[Value of interleukin-8 determination in diagnosis of benign and malignant breast tumor].

The studies were performed in women with breast carcinoma, benign breast tumour and in a control group. Serum levels of IL-8 were determined 1-2 days before surgical procedure, according to the enzyme-linked immunosorbent assay (ELISA). Pretreatment levels of IL-8 were significantly increased in carcinoma patients in relation to the benign tumour and the control group. The frequency of increased results and absolute values of IL-8 levels showed tendency to significant increase with the stage of disease. These results suggested that IL-8 measurement may be useful in estimation of disease progression in women with breast carcinoma.
