BACKGROUND: Robotic (RLR) and laparoscopic liver resection (LLR) for hepatocellular carcinoma (HCC) provide similar short-term outcomes, but data focused on recurrence and survival are still lacking. We hypothesized non-inferior oncologic results of RLR compared to LLR for HCC of stage BCLC 0-A.
METHODS: RLRs and LLRs on patients with HCC of stage BCLC 0-A and preserved liver function (Child A or B if cirrhosis) were retrospectively reviewed. Propensity score matching (PSM) was used to mitigate selection bias. The primary endpoints were recurrence-free (RFS) and overall survival (OS); secondary endpoints were incidence, pattern, and treatment of recurrences.
RESULTS: After 1:1 PSM, two groups (RLR = 68; LLR = 68) of patients with similar characteristics, liver function and HCC features were obtained: median age 71-years, males 73.5%, underlying cirrhosis 91.2% (Child A, 96.8%, MELD ≤ 9, 96.0%), portal hypertension 22.1%, single-HCC 90.4%. Two- and 5-year RFS were 78.0 vs 59.0% and 54.0 vs 53.0% (p = 0.107), while OS was 97.0 vs 90.0% and 87.0 vs 90.0% (p = 0.951) for RLR vs LLR, respectively. Incidence of HCC recurrence was similar (35.3 vs 39.7%; p = 0.723). Recurrences developed mostly within the liver (29.4 vs 30.9%; p = 1.000) and within 2 years after hepatectomy (19.1 vs 32.4%, p = 0.116) in RLR vs LLRs. Curative-intent treatment of recurrences did not differ (liver transplantation 19.6%, redo-resection 15.7%, locoregional treatments 52.9%) except for a tendency toward more redo-resections for recurrences after RLR.
CONCLUSIONS: Oncologic outcomes of RLR were not inferior to those of LLR in selected HCC patients of stage BCLC 0-A with underlying cirrhosis. Both techniques guaranteed similar salvageability in case of HCC recurrence.
