[Cancer fatigue syndrome]

Tumour-related fatigue, which occurs in almost all tumour patients under therapy--very often even years after a successful therapy--has a considerable impact not only on the quality of life, but apparently also on the course and outcome of treatment. There is little known about where cancer fatigue syndrome comes from. Medical research is required particularly for the continuous states of tiredness persisting for years. The questionnaires currently in use permit an accurate evaluation of the existence and the course of tumour-related fatigue. The treatment of the cancer fatigue syndrome includes the correction of underlying metabolic disorders as well as--even more importantly--physical training and psycho-oncological measures in order to better cope with the disease. Many questions, however, are left open, for instance the impact of cancer fatigue syndrome on disability pensions of tumour patients. The German Fatigue Society (DfaG) was therefore founded in March 2002 in order to find out the correlations between these questions and the cancer fatigue syndrome.
