Analysis of Prostate Adenocarcinoma Histopathological Types in Relation to Tumor Grade.

Prostate adenocarcinomas are some of the most common malignancies diagnosed in men, and the evaluation of tumor growth patterns is the basis for establishing the aggressiveness of the lesions. The study included 283 cases of prostate adenocarcinomas for which histopathological type and tumor grade were analyzed. The results indicated the association of ductal, sarcomatoid and signet ring-like cell types with aggressive growth patterns and high scores, atrophic and pseudohyperplastic types with mild growth patterns and low scores, foamy gland type presented intermediate growth patterns/scores, while conventional and colloid types had variable aspects. The grading systems used may be considered consistent with the histological types of prostate adenocarcinomas.
