CRP and cancer: However, we did not find significant differences between the BSI-positive and BSI-negative cancer patients in PCT (BSI- n=15, BSI+ n=4, p=0.237) and CRP (p=0.347), which are known biomarkers for infection [1-3], PCT has also been reported to be a biomarker of BSI [4]. ROC analysis found that the AUCs for these biomarkers were ≤0.7 (Table 3).
