DNA-ploidy as prognostic factor in prostatic carcinoma. 1990

Department of Pathology/University of Trondheim, Norway.

DNA-ploidy in 143 cases of prostatic carcinoma was assessed by flow cytometric analysis of paraffin-embedded biopsy material. The majority of the tumours (64.3%) were diploid, but in advanced stages the DNA-aneuploidy rate increased from 15 to over 60%. No hypoploid tumour was observed and most of the hyperploid tumours were near-tetraploid. DNA-aneuploidy was also strongly related to histological grade. Survival analysis using Cox multivariate regression model revealed that low histological grade (high Gleason score), advanced stage and increased level of prostatic acid phosphatase were the most important prognostic factors. DNA-ploidy per se did not contribute independently as a predictor of survival.

D012044	Regression Analysis	Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
