Abstract:Objective To investigate the recurrence and related factors of esophageal cancer after endoscopic submucosal dissection (ESD).Methods 100 patients with ESD for esophageal cancer from January 2018 to October 2020 were selected as the study subjects, followed up by telephone or outpatient review for 1-year postoperative recurrence, Logistic regression equations were used to analyze the factors influencing postoperative recurrence, and R software was used to establish a column line graph model for predicting postoperative recurrence after ESD for esophageal cancer.Results One-year follow-up after operation, 6 cases of 100 patients who underwent ESD for esophageal cancer were lost to follow-up, and the recurrence rate was 10.64%; The risk factors of recurrence of esophageal cancer after ESD were lesion diameter ≥ 3.11 cm, SM1 cancer, lesion endoscopy mixed type, intraoperative severe adhesion, preoperative inability to eat and postoperative vascular tumor thrombus (P < 0.05); The initial C-index of the nomogram model was 0.876, and the calibration curve showed that the nomogram model had good discrimination and consistency.Conclusion Based on six high-risk factors, including lesion diameter ≥ 3.11 cm, SM1 cancer, mixed type of lesion under endoscopy, severe intraoperative adhesion, preoperative inability to eat and postoperative vascular tumor thrombus, a nomograph model is constructed to predict the recurrence risk of esophageal cancer after ESD, which can accurately identify the recurrence risk after ESD and guide clinical diagnosis and treatment.
