[Correlation between size and localization of stage-pT adenocarcinoma of the prostate]

According to the data on resected material sampled from 58 cases of radical prostatectomy, a relationship between size of adenocarcinoma and prostate and localization of the main tumor node, on the one hand, and pathological stage (pT) of primary tumor was established. Incidence of pT3 was dependent on tumor volume when adenocarcinoma was in the periphery of the prostate which involved the following relationships between pT, on the one hand, and tumor size and site, on the other: the closer tumor to the gland center, the lower the value of pT. Conversely, peripheral zone size showed the least variation in elderly men. Risk of pT3 appeared to be associated with small size of the prostate. Our findings may be used for identification of tumor size and pathology detection by means of biopsy prior to surgery.
