* All patients were staged as M0. Preoperative staging was based on clinical palpation and conventional anatomic imaging with CT and/or MR imaging, not high resolution MR imaging.
† Primary site previously excised (hence, the “Tx” designation), but no radiation or other therapy to the neck previously received. Patient evaluated and treated for neck disease.
‡ Three patients preoperatively staged as N0 were upstaged to N1 based on pathologic findings.
