THE COMPARISON OF THE OCCURRENCE OF MALIGNANT UROLOGIC TUMORS IN TWO EIGHT-YEAR PERIODS (1980- 1987 COMPARED TO 1998-2005) AT THE LJUDEVIT JURAK UNIVERSITY DEPARTMENT OF PATHOLOGY

AIM OF THE STUDY: According to the department’ s cancer registry data in the last eight years urological cancers represented 32.2% (3015 cases) of all male cancers, and 8.7% (594 cases) of all female cancers. The aim of this study is to determine the frequency and the pattern of urologic cancers diagnosed at our department in two eight-year periods a decade apart. MATERIALS AND METHODS: Histopathological data for the two periods were obtained from the department’ s computer-based carcinoma registry, former being a period of 1980-1987 and the latter of 1998-2005. Patients were assessed according to the sex and the localization of the tumor. RESULTS: 1459 urologic cancers were reported over a period of 1980-1987 (83.6 % in males, 16.4% in females), opposed to 3609 cases (83.5% in males, 16.5% in females) diagnosed in the period of 1998-2005. The organ-specific distribution in males, in the former period, was as follows: urinary bladder 62.5%, prostate 24.7%, kidney 7.5%, testis 3.9% and finally, renal pelvis and ureter with 1.4%. In the latter period prostate cancer (diagnosed in 42.6% of cases) switched places with urinary bladder carcinoma (diagnosed in 36.9% of cases), with the remaining distributions’ ranks staying the same. One must emphasize that the frequency of prostate cancer rises noticeably in the last six years. In females a predominance of bladder tumors was found in both periods (74.2% of all urinary cancers in the first and 59.4% in the second period), followed by kidney and renal pelvis and ureter malignancies. DISCUSSION AND CONCLUSION: The absolute number of all urinary carcinomas increased three to four times during the observed periods, with the absolute number of prostate cancer quadrupling, mostly due to more sophisticated diagnostic methods. The bladder cancer is the most common urinary tumor in females, followed by kidney tumors showing slow but steady absolute and relative increase.
