High serum CRP concentrations have been correlated with elevated IL-6 serum concentrations (Pelliniemi et al, 1995; Ljungberg et al, 1997) and with poor prognosis in solid tumours such as colorectal cancer (Chung and Chang, 2003) and with mortality in RCC (Karakiewicz et al, 2007). Here, IL6 is linked to renal cell carcinoma.
