They were divided into the long duration group (n = 57) and short duration group (n = 28) based on postoperative medication duration. Recurrence-free survival (RFS) and overall survival (OS) were analyzed and compared between the cohorts.Results: No significant difference in RFS or OS was found between the two groups [RFS: hazard ratio (HR) = 0.486; 95% confidence interval (CI), 0.229– 1.034, P = 0.061; OS: HR = 0.377; 95% CI, 0.119– 1.196, P = 0.098]. Patients without major pathologic response (MPR) in the long duration group had better RFS and OS results compared to those in the short duration group (RFS: HR = 0.242; 95% CI, 0.092– 0.634, P = 0.004; OS: HR = 0.264; 95% CI, 0.079– 0.882, P = 0.031). No significant difference was detected in RFS or OS between the two groups in patients with MPR (RFS: HR = 1.250; 95% CI, 0.373– 4.183, P = 0.718; OS: HR = 7.389; 95% CI, 0.147– 372.4, P = 0.317). After propensity score matching, 25 pairs of patients were selected and the results remained consistent.Conclusion: At least 6 months of adjuvant therapy may be beneficial for patients without MPR after conversion surgery. However, in patients with MPR, the effect of adjuvant therapy remains unclear. Further studies are needed to confirm the optimal duration of adjuvant therapy.Keywords: unresectable, hepatocellular carcinoma, conversion therapy, adjuvant therapy, recurrence-free survival, overall survival
