[Palliative radiotherapy of bone metastases. Comparison between 2 fractionations]

One hundred and twenty two symptomatic osseous metastases in 74 patients were treated with palliative irradiation, using two dose/time treatment plans. Pain relief was obtained in 92% of valuable cases (complete response in 68% and improvement in 24%). The complete responses were obtained in 4 weeks in 64% of responsive patients. The median duration of response was 166 days. In advanced cancer patients the short course radiotherapy achieved the same quality and duration of pain relief as conventional treatment.
