| Abstract: | Inflammatory pathways have garnered considerable interest in the recent past as an important mediator of the molecular mechanisms leading to carcinogenesis. The present study was conducted to evaluate the correlation of levels of IL-6 with tumor burden and receptor status in patients of locally advanced carcinoma breast. This prospective study was conducted by the collaborative efforts of the departments of Surgery and Biochemistry, Maulana Azad Medical College and associated Lok Nayak Hospital and GB Pant Hospitals, New Delhi. The study population comprised of 30 cases of locally advanced breast carcinoma recruited from the surgical outpatient department. The various parameters that were evaluated include detailed clinico-pathological profile and IL-6 levels. Tissue specimens received after surgeries were examined for the various characteristics indicative of tumor prognosis. Majority of the patients was in the age group of 41–50 years and was postmenopausal. The serum level of IL-6 increased as the disease progressed from T3N1M0 to T4dN2M0 (41.4 ± 31.9 vs. 164.0 ± 31.1 pg/ml respectively). There was significant correlation of IL-6 levels with lymph node involvement, tumor grade, mitotic index and adipose tissue invasion. Emerging molecular markers are being investigated for breast cancer prognosis assessment and prediction of response to chemotherapy including selection of best possible treatment modality. Our study showed that there is progressive increase in IL-6 levels as the stage of disease progresses. |
