CABG using BITA grafts showed no advantages in midterm outcome among hemodialysis patients; however, there were no adverse effects on perioperative morbidity or death. For hemodialysis patients with limited available conduits, BITA may be an important option for multivessel revascularization.
Aim: Although radiofrequency ablation (RFA) is an effective local treatment of hepatocellular carcinoma (HCC), local recurrence is relatively frequent. We aimed to elucidate the validity of salvage liver resection for recurrent HCC after RFA.Methods: Patients who underwent liver resection for recurrent HCC after RFA (LR after RFA) and those who underwent second liver resection for recurrent HCC (second LR) were included. The short-term outcomes were compared between the two groups. The survival rates between the two groups were compared after propensity-score matching to adjust for the variables, including patient background, liver function, and tumor status.Results: Major resection was frequently carried out in the LR after RFA group, but there was no significant difference both in operative data and complication rate between LR after RFA (n = 54) and second LR (n = 266) groups. After a median followup period of 1.8 years (range, 0.2-10.5), the median overall survival was 4.4 years (95% confidence interval [CI], 2.2not applicable) and 5.6 years (95% CI, 4.5-7.3; P = 0.023) in the LR after RFA group (n = 54) and second LR group (n = 54), respectively, and recurrence-free survival was 1.3 years (0.4-2.2) and 1.2 years (0.5-1.8, P = 0.469), respectively. The only independent factor for overall survival of the LR after RFA group was local recurrence (hazard ratio, 2.73; 1.06-9.00).
Conclusions: Salvage liver resection of recurrent HCC afterRFA could be recommended due to the safety of the procedure, especially in patients without local tumor progression after RFA.
Background
Despite curative resection, hepatocellular carcinoma (HCC) has a high probability of recurrence. We validated the potential role of liver resection (LR) for recurrent HCC.
Methods
Patients with intrahepatic recurrence with up to three lesions were included. We compared survival times of patients undergoing their first LR to those of patients undergoing repeated LR. Then, survival times of the patients who had undergone LR and transcatheter chemoembolization (TACE) for recurrent HCC after propensity score matching were compared.
Results
After a median follow‐up period of 3.1 years (range, 0.2–16.3), median overall survival times were 6.5 years (95% CI 6.0–7.0), 5.7 years (5.2–6.2), and 5.1 years (4.9–7.3) for the first LR (n = 1234), second LR (n = 273), and third LR (n = 90) groups, respectively. Severe complications frequently occurred in the first LR group (p = 0.059). Operative times were significantly longer for the third LR group (p = 0.012). After the first recurrence, median survival times after one‐to‐one pair matching were 5.7 years (95% CI 4.5–6.5) and 3.1 years (2.1–3.8) for the second LR group (n = 146) and TACE group (n = 146), respectively (p < 0.001). The median survival time of the third LR group (n = 41) (6.2 years; 95% CI 3.7–NA) was also longer than that of TACE group (n = 41) (3.4 years; 1.8–4.5; p = 0.010) after the second recurrence.
Conclusions
Repeated LR for recurrent HCC is the procedure of choice if there are three or fewer tumors.
