BRAF p.V600E Mutation Shows Limited Prognostic Value in Papillary Thyroid Cancer Risk Stratification
- A new study of 301 papillary thyroid carcinoma patients found that BRAF p.V600E mutation, present in 78.7% of cases, does not significantly predict disease recurrence when other clinical factors are considered.
- Multivariate analysis identified large-volume lymph node metastasis and male gender as the only significant predictors of recurrence, while BRAF p.V600E showed no association with increased recurrence risk.
- Despite limited prognostic utility, BRAF p.V600E testing remains clinically important for identifying patients who may benefit from targeted BRAF inhibitor therapies in aggressive or radioactive iodine-refractory cases.
