Abstract

OBJECTIVE:

To evaluate the efficacy of ultrasonography for the diagnosis of cervical lymph node metastasis in esophageal carcinoma.

SUMMARY BACKGROUND DATA:

Ultrasound (US) examination is useful for diagnosing lymph node metastasis. However, few reports have examined its role in the decision to perform cervical lymph node dissection in esophageal carcinoma.

METHODS:

Ultrasound examination was performed to evaluate cervical lymph node metastasis in 519 patients with esophageal carcinoma. The patients were divided into 5 groups according to treatment received: group 1, 153 patients who underwent curative resection of primary tumor by right thoracotomy and complete bilateral cervical lymphadenectomy; group 2, 112 patients who underwent curative resection of primary tumor by right thoracotomy but without cervical lymphadenectomy; group 3, 78 patients who underwent esophagectomy by left thoracotomy or blunt dissection with or without removal of cervical lymph nodes; group 4, 76 patients with palliative resection without cervical lymphadenectomy; and group 5, 100 patients without any surgical treatment. US diagnosis was compared with histologic findings or cervical lymph node recurrence.

RESULTS:

Lymph node metastasis was detected in 30.8% of patients (160/519). The sensitivity, specificity, and accuracy of US diagnosis in group 1 were 74.5%, 94.1%, and 87.6%, respectively. Cervical lymph node recurrence was seen in 7 patients (4.6%) in group 1, in 4 patients (3.6%) in group 2, and 3 patients (3.8%) in group 3. Although the incidence of cervical lymph node metastasis as determined by US examination was high in groups 4 and 5, almost none of the patients died of cervical lymph node metastasis.

CONCLUSIONS:

Ultrasound examination plays a useful role in the decision to perform cervical lymph node dissection in patients with esophageal carcinoma, particularly in those with potentially curative dissection.
