Immunonutrition Associated with the Protein Module in the Nutritional Evolution of Lung Cancer Patients Undergoing Systemic Treatment: Case Report

Abstract

Background: Lung cancer patients are at high risk of malnutrition. Methods: Case report of two elderly patients diagnosed with lung cancer were followed up during chemotherapy and/or immunotherapy. Patients used nutritional supplementation combined with immunonutrition and Whey Protein module alone during 4 treatment cycles. For nutritional and functional assessment, the following were used: Body Mass Index, percentage of weight loss, calf circumference, Patient Generated Subjective Global Assessment, muscle strength by dynamometer, SARC-F, Barthel Index, biochemical tests and food recall of 24 hours. Results: During follow-up, patients were able to maintain adequate nutritional status, as well as functionality, and were not at risk for sarcopenia. Muscle strength varied, but not significantly. Conclusion: Immunonutrition associated with the protein module appears to be beneficial in cancer patients during systemic treatment.
