Can we detect or predict the presence of occult nodal metastases in patients with squamous carcinoma of the oral tongue?

Abstract

All patients with stage T2-T4 squamous cancers of the oral tongue should have an elective dissection of the neck. Patients with T1N0 cancer who have a double DNA-aneuploid tumor, depth of muscle invasion > 4 mm, or have a poorly differentiated cancer should definitely undergo elective neck dissection. Ultrasound and computed tomography are of little value in predicting which patients have positive nodes.
