Expanded Indications for Nipple-Sparing Mastectomy and Immediate Breast Reconstruction in Patients Older Than 60 Years.

INTRODUCTION: Although nipple-sparing mastectomy (NSM) and immediate breast reconstruction (IBR) have long been praised for excellent cosmetic results and the resultant psychosocial benefits, the feasibility and safety of these procedures in patients older than 60 years have yet to be demonstrated in a large population. METHODS: Patients undergoing NSM with or without IBR at the MedStar Georgetown University Hospital between 1998 and 2017 were included. Patient demographics, surgical intervention, and complication and recurrence events were retrieved from electronic medical records. Primary outcomes were recurrence and complication rates by age groups older and younger than 60 years. RESULTS: There were 673 breasts from 397 patients; 58 (8.6%) older than 60 years and 615 (91.4%) younger than 60 years with mean follow-up of 5.43 (0.12) years. The mean age for those older than 60 was 63.9 (3.3) years, whereas that for those younger than 60 was 43.1 (7.9) years (P < 0.001). The older than 60 group had significantly higher prevalence of diabetes, rates of therapeutic (vs prophylactic) and unilateral (vs bilateral) NSM, and mastectomy weight. However, there were no significant differences by age group in complication rates or increased risk of locoregional or distant recurrence with age. CONCLUSIONS: Based on similar complication profiles in both age groups, we demonstrate safety and feasibility of both NSM and IBR in the aging population. Despite increased age and comorbidity status, appropriately selected older women were able to achieve similar outcomes to younger women undergoing NSM with or without IBR.

Prognostic Predictors of Mortality in Male Breast Cancer: Outcomes in an Urban Population.

INTRODUCTION: Male breast cancer (MBC) accounts for 0.5% to 1% of all breast cancers diagnosed annually. The purpose of this study is to evaluate prognostic factors in MBC. METHODS: We performed a retrospective chart review of patients with MBC between 2010 and 2021. Demographics, comorbidities, cancer characteristics, recurrence, and mortality were collected. Cox proportional hazards regression model was used to determine prognostic factors. A Kaplan-Meier curve was used to plot survival probabilities. RESULTS: A total of 47 male patients were identified. The mean age at presentation was 64.1 y. Twenty eight (59.6%) patients were African American and 14 patients (29.8%) were Caucasian. Most patients had invasive ductal carcinoma (89.4%) and presented with T1 or T2 tumors (40.4% and 38.3%, respectively). Three patients (6.4%) had a recurrence and eight patients (17%) died. Using mortality as an end point, age (≥ 76.1 y) indicated a hazard ratio (HR) of 1.13 (P = 0.004), diabetes mellitus (HR = 5.45, P = 0.023), atrial fibrillation (HR = 8.0, P = 0.009), end-stage renal disease (HR 6.47, P = 0.023), Eastern Cooperative Oncology Group performance status of 3 (HR = 7.92, P = 0.024), poorly differentiated grade (HR = 7.21, P = 0.033), and metastatic disease (HR = 30.94, P = 0.015) had an increased risk of mortality. Overall survival at 3 y was 79.2%. CONCLUSIONS: Advanced age, diabetes mellitus, atrial fibrillation, end-stage renal disease, Eastern Cooperative Oncology Group score of 3, poorly differentiated tumors, and metastatic disease are unfavorable prognostic factors in MBC. Compared to female breast cancer, MBC showed poorer overall survival.

Nipple-Sparing Mastectomy With Immediate Reconstruction After Breast-Conserving Therapy and Radiation: Complications and Oncologic Safety.

INTRODUCTION: Nipple-sparing mastectomy (NSM) offers improved, patient-centered outcomes with demonstrated oncologic safety ( Ann Surg Oncol 2020;27:344-351). Indications for NSM continue to expand to patients outside of the traditional eligibility criteria, including those with prior breast-conserving therapy (BCT) with radiotherapy. Currently, limited data exist evaluating both short- and long-term outcomes in patients proceeding to NSM after prior BCT. METHODS: All patients undergoing bilateral NSM in a single institution from 2002 through 2017 with history of prior BCT were included in the final cohort, without exclusions. A retrospective chart review was performed to identify patient demographics, operative details, and complications. Outcomes assessed included early complications (<30 days from NSM), late complications (>30 days), rates of prosthetic failure, unplanned reoperations, and reconstructive failures, as well as oncologic safety. Student t , χ 2 , and Fisher exact tests were used to analyze outcomes of paired (BCT vs non-BCT) breasts within each patient. RESULTS: A total of 17 patients undergoing 34 NSMs were included. Each had a history of BCT and either ipsilateral breast recurrence (64.7%), risk-reducing NSM (23.5%), or a new contralateral primary cancer (11.8%). The cohort had a mean age of 51.1 years. With regard to acute complications (ischemia, infection, nipple-areolar complex or flap ischemia or necrosis, and wound dehiscence), there was no significant difference noted between breasts with prior BCT versus no prior BCT overall (41.2% vs 35.3%, respectively; P = 0.724). Complications occurring after 30 days postoperatively (capsular contracture, contour abnormality, animation deformity, bottoming out, rotation, and rippling) in prior BCT breasts versus no prior BCT had no significant differences overall (58.8% vs 41.2% respectively; P = 0.303). The mean follow-up was 5.5 years, during which no patients had a reported locoregional or distant recurrence in either breast. CONCLUSIONS: No significant differences in early or late complications were identified between breasts in patients undergoing bilateral NSM with a history of unilateral BCT and XRT. In the 5.5 years of follow-up, there were no recurrences, lending support to NSM for management of recurrent disease in addition to National Comprehensive Cancer Network-recommended total mastectomy. We propose that NSM should not be contraindicated in patients exposed to radiation with BCT.

Hospital System Adoption of Magnetic Seeds for Wireless Breast and Lymph Node Localization.

BACKGROUND: As an alternative to traditional wire localization, an inducible magnetic seed system can be used to identify and remove nonpalpable breast lesions and axillary lymph nodes intraoperatively. We report the largest single-institution experience of magnetic seed placement for operative localization to date, including feasibility and short-term outcomes. METHODS: Patients who underwent placement of a magnetic seed in the breast or lymph node were identified from July 2017 to March 2019. Imaging findings, core needle biopsy, surgical pathology results, and type of surgery were collected. Outcomes included procedural complications, magnetic seed and biopsy clip retrieval rates, and need for additional surgery. RESULTS: A total of 842 magnetic seeds were placed by nine radiologists in 673 patients and retrieved by six surgeons at six operative locations. The majority of breast lesions were malignant (395/659, 59.9%); 136 seeds were placed for lymph node localization. The overall magnetic seed retrieval rate was 98.6%, whereas the biopsy clip retrieval rate was 90.9%. Only six patients (0.7%) experienced a complication from magnetic seed placement. Reexcision was performed in 15.2% of patients with breast cancer; 9.6% of benign/high risk lesions were upgraded to malignancy at surgical excision. CONCLUSIONS: The magnetic seed technique is safe, effective, and accurate for localization of breast lesions and lymph nodes, and importantly uncouples surgery from the localization procedure. The high magnetic seed retrieval rate and low reexcision rate may reflect the accuracy of magnetic marker placement as a "second chance" localization procedure, especially in cases with biopsy clip migration.

Contralateral axillary sentinel lymph node in breast cancer recurrence.

The rare but significant reports of aberrant lymph node drainage outside of the ipsilateral axilla in patients with breast cancer necessitate a review of the staging and treatment strategies for these patients. Current staging modalities continue to describe this phenomenon as a stage IV cancer, which could have profound implications for clinical management. We report a case of a patient with recurrent right breast invasive ductal carcinoma whose preoperative lymphoscintigraphy revealed sentinel lymph node drainage to the contralateral axilla. This discovery subsequently altered surgical planning and her ultimate stage.

Critical evaluation of factors contributing to time to mastectomy within a single health care system.

Increased time to mastectomy (TTM) has significant implications for mortality, well-being, and satisfaction. However, certain populations are subject to disparities that increase TTM. This study examines vulnerable populations and the patient-, disease-, provider-, and system-level factors related to treatment delays. Patients undergoing mastectomy for breast cancer from 2014 to 2018 across 8 hospitals in a single health care system were retrospectively reviewed. Demographics, disease characteristics, and provider- and system-level information were collected. Time from biopsy-proven diagnosis to mastectomy was calculated. Univariate analysis identified variables for inclusion in the multivariable model. One thousand, three hundred thirty patients met inclusion. Median TTM was 55.0 days. Factors from all levels-patient, disease, provider, and systemic-were significantly related to disparities. African-American patients had 11.6% longer TTM compared to white patients (69.0 vs 56.0 days, P < .0001). TTM was 15.5% longer for low-income patients when compared to high-income patients (65.0 vs 49.0 days, P = .0014). Preoperative plastic surgery visits led to 19.3% longer TTM (P = .0012); oncologic appointments for neo-adjuvant chemotherapy led to a 231.0% increase (P < .0001). Average time from last neo-adjuvant treatment to mastectomy was 44.4 days (SD 26.5); average TTM from diagnosis for patients not receiving neo-adjuvant chemotherapy was 58.5 days (SD 13.3). Patients with Medicaid waited 14.5% longer compared to patients with commercial insurance (94.0 vs 62.0 days, P = .0005). In our review of care across a large health care system, we identified multiple levels contributing to disparities in TTM. Identification of these disparities offers valuable insight into process improvement and intervention.

A case of necrotizing fasciitis of the breast following lumpectomy and oncoplastic closure.

BACKGROUND: NF is a life-threatening soft tissue infection that most commonly occurs in the lower extremity. While presenting symptoms such as erythema, severe pain, sepsis, and wound crepitation are well documented, diagnosis of NF of the breast often is obscured by a low clinical index of suspicion due to its relative rarity as well as by the breast parenchyma that physically separates the underlying fascia and overlying skin. Several risk factors have previously been identified, such as underlying infection, diabetes, advanced age, and immunosuppression. However, the gross morbidity and high mortality associated with NF warrant continued surveillance of contributing factors across any anatomic location. Fifteen cases in the literature document the development of NF following breast surgery. CASE REPORT: The authors of this case report aim to expand on the current literature through the presentation of a unique case of NF of the breast following right breast lumpectomy and oncoplastic closure with left reduction mammaplasty in an immunocompromised patient found to have concurrent perforated sigmoid diverticulitis. CONCLUSION: This case exemplifies how frequent postoperative surveillance, a low threshold for intervention, and efficient coordination of care are vital to minimizing the morbidity and mortality risks associated with NF of the breast.

Prophylactic Lymphovenous Bypass at the Time of Axillary Lymph Node Dissection Decreases Rates of Lymphedema.

Background: Breast cancer-related lymphedema impacts 30% to 47% of women who undergo axillary lymph node dissection (ALND). Studies evaluating the effectiveness of prophylactic lymphovenous bypass (LVB) at the time of ALND have had small patient populations and/or short follow-up. The aim of this study is to quantitatively and qualitatively evaluate prophylactic LVB in patients with breast cancer. Methods: A retrospective review of patients who underwent ALND from 2018 to 2022 was performed. Patients were divided into cohorts based on whether they underwent prophylactic LVB at the time of ALND. Primary outcomes included 30-day complications and lymphedema. Lymphedema was quantitatively evaluated by bioimpedance analysis, with L-dex scores >7.1 indicating lymphedema. Results: One-hundred five patients were identified. Sixty-four patients (61.0%) underwent ALND and 41 patients (39.0%) underwent ALND+LVB. Postoperative complications were similar between the cohorts. At a median follow-up of 13.3 months, lymphedema occurred significantly higher in the ALND only group compared with ALND+LVB group (50.0% vs 12.2%; P < 0.001). ALND without LVB was an independent risk factor for lymphedema development (odds ratio, 4.82; P = 0.003). Conclusions: Prophylactic LVB decreases lymphedema and is not associated with increased postoperative complications. A multidisciplinary team approach is imperative to decrease lymphedema development in this patient population.

Modified goldilocks nipple-sparing mastectomy with immediate prepectoral implant-based reconstruction: a case report.

Background: Nearly 80% of women who undergo post-mastectomy reconstruction opt for implant-based reconstruction. Preservation of the nipple-areolar complex (NAC) in nipple-sparing mastectomy (NSM) significantly improves patient satisfaction; however in women with macromastia or breast ptosis, NAC preservation carries an increased risk of nipple ischemia. Traditional options have included free nipple grafts or a staged reconstruction, however in patients with aggressive or multifocal breast cancer, this is not feasible due to the need for timely oncologic resection. The Goldilocks mastectomy, which utilizes redundant adipodermal tissue to recreate a breast mound, was originally designed for women with large or ptotic breasts who did not desire post-mastectomy reconstruction. However, this technique has been modified in several ways. In this case report, we present our approach to a patient with breast ptosis and multifocal breast cancer who desired NAC preservation, volume preservation and mastopexy using the modified Goldilocks technique with pre-pectoral implant-based reconstruction. Case Description: A 38-year-old woman, with a bra size of 36C, presented with grade II, multifocal, estrogen receptor positive, progesterone receptor negative, human epidermal growth factor receptor-2 positive right breast infiltrating ductal carcinoma. The patient's aesthetic goals included: preservation of the NACs, elevation of NAC position, reduction in areola diameter, and maintenance of breast volume using implant-based reconstruction. As a result of her multifocal breast cancer, she was not a candidate for staged mastopexy followed by mastectomy and reconstruction. Therefore, the patient underwent bilateral Goldilocks NSM, right sentinel lymph node biopsy, and immediate implant-based reconstruction using the modified Goldilocks technique with acellular dermal matrix (ADM). At 3-month follow-up, the patient was satisfied with the overall aesthetic outcome of her breasts. Conclusions: We present a patient with breast ptosis and multifocal breast cancer who desired NAC preservation and implant-based reconstruction, but was not a candidate for staged reoperation. This case report is the first to describe a modified Goldilocks NSM with pre-pectoral implant-based reconstruction.

Reduction in tumor grade and Ki-67 in postmenopausal patient with node-positive invasive ductal carcinoma following combination hormone replacement therapy cessation: a case report.

Background: While praised for its benefits in treating symptoms related to menopausal changes, hormone replacement therapy (HRT) has been associated with an increased risk for hormone-dependent cancer development, particularly endometrial and breast. Few studies have elucidated the relationship between HRT cessation and hormone receptor-positive breast cancer proliferation. We report herein, to the best of our knowledge, the first case of 28.6% relative reduction in proliferation index marker Ki-67 in node-positive hormone receptor-positive breast cancer following HRT cessation. Case Description: We report an unusual case of a 64-year-old female patient with longstanding HRT for fifteen years who underwent immediate discontinuation after diagnosis of poorly differentiated invasive ductal carcinoma. We observed a reduction in tumor grade from poorly differentiated at time of biopsy to moderately differentiated at time of surgery following cessation of HRT, as well as a reduction in the tumor proliferation index (Ki-67) from 70% to 50%. The patient has remained recurrence-free at the one-year mark postoperatively with continued follow-up. Conclusions: This case highlights potential clinical benefits associated with HRT discontinuation in the postmenopausal population with preexisting hormone-dependent cancers with high proliferation index, as well as the usefulness of Ki-67 in measuring response to aromatase inhibition in this subpopulation of patients. Keywords: Hormone replacement therapy (HRT); breast cancer; tumor grade; Ki-67; case report.

Triple negative breast cancer and reconstruction: Predictors of recurrence, complications, and mortality.

BACKGROUND: Only 42% of all breast cancer patients undergoing mastectomy elect for breast reconstruction. OBJECTIVE: We evaluate factors impacting complications, recurrence, and mortality in triple-negative breast cancer (TNBC) patients undergoing reconstruction. METHODS: Reconstructive TNBC patients at a single institution from 2010 to 2020 were retrospectively reviewed. Patient demographics, cancer characteristics, reconstruction choice, and complications were collected. Statistical significance was defined at p < 0.05. RESULTS: A total of 131 patients were identified. Average age was 47.8 years, 50.4% were Caucasian and 36.4% were African American. Most patients had invasive ductal carcinoma (90.8%), and most underwent nipple-sparing (41.2%) or skin-sparing (38.9%) mastectomies. Twenty-one patients (16.0%) experienced postoperative complications. Patients with complications tended to be older (52.1 versus 46.9 years, p = 0.052). At mean follow-up of 52.1 months, 14.5% experienced cancer recurrence and 5.3% died. Deceased patients were significantly younger at diagnosis (42.2 versus 48.5 years, p = 0.008) and had a lower BMI compared to surviving patients (21.2 versus 26.9 kg/m2; p = 0.014). Patients younger than age 45 years had higher Ki-67 than those older than 45 years (80.0% versus 60.0%, p = 0.013). Outcomes in autologous- versus implant-based reconstruction were not significantly different. CONCLUSIONS: In TNBC post-mastectomy reconstruction patients, age and BMI were predictors of mortality while race, smoking history, reconstruction choice, or type of implant-based reconstruction had no significant effect on these outcomes. SYNOPSIS: The purpose of this study is to evaluate factors that impact complications, recurrence, and mortality in triple negative breast cancer (TNBC) patients undergoing reconstruction. We identified BMI, neoadjuvant chemotherapy, and age as predictors of complications, recurrence, and mortality in TNBC.

Smart Self-Assembling MagnetS for ENdoscopy (SAMSEN) for transoral endoscopic creation of immediate gastrojejunostomy (with video).

BACKGROUND: Gastrojejunostomy is important for palliation of malignant gastric outlet obstruction and surgical obesity procedures. A less-invasive endoscopic technique for gastrojejunostomy creation is conceptually attractive. Our group has developed a compression anastomosis technology based on endoscopically delivered self-assembling magnets for endoscopy (SAMSEN) to create an instant, large-caliber gastrojejunostomy. OBJECTIVE: To develop and evaluate an endoscopic means of gastrojejunostomy creation by using SAMSEN. SETTING: Developmental laboratory and animal facility. DESIGN: Animal study and human cadaveric study. SUBJECTS: Yorkshire pigs (7 cadaver, 5 acute); human (1 cadaver). INTERVENTIONS: A transoral procedure for SAMSEN delivery was developed in porcine and human cadaver models. Subsequently, gastrojejunostomy creation by using SAMSEN was performed in 5 acute pigs. The endoscope was advanced into the peritoneal cavity through the gastrotomy, and a segment of the small bowel was grasped and pulled closer to the stomach. An enterotomy was created, and a custom overtube was advanced into the small bowel for deployment of the first magnetic assembly. Next, a reciprocal magnetic assembly was deployed in the stomach. The 2 magnetic systems were mated under fluoroscopic and endoscopic guidance. Contrast studies assessed for gastrojejunostomy leak. Immediate necropsies were performed. MAIN OUTCOME MEASUREMENTS: Technical feasibility and complications. RESULTS: Gastrojejunostomy creation by using SAMSEN was successful in all 5 animals. Deep enteroscopy was performed through the stoma without difficulty. No leaks were identified on contrast evaluation. At necropsy, the magnets were properly deployed and robustly coupled together, resistant to vigorous tissue manipulation. LIMITATIONS: Acute animal study. CONCLUSIONS: Endoscopic creation of immediate gastrojejunostomy by using SAMSEN is technically feasible.

Management of invasive ductal carcinoma in hypermobile Ehlers-Danlos syndrome: a case report.

Literature is sparse regarding the management and long-term outcomes of breast cancer in patients with Ehlers-Danlos syndrome (EDS). Of the EDS subtypes, hypermobile Ehlers-Danlos Syndrome (hEDS) is associated with cardiovascular dysautonomia which manifests as spontaneous episodes of tachycardia and hypotension. Given this clinical autonomic system impact, hEDS is known to have significant intraoperative risk and postoperative complications. However, outcomes of hEDS patients have not been specifically studied in the field of breast cancer surgery. Here we present a case of a 62-year-old female with hEDS and node-positive invasive ductal breast carcinoma. Given the patient's medical history of hEDS, close attention was given to the patient's intraoperative vital signs and predisposition for poor wound healing. The patient underwent left Goldilocks mastectomy with left axillary lymph node dissection. Due to cardiac comorbidities, she was not a candidate for neoadjuvant or adjuvant chemotherapy. The patient tolerated adjuvant radiation and endocrine therapy without side effects, and has remained free of local, regional, and distant cancer recurrence following treatment. This case report highlights a literature gap in the surgical and radiation therapy management of breast cancer in patients with hEDS. Although breast surgery and radiation therapy in patients with invasive breast cancer and hEDS can be a safe management option, we discuss how perioperative complications must be cautiously navigated and how treatment must be tailored to individuals' specific hEDS variant to ensure optimal patient safety and positive long-term outcomes.

Precision Medicine and Targeted Therapies in Breast Cancer.

Precision medicine and targeted therapies have a long history in the treatment of breast cancer and continue to show promise for further specialized and individualized care for this disease. From the discovery of endocrine and HER2 targeted therapies, to multigene arrays in chemotherapy for more specific patient selection, to radiomics and genetic subtyping, targeted therapies and precision medicine continue to push the management of breast cancer toward more individualized care. This article describes the foundation and future of targeted therapy and precision medicine in breast cancer.

Free Silicone Injections to the Breast: Delayed Complications and Surgical Management of Sequelae.

This case describes a healthy 37-year-old woman who presented with bilateral breast pain and nodules years after receiving free silicone injections to her breasts. Mammogram revealed extremely dense breasts with innumerable bilateral masses of various sizes. Ultrasound was non-diagnostic due to poor penetration and artifact from silicone. Histologic examination revealed vacuolated histiocytes and innumerable cystic spaces containing material consistent with silicone. Patient underwent bilateral nipple-sparing mastectomy with immediate reconstruction using tissue expanders. This case highlights the potential for serious complications developing years after free silicone injections as well as our team's surgical management of these complications.
