Differences in Rate of Decline in CT-defined Skeletal Muscle Mass and Physical Performance in Patients With Advanced Non-small Cell Lung Cancer Receiving Chemotherapy and Targeted Therapy/Immunotherapy, Before and After Treatment.

Lung cancer is a common disease leading to 18 % of cancer deaths worldwide. Despite various improvement in treatment, there still remains low 5-year survival rate of 10-20 % in advanced lung cancer patients. Skeletal muscle mass and physical performance have been shown to effect overall survival and prognosis in lung cancer. This research focuses on effects of different treatment of lung cancer such as chemotherapy, targeted therapy and immunotherapy on skeletal muscle mass and physical performance.
