What the trial is, and whether it could suit you
The main objective of this study was to evaluate the effect of surgical margin width on the prognosis of patients with hepatic oligometastasis of colorectal cancer by statistical 1-year intrahepatic recurrence-free survival rate (ihRFSrate). The secondary objective of the study was to evaluate the effect of surgical margin width on long-term survival and total recurrence of colorectal cancer in patients with hepatohepatic metastasis by statistical overall survival time (OS) and relapse-free survival time (RFS), and to evaluate the safety of wide margin surgery compared with narrow margin surgery in patients with Cromitis during perioperative period.
This was a single-center, prospective, randomized controlled clinical study to evaluate the effects of surgical margin width on 1-year intrahepatic relapse-free survival, relapse-free survival time, overall survival time, and perioperative s
