BACKGROUND: The effectiveness of postoperative adjuvant transarterial chemoembolization (TACE) on survival and recurrence in tumor-node-metastasis (TNM) stage I intrahepatic cholangiocarcinoma (ICC) after radical resection remains unclear. This study aimed to compare overall survival (OS) and recurrence-free survival (RFS) in TNM stage I ICC patients with and without postoperative TACE. METHODS: A retrospective cohort study was conducted on TNM stage I ICC patients who had undergone R0 resections with curative intent in Shanghai Eastern Hepatobiliary Surgery Hospital from January 2012 to December 2016. A total of 269 patients were divided into two groups: (I) 35 patients who received postoperative TACE and (II) 234 patients no TACE. Staging was performed according to the 8th edition of American Joint Committee on Cancer (AJCC) TNM staging system. The tumor-related RFS and OS were estimated by the Kaplan-Meier method. Cox proportional regression model was employed to evaluate the prognosis between the two groups. RESULTS: In all patients, the median OS was 66.8 months. After R0 resection, adjuvant TACE could not improve the survival of TNM stage I patients, and the OS of the TACE group was not better than that of the non-TACE group (P=0.7070). In addition, in the TACE group, the recurrence rate of TNM stage I ICC patients was statistically significantly higher than that of the non-TACE group (P=0.0328). Multivariable analysis revealed that adjuvant TACE was an independent pred...
