Objective:
To evaluate the long-term outcomes of surgery for recurrent hepatocellular carcinoma (HCC).
Background:
HCC recurs with high incidence after liver resection. Little is known about long-term outcomes of patients undergoing surgery for recurrent HCC.
Methods:
Among 989 patients who underwent R0/R1 liver resection for HCC between 1995 and 2014, 676 patients who exhibited recurrence were included. Repeat surgery was performed in 128 patients (RS group), and not in the remaining 548 patients (NS group). Prognostic value after repeat surgery was evaluated by comparing survival after recurrence (SAR) between the RS and NS groups. Subgroup analyses according to the 3 recurrence patterns [intrahepatic recurrence (IHR), extrahepatic recurrence (EHR), and intra plus extrahepatic recurrence (IHR + EHR)] were performed.
Results:
Seventy-three of 430 patients (17.0%) with IHR, 17 of 57 patients (29.8%) with EHR, and 38 of 189 patients (20.1%) with IH + EHR underwent repeat surgery. Compared with the NS group, the RS group had better liver function and their time to recurrence was significantly longer (16.5 vs 11.4 months; P < 0.001). In the overall and 3 recurrence patterns, the 5-year SAR rate was better in the RS group compared with the NS group (RS vs NS group; overall, 53.0% vs 25.7%; IHR, 73.8% vs 37.2%; EHR, 30.0% vs 0%; IHR + EHR, 34.1% vs 10.6%; all P < 0.001, respectively). On multivariate analysis, repeat surgery was identified as an independent factor for better SAR (P < 0.001).
Conclusion:
Surgery for recurrent HCC may yield long-term survival for not only IHR but also for EHR in selected patients.
A preoperative prognostic model incorporating F-FDG-PET imaging with the ALBI grade may be useful for estimating the prognosis of selected patients with solitary HCC.
A novel biomarker-based preoperative prognostic grading system for ICC significantly stratifies survival after surgery and may identify patients requiring further treatment.
Backgrounds: Prognosis for patients with advanced intrahepatic cholangiocarcinoma (ICC) with intrahepatic metastasis (IM), vascular invasion (VI), or regional lymph node metastasis (LM) remains poor. The aim of this study was to clarify the indications for surgical resection for advanced ICC. Methods: We retrospectively divided 213 ICC patients treated at Kyoto University Hospital between 1993 and 2013 into a resection (n=164) group and a non-resection (n=49) group. Overall survival was assessed after stratification for the presence of IM, VI, or LM. Results: Overall median survival times (MSTs) for the resection and non-resection groups were 26.0 and 7.1 months, respectively (p<0.001). After stratification, MSTs in the resection and non-resection groups, respectively, were 18.7 vs. 7.0 months for patients with IM (p<0.001), 23.4 vs. 5.7 months for those with VI (p<0.001), and 12.8 vs. 5.5 months for those with LM (p<0.001). Conclusion: When macroscopic curative resection is possible, surgical resection can be justified for some advanced ICC patients with IM, VI, or LM.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
