Bone metastases cavie pain and compromise the quality of life for a large number of
patients with cancer. Autopsy studies have reported that bone metastases were noted in
up to 85% of the patients dying of lung, breast and prostate cancer. Aims of treatment
for bone metastases include pain relief, elimination or reduction of the need for narcotics,
improvement of ambulation, and arrest of local tumor growth that might otherwise lead
to cord compression or pathologic fracture. External beam radiotherapy is well
established as the treatment of choice for localized bone pain due to metastatic disease.
This is sup ported by many retrospective and prospective published data. But studies of
pain control are difficult to analyze because some patients do not survive long enough
to complete a full assessment and there is no objective guideline of assessing severity
of pain. There is still a considerable lack of agreement on optimal radiotherapy,
especially about radiation dose and fractionation scheme Review of the published data
reveals no clear-cut evidence of a dose-response relationship for radiotherapy and bone
pain relief. In practice, both low dose single schedule and aggressive protracted schedule
are used nowadays. In our department, radiation schedule with multiple fractions over a
couple of weeks was traditionally used. To evaluate the efficacy of the palliative
radiotherapy in bone metastatic patients, we retrospectively analyzed the treatment
results in 45 patients who received fractionated radiotherapy in the Department of
Therapeutic Radiology, Chungbuk National University Hospital.
