UNASSIGNED: The present study aimed to investigate the clinical features of nasal mucosa malignant @entity320 , including the histopathological features and factors affecting prognosis. A retrospective analysis of the clinical data obtained from the Department of Otolaryngology Head and Neck Surgery, Tianjin Huanhu Hospital (Tianjin, China) between October 1999 and June 2013 was performed using the Kaplan-Meier method. In total, 29 cases of nasal mucosal malignant @entity320 were analyzed. The overall 3- and 5-year survival rates were 48.3 and 27.6%, respectively. The study group consisted of 18 males and 11 females, with a median age of 61.5 years. Overall, 19 @entity1 underwent surgery, 28 received radiotherapy and 17 received chemotherapy. The American Joint Committee on @entity5 staging system (AJCC) was used to retrospectively stage the @entity5 . In total, 8 were @entity5 stage (T)1, 10 were T2, 6 were T3 and 5 were T4. The results revealed that the T stage, surgical treatment, location of the @entity5 and the presence of black pigmentation affected the 5-year survival rate of the @entity1 . By contrast, radiotherapy and chemotherapy had no effect on the overall survival rate. Overall, endoscopic or endoscopic-assisted surgery were the preferred methods of treatment, and histological features, including the presence of @entity5 melanin pigmentation, affected the prognosis of the @entity1 . This study indicated that the AJCC staging system is able to effectively predict the prognosis of @entity1 with nasal mucosa malignant @entity320 .
