Molecular findings in oral premalignant fields: update on their diagnostic and clinical implications.

Abstract excerpt

The development of multiple oral tumours, seen in up to 30% of patients with a primary oral squamous cell carcinoma, is sometimes attributable to the presence of genetically altered premalignant fields and has important prognostic implications. Molecular techniques available for the definitive diagnosis of such a field (loss of heterozygosity analysis of 3p, 9p and 17p and study of TP53 tumour suppressor gene...
