CRP and cancer: CC exhibited hemoglobin concentrations below the reference value of 12 g/dL (11.2 [8.3; 12.1] g/dL) and although serum albumin levels in all groups of the study population were above the reference value of 3.2 g/dL, contents in CC were significantly lower than those of N. Systemic inflammation during cachexia is determined by serum C-reactive protein concentrations above 5 mg/L and we confirmed the inflammatory status of the cachectic cancer patients, since CRP serum levels in CC (11.5 [6.3, 12.7] mg/L) were about 10-fold higher than in the control group (1.15 [0.5; 3.4] mg/L).
