All the diagnosis were confirmed by pathologic examination. There were 5485 cases (69.62%) of malignant tumors. Nearly an half of malignant tumors were in the nasopharynx (49.32%). Among the malignant tumors of the nasopharynx, 2698 were carcinoma (99.34%) and only 18 (0.66%) sarcoma. Nine of them were under 10 years of age, the youngest patient was 3 years old, and this is rare in our county. The incidence of head and neck tumors was 37.66% and that of the head and neck malignancies was 26.22% of tumors in the whole body. This study indicates that incidence of malignant tumor in head and neck was rather higher, it is worth to improve ths procedure of treatment and prevention.展开更多
