A randomized controlled trial of the conventional technique versus the no-touch isolation technique for primary tumor resection in patients with colorectal cancer: Japan clinical oncology group study JCOG1006

摘要

A randomized controlled trial is currently being conducted in Japan to demonstrate the superiority of the no-touch isolation technique over the conventional technique for patients with potentially curative colon and rectosigmoid cancer. The conventional technique procedure gives first priority to mobilization of the tumor-bearing segment of the colon, which is followed by central vascular ligation and ligation of other vasculature. Conversely, the no-touch isolation technique gives first priority to central vascular ligation, which is followed by mobilization of the tumorbearing segment of the colon. A total of 850 patients will be enrolled in this trial. The primary endpoint is disease-free survival. Secondary endpoints are overall survival, relapse-free survival, liver metastasis-free survival, mode of recurrence, surgical morbidity, adverse events due to postoperative chemotherapy, serious adverse events and short-term clinical outcomes.
