Abstract
Purpose
Although cancer cachexia is mainly characterized by persistent loss of body weight (BW), usually in response to a malignancy, the pathophysiology of cachexia remains unresolved. To elucidate the relationship between the loss of BW and other related clinical factors, we conducted a nationwide, multi-institutional, prospective, observational study in patients with advanced non-small cell lung cancer (NSCLC).
Methods
Treatment-naïve stage IV NSCLC patients with an Eastern Cooperative Oncology Group performance status (PS) of 0–2 were eligible. BW, handgrip strength (HGS), quality of life (QOL), Karnofsky Performance Scale (KPS), biochemical parameters, and survival were evaluated at baseline and every 4 weeks for 1 year. The relationship between BW loss and other factors was examined by linear regression analysis. Estimated survival curves were drawn by the Kaplan-Meier method and applied by the log-rank test. Clinical factors associated with cancer cachexia were identified through principal component analysis. The generalized estimating equation approach was used to analyze the deterioration of QOL resulting from the progression of cachexia.
Results
A total of 406 patients were analyzed. BW loss was significantly associated with worsening of QOL, HGS, KPS, and biochemical parameters. The incidence of BW loss was observed throughout the study period. Overall survival was significantly shorter in patients as BW loss progressed. BW loss, decrease in HGS, anorexia, and fatigue were identified as core factors of cachexia that contributed to the deterioration of QOL.
Conclusion
BW loss most likely deteriorated QOL and shortened survival in patients with advanced NSCLC and should be closely monitored.
