We conducted a genome-wide association study (GWAS) to identify single nucleotide polymorphisms (SNPs) influencing overall survival (OS) of small-cell lung cancer (SCLC) patients. We prospectively collected blood samples from 139 SCLC patients who participated in phase II studies of irinotecan and cisplatin (IP) chemotherapy as first-line therapy. Among 334 127 SNPs, which passed quality control, seven showed significant association with OS. The rs16950650CT, rs7186128AG or GG, rs17574269AG, rs8020368CC, rs4655567CC, rs2166219TT or rs2018683TT showed shorter OS compared with control alleles. Among the seven SNPs, rs4655567, rs8020368 and rs2018683 were significantly associated with a resistant relapse (RR). In the multivariate analysis, rs8020368CC was significantly associated with higher risk of RR (odds ratio=16.7, P=0.007). In vitro and in silico analysis showed that SNPs in C14orf49 might be associated with epithelial-to-mesenchymal transition. This exploratory GWAS identified candidate SNPs that may be predictive of the clinical outcome of SCLC patients receiving IP.The Pharmacogenomics Journal advance online publication, 12 March 2013; doi:10.1038/tpj.2013.7.

Genetically determined cell membrane transporters and metabolic enzymes play a crucial role in the transportation of a wide variety of substrates that maintain homeostasis in biological processes. We ...
High maximum standardized uptake values on [(18)F]-fluoro-2-deoxyglucose positron emission tomography are associated with inferior survival in non-small cell lung cancer. Here, we investigated the bio...

Malignant neoplasm arising from the epithelium of the BRONCHI. It represents a large group of epithelial lung malignancies which can be divided into two clinical groups: SMALL CELL LUNG CANCER and NON-SMALL-CELL LUNG CARCINOMA.
A form of highly malignant lung cancer that is composed of small ovoid cells (SMALL CELL CARCINOMA).
An analysis comparing the allele frequencies of all available (or a whole GENOME representative set of) polymorphic markers in unrelated patients with a specific symptom or disease condition, and those of healthy controls to identify markers associated with a specific disease or condition.
A heterogeneous aggregate of at least three distinct histological types of lung cancer, including SQUAMOUS CELL CARCINOMA; ADENOCARCINOMA; and LARGE CELL CARCINOMA. They are dealt with collectively because of their shared treatment strategy.
A plant species of the family FABACEAE used to study GENETICS because it is DIPLOID, self fertile, has a small genome, and short generation time.
