摘要
A series of 26,826 patients with head and neck tumer as confirmed by pathology from January 1970 to December 1989 are analyzed. It accounted for 39. 5% of all the tumors blopsied in the same interval. In this series, 72. 4% was malignant which accounted for 45. 77% of malignant tumors in different parts of the whole body. For benign tumors in the head and neck, the ratio of male to female was 0. 84:1, and for malignant tumors In the head and neck it was 2. 4:1. The most frequently involved site by the malignant tumors were :nasopharynx, mouth, maxillofacial regions, and neck. THe majority (62. 65%) of malignant tumors were located in the nasopharynx which accounted for 28. 68% of all malignanties of which the ratio of mate and female was 3:1, peak age was 41-50 years, 18 of themwas under 10 years of age, the youngest was 1 1/2 years andthe oldest was 84 years old. These data showed that malignant tunors in the head and neck regions, expecially those in the nasopharynx, are common in Guanxi province, China. The program for cancer research on prevention and treatment should be enforced.
