Bladder cancer mortality in the Epirus district population (Greece).
OBJECTIVE
To describe the pattern of bladder cancer mortality in the Epirus district population (North-Western Greece) and to establish some relationships with cigarette smoking.


METHODS
Mortality rates of bladder cancer in the Epirus district population were analysed according to the official data from the Department of Statistics of the University Hospital of Ioannina during the last decade (January 1990-January 2000). Age standardization of death rates was done by the direct method, using the world population as a standard. Fisher's test was used as a significance test for linear regression coefficient in time trend analysis of mortality.


RESULTS
The average annual standardized mortality rates from bladder cancer during the study period were 5.23 per 100,000 population (96% Confidence Interval--Cl 4.02-5.63) in males and 1.63 per 100,000 population (96% Confidence Interval--CI 1.18-1.96) in females. Significantly increasing trends of the rates were observed in males (y = 2.421 + 0.231x; p < 0.01), but not in females (y = 1.263 + 0.027x: p > 0.05). The greatest increase in age - specific rates in males was observed in the age group of 70 and more years (y = 25.602 + 3.673x; p < 0.01). In females, all age--specific rates except for the group 60-69 years showed significantly increasing tendency. The increasing tendency of bladder cancer mortality is followed by the rise of per capita cigarette consumption among the Epirus district population.


CONCLUSIONS
Further studies are needed for the explanation of the irregularities in the age-specific rates.
