A new classification for hepatocellular carcinoma with portal vein tumor thrombus

摘要

We aimed to correlate the survival of patients with hepatocellular carcinoma (HCC) with macroscopic portal vein tumor thrombus (PVTT) who underwent partial hepatectomy with or without portal thrombectomy with our PVTT classification. Currently, different staging systems for HCC are widely used in clinical practice. However, they lack the refinement in giving prognosis and guiding surgical treatment once macroscopic PVTT is present.
