This study aimed to evaluate the impact of malnutrition and good nutritional status on clinical outcomes and Quality of Life (QoL) in non-small cell lung cancer (NSCLC) patients and determine the predictive validity of GLIM criteria. The results showed that malnourished NSCLC patients had worse outcomes in terms of treatment cessation, disease progression, overall survival, and poorer QoL compared to well-nourished patients.
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 inflam-matory 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.(c) 2022 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.
