Prospective Evaluation of Frailty in Patients With Head and Neck Tumors Before Curative Intended Therapy

"Frailty is assessed using the G8 questionnaire.~Secondary objectives include the assessment of quality of life and financial burden (EORTC-QLQ C30+ H\&N43), swallowing function, cardiopulmonary resilience (6-minute walk test) and the patient's wishes regarding a prehabilitation program. Epidemiological and disease-related data is also collected."
