Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome parameter in this study is tumour and pancreas specific protein synthesis, expressed as fractional synthetic rate (FSR) [%/day]. This parameter is calculated from: • Plasma and tissue free alanine concentration • Plasma enrichment of alanine • Tissue protein bound enrichment of alanine • Alanine enrichment of the tissue free amino acid pool The FSR can be calculated using the following formula: FSR = ((tissue enrichment biopsy - calculated baseline tissue enrichment)/(saliva enrichment*time of study))*100%. Baseline plasma albumin enrichment will be used to calculate baseline tissue enrichment | — |
Secondary
| Measure | Time frame |
|---|---|
| Tissues/protein-specific FSR will be calculated from: o Albumin o Leukocytes o Vastus lateralis muscle o Rectus abdominis muscle o Liver o Gallbladder o Small intestine o Subcutaneous fat o Visceral fat Plasma protein FSR using an unbiased quadrupole time-of-flight mass spectrometry approach. Regional tumour protein incorporation will be assessed using matrix assisted laser desorption/ionisation mass spectrometry imaging. | — |
