title: Extracapsular spread of carcinoma in cervical lymph nodes. Impact upon survival in patients with carcinoma of the supraglottic larynx.
abstract: The treatment results and histologic findings in the cervical lymphatics of 96 patients with squamous cell carcinoma of the supraglottic larynx were studied retrospectively. The clinical assessment of the extent of disease in the cervical lymphatics correlated poorly with histologic findings. Forty-one percent of patients judged to have no evidence of cervical metastases were found to have carcinoma in the cervical lymphatics. Twenty percent of patients judged clinically NO were found to have extracapsular spread of tumor. Patients were subdivided according to the histologic findings in the cervical lymphatics. Three-year no-evidence-of-disease (NED) follow-up was available on all patients. Patients with no tumor in cervical lymphatics had a 71% 3-year NED. By comparison, patients with cervical metastases confined to the lymph node were 79% NED. Patients with histologic evidence of extracapsular spread of tumor were 45% NED (P less than 0.05). The use of histologic findings in predicting prognosis and treatment planning is discussed.
