Single-center Experience on Actual Mid-Term (≥5 Years) and Long-Term (≥10 Years) Survival Outcome in Patients with Hepatocellular Carcinoma after Curative Hepatectomy

Analysis for actual mid-term (>= 5 years) and long-term (>= 10 years) survivors with hepatocellular carcinoma (HCC) following curative hepatectomy are rarely reported in the literature. This retrospective study aims to study the mid- and long-term survival outcome and associated prognostic factors following curative hepatectomy for HCC in a tertiary referral center. The clinical data of 325 patients who underwent curative hepatectomy for HCC were reviewed. They were stratified into 3 groups for comparison (Group 1, overall survival <5 years; Group 2, overall survival >= 5, and <10 years; Group 3, overall survival >= 10 years). Favorable independent prognostic factors for mid- and long-term survival were analyzed. A bimodal distribution of actual survival outcome was observed, with short-term (<5 years) survival of 52.7% (n = 171), mid-term survival of 18.1% (n = 59), and long-term survival of 29.2% (n = 95). Absence of microvascular invasion (OR 3.690, 95% CI: 1.562-8.695) was independent good prognostic factor for mid-term survival. Regarding long-term overall survival, young age (OR 1.050, 95% CI: 0.920-0.986), ASA grade <= 2 (OR 3.746, 95% CI: 1.325-10.587), high albumin level (OR 1.008, 95% CI: 0.920-0.986), solitary tumor (OR 3.289, 95% CI: 1.149-7.625) and absence of microvascular invasion (OR 4.926, 95% CI: 2.192-11.111) were independent good prognostic factors. Curative hepatectomy results in bimodal actual survival outcome with favorable long-term survival rate of 29.2%. Favorable independent prognostic factors (age, ASA grade, albumin level, tumor number, and microvascular invasion) are identified for overall survival.
