[Mortality from malignant tumors in the industrial region of the province of Milan, 1980-1987].
For the period 1980-87 mortality data relating to residents of a densely populated area in the province of Milan was collected and elaborated. The area is heavily industrialised and had a particularly high immigration level in the 1960's and 70's. Malignant neoplasms represented the cause of death in 35.59% of male cases and 26.59% of female, with greater incidence in the former of tumours in respiratory organs and in the latter in the digestive tract. High mortality rates were noted for cancer of the lung in males over 35 years and for neoplasms of the digestive tract in those over 75 years but in females high mortality from breast cancer prevailed between 25-74 years and cancer of the stomach and intestine in those over 75 years. S.P.M.R. were elaborated with proportional mortality analysis showing an overall tendency to an increased death rate from malignant tumours that was statically significant in females, particularly at an advanced age. Increasing trends in tumours of the stomach and of the lympho-hematopoietic tissues were evident in females, in urinary organs in males, notably in elderly men, and in intestinal cancer in both sexes. The trend in mortality from breast cancer was however on the decline. As a whole, mortality was stationary in cases of cancer of the lung (although it was on the increase in females over 65 years), in cancer of the prostate (showing a decrease however in older subjects) and in cancer of the uterus and ovaries (but increasing in the latter case in elderly women). By means of S.M.R. elaboration the data was compared with that in Lombardy. In the area being taken into consideration a picture emerged of cancer mortality in general which was virtually the same as that found in Lombardy. However, the result of the comparison differs when considering sex and age groups. In fact in the 35-64 age group an inferior mortality rate to the Lombardian one was noted in the total population and in women, whilst for the age group 65 and over, a higher mortality rate emerged in men and in the total population. In males mortality was lower stomach tumours and higher for lung cancer, especially in more elderly subjects. Cancer of the colon-rectum, uterus and breast did not show statistically significant differences. The comparison with Italian data effected with direct age-standardisation has shown higher mortality from stomach, intestinal and lung cancer in the area being studied.(ABSTRACT TRUNCATED AT 400 WORDS)
