Abstract
A total of 115 articles on prostate cancer were reviewed for data on the prognostic value of DNA content in the tumor cells. In 44 series, data pertinent to this review were found. There was no consensus in the literature with respect to methods of analysis of DNA content or definitions of subclasses of DNA content such as categories of ploidy. The DNA content of prostate cancer cells was strongly related to tumor grade and stage. When analyzed as a single parameter in univariate analyses, the DNA content had a prognostic value with respect to overall or disease-specific survival. In multivariate analyses the additional prognostic value of the DNA content was less convincing when analysed with tumor grade and stage. The prognostic data from univariate and multivariate analyses available in the literature were mainly derived from patients with advanced disease and data on localized, potentially curable disease were scanty and conflicting.
