This short report provides data and statistics of cancer mortality in Italy in 1998, updating previous work on the issue. The material and methods of this report are similar to those previously described. Briefly, cancer death certification numbers by cause and estimates of the resident population in 1998, stratified by sex and quinquennia of age, were abstracted from data provided by the Istituto Nazionale di Statistica (ISTAT). All cancers or groups of cancers, classified according to the standard International Classification of Diseases (ICD), Ninth Revision, were grouped in 31 categories, besides total cancer mortality and other and unspecified sites. We grouped together all intestinal sites, melanomas and non-melanomatous skin neoplasms, all uterine neoplasms (cervix and corpus), all neoplasms of the brain and nerves (benign and malignant), all leukemias, and all non-Hodgkin's lymphomas. Eight tables were produced, including the following statistics: 1) number of deaths, crude and age-standardized death certification rates, and percentages of all cancer deaths for population at all ages and truncated 35-64 years (Table 1 for males and Table 2 for females). Two different standards were used: i) the 1971 Italian census population, corrected for census undercount and subdivided into 16 quinquennia of age from 0-4 to 75-79, plus 80 and over, and ii) the world standard population, for purposes of comparison with other countries; 2) age-specific death certification rates for each sex and quinquennium of age from 0-4 to 75-79, plus 80 and over (Table 3 for males and Table 4 for females); 3) total number of registered deaths for each cancer or group of cancers, sex and age group (Table 5 for males and Table 6 for females); 4) percentage of all cancer deaths for each sex and age group (Table 7 for males and Table 8 for females). A few comments are included, mainly in order to assist reading and interpretation of data for major cancer sites, and to recall underlying long-term tendencies. Any inference should in any case be based on age-standardized rates, and, essentially, on detailed inspection of age-specific rates.
