ABSTRACT
Objective To investigate the clinical value of serum carbohydrate antigen (CA125,CA199)and vascular endothelial growth factor C (VEGF-C)in early diagnosis of ovarian carcinoma.Methods 51 cases of ovarian cancer patients with retroperitoneal lymph node dissection were performed in the observation group,including 23 cases of ovarian cancer retroperitoneal lymph node metastasis,32 cases of ovarian benign tumor were selected as the control group.The serum levels of CA199 and CA125 were detected by the method of chemiluminescence detection,and the serum VEGF-C level was detected by enzyme-linked immunosorbent assay (ELISA).Results The serum level of CA125 in patients with ovarian cancer (1 682.5 ±261.5)u/mL was significantly higher than that in the control group (30.5 ±6.3)u/mL(P <0.01),serum VEGF-C level in ovarian cancer patients (2 125.6 ±96.7)pg/mL was signif-icantly higher than that in the control group (1 738.0 ±79.8)pg/mL (P <0.01 ).The serum CA199 level of 51 patients with newly diagnosed epithelial ovarian cancer was (72.5 ±30.6)u/mL,serum CA199 level of the control group was (17.4 ±8.5)u/mL,CA199 level of retroperitoneal lymph node metastasis was (134.9 ±72.5)u/mL, ovarian cancer retroperitoneal lymph node metastasis CAl99 serum level were significantly higher than those without lymph node metastasis and the control group (t =7.39,18.34,all P <0.01).The diagnostic sensitivity,specificity and accuracy of serum VEGF-C +CA199 +CA125 in detection of ovarian cancer retroperitoneal lymph node metasta-sis were 95.5%,96.5%,99.5%.Conclusion Combined detection of CA125,VEFG-C and CA199 in serum has important clinical value in predicting lymph node metastasis of ovarian cancer.
