Body composition and inflammation impact in non-small-cell lung cancer patients treated by first-line immunotherapy.

Lay abstract Inflammation and malnutrition in cancer patients may affect the immune system and response to therapy. We noticed an increase in inflammation and visceral fat and a decrease in muscle and subcutaneous fat during therapy. No variation showed a significant correlation with survival. Muscle mass, adipose tissue and body mass index do not confirm any prognostic impact or relationship with response to therapy. More interesting results were observed with parameters related to inflammation. Probably, for the best treatment choice, a combination of clinical and biological factors will be necessary. Further studies with a multidimensional approach are needed to propose the best treatment and the best support to everyone.
