RESIDENCE, AGE, RACE AND RELATED FACTORS IN SURVIVAL AND ASSOCIATIONS WITH SALIVARY TUMORS

Keller, A. Z. (Research Service, DM & S, 151F, Veterans Administration, Washington, D.C. 20420). Residence, age, race and related factors in the survival and associations with salivary tumors. Amer. L Epid. 1969, 90: 269-277.-A nationwide veterans' hospital study of salivary tumors on 90 malignant cases and 90 age-matched controls, plus 59 benign cases, in 1958-1962, revealed that: 1) Neither heavy smoking nor heavy drinking is associated with salivary tumors; this is also true for residence, race, syphilis, diabetes mellitus, rheumatoid arthritis, extra-oral neoplasms and even liver cirrhosis; 2) with increasing age, the overall risk is greater that a tumor will be malignant and not be benign; 3) survivorship is indeed better when the carcinoma type is distinctly glandular rather than epithelial; 4) the rate of survival is twofold greater with benign than with malignant tumors; and 5) yet the survival rates do not significantly differ for the benign by comparison with the localized malignant tumor cases. © 1969, by THE JOHNS HOPKINS UNIVERSITY.
