Primary Outcome Measures:
  • Association between UGT1A1 polymorphism and incidence of neutropenia and diarrhea [ Time Frame: From first 2 weeks to the whole treatment period, an expected average of 6 months ] [ Designated as safety issue: Yes ]
    Incidence and grade of neutropenia and diarrhea are record in the whole treatment duration according to NCI-CTC AE 3.0 version


Secondary Outcome Measures:
  • Association between UGT1A1 polymorphism and irinotecan pharmacokinetics [ Time Frame: First 3 days from the treatment beginning ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
    PFS is defined as the length of time from randomise to disease progression of or to death from any cause other than progression.

  • Response rate [ Time Frame: every 6 weeks,an expected average of 6 months ] [ Designated as safety issue: No ]
    According to RECIST criteria

Arms Assigned Interventions
Active Comparator: homozygous UGT1A1*1
CPT-11(Irinotecan ) 180 mg/m2 90-minute i.v. infusion on day 1; leucovorin 400mg/m2 i.v. infusion on day 1 ; followed by 5-FU 400mg/m2 i.v. bolus on day 1, then 2400mg/m2 i.v. over 46 hours continuous infusion; repeat every two weeks.
Drug: CPT-11
CPT-11 will be administered according to UGT1A1 genotypes, while the doses of infusional 5-FU/LV will remain the standard dose.
Other Name: irinotecan
Active Comparator: UGT1A1*1/*28 or UGT1A1*1/*6
CPT-11(Irinotecan ) 180 mg/m2 90-minute i.v. infusion on day 1; leucovorin 400mg/m2 i.v. infusion on day 1 ; followed by 5-FU 400mg/m2 i.v. bolus on day 1, then 2400mg/m2 i.v. over 46 hours continuous infusion; repeat every two weeks.
Drug: CPT-11
CPT-11 will be administered according to UGT1A1 genotypes, while the doses of infusional 5-FU/LV will remain the standard dose.
Other Name: irinotecan
Experimental: UGT1A1*28/*28 or*6/ *6 or *28/*6
CPT-11(Irinotecan ) 90 mg/m2 90-minute i.v. infusion on day 1; leucovorin 400mg/m2 i.v. infusion on day 1 ; followed by 5-FU 400mg/m2 i.v. bolus on day 1, then 2400mg/m2 i.v. over 46 hours continuous infusion; repeat every two weeks.
Drug: CPT-11
CPT-11 will be administered according to UGT1A1 genotypes, while the doses of infusional 5-FU/LV will remain the standard dose.
Other Name: irinotecan

Detailed Description:

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 UGT1A1 *28 or UGT1A1 *6 genotype patients.
