Determination of Serum Angiopioetin-2 levels in Breast cancer patients at Damascus University Hospitals

Breast cancer has increased universally. Angiogenesis is an essential step for cancer growth, progression and metastasis. Recent studies have focused on Angiopoietin-2 as a promising biomarker in prospecting the prognosis of the cancer.

Determine the relation between serum concentrations of Angiopoietin-2 and clinicopathological data in breast cancer patients.

This study is prospective, cohort type. It includes 30 women with breast cancer, who met the study criteria. The serum Ang-2 value was calibrated using ELISA technique. The data was processed using SPSS program.

Ang-2 serum levels were statistically significant associated with ER status (P = 0.036). However, no significant correlation was observed between serum Ang-2 level and the other clinicopathologic parameters tested, including Histological type (P = 0.417), Clinical grade G (P = 0.91), Clinical stage T (P = 0.913), Clinical stage N (P = 0.086), PR status (P = 0.467), and HER-2 status (P = 0.791). Serum levels of Ang-2 for breast cancer patients was significantly higher than healthy control (20411.33± 6283.19 vs 1731.70± 368.35 pg/ml, P< 0.000). our data indicates that serum levels of Ang-2 has no correlation between the tumor grade and stage in breast cancer patients.
