RESUMO

Objectives: To study the frequency of incidentally found carcinoma of the prostate in autopsies, to find any morphological evidence for a possible better behavior when neoplasia originates in the transition zone, to analyze the histologic grading, and to discuss the terminology used when referring to this neoplasia. Material and methods: The prostates from 150 autopsied men were dissected in transition and peripheral zones through a section passing a plane indicated by the course of the ejaculatory duct, and a step section method was used to cut the prostate in coronal planes in intervals of 0,3-0,5cm. The microscopic examination included presence or absence of carcinoma, extension evaluated according to the percentage of sections showing the neoplasia and histologic grading according to the Gleason system. The data were statistically analyzed thrugh the chi-square test to determine the differences in proportion at a significance level of O,05 ...Note: The complete abstract is available with the full electronic digital thesis or dissertations
