目的 :通过 CT表现特征判断中晚期甲癌的病理类型 ,为临床制定正确的治疗方案提供依据。方法 :对比分析 36例不同病理类型中晚期甲癌的原发灶 CT表现类型、周围结构侵犯、淋巴结转移灶等的 CT表现特点。结果 :(1)原发灶 CT表现属局限型者多为滤泡癌 ;CT表现属混合型者多为混合癌及未分化癌。 (2 )最易侵犯腺外结构者属未分化癌 ,其次是滤泡癌和混合癌 ;外侵比例最少者为乳头状癌。 (3)不同病理类型甲癌淋巴结转移灶亦具有不同 CT表现特点 ;甲癌原发灶及转移淋巴结灶内钙化特点与甲癌的病理类型无明确关系。结论 :不同病理类型甲癌的原发灶 CT分型、周围结构侵犯、淋巴结转移灶等的 CT表现特点均有所不同 ;掌握其 CT特点 ,有助于判断中晚期甲癌的病理类型 ,为临床制定正确的治疗方案提供依据。
Objective : To determine the pathological type of middle to late stage of the carcinoid by CT features to provide the basis for the clinical development of the correct treatment plan. Methods :Comparison of the CT features of the primary lesions, the surrounding structural invasion, and the lymph node metastases in 36 patients with different types of pathological types of middle or advanced stage cancer was compared. Results: (1) Most of the CT findings of primary lesions were follicular carcinomas; CT findings were mixed types, mostly mixed and undifferentiated carcinomas. (2) The most likely to invade the extra-grenular structure is undifferentiated carcinoma, followed by follicular carcinoma and mixed carcinoma; the least invasive rate is papillary carcinoma. (3) Lymph node metastases of different pathological types of A were also characterized by different CT features. There was no clear relationship between the characteristics of calcification in the primary tumor and metastatic lymph node and the pathological type of the tumor. Conclusions: CT features of primary lesions of different pathological types of carcinoma of the nails, peripheral structural invasion, lymph node metastases, etc. are all different; the mastery of their CT features is helpful to determine the pathological type of middle to late stage cancers. Provide the basis for the development of the correct treatment plan.
