Buccal micronucleus cytome assay to evaluate cyto-genotoxic effects of occupational exposure to antineoplastic drugs: application on a large sample size of workers furnished by an Italian network of oncological hospitals.
Article in Archives of toxicology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Many antineoplastic drugs (ADs) used to treat cancer are characterized by the non-selective effect representing a possible cause of health effects in exposed workers. We established an Italian Network of seven Oncological Hospitals with the aim to evaluate, on a large size sample of workers, cyto-genotoxic effects by a sensitive and non-invasive biomarker also detecting workplace and personal contamination. We performed Buccal Micronucleus Cytome (BMCyt) assay on 200 workers handling ADs and 150 controls. AD contamination was detected performing workplace and personal monitoring of Gemcitabine, Ifosfamide, Cyclofosfamide and 5-Fluorouracil, using UHPLC MS/MS. We found in all the exposed group higher mean values of cells with micronucleus (MN‰), higher percentage of positivity to MN (subjects with micronucleated cells frequency exceeding a fixed cut-off value (1.5‰)), higher frequency of binucleated cells, broken eggs and total anomalies than in the controls. Taking into account the tasks (preparation, administration in Day Hospital and wards, administration in room operator and disposal), only preparators and administrators showed higher MN‰ frequency than in controls, whereas each task group showed a similar higher percentage of MN positives than in controls. We found low levels, but still detectable, of contamination in all the monitored workplaces. This study demonstrated induction of genotoxicity and of cytokinesis defect/arrest in buccal cells of workers handling antineoplastic drugs. The BMCyt assay was demonstrated to be a suitable biomarker of effect for biomonitoring of workers handling AD due to its high sensitivity and non-invasivity.
