Significant progress has recently been made in the clinical management of papillary thyroid carcinoma. The accuracy of diagnosis and prognostic stratification of this type of carcinoma are high but still fall below 100%. Lack of effective treatments for advanced stage papillary thyroid carcinoma leads to death in some patients. Approximately half of all such carcinomas harbor mutations in the gene encoding the serine/threonine-kinase B-type Raf kinase (BRAF), resulting in constitutive activation of the mitogen-activated protein kinase-extracellular-signal-regulated kinases signal transduction pathway. There is intriguing evidence that BRAF mutation testing of papillary thyroid carcinoma might improve the diagnosis, prognostic stratification and treatment of these tumors but large, prospective trials are needed to define the actual clinical impact of these approaches.

Abstract
Significant progress has recently been made in the clinical management of papillary thyroid carcinoma. The accuracy of diagnosis and prognostic stratification of this type of carcinoma are high but still fall below 100%. Lack of effective treatments for advanced stage papillary thyroid carcinoma leads to death in some patients. Approximately half of all such carcinomas harbor mutations in the gene encoding the serine/threonine-kinase B-type Raf kinase (BRAF), resulting in constitutive activation of the mitogen-activated protein kinase-extracellular-signal-regulated kinases signal transduction pathway. There is intriguing evidence that BRAF mutation testing of papillary thyroid carcinoma might improve the diagnosis, prognostic stratification and treatment of these tumors but large, prospective trials are needed to define the actual clinical impact of these approaches.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
