<p>Since its inception in 1987, the Pediatric Hematology Oncology (PHO) chapter of the Indian Academy of Pediatrics (IAP) has emerged as one of its most active and impactful chapters. The chapter has played a pivotal role in improving the care of children with cancer and various hematological disorders in India over the past four decades. It has contributed significantly to the development of the subspecialty in India through capacity-building initiatives, national training programs, guideline development, academic teaching, and conferences. The chapter has also fostered global collaborations and multicentric research, resulting in evidence-based, context-specific improvements in clinical practice. Alongside its sister organization-the research foundation-Indian Pediatric Hematology Oncology Group (INPHOG)—the PHO chapter has elevated pediatric hematology oncology care in India to standards comparable with leading international centers.</p>
