  • Response rate [ Time Frame: Every 6 weeks, an expected average of 6-8 months. ]
    Association between UGT1A1 polymorphism, CPT-11 dosage and tumor response.
  • Progression-free survival (PFS) [ Time Frame: An expected average of 6-8 months. ]
    Association between UGT1A1 polymorphism, CPT-11 dosage and PFS. PFS is defined as the length of time from randomise to disease progression or to death from any cause other than progression.
  • Pharmacokinetics of irinotecan and its metabolites, SN-38 and SN-38G. [ Time Frame: The first treatment cycle. ]
    Association between UGT1A1 polymorphism, CPT-11 dosage and pharmacokinetics of irinotecan. Plasma concentration of irinotecan and its metabolites, SN-38 and SN-38G are determined using high-performance liquid chromatography-tandem mass spectrometry method (HPLC-MS/MS).
  • Association between UGT1A1 polymorphism and irinotecan pharmacokinetics [ Time Frame: First 3 days from the treatment beginning ]
    Determine human plasma concentrations of irinotecan and its metabolites, SN-38, SN-38G, using high-performance liquid chromatography with fluorescence detector (HPLC-FLD)
  • Progression-free survival [ Time Frame: an expected average of 6 months ]
    PFS is defined as the length of time from randomise to disease progression of or to death from any cause other than progression.

Individual Dosage Selection of Irinotecan (CPT-11) Based on UGT1A1 Genotype in Metastatic Colorectal Cancer Patients
Influence of Individual Dosage Selection of Irinotecan (CPT-11) Based on UGT1A1 Genotype on Clinical Outcomes and Pharmacokinetics in Chinese Patients With Metastatic Colorectal Cancer
The purpose of this study is to investigate the influence of dose selection of CPT-11 on toxicity, response and pharmacokinetics according to UGT1A1 genotype in colorectal cancer patients.

Genetic polymorphisms of UGTs result in reduced enzyme activity and increased toxicity. UGT1A1*28 and UGT1A1*6 are reported to increase CPT-11-related toxicity in Asian patients. Moreover, the area under concentration curve (AUC) ratio of SN-38G to SN-38 is decreased in Asian patients having UGT1A1 *28 or UGT1A1*6. This implicated that the current standard dose of CPT-11 would be overdosing for homozygous UGT1A1*28/*28, *6/*6 or *28/*6 patients.

The study is designed to investigate the role of prospectively dose reduction of CPT-11 in toxicity, tumor response and pharmacokinetics for homozygous UGT1A1 patients, and compare these parameters to standard dose of CPT-11 for wild-type, heterozygous or homozygous UGT1A1 patients.
