Abstract:
Objective To explore the clinical value of serum cathepsin L (CL),matrix metalloproteinase-9 (MMP-9) and heparanase (Hpa) detection in determining the degree of ovarian cancer invasion and metastasis.Methods Enzyme-linked inmunosorbent assay (ELISA) and electrochemiluminescencl immunoassay (ECLIA) were used to detect the serum content of MMP-9,Hpa,CL in 217 cases with untreated ovarian cancer before surgery( in FIGO Ⅰ - Ⅱ stage 83 cases,Ⅲ-Ⅳstage 134 cases),100 cases with benign ovarian tumors and 101 healthy women control.All of the patients from Guangxi Medical University Affiliated Tumor Hospital,from September 2003 to October 2009.The relationship between the clinical pathological factors of ovarian cancer and serum content of MMP-9,Hpa,CL was analyzed.On the basis of clinical pathological diagnosis as “gold standard”,the ROC curves was drawed to evaluate the clinical value of serum CL,MMP-9,Hpa combined detection in determining the degree of ovarian cancer invasion and metastasis before surgery.Results The serum content of CL,MMP-9 and Hpat in patients with ovarian cancer were (21.23 ± 8.17),( 193.95 ± 42.49),(7.68 ± 2.32) μg/L respectively,which was higher than that in patients with benign ovarian tumors [ ( 10.97 ± 3.84),( 143.66 ± 28.47),( 4.86 ± 1.37) μg/L respectively ] and normal control [ (5.59 ± 1.75),( 57.99 ± 1 1.42),( 2.77 ± 0.80) μg/L respectively ],there was difference statistically significant ( t value CL was - 13.242,- 13.498 respectively; MMP-9 was - 14.521 and - 21.290 respectively; Hpa was - 10.896 and - 18.280 respectively,P ＜ 0.001).The serum content of CL [ ( 21.59 ± 8.24) μg/L ] in patients with epithelial ovarian cancer ( EOC) was significantly higher than that [ ( 19.57 ± 7.69) μg/L ] in non-epithelial carcinoma ( F =1 1.209,P =0.048).The serum CL,MMP-9 and Hpa content in FIGO Ⅰ -Ⅱ stage patients was (19.66 ± 7.83),(182.63 ±42.30),(7.21 ±2.05) μg/L,which was lower than that (22.64 ±8.31),(202.81 ±39.74),(8.51 ± 1.92) μg/L in FIGO Ⅲ-Ⅳ stage patients ( F value was 12.452,70.565 and 195.122respectively,P value was 0.030,0.002 and 0.000 respectively).In patients with EOC,the serum CL,MMP-9 and Hpa content in eases with poorly differentiated was ( 23.04 ± 7.67),( 200.12 ± 40.82),(8.22 ± 1.92) μg/L respectively,which was also higher than that in cases with high-moderate differentiated [ ( 18.54 ± 7.30),( 173.43 ± 39.37),(7.20 ± 2.51) iμg/L respectively;F value was 24.545,60.286 and 9.077 respectively; P was 0.004,0.035 and 0.001 respectively ].The serum content of CL and MMP-9(22.96 ± 8.41),(200.44 ±43.82) μg/L respectively in patients with invasion and metastasis in the abdominal cavity was higher than that without invasion and metastasis in the abdominal cavity [ ( 19.07 ±7.36),( 181.04 ± 36.10) μg/L,F value was 12.210,18.084 ; P value was 0.030,0.010 ] ; There was statistically significant relatioship between serum levels of Hpa and patients with distant metastasis ( F =9.430,P =0.042).On base of pathological diagnosis as gold standard,ROC curve showed the sensitivity was 60.9％ (70/115),69.6％ ( 80/115) and 72.2％ ( 83/115) and specificity was 57.4％ ( 26/62),67.2％(20/62) and 68.9％ (19/62),as serum levels of CL,Hpa,MMP-9 preoperative were detected as tumor markers to determine whether there was cancer invasion and metastasis outside the pelvis.Conclusions There is related with CL,MMP-9 and Hpa levels increase and tumor occurrence and progression in ovarian cancer.The serum content of MMP-9,Hpa,CL detection would be certain clinical reference value to determine extent of invasion and metastasis of ovarian cancer before surgery.
