Abstract
ObjectiveTo evaluate the survival outcomes of combined liver resection (LR) and radiofrequency ablation (RFA) on multi-focal hepatocellular carcinoma (HCC) in patients with Barcelona clinic liver cancer (BCLC) stage B.MethodsA total of 210 cases of HCC were included in this study. In 42 cases, patients were treated with combination therapy using LR and RFA (LRCRFA). In 84 cases, patients underwent transarterial chemoembolization (TACE), and in another 84 cases, patients underwent LR; both the TACE and LR groups served as controls. It both categorized as BCLC stage B for LRCRFA and TACE groups but as BCLC stage A for LR group.ResultsThe overall survival (OS) rate of the LRCRFA group was significantly higher than that of the TACE group (P<0.001) but was not significantly different when compared with the LR group (P=0.544). The disease-free survival (DFS) rate of the LRCRFA group was significantly lower than that of the LR group (P=0.029). Patients with ≤4 tumors or those with ≤5 tumors no larger than 6 cm in diameter experienced better long-term outcomes than other patients in the same LRCRFA group. The OS rates and DFS rates were not significantly different from those of patients in the LR group (P>0.05). Having more than 2 existing tumors was an independent risk factor for OS rate.ConclusionCombination therapy using LR and RFA can more effectively improve the prognosis of these patients than TACE. Patients with BCLC stage B HCC with ≤4 tumors or ≤5 tumors smaller than 6 cm in diameter are the ideal candidates for the application of LRCRFA.
