Summary
Brief summary (as posted)
The purposes of this study are * to test the hypothesis that elimination or reduction of dietary animal proteins leads to an improved prognosis in tumor patients * to estimate the effect size and thus to enable sample size calculations for further studies * to test the feasibility and tolerance of different diets, especially a vegan diet, in cancer patients and to proof that a vegan diet does not lead to a deterioration of health, tumor progression or to malnutrition * to test the online platform as a study platform * to test validity of self reported and online generated data
