Abstract

Small cell neuroendocrine carcinoma of the head and neck is a rarely occurring poorly differentiated and high-grade malignant neoplasm characterized by highly active proliferation of neuroendocrine tumor cells. There are no established therapies for this disease. To clarify the clinical course and develop effective treatment(s) for the carcinoma, we reviewed the data of 8 patients of small cell neuroendocrine carcinoma of the head and neck treated by us between 2006 and 2014 at the Department of Otolaryngology, Gifu University School of Medicine and our affiliated hospitals. The patients consisted of 3 men and 5 women, ranging in age from 38 to 84 years old (mean : 60.9 years). The tumor arose from the nasal cavity or the paranasal sinuses in 3 cases, from the parotid grand in 2 cases, from the oropharynx in 2 cases, and from the hypopharynx in 1 case. The tumor that arose from the hypopharynx was a combined small-cell carcinoma with squamous cell carcinomas, and the one that arose from the oropharynx had already metastasized to the brain. Most of the patients were treated by chemotherapy and radiotherapy based on the treatment employed for small cell carcinoma of the lung. Only the patient in whom the tumor arose from a parana...Continue Reading
