Diagnostic value of TSGF and combined tumor marker determination in patients with malignant tumors / 重庆医科大学学报

ABSTRACT

Objective:To explore the value of tumor specific growth factor (TSGF) and combined tumor markers (AFP,CEA,Ft,TSA) in the diagnosis of malignant tumor.Methods:TSGF was measured by chemical method and combined tumor markers by chemical method and ELISA method.The results in 170 cases with malignant tumors and 60 cases with non-tumor patients were analyzed.Results:In cases of single TSGF measurement,the positive rate was 82% in liver carcinoma,87% in lung cancer,and 86% in carcinoma of stomach,colon,or rectum.The positivity rate of TSGF plus combined tumor marker determination was 97.5%,97.7%,and 97.5% respectively.Conclusion:TSGF plus combined tumor marker determination improve the positivity rate for tumor diagnosis,provide evidence for localization,and promote early diagnosis.
