Methods FromNovember2009toDecember2010,Thl-typecytokinesinterleukin-2(IL-2),interferon-γ(IFN-γ)andTh2-typecytokines(IL-4,IL-6)expressioninsupernatantsofperipheralbloodmononuclearcells(PBMC)weredetectedbyenzyme-linkedimmunosorbentassay(ELISA)in40breastcancerpatientsbeforeandaftersurgery(Breastcancergroup)and15healthywomen(Controlgroup).
