RESUMEN
BACKGROUND: The National Comprehensive Cancer Network guidelines were designed to improve patient outcomes. Here, we examine factors that may contribute to outcomes and guideline adherence in patients with triple-negative breast cancer. METHODS: This was a retrospective cohort study of women with triple-negative breast cancer using the California Cancer Registry. Adherent treatment was defined as the receipt of a combination of surgery, lymph node assessment, adjuvant radiation, and/or chemotherapy. A multivariable logistic regression was used to determine the effects of independent variables on adherence to the NCCN guidelines. Disease-specific survival was calculated using Cox regression analysis. RESULTS: A total of 16,858 women were analyzed. Black and Hispanic patients were less likely to receive guideline-adherent care (OR 0.82, 95%CI 0.73-0.92 and OR 0.87, 95%CI 0.79-0.95, respectively) compared to White patients. Hazard ratios adjusted for adherent care showed that Black patients had increased disease-specific mortality (HR 1.28, 95%CI 1.16-1.42, p < 0.0001) compared to White patients. CONCLUSIONS: A significant majority of breast cancer patients in California continue to receive non-guideline-adherent care. Non-Hispanic Black patients and patients from lower SES quintile groups were less likely to receive guideline-adherent care. Patients with non-adherent care had worse disease-specific survival compared to recipients of NCCN guideline-adherent care.
RESUMEN
BACKGROUND: The locoregional recurrence of breast cancer has been reduced due to the multidisciplinary approach of breast surgery, systemic therapy and radiation. Early detection and better surgical techniques contribute to an improvement in breast cancer outcomes. PURPOSE OF REVIEW: The purpose of this review is to have an overview and summary of the current evidence behind the current approaches to the locoregional treatment of breast cancer and to discuss its future direction. SUMMARY: With improved surgical techniques and the use of a more effective neoadjuvant systemic therapy, including checkpoint inhibitors and dual HER2-directed therapies that lead to a higher frequency of pathologic complete responses and advances in adjuvant radiation therapy, breast cancer patients are experiencing better locoregional control and reduced local and systemic recurrence. De-escalation in surgery has not only improved the quality of life in the majority of breast cancer patients, but also maintained the low risk of recurrence. There are ongoing clinical trials to optimize radiation therapy in breast cancer. More modern radiation technologies are evolving to improve the patient outcome and reduce radiation toxicities.

Breast stromal lesions include fibroadenomas, phyllodes tumors, pseudoangiomatous stromal hyperplasia, periductal stromal tumors, and lipomas. Most of these lesions are benign and can be managed with observation or surgical excision. Phyllodes tumors, however, are subcategorized into benign, borderline, and malignant. Benign phyllodes tumors may be removed without a margin of breast tissue while borderline and malignant phyllodes tumors need a wide excision with a greater than 1 cm margin. Because malignant phyllodes tumors have a poor prognosis, efforts should be made to discuss their treatment in a multidisciplinary setting and enrollment in a clinical trial should be considered.

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.

PURPOSE: To develop recommendations concerning the management of male breast cancer. METHODS: ASCO convened an Expert Panel to develop recommendations based on a systematic review and a formal consensus process. RESULTS: Twenty-six descriptive reports or observational studies met eligibility criteria and formed the evidentiary basis for the recommendations. RECOMMENDATIONS: Many of the management approaches used for men with breast cancer are like those used for women. Men with hormone receptor-positive breast cancer who are candidates for adjuvant endocrine therapy should be offered tamoxifen for an initial duration of five years; those with a contraindication to tamoxifen may be offered a gonadotropin-releasing hormone agonist/antagonist plus aromatase inhibitor. Men who have completed five years of tamoxifen, have tolerated therapy, and still have a high risk of recurrence may be offered an additional five years of therapy. Men with early-stage disease should not be treated with bone-modifying agents to prevent recurrence, but could still receive these agents to prevent or treat osteoporosis. Men with advanced or metastatic disease should be offered endocrine therapy as first-line therapy, except in cases of visceral crisis or rapidly progressive disease. Targeted systemic therapy may be used to treat advanced or metastatic cancer using the same indications and combinations offered to women. Ipsilateral annual mammogram should be offered to men with a history of breast cancer treated with lumpectomy regardless of genetic predisposition; contralateral annual mammogram may be offered to men with a history of breast cancer and a genetic predisposing mutation. Breast magnetic resonance imaging is not recommended routinely. Genetic counseling and germline genetic testing of cancer predisposition genes should be offered to all men with breast cancer.

BACKGROUND AND OBJECTIVES: Autologous breast reconstruction (BR) can be a stressful life event. Therefore, women undergoing mastectomy and autologous BR are required to have sufficient coping mechanisms. Although mental health problems are widespread, information regarding the prevalence of psychiatric diagnosis among these patients is scarce. METHODS: Retrospective analysis was performed using data from a large tertiary teaching hospital and the Nationwide Inpatient Sample (NIS) database. Patients undergoing autologous BR after mastectomy were included and evaluated for psychiatric disorders. Prevalence of each disorder, timing of diagnosis (preoperative or postoperative), and data per age group were reviewed. RESULTS: Between 2004 and 2014, 817 patients were included from the institutional database and 26 399 from the NIS database. Preoperatively, 15.3% of the patients were diagnosed with a psychiatric disorder within our institution and 17.6% nationwide (P < 0.001). Postoperatively, 20.5% of the institutional patients were diagnosed with a psychiatric disorder. No major differences in prevalence were seen between age groups. CONCLUSIONS: Approximately, one in six patients were diagnosed with a psychiatric comorbidity preoperatively. Postoperatively, an additional 20.5% developed a psychiatric disorder. There was no difference in prevalence and timing of diagnosis between age groups.

BACKGROUND AND OBJECTIVES: Oncoplastic reconstruction allows more patients to become candidates for breast-conserving surgery (BCS). Oncologic resection of a breast lesion is combined with plastic surgical techniques to improve aesthetic results. Choosing the best oncoplastic method is essential to optimize outcomes, improve cosmesis, and minimize postoperative complications. The aim of this study is to present a treatment algorithm incorporating oncoplastic techniques based on diagnosis, tumor size, tumor location, and breast size and shape. METHODS: A retrospective pilot study of a prospectively collected database was conducted in patients undergoing immediate oncoplastic surgery from 2010 to 2015 at our institution. Oncoplastic surgical techniques were defined as complex layered closure, local tissue rearrangement, pedicled flap, mastopexy, bilateral reduction, or implant placement. Clinical, demographic, and histopathologic data were extracted from electronic patient records. Patient satisfaction was measured by the BREAST-Q questionnaire. RESULTS: A total of 42 women and 46 breasts were included. An algorithm was formulated to assist in selecting an optimal oncoplastic reconstruction plan after BCS. Additionally, patient satisfaction with good aesthetic results was reported. CONCLUSION: In this study, the authors present a reconstructive algorithm describing various oncoplastic approaches aimed to provide a guideline in clinical practice when employing oncoplastic surgery.

BACKGROUND: Nipple-sparing mastectomies (NSM) are increasingly common because of their cosmetic advantage. Radiotherapy (RT) has been a relative contraindication to immediate reconstruction because of concerns about increased complications. We aimed to evaluate outcomes of NSM plus immediate reconstruction in irradiated breasts and to determine additional risk factors for complications. METHODS: We retrospectively reviewed NSM with immediate reconstruction from 2007 to 2013 at our institution. Complications were broken down into several categories. Potential risk factors for complications were evaluated. RESULTS: There were 982 NSM: 816 had no RT, 67 had prior RT, and 97 had postmastectomy radiotherapy (PMRT). Compared to breasts with no RT, both prior RT and PMRT increased overall complications (10.2 vs. 21.7 and 17.5%, p = 0.003, 0.03, respectively) and nipple loss (0.9 vs. 4.3 and 4.1%, p = 0.04, 0.02, respectively), while PMRT increased rate of reconstruction failure (2.2 vs. 8.2%, p = 0.003). On multivariate regression analysis, prior RT [odds ratio (OR) 2.53, p = 0.006], PMRT (OR 2.29, p = 0.015), age >55 years (OR 2.03, p = 0.04), breast volume ≥800 cm(3) (OR 1.96, p = 0.04), smoking (OR 2.62, p = 0.001), and periareolar incision (OR 1.74, p = 0.03) were independent risk factors for complications requiring surgical revision. In irradiated breasts, complication rates were 13.4% without further risk factors and 17.5, 50, and 66.7% when 1, 2, and ≥3 additional independent risk factors were present, respectively (p < 0.001). CONCLUSIONS: Although complication rates were higher in irradiated breasts, reconstruction failure and nipple/areola necrosis was infrequent. RT should not be a contraindication to NSM. Preoperative identification of risk factors and appropriate patient selection may reduce complication rates.

Neoadjuvant therapy (NAC) is commonly used in operable breast cancer. Previous studies have suggested a high rate of postoperative complications after NAC. We prospectively evaluated the surgical complications in a cohort of patients who underwent mastectomy following neoadjuvant adriamycin/cytoxan/taxol (AC/T) plus bevacizumab (bev) and compared the rate of complications to a matched cohort of neoadjuvant AC/T without bev. One hundred patients with HER2-negative breast cancer enrolled in a single-arm trial of neoadjuvant AC/T plus bev (cohort 1), 60 of these patients underwent mastectomy and were matched with 59 patients who received standard neoadjuvant AC/T (cohort 2) over a similar time period in the same healthcare system. All patients underwent mastectomy with or without reconstruction. Fisher's exact tests were used to compare complication rates, with p < 0.05 considered significant. Patients were matched well in terms of demographics. The overall complication rate was 32 % in cohort 1 and 31 % in cohort 2 (p value = 1, Table 1). In cohort 1, 7 of 23 (30 %) patients who underwent immediate expander/implant reconstruction had complications, including 2 patients who had explantation of their reconstructions. In cohort 2, 0 of 8 (0 %) had complications (p value = 0.15). Nearly a third of patients undergoing NAC with AC/T with or without bev developed a postoperative complication after mastectomy. The use of bev was not associated with a significant increase in surgical complications, although this is a nonrandomized data set with a small sample size. As larger data sets become available with the use of neoadjuvant bevacizumab with mastectomy, further refinement may be necessary.

BACKGROUND: Eligibility for nipple-sparing mastectomy (NSM) varies widely on the basis of patient and tumor factors. METHODS: Review of patients undergoing NSM from June 2007 to December 2012 at our institution was performed. Patient and tumor characteristics, complications, and recurrences were collected. NSM from 2007 to 2010 and 2011 to 2012 were compared to assess trends in eligibility and outcomes over time. RESULTS: NSM was performed on 645 breasts in 370 patients. Indications were risk reduction in 330 (51.2 %), invasive cancer in 226 (35.0 %), and ductal carcinoma-in situ in 89 (13.8 %) breasts. Fifty-one (13.8 %) patients had positive lymph nodes. Twenty-seven (7.3 %) patients received neoadjuvant chemotherapy. Forty-eight (7.4 %) breasts had prior radiotherapy. Total nipple necrosis occurred in 11 (1.7 %) breasts. Twenty-four (3.7 %) breasts had nipples removed as a result of positive subareolar/nipple margins. At 22 months' mean follow-up, local recurrence occurred in 4 of 156 (2.6 %) breasts operated on for cancer through 2011. No recurrences involved the nipple. NSM performed in 2011-2012 (n = 475) compared to 2007-2010 (n = 170), were more often for cancer, in patients with higher body mass index, and on larger breasts (p < 0.001). There was no significant difference in total nipple necrosis rates between groups. Nipple loss due to positive subareolar/nipple margins was significantly less in 2011-2012 (p = 0.027). CONCLUSIONS: Eligibility for NSM has expanded to include women with higher body mass index and larger breasts, with no increase in nipple loss due to ischemia. Rates of positive subareolar margins have decreased over time, even though NSM is being performed more frequently for cancer, suggesting improved patient selection.
