Osteosarcoma is a rare malignancy; however, it is still the most common primary bone tumor in adolescents and young adults. Chemotherapy improves survival indubitably in osteosarcoma; nevertheless, the concern is the stagnant progress since the last several decades. There are a handful of active agents and unresolved issues, especially in choosing the ideal chemotherapy regimen. The oncology community is in equipoise regarding the position of high‐dose methotrexate (HDMTX), mandatory or adjunct. The choice of therapy becomes widely relevant, including in low‐ and middle‐income countries (LMIC), where HDMTX administration brings additional complexities. Research into novel non‐HDMTX‐based protocols adapted to the available resources is pivotal in improving disease outcomes, especially in LMIC. The current review focuses on real‐world challenges in decision‐making and provides a comprehensive overview of the evolution of treatment protocols in LMIC.
