Brief Summary
The influence of radiotherapy on the protein intake and muscle mass of patients has not been extensively investigated to date. It is also unclear whether the localization of the tumor disease and thus the radiation field have different effects. Therefore, with the pilot study presented here, we would like to record the nutritional uptake of patients before and after radiotherapy. The aim is to determine the amount of energy and protein intake as well as the timing of protein intake. Furthermore, the relationship between the timing of protein intake and muscle mass will be investigated.

Outcome Measures
Primary Outcomes (1)
Protein uptake in g/kg body weight
Change in the amount of protein consumed and its distribution over the main meals by means of a dietary questionnaire before, at the end and 3 months after completion of radiotherapy.
baseline, end of radiotherapy and 3 months after Radiotherapy
Secondary Outcomes (8)
Weight in kg
baseline, end of radiotherapy and 3 months after Radiotherapy
Muscle mass in kg
baseline, end of radiotherapy and 3 months after Radiotherapy
Quality of Life (EORTC QLQ C30) in 5-tier likert scale (higher scores = better)
baseline, end of radiotherapy and 3 months after Radiotherapy
Height in m
baseline, end of radiotherapy and 3 months after Radiotherapy
Fatigue in 5-tier likert scale (higher scores = worse)
baseline, end of radiotherapy and 3 months after Radiotherapy
- +3 more secondary outcomes
