Effects of magnetic resonance imaging (MRI)-detected extramural vascular invasion (mrEMVI) and tumor deposits (TDs) on distant metastasis and long-term survival after surgery for stage III rectal cancer: a retrospective study grouped based on the relationship between the bottom of the tumor and peritoneal reflection.

ABSTRACT:

Background

To evaluate the effect of magnetic resonance imaging (MRI)-detected extramural vascular invasion (mrEMVI) and tumor deposits (TDs) on distant metastasis and long-term survival after surgery for stage III rectal cancer based on the relationship between the bottom of the tumor and peritoneal reflection.

Methods

A retrospective study was performed on 694 patients who underwent radical resection for rectal cancer at the Harbin Medical University Tumor Hospital from October 2016 to October 2021. According to the surgical records, a new group was established based on the relationship between the lower end of the tumor and peritoneal reflection. On the peritoneal reflection group: the tumors are all located on the peritoneal reflection. Across the peritoneal reflection g
