RED MEAT, MICRONUTRIENTS AND ORAL SQUAMOUS CELL CARCINOMA OF ARGENTINE ADULT PATIENTS.

Introduction: the identification of risk group of oral cancer allows reducing the typical morbidity and mortality rates of this pathology.

Objetive: it was analyzed the role of red meat, macronutrients and micronutrients on Oral Squamous Cell carcinoma (OSCC) in a case-control study carried out in Cordoba, Argentina.

Methods: case-control study 3:1, both genders, aged 24-80 years.

Nitric oxide synthase 2 (NOS2) expression in histologically normal margins of oral squamous cell carcinoma.

Unlabelled: The activity of Nitric Oxide Synthase 2 (NOS2) was found in oral squamous cell carcinomas (OSCC) but not in normal mucosa. Molecular changes associated to early carcinogenesis have been found in mucosa near carcinomas, which is considered a model to study field cancerization. The aim of the present study is to analyze NOS2 expression at the histologically normal margins of OSCC.
