Value of combined detection of CA125 and VEGF-C,β2-MG in early diagnosis of ovarian cancer lymph node metastasis / 国际检验医学杂志

ABSTRACT

Objective To investigate the value of combined detection of serum CA125 ,VEGF‐C andβ2‐MG levels on early diag‐nosis of retroperitoneal lymph node metastasis in the patients with ovarian cancer .Methods Fifty‐one patients with ovarian cancer undergoing retroperitoneal lymph node cleaning operation were included as the experimental group ,including 29 cases of positive retroperitoneal lymph node metastasis .Contemporaneous 32 cases of benign ovarian tumor were selected as the control group .The serum CA125 level was detected by using electricity chemiluminescence (electrocheminescence) ,serum VEGF‐C level by using en‐zyme‐linked immunosorbent assay (ELISA) and serumβ2‐MG level by using the latex enhanced immune turbidimetric method .The serum CA125 ,VEGF‐C andβ2‐MG levels were compared among various groups .Results The serum CA125 ,VEGF‐C andβ2‐MG levels in the experimental group were (1 682 .5 ± 261 .5)μg/mL ,(2 125 .6 ± 96 .7)pg/mL and (2 .52 ± 0 .61)mg/L respectively , which in the control group were (30 .5 ± 6 .3)μg/mL ,(1 738 .0 ± 79 .8)pg/mL and (1 .87 ± 0 .56)mg/L respectively ,the difference between them was statistically significant (P< 0 .01) .The serum CA125、VEGF‐C、β2‐MG levels in 29 cases of retroperitoneal lymph node metastasis were more significantly higher ,which were (1 997 .3 ± 376 .8)μg/mL ,(2 895 .2 ± 126 .8)pg/mL and (4 .95 ± 0 .69)mg/L respectively ,and the difference was statistically significant compared with the control group (P<0 .01) .The sensitivity ,specificity and accuracy rate of the combined detection of serum VEGF‐C ,β2‐MG and CA125 for diagnosing ovarian cancer retroperitoneal lymph node metastasis were 95 .8% ,97 .3% and 98 .5% respectively .Conclusion The combined detection of serum VEFG‐C ,β2‐MG and CA125 has an important clinical value in early diagnosing retroperitoneal lymph node metastasis of o‐varian cancer .
