[Prehabilitation and enhanced recovery after surgery protocols for head and neck cancer : Value and application of these concepts].

Prehabilitation is gaining traction in complex oncological interventions and treatments. This CME article is focused on the basic principles of prehabilitation. We discuss the objective evaluation of physical fitness and how to improve it by physio- and speech therapy. Thereafter, we explain how to judge nutritional status, especially in oncological patients, and discuss modes of nutritional supplementation. Finally, the enhanced recovery after surgery concept is briefly explained and its current value in head and neck cancer patients discussed.
