Does equipment change impact blood contamination with irinotecan and its two major metabolites in a centralized cytotoxic pharmacy unit?

Abstract : Background Antineoplastic drugs exposure is a major problem for caregivers’ health. The aim of this study is to assess blood contamination with irinotecan and its two metabolites in a centralized pharmacy unit for cytotoxic drug preparations workers before and after protective equipment changes. Methods The study took place in a university hospital centralized pharmacy unit for cytotoxic drug and was performed in two parts, before (Round 1: R1) and after equipment changes (Round 2: R2). Collection of pharmacy staff blood samples was performed in UHPLC-MS/MS. Plasma and red blood cell irinotecan and its metabolites (SN38; APC) were determined with a validated analytical method detection test. Results A total of 15/36 (41.6%) assays were positive in R1 and 16/72 (22.2%) in R2 with a significant decrease between periods ( P = 0.035). For plasma dosages, no difference between the two periods was found ( P = 0.71); respectively 4/18 (22.2%) assays were positive in R1 and 6/36 (16.6%) in R2. For red blood cells dosages, a significant decrease between periods was found ( P = 0.01); respectively 11/18 (61%) were positive in R1 and 10/36 (27.8%) in R2. Conclusions These dosages make it possible to have the very first evaluation for plasma and red blood cell contamination with irinotecan and its metabolites in the context of equipment changes, both at individual and collective levels. This work would help to protect health workers from the potential risks represented by these molecules, especially by revealing a contamination of workers in order to objectify the results of exposure.
