Evaluation of the Role of Trace Elements in Malignant Transformation of Oral Submucous Fibrosis: A Study in the Population of Krishna District, Andhra Pradesh, India

TL;DR

This study explores how trace elements like copper and zinc may be linked to cancer development in a condition called oral submucous fibrosis among people in Krishna District, India.

Contribution

The study identifies elevated serum copper and zinc levels as potential indicators of malignant transformation in oral submucous fibrosis.

Findings

Serum copper levels were significantly higher in malignant-transformed OSMF cases compared to controls.

Zinc levels also showed significant elevation in malignant-transformed OSMF cases.

Iron and selenium levels did not differ significantly across groups.

Abstract

Introduction: Oral submucous fibrosis (OSMF) is a chronic, potentially malignant disorder linked predominantly to areca nut chewing. This study investigates the role of serum trace elements (Cu, Fe, Zn, Se) in the progression and malignant transformation of OSMF.

Methodology: A community-based cross-sectional study involved 80 participants from the Government Dental College, Vijayawada, Krishna District, AP. Participants were divided into four groups: areca nut users without OSMF, areca nut users with OSMF, areca nut users with malignant-transformed OSMF, and healthy controls. Blood samples were analyzed for serum iron, copper, zinc, and selenium levels.

Results: Significant differences were found in serum copper (P=0.032) and zinc levels (P=0.006), with elevated levels observed in the malignant-transformed OSMF group compared to controls. No significant differences were observed in serum iron (P=0.542) and selenium levels (P=0.062) across the groups.

Conclusion: Elevated serum copper levels can serve as a reliable diagnostic marker for malignant transformation in OSMF. Future research should explore the potential therapeutic benefits of copper chelation in OSMF management.
