Contribution of cervical ultrasound and ultrasound fine-needle aspiration biopsy to the staging of thoracic oesophageal carcinoma.
This study was performed to evaluate the use of cervical ultrasonography and ultrasound-guided fine-needle aspiration for pretherapeutic staging of oesophageal cancer. 50 patients with a thoracic-oesophageal cancer (upper third = 8, middle = 36, lower = 6), previously untreated, underwent cervical ultrasonography to detect supraclavicular lymph node metastases (LN). An ultrasound fine-needle aspiration biopsy was attempted in 12 cases of suspected LN. 26 patients were operated on, of which 13 had surgical exploration of the neck. All patients were followed after treatment with special attention to the supraclavicular area. 14 patients (28%) were ultrasonography positive, 5 of 8 in the upper third, 9 of 42 in the two other thirds. Of the 12 patients where a fine-needle biopsy was attempted, 9 showed neoplastic cells (75%). 5 patients had cervical metastatic LN at surgery, and 5 other patients demonstrated supraclavicular LN metastases during the follow-up. There was one false positive and six false negatives from cervical ultrasonography and two false negatives of UGFAB (ultrasound-guided fine-needle aspiration biopsy). The sensitivity and the specificity of the cervical ultrasonography were 68 and 97%, respectively. The pretherapeutic staging was modified: 7 patients initially stage II-III were regraded to stage IV. Cervical ultrasonography is a reliable method of assessment of supraclavicular LN in thoracic oesophageal carcinoma.
