METHOD: A retrospective study was carried out on 6 cases of NEC. 2 were female and 4 were male. Routine preoperative CT and MRI examination were performed. In one case,the tumor had invaded the brain and then was treated in department of oncology. Five cases were undertaken tumor resection under nasal endoscope, and combined with postoperative chemoradiation therapy. RESULT: The postoperative pathological report of 1 cases was large cell type, the remaining 4 cases were small cell type. One case treated in department of oncology had lived for 2 month with tumor in his body. One cases relapsed and died at 4 month after postoperation, 1 case was lost and 3 case did not relapse till now.
