Background & aims: The high prevalence of malnutrition in non-small cell lung cancer (NSCLC) patients has numerous negative consequences on patients’ outcome when undergoing anti-neoplastic treatment. The Global Leadership Initiative on Malnutrition (GLIM) criteria for diagnosis of malnutrition are currently being verified; however, studies validating GLIM criteria in NSCLC patients are lacking. This study aimed to evaluate clinical outcomes and Quality of Life (QoL) in malnourished compared to well-nourished NSCLC patients to determine the predictive validity of GLIM criteria. Methods: We collected data on adverse events, survival, and QoL from NSCLC patients undergoing first line anti-neoplastic treatment collected from two prospective trials. Patients were categorized by GLIM criteria as malnourished or well-nourished, based on non-volitional weight loss, low Body Mass Index, reduced muscle mass (Computed Tomography-scans), reduced food intake (24-h recall), and inflammatory condition (modified Glasgow Prognostic Score). Differences in descriptive data, adverse events, survival, and QoL between the malnourished and well-nourished patients were analyzed. Results: Overall, 120 patients were included in the study. Malnourished patients compared to well-nourished patients had significantly worse outcome in terms of treatment cessation (n = 21 vs 13, p = 0.049), disease progression (n = 20 vs 12, p = 0.034) and shorter overall survival (HR 2.0, 95% CI: 1.2, 3.4, p = 0.009). Stratifying by severity, moderately malnourished patients had a shorter overall survival compared to well-nourished patients (HR 2.1, 95% CI: 1.2, 3.6, p = 0.007). Malnutrition at baseline was associated with poor QoL by lower physical (p < 0.001) and role functioning (p = 0.011), more symptoms of fatigue (p = 0.001), nausea and vomiting (p = 0.009), pain (p < 0.001), dyspnea (p = 0.032), appetite loss (p < 0.001), and constipation (p = 0.029). No significant differences were found in hospitalization, dose reductions, or treatment postponement. Conclusions: Malnutrition defined by GLIM criteria in NSCLC patients was associated with more frequent early cessation of anti-neoplastic treatment, shorter overall survival, and poorer QoL compared to well-nourished patients.
