Abstract

Prostate cancer (Pca) is the most common form of cancer affecting men, despite recent advances in PCa treatments, one third of patients diagnosed each year succumb to this disease. The inflammatory response has been implicated in prostate cancer progression. The pro-inflammatory transcription factor, NFκB/p65 has been implicated in PCa progression. Few studies have examined the involvement of NFκB and inflammatory signalling in PCa. <p/>Immunohistochemistry was employed to investigate the expression of NFκB/p65, C-reactive protein and Ki67 in 61 clinical samples. <p/>Tumours expressing high levels of p65 (p=0.004), CRP (p=0.011) and Ki67 (p=0.0003) had a shorter disease specific survival. Upon combining p65 and CRP status it was observed that those tumours with low expression of both proteins had a median survival of 11 years compared to 3.9 years for those with tumours with high expression of both (p=0.005). CRP expression was significantly higher in the 21 patients who died of their disease and on multivariate analysis CRP expression retained independent significance (p=0.005). <p/>This study suggests CRP and NFκB may function collectively to drive prostate cancer progression in a subset of patients. Tumoral CRP is a significant independent predictor of cancer specific survival. The relationship between tumour CRP and signalling pathways warrants further investigation in a larger cohort.
