Bone is one of the most common sites for metastases in primary cancers. The different pain relieving strategies are radiotherapy, opioid analgesics, bisphosphonates etc. There are various fractionation schemes for palliative radiotherapy to the bone. The aim of palliative radiotherapy in bone metastases must be maximum pain relief with minimum mortality within shortest period of hospital stay. We have done a retrospective study to compare the time interval for pain relief in 30Gy/10# vs 20Gy/5# of palliative radiotherapy to bone metastases.
