Cancer patients with pain due to bone metastases are often treated with external irradiation in order to reduce pain. However, patients may experience a temporary increase of pain shortly after irradiation, a so-called pain flare. This study investigates whether a short course of a drug called dexamethasone may prevent the occurrence of a pain flare. Patients, who are irradiated for painful bone metastases are randomized into three groups. Group 1 receives placebo during four days, group 2 receives dexamethasone on the day of the irradiation and placebo during three days, and group 3 receives dexamethasone during four days. All patients complete a questionnaire on pain, side-effects of treatment and quality of life during 14 days and after four weeks. This study will define whether dexamethasone decreases the occurrence of a pain flare after irradiation for painful bone metastases, and, if so, whether four days of treatment with dexamethasone is better dan one day of treatment.

Primary Outcome Measures:
  • The occurrence of a pain flare. [ Time Frame: Within 2 weeks after irradiation ]
    A pain flare is defined by a two-point increase after radiotherapy of the worst pain score on Pain flare is defined as an 11-point scale of 0 (no pain) to 10 (worst imaginable pain) compared to baseline without a decrease in analgesic intake, or a 25% increase in analgesic intake without decrease in worst pain score (according to international bone metastases consensus guidelines) (Chow 2007).

Secondary Outcome Measures:
  • Pain scores [ Time Frame: Days 1-14 and 28 ]
    Pain scores as measured by BPI

  • Quality of life [ Time Frame: Days 7, 14 and 28 ]
    As measured by the quality of life scale of the EORTC PAL15

  • Side effects [ Time Frame: Day 1-14 ]
    As measured by questionnaire
