Exposure to cytostatic drugs was assessed in a group of 9 nurses employed in a hospital cancer therapy department by measuring the post-shift levels of urinary mutagens and cis-platinum. A slight but significant increase in urinary mutagenic activity compared to 11 controls was observed in the non-smokers: the mean values of mutagenic activity on the Ta100 strain in the presence of both microsomal and deconjugating enzymes were 4418 +/- 1186 and 2468 +/- 1681 respectively.

The increased urinary mutagenic activity in the exposed group can probably be attributed to the absorption of cyclophosphamide either during preparation and administration of the drug, or due to accidental contact with contaminated biological fluids, in view of the fact that the level of mutagens in urine samples from cyclophosphamide-treated patients is extremely high (up to 319,478 revertants/g creatinine in the case we examined).

Abstract

Exposure to cytostatic drugs was assessed in a group of 9 nurses employed in a hospital cancer therapy department by measuring the post-shift levels of urinary mutagens and cis-platinum. A slight but significant increase in urinary mutagenic activity compared to 11 controls was observed in the non-smokers: the mean values of mutagenic activity on the Ta100 strain in the presence of both microsomal and deconjugating enzymes were 4418 +/- 1186 and 2468 +/- 1681 respectively. Conversely, the urinary platinum concentration was below the detection limit of the analytical method (10 micrograms/l) in all samples. The increased urinary mutagenic activity in the exposed group can probably be attributed to the absorption of cyclophosphamide either during preparation and administration of the drug, or due to accidental contact with contaminated biological fluids, in view of the fact that the level of mutagens in urine samples from cyclophosphamide-treated patients is extremely high (up to 319,478 revertants/g creatinine in the case we examined).
