Delphian Lymph Node in Laryngeal Carcinoma: A Whole Organ Study

Abstract

The incidence of Delphian or cricothyroid lymph node involvement in laryngeal carcinoma was studied in whole organ sections of 92 laryngectomy specimens. Histologic examination revealed that of the 92 whole organ sections, 8 were noted to have cricothyroid node involvement (8.7%). All 8 patients had submucosal involvement of the conus elasticus, 7 had involvement of the subglottic mucosa, and 6 had invasion of the cricoid cartilage. Four of the 8 patients with cricothyroid node involvement died of the disease, 3 of whom had stomal recurrence. None of the patients who died of disease had surgical management of the paratracheal lymph nodes or postoperative radiation therapy. The benefit of surgical margins of the paratracheal lymph node bed as well as the role of radiation therapy are discussed.
