Abstract:
Objective:To evaluate the value of lymph node regional sorting in radical colorectal cancer surgery.Methods:Between Jan 2021 and Mar 2022, A total of 307 colorectal cancer patients undergoing radical surgery at the Tianjin Medical University General Hospital were retrospectively included and assigned to either the lymph node regional sorting group (123) or no-sorting group (184) according to the lymph node examination methods.Results:There was a significant difference between the two groups in the number of total lymph nodes and negative lymph nodes (26.74±13.08 vs. 16.80±4.87, t=9.381, P<0.001; 25.65±13.25 vs. 16.04±4.87, t=8.979, P<0.001). The number of positive lymph nodes of lymph node regional sorting group increased compared with no-sorting group (1.09±2.28 vs. 0.76±1.34, t=1.589, P=0.113). A total of 52 cases in the lymph node regional sorting group showed metastasis, of which 10 showed lymph node skip metastases. There was no significant difference in tumor location and TNM stage between skip and non-skip lymph node metastasis patients. Conclusions:The lymph node regional sorting increase the number of examined lymph nodes. The method can determine the positive lymph node distribution and ensure the accuracy of staging.
