NCT01754350

Brief Summary

Increased glucose metabolism is characteristic for solid tumors. Thereby, glucose is important for the generation of ATP, supply of anabolic substrates and defense against reactive oxygen species in tumor cells. In preclinical models, restricting glucose availability using a ketogenic diet, calorie-restriction or transient fasting inhibits tumor growth. Therefore, the purpose of the study is to evaluate whether a calorie-restricted, ketogenic diet and transient fasting can enhance the efficacy of reirradiation in patients with recurrent glioblastoma.

ACTIVE COMPARATOR

nutrition according to recommendations of the German society for nutrition during reirradiation

Dietary Supplement: standard nutrition

Interventions

On day 1-3 and day 7-9, restriction of carbohydrates to \< 60 g and of calories to 21-23 kcal/kg per day, on day 4-6 fasting. On day 1-3 and 7-9, restriction of carbohydrates can be supported by the use of drinks provided by "Tavarlin".
