Cancer mortality in Italy, 2003.

AIMS AND BACKGROUND

This report provides data and statistics for cancer mortality in Italy in 2003, updating previous work on the issue.

METHODS

Cancer death certification numbers by cause and estimates of the resident population in 2003, stratified by sex and quinquennium of age, were obtained from the World Health Organization database. In 2003, cause of death encoding was changed from the 9th to the 10th Revision of the International Classification of Diseases (ICD). All cancers and groups of cancers, classified according to the 10th revision of the ICD, were grouped into 30 categories, besides other and unspecified sites. Mortality rates were age-standardized on the world standard population in five-year age groups up to 80-84 years and 85+.

RESULTS

The total number of cancer deaths in Italy was 167,144 in 2003 (96,127 men and 71,017 women), with age-standardized death rates of 160.63 and 89.32 per 100,000 inhabitants, respectively. Lung cancer mortality in men confirmed the favorable trend, with rates of 43.72/100,000 and 51.68/100,000 in the all ages and truncated groups, respectively. Most other tobacco-related cancers were also declining in men but not in women. Cancers of the female breast and uterus (cervix and corpus) continue to decrease, with overall rates of 17.11/100,000 and 3.71/100,000. Declines were also observed in stomach and testis cancers. A few cancer sites such as prostate and multiple myeloma appeared to rise, but these trends were mainly due to the ICD change and the stricter age-standardization categories (80-84 and 85+ instead of 80+).

CONCLUSIONS

Trends in cancer mortality remained favorable for most major cancer sites, mainly in men for tobacco-related cancers. Due to the classification changes brought about by the change of ICD and the stricter age standardization, the present mortality rates should only be compared to previous ones with due caution.
