NEW YORK (Reuters Health) - Diabetes is a predictor of poor outcome in patients who have hepatocellular carcinoma related to hepatitis C virus infection (HCV), Japanese investigators report in the September issue of the American Journal of Gastroenterology.
As senior investigator Dr. Shuichi Kaneko told Reuters Health, "Diabetes is a risk factor not only for development of hepatocellular carcinoma, but also for recurrence after operation."
Dr. Kaneko and colleagues at Kanazawa University retrospectively studied 90 patients with hepatitis B and/or C who had undergone surgical treatment for hepatocellular carcinoma. Of this group, 30 had diabetes and the remaining 60 were diabetes-free.
In all, 49 patients had recurrence after surgery. Of these, 22 were from the diabetic group (73.3%) and 27 (45.0%) were from the non-diabetic group. Mean time to recurrence was 32.8 months.
The researchers found that there was no significant difference in survival between diabetic patients and non-diabetic patients with hepatitis B-related hepatocellular carcinoma.
However, comparison of diabetic and non-diabetic patients with HCV-related disease showed that survival rates at 3 years and beyond were significantly lower in the diabetic group than among the non-diabetics. Survival rates at 5 years, for example, were 43.8% versus 82.6%, respectively.
Given these findings, concluded Dr. Kaneko, diabetic patients "should be closely followed for this carcinoma."
