Risk Assessment Of Cervical Lymph Node Metastasis In Papillary Thyroid Carcinoma With Different Echogenicity

Objective: The study explored the risk of cervical lymph node metastasis of different echo types of Papillary Thyroid cancer(PTC),and provided a reference for ultrasound assessment of the risk of cervical lymph node metastasis of PTC.Methods: Using retrospective research methods,the study and analysis of the ultrasound data and pathological data of 528 patients with PTC who underwent surgery and pathology in our hospital from December2019 to January 2020 were carried out.Each patient underwent cervical lymph node dissection and had lymph nodes.Pathological results.Divide 528 cases of PTC into cervical lymph node metastasis group and non-neck lymph node metastasis group.According to the type of PTC echo,they are divided into markedly hypoechoic,hypoechoic,other echoes(isoechoic,hyperechoic,mixed echo),and cervical lymph node metastasis group : 136 men and 61women;116 cases of <45,81 cases of ≥45;62 cases of markedly hypoechoic,123 cases of hypoechoic,12 cases of other echoes;no cervical lymph node metastasis group: 271 men,60 females;158 cases of <45,173 cases of ≥45;60 cases of markedly hypoechoic,245 cases of hypoechoic,26 cases of other echoes.Results:(1)The difference between the PTC metastasis group with different echo types and the non-metastatic group is statistically significant(P<0.05).The transfer rate of markedly hypoechoic patients is higher than that of hypoechoic patients and other echoes,and the transfer rate of hypoechoic patients is slightly higher than that of other echoes.(2)There was a statistically significant difference in gender and age between the metastatic group and the non-metastatic group(P<0.05),men are more likely to metastasize than women,and those less than 45 are more likely to metastasize than those ≥45.Conclusion: The risk of cervical lymph node metastasis in markedly hypoechoic PTC is higher than that of hypoechoic and other types of echo.Men are more likely to metastasize than women,and those less than 45 are more likely to metastasize than those greater than or equal to 45.
