ABSTRACT
<p><b>OBJECTIVE</b>To improve the accuracy of preoperative evaluation of cervical lymph node metastasis in thoracic esophageal squamous carcinoma.</p><p><b>METHODS</b>Forty-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.</p><p><b>RESULTS</b>Preoperative 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.</p><p><b>CONCLUSIONS</b>Neck ultrasonography for cervical lymphadenopathy is of high sensitivity and accuracy, which plays an important role in the preoperative evaluation and therapeutic decision-making.</p>
