Assessment of distant metastases with ultrasound-guided fine-needle aspiration biopsy and cytologic study in carcinoma of the esophagus and gastroesophageal junction.
The use of ultrasound (US)-guided fine-needle aspiration biopsy (FNAB) for the assessment of distant metastases was prospectively studied in 135 consecutive patients with carcinoma of the esophagus and gastroesophageal junction. Patients with accessible lesions on US and computed tomographic (CT) studies of the supraclavicular regions and the abdomen underwent US-guided FNAB. In patients with multiple lesions biopsies were preferentially performed on enlarged supraclavicular nodes. Forty-nine patients underwent US-guided FNABs of 53 lesions. A cytologic diagnosis was established in 46 of 53 (87%) biopsies. Seven of 53 (13%) biopsies were nondiagnostic. Distant metastases were diagnosed by means of cytologic study in 33 of 135 (24%) patients. Supraclavicular metastases were diagnosed in 22 patients and abdominal metastases were diagnosed in 12 patients, including one patient who also had supraclavicular metastases. US-guided FNAB can improve the selection of patients for surgical and nonsurgical treatment by diagnosing distant metastases in an important number of patients.
