Aims of the Study:Association the cytokines IL-17 and IFN-g in breast cancer patients Infected and non-Infected with toxoplasmosis andtoxoplasmosis only group.
Materialsand Methods: The case control study was conducted on 240 (60) patients with CA. Breast infected toxoplasmosis group, 60 patients with CA. Breast non-infected toxoplasmosis group, 60 patients infected toxoplasmosis without cancer group and 60 healthy controls group) . Both groups patients with CA. Breast were referred to Middle Euphrates cancer center in Najaf and private the clinics for Physicians Oncology , patients infected toxoplasmosis without cancer group were referred to Hospitals in Najaf during the period November2019 to October 2020. Measurement of IgG Toxoplasma and cytokines (IL-17 and IFN-g ) by using Enzyme Linked Immunosorbant Assay.
Results: The showed a levels of IgG Toxoplasma(144 ± 83.4 IU/ml), IL-17 (154.1 ± 55.9 ng/L) and IFN-g(46.6 ± 17.5 ng/ml) in patients of breast cancer infected toxoplasmosis higher than in other studying groups.
Conclusions:A significant elevation levelsIL-17 and IFN-g in breast cancer groups and toxoplasmosis only group in comparison with control and higher a significant elevation levels of IgG, IL-17 and IFN-g in breast cancer infected toxoplasmosis in comparison with breast cancer non-infected toxoplasmosis.
