  • Title: An increased risk for lung cancer mortality associated with sugarcane farming.
    Author: Rothschild H, Mulvey JJ.
    Journal: J Natl Cancer Inst; 1982 May; 68(5):755-60. PubMed ID: 6951086.
    Abstract:
    In a study to determine putative occupation-related factors responsible for the excessive mortality due to lung cancer in southern Louisiana, the next-of-kin were interviewed of 284 of 400 persons (71%) randomly sampled from a total of 815 persons who died of lung cancer during 1971 through 1977 and had lived in any of 10 parishes (counties) of southern Louisiana. Of the decedents, 108 (38%) had been employed for at least 6 months as sugarcane farm workers at some time during their lives. Logistic regression analysis indicated this industrial involvement differed significantly (P less than 0.0001) from that of a control group, consisting of persons who had died of any cause other than lung cancer and who were matched for year of death, age, sex race, and parish of residence; only 58 (20%) matched controls had had sugarcane farm employment (odds ratio = 2.4; 95% confidence interval, 2.0-2.9). Employment in other industries or tobacco consumption could not account for the elevated risk of lung cancer mortality associated with sugarcane farming. After adjustment for smoking, the relative risk estimate of lung cancer mortality for sugarcane farm workers was 2.4 (95% confidence limits, 1.7-3.6). The sugarcane farmers who died with lung cancer had worked for longer periods in the sugarcane farm industry than did those sugarcane farmers in whom lung cancer did not develop (P = 0.006). No specific histopathologic cell type was noted to be increased in persons who had been employed in sugarcane farming; however, 2 sugarcane farmers had had mesotheliomas.
