The aim of this work was to evaluate DNA damage in white blood cells from 63 nurses who handle antineoplastic drugs in five Italian hospitals and 74 control participants, using different versions of the Comet assay. Methods Primary DNA damage was assessed by using the alkaline version of the assay on leucocytes, whereas to detect DNA oxidative damage and cryptic lesions specifically, the Comet/ENDO III assay and the Comet/araC assay were performed on leucocytes and lymphocytes, respectively. Results In the present study, no significant DNA damage was correlated with the work shift. The exposed population did not differ significantly from the reference group with respect to DNA primary and oxidative damage in leucocytes. Strikingly, in isolated lymphocytes treated with araC, lower data dispersion as well as a significantly lower mean value for the percentage of DNA in the comet tail was observed in exposed participants as compared with the control group (p\<0.05), suggesting a potential chronic exposure to crosslinking antineoplastic drugs. Conclusions Although stringent rules were adopted at national and international levels to prevent occupational exposure to antineoplastic drugs, data reported in this study support the idea that a more efficient survey on long-lasting exposures at very low concentrations is needed.}, issn = {1351-0711}, URL = {https://oem.bmj.com/content/70/11/789}, eprint = {https://oem.bmj.com/content/70/11/789.full.pdf}, journal = {Occupational and Environmental Medicine} }
