Prognostic analysis of breast-conserving surgery or mastectomy in patients with stage Ⅰ-Ⅲ triple-negative breast cancer
Journal Title: Journal of Surgery : Concepts & Practice - Year 2023, Vol 28, Issue 4
Abstract
[Objective:] To investigate the effect of breast-conserving surgery (BCS) or mastectomy (M) in patients with stage Ⅰ-Ⅲ triple-negative breast cancer (TNBC) on disease free survival (DFS) and overall survival (OS). [Methods:] A total of 844 patients with stage Ⅰ-Ⅲ TNBC who were admitted to Comprehensive Breast Health Center, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine from January 2009 to December 2018 were collected and divided into BCS and M groups according to the surgical method. COX regression analysis was used to evaluate the influence of clinical characteristics and surgical methods on DFS and OS of the patients. The propensity score was further used to balance the differences in baseline characteristics between the two groups of patients, and to evaluate the differences in the prognosis of two groups of patients. [Results:] There were 533 patients (63.15%) underwent M and 311 patients (36.85%) underwent BCS. Patients with younger age, smaller tumor size, negative lymph node, and loss of HER2 expression (HER2-0) were more tend to BCS group compared to M group. Median follow-up time was 72 months. Multivariate COX analysis showed that the OS of M group was lower than that of BCS group (HR=2.02, 95% CI: 1.04-3.91, P=0.038), but there was no significant difference in DFS between the two groups (HR=1.42, 95% CI: 0.94-2.15, P=0.100). After propensity score matching for factors such as T stage, N stage and age, the results showed that there was no significant difference in OS (P=0.114) and DFS (P=0.124) between BCS and M groups. [Conclusions:] Among patients with stage Ⅰ-Ⅲ TNBC, patients with younger age, smaller tumor, negative lymph node, and HER2-0 were more likely to choose BCS. After propensity score matching for relevant clinicopathological parameters, the results indicated that there was no significant difference in OS and DFS of the TNBC patients undergoing BCS or M surgery.
