Spots Global Cancer Trial Database for Safety and Efficacy of Reduced-port Laparoscopic Surgery for Patients Of Colon and Upper Rectal Cancer

Study Description

Brief Summary: Colorectal cancer is the third most common malignant tumor. Radical resection is the mainstay of treatments for non-metastatic colorectal cancer. In case of traditional laparoscopic surgery, inexperienced assistants are likely to cause side injuries and interfere surgeon due to limited operating space. Reduced-port laparoscopic surgery has only 3 ports for surgeon and observer, and the surgeon completes the surgery independently, which increases the difficulty of the operation. However, reduced-port laparoscopy has some potential advantages and applications. Reduced-port laparoscopic surgery avoids the prolongation of the operation time and parainjury caused by inexperienced assistant. Reduced-port laparoscopy reduces some surgical incisions, resulting in less pain and faster recovery. Reduced-port laparoscopy also reduces the consumables, human resources and medical expenses. This study aims to evaluate the curative effect and safety of reduced-port laparoscopic surgery versus conventional laparoscopic surgery for resectable colorectal cancer.

Detailed Description: Colorectal cancer is the third most common malignant tumor. In 2020, there were nearly 1.9 million new cases worldwide, accounting for about 10% of all new malignant tumors, and the related death exceeded 900,000. In recent years, the incidence of colorectal cancer in our country has been rising rapidly year by year, with more than 400,000 new cases each year, leading China to the largest number of colorectal cancer cases in the world. For resectable non-metastatic colorectal cancer, radical surgical resection is the mainstay of treatments. Compared with the open surgery, the laparoscopic colorectal cancer resection has smaller wounds, faster postoperative recovery, and shorter hospital stay. The 10-year results of the COLOR trial showed similar DFS, OS, and recurrence rates between open and laparoscopic surgery for colon cancer. In another trial (COST study), 872 patients with colon cancer were randomly assigned to open surgery or laparoscopic-assisted colectomy for curative colon cancer. After a median follow-up of 7 years, the 5-year recurrence rates and the 5-year OS rates were similar. Traditional laparoscopic colorectal cancer resection can be carried out smoothly by close cooperation between the surgeon and the assistant. However, inexperienced assistants are likely to cause parainjuries due to the opposite field of the view and the narrow operating space. In recent years, single-port laparoscopy gradually goes into service. However, it is easy to cause instrument conflicts, straight-line viewing angles, and lack of traction. Therefore, single-port surgery is extremely unergonomic and difficult for the surgeon. Reduced-port laparoscopic surgery has been selectively used in some colon cancer anticipants. Reduced-port laparoscopic surgery reduces or completely eliminates the assistant's operating ports, and the surgeon mainly relies on himself/herself to complete the exposure of the operative field. However, reduced-port laparoscopy has some potential advantages and applications. Reduced-port laparoscopic surgery is completed by the left and right hands of the surgeon, which is easier to coordinate, avoiding the prolongation of the operation time or even concomitant injury caused by the poor cooperation of the inexperienced assistant and the surgeon. Reduced-port laparoscopy reduces some surgical incisions, and extreme minimally invasive may result in less pain and faster recovery. From an economic point of view, the reduced-port laparoscopy reduces some surgical consumables and human resouce, leading to reduced cost of surgery. In order to further explore the application of reduced-port laparoscopic surgery in patients with resectable colorectal cancer, the center plans to carry out a clinical study of 'reduced-port laparoscopic surgery versus traditional laparoscopic surgery for resectable colorectal cancer', aiming to evaluate the complications associated with perioperative surgery, R0 resection rate, 3-year disease-free survival rate, and 3-year overall survival rate.
