Abstract

Nuclear DNA ploidy has been shown to have an important prognostic association for patients with adenocarcinoma of the prostate. Flow cytometry and static image analysis are ploidy methods that have been used in prostate carcinoma. Fluorescence in situ hybridization (FISH) using chromosome-specific probes can be used to evaluate the ploidy of interphase nuclei. In this study FISH was compared with flow cytometry and static image analysis in determining ploidy in paraffin-embedded tissue from 34 prostatic adenocarcinomas. Ploidy status using FISH was determined by enumerating centromeres of two chromosomes (8 and 12) by use of directly-labeled α-satellite DNA probes in isolated whole nuclei obtained by the Hedley technique. All three methods identified 11 of 34 cases as diploid and 17 of 34 cases as nondiploid (82% concordance). Six cases were discordant; two cases had discrepant results by each method. Ploidy classification as determined by FISH had an 88% concordance with ploidy classification by either flow cytometry or static image analysis. In conclusion, FISH was found to be a sensitive method of ploidy analysis in isolated paraffin-embedded nuclei from prostate adenocarcinomas. When the chromosomes commonly involved in aneuploidy have been identified in prostate adenocarcinoma, FISH has the potential to provide greater sensitivity for aneuploidy detection compared with currently available methods.
