A total of 82.5% of the total cohort had positive blood cultures present, which were associated with a significantly elevated CRP level (CRP positive BC 4.9 (11.9;1.9) vs. negative BC 2.7 (5.7;0.8) mg/dL; p = 0.001), however, without any differences in AP (AP positive BC 86 (114;70) vs. negative BC 79 (106;64) U/L; p = 0.116). Here, CRP is linked to breast cancer.
