A systematic review and meta-analysis of surgery delays and survival in breast, lung and colon cancers: Implication for surgical triage during the COVID-19 pandemic

Am J Surg. 2021 Aug;222(2):311-318. doi: 10.1016/j.amjsurg.2020.12.015. Epub 2020 Dec 8.

Abstract

Background: Thousands of cancer surgeries were delayed during the peak of the COVID-19 pandemic. This study examines if surgical delays impact survival for breast, lung and colon cancers.

Methods: PubMed/MEDLINE, EMBASE, Cochrane Library and Web of Science were searched. Articles evaluating the relationship between delays in surgery and overall survival (OS), disease-free survival (DFS) or cancer-specific survival (CSS) were included.

Results: Of the 14,422 articles screened, 25 were included in the review and 18 (totaling 2,533,355 patients) were pooled for meta-analyses. Delaying surgery for 12 weeks may decrease OS in breast (HR 1.46, 95%CI 1.28-1.65), lung (HR 1.04, 95%CI 1.02-1.06) and colon (HR 1.24, 95%CI 1.12-1.38) cancers. When breast cancers were analyzed by stage, OS was decreased in stages I (HR 1.27, 95%CI 1.16-1.40) and II (HR 1.13, 95%CI 1.02-1.24) but not in stage III (HR 1.20, 95%CI 0.94-1.53).

Conclusion: Delaying breast, lung and colon cancer surgeries during the COVID-19 pandemic may decrease survival.
