ABSTRACT
Objective:To evaluate a nano-carbon lymphatic tracing method for patients with rectal cancer after neoadjuvant radiotherapy and chemotherapy .Method:Retrospective analysis was made on 88 patients of rectal cancer undergoing neoadjuvant chemoradiation at the Department of General Surgery, He′nan Cancer Hospital from Jan 2016 to May 2020.According to whether nano-carbon lymph node was used or not, patients were divided into nanocarbon tracer group (study group) and non-nanocarbon tracer group (control group).Results:There was statistically significant in the number of havested lymph nodes between the two groups [15(11-19) vs.9(5-12), Z=5.227, P<0.001], There was no statistically significant in the number of positive lymph nodes between the two groups [0(0-0.25) vs.0(0-1), Z=1.199, P=0.231]. There were significant differences in the ratio of patients with less than 7 lymph nodes(0/34 vs.18/54, χ 2=14.248, P<0.001) and patients with less than 10 lymph nodes (4/34 vs.29/54, χ 2=15.657, P<0.001). Conclusions:The injection of nanocarbon after neoadjuvant chemoradiotherapy can increase the number of harvested postoperative lymph nodes and the ratio of patients with lymph nodes ≥7 and ≥10, which is more beneficial for prediction of the prognosis of patients.
