title: Discontinuous vs in-continuity neck dissection in carcinoma of the oral cavity.
abstract: We compared the results of transoral excision of the primary tumor with discontinuous neck dissection with the results of in-continuity dissection of primary tumor and neck nodes in anteriorly localized squamous cell carcinoma of the oral cavity. We analyzed 27 patients who underwent 28 discontinuous dissections and 34 patients who underwent 40 in-continuity dissections for T2 anterior tongue or floor-of-mouth carcinoma. The overall ipsilateral neck recurrence rate was 11%. The discontinuous dissection group did significantly worse than the in-continuity dissection group, with a neck recurrence rate of 19%. Consequently, the actuarial 5-year survival of patients who underwent a discontinuous dissection was substantially decreased (63%) compared with patients who were treated by an in-continuity dissection (80%). Discontinuous neck dissection, thus, is not to be recommended in oral cancer.
