Oral field cancerization: current evidence and future perspectives

Area of Science:

• Oncology
• Oral Medicine
• Cancer Biology

Background:

• Oral field cancerization posits that oral cancer arises from a field of susceptible cells, not isolated events.
• This phenomenon explains multifocal cancer development and is linked to carcinogens like tobacco.
• It is a key concept for understanding multiple primary oral cancers and post-excision recurrences.

Purpose of the Study:

• To review the origin and principles of oral field cancerization.
• To explore theories explaining this effect.
• To discuss molecular, genetic, cytogenetic, clinical implications, and future research.

Main Methods:

• Literature review of oral field cancerization.
• Analysis of molecular, genetic, and cytogenetic findings.
• Discussion of clinical relevance and research directions.

Main Results:

• The review details the underlying mechanisms and theories of oral field cancerization.
• It synthesizes current molecular, genetic, and cytogenetic evidence.
• Clinical implications and future research avenues are identified.

Conclusions:

• Oral field cancerization is a critical concept in understanding oral cancer multifocality.
• A comprehensive understanding requires integrating molecular, genetic, and clinical perspectives.
• Further research is needed to refine understanding and improve patient outcomes.
