Objective: To evaluate the association between blood of C-reactive protein concentrations and
an indicator of muscle mass in hospitalized cancer patients. Methods: A cross-sectional study
carried out with 110 patients of both sexes, aged ≥18 years, with solid and/or liquid cancer
undergoing clinical and/or surgical treatment. Clinical and socioeconomic data were obtained
from medical records. The adductor pollicis muscle thickness was obtained using skinfold caliper.
Patients were divided into two groups: altered adductor pollicis muscle thickness (<13.4 mm)
and normal adductor pollicis muscle thickness (≥13.4 mm). Logistic regression was performed to
verify the association between adductor pollicis muscle thickness and C-reactive protein. Results:
It was observed that 90% (n = 100) of the patients were classified with reduced adductor pollicis
muscle thickness, higher prevalence of the solid tumor, low usual weight, current weight, and
body mass index. The logistic regression analysis showed no association between the adductor
pollicis muscle thickness and C-reactive protein concentrations, in any of models used: model
without adjustment (OR: 1.01; 95% CI [0.94-1.09], p = 0.65); adjusted for sex and age (OR: 1.01;
95% CI [0.94-1.09], p = 0.61); and adjusted model for sex, age and body mass index (BMI) (OR:
1.04; 95% CI [0.96-1.13], p = 0.29). Conclusion: Although adductor pollicis muscle thickness is
validated method for nutritional assessment, we did not find an association with the inflammation
marker (C-reactive protein).
