Key clinical point: Women with early-stage invasive breast cancer (BC) who underwent breast-conserving surgery with radiotherapy (BCS) had better overall survival (OS) than those who underwent mastectomy.
Major finding: Compared with mastectomy, BCS was associated with improved OS in the overall population of patients with early-stage invasive BC (relative risk [RR] 0.64; 95% CI 0.55-0.74), with stronger effects observed in women followed-up for <10 years (RR 0.54; 95% CI 0.46-0.64).
Study details : Findings are from a meta-analysis of 30 studies including 1,802,128 women with early-stage invasive BC, of which 1,075,563 and 744,565 patients underwent BCS and mastectomy, respectively, and were followed-up for 4-20 years.
Disclosures: This study did not receive any external funding. Dr. Chatterjee declared serving as a consultant for 3M and Royal.
