title: Prognostic significance of lymph node histology in patients with squamous cell carcinoma of the larynx, pharynx, or oral cavity.
abstract: In a double-blind retrospective analysis, sections of lymph nodes regional to head and neck squamous cell carcinomas were microscopically examined to assess morphologically the immunologic pattern of response. Patients whose nodes showed evidence of immunologic stimulation had five-year survival rates significantly higher than those whose nodes showed no evidence of immunologic stimulation. None of the patients whose nodes showed the lymphocyte depletion pattern survived five years. The stage or histologic grade of the tumors did not influence these correlations. Metastases occurred much more frequently in patients whose nodes showed immunologic activity than in those whose did not. The data support the concept that immunologic capacities are important host defense mechanisms against malignancy. Histologic assessment of immunologic activity in regional nodes seems to be an important parameter for predicting survival.
