In systematic studies with alkylating substances, dimethylsulphate (DMS) has been investigated for carcinogenic activity in rats. Subcutaneous injections of 16 and 8 mg DMS/kg respectively, given once a week, produced local sarcomas in 12 out of 18 surviving rats, in some with metastases to the lungs, and in one a carcinoma of the liver. The mean survival time was 300 and 500 days respectively. Hence, DMS is considered as a direct acting carcinogen. A bronchiogenic carcinoma, which caused the death of a 47 year old worker in a chemical industry, is reported and related to exposure to DMS vapours, 11 years before. Its acceptance as occupational cancer is confirmed. In the interest of active cancer prevention, a dose cooperation between industries and experimental carcinogenesis research is recommended.
