目的:评价联合彩色多普勒超声(彩超)和计算机断层扫描(CT)检查在甲状腺乳头状癌(PTC)颈部微小转移淋巴结诊断中的价值。方法:回顾性分析中山大学肿瘤医院108例颈部淋巴结临床触诊阴性且同时行颈部彩超和CT薄层扫描检查的PTC患者资料,将其按影像学检查结果分为淋巴结阳性组和阴性组,比较两组之间的实际淋巴结转移率,并结合病理及随访结果,比较联合彩超和CT检查与单一检查方法的诊断符合率。结果:阳性组实际转移发生率为54.2%(26/48侧),阴性组隐匿性转移发生率为22.7%(15/66侧),两组间差异有统计学意义,P<0.05。阳性组中彩超诊断符合率为62.5%(25/40侧),CT诊断符合率为68.6%(24/35侧);联合彩超和CT诊断符合率为85.2%(23/27侧),彩超联合CT同时检查的符合率与两者单独检查的符合率之间差异有统计学意义(P<0.05)。结论:联合彩超和CT薄层扫描检查对PTC颈部微小转移淋巴结的诊断优于单一的检查方法。
Objective: To evaluate the value of combined color Doppler ultrasonography (TCD) and computed tomography (CT) in the diagnosis of micrometastases in the neck of papillary thyroid carcinoma (PTC). Methods: A retrospective analysis of 108 cases of cervical lymph node in Sun Yat-sen University Cancer Hospital clinical palpation-negative and simultaneous cervical ultrasonography and CT thin-section scan of PTC patients, according to imaging findings were divided into lymph node positive group and negative group The actual rates of lymph node metastasis were compared between the two groups. The diagnostic coincidence rates of the combined ultrasonography, CT and single examination were compared with the pathological findings and follow-up results. Results: The positive rate of metastasis was 54.2% (26/48) in the positive group and 22.7% (15/66) in the negative group. The difference between the two groups was statistically significant (P <0.05). In the positive group, the coincidence rate of color Doppler ultrasound was 62.5% (25/40), and the coincidence rate of CT diagnosis was 68.6% (24/35). The coincidence rate of color Doppler ultrasound and CT was 85.2% (23/27) The coincidence rate of coincidence rate of CT examination and coincidence rate of two separate examinations was statistically significant (P <0.05). CONCLUSIONS: The combined color Doppler ultrasound and CT thin-section scan are superior to the single examination in the diagnosis of micrometastable lymph nodes in the neck of PTC.
