Overview

Prospective study explores how PG-SGA and phase angle relate to overall survival in cancer patients, suggesting enhanced nutritional risk evaluation.

Key Points

  • The patient-generated subjective global assessment strongly predicts mortality in cancer patients, with severely malnourished individuals facing a 4.68-fold higher risk of death.
  • Nutritional assessments showed a significant link to overall survival; 51.4% of patients died during the follow-up period.
  • Phase angle demonstrated an association with survival in initial analysis, although it lost significance after adjustments for clinical stage.
  • Integrating clinical and bioelectrical parameters may enhance risk stratification efforts in oncology, emphasizing nutritional screening.
