Prostate cancer mortality trends in Mexico, 1980-1995

BACKGROUND. In Mexico, prostate cancer (PC) is the second highest cause of mortality by cancer in men. In 1991, there were 2,473 deaths, with a crude rate of 5.66 cases per 100,000 men age 40 or over. For this same year, the ratio of proportional mortality to the total number of malignant tumors was 12.6%. Our objectives were to determine the trends and geographic distribu tion of mortality for PC in Mexico for 1980-1995. METHODS. Crude and adjusted mortality rates were carried out for 1980-1995. A test for trend was done using the simple lineal regression method. The s tandardized mortality ratio (SMR) was calculated for 1980-1995 for each Mex ican state. RESULTS. The total number of deaths by PC in Mexico for 1980-1995 was 32,34 9. The crude mortality rate increased during that period from 3.16 to 6.75 cases per 100,000 men over age 40. The statistical trend test with respect to time was significant (P < 0.0001). The state of Southern Baja California showed a higher SMR, and a smaller SMR was shown for the state of Quintana Roo. CONCLUSIONS. The mortality trends for PC increased for the period studied. It represents a serious problem for public health. We find that the central and northern states of the country, characterized by a greater industrial and socioeconomic development, are those with a higher SMR. (C) 1999 Wiley- Liss, Inc.
