Circumferential Resection Margin as a Prognostic Marker in the Modern Multidisciplinary Management of Rectal Cancer

Abstract

Circumferential resection margin is an important measurement in rectal cancer pathology, but the correlation to local recurrence is much less than previously stated, probably because of oncological treatment and surgery that respects the mesorectal fascia and, when required, en bloc resections. Circumferential resection margin should not be used as a prognostic marker in the modern multidisciplinary management of rectal cancer.
