The In Situ Expression of IL-6 and IL-1β in breast cancer patients

Abstract

Breast cancer is the second most common cancer in women world. Multiple Cytokines appear to have a dominant role in human breast cancer formation. Estimation of the in situ expression of IL-6 and IL-1&#946; in breast cancer patients. A sixty patients with breast cancer BC were divided into two clinical subgroups, (30) with malignant breast cancer MBC and (30) with benign breast tumor as a control group according to histological examination. In situ hybridization technique used for detection of IL-6 and IL-1&#946; mRNA sequence in two groups. The results showed that percentages of mRNA expression of IL-6 and IL-1&#946; were in (&#8805; 11-50%) for malignant breast cancer. This research also investigated that (73.3%) of benign breast tumor were expression less than (<10%) for IL-6 and IL-1 &#946; mRNA. The ISH expression of the mean percentages of IL-6 and IL-1 &#946; were higher levels in malignant breast cancer patients ( 48.13 and 56.07 ,respectively) than benign tumor (2.73 and 1.40 ,respectively), with highly significantly differences (P<0.01) of ISH expression for IL-6 and IL-1 &#946; mRNA among two studied groups., the expression of IL-6 and IL-1 &#946; mRNA are significantly elevated in the tissue of breast cancer patients compared with benign tumor and was found a significant correlation between the expression of IL- 6 and IL-1&#946; mRNA in the tissue of breast cancer patients, thus the results of the present study might be explain the pathological role of these two cytokine in breast cancer.
