The results from Eilertsen et al. [69] are in agreement with those reported by Guo et al. [78], which describe that a single nucleotide polymorphism (SNP) of the MCT1 gene (TT genotype of SNP rs1049434) was associated with better OS and RFS of NSCLC patients. The gene discussed is SLC16A1; the disease is non-small cell lung carcinoma.
