An investigation into tumor regression grade as a parameter for locally advanced rectal cancer and 5-year overall survival rate.

Purpose: The standard treatment for locally advanced rectal cancer (LARC) is neoadjuvant chemoradiation (nCRT) followed by surgery. Several parameters are associated with patient survival in LARC. One of these parameters is tumor regression grade (TRG); however, the significance of TRG remains controversial.

Urogenital dysfunction after laparoscopic surgery for rectal or sigmoid colon cancer.

Background/objective: Urogenital dysfunction is a common complication after surgery for sigmoid colon or rectal cancers and may result from various causes. Herein, we evaluated urogenital dysfunction and the associated factors after laparoscopic surgery at different follow-up times.

Methods: We conducted a prospective study on 91 patients who were diagnosed with sigmoid colon and rectal cancers and underwent laparoscopic surgery during 2014-2016.
