在美国,甲状腺癌不常见,占全部恶性肿瘤的0.6％。但在儿童和青年,甲状腺癌是同期中相对多见的恶性肿瘤。到1970年为止,Winship已收集文献中报道的青年期甲状腺癌878例。青年期甲状腺癌有其生物学特点,治疗和预后与其他年龄组也不相同。作者将Iowa医院等自1935年以来所治的702例甲状腺恶性肿瘤的资料贮存电子计算机信息系统,随访直至死亡。除去髓样癃和未分化癌(20岁以下者4例,20岁以上者143例),重点对分化良好的腺癌进行分析,共555例,计诊断时年龄为<15岁者29例,
In the United States, thyroid cancer is uncommon, accounting for 0.6% of all malignant tumors. However, in children and youth, thyroid cancer is a relatively common malignant tumor in the same period. By 1970, Winship had collected 878 cases of adolescent thyroid cancer reported in the literature. Adolescent thyroid cancer has its biological characteristics, treatment and prognosis are not the same as other age groups. The authors of the 702 cases of thyroid malignancies that have been treated since 1935, such as the Iowa Hospital, store information on electronic computer information systems and are followed until death. Remove myeloid nevus and undifferentiated carcinoma (4 cases below 20 years old and 143 cases above 20 years old), focusing on the analysis of well-differentiated adenocarcinoma, a total of 555 cases, accounting for 29 cases at diagnosis age <15 years old,
