Carcinoid (neuroendocrine carcinoma) of the larynx

Carcinoid of the larynx is a rare aggressive malignancy with few long-term survivors. Three cases of laryngeal carcinoid treated at the University of Michigan and 23 cases reported previously are reviewed. The clinical behavior, patterns of metastasis, and response to therapy were analyzed to determine optimal therapeutic evaluation and treatment strategies. Patient survival did not correlate with clinically evident regional adenopathy, length of symptoms, extent of laryngeal surgery, or retrospective staging according to American Joint Committee guidelines on cancer of the larynx (AJC-1980). Distant metastatic spread occurred frequently and was the most common cause of death. Surgical therapy is currently the only effective treatment for primary or recurrent disease. Future treatment regimens must address distant spread of tumor.
