[The effect of haemoglobin levels on prognosis and quality of life of patients with bronchial carcinoma].
As a consequence of tumour and therapy related effects anaemia is a particularly frequent occurrence in patients with lung cancer. The ensuing symptoms such as dyspnoea, fatigue and decreased general health reduce their quality of life and can impede if not altogether prevent an effective cytostatic therapy. A positive outcome after oxygen-dependent anti-tumour therapy, for example radiation therapy or various cytostatic treatments as well, can be reduced or even put at risk when tumour tissue is hypoxic. In order to treat anaemia, recombinant human erythropoietin can be used beside blood transfusions. Erythropoietins are well tolerated and allow for a long-lasting, gradual increase of Hb-levels, which cannot be achieved via transfusions. Furthermore, transfusion risks such as intolerance reactions or disease transmission can also be avoided. The various studies presented here evaluated the impact of anaemia treatment with erythropoietins on the need for transfusions and quality of life of patients with lung cancer over the last few years. They all agreed in their conclusion that both parameters can be improved with erythropoietin therapy. It turned out that the patients' quality of life improved most when Hb levels reached around 12 g/dl . Studies examining the impact of anaemia treatment on a patient's prognosis also showed positive effects in the majority of cases. In order to investigate this issue, our Heidelberg work group has designed a prospective, randomised phase-III study on NSCLC patients, which will be explained in detail further down.
