Abstract

BackgroundThere is currently no standard adjuvant treatment proven to prevent hepatocellular carcinoma (HCC) recurrence. Recent studies suggest that postoperative adjuvant transarterial chemoembolization (PA-TACE) is beneficial for patients at high risk of tumor recurrence. However, it is difficult to select the patients. The present study aimed to develop an easy-to-use score to identify these patients. MethodsA total of 4530 patients undergoing liver resection were recruited. Independent risk factors were identified by Cox regression model in the training cohort and the Primary liver cancer big data transarterial chemoembolization (PDTE) scoring system was established. ResultsThe scoring system was composed of ten risk factors including alpha-fetoprotein (AFP), albumin-bilirubin (ALBI) grade, operative bleeding loss, resection margin, tumor capsular, satellite nodules, tumor size and number, and microvascular and macrovascular invasion. Using 5 points as risk stratification, the patients with PA-TACE had higher recurrence-free survival (RFS) compared with non-TACE in > 5 points group (P < 0.001), whereas PA-TACE patients had lower RFS compared with non-TACE in ≤ 5 points group (P = 0.013). In the training and validation cohorts, the C-indexes of PDTE scoring system were 0.714 [standard errors (SE) = 0.010] and 0.716 (SE = 0.018), respectively. ConclusionsThe model is a simple tool to identify PA-TACE for HCC patients after liver resection with a favorable performance. Patients with > 5 points may benefit from PA-TACE.
