The crude rate of @entity259 per 100,000 population was 2.3 @entity1 and 8.5 @entity1 . The age-adjusted incidence rate showed a gradual increase with age, and the peak of the age-adjusted incidence rate was over 80 years old among @entity1 , and from 70 to 80 years old among @entity1 . According to the Japanese @entity259 Registration Committee, from 1977 to 1999, @entity3557 accounted for more than 85% (30,256) of @entity259 among 35,312 @entity1 . @entity259 (1.4%) and @entity2867 (1.6%) were rare. The female to male ratio of @entity259 was 6.1: 1. Registration was made in accordance with the general rules issued by the Japanese Society of Thyroid Surgery.
