Abstract

The purpose of the study was to analyse patterns of DNA content in hepatocellular carcinomas (HCC) submitted to orthotopic liver transplantation (OLT). Paraffin-embedded archival material from 15 patients (ten men, five women, mean age 51 +/- 1.78 years) transplanted in St-Roch Hospital between 1988 and 1991 was available for laboratory evaluation by flow cytometry. Five out of 15 were incidental HCC. The analysis was performed by a FACSscan flow cytometer coupled to a Hewlett-Packard computer. The cellular DNA content was defined as diploid or aneuploid in the presence of a single (DNA index of 1) or two distinct (DNA index different from 1) Gzero/G1 peaks, respectively. All incidental HCC (five patients) were diploid, the tumour size was 1.2 +/- 0.2 cm, the number of nodules was 1.4 +/- 0.24 and the mortality rate was 40%. No death in the incidental HCC group was related to neoplastic recurrence. In the remaining ten patients transplanted for HCC, we observed 50% diploid tumours, the tumour size was 5.2 +/- 1.55 cm and the number of nodules was 2.7 +/- 0.56. In this group six patients died of neoplastic recurrence (two were diploid and four aneuploid). The diameter of the neoplasm in diploid patients who died of neoplastic re...Continue Reading
