Prevalence And Correlates Of Critical Malnutrition (Cmn) Among Gastrointestinal (Gi) And Non-Gi Participants In Phase I/Ii (P1/2) Clinical Trials.

770Background: Patients (pts) with cancer, in particular GI malignancies, are vulnerable to CMN from both tumor-related digestive symptoms and treatment-related toxicity (TRT). CMN is associated with poor cancer outcomes, including reduced quality of life, poor treatment tolerance and decreased survival. P1/2 trial participants are not routinely screened for CMN or potentially associated psychological and physical activity impairments. Methods: Baseline assessments of nutrition (PG-SGA), distress (NCCN-DT), anxiety (HADS-A), depression (HADS-D), and sedentary lifestyle (SL, Godin-LTQ) were conducted in pts beginning a P1/2 trial. CMN was defined as a PG-SGA score of ≥9. Statistical significance was determined by Fisher’s exact test. A regression model was used to identify a composite predictor of CMN. Results: 100 pts (87% P1, 13% P2) were enrolled. Results of assessments are shown in Table 1. 39% of pts had CMN and 52% had a SL. CMN was more common in non-whites (p = 0.05) and those on P1 trials (p = 0.0...
