Exposure to Antineoplastic Agents Induces Cytotoxicity in Nurse Lymphocytes: Role of Mitochondrial Damage and Oxidative Stress

Abstract

Cytotoxicity and mitochondrial parameters were studied in isolated lymphocytes and their mitochondria obtained from occupationally exposed nurses through inhalation exposure to antineoplastic drugs and results were compared to those of unexposed nurses. The group of occupationally exposed nurses consisted of 50 individuals ranging in age from 30 to 35 years. The control group included 50 nurses who were not occupationally exposed to the preparation and handling of antineoplastic drugs and their anthropometric and biochemical characteristics were similar to those of the expose group. All cytotoxicity and mitochondrial parameters evaluated in exposed group were significantly increased (P < 0.05) compared to the unexposed control group. Finally, the results of our study suggest that using antioxidant, mitochondrial and lysosomal protective agents can be promising drug candidates for the hospital staff in the risk of exposure to exposure to antineoplastic drugs.
