为制定甲状腺癌术前、术中诊断的严格程序， 减少其误诊误治。选择２７ 项观察指标， 采用Ｓｔａｔａ统计学软件， 对所有指标进行Ｌｏｇｉｓｔｉｃ逐步多元回归分析。单因素分析显示，１９ 项指标在甲状腺良恶疾病的表现中， 有显著性差异 （Ｐ＜ ０． ０５）； 多因素分析表明， ６ 项指标在判断甲状腺良恶性肿瘤作用中， 有显著意义（分析水平： α＝ ０．１）。最后据分析结果建立甲状腺癌的诊断程序。结果表明： ①术中明确诊断是非常重要的阶段。若发现肿块质地硬、与周围组织粘连、肿瘤数目多于一个， 以及肿块是混合性或实质性， 应考虑恶性可能； ②术前仔细体检及综合分析有关辅助检查结果， 将有助于明确诊断。尤其当肿块质地较硬且位于右侧甲状腺时， 须格外注意
In order to formulate rigorous procedures for preoperative and intraoperative diagnosis of thyroid cancer, reduce misdiagnosis and mistreatment. Twenty-seven observations were selected and Stata’s statistical software was used to perform Logistic stepwise multiple regression analysis on all indicators. Univariate analysis showed that 19 indicators were significantly different in thyroid benign and malignant disease (P<0.05). Multivariate analysis showed that 6 indicators were significant in determining the role of thyroid benign and malignant tumors (P<0.05). Analysis level: α = 0.1). Finally, according to the analysis results, a diagnostic program for thyroid cancer was established. The results show that: 1 The diagnosis is a very important stage during the operation. If it is found that the texture of the mass is hard, adhesion to the surrounding tissue, the number of tumors is more than one, and the mass is mixed or substantial, the possibility of malignancy should be considered; 2 careful preoperative physical examination and comprehensive analysis of the results of the auxiliary examination will help confirm the diagnosis . Especially when the mass is hard and located in the right thyroid gland, care must be taken
