一、组织学分类问题病理分型直接涉及到术式选择和远期效果,大体上分为分化癌和未分化癌,前者又分为乳头状癌、滤泡状腺癌、髓样癌三类。乳头状癌以30～40岁女性多见,据高橋从尸体解剖发现其发病率为13.8%,约占甲状腺癌的70%。病理特点是半数癌组织内有微细的钙化小体(即砂粒小体),很少有肺转移,远期效果很好。森本等人报告5年生存率为83～99.4%,10年90.5%,15年94.7～95%,25年86.9%。滤泡状腺癌占甲状腺癌的20%,发病年龄0～50岁。男女之比为1:8～10。局限增殖型预后较好,浸润增殖型预后差。肺、骨转移者 First, the classification of histological problems Pathological classification directly involves the choice of operation and long-term effects, divided into differentiated cancer and undifferentiated cancer, the former is divided into papillary, follicular adenocarcinoma, medullary carcinoma three types . Papillary cancer is more common in women between the ages of 30 and 40. According to Takahashi’s autopsy, the incidence rate was 13.8%, accounting for about 70% of thyroid cancer. The pathological feature is that half of the cancerous tissues have fine calcified bodies (ie, grit bodies) with little lung metastases and have long-term good results. Morimoto et al. reported 5-year survival rates of 83 to 99.4%, 90.5% for 10 years, 94.7 to 95% for 15 years, and 86.9% for 25 years. Follicular adenocarcinoma accounts for 20% of thyroid cancer and the age of onset is 0 to 50 years. The ratio between men and women is 1:8 to 10. The proliferative type has a better prognosis, and the prognosis of invasive proliferation is poor. Lung, bone metastasis
