Elective neck dissection versus observation in the treatment of early oral tongue carcinoma

Abstract

Regional recurrence was the most common cause of failure after surgical treatment of oral tongue carcinoma. Elective neck dissection significantly reduced mortality due to regional recurrence and also increased the overall survival. There was no significant difference between elective radical neck dissection and selective I, II, and III neck dissection in the improvement of treatment results. This retrospective study suggests that elective selective I, II, III neck dissection is a treatment strategy of choice for stages I and II carcinoma of the oral tongue. A prospective randomized study is worthwhile to further evaluate the benefit of elective neck dissection in the treatment of early carcinoma of the tongue.
