Management of the N0 neck in early cancer of the oral tongue.

Elective treatment of the clinically negative neck in the management of early oral tongue cancers remains controversial. A retrospective review of 71 patients with T1, 2 N0M0 squamous cell carcinoma of the oral tongue treated at the Royal Marsden Hospital was carried out. Cervical nodal recurrence at 2 years was 17% in the group of patients who received elective neck treatment as compared to 43% in the group who had observation of the neck and the difference is statistically significant (P = 0.025). The difference in 5-year survival between the group who had elective neck treatment and the group who did not (75% versus 65%) was not statistically significant. Until future research allows us to be more selective on the basis of a reliable panel of histological and/or biological markers for propensity to nodal metastases, elective neck treatment should be considered in the initial management of the patients with early oral tongue cancer.
