Efficacy and Safety Study of Folfox4 Chemotherapy Regimen to Prevent Early Recurrence of Hepatocellular Carcinoma Patients With Portal Vein Tumor Thrombus Following Curative Resection

Curative resective is well-accepted as the predominant treatment for hepatocellular carcinoma (HCC) patients. Unfortunately, the long-term prognosis remains poor due to frequent postoperative recurrence, especially in HCC patients with portal vein tumor thrombus (PVTT). When PVTT invades into the portal vein system, tumor cell spreads and distributes along with the portal vein and its branches,thus resulting in intra-hepatic micro-metastasis which contributes to early recurrence for patients following curative resection. Postoperative adjuvant interventions include TACE, antiviral therapy, immunotherapy, local radiotherapy were applied to prevent recurrence. However, the efficacy and safety of these regimens remains unsatisfactory. Thus new therapeutic strategy remains to be investigated. This study is to investigate the efficacy and safety of Folfox4 chemotherapy regimen to prevent early recurrence for HCC patients with PVTT following curative resection.
