Oral Carcinogenesis and Oral Cancer Chemoprevention : A Review

Abstract EN

Oral cancer is one of the major global threats to public health.

The development of oral cancer is a tobacco-related multistep and multifocal process involving field cancerization and carcinogenesis.

The rationale for molecular-targeted prevention of oral cancer is promising.

Biomarkers of genomic instability, including aneuploidy and allelic imbalance, are possible to measure the cancer risk of oral premalignancies.

Understanding of the biology of oral carcinogenesis will yield important advances for detecting high-risk patients, monitoring preventive interventions, and assessing cancer risk and pharmacogenomics.

In addition, novel chemopreventive agents based on molecular mechanisms and targets against oral cancers will be derived from studies using appropriate animal carcinogenesis models.

New approaches, such as molecular-targeted agents and agent combinations in high-risk oral individuals, are undoubtedly needed to reduce the devastating worldwide consequences of oral malignancy.
