ABSTRACT

Depending on the size of the tumour, metastasis status and the treatment method applied in lung cancer, the patient's appetite status and the use of nutrients in the body are adversely affected. Thus, the risk of developing conditions like malnutrition and sarcopenia increases. The response to treatment, quality of life and su rvival of the patient whose nutritional status is deteriorated are also adversely affected. In lung cancer patients, it is targeted to strengthen their immune system and antioxidant defence mechanisms and reduce inflammation with immunonutritional support. This review aimed to explain the role of glutamine, arginine, omega-3 fatty acids and RNA nucleotides, which are frequently used as immunonutritional support in medical nutrition treatment in lung cancer.
