Popis: Abstract Purpose Familial clustering is a common feature of hepatocellular carcinoma (HCC) as well as a risk factor for the disease. We aimed to assess whether such a family history affected prognostic outcomes in patients with HCC diagnosed at different stages of the disease. Materials/Methods This hospital registry‐based cohort study included 5484 patients initially diagnosed with HCC. Individual family histories of cancer were obtained by interview and reported by trained nurses who constructed three‐generation pedigrees. Overall survival data were compared between cases with and without first‐degree relatives affected by HCC, with adjustment for other potential predictors. Results Of 5484 patients, 845 (15.4%) had first‐degree relatives with a history of HCC. Family history was associated with longer survival in the entire cohort (adjusted hazard ratio [HR] 0.89, 95% confidence interval [CI] 0.80‐0.98, P = .025). A significant trend for reduced risk of death with increasing number of affected family members was also observed (P for trend = 0.018). The stage‐stratified analysis showed that the presence of family history was especially associated with a reduced risk of death in the subset of patients with HCC at a (very) early stage (adjusted HR 0.83, 95% CI 0.69‐0.99; P = .042). The proportion of cases receiving curative treatment was also higher in early‐stage patients with a family history (72.6% vs 63.3%; P
