Nowadays more attention is paid to the quality of life during and after cancer treatment, and fatigue is an important factor influencing this. Still little is known about the development of fatigue before, during and after cancer treatment and its contributing factors. We analyzed the level of fatigue, pain, anxiety and activity before and after the treatment of benign or low-grade malignant bone and soft tissue tumours in 43 patients. All patients were treated with surgery only. The mean age of the patients was 40 years (range 20 to 67 years). Fatigue severity was measured with the CIS-fatigue questionnaire, where a score of 35 or higher reflects severe fatigue. The VAS score was used to measure pain (0=no pain, 10=severe pain), and the Dutch version of the Spielberger State-Trait Anxiety Inventory to measure state anxiety. Physical activity was measured with an actometer, worn at the ankle for two weeks. All measurements were done before the tumor surgery and twelve months later.

Severe fatigue was seen in 35% of the patients before they had tumor surgery. After 12 months 32% of the patients still was severely fatigued. The mean VAS pain score was 2,3 before treatment and 2,2 after 12 months. The anxiety score lowered from 38,1 before treatment to 33,2 one year later. Actometer scores increased from 57,7 before treatment to 69,9 after 12 months. Fatigue severity correlated with pain and anxiety both before and 12 months after treatment, but not with actometer scores.

In this study we see that severe fatigue is present in 35% of tumor patients before they are treated, and this percentage remains high (32%) until one year after surgery. Since severe fatigue correlated with more anxiety and pain, these symptoms can help us understand and treat severe fatigue in tumor patients better.
