Context: Osteogenic Sarcoma (OGS) is the fifth most common malignancy among adolescents aged 15–19. With multimodality therapy, the long-term survival has improved from 16% in the prechemotherapy era to around 70% in the postchemotherapy era. Aim: This study aims to determine the clinical profile and survival of children with OGS being treated with limb-salvage surgery (LSS). Subjects and Methods: This is a retrospective analysis of all cases of OGS (age ≤ 19) who underwent LSS at our center between June 2009 and February 2017. Baseline characteristics were noted and multivariate analysis was performed for various variables to identify predictors of survival. Results: Among 44 cases studied majority were boys (n = 27). Ninety-three percentage (n = 41) were adolescents. Stage 2 disease was 75% and Stage 3 disease was 25%. The estimated 3-year overall survival (OS) was 69% (95% confidence interval [CI] 55–86) and the estimated 3-year event-free survival (EFS) was 55% (95% CI = 41–74). OS was significantly improved in patients with &gt;90% necrosis postneoadjuvant chemotherapy (NACT) when compared with  4 cycles (78% vs. 60%,P= 0.04). EFS was significantly better in patients without lung metastasis at presentation (61% vs. 29%,P= 0.04), Stage 2 disease (59% vs. 38%,P= 0.04) and &gt;90% necrosis in the tumor post-NACT (69% vs. 35%,P= 0.02). Conclusion: Significant response to NACT predicted improved OS and EFS in children with OGS treated with LSS.
