RESUMO
BACKGROUND: Oncohematological diseases such as lymphoma or leukaemia affect an increasing number of newly diagnosed patients in Spain and other countries. Both disease and treatment may have a negatively impact in the nutritional status of the patient. Malnutrition is not uncommon among oncohematological patients. This situation can compromised the course of the disease, the clinical response of the treatment and the patient's quality of life. METHOD: The implementation of a multidisciplinary approach and a systematic and protocolled nutritional assessment would be useful when dealing with haematological malignancies. RESULTS: We present a proposal of protocol for nutritional intervention in oncohematological patients. This proposal is been developed from the analysis of the published literature as well as clinical practice of a multi-disciplinary team specialized in the management of patients with haematological malignancies.
