Is There any Role for Serum Cathepsin S, CRP levels on Prognostic Information in Breast Cancer?: The Swedish Mammography Cohort

Is There any Role for Serum Cathepsin S, CRP levels on Prognostic Information in Breast Cancer? : The Swedish Mammography Cohort

Breast cancer is the most common cancer among women, and both low-grade inflammation and cathepsins might have important roles in breast cancer. We questioned whether prediagnostic circulating levels of C-reactive protein (CRP), cathepsin B and cathepsin S were associated with breast cancer risk. Sixty-nine incident breast cancer cases diagnosed after blood collection and 719 controls from the Swedish Mammography Cohort were analysed for systemic CRP, cathepsin B and cathepsin S. Cathepsin S and inflammation (hsCRP) adjusted cathepsin S were inversely associated with breast cancer risk (cathepsin S: OR for top vs. bottom tertile = 0.46; 95% CI = 0.23-0.92; Ptrend = 0.02; hsCRP adjusted cathepsin S: OR of 0.44; 95% CI = 0.22-0.87; Ptrend = 0.02). hsCRP was significantly associated with increased breast cancer risk (OR for top vs. bottom tertile= 2.01; 95% CI = 1.02-3.95; Ptrend = 0.04). No significant association was observed between cathepsin B and breast cancer risk (OR for top vs. bottom tertile= 0.67; 95% CI = 0.32-1.40; Ptrend = 0.30). These observations lead to hypothesis that levels of cathepsin S and hsCRP observed in women who later developed breast cancer may provide prognostic information regarding tumor development and need to be evaluated in prospective studies.
