Small Cell Neuroendocrine Carcinomas Arising in the Head and Neck Region

Chemoradiotherapy was a reasonable treatment for patients with SCNEC-HN. Those with N0/1 or maxillary sinus SCNEC-HN had a better prognosis than those with N2 disease or cancers at other sites, respectively. However, more aggressive treatment might not be warranted even for patients with limited disease. The outcomes continue to be suboptimal, and more effective therapies are needed because most patients had local or distant failure.
