Metastatic bone pain is acommonly encountered clinical condition seen in oncology clinical practice. About 50% of all cancer patients develop metastases in their lifetime and half of them develop skeletal metastases. Despite its importance, no specific therapeutic strategy, to prevent or treat this complication of cancer has been demonstrated. This study comparing two radiotherapy regimens was conducted at a cancer center in New Delhi, India. Patients with confirmed bone metastases were randomized into two treatment arms, Group A (single fraction) and Group B (multiple fractions). Patients were followed up for 12 weeks. Pain relief was the primary endpoint of the treatment. Other parameters were improvement in analgesic score, performance status, and acute side effects like nausea, vomiting, tiredness, and lassitude. Fifty patients were evaluated at the end of the study. Overall response rate was seen in 86% of cases, whereas complete response was seen in 36% of cases. The two treatment regimens were found to be comparable with respect to other endpoints. Hence, a single fraction treatment, which is more convenient and cost effective, is a more logical approach in the Indian scenario in selected cases.
