Combined detection of CA15-3,TSGF,OPN and CA125 in the diagnosis and treatment of breast cancer

Abstract

Objective To explore the clinical value of combined detection of CA15-3, TSGF, OPN and CA125 in the diagnosis and treatment of breast cancer. Methods The serum specimens from 187 patients with breast cancer (cancer group) were collected, tumor markers CA15-3 and CA125 were detected with electrochemiluminescence method, TSGF was detected with chemocolorimetry, and OPN was detected with enzyme-linked immunosorbent assay. Compared with 50 cases of patients with benign breast disease (control group), The relationship between these marker and clinical stage, recurrence and metastasis of breast cancer were analyzed. Results The serum levels of CA15-3, CA125, TSGF and OPN in cancer group were significantly higher than those in control group (P ＜0.05). Four markers in high clinical stage(Ⅲ and Ⅳ stage)[(83.21±28.67), (89.13±32.34), (278.66±137.23) U/ml and (97.4±11.7) ng/ml, respectively] were higher than those in low stage( Ⅰ and Ⅱ stage) [(60.03±19.35), (58.21±17.56), (155.79±113.11) U/ml and (77.5±10.81) ng/ml,respectively] (P ＜0.05), and those in lymphnode metastasis patients and in recurrence patients were significantly higher than those in corresponding groups (P ＜0.05). The sensitivity and specificity of the combined detection of four tumor markers were 96.3 % (180/187) and 80.0 % (40/50), respectively. The average time of combined detection of serum tumor markers was 2 months ahead of the mammographic features in the recurrence patients with breast cancer. Conclusion The dynamic combined detection of CA15-3, TSGF, OPN and CA125 are better markers for monitoring recurrence and metastasis of breast cancer,which are benefit to early diagnosis and interference.
