ABSTRACT

The occupational exposure of caregivers to antineoplastic agents has been demonstrated since 1979. Since the early 1990s, numerous studies from several countries have demonstrated the contamination of care facilities by antineoplastic drugs. As it is easier to sample, most contamination measurements in workers are carried out in urine sample. The distribution and elimination half-lives of irinotecan suggest that blood can be considered as better than urine for the biomonitoring of a potential contamination of healthcare workers. We describe here the development and the validation of a UHPLC-MS/MS method to simultaneously quantify irinotecan, and two of its main metabolites, APC and SN-38, at ultra-trace levels in plasma and red blood cells (RBC). This method has been applied to blood samples collected from several healthcare services in a French comprehensive cancer center. The results demonstrate that the method is sensitive enough to identify a contamination of healthcare workers by irinotecan and SN-38 at very low concentrations. Moreover, the results show that analysis of RBC is of great interest and complementary to that of serum.

ABSTRACT

BACKGROUND: Antineoplastic drug exposure is a major problem in regard to caregivers' health. The aim of the present study was to assess the perception, knowledge, and handling practices of all occupation level categories of two oncology day hospitalization units and two compounding units regarding the risk of exposure to antineoplastic drugs. METHODS: This descriptive study, performed through face-to-face interviews, concurrently assessed the perception, knowledge, and handling practices of antineoplastic drugs in five different job categories in four different settings. This work was part of a larger comprehensive project examining surface and blood contamination. Different scores were assigned to evaluate responses to a questionnaire about the perception, knowledge, and handling practices of healthcare workers, a risk global score including a risk perception score, and education/knowledge and handling practices scores. RESULTS: In the survey, continuous training was associated with the global risk score (p = 0.03), particularly with the handling practices risk score (p = 0.01). Job category was also significantly associated with the global risk score (p < 0.001), particularly with the handling practices risk score (p < 0.001) and the education/knowledge score (p < 0.001). Pharmacy technicians had the highest score regarding risk perception (71.4%), indicating a higher perception of risk, and had a lower score regarding handling practices (25.0%) as well as a lower score (15.7%) regarding risk knowledge. Nurses and physicians had a high score (50%) regarding the risk of handling practices and a score of 57.1% regarding risk perception, indicating an increased perception of safety. Auxiliary caregivers had the highest global score (43.5%) and a score of 30.0% regarding handling practices. CONCLUSIONS: This study identified significant differences among healthcare workers depending on job categories in the antineoplastic drug handling practices and in the knowledge of the risks associated with occupational exposure to antineoplastic drugs. These differences were particularly important between trained and untrained participants, revealing the importance of implementing a continuous training program.

ABSTRACT

OBJECTIVES: Hyperthermic intraperitoneal chemotherapy (HIPEC) is a beneficial surgical technique for patients, but the surgeons are being exposed to cytotoxic drugs. Few biomonitoring studies were led on blood samples in the context of HIPEC. This study aimed to evaluate the surgeon's plasmatic and red blood cell (RBC) contamination by irinotecan, two of its major metabolites and platinum compounds. METHODS: HIPEC procedures performed using the coliseum techniques were observed between September 2015 and April 2018 in a French comprehensive cancer center. Irinotecan and its metabolites SN-38 and APC were dosed by UHPLC with a limit of quantification determined at 50 pg/mL. Platinum compounds were dosed by inductively coupled plasma mass spectrometry with a limit of quantification determined at 16 pg/mL. RESULTS: Despite collective and personal protective equipment, 80% of plasma samples were contaminated by irinotecan and 33% by platinum compounds out of 21. The results showed that the surgeon was contaminated after HIPEC and even after a period of HIPEC inactivity. Nineteen percent of plasmatic samples and 45% of RBC samples were contaminated by SN-38, the active metabolite of irinotecan. APC was only found in some RBC samples (33%). CONCLUSIONS: Even if this study shows blood contamination by irinotecan, two of its major metabolites (including active SN-38) and platinum compounds both in the plasma and RBC of a surgeon performing the HIPEC procedures, further studies should be performed to confirm these results. Additional studies should be carried out to further investigate the contamination in the context of HIPEC and more broadly in the hospital.

ABSTRACT

BACKGROUND: During hyperthermic intraperitoneal chemotherapy (HIPEC), caregivers are exposed by different routes to cytotoxic drugs. This review proposes an overview of the safety of HIPEC by assessing existing data on protection procedures, biological and non-biological samples. Based on these data, relevant good practices, eventual irrelevant overprotection procedures and missing data to implement adapted protections are highlighted. MATERIALS AND METHODS: Data were extracted from a systematic review of literature from 1980 till 2016: number and type of surgical procedure, healthcare professionals present, protective equipment, samples, pre-analytical method and analytical method. RESULTS AND DISCUSSION: Only 55 HIPEC procedures have been evaluated. The majority of antineoplastic drugs used have all required characteristics to penetrate the organism and are recognized as very dangerous. Moreover, a great heterogeneity in protective equipment used, either individual or collective is observed. Environmental contamination occurs during HIPEC, especially for all surfaces in the operating room. Compounds penetration into caregivers lungs cannot be excluded. Priority remains to prove professionals contamination by focusing on biological samples. Biological material is rarely sampled or samples are not necessarily adapted. CONCLUSION: Repeated blood tests should be preferred using appropriate sampling schedules and validated sensitive analytical methods. Furthermore, there is a great need of new biological indicators to monitor caregivers exposure. During hyperthermic intraperitoneal chemotherapy (HIPEC), healthcare workers are exposed by different routes to cytotoxic drugs. There are currently few available occupational exposure data and environmental monitoring and biomonitoring must be improved in order to ensure optimal protection against antineoplastic drugs.
