DNA Methylation in Serum and Tumors of Cervical Cancer Patients

Abstract

To the best of our knowledge, this is, thus far, the largest study investigating aberrant promoter hypermethylation in serum samples from cancer patients and the first study investigating methylation patterns in sera of cervical cancer patients. Our results suggest that serological detection of MYOD1 promoter hypermethylation may be of potential use as a prognostic marker for discriminating cervical cancer patients at high risk for lymph node metastasis or relapse. Additional studies, including a panel of additional genes, are necessary to elucidate the role of aberrant methylation in serum as a tool for surveillance of cervical cancer.
