RESUMO
Treatment of anaemia is a very important aspect in the management of cancer patients. In order to carry out a consensus process about the use of erythropoietic stimulating agents (ESAs) in cancer patients, the Spanish Society of Medical Oncology (SEOM) elaborated a working group which coordinated a panel of medical oncology specialists. This working group has reviewed the main issues about the use of ESAs. In addition a consensus meeting was held in Madrid on 25 April 2007. The following conclusions were made: Since ESA treatment increases the haemoglobin (Hb) level and decreases the red blood cell (RBC) transfusion requirements, ESAs should be used within the approved indications in patients undergoing chemotherapy treatment, beginning at a Hb level below 11 g/dl and maintaining it around 12 g/dl, with iron supplements if necessary. Neither increasing the ESA dose in nonresponders nor the use of ESAs in the treatment of chronic cancer-related anaemia is recommended (AU)

INTRODUCTION: Asthenia is the most prevalent symptom in oncological patients but it is underestimated by the majority of healthcare professionals. The aim of the present study is to estimate the prevalence of tumour-related asthenia in the Spanish population, while defining the associated factors. METHODS: An epidemiological, multicentre, cross-sectional study was conducted in oncology services from Spain, including 712 cancer patients (58.4+/-13.5 years). RESULTS: 42.5% patients showed asthenia. This prevalence appeared to be tumour-related (p<0.05) and increased among patients with a more advanced stage of disease or with a worsening of performance status (p<0.001). The prevalence of asthenia increased in the presence of the following factors: chemotherapy (in the past: 52.1% vs. 31.0%; at the time of the study: 46.1% vs. 38.2%), symptomatic treatment (in the past: 60.4% vs. 39.8%; at the time of the study: 61.3% vs. 38.6%), present interferon treatment (100%), anaemia (59.7% vs. 31.3%), dehydration/waterelectrolyte imbalance (58.3% vs. 41.6%), respiratory failure (61.4% vs. 39.7%), liver disease (59.5% vs. 41.3%), malnutrition (76.1% vs. 38.7%), pain (57.7% vs. 27.0%), anxiety (56.1% vs. 38.6%), depression (57.9% vs. 40.0%) and sleep disturbances (51.1% vs. 39.4%). A multivariate logistic regression showed that a model including performance status, patient circumstance, chemotherapy, anaemia, pain and anxiety correctly diagnosed asthenia in 70.9% of cases. CONCLUSIONS: The physiopathology of tumour-related asthenia remains relatively unknown, despite its high prevalence and considerable quality of life impact. Determining factors related to asthenia in clinical practice can favour the use of concrete treatments and improve the conditions of cancer patients.
