ObjectiveTo improve the accuracy of preoperative evaluation of cervical lymph node metastasis in thoracic esophageal squamous carcinoma.MethodsForty-two patients with thoracic esophageal squamous carcinoma underwent neck ultrasonography. Enlarged lymph nodes with their long axis greater than 10 mm and a short-to-long axis ratio greater than 0.5 were considered as metastatic.ResultsPreoperative neck ultrasonography revealed the enlarged lymph nodes in 16 patients, but only in 5 (31%) cases the nodes were palpable. Among them 9 were classified as metastatic (cM(1-LN)), including 4 patients with palpable nodes. In 5 cM(1-LN) patients surgical intervention was canceled and the remaining 37 patients underwent trans-thoracic esophagectomy. Cervical node metastasis (pM(1-LN)) was confirmed pathologically in 6 surgical patients, 4 with tumors invading the adventitia (pT3) and the other 2 into the surrounding structure (pT(4)) (pT(1), pT(2) vs. pT(3), pT(4), P = 0.020). All 6 pM(1-LN) patients had concomitant mediastinal node metastasis and 4 of them had upper abdominal node metastasis. Statistically significant relationship was detected between cervical and abdominal nodal status (r = 0.536, P = 0.007). In comparison with the results of pathological examination and treatment response, the accuracy and sensitivity were 81% and 95% (P = 0.043), 36% and 82% (P = 0.081), respectively, for palpation and ultrasonography. Five out of 39 (13%) patients had their therapy changed due to ultrasonographic findings.ConclusionsNeck ultrasonography for cervical lymphadenopathy is of high sensitivity and accuracy, which plays an important role in the preoperative evaluation and therapeutic decision-making.
