This study was designed to assess the clinical usefulness of imaging for predicting the prognosis of patients with combined hepatocellular cholangiocarcinoma (cHCC-CC). Between 1999 and 2004, 30 patients with histopathologically proven cHCC-CC underwent computed tomography (CT) or magnetic resonance imaging (MRI). The imaging data and survival were analysed. Univariate log-rank analysis of imaging findings revealed that tumour necrosis, bile duct invasion, major vascular branch invasion, multiplicity, bilobar distribution, regional lymph node involvement, regional organ invasion, distant metastasis and ascites had adverse influences on overall survival. Multivariate Cox proportional hazard analysis demonstrated that major vascular branch invasion, regional organ invasion, nodal and distant metastases were independent prognostic factors that adversely affected overall survival rates. Overall cumulative survival rates at 1, 3 and 5 years were 53%, 26% and 12%, respectively. Analysing the survival of our patients by using clinical stages of the newly updated American Joint Committee on Cancer (AJCC) classification for liver neoplasm based on the imaging findings, we found significant differences between stages I/II and III (p < 0.001) and between stages III and IV (p = 0.040). We conclude CT or MRI can be used to identify the prognostic factors and to estimate the outcomes of patients with cHCC-CC.
