irinotecan/necrosis

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

OBJECTIVE Previous research in a rat glioma model has shown that the local intratumoral application of polymerbased drug-eluting beads (DEBs) loaded with doxorubicin or irinotecan suppress tumour growth and prolong survival. For translation into a clinical setting, the present experiment

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 The aim of our preliminary study was to compare the efficacy of drug-eluting beads preloaded with irinotecan (DEBIRI) vs drug-eluting beads preloaded with doxorubicin (DEBDOX) as second-line treatment of unresectable liver metastases from cholangiocarcinoma (CCA). METHODS In 2013, 10

BACKGROUND Irinotecan-loaded drug-eluting beads represent a novel drug delivery method that allows for the locoregional delivery of irinotecan to colorectal liver metastases (CRLM). The method has shown impressive response rates. However, the pathological response to this treatment has not

OBJECTIVE The purpose of this study was to study the pharmacokinetics of irinotecan injected intravenously, intra-arterially, or loaded onto a delivery platform. METHODS Fifty-four New Zealand White rabbits with VX2 liver tumor, divided in 3 groups of 17 rabbits, each received irinotecan either by

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

OBJECTIVE To assess the effect of irinotecan-eluting stents (IS) on neointimal growth in the aortas of hypercholesterolemic rabbits and to determine other local histopathological effects such as necrosis, fibrin, and inflammatory reaction. METHODS Phosphorylcholine-coated stents were deployed in the

OBJECTIVE To observe and evaluate the pathologic changes and curative effects of irinotecan (CPT-11), 5-fluorouracil (5-FU) and combined short-term radiotherapy before low-set rectal cancer operation so as to provide a theoretic basis for formulating a new effective adjuvant therapeutic

The present approach at our institution for the treatment of patients with colorectal (CRC) cancer and with liver metastases planned for metastasectomy is the neoadjuvant administration of Bevacizumab with Irinotecan based therapy. Metabolic imaging of tumor viability with 18F-fluorodeoxyglucose

OBJECTIVE To explore the effect of Shengjiang Xiexin Decoction (SXD) on the intestinal mucosal and functional cells of rats after irinotecan (CPT-11) chemotherapy. METHODS Totally 24 healthy Sprague-Dawley (SD) male rats were divided into three groups, the normal control group, the CPT-11 group, the
