Objectives:
The aim of this study was to assess the association between the extracellular water/total body weight ratio (ECW/TBW) and SARC-F scores among elderly gastrointestinal cancer patients.
Measurements:
A cross-sectional study was performed with 57 older male patients with gastrointestinal cancer. Muscle function was assessed using the SARC-F questionnaire. Total body water (TBW) and extracellular water (ECW) were determined using bioelectrical impedance analysis, and fluid retention was assessed as the ratio of ECW to TBW (ECW/TBW). Pearson´s correlation analysis was used to assess the relationship between the SARC-F score and ECW/TBW, TBW and water intake. Results were considered significant at p < 0.05.
Results:
Of the 57 older patients evaluated (65 ± 7 y), 13 ± 8% presented severe weight loss in the last 6 months. The median SARC-F score was 1.0 (0-10), and only four patients had SARC-F ≥4, which indicates the risk of sarcopenia. There was a positive correlation between the SARC-F score and ECW/TBW (r = 0.26, p = 0.02). However, no correlation was found between daily water intake or TBW and the SARC-F score.
Conclusion:
In older gastrointestinal cancer outpatients, we found a positive, albeit low, correlation between the SARC-F score and the ECW/TBW ratio. This outcome indicates the likelihood of muscle function loss due to accumulation of extracellular fluid.
