Potential cytotoxic contamination in preparing and administrating cytotoxics is still a major source of concern. Besides advanced protections including biological safety cabinets, work surface contamination needs to be continuously controlled to ensure that handling procedures and cleaning were appropriate. Contamination monitoring needs to be standardized.</p><p><strong>Data sources: </strong>The study searched Pubmed/Medline and Embase with\"hazardous drug\", \"cytotoxic drug\", \"surface contamination\", \"environmental contamination\", \"wipe sample\", \"pharmacy\", \"care unit\", and selected studies reporting contamination results in work environment for pharmacy technicians and nurses, from 1 January 2017 to 31 December 2022.</p><p><strong>Data summary: </strong>The 29 studies totalized 16,196 samples and 189,571 assays. Contamination results showed 39.8% sample positivity, and 8.2% assay positivity. Multicentric studies gathering at least 500 samples or up to 800 samples would limit heterogeneity in sample positivity. In addition, monitoring of an appropriate tracer selection including at least the 7 tracers with the highest contamination frequencies (cyclophosphamide, gemcitabine, fluorouracile, ifosfamide, platinum derivatives, paclitaxel and methotrexate) would facilitate contamination comparisons amongst studies and local results. Most recent studies reported thresholds for cyclophosphamide close to 0.1 ng/cm² at the 90^th percentile.</p><p><strong>Conclusions: </strong>The overall risk of exposure for healthcare professionals is a major concern. Sample size in multicentric studies would require at least 500 samples; quantification of all tracers with the highest contamination frequencies need to be quantified. This approach would provide a basis to develop guidelines to appropriately monitor contamination in pharmacies and patient care area managers.</p>","PeriodicalId":16637,"journal":{"name":"Journal of Oncology Pharmacy Practice","volume":" ","pages":"10781552241307905"},"PeriodicalIF":1.0,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142864699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
