In multiple studies of metastatic colorectal cancer,uridine diphosphate glucuronosyl transferase 1A1(UGT1A1) gene polymorphisms and its correlation with irinotecan-associated side effects have been confirmed.Data from several studies indicated an improved clinical outcome of patients who had received an irinotecan-based regimen.In order to find out the correlation between UGT1A1 gene polymorphisms and the side effect and efficacy of irinotecan in patients with small cell lung cancer,we designed this study.
The purpose of this study is to find out the correlation between uridine diphosphate glucuronosyl transferase 1A1(UGT1A1) gene polymorphisms and the side effect and efficacy of irinotecan in patients with small cell lung cancer.
