ObjectiveTo discuss the correlation of BRAFV600E mutation with clinicopathologic characteristics or thyroglobulin (Tg) in papillary thyroid carcinoma (PTC) and its clinical significance. MethodsThe BRAFV600E mutations of 55 patients with PTC were detected by nested PCR. The relations between BRAFV600E mutation and the clinicopathologic characteristics were analyzed. Results①The BRAFV600E mutations happened in 29 patients with PTC, the mutation rate was 52.7% (29/55).②The BRAFV600E mutation rate was related with extracapsular spread, multiple lesions, regional lymph node metastasis or average Tg value > 1.0μg/L during 2 years after standardized treatment (P value was 0.01, 0.02, 0.02, 0.03, respectively), but which not related with the gender, age, tumor diameter, or TNM stage (P > 0.05). ConclusionThe BRAFV600E mutation in PTC might lead to increased tumor aggressiveness and it might be related with increased Tg value after standardized treatment.
