Objective To investigate whether Hashimoto’s thyroiditis affects the sonographic features of papillary thyroid carcinoma(PTC) and its relationship with its invasiveness and BRAF
V600E
mutations.Methods A total of 158
pa
tients with positive PTC were divided into HT group and non-HT group(79 cases in each group).The features of conventional ultrasound and contrast-enhanced ultrasound
elastography
invasiveness and BRAF
V600E
mutations were compared between the two groups.Binary Logistic regression was used to analyze the correlation between ultrasound features and BRAF
V600E
mutations.Results The proportion of female patients in HT group was higher than that in non-HT group(P
<
0.05).There were no significant differences between the two groups in ultrasonic features(boundary of lesion
aspect ratio
microcarcinoma
microcalcification
number of lesion
cervical lymph node metastasis)
contrast-enhanced ultrasound mode and elastography scores.Among 158 cases
18 cases invaded the surrounding tissues
5 cases in HT group and 13 cases in non-HT group.135 cases were BRAF
V600E
mutations positive
63 cases in HT group and 72 cases in non-HT group
the differences were statistically significant(all P
<
0.05).In 135 BRAF
V600E
mutations positive cases
there was no significant difference in lymph node metastasis between the two groups
but there was significant difference in invasion(P
<
0.05).In 158
pa
tients with PTC
BRAF
V60 E
mutations was positively correlated with microcarcinoma and aspect ratio

both P

and BRAF
V600E
mutations was positively correlated with microcarcinoma in HT group(OR=3.590
P
<
0.05).Conclusions PTC with HT is more common in women.The presence of HT can not affect the sonographic features of PTC
the invasiveness of PTC with HT and the mutation rate of BRAF
V600E
gene are lower than that of PTC.In PTC
the mutations of BRAF
V600E
is related to microfocus

1.Mutations of BRAF
V600E
gene in PTC with HT are associated with microlesions.
