Retrospective observational study of occult cervical lymph-node metastasis in T1N0 tongue cancer

Abstract

Patients with tumors ≥2 mm in thickness or muscle invasion developed neck metastasis, suggesting that elective neck dissection may be warranted for patients with these findings. For preoperative assessment of the need for elective neck dissection, magnetic resonance imaging would be a potential modality for T1N0 tongue cancer.
