OBJECTIVE: We sought to assess the reliability of repeated sonography in the detection of cervical lymph node metastases at the earliest stage during a follow-up period in patients with stage I or stage II carcinoma of the tongue. STUDY DESIGN: Eighteen consecutive patients with stage I or II squamous cell carcinoma of the tongue were included. When possible, every patient was examined with sonography approximately every 2 weeks during the follow-up period. RESULTS: With repeated sonography on 18 patients, 7 metastatic nodes of 7 patients (39%) meeting our criteria were found. With the use of computed tomography, we diagnosed 10 nodes (including the 7 nodes observed with sonography) in these 7 patients as metastatic. A histopathologic examination revealed that 12 nodes in the same 7 patients had metastatic foci. For sonography, the sensitivity per node was 58%, whereas that of computed tomography was 83%. CONCLUSIONS: Follow-up sonography enabled the detection of all patients who had subsequent subclinical lymph node metastases. However, the sensitivity of sonography in the detection of smaller metastatic nodes was lower than that of computed tomography.
