Is Micronucleus Assay a Suitable Biomarker for Evaluating the Cancer Risk in Professionals Exposed to Antineoplastic Drugs? A Systematic Review

Year: 2025

Type: review

Abstract: The widespread use of antineoplastic drugs in cancer treatment has led to significant concerns regarding the potential health risks posed to healthcare professionals involved in the preparation, administration, and handling of these chemical compounds, including genotoxicity. This systematic review investigates the genotoxicity of various anticancer drugs through the micronucleus assay in mammalian cells through a comprehensive analysis of studies retrieved from PubMed, SCOPUS, and Web of Science. A systematic search conducted in May 2025 identified 28 relevant studies, all of which employed the micronucleus assay. The results indicated that 23 of the reviewed studies observed genotoxic effects linked to several drugs. As for the quality assessment, all studies (but one) were categorized as either strong or moderate; therefore, we consider our findings to be reliable. These findings raise significant concerns regarding the potential health risks associated with oncologic drugs, warranting further investigation and regulatory oversight to ensure professionals' safety. Finally, such findings are very important for clarifying the role of the micronucleus assay as a putative biomarker for evaluating the cancer risk due to anticancer drug exposure in humans.
