[Pinpointing the stage of prostate cancer after radical prostatectomy]

To analyse data of the preoperative examination of patients and histomorphological examination of prostatectomy samples to determine parameters allowing staging prostatic cancer (PC).

27 patients with staged clinically diagnosed PC have undergone radical prostatectomy with histomorphological examination of the intraoperative samples of the prostate.

The preoperative evaluation of PC has revealed no cases with Glisson's scale (GS) score under 5. Only 8.7% of the tumors were well differentiated, of them 28.3% had the score 7 and higher. 85% of the cases were moderately differentiated adenocarcinomas with the score 5 to 7. 33.3% patients had cancer diagnosed by prostatic biopsy (T1c). Nearly 48% had the tumor T2b, T2c. Histomorphologically, 50.7% of tumors were advanced. A high PSA level, a high score by Glisson and a clinical stage of the tumor at least T2b indicated high probability of extracapsular spread and of metastases to the lymph nodes each. The Glisson's score was higher at analysis of prostatectomy samples than prostatic biopsy in 10 (37%) cases while it was lower only in 2 (7.4%) cases. In 5 (18.5%) patients the difference made up 2 and more scores by Glisson.

Thin needle biopsy examinations underestimate PC stage. To stage and predict the disease course precisely it is necessary to make a multifactor analysis.
