RESUMO
OBJECTIVE: To investigate the correlation between clinicopathological features and BRAF~(V600E) gene mutation in papillary thyroid carcinoma(PTC). METHODS: The data of 290 cases of PTC admitted from August 2016 to May 2018 in Beijing Tongren Hospital,Capital Medical University were analyzed retrospectively. All the cases of PTC were examined by BRAF~(V600E) immunohistochemistry after operation. Mutation positive group included 192 cases. Mutation negative group included 59 cases and partial mutation group included 39 cases. The cases of partial mutantion were excluded. The clinicopathological differences between the two groups were compared. RESULTS: By statistical analysis,there was a statistical difference between two groups in the invasion of the capsule(P<0.05). In the two groups(microcarcinoma and non-microcarcinoma),there was the same result.There was no statistical difference in other indexes. CONCLUSION: In patients with PTC,BRAF~(V600E) gene mutation is not associated with the clinicopathological features of the PTC. Patients with non-BRAF~(V600E) gene mutations are more likely to invade the membranes of microcarcinomas and non-microcarcinomas.
