Rutkowski A, et al. - A previous study demonstrated that application of gentamicin-collagen implant (GCI) into the pelvic cavity after total mesorectal excision (TME) reduced the incidence of distant metastases, so researchers conducted a confirmatory study analyzing data of patients with rectal cancer. Eligibility criteria included adenocarcinoma of the rectum, preoperative short-term radiotherapy (5 × 5 Gy), and WHO performance score 0–1. The data showed the rate of distant metastases in patients after radical rectal cancer resection was significantly lessened after GCI application to the pelvic cavity.
