Methylation Array Analysis of Preoperative and Postoperative Saliva DNA in Oral Cancer Patients

Abstract

We report methylation array analysis of 807 cancer-associated genes in the saliva of oral cancer patients before and after oral cancer resection. Our methylation biomarker approach shows the proof of principle that methylation array analysis of saliva can produce a set of cancer-related genes that are specific and can be used as a composite biomarker for the early detection of oral cancer.
