The impact of delayed wound healing on patient-reported outcomes after breast cancer surgery.

PURPOSE: Postoperative complications after breast cancer surgery may be associated with decreased quality of life. It remains unclear whether oncoplastic breast-conserving surgery or mastectomy with reconstruction lead to more postoperative complications than conventional breast surgery (CBS). As delayed wound healing (DWH) is one of the most frequent minor complications, we sought to investigate the significance of DWH for patient-reported outcomes after oncoplastic, reconstructive, and CBS. METHODS: Our study is a retrospective cohort study of consecutive patients with stage I-II breast cancer who underwent oncoplastic or CBS performed by three breast surgeons at a single tertiary referral hospital from June 2011 until May 2019. Patient-reported outcomes were evaluated postoperatively using the BREAST-Q questionnaire. Comparisons were made between patients with and without DWH. RESULTS: A total of 229 patients who met the inclusion criteria and 28 (12%) of them developed DWH, 27/158 (17%) in the oncoplastic breast-conserving surgery and reconstruction group and 1/71 (1%) in the CBS group. The mean time from surgery to BREAST-Q assessment was comparable in both groups (29 months in the DWH vs. 33 months in the normal wound healing group). No statistically significant difference for any BREAST-Q scale was detected between patients with and without DWH. This includes physical (p = 0.183), psychosocial (p = 0.489), sexual well-being (p = 0.895), and satisfaction with breasts (p = 0.068). CONCLUSION: Our study confirms that oncoplastic breast-conserving surgery and mastectomy with reconstruction lead to significantly more DWH than CBS. However, neither quality of life nor patient-reported outcomes following state-of-the-art reconstructive or oncoplastic breast-conserving surgery at a specialized center seem to be compromised.

Comparison of patient-reported outcomes among different types of oncoplastic breast surgery procedures.

BACKGROUND: This study aims to compare patient-reported outcomes (PROs) after different types of oncoplastic surgery (OPS) procedures and correlate the results with previously published normative data from women with no prior history of breast cancer (BC) and breast surgery. METHODS: Cross-sectional study of patients with stage I-II BC undergoing a specific selection of OPS procedures from 04/2012 to 12/2018 by three breast surgeons at a single tertiary referral hospital in Switzerland. PROs were evaluated using the postoperative BREAST-Q questionnaire. RESULTS: One hundred twenty-seven patients met the inclusion criteria and were surveyed. All OPS techniques achieved comparably elevated scores in satisfaction with breasts, psychosocial, and sexual well-being. Compared to normative data of healthy women, all OPS groups postoperatively achieved significantly better satisfaction with breasts, psychosocial, and sexual well-being. CONCLUSION: This study shows high PROs across all types of OPS, which were superior to normative data from healthy women. Our findings confirm that OPS is associated with high quality of life and patient satisfaction.

Impact of Oncoplastic Breast Surgery on Rate of Complications, Time to Adjuvant Treatment, and Risk of Recurrence.

BACKGROUND: The aim of this study was to compare the risk of complications and recurrence between oncoplastic and conventional breast surgery. METHODS: This is a retrospective analysis of a consecutive series of 436 patients with stage I-III breast cancer who underwent surgery at the University Hospital of Basel between 2011 and 2018. RESULTS: The nipple/skin-sparing mastectomy (NSM/SSM) group showed significantly more delayed wound healing (32.7 vs. 5.8%, p < 0.001) and skin necrosis (13.9 vs. 1.9%, p = 0.020) compared to conventional mastectomy (CM), which corresponded to significantly higher odds of short-term complications (OR 2.34, 95% CI 1.02-5.35, p = 0.044). The incidence rate of long-term morbidity in oncoplastic breast-conserving surgery (OBCS) was significantly higher compared to conventional breast-conserving surgery (CBCS; 25.5 vs. 11.3 per 100 patient years [PY], p < 0.001), in particular concerning chronic pain (13.3 vs. 6.6, p = 0.011) and lymphedema (4.1 vs. 0.4, p = 0.003). Seroma as a long-term morbidity occurred more often in the CM group compared to the NSM/SSM group (5.8 vs. 0.5 per 100 PY, p = 0.004). Patients received adjuvant treatment earlier after CM compared to NSM/SSM (HR 1.83, 95% CI 1.05-3.19, p = 0.034). There were no significant differences in the incidence of positive margins nor in the odds of recurrence after OBCS versus CBCS and after NSM/SSM versus CM. CONCLUSIONS: Even though the present study confirmed expected differences in complications and morbidity, it suggested that oncoplastic surgery is oncologically safe. Patients undergoing NSM/SSM should be followed closely to allow early detection and treatment of frequently associated complications and ensure timely start of adjuvant therapy.

Improved Adipocyte Viability in Autologous Fat Grafting With Ascorbic Acid-Supplemented Tumescent Solution.

INTRODUCTION: In reconstructive surgery, fat volume augmentation is often necessary for esthetic or functional reasons. As an alternative to synthetic and xenogeneic materials, autologous fat grafting (AFG) based on liposuction is gaining popularity, yet successful transplantation and long-term volume maintenance are difficult. Standard tumescent solution formulations neglect adipocyte and stromal vascular fraction (SVF) cell survival during extraction, as well as SVF differentiation into adipocytes thereafter, all of which are crucial for the success of AFG. Here we hypothesized that addition of ascorbic acid (AA) to the tumescent solution could prevent liposuction-induced cell damage. MATERIALS AND METHODS: The effect of 0.1 mmol/L AA in tumescent solution was investigated in a previously described ex vivo model of AFG. Briefly, excision fat was infiltrated with tumescent solution, with or without AA, and incubated for 20 minutes at 37°C. Hand-assisted liposuction was then performed with a blunt cannula. Total cell viability, clonogenicity, and differentiation capacity of the SVF cells were assessed. RESULTS: With AA, 10.3% more cells and in particular 14.9% more adipocytes survived liposuction. Clonogenicity, adipocyte and osteoblast differentiation by SVF cells remained unchanged. CONCLUSIONS: Addition of AA successfully improved survival of adipocytes during liposuction without affecting SVF growth and differentiation. This study therefore identified a useful supplement to the tumescent solution which may lead to improving AFG success.
