    The comparative analysis of the quantity of matrix metalloproteinases (MMP) 2,7 and 9 in breast cancer is carried out; the concentration of sex hormones receptors and protein HER-2/neu are determined. Authentically high values MMP-2 and MMP-7 are found in a tumor tissue in contrast to the normal one. The elevated concentration of ММР-2 in a tumor is connected with receptor status (p < 0,05). The highest values of concentration ММР-7 and ММP- 9 are found at RE-, RP- and HER-2/neu + tumors, and also in the tumors with the size more than 4,0 cm.ΠŸΡ€ΠΎΠ²Π΅Π΄Π΅Π½ ΡΡ€Π°Π²Π½ΠΈΡ‚Π΅Π»ΡŒΠ½Ρ‹ΠΉ Π°Π½Π°Π»ΠΈΠ· содСрТания матриксных ΠΌΠ΅Ρ‚Π°Π»Π»ΠΎΠΏΡ€ΠΎΡ‚Π΅ΠΈΠ½Π°Π· (ММП) 2,7 ΠΈ 9 Π² ΠΎΠΏΡƒΡ…ΠΎΠ»Π΅Π²Ρ‹Ρ… тканях ΠΌΠΎΠ»ΠΎΡ‡Π½ΠΎΠΉ ΠΆΠ΅Π»Π΅Π·Ρ‹ ΠΈ гистологичСски Π½Π΅ΠΈΠ·ΠΌΠ΅Π½Π΅Π½Π½ΠΎΠΉ Ρ‚ΠΊΠ°Π½ΠΈ, ΠΎΠΏΡ€Π΅Π΄Π΅Π»Π΅Π½ΠΎ содСрТаниС Ρ€Π΅Ρ†Π΅ΠΏΡ‚ΠΎΡ€ΠΎΠ² ΠΏΠΎΠ»ΠΎΠ²Ρ‹Ρ… Π³ΠΎΡ€ΠΌΠΎΠ½ΠΎΠ², Π±Π΅Π»ΠΊΠ° her-2/neu.

Serum concentrations of MMP-2 and MMP-7 did not correlate with their levels in the tumors, were within the normal range, and virtually did not decrease after removal of the primary tumor. Serum levels of MMP-9 in patients were significantly lower than in the control and increased after surgery in 85% patients. No clear-cut relationship between the studied parameters and clinical morphological prognostic factors of breast cancer was detected. Β© 2011 Springer Science+Business Media, Inc

    Aim: To perform aΒ comparative analysis with simultaneous measurement of vascular endothelial growth factor (VEGF), insulin-like growth factorΒ 1 (IGF1) and matrix metalloproteinaseΒ 7 (MMP7) in serum samples taken from healthy women and ovarian cancer patients; to perform association of these markers with their expression in primary tumors depending on clinical, morphological and biochemical characteristics of the disease and its prognosis. Materials and methods: We assessed 54Β treatment-naΓ―ve patients with ovarian cancer aged fromΒ 23 to 74Β years (mean ± SD, 53.2 ± 1.9), being at various FIGO stages of the disease. The control group consisted of 120Β healthy women of matched age and reproductive status, in whom serum biomarker levels were studied. Patient survival was assessed by the Kaplan-Meier method, with survival curves compared with log-rank test. All analyses were done with β€œSTATISTICA” and SPSS software. Results: Serum VEGF levels in ovarian cancer patients were significantly (p  0.0001) higher compared those in the control. The most informative cut-off values differentiating the groups studied were serum VEGF values of  350Β pg/ml (median value in the control) and  505Β pg/ml (upper quartile in the control). With 505Β pg/ml taken as aΒ threshold, the test had sensitivity of 79.6% and specificity of 75%. Another cut-off value of serum VEGF level between the patients with ovarian cancer and the control group (510Β pg/ml) was derived from ROC curves and 75%Β sensitivity and 78.2%Β specificity. No acceptable cut-off value for serum IGF1 to differentiate between the patients with ovarian cancer and the controls could be obtained from the ROC curves. Serum MMP7 levels in the patients with ovarian cancer were significantly higher than those in the control group (Mann-Whitney test p  0.0001). With ROC curves, the best sensitivity to specificity ratio for MMP7 value of 4.6Β ng/ml was obtained to differentiate between the patients with ovarian cancer and the controls (sensitivity 83.3%, and specificity 81%). The variance analysis did not reveal any association between serum VEGF, IGF1 and MMP7 and age of patients with ovarian cancer, tumor histology, concomitant somatic and gynecological diseases, and CA-125 levels. Serum VEGF and IGF1 levels did not correlate with the stage of ovarian cancer, in contrast to MMP7, whose levels were significantly higher in stages IIIc–IV. The median VEGF level significantly increased as the degree of differentiation decreased from 510 to 622Β pg/ml (p  0.002), while median IGF1, on the contrary, decreased fromΒ 219 to 116Β pg/ml (p  0.0001). There was aΒ direct correlation between serum and tumor VEGF levels in ovarian cancer patients (r = 0.65, p  0.0001). On the contrary, there was an inverse correlation between serum and tumor IGF1 levels (r = -0.68, p  0.0001). Serum and tumor MMP7 levels remained unrelated to each other. Tumor VEGF, IGF1 and MMP7 content was unrelated to the age of the patients, their reproductive status, presence of concomitant somatic and gynecological diseases, histology of ovarian cancer, and serum CA-125Β levels. VEGF levels in the tumor were not associated with the stage of ovarian cancer, but in patients with initial stages Ia and Ib stages MMP7 values significantly lower (2.1Β ng/mg protein) compared to those in stages IIIc and IV (6.1 and 4.7Β ng/mg protein, respectively, p  0.05). Similar pattern was noted for IGF1: tumor IGF1 values in the patients with stagesΒ Ia–Ib were significantly lower (0.5Β ng/mg protein) than those with stages IIIc–IV (median, 1.3–1.4Β ng/mg protein). AΒ significant increase in both serum and tumor VEGF levels was detected in the patients with ovarian cancer with decreased degree of differentiation. On the contrary, tumor IGF1 levels, but not serum ones, were significantly increased from 0.6 to 1.4Β ng/ml in the patients with poorly differentiated ovarian cancer. MMP7 tumor expression did not depend on the degree of its differentiation. Serum VEGF levels above 700Β pg/ml and tumor levels of above 590Β ng/mg protein should be considered as unfavorable prognostic factors in patients with ovarian cancer.Π¦Π΅Π»ΡŒΒ β€“ провСсти ΡΡ€Π°Π²Π½ΠΈΡ‚Π΅Π»ΡŒΠ½Ρ‹ΠΉ Π°Π½Π°Π»ΠΈΠ· ΠΎΠ΄Π½ΠΎΠ²Ρ€Π΅ΠΌΠ΅Π½Π½ΠΎΠ³ΠΎ опрСдСлСния Ρ„Π°ΠΊΡ‚ΠΎΡ€Π° роста эндотСлия сосудов (VEGF), инсулиноподобного Ρ„Π°ΠΊΡ‚ΠΎΡ€Π° роста 1-Π³ΠΎΒ Ρ‚ΠΈΠΏΠ° (ИЀР-1) и матриксной ΠΌΠ΅Ρ‚Π°Π»Π»ΠΎΠΏΡ€ΠΎΡ‚Π΅ΠΈΠ½Π°Π·Ρ‹ 7-Π³ΠΎΒ Ρ‚ΠΈΠΏΠ° (ММП-7) в сывороткС ΠΊΡ€ΠΎΠ²ΠΈ Π·Π΄ΠΎΡ€ΠΎΠ²Ρ‹Ρ… ΠΆΠ΅Π½Ρ‰ΠΈΠ½ ΠΈΒ Π±ΠΎΠ»ΡŒΠ½Ρ‹Ρ… Ρ€Π°ΠΊΠΎΠΌ яичников, ΠΎΠΏΡ€Π΅Π΄Π΅Π»ΠΈΡ‚ΡŒ связь этих ΠΌΠ°Ρ€ΠΊΠ΅Ρ€ΠΎΠ² с их экспрСссиСй Π²Β ΠΏΠ΅Ρ€Π²ΠΈΡ‡Π½Ρ‹Ρ… опухолях с учСтом клиничСских, морфологичСских и биохимичСских характСристик заболСвания ΠΈΒ ΠΏΡ€ΠΎΠ³Π½ΠΎΠ·Π°.
