The prognostic implication and potential role of BRAF mutation in the decision to perform elective neck dissection for thyroid cancer

The BRAF V600E mutation is the most common genetic change in patients with papillary thyroid cancer (PTC). Many studies have shown that detection of the BRAF V600E mutation is useful for confirming or establishing the preoperative diagnosis of PTC. Moreover, the mutation is associated with aggressive tumor characteristics or poor prognostic factors in most. However, whether preoperative detection of this mutation changes the treatment strategy or surgical extent, including prophylactic central neck dissection (CND), remains controversial. In this paper, we review the currently available literature regarding the potential role of the BRAF V600E mutation in the decision to perform elective neck dissection for PTC.
