Abstract

Results of several studies on DNA ploidy as a prognostic indicator in hepatocellular carcinoma are contradictory. The present study analysed the correlations between DNA ploidy of resected hepatocellular carcinoma and tumour characteristics, tumour recurrence, risk factors and survival. Tumoural DNA ploidy of hepatocellular carcinomas from 37 patients with cirrhosis who underwent curative tumour resection was studied by flow cytometry. A diploid pattern was found in 23 hepatocellular carcinomas (62.2%) and an aneuploid pattern in 14 (37.8%). The tumour recurrence rate did not differ statistically between diploid (69.6%) and aneuploid (50%) hepatocellular carcinomas. The only prognostic variable with significant difference in DNA pattern was the histologic tumour type; the majority of non-trabecular tumours were aneuploid while most trabecular hepatocellular carcinomas had a diploid DNA pattern. Actuarial survival at 1, 2, 3 and 4 years of patients with diploid and aneuploid tumours was 69.6%, 40.6%, 16.2% and 0%, and 69.3%, 59.4%, 49.5% and 32.9%, respectively (log rank p = 0.1927). These results indicate that DNA ploidy has no prognostic value in hepatocellular carcinoma.
