Brief Title: Transanal Versus Laparoscopic Total Mesorectal Excision For Rectal Cancer

Official Title: Transanal Versus Laparoscopic Total Mesorectal Excision for Mid And Low Rectal Cancer in China (TLTME): a Single-center Randomized Clinical Trial

Study ID: NCT03359616

Study Description

Brief Summary: Total mesorectal excision (TME) has been prevailingly accepted as a crucial surgical intervention within the latest oncological therapeutic regime for mid-low rectal cancer. However, surgical dissection under the restricted pelvic anatomical structure, added by obesity and many other general factors, remains challenging for classical open and laparoscopic patterns, particularly in male cases. The introduction of transanal total mesorectal excision (TaTME) offers an optimal pattern for the surgical resection of mid-low rectal cancer, circumventing the conventional anatomical limits while bringing forward considerable advantages by direct dissection. Noteworthy, the surgical techniques of TaTME is initially established, with the mortality/morbidity and the oncological safety unverified. The studies that focus on the comparison between TaTME and laparoscopic TME (LaTME) remain sparse. Therefore, the features of TaTME, both in short and long terms, await further consolidation by clinical trials. Herein, this single centered, interventional study protocol is established to collect initial clinical data on both the safety and efficacy of the TaTME in comparison with LaTME in East Chinese patients with mid-low rectal cancer.

Detailed Description: Background: Transanal total mesorectal excision (TaTME) is increasingly accepted as one of the alternative patterns for the resectable rectal cancer worldwide since its first appearance. For mid-low rectal cancer, TaTME features superior viewpoints and direct access to mobilize the primary lesion without the pelvic anatomic limits. Therefore, the matured TaTME technique could deliver satisfactory clinic outcomes in both surgical and oncological senses. However, the studies that designed to compare the feasibility and repeatability of TaTME with conventional laparoscopic total mesorectal excision (LaTME) remain sparse and limited. Study Objective: Evaluation of short-term mortality and morbidity, long term overall survival and disease-free survival as well as quality of life in rectal cancer patients in East China. Study Design: This study is a prospective, single-center, randomized clinical trial with a central monitored electronic data processing system. Corresponding randomization, data collection and comparative analysis will be conducted based on the research group discussion. According to the non-inferiority principle, the power is 80% and the α is 0.05 with 10% margin delta (δ). Total patients will be 258, with 129 in each group given 10% lost in follow-up. Study Endpoints: The primary outcomes measures will be the Disease-free survival (3-years). The secondary outcomes measures will be overall survival (3-years), mesorectal completeness (the quality of the TME specimen, complete, near complete, incomplete), positive circumferential resection margin (CRM), number of retrieved lymph nodes, morbidity rate, mortality rate.
