Background
There is still poor evidence about the safety and feasibility of laparoscopic liver resection (LLR) for huge (> 10 cm) hepatocellular carcinomas (HCC). The aim of this study was to assess the short- and long-term outcomes of LLR versus open liver resection (OLR) for patients with huge HCC from real-life data from consecutive patients.
Methods
Data regarding all consecutive patients undergoing liver resection for huge HCC were retrospectively collected from a Korean referral HPB center. Primary outcomes were the postoperative results, while secondary outcomes were the oncologic survivals.
Results
Sixty-three patients were included in the study: 46 undergoing OLR and 17 LLR. Regarding postoperative outcomes, there were no statistically significant differences in estimated blood loss, operation time, transfusions, postoperative bile leak, ascites, severe complications, and R1 resection rates. After a median follow-up of 48.4 (95% CI 8.9–86.8) months, there were no statistically significant differences in 3 years OS (59.3 ± 8.7 months vs. 85.2 ± 9.8 months) and 5 years OS (31.1 ± 9 months vs. 73.1 ± 14.1 months), after OLR and LLR, respectively (p = 0.10). Similarly, there was not a statistically significant difference in both 3 years DFS (23.5% ± 8.1 months vs. 51.6 ± months) and 5 years DFS (15.7 ± 7.1 months vs. 38.7 ± 15.3 months), respectively (p = 0.13), despite a potential clinically significant difference.
Conclusion
LLR for huge HCC may be safe and effective in selected cases. Further studies with larger sample size and more appropriate design are needed to confirm these results.
