ABSTRACT
This study aimed to investigate outcomes and recurrence patterns after hepatectomy for hepatocellular carcinoma (HCC) patients with different China Liver Cancer staging (CNLC), and then analyze the risk factors of different recurrence patterns. A total of 731 HCC patients undergoing curative resection were reviewed from 6 independent institutions. Data on preoperative and clinicopathological parameters, operation and tumor recurrence information, recurrence management and long-term outcomes were analyzed. Our results showed that 1-, 3-, and 5-year OS rate for Ia was 96.6%, 88.5%, and 77.4%, while 1-, 3-, and 5-year of Ib was 84.2%, 65.5%, and 51.3%, respectively. Compared to Ia, the patients in IIa and IIb staging had poorer 1-, 3-, and 5-year OS and DFS. Furthermore, the 1-, 3-, and 5-year OS rate in IIIa was 59.3%, 37.3%, and 27.7%, while the 1-, 3-, and 5-year OS of IIIb was 25.6%, 12.8%, and 0%, respectively. The mostly site of recurrence after liver surgery was intrahepatic recurrence (CNLC Ia: 89.4%; Ib: 65.9%; IIa: 68.9%; IIb: 91.7%; IIIa: 63.8%). However, the CNLC IIIb patients have higher percentage of extrahepatic recurrence (56.5%). The main recurrence pattern of time course was late recurrence in CNLC Ia patients (61.1%). However, the rate of early recurrence in Ib, IIa, IIb, IIIa, IIIb patients was 69.0%, 62.2%, 62.5%, 78.3% and 95.7% respectively. In conclusion, the outcomes and recurrence patterns of HCC patients after resection vary with different CNLC staging, which defined the prognosis of patients with HCC after resection. The HCC patients with CNLC IIIa can also benefit from liver resection. The CNLC staging could be considered in forming management strategies, treatment choice and surveillance for HCC patients.
