    Abstract:
    INTRODUCTION: Molecular markers are increasingly being explored as a potential diagnostic and prognostic tool in patients with well-differentiated thyroid cancers and B-type Raf kinase (BRAF) V600E mutation has received a wide attention in this regard. Many clinical studies have demonstrated an association of BRAF V600E mutation with aggressive clinicopathologic characteristics and high tumor recurrence and mortality in patients with papillary thyroid cancers. Papillary thyroid cancers has been abbreviated and PTCs. AIM: The present single center study aims to assess the biological behavior of conventional papillary thyroid cancers. (PTC) with somatic BRAF V600E mutation. MATERIALS AND METHODS: Patients who were managed for well differentiated thyroid cancers during 2005-2006 were included in the study. BRAF V600E mutation analysis was done by real time polymerase chain reaction after extracting genomic DNA from the representative archived formalin fixed paraffin embedded tumor tissue. RESULTS: Of the 79 patients of well-differentiated thyroid cancers included in the study, 31% harbored BRAF V600E mutation; the mutation prevalence was 39.6% in the cohort of conventional PTCs. Our study emphatically states that BRAF V600E mutation status is a significant predictor of adverse outcomes in patients with conventional PTCs. CONCLUSION: Our study further suggests a possible risk-stratified approach using age, BRAF V600E mutation status, and extrathyroidal spread, and this approach can be used to personalize the management of patients with conventional PTCs. The result of our study adds to the growing consensus that BRAF V600E mutational status should be analyzed in correlation with other molecular and clinicopathological prognostic factors for a better risk stratification.
