Investigating the prognostic value of lateral mesorectum using preoperative high-resolution MRI in patients with rectal cancer.

ABSTRACT:

Background

To explore the lateral mesorectum structures and develop a nomogram model for predicting the prognosis of rectal cancer (RC) patients using preoperative high-resolution magnetic resonance imaging (MRI).

Methods

Patients who underwent radical resection of RC in our hospital from January 2017 to December 2018 were retrospectively analyzed. Imaging data and postoperative 3-year prognosis data of patients were collected. The lateral mesorectum was observed, and related parameters were investigated: lateral interruption of the mesorectal fascia (LI-MRF), type of the middle rectal artery (MRA), and the maximum diameter of the MRA. The impact of lateral mesorectum parameters on prognosis was determined using Cox analysis and Kaplan-Meier (KM) survival curves. A nomogram
