Clinical features and treatment of hepatocellular carcinoma in eight patients older than eighty years of age.
BACKGROUND/AIMS: Most-hepatocellular carcinoma patients are between 40 and 60 years of age, but an increasing number of elderly patients with hepatocellular carcinoma is expected in the future because of the increase in life expectancy seen in many countries. Since elderly patients have a high incidence of comorbid illnesses, it should be useful to examine the clinical features of these patients to select the optimal management strategy for hepatocellular carcinoma. METHODOLOGY: A retrospective review of 111 patients with hepatocellular carcinoma was undertaken to examine the clinical features of 8 patients older than 80 years of age. RESULTS: In the 111 patients with hepatocellular carcinoma, the ratio of males to females was 81:30 and the peak incidence of hepatocellular carcinoma was noted in the seventh and eighth decades in males and females, respectively. Of these, 21 (19%) were type "B" [seropositive for hepatitis B surface antigen (HBsAg) and seronegative for antibody to the hepatitis C virus (anti-HCV)], 69 (62%) were type "C" (seronegative for HBsAg and seropositive for anti-HCV), 3 (3%) were type "B + C" (seropositive for both HBsAg and anti-HCV), and 18 (16%) were type "non-B non-C" (seronegative for both HBsAg and anti-HCV). The peak incidences of type "B" were in the sixth decade, whereas those of type "C" were in the seventh decade in both males and females. Patients with "non-B non-C" were common in their seventies. Of the 111 patients, 6 (5 males and 1 female) were older than 80 years at the time of diagnosis and 2 females became 80 years old during the course of follow-up of hepatocellular carcinoma. All but one of these patients were anti-HCV-positive, stage and clinical stage I or II according to the criteria defined by the Liver Cancer Study Group of Japan, and underwent transcatheter arterial embolization and/or transcatheter arterial infusion chemotherapy. Transcatheter arterial embolization/transcatheter arterial infusion or percutaneous ethanol injection therapy was well tolerated in these patients, and the outcome of these patients was good. However, concomitant underlying diseases other than liver diseases made it impossible or difficult to apply an aggressive management protocol for hepatocellular carcinoma in some patients. CONCLUSIONS: Our results suggest that the overall treatment of hepatocellular carcinoma in the elderly should be similar to that in younger patients, but may be restricted by the concomitant underlying diseases specific to advanced age.
