Body protein as a prognostic instrument for cancer patients?

Many cancer patients are affected by loss of appetite, weight loss and fatigue in the course of disease. These symptoms reduce the patients' quality of life, increase morbidity, and lessen tolerance to anti-tumor treatment. In some cases the symptoms are partly caused by various treatment modalities. The aim of this study was to investigate if radiotherapy affects the body weight and body protein of patients, and if changes in body protein have any clinical significance.
