title: [Study of cancer-associated asthenia: foundation of the ASTHENOS group].
abstract: Asthenia in cancer patients is a highly controversial subject. A distinct definition of asthenia in medical literature is lacking as well as its prevalence and incidence. Also, no simple tools for its diagnosis are available. Moreover its etiopathogenesis is complex and multifactorial, thereby making therapeutic approaches difficult. Recently, a Spanish group has been set up for the study and treatment of asthenia in cancer patients. This paper reports on its establishment, objectives and first conclusions.
