RESUMO

OBJECTIVE: The association between cancer-induced weight-loss (CIWL) and poor clinical outcomes in patients treated with immunotherapy is scarcely understood. We evaluated the use of a cachexia-grading system in IO-treated non-small cell lung cancer (NSCLC) patients in order to predict clinical outcomes. MATERIALS: 300 patients with NSCLC, who received immunotherapy during any line of therapy, were included. All patients were graded according to a previously validated cachexia scale, which takes into consideration body mass index (BMI) and weight loss, stratifying patients into five risk categories (0 [pre-cachexia] - 4 [refractory cachexia]). Primary endpoint was overall survival (OS). RESULTS: Ninety-one (30.3%) patients were classified in the low risk category, 176 (58.6%) were classified in the intermediate risk category and 33 (11%) were in the high risk category. Patients classified as low-risk had a significantly longer OS compared with those with intermediate or high risk (22.4 mo, [95%CI: 16.6-NR] vs. 17.1 [95%CI: 13.5-22.4] vs. 8.0 [3.9-18.4]; p < 0.001). In the multivariate analysis, after adjusting for age, hemoglobin and ORR, hazard of death increased as per the cachexia risk scale (Hazard ratio: 1.62 [1.22-2.16]; p = 0.001). CONCLUSION: Cachexia is independently associated with worse OS in NSCLC patients who receive immunotherapy, highlighting the role for nutritional assessment.
