This study aims at establishing relationships between genetic and non-genetic factors of variation of the pharmacokinetics of irinotecan and its metabolites; and also at establishing relationships between the pharmacokinetic or metabolic parameters and the efficacy and toxicity of irinotecan. We included 49 patients treated for metastatic colorectal cancer(More)
INTRODUCTION Glutathione S-transferase P1 (GSTP1) and excision-repair cross-complementing repair deficiency group 2 protein (ERCC2 or XPD) may modulate the activity of platinum derivatives. The SNPs, Ile105Val for GSTP1 and Lys751Gln for ERCC2, may affect the efficiency of oxaliplatin in patients treated with an oxaliplatin-based regimen for metastatic(More)
Carboxylesterase 2 (CES2) is involved in the activation of the anticancer drug irinotecan to its active metabolite SN-38. We previously identified a single nucleotide polymorphism (SNP), with an allele frequency around 10%, as possibly involved in enzyme expression (Clin Pharmacol Ther 76:528–535, 2004), which could explain the large individual variation in(More)
Doxorubicin (dox) encapsulated in polyisohexylcyanoacrylate nanospheres (PIHCA-dox) can circumvent P-glycoprotein-mediated multidrug resistance (MDR). In order to investigate whether this drug formulation is able to select MDR cells in culture in the same way as free doxorubicin does, two human tumour cell lines, K562 and MCF7, were grown with increasing(More)
BACKGROUND The objective of this study was to determine whether specific single nucleotide polymorphisms (SNPs) from nucleotide excision repair (NER) and homologous recombination (HR) DNA repair pathways are associated with sensitivity to trabectedin in patients with soft tissue sarcoma (STS). METHODS The authors analyzed excision repair(More)
The aim of this study was to improve significantly the sensitivity and specificity of the flow cytometric assay of P-glycoprotein (Pgp) implemented and validated by the laboratories of the French Drug Resistance Network [Huet S, Marie JP, Gualde N, Robert J.
