A group of 10,600 persons in Denmark was followed for death and cancer cases between 1970 and 1987. All of the workers were classified as working in laundries, cleaning and dyeing by the 1970 census. Seventeen cases of primary liver cancer and 16 cases of renal cell carcinoma were observed in this group. All 17 patients with primary liver cancer worked in laundries in 1970. Thirteen of 16 patients with renal cell carcinoma worked in laundries in 1970, and three worked in dry cleaning shops. The fact that this study showed no cases of primary liver cancer observed in dry cleaning workers indicated that the excess risk of primary liver cancer was not likely caused by exposure to dry cleaning solvents. The results did not support previous observations of an excess risk of renal cell carcinoma among dry cleaning workers.
