These findings suggested that SNPs rs71428439 (miR-149), rs2910164 (miR-146a), rs928508 (mir-30c-1) and rs629367 (let-7a-2) were associated with the lung cancer prevalence, polymorphisms of rs11614913 (miR-196a-2) and rs9280508 (miR-30c-1) significantly influenced the patients' response to platinum-based chemotherapy, which may serve as potential clinical biomarkers to predict lung cancer risk and platinum-based chemotherapy response.
However, miR-196a2 rs11614913, miR-30c-1 rs928508, miR-608 rs4919510 and miR-27a rs895819 polymorphisms were not significantly associated with lung cancer risks in any models.
