Neck level-specific nodal metastases in oropharyngeal cancer: Is there a role for selective neck dissection after definitive radiation therapy?

To determine the extent of the required neck dissection for patients with persistent lymphadenopathy after definitive radiation therapy for oropharyngeal cancer. If feasible, a conservative approach using selective neck dissection would likely minimize the extent of neck fibrosis and other adverse sequelae.Analysis of pretreatment and posttreatment radiologic scans and pathology reports of 76 patients with oropharyngeal carcinoma (35 tonsil; 41...
