The nuclear factor κB (NF-κB) is a superfamily of transcription factors. It plays an important role in development & progression of cancer. This study was conducted in a tertiary care centre to investigate the significance of NF-κB as a prognostic marker in breast cancer and study its relation with established prognostic markers such as tumor grade, lymph node status, hormone receptor & HER-2/neu expression. We measured NF-κB expression of breast cancer tissue as a test sample & from fibroadenoma as a control. Measurement was done by Western Blot Technique using p65 protein of NF-κB super family of transcription factors. ER,PR and HER-2/neu were measured by immunohistochemistry methods. NF-κB/p65 is significantly associated with large tumor size (≥5 cm), high grade tumors, negative ER, negative PR, positive HER-2/neu and high NPI (≥5.4) scores. NF-κB/p65 expression implies aggressive biological behaviour of breast cancer & this study validates significant association of NF-κB /p65 overexpression with large tumor size, negative estrogen & progesterone receptor status and overexpression of c-erbB2 oncoprotein.
