Comparison of curative efficacy and prognosis between fluorescent laparoscopic and conventional laparoscopic radical resection of colorectal cancer / 肿瘤研究与临床

ABSTRACT

Objective:To compare the efficacy and prognosis between fluorescent laparoscopic and conventional laparoscopic radical resection of colorectal cancer.Methods:A total of 114 colorectal cancer patients in Bishan District People's Hospital of Chongqing from June 2019 to January 2021 were selected as the research objects, and they were divided into two groups according to the diagnosis and treatment time. Forty-four patients receiving treatment from June 2019 to February 2020 were enrolled as group A, and 70 patients receiving treatment from March 2020 to January 2021 were set as group B. Patients in group A received fluorescent laparoscopic radical resection of colorectal cancer, and patients in group B received conventional laparoscopic radical resection of colorectal cancer. The operation time, intraoperative blood loss, metastatic lymph node clearance rate, clinical efficacy (the overall response rate was calculated as complete remission + partial remission), postoperative complication rate and recurrence rate within 1 year were compared between the two groups.Results:The clearance rate of metastatic lymph nodes was 86.95% (40/46) in group A, which was higher than 72.22% (52/72) in group B, and the difference was statistically significant ( χ2 = 3.55, P = 0.049). There were no statistical differences in operation time and intraoperative blood loss between the two groups (all P > 0.05). The overall response rate was 86.36% (38/44) in group A, which was higher than 74.28% (52/70) in group B, and the difference was statistically significant ( χ2 = 5.03, P = 0.024). The incidence of complications in group A was 9.09% (4/44), which was not significantly different from that in group B (11.42%,8/70) ( χ2 = 0.16, P = 0.692). The recurrence rate within 1 year of group A was 11.36% (5/44), which was lower than that of group B (24.42%, 15/70), but the difference was not statistically significant ( χ2 = 1.89, P = 0.169). Conclusions:Compared with conventional laparoscopy, fluorescent laparoscopic radical resection of colorectal cancer has better clinical efficacy, higher clearance rate of metastatic lymph nodes, and does not increase the incidence of postoperative metastasis and complications.
