甲状腺癌合并自身免疫性甲状腺炎的病例并不少见.按Amino等人的混合统计约占甲状腺癌的10%,但大多数学者认为约占10-30%.毫无疑问,免疫系统在机体抗肿瘤中起着重要作用.实验证明免疫淋巴细胞和肿瘤抗原起反应时能产生抑制因素并能消灭肿瘤细胞.但是,至今仍没弄清自身免疫在甲状腺胚细胞癌变的发生发展中究竟起何作用.从1969年至1980年作者所在医院共收治甲状腺癌患者713人,其中199人(28%)伴有自身免疫性病变,弥漫性自身免疫性甲状腺炎40人(占20%),局灶性自身免疫性甲状腺炎42人(占21.1%),局灶性淋巴细胞 Thyroid cancer with autoimmune thyroiditis is not uncommon cases.Amino, etc. by the mixed statistics about 10% of thyroid cancer, but most scholars believe that about 10-30% .There is no doubt that the immune system in the body resistance Tumor plays an important role.Experiments show that immune lymphocytes and tumor antigens react to produce inhibitory factors and can eliminate tumor cells.But, so far still do not understand the role of autoimmunity in the occurrence and development of thyroid blast crisis From 1969 to 1980, the author’s hospital treated 713 patients with thyroid cancer, of whom 199 (28%) had autoimmune lesions, 40 had diffuse autoimmune thyroiditis (20%), focal 42 (21.1%) autoimmune thyroiditis, focal lymphocytes
