Promoter hypermethylation of RASSF1A and RUNX3 genes as an independent prognostic prediction marker in surgically resected non-small cell lung cancers

Aberrant methylation of promoter CpG islands is known to be a major inactivation mechanism of the tumor suppressor and tumor-related genes. Some published studies suggest a relationship to exist between the methylation status of several genes and the prognosis in non-small cell lung cancer (NSCLC); hypermethylation of the specific genes may be expected to serve as a biomarker for the prognosis, after a curative resection of NSCLC. To determine...
