UGT1A1 Gene Polymorphisms in Patients with Small Cell Lung Cancer Treated with Irinotecan-Platinum Doublet Chemotherapy and Their Association with Gastrointestinal Toxicity and Overall Survival.

ABSTRACT:

Background

Irinotecan (CPT11) is an important drug for small cell lung cancer (SCLC) chemotherapy (CTx). UDP-glucuronosyltransferase 1A1 (UGT1A1) polymorphisms can influence CPT11-related toxicity. This study aimed to assess prevalence of UGT1A1 polymorphisms and their association with clinical outcomes in patients with SCLC on CPT11-CTx.

Methods

An observational cohort of treatment-naïve patients with SCLC was given CPT11-platinum doublet at a referral center in North India over 3 years. Clinical outcomes assessed were hematological and gastrointestinal toxicity (Common Terminology Criteria for Adverse Events, version 3.0), response rates (RECIST), and overall survival (OS). Peripheral blood was drawn from all enrolled patients just prior to CPT11-CTx initiation, and genomi
