Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Lung tumor and healthy lung tissue protein synthesis rates, expressed as fractional synthesis rates (FSR, %/d), will be measured for 5 days prior to tumor resection. | — |
Secondary
| Measure | Time frame |
|---|---|
| The FSRs of NSCLCs will be compared between the different sizes classifications within the cTNM system. Furthermore, the FSRs of NSCLCs will be compared between the different subclassifications (i.e., adenocarcinomas, squamous cell carcinomas, and large cell carcinomas). In addition, correlation analysis will be conducted to determine whether tumor tissue protein synthesis rates are influenced by other patient characteristics (i.e., inflammation, lung function, smoking status, and smoking history). Other characterization measurements include hand grip strength, muscle protein synthesis rates, muscle size (cross-sectional area erector spinae and other muscles at L3), visceral and subcutaneous adipose tissue (VAT/SAT) at L3. | — |
