超声联合CT对乳头状甲状腺癌颈部淋巴结转移的术前诊断价值

Preoperative Diagnostic Value of Ultrasound Combined with CT in Cervical Lymph Node Metastasis of Papillary Thyroid Carcinoma

目的分析超声联合CT对乳头状甲状腺癌颈部淋巴结转移的术前诊断价值。方法随机选取我院2017年1月至2018年1月收治的乳头状甲状腺癌患者100例,分别接受超声、CT检查。将诊断结果与病理结果进行对照,分析颈淋巴结转移部位、分期诊断结果、甲状腺癌颈部淋巴结转移诊断结果的阳性值及联合诊断的敏感度、特异度。结果超声、CT、超声+CT乳头状甲状腺癌颈部淋巴结转移部位结果左侧、右侧、双侧阳性率差异比较有统计学意义(P<0.05),阳性率由高到低依次是超声+CT、CT、超声。超声、CT、超声+CT诊断乳头状甲状腺癌TNM分期T1-T2、T3-T4阳性率差异比较有统计学意义(P<0.05),阳性率由高到低依次是超声+CT、CT、超声。超声、CT、超声+CT诊断乳头状甲状腺癌颈部淋巴结转移、未转移阳性率差异比较有统计学意义(P<0.05),阳性率由高到低依次是超声+CT、CT、超声。超声、CT、超声+CT诊断乳头状甲状腺癌颈部淋巴结转移敏感度、特异度差异比较有统计学意义(P<0.05),敏感度、特异度由高到低依次是超声+CT、CT、超声。结论术前超声联合CT诊断乳头状甲状腺癌颈部淋巴结转移价值较好,能明显提高诊断阳性率,减少假阳性,有利于预后。

Objective To investigate the preoperative diagnostic value of ultrasound combined with CT in cervical lymph node metastasis of papillary thyroid carcinoma.Methods 100 patients with papillary thyroid cancer admitted to our hospital from January 2017 to January 2018 were randomly selected and examined by ultrasound and CT.The diagnostic results and pathological results were compared.The location of cervical lymph node metastasis,the results of staging diagnosis,the positive value of cervical lymph node metastasis diagnosis of thyroid cancer,and the sensitivity and specificity of combined diagnosis were analyzed.Results The left,right,and bilateral positive rates of cervical lymph node metastasis of papillary thyroid carcinoma diagnosed by ultrasound,CT,and ultrasound+CT were statistically significant(P<0.05),and were the highest in ultrasound+CT,followed by CT,and ultrasound(P<0.05).The positive rates of T1-T2 and T3-T4 in TNM stage of papillary thyroid cancer diagnosed by ultrasound,CT,ultrasound and CT were significantly different(P<0.05),and were the highest in ultrasound+CT,followed by CT,and ultrasound(P<0.05).The positive rates of cervical lymph node metastasis and non-metastasis in papillary thyroid cancer diagnosed by ultrasound,CT,ultrasound and CT were significantly different(P<0.05),and were the highest in ultrasound+CT,followed by CT,and ultrasound(P<0.05).The sensitivity and specificity of ultrasound,CT,ultrasound and CT in the diagnosis of cervical lymph node metastasis of papillary thyroid cancer were significantly different(P<0.05),and were the highest in ultrasound+CT,followed by CT,and ultrasound(P<0.05).Conclusion Preoperative ultrasound combined with CT in the diagnosis of cervical lymph node metastasis of papillary thyroid cancer has a better value,which can significantly improve the positive rate of diagnosis,reduce false positive,and is conducive to prognosis.
