Abstract

Background: Curative operation is the practical and primary therapy for masses of breast cancers. In contrast, the correlation between the time interval from breast cancer diagnosis to curative surgery and survival is still uncertain.

Methods: An electronic literature search was conducted on PubMed/Medline and EMBASE (between Jan 2000 and Jan 2020). Primary endpoints were overall survival (OS) or Disease-Free Survival (DFS). The HR with 95% confidence intervals were calculated using a random-effects or fixed-effects model.

Results: The combined HR for OS was 1. 10 (95% CI 1. 08-1. 11; P=0. 000) by fixed-effects model, no statistically significant heterogeneity was found (P=1. 000; I2=0%), and this difference was statistically significant (Z=11. 99; P=0. 000).

Conclusion: This meta-analysis showed a significant adverse association between more prolonged time to surgery (TTS) and lower overall survival in patients with breast cancer. It is reasonable to minimize that interval between diagnosis and curative surgery.
