Small cell undifferentiated carcinoma of the larynx: Report of two patients and review of 13 additional cases
- 1 January 1983
Abstract
Two patients with small cell undifferentiated carcinoma of the larynx (SCUCL) are described and 13 additional well-documented cases are reviewed. SCUCL affects middle-aged and elderly smokers and has a 2:1 male predominance. Half the patients presented with cervical metastases, an additional 43% developed regional metastases, and 71% ultimately had distant metastases. Thyroid gland involvement occurred in 29% of cases. Ten of fourteen patients had died of their neoplasms (mean survival, 7.8 months). One was living with unresectable tumor. Three were clinically disease-free, 30, 15, and six months, respectively, after diagnosis. Following initial therapy, six patients had recurrent or persistent local tumor or regional metastases. None of them received both total laryngectomy and ipsilateral cervical lymphadenectomy. Four of the six patients had radiation, suggesting that radiotherapy was not always effective in the control of local or regional disease when used in lieu of more extensive surgery. Three patients received chemotherapy, in addition to other modes of treatment, and their mean survival compared favorably with the overall group. The tumor from one of the patients contained a squamous component, and, ultrastructurally, both neoplasms had squamous and neuroendocrine features.Keywords
