Improvement of overall survival among all patients with hepatocellular carcinoma according to the registration period. A comparison of cumulative overall survival among patients newly registered between 1978 and 2009 (n = 157 758) divided into four groups by registration date. The median overall survival and cumulative survival rates (5‐year/10‐year) were 4.99 months and 11.9%/5.0% for group 1 (1978–1985, n = 5551), 25.63 months and 31.9%/10.1% for group 2 (1986–1993), 42.97 months and 39.7%/20.6% for group 3 (1994–2001, n = 53 775), and 60.81 months and 50.4%/24.0% for group 4 (2002–2009, n = 65 711).
