To study the effects of habitual alcohol intake and cigarette smoking on the latency period for the development of hepatocellular carcinoma (HCC), 455 patients with HCC were analyzed with respect to age at diagnosis. They were divided into hepatitis B virus (HBV) positive and negative patients based on HbsAg and high titer anti‐HBc in serum. HBV‐positive and negative HCC patients were further subdivided into four subgroups based on the history of drinking more than one small bottle of Japanese “sake” or its equivalent per day for more than 10 yr and the history of smoking more than one cigarette per day for more than 10 yr. Among HBV‐positive HCC patients, the average age of those with a drinking and a smoking habit (50 ± 10 yr) was younger compared with that of patients with a drinking habit but without a smoking habit (56 ± 14 yr, not significant, NS), of those who were smokers and nondrinkers (55 ± 10 yr, NS) and of those who did not drink nor smoke (59 ± 8 yr, p < 0.005). Among HBV‐negative HCC patients, patients with drinking and smoking habits (57 ± 9 yr) were younger compared with those with a drinking habit without smoking (59 ± 9 yr, NS), those who were smokers and nondrinkers (62 ± 9 yr, p < 0.005), and those who were nondrinkers and nonsmokers (63 ± 12 yr, p < 0.005). These data suggest that habitual alcohol intake may promote the development of HCC if the patients smoke cigarette regardless of the status of HBV seromakers.
