Moreover, circulating cutaneous T-cell attracting chemokine (CTACK) levels were nominally associated with the risk of kidney cancer (OR=0.72, 95% CI: 0.64-0.85, P=1.64×10-4), melanoma (OR=0.87, 95% CI: 0.79-0.95, P=0.002), non-Hodgkin lymphoma (OR=1.29, 95% CI: 1.11-1.49, P=6.90×10-4), pancreatic cancer (OR=1.50, 95% CI: 1.20-1.87, P=4.17×10-4) and prostate cancer (OR=0.85, 95% CI: 0.79-0.92, P=1.58×10-5). The gene discussed is CCL27; the disease is prostate carcinoma.
