Aims: To compare the long-term prognosis of younger and elderly patients with combined hepatocellular-cholangiocarcinoma (CHC) who underwent curative resection between 1993 and 2014 at our center.
Methods: Two hundred and thirteen patients who underwent liver resection for CHC were enrolled in our study. The overall survival (OS) and disease-free survival (DFS) of elderly patients (age≥60, n=52) and younger patients (age<60, n=161) were compared by multivariate analysis and propensity score matching (PSM) analysis.
Results: Among the 213 CHC patients, the elderly patients had a higher rate of worse Child-Pugh grade (P=0.027), abnormal serum albumin (P<0.001) and lymphoid metastases (P=0.024). The proportion of HBV-positive CHC patients (74.6%, 159/213) was much higher than that observed in healthy cohorts. Younger patients had a higher rate of hepatitis B virus (HBV) infection compared to older patients (83.9% vs 46.2%, P<0.001). OS and DFS of the elderly and younger patients before and after propensity score matching were comparable.
Conclusion: Elderly and younger patients who underwent liver resection for CHC have comparable long-term OS and DFS.
