To provide a descriptive, epidemiologic approach a study of geographical correlations of ageadjusted death rates from malignant neoplasms by individual site, and factor analyses were applied to data from 33 countries, based on the latest W.H.O. statistics.The highest correlations between males and females were found for the stomach, followed by the intestines, and the rectum. The lowest correlations were observed for the buccal cavity/pharynx. Among the different sites, very high correlations for males were noted for the buccal cavity/pharynx and the esophagus, and the buccal cavity/pharynx and the larynx. Marked inverse correlations between stomach cancer and leukemia were found. High correlations were found for breast and intestinal cancers in females, whereas there were inverse relationships between breast and stomach cancers. Sites that had consistently high partial as well as Pearsons correlations were the buccal cavity/pharynx and the esophagus (both sexes), the buccal cavity/pharynx and the larynx, the larynx and bone (both in males), and the breast and intestines (females).Factor analyses identified six major factors, of which the first appeared to contribute to intestinal and rectal cancers (both sexes), breast cancers (females), and lung cancers (males); the second to stomach cancer and leukemia; the third to bone (both sexes), laryngial (males), and breast cancers (males); the fourth to cancers of the buccal cavity/pharynx, esophageal cancers, and lung cancers (all in females); the fifth to skin cancer; and the sixth to cancers of the buccal cavity/pharynx and esophageal cancers (both in males).The second factor appeared to effect stomach cancer and leukemia in reverse directions. The connection between bone and laryngial cancers in males was found in their correlations and factor analyses.
