RESUMEN
Occupational exposure of anticancer agents during their preparation has been recognized as a serious hazard. Closed system drug transfer devices (CSTDs) enable "safe" preparation of agents for medical personnel and ensure a safe hospital environment. However, artificial particles of infusion materials have been reported during CSTD use. Here, the incidence of insoluble fine particles during preparation of anticancer agents using CSTDs was examined. Visible insoluble fine particles were found in 465 (9.4%) of 4948 treatment cases at Ehime University Hospital with CSTD use. Contaminants occurred more frequently during preparation of monoclonal antibodies than cytotoxic anticancer agents (19.4% vs. 4.1%, respectively, P < 0.01). A similar survey was conducted at nine hospitals to investigate the incidence of insoluble fine particles with or without CSTDs. Insoluble fine particles were detected in 113 (15.4%) of 732 treatment cases during preparation of monoclonal antibodies with CSTD use. In contrast, the occurrence of insoluble fine particles without CSTDs was found in only 3 (0.073%) of 4113 treatment cases. Contamination with CSTDs might cause harmful effects on patients during cancer therapy. We strongly recommend the use of in-line filters combined with infusion routes after CSTD use to avoid contamination-associated adverse events.

The safety of docetaxel (60 mg/m(2)) plus cyclophosphamide (600 mg/m(2)) every three weeks (TC) as adjuvant therapy for Japanese women with operable breast cancer was evaluated. Ehime TC Study Group initiated the randomized control study,which compared the effects of the TC course number (4 cycles versus 8 cycles) in the adjuvant setting on the treatment outcomes of breast cancer patients. Eight patients were investigated on the side effects of TC therapy, four of them were allocated to 4 cycles of TC, and four to eight cycles from May, 2004 to Feb. 2005. Leukocytopenia and neutropenia of grade 3 or 4 were seen in 50% and 63% of the cases, respectively. No febrile neutropenia was seen. Although the non-hematological side effects of grade 3 or 4 were not observed, alopecia, stomatitis, skin toxicities and edema of grade 2 were seen in 100%, 25%, 25%, 13% of cases, respectively. TC therapy was well tolerated. All anticancer drugs could be administered as scheduled. From these preliminary results, TC therapy seems to be able to be safely prescribed postoperatively for Japanese women operated for breast cancer.
