RESUMO
AIMS AND BACKGROUND: The study was undertaken to investigate CCL2/MCP-1, CCL3/ MIP-1α, CCL4/MIP-1ß, CCL5/RANTES and CXCL8/IL-8 women with epithelial ovarian cancer. METHODS AND STUDY DESIGN: Sixteen patients diagnosed with epithelial ovarian cancer and 18 healthy women with no evidence of malign neoplasia (control group) aged from 23 to 89 years (mean ± SEM, 58.7 ± 2.3) were included. The epithelial ovarian cancer patients underwent laparotomy and debulking surgery. Chemokines serum levels were measured by cytometric bead array. Statistical analysis was performed using Mann-Whitney and Kendall's tau. P <0.05 was considered statistically significant for all analyses. RESULTS: The tumor staging (FIGO) was classified into: I in 4 cases (25%), III in 5 cases (31.3%) and stage IV in 7 cases (43.8%). Sera chemokine dosages of CCL2/MCP-1 and CCL4/MIP-1ß were lower in epithelial ovarian cancer patients than in the control group (P = 0.021 and P = 0.030, respectively). No significant difference between groups was observed in the levels of CCL3/MIP-1α, CCL5/RANTES and CXCL8/IL-8. No association between the chemokines analyzed and tumor stage was found. The serum level of CCL4/MIP-1ß was correlated with CA-125. CONCLUSIONS: The study of serum levels of CCL2/MCP-1, CCL3/MIP-1α, CCL4/MIP-1ß, CCL5/RANTES and CXCL8/IL-8 chemokines in epithelial ovarian cancer patients identified a down-regulation in CCL2/MCP-1 and CCL4/MIP-1ß, which suggests that the two chemokines may play an important role in the pathophysiology of ovarian cancer.
