Brief summary

In patients with cancer, resistance training appears to be a safe and effective exercise modality to increase both lean muscle mass and strength, as well as attenuates cancer-related fatigue. It may serve as a feasible intervention in these patients to mitigate cachexia, especially if implemented before the onset of cancer cachexia or in a pre-cachectic state. This study is a multicenter randomized controlled trial that will compare a blood flow restricted resistance training intervention during the pre- (prehabilitation) and post-operative (rehabilitation) phase in patients with pancreatic, biliary tract and liver cancer, versus usual care on skeletal muscle and other health-related outcomes.

Interventions

OTHERPhysical exercise

The intervention group will receive an exercise program consisting of a combination of supervised and home-based exercise with a focus to induce metabolic stress (blood flow restriction exercise) during both a pre- and postoperative period consisting of a total of 6-10 weeks. Protein supplementation will be given to exclude insufficient intake.
