Preoperative MRI and Its Impact on Surgical Outcomes in Patients with Triple Negative Breast Cancer Treated with Primary Surgery: Did New Margin Guidelines or Cavity Shave Margins Practice Diminish the Role of Preoperative MRI?

BACKGROUND: Results of an earlier retrospective study from our institution suggested that patients with triple negative breast cancer (TNBC) who had preoperative MRI may have had an improved local recurrence rate (LRR) after breast conserving surgery (BCS). We aimed to clarify the impact of preoperative MRI on surgical outcomes in an expanded TNBC cohort treated by BCS in a contemporary era. METHODS: Our study cohort comprised 648 patients with TNBC who underwent BCS between 2009 and 2018. Demographic and clinical characteristics were compared between those with (n = 292, 45.1%) and without (n = 356, 54.9%) preoperative MRI. Multivariable logistic regression was performed to assess the association of preoperative MRI with surgical outcomes. RESULTS: The crude LRR of 3.5% was lower than previously reported. Univariable analyses demonstrated that the LRR and re-excision rates in the MRI and no-MRI groups were 3.4 and 3.7%, 21.6% and 27.2%, p = 0.876 and p = 0.10, respectively. Multivariable logistic regression analyses demonstrated that preoperative MRI was not associated with a lower LRR: odds ratio (OR) = 1.42 (p = 0.5). During our study period, new margin guidelines and shave margins practice were adopted in 2014 and 2015. To account for their effects, the year of diagnosis/surgery and other clinical variables were adjusted in multivariable logistic regression and inverse probability weighting models to demonstrate that preoperative MRI remained associated with a lower re-excision risk, OR 0.56, p = 0.04l; and a lower re-excision rate, 23.15% versus 36.0%, p < 0.01, respectively. CONCLUSIONS: Our findings suggested that patients with TNBC anticipating BCS may benefit from preoperative MRI.

Quality of life and sexual well-being after nipple sparing mastectomy: A matched comparison of patients using the breast Q.

BACKGROUND: Nipple sparing mastectomy (NSM) is considered safe for select patients. Our objective was to examine quality of life (QOL) and satisfaction for NSM compared with skin sparing mastectomy (SSM). We aimed to evaluate these using the BREAST-Q. METHODS: After IRB approval, we analyzed patients who underwent NSM and reconstruction between July 2010-June 2015. NSM patients were matched with those after SSM based on age, race, and body mass index. Telephone interviews were prospectively conducted using the BREAST-Q Mastectomy Postoperative Module. Bivariate analysis and a paired samples t-test were performed. RESULTS: We identified 43 patients meeting our inclusion criteria with a response rate 60% (N = 26). NSM and SSM patients were matched well in age (P = 1.00), race (P = 1.00), and Body Mass Index (P = 0.99). There were no significant differences in stage, estrogen and progesterone status, HER2 expression, reconstruction type and radiation. Mean BREAST-Q scores did not vary between NSM and SSM in regards to satisfaction with breasts (P = 0.604), psychosocial well-being (P = 0.146), physical well-being (P = 0.121), and satisfaction with surgeon (P = 0.170). Sexual well-being was significantly higher in NSM patients (P = 0.011). CONCLUSION: NSM provides patients with favorable results in psychosocial, sexual, and physical well-being and overall satisfaction. Sexual well-being showed significant improvement for NSM.

Locoregional Cancer Recurrence after Breast Reconstruction: Detection, Management, and Secondary Reconstructive Strategies.

BACKGROUND: Locoregional recurrence of the previously reconstructed breast poses a diagnostic and operative challenge. This study examines detection, management, and reconstructive strategies of locoregional recurrence following postmastectomy breast reconstruction. METHODS: A retrospective review of records was performed on patients treated within the health system for breast cancer from January of 2000 to July of 2014. Of these patients, descriptive factors and operative details were collected for those that developed locoregional recurrence. Subsequent reconstructive operations were also examined. Using a multidisciplinary team, a surveillance/management algorithm was generated. RESULTS: A total of 41 patients with locoregional recurrence were identified (mean time to recurrence, 4.6 years). Two- and 5-year survival following locoregional recurrence was 88 percent and 39 percent, respectively. Locoregional recurrence was found to occur in the following tissue planes: subcutaneous (27 percent), subcutaneous/pectoralis (24 percent), chest wall (37 percent), and axillary (12 percent). The most frequent method of detection was patient concern leading to examination. Older age at the time of locoregional recurrence (p = 0.028), increased time to recurrence/detection (p = 0.024), and chemotherapy before locoregional recurrence (p = 0.014) were associated with the need for a secondary salvage flap. Patients who experienced a subcutaneous recurrence were far less likely to undergo a secondary flap (p = 0.011). Factors associated with loss of the index reconstruction included lower body mass index (p = 0.009), pectoralis invasion (p = 0.05), and implant reconstruction (p = 0.03). CONCLUSIONS: Detection and management of locoregional recurrence requires appropriate physical examination and imaging. Significant factors associated with failure to salvage the initial reconstruction included body mass index, plane of recurrence, and type of initial reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Self-reported changes in the professional singing voice after surgical intervention treatment for breast cancer: a survey pilot study of female professional singers.

BACKGROUND: The effects of breast cancer surgical treatment on the professional singing voice are unknown. OBJECTIVE: The purpose of this study was to discover whether there are self-perceived changes in the quality and/or process of singing experienced by professional female singers who have undergone surgical intervention for the treatment of diagnosed breast cancer-including any changes perceived from the use of radiation, chemotherapy, and other drug treatments related to those surgeries. METHODS: A voluntary subject pool comprised female professional singers who have undergone surgery for breast cancer was recruited from professional singing networks. Participants underwent evaluation through an anonymous online survey, psychometrically vetted for content and instrument reliability/validity before administration. RESULTS: Valid participants (N=56) responded to 45 questions regarding surgical procedures, related therapies, and self-perceived vocal effects. Analysis of results produced a preliminary description of types of voice change, duration of changes, and qualitative self-perceptions. CONCLUSIONS: This initial report reveals that there are self-perceived singing voice changes experienced by professional singers treated for breast cancer. However, additional research is needed to determine the degree of vocal impact perceived to be attributable to individual surgical interventions and related therapies.
