A study of 60 patients with colorectal adenomatous polyps showed that serum CRP concentrations were higher in patients with adenomas located proximally (8.674 ± 9.19 μg/ml) compared with the control group (4.94 ± 5.53 microg/ml; P < 0.05) and that CRP levels may be associated with the development of tumors in the proximal part of the colon. Here, CRP is linked to adenoma.
