SNPs in PI3K-PTEN-mTOR and Brain Metastases in NSCLC—Response

We thank Giovannetti and colleagues for their thoughtful comments about our recent article ([1][1]) entitled “Associations between Single-Nucleotide Polymorphisms in the PI3K-PTEN-AKT-mTOR Pathway and Increased Risk of Brain Metastasis in Patients with Non–Small Cell Lung Cancer.” In their
