[A pathologic analysis on 9,666 cases of tumors of nose, pharynx and throat].
OBJECTIVE
To analyze nasal, pharyngeal and laryngeal tumor patients age, sex and tumors' sites, to find out the relationship of above indices and tumor's pathologic types.


METHODS
9,666 cases of tumors on nose, pharynx and throat diagnosed in West-China Hospital in 1984 to 1999 were analyzed for the constitution of histological type.


RESULTS
1. the ratio of benign and malignant tumor is 1:8.6, it is 1:62.0 in nasalpharynx; 2. papilloma, angiofibroma and angioma are more commonly seen in all 21 kinds of benign tumors; 3. differentiated squamous cell carcinoma, non-keratinized is the most common types in 25 kinds of malignant tumors, the ratio of carcinoma and sarcoma is 11.98 to 1; 4. The average age of patients with malignancy is about 10 years older than that of the patients with benign tumors, and malignant patients are male predominant; 5. squamous cell papilloma of oralpharynx was the most common in all benign tumors; nasopharyngeal carcinoma is the most common in all malignancies, nasal lymphomas are the most common seen sarcoma.


CONCLUSIONS
The histologic types of nasal, pharyngeal and laryngeal tumors are related with patients' age, sex and sites of tumors.
