en Quantitation of Vascular Endothelial Growth Factor and Interleukin-6 in Different Stages of Breast Cancer تخصصي Special مقالات اصلی Original Article <p style="text-align: justify;"><strong><em>Background:</em></strong> Determination of the impact of angiogenesis on tumor development and progression is essential. This study aimed to determine the serum levels of Vascular endothelial growth factor (VEGF) and Interleukin 6 (IL-6) in breast carcinoma, and to correlate them with tumor size, lymph node involvement, and cancer stage.</p> <p style="text-align: justify;"><strong><em>Methods:</em></strong> Under aseptic precautions 5 ml of venous blood was collected from 37 breast cancer patients and 20 healthy females after obtaining due consent and ethical committee clearance. Serum levels of VEGF and IL-6 were determined by enzyme-linked immunosorbent assay (ELISA).</p> <p style="text-align: justify;"><strong><em>Results:</em></strong> Serum IL-6 and VEGF levels were both significantly greater in patients than controls (P = 0.001, P = 0.001, respectively). The serum IL-6 and VEGF levels also significantly correlated with TNM staging (P = 0.001, P = 0.001). Serum IL-6 and VEGF positively correlated with each other (r<sup>2</sup> = 0.668, P = 0.01). Serum IL-6 and VEGF levels did not correlate with tumor size (P = 0.45, P = 0.17) or lymph node metastasis (P = 0.95, P = 0.68).</p> <p style="text-align: justify;"><strong><em>Conclusions:</em></strong> Serum IL-6 and VEGF were greater in breast cancer patients than controls. The levels increased with advanced tumor, nodes, metastasis (TNM) staging, thus correlating with the patients&rsquo; prognoses<strong>.</strong> Serum IL-6 and VEGF levels can be used as diagnostic tools and prognostic factors in breast cancer.</p> Breast cancer, ELISA,IL-6, TNM staging system, VEGF 33 39 http://rbmb.net/browse.php?a_code=A-10-1-81&slc_lang=en&sid=1 Kabbathi Raghunathachar Sahana 10031947532846005545 10031947532846005545 No Center of Excellence in Molecular Biology and Regenerative Medicine, Department of Biochemistry, JSS Medical College, Jagadguru Sri Shivarathreeswara University, Mysore, India.
