The prognosis of lung cancer is not only related to the stage of disease, but also to the physiological and psychological situation of the patients. Malignant tumors are often associated with weakness and cachexia, leading to less physical activities and worse moods. However, few studies that have attempted to investigate the impact of nutritional status on the prognosis of NSCLC. Existing applications of nutritional scoring systems in early-stage of NSCLC are very limited. Therefore, this study aims to observe the correlation between nutritional status and the prognosis of patients with early-stage NSCLC, to clarify the value in predicting the overall survival rate and progression-free survival rate of NSCLC patients, and to offer evidence for alleviating the social and economic burden of NSCLC.
