[Trends in urologic neoplasm mortality and incidence (prostate, bladder, and kidney). Soria, 1950-1988]

The mortality rate for urological tumors in the province of Soria, Spain, was recorded from 1950 to 1988, as well as its incidence for the period 1981-1988. We classified data according to sex, age groups, tumor site and type, and patient residence (urban/rural). Rates were adjusted for the foregoing parameters and decades (1950-1959, 1960-1969, 1970-1979, 1980-1988) and compared with those of other national and international registries. Prostate, bladder and kidney tumors in men showed an increased mortality rate for the period 1950-1988 which was statistically significant (p less than 0.01), whereas the female mortality rate for this period hardly changed and remained very low. A higher risk potential was observed for bladder tumors for the urban than for the rural areas, with a significant difference for mortality and incidence for both sexes (p less than 0.01). There was also a higher incidence for tumors of the prostate in the urban areas (p less than 0.01). Like most registries, there was a prevalence of bladder tumors in males, in both areas, in mortality and incidence (p less than 0.01). Comparison with other national registries show our mortality and incidence rates are lower for both sexes. Comparison with international registries show this province has a medium-low risk for prostatic tumors and medium risk for bladder tumors in males and females. The risk potential for renal tumors could not be compared objectively. The incidence/mortality ratio (I/M) (adjusted rates) shows prognosis is good for bladder tumors (better in women than in men), poor for prostatic tumors, and bad for renal tumors.
