Oncological results in rectal cancer patients with a subcentimetre distal margin after laparoscopic-assisted sphincter-preserving surgery.

ABSTRACT:

Background

Distal resection margin (DRM) is closely associated with sphincter-preserving surgery and oncological safety for patients with mid-low rectal cancers. However, the optimal DRM has not been determined.

Methods

Data of 378 rectal cancer patients who underwent laparoscopic-assisted sphincter-preserving surgery from 2009 to 2015 were retrospectively analysed. Patients were divided into two groups based on DRM: ≤1 cm (n = 74) and >1 cm (n = 304). To minimize the differences between the two groups, propensity-score matching on baseline features was performed.

Results

Before propensity-score matching, no significant differences in 5-year disease-free survival (DFS) (92.8% versus 81.3%, P = 0.128) and 5-year overall survival (OS) (83.7% versus 82.2%, P = 0.892) wer
