Changes in Reoperation After Publication of Consensus Guidelines on Margins for Breast-Conserving Surgery. A Systematic Review and Meta-analysis

Abstract

The 2014 publication of the Society of Surgical Oncology-American Society for Radiation Oncology (SSO-ASTRO) Consensus Guideline on Margins for Breast-Conserving Surgery recommended a negative margin definition of no ink on tumor. Adoption of this guideline would represent a major change in surgical practice that could lower the rates of reoperation.

The objective of this paper was to assess changes in reoperation rates after publication of the SSO-ASTRO guideline.

A systematic search of Embase, PREMEDLINE, Evidence-Based Medicine Reviews, Scopus, and Web of Science for biomedical literature published from January 2014 to July 2019 was performed. This search was supplemented by web searches and manual searching of conference abstracts.
