Association of Wnt-Inducible Signaling Pathway Protein 1 Genetic Polymorphisms With Lung Cancer Susceptibility and Platinum-Based Chemotherapy Response

Abstract Background Platinum-based chemotherapy is the main treatment method for lung cancer patients. The genetic polymorphisms of Wnt-inducible signaling pathway protein 1 ( WISP1 ) were reported to be associated with the development of diverse lung diseases. In this study, we aimed to investigate the relationship of WISP1 genetic polymorphisms with lung cancer susceptibility and platinum-based chemotherapy response in Chinese lung cancer patients. Materials and Methods A total of 556 lung cancer patients and 254 healthy controls were enrolled onto this study. The 28 polymorphisms of the WISP1 gene were genotyped by the Sequenom MassARRAY system. Results We found that WISP1 rs16893344, rs2977530, rs2977537, and rs62514004 ( P  = .009, .033, .049, and .036, respectively) polymorphisms were related to susceptibility of lung cancer; and WISP1 rs11778573 ( P  = .023, nonsmokers), rs16893344 ( P  = .013, ≥ 50 years old), rs2977536 ( P  = .039, ≥ 50 years old; P  = .044, nonsmokers; P  = .047, non–small-cell lung cancer, respectively), rs2977549 ( P  = .013, smokers), and rs62514004 ( P  = .033, ≥ 50 years old) polymorphisms were significantly associated with platinum-based chemotherapy response in lung cancer patients. Conclusion Genotypes of WISP1 may be novel and useful biomarkers for diagnosis of lung cancer and evaluation of platinum-based chemotherapy response in lung cancer patients.
