Context: Pediatric bone sarcoma is a rare entity with low incidence of around 2.5–6 per million population in India. Management of this condition is well standardized, and global survival data are available; however, there is a paucity of data in the Indian perspective. Aim of the Study: The aim of this study is to analyze various prognostic factors and survival outcome. The purpose of this study is to assess the role of surgery, multiagent chemotherapy, and radiation in the management of these tumors. Patients and Methods: Retrospective analysis of patients aged 18 and less, diagnosed as bone sarcomas and treated in our tertiary cancer center. All the patients received at least one form of therapy depending on stage and site of the primary lesion. Results: Twenty-one patients of Ewing sarcoma and 20 patients of osteosarcomas were eligible and were included in the study. In Ewing sarcoma, completing the full course of standard chemotherapy and radiotherapy to the local site was associated with improved survival. In osteosarcoma, limb salvage surgery (LSS) had a significant difference in overall survival compared to amputation. Induction chemotherapy was associated with better percentage of necrosis and showed improved survival. The percentage of necrosis correlated positively with survival which was statistically significant (P = 0.015). Conclusion: The median survival in both these bone sarcomas is inferior to global trends. Probable reasons for such discrepancy are lack of compliance to treatment protocols due to age factors and late presentation. Completion of multiagent chemotherapy in both the tumors add to better survival. Radiotherapy in Ewing sarcoma improves survival. In osteosarcoma, LSS is an oncologically safe alternative to amputation. The percentage of necrosis following chemotherapy in osteosarcoma is a reliable predictor of prognosis.
