9574 Background: Our objective was to evaluate whether the scored PGSGA questionnaire in advanced cancer patients (ACP) might relate better then weight loss (WL) alone to the nutritional, functional, biological and quality of life features of cachexia (C) and to some complications related to this syndrome. Methods: 214 newly diagnosed ACP with non-small cell lung and gastrointestinal primaries were categorized according to PG-SGA triage intervals of 0–1, 2–8 and ≥9 and also according to WL ≤5% or >5%. Baseline assessments included: hand-grip strenght, body composition by DXA, selective measures of symptom and quality of life (QoL), CBC and differential counts, albumin and CRP. Survival hospitalization rates and data on chemotherapy tolerability were recorded during patient follow-up. Beta coefficients (β), odds ratios (OR), and hazard ratios (HR) were estimated to compare patients with >5% WL to those with ≤5% WL and to compare patients with PGSGA of 0–1 to those with 2–8 and ≥9 scores. All analyses were controlled for gender, age, diagnosis (lung/GI), treatment (radio/chemo), survival (at 8 weeks), and medications. Results: PGSGA was better than the simple recording of WL in defining a population of patients that differed for WBC 109/L(>5% WL β: 0.25 vs. 2–8 PGSGA β: 0.57 and ≥9 PGSGA β: 1.72), CRP mg/L (4.12 vs. 2.16 and 17.49), albumin g/L(-0.63 vs -2.60 and -4.45); weakness 0–10 (1.57 vs.1.56 and 3.32), anorexia 0–10 (2.36 vs. 2.36 and 5.17); Brief Fatigue Inventory 0–90 (17.75 vs. 9.89 and 25.15); McGill QoL 10–0 (-0.95 vs. -0.64 and -2.29); grip strength lbs.(-4.04 vs. -8.82 and -8.06); body fat kg. ( -8.74 vs. -5.94 and -11.72). PGSGA was able to better identify patients with higher rates of both hospitalization (2.6 vs. 1.62 and 9.46) and dose reduction of chemotherapy (1.2 vs. 0.58 and 1.74). Finally, PGSGA was able to better characterize patient survival as compared to WL alone (>5% WL HR: 1.85; 2–8 PGSGA HR: 1.6 and ≥9 PGSGA HR 3.35). Conversely, WL alone was associated with higher probability of a sarcopenia diagnosis by DXA (>5% WL OR: 1.56)Conclusions: Our data support the use of the PGSGA versus the simple recording of WL for identifying C, monitoring its clinical course and predicting possible complications of this syndrome in ACP.
