However, in agreement with our results it has been previously described that high frequencies of iNKT cells, and more importantly high frequencies of interferon gamma-producing iNKT cells are correlated with tumor surveillance and increased survival in non-small cell lung cancer patients, and an adjuvant effect iNKT cells appears to be a determinant for tumor eradication [19], [20]. The gene discussed is IFNG; the disease is neoplasm.
