The association between the serum levels of cancer antigen 125 (CA125; also termed MUC16) and the prognosis of patients with hepatocellular carcinoma (HCC) has not been widely reported to date. The aim of the present study was to determine the association between preoperative serum CA125 levels and prognosis of patients with hepatitis B virus (HBV)‑related HCC after hepatectomy. The study included 306 patients with HBV‑related HCC who underwent liver resection and were classified into four subgroups based on their baseline CA125 and α‑fetoprotein (AFP) levels. The perioperative clinical data were compared and analyzed. Kaplan‑Meier and Cox regression analyses were performed to determine the associations between patient clinicopathological characteristics and survival. The results revealed that the median follow‑up time was 35 months. Patients with low preoperative serum CA125 levels presented with improved 3‑year disease‑free survival (DFS) (79.3 vs. 75.7%; P=0.278) and overall survival (OS) (84.4 vs. 77.1%; P=0.001) rates compared with those among patients with high preoperative serum CA125 levels. High preoperative serum CA125 levels were a risk factor associated with short DFS and OS rates in all patients. In patients with baseline AFP levels >100 ng/ml, low preoperative serum CA125 levels were significantly associated with prolonged DFS and OS rates (log‑rank test P=0.002 and P=0.005, respectively). In patients with AFP levels ≤100 ng/ml, no significant differences were observed in DFS or OS rates between the high and low preoperative serum CA125 groups. Patients with high preoperative serum CA125 and AFP levels exhibited the worst prognosis (low DFS and OS rates). In conclusion, high baseline CA125 levels may be associated with a poor prognosis in patients with HBV‑related HCC.
