Etiologic Study of Respiratory Cancer in Coastal Texas.
NIOSH 1982 Apr:129-166
Preliminary results of a case/control study of respiratory cancer in coastal Texas were discussed. The purposes of the study was to evaluate environmental factors that could contribute to the increased incidence of respiratory cancer in white residents living along the Texas Gulf coast. The cohort consisted of all cases of lung cancer first diagnosed among 30 to 79 year old residents of Brazoria, Chambers, Galveston, Jefferson, and Orange counties between July 1, 1976 and June 30, 1980 and females living in Harris county between July 1, 1977 and June 30, 1980 and all cases of laryngeal cancer diagnosed in males living in the six county area between July 1, 1975 and June 30, 1980. All cases who were alive were matched to persons on Medicare. Data were collected from hospitals located within the counties and from the statewide cancer registry program of the Texas Department of Health. The data were to be analyzed to assess the roles of residential and occupational exposures, smoking, alcohol use, medical history, family history of cancer, vitamin-A deficiency, and socioeconomic status on the incidence of lung and laryngeal cancer. A total of 805 lung cancer cases and 223 larynx cancer cases were identified, of which 240 and 176, respectively, were still alive. A total of 365 lung cancer cases and all larynx cancer cases were male. The predominant types of lung cancer were epithelial carcinoma, squamous cell carcinoma, and adenocarcinoma. Squamous cell carcinoma was the major type of larynx cancer. Interviews were being conducted with the cases or their next of kin and the comparisons. A discussion of the study was included.
