Brief Summary:

There are limited data from retrospective studies regarding whether short-term and long-term outcomes after laparoscopic or robot-assisted radical colectomy (minimally invasive surgery) are equivalent to those after open abdominal radical colectomy (open surgery) among patients with early and medium-stage colorectal cancer.

This trial is a multicenter,prospective, randomized trial evaluating short-term and survival outcomes concerning minimally invasive surgery and open surgery for colorectal cancer.

Laparoscopy Procedure: minimally invasive surgery Not Applicable

Detailed Description:

Radical colectomy and proctectomy with regional lymphadenectomy remain the standard recommendation for patients with early and medium-stage colorectal cancer. Current guidelines from the National Comprehensive Cancer Network indicate that either laparotomy (open surgery) or laparoscopy (minimally invasive surgery performed with either conventional or robotic techniques) is an acceptable approach to radical resection in patients with early- and medium stage (I to III) colorectal cancer. These recommendations have led to widespread use of a minimally invasive approach for radical resection, although there is a paucity of adequately powered, prospective, randomized trials evaluating short term and survival outcomes.

Retrospective studies involving patients with early and medium-stage colorectal cancer have shown that laparoscopic resection is associated with less intraoperative blood loss, a shorter length of hospital stay, and a lower risk of postoperative complications than open abdominal radical resection. Similarly, the minimally invasive approach has not been associated with lower 5-year rates of disease-free survival or overall survival than the open approach. In addition, retrospective studies have shown that recurrence rates and survival rates do not differ significantly between the two approaches.

The investigators hypothesized that minimally invasive surgery was not inferior or superior to open radical resection in terms of short-term and long-term outcome. In the present trial, the Laparoscopic Resection and Laparotomy for Colorectal Cancer (LRLCC) Trial, the investigators tested this hypothesis by prospectively assigning patients to minimally invasive (conventional laparoscopic or robotic) or open abdominal radical surgery and comparing the short-term outcome, the rate of recurrence, and the overall survival rate between the two groups.

Arm Intervention/treatment
Experimental: minimally invasive surgery

Patients were randomized to undergo minimally invasive radical resection (endoscopic surgery or robotic assisted surgery). Each participating site required accreditation by the trial management committee to ensure proper surgical technique during minimally invasive surgery.

Patients were eligible if they had colorectal adenocarcinoma; had a disease stage of I (T1,T2), IIABC (T3-T4ab) or IIIABC (TanyN1-2) according to the staging system of NCCN; and had an Eastern Cooperative Oncology Group (ECOG) performance-status score of 0 or 1 (on a 5-point scale, with higher values indicating greater disability).

Procedure: minimally invasive surgery
Each participating site required accreditation by the trial management committee to ensure proper surgical technique during minimally invasive surgery. No individual surgeons performed only the open approach or only the minimally invasive approach. The committee members reviewed the patients' outcomes and the videos to ensure the adequacy of the surgeon's technique.

No Intervention: open surgery

Patients were randomized to undergo open radical resection (laparotomy). Each participating site required accreditation by the trial management committee to ensure proper surgical technique during minimally invasive surgery.

Patients were eligible if they had colorectal adenocarcinoma; had a disease stage of I (T1,T2), IIABC (T3-T4ab) or IIIABC (TanyN1-2) according to the staging system of NCCN; and had an Eastern Cooperative Oncology Group (ECOG) performance-status score of 0 or 1 (on a 5-point scale, with higher values indicating greater disability).

Exclusion criteria included a history of abdominal or pelvic radiotherapy, or evidence of metastatic disease on positron-emission tomography-computed tomography, magnetic resonance imaging, or computed tomography.




Primary Outcome Measures :
  1. complications [ Time Frame: through hospital stay, an average of two weeks ]
    complications includes intraoperative and postoperative complications, such as huge blood loss, anastomotic fistula, abdominal infection and septic shock.

  2. disease free survival [ Time Frame: From date of randomization until the date of first documented progression, assessed up to 70 months ]
    Disease-free survival (DFS) was defined as the interval between the date of surgical resection and diagnosis of recurrence or the most recent follow-up date.

  3. overall survival [ Time Frame: From date of randomization until the date of death from any cause, assessed up to 70 months. ]
    Overall survival (OS) was measured from the date of hepatectomy to death with or without HCC recurrence or the end of this study period.
