Abstract

Objective: Individuals with cancer are affected by a loss of cell membrane integrity due to electrolyte imbalance between the intra- and extracellular fluids. Cell membrane integrity and hydration status can be assessed according to the phase angle (PhA) and the risk for sarcopenia, by using the Strength, Assistance for walking, Rise from a chair, Climb stairs, and Falls (SARC-F) questionnaire. To our knowledge, this approach has not been validated in patients with cancer. The aims of this study were to verify the prevalence of the risk for sarcopenia, and to analyze the association between PhA and the risk for sarcopenia with and without adjustment for extracellular water content.

Methods: This was a cross-sectional study conducted with 124 male and female cancer patients (77.4% men). PhA and hydration status were assessed using bioelectrical impedance analysis (BIA), and the risk for sarcopenia (cutoff ≥4) was assessed using the SARC-F questionnaire.

Results: Of the 124 patients, 28 (22.5%) were at risk for sarcopenia (SARC-F ≥4). There was no association between PhA and the risk for sarcopenia in the crude model, nor in the model adjusted for age, sex, smoking, alcohol consumption, and physical activity, nor after adjusting for use of supplements, body mass index, treatment type, performance status, and type and stage of cancer. However, we found an association between lower PhA values and a higher risk for sarcopenia after adjusting for hydration abnormalities (odds ratio, 1.74; 95% confidence interval, 1.03-2.93; P < 0.035).

Conclusion: We found that 22.5% of patients with cancer presented with a risk for sarcopenia. Additionally, an association between lower PhA values and enhanced risk for sarcopenia highlighted the importance of adequate hydration and evaluation of fluid status via BIA as a new recommendation to prevent sarcopenia.
