目的 :通过对 149例肿瘤患者作恶性肿瘤特异性生长因子 (TSGF)的检测 ,探讨TSGF与恶性肿瘤的关系 ,为肿瘤临床诊断和治疗提供依据。方法 :采用血清比色法。结果 :15 1例正常人TSGF检测结果 :14例呈阳性 ;149例恶性肿瘤患者中 12 7例TSGF为阳性 ,其检测的特导性为 90 .73% ,灵敏度为 85 .2 3%。结论 :TSGF作为一种新的广谱肿瘤标志物对癌症的群体筛查和早期诊断具有一定应用价值。 Objective : To investigate the relationship between TSGF and malignant tumors in 149 cases of tumor patients for the detection of malignant tumor specific growth factor (TSGF), to provide the basis for clinical diagnosis and treatment of tumors. Methods : Serum colorimetry was used. Results : One hundred and forty normal subjects had TSGF test result : 14 cases were positive ; among 149 cases of malignant tumors , 127 cases of TSGF were positive , the specificity of the test was 90 .73% and the sensitivity was 85.22.3 % . Conclusion: As a new broad-spectrum tumor marker, TSGF has a certain value in the screening and early diagnosis of cancer.
