Biological markers of weight loss and muscle protein metabolism in early non-small cell lung cancerMehrfar, Parisa. January 2008 (has links)
The loss of muscle mass leading to cachexia is rarely identified in early lung cancer. Fasting blood and muscle biopsy were collected in 59 non-small cell lung cancer (NSCLC) and 16 non-cancer patients, at the beginning of thoracic surgery. Serum C-reactive protein (CRP), and IL-6 were higher in NSCLC. In weight-losing NSCLC, food intake and serum albumin were lower, CRP, and TNF-alpha were higher. Although the expression of genes of the ubiquitin-proteasome system was not different, ubiquitinated-protein levels were lower and negatively correlated with ph-FOX01 in weight-losing patients. This would suggest lower muscle proteolytic rates in the early stages of NSCLC. Ph-FOXO1 also related to the degree of weight loss and stage of NSCLC. These data suggest that in early stages of the disease, weight and muscle loss could be mainly due to reduced food intake, rather than accelerated proteolysis, which reinforces the potential for successful dietary interventions to prevent or delay the onset of cachexia.
