum of 6 months of follow-up data, and at least one completed lymphovenous bypass were identified. Medical records were reviewed for demographics, cancer treatment data, intraoperative management, and lymphedema incidence. RESULTS: A total of 186 patients with unilateral node-positive breast cancer underwent axillary nodal surgery and an attempt at ILR over the study period. Ninety patients underwent successful ILR and met all eligibility criteria, with a mean patient age of 54 ± 12.1 years and median body mass index of 26.6 kg/m 2 [interquartile range (IQR), 24.0 to 30.7 kg/m 2 ]. The median number of lymph nodes removed was 14 (IQR, eight to 19). Median follow-up was 17 months (range, 6 to 49 months). Eighty-seven percent of patients underwent adjuvant radiotherapy, and among them, 97% received regional lymph node irradiation. The overall rate of lymphedema was 9% at the end of the study period. CONCLUSIONS: With the use of strict follow-up guidelines over the long term, the authors' findings support that ILR at the time of axillary lymph node dissection is an effective procedure that reduces the risk of BCRL in a high-risk patient population. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Variable Anatomy of the Lateral Upper Arm Lymphatic Channel: An Anatomical Risk Factor for Breast Cancer-Related Lymphedema.

BACKGROUND: The lateral upper arm channel is an accessory lymphatic pathway that drains the upper extremity by means of the deltopectoral groove and supraclavicular nodes, thereby bypassing the axilla. Its variable connectivity to the forearm has not been studied in vivo. METHODS: Indocyanine green (ICG) lymphography was performed preoperatively to map the superficial and functional arm lymphatics in breast cancer patients without clinical or objective evidence of lymphedema. A retrospective review was performed to extract demographic, ICG imaging, and surgical data. RESULTS: Sixty patients underwent ICG lymphography before axillary lymph node dissection between June of 2019 and October of 2020. In 59%, the lateral upper arm lymphatic channel was contiguous with the forearm (long bundle). In 38%, the lateral upper arm lymphatic channel was present but not contiguous with the forearm (short bundle). In 3%, the lateral upper arm pathway was entirely absent. Seven patients developed at least one sign of lymphedema during postoperative surveillance, of which 71% demonstrated the short bundle variant. CONCLUSION: Although the lateral upper arm pathway is most often present, its connections to the forearm are frequently absent (short bundle), which, in this pilot report, appears to represent a potential risk factor for the development of lymphedema. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, V.

Innovation in Breast Surgery: Practical and Ethical Considerations.

The adoption of innovation is essential to the evolution of patient care. Breast surgical oncology advances through incorporating new techniques, devices, and procedures. Historical changes in practice standards from radical to modified radical mastectomy or axillary node dissection to sentinel node biopsy reduced morbidity without sacrifice in oncologic outcome. Contemporary oncoplastic techniques afford broader consideration for breast conservation and the potential for improved cosmetic outcomes. At present, many breast surgeons face the decision of which wireless device to use for localization of nonpalpable lesions. Consideration for future changes, such as robotic mastectomy, are on the horizon. No guideline exists to assist breast surgeons in the adoption of innovation into practice. The Ethics Committee of the American Society of Breast Surgeons acknowledges that breast surgeons confront many questions associated with onboarding innovation. This paper aims to provide a framework for asking relevant questions along with the ethical principles to consider when integrating an innovation into practice.

Evaluating the Impact of Immediate Lymphatic Reconstruction for the Surgical Prevention of Lymphedema.

BACKGROUND: Breast cancer-related lymphedema affects one in five patients. Its risk is increased by axillary lymph node dissection and regional lymph node radiotherapy. The purpose of this study was to evaluate the impact of immediate lymphatic reconstruction or the lymphatic microsurgical preventative healing approach on postoperative lymphedema incidence. METHODS: The authors performed a retrospective review of all patients referred for immediate lymphatic reconstruction at the authors' institution from September of 2016 through February of 2019. Patients with preoperative measurements and a minimum of 6 months' follow-up data were identified. Medical records were reviewed for demographics, cancer treatment data, intraoperative management, and lymphedema incidence. RESULTS: A total of 97 women with unilateral node-positive breast cancer underwent axillary nodal surgery and attempt at immediate lymphatic reconstruction over the study period. Thirty-two patients underwent successful immediate lymphatic reconstruction with a mean patient age of 54 years and body mass index of 28 ± 6 kg/m2. The median number of lymph nodes removed was 14 and the median follow-up time was 11.4 months (range, 6.2 to 26.9 months). Eighty-eight percent of patients underwent adjuvant radiotherapy of which 93 percent received regional lymph node radiotherapy. Mean L-Dex change was 2.9 units and mean change in volumetry by circumferential measurements and perometry was -1.7 percent and 1.3 percent, respectively. At the end of the study period, we found an overall 3.1 percent rate of lymphedema. CONCLUSION: Using multiple measurement modalities and strict follow-up guidelines, the authors' findings support that immediate lymphatic reconstruction at the time of axillary surgery is a promising, safe approach for lymphedema prevention in a high-risk patient population. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Ethical Considerations of Medical Photography in the Management of Breast Disease.

BACKGROUND: Medical photography has become an important component of the evaluation and management of patients across many specialties. It is increasingly utilized in contemporary practice with modern smartphones and enhanced digital media. Photography can enhance and improve treatment plans and communication between providers and patients. Additionally, photography supplements education, research, and marketing in both print and social media. Ethical and medicolegal standards for medical photography, specifically for patients with breast disease, have not been formally developed to guide medical providers. PURPOSE: To provide guidelines for breast care physicians using medical photography, the Ethics Committee of the American Society of Breast Surgeons presents an updated review of the literature and recommendations for ethical and practical use of photography in patient care. METHODS: An extensive PubMed review of articles in English was performed to identify studies and articles published prior to 2018 investigating the use of medical photography in patient care and the ethics of medical photography. After review of the literature, members of the Ethics Committee convened a panel discussion to identify best practices for the use of medical photography in the breast care setting. Results of the literature and panel discussion were then incorporated to provide the content of this article. CONCLUSION: The Ethics Committee of the American Society of Breast Surgeons acknowledges that photography of the breast has become an invaluable tool in the delivery of state-of-the-art care to our patients with breast disease, and we encourage the use of this important medium. Physicians must be well informed regarding the concerns associated with medical photography of the breast to optimize its safe and ethical use in clinical practice.

The Ethics of Breast Surgery.

Breast surgery has evolved as a subspecialty of general surgery and requires a working knowledge of benign and malignant diseases, surgical techniques, shared decision-making with patients, collaboration with a multi-disciplinary team, and a basic foundation in surgical ethics. Ethics is defined as the practice of analyzing, evaluating, and promoting best conduct based upon available standards. As new information is obtained or as cultural values change, best conduct may be re-defined. In 2014, the Ethics Committee of the ASBrS acknowledged numerous ethical issues, specific to the practice of breast surgery. This independent review of ethical concerns was created by the Ethics Committee to provide a resource for ASBrS members as well as other surgeons who perform breast surgery. In this review, the professional, clinical, research and technology considerations that breast surgeons face are reviewed with guidelines for ethical physician behavior.

Locoregional recurrence after mastectomy with immediate transverse rectus abdominis myocutaneous (TRAM) flap reconstruction.

BACKGROUND: The locoregional recurrence (LRR) rate after mastectomy is reported to be similar with immediate reconstruction. We aimed to identify characteristics of LRR after transverse rectus abdominis myocutaneous (TRAM) reconstruction. METHODS: We retrospectively reviewed patients undergoing immediate TRAM reconstruction for breast cancer who were diagnosed with LRR. RESULTS: We identified 18 LRR (4.6 %) in 18 of 390 patients who underwent immediate TRAM reconstructions for breast cancer from 1998 to 2008. The median follow-up was 69.2 months. The mean age at time of mastectomy was 49.5 years. All LRR were detected by physical examination. The LRR occurred in the TRAM subcutaneous tissue (n = 9), five in the ipsilateral axillary lymph node and four in the supraclavicular lymph node. Of the 18 patients who developed LRR, 14 (77.7 %) presented with stage 0-1-2 and 4 (22.2 %) with stage 3 disease at the time of the original mastectomy. The average time for a LRR to present was 35.8 months after initial mastectomy and reconstruction. For patients who initially presented with stage 3 disease, the average time to LRR was shorter (22.9 months). Nine patients (50.0 %) were found to have metastatic disease at the time of the LRR, and 6 (33.3 %) died of disease. CONCLUSIONS: All TRAM LRR were detected by routine physical examination by the patient or the surgeon. Our findings suggest that routine history and clinical breast examination of the breast reconstructed with a TRAM flap along with patient self-awareness are reliable in the diagnosis of LRR.

The utility of breast MRI in the management of breast cancer.

Breast magnetic resonance imaging (MRI) is increasingly used in the evaluation of breast cancer. The impact of this modality on patient management at a single institution is evaluated in this paper. A retrospective review was performed for 114 breast cancer patients who had breast MRI as part of their diagnostic evaluation. Clinical information, mammograms, breast ultrasounds and MRI scans were reviewed to determine whether the MRI findings led to a change in patient management. Outcomes as the result of breast MRI were stratified as favorable and unfavorable. Ninety-five patients who had complete clinical, radiologic, and pathologic data were identified. The indications for breast MRI included: high risk screening (n = 3), diagnostic evaluation of disease after neo-adjuvant chemotherapy (n = 24) or prior to re-excision (n = 8), extent of in situ ductal, infiltrating ductal or infiltrating lobular disease histology (DCIS n = 3, IDC n = 24, ILC n = 17), identification of unknown primary (n = 2), assessment of contralateral breast (n = 4), recurrence surveillance (n = 5), and other (n = 5). MRI was concordant with clinical findings and other modalities in 70.5% of cases. MRI altered planned clinical management in 28 of 95 patients (29.5%). Management changes were favorable in 21 patients (75%). Diagnostic evaluation of the breast by MRI alters patient management in 30% of cases depending upon the indications. Alteration in patient management is favorable in 75% of cases. Evaluation of the breast by MRI alters the clinical management of nearly one-third of patients. Changes are favorable for the majority of these cases. Patients undergoing evaluation for contralateral disease, invasive lobular carcinoma and assessment of chemotherapeutic response may derive a more meaningful benefit from MRI.

Management of the asymptomatic BRCA mutation carrier.

Current management of an asymptomatic BRCA mutation carrier includes early initiation and intensive cancer screening in combination with risk reduction strategies. The primary objectives of these interventions are earlier detection and cancer prevention to increase quality of life and prolonged survival. Existing recommendations are often based on the consensus of experts as there are few, supportive, randomized control trials. Management strategies for unaffected patients with BRCA mutations are continually redefined and customized as more evidence-based knowledge is acquired with regard to current intervention efficacy, mutation-related histology, and new treatment modalities. This review provides an outline of current, supported management principles, and interventions in the care of the asymptomatic BRCA mutation carrier. Topics covered include surveillance modalities and risk reduction achieved through behavioral modification, chemoprevention, and prophylactic surgery.
