title: Prognostic value of the prelaryngeal node in laryngeal and hypopharyngeal carcinoma.
abstract: The role in tumor spread and the prognostic value of metastasis in a prelaryngeal node were investigated in 124 cases of laryngeal and hypopharyngeal carcinoma selected from about 900 total laryngectomies and pharyngolaryngectomies. Metastasis in a prelaryngeal node was noted in 26 cases: 22 without capsular rupture (N+) and 4 with capsular rupture (N+R+). Vascular embolism (E+) was never noted. Patients with a metastatic prelaryngeal node had a tumor of the piriform sinus in 13 cases (50%), a transglottic tumor in 6, glotto-subglottic in 3, glottic in 2 and supraglottic in 2. They also more frequently had involvement of the cervical nodes (81%) and of the thyroid gland. The 5-year survival in these patients is very poor: only 3 patients (11.5%) were alive and free of disease. These data demonstrate the role of prelaryngeal nodes in tumors that affect the hypopharynx and the antero-inferior portion of the larynx and that directly reach this node through the anterior lymphatic peduncle.
