Irinotecan (CPT-11) has been reported to be cytotoxic to tumor cells through its inhibitory activity on type I DNA topoisomerase. CPT-11 has also been shown to have several unique biological activities apart from direct cytotoxicity. We investigated the ability of CPT-11 to induce tumor necrosis

Dose-limiting diarrhea and myelosuppression compromise the success of irinotecan (7-ethyl-10-[4-[1-piperidino]-1-piperidino]carbonyloxycamptothecin) (CPT-11)-based chemotherapy. A recent pilot study indicates that thalidomide attenuates the toxicity of CPT-11 in cancer patients. This study aimed to

Irinotecan, a topoisomerase I inhibitor, is clinically used as an anticancer drug. The present study investigated the anticancer effect of irinotecan on p53-negative Caco-2 and p53-positive CW2 human colorectal cancer cell lines. Cell viability for both Caco-2 and CW2 cells was little affected by

Interactions between the topoisomerase I inhibitor irinotecan (CPT-11) and the platinum derivative oxaliplatin (L-OHP) were investigated in HT29 colon cancer cell line. Synergism was observed when cells were simultaneously exposed to drugs or when cells were first exposed to CPT-11. Flow cytometric

For characterization of the mechanism(s) of severe diarrhea due to the anticancer agent, irinotecan hydrochloride (CPT-11), examination was made of the relation of CPT-11-related diarrhea to colonic prostaglandin E2 (PGE2) and water absorption in rats. Acute diarrheal symptoms were observed within 1

OBJECTIVE To investigate the pharmacokinetics and chemoembolization efficacy of irinotecan-loaded QuadraSphere microspheres (QSMs) in a rabbit VX2 liver tumor model. METHODS Fourteen rabbits with VX2 liver tumors were divided into two groups. In the irinotecan-loaded QSM group (n = 7), 3 mg of QSMs
