Barcelona clinic liver cancer-stage C hepatocellular carcinoma

Abstract

Background: Patients with Barcelona Clinic Liver Cancer (BCLC) stage C hepatocellular carcinoma (HCC) have variable long-term outcomes. Better delineation of prognosis is important for clinical trial enrollment and clinical practice in an era of precision medicine. We hypothesized that stratification of patients with BCLC stage C HCC by presence of vascular invasion and/or metastasis improves prognostic discrimination. Methods: Using a prospectively maintained database, we identified 234 patients diagnosed with BCLC stage C HCC between 2005 and 2015. Patients were stratified into 3 groups based on tumor characteristics: (1) vascular invasion alone, (2) metastasis alone, and (3) vascular invasion and metastasis. Overall survival (OS) was compared using a Cox model. A subgroup analysis was performed based on extent of vascular invasion and site of metastasis. Results: The cohort comprised 123 patients (53%) with vascular invasion alone, 34 (15%) with metastasis alone, and 77 (33%) with both vascular invasion and metastasis. Median survival was 5.7, 3.9, and 3.0 months, respectively (P<.01). Patients with vascular invasion or metastasis alone had significantly better survival compared with those with vascular invasion and metastasis (adjusted hazard ratio [HR],0.68; 95% CI, 0.49-0.94, and HR, 0.61; 95% CI, 0.39-0.96, respectively). Compared with tumoral invasion of branch portal veins, involvement of the main portal vein was associated with worse survival (HR, 2.13; 95% CI, 1.29-3.49). OS did not differ by site of metastasis. Conclusions: Stratification of patients within the BCLC stage C staging subgroup by vascular invasion and presence of metastasis further discriminates patient prognosis. This substratification may have implications for therapy and more accurate prognostic features.
