据文献报道甲状腺未分化癌被认为致死性疾病,无论用何种方法,甚少长期生存,预后甚差。Hill 等认为从确诊到死亡时数以月计,Foote 等报道平均4.8月～1年。由于本病发病率低,缺乏大量叠积文献资料报道。大多学者认为一旦确诊为甲状腺未分化癌不必作进一步手术,而采用姑息性放疗、化疗等以期延长生命奏姑息之效。我院外科从1963年～1979年底共收住院治疗甲状腺癌458例,其中25例(占5.4%)为未分化癌。今就其临床特点与治疗方式、疗效方式、疗效等进行分析,并对治疗提出我们的 It has been reported in the literature that anaplastic thyroid cancer is considered as a fatal disease. No matter what method is used, the long-term survival is very rare and the prognosis is very poor. Hill et al. believe that the number of months from the date of diagnosis to death, Foote et al reported an average of 4.8 months to 1 year. Due to the low incidence of this disease, there is a lack of large-scale literature reports. Most scholars believe that once diagnosed with anaplastic thyroid cancer, it is not necessary to perform further surgery, but palliative radiotherapy, chemotherapy, etc. are used in order to prolong the life palliative effect. In our hospital, 458 cases of thyroid cancer were hospitalized from 1963 to the end of 1979, of which 25 cases (5.4%) were undifferentiated cancers. We will analyze the clinical features, treatment methods, curative effects, and therapeutic effects, and present our
