Here we test the hypothesis that specific candidate gene methylation markers (CCNA1, NDN, CD1A, DCC, GADD45a, and p16) are associated with tumor recurrence and survival, in a well-characterized, prospective cohort of HNSCC patients with extensive epidemiologic, clinical and outcome information, who were treated by a single group of clinicians with a homogenous treatment approach. Here, CCNA1 is linked to neoplasm.
