Abstract
The present invention provides for a method to monitor the health of a subject. The method includes obtaining a test sample from the patient. A first probe specific for a CpG promoter region of a biomarker selected from p16, MGMT, PAX-α, PAX5-β, RASSF1A, HLHP, GATA4, GATA5, SFRP1, LAMC2, IGFBP3, H-cadherin, BETA 3, HLHP, and DAPK is provided to the sample. The probe contacts the test sample. The DNA of interest from the test sample is isolated. A second stage probe specific for a second CpG promoter region of a biomarker selected from p16, MGMT, PAX-α, PAX5-β, RASSF1A, HLHP, GATA4, GATA5, SFRP1, LAMC2, IGFBP3, H-cadherin, BETA 3, HLHP, and DAPK is provided to the sample to form a second stage PCR product. The DNA is analyzed for hypermethylation of the promoter region for at least one of p16, MGMT, PAX-α, PAX5-β, RASSF1A, HLHP, GATA4, GATA5, SFRP1, LAMC2, IGFBP3, H-cadherin, BETA 3, HLHP, and DAPK. Hypermethylation of the promoter region of at least one of p16, MGMT, PAX-α, PAX5-β, RASSF1A, HLHP, GATA4, GATA5, SFRP1, LAMC2, IGFBP3, H-cadherin, BETA 3, HLHP, and DAPK is an indication that the subject is at increased risk of developing cancer for example, non small cell lung cancer.
