IL-6 and CRP are found to be elevated in various inflammatory and malignant diseases and their levels are found to correlate with the extent of the disease. The primary objective of this study was to determine the preoperative serum levels of IL-6 and CRP in breast carcinoma and to correlate them with the staging of the disease and the prognosis. Methods 59 female patients admitted for breast cancer were identified for the study and were subjected to thorough evaluation. Serum levels of IL-6 were assessed via Enzyme-Linked Immuno-Sorbent Assay ELISA and CRP was measured via immunoturbidimetry. Histological findings included tumour size lymph node LN metastasis and tumour staging. Relevant investigations were made to find out the presence of distant metastasis. Statistical analysis of the data was then processed. Results Increases in cancer invasion and staging are generally associated with increases in preoperative serum IL-6 levels. IL-6 and CRP levels correlated with LN metastasis P P and TNM stage P P . Tumour invasion and the presence of distant metastasis is associated with higher IL-6 levels P P . When we established the cutoff value for IL-6 level pg dl by ROC curve we noted a significant difference in overall survival OS P . However CRP evidenced no significance with regard to patient s OS levels. Serum IL-6 levels were correlated positively with CRP levels r2 P Conclusion Serum levels of IL-6 correlates well with the extent of tumor invasion LN metastasis distant metastasis and
