The population of Niigata prefecture is 2,488,364 with 1,209,883 males and 1,278,531 females, and 2,141 male and 859 female patients, totally, 3,000 patients were registered during these 11 years. The larynx was the most common site (27.8%), followed by the oral cavity (14.8 %) and thyroid gland (11.7 %). HNMT tended to occur in the sixth decade, then seventh and fifth decades of life. Patients more than seven decades accounted for more than 30 % of all HNMT patients. Patients with oral cavity, larynx and thyroid gland tumors tended to be diagnosed at an early T stage, whereas maxillary sinus and hypopharyngeal carcinomas were diagnosed at advanced stages. Nasopharyngeal, mesopharyngeal and hypopharyngeal carcinomas metastasized easily to the cervical lymph nodes. Pathologically, 81.9 % of the HNMT, excluding thyroid tumors, were squamous cell carcinomas. Five year survival rates of HNMT patients treated at Niigata University were\uff1a70 % for oral carcinoma, 54 % for maxillary sinus carcinoma, 84 % for nasopharyngeal carcinoma, 28 % for hypopharyngeal carcinoma, 84 % for laryngeal carcinoma, 64 % for high and moderate grade malignant parotid carcinoma.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3":
