Objectives were to document regional resources, maintain a publicly accessible stakeholder map, engage key stakeholders, and strengthen referral pathways. India, the world's most populous country (1.45 billion), has nearly 25% of its population under 15 years. The healthcare system, disparities in resources, access, and cost leave the true childhood cancer burden inadequately defined. Mapping pediatric cancer units (PCUs) is critical to identify the strengths and gaps and help policymakers, non-governmental organizations, funders, and clinicians. The data collection processes developed for mapping India are detailed in this report.</p><p><strong>Procedure: </strong>The Pediatric Hematology Oncology Chapter of the Indian Academy of Pediatrics developed a 98-item survey to assess infrastructure, resources, and support systems.

Treatment escalation decisions remain largely empirical, guided by clinical presentation and conventional laboratory results rather than by an integrated biomarker framework.</p><p><strong>Procedure: </strong>We prospectively enrolled 180 consecutive pediatric patients with HLH at Children's Hospital 1, Ho Chi Minh City, Vietnam (October 2022-October 2025): pHLH, n = 40; EBV-HLH, n = 46 (CD27 intact, n = 19; CD27 dim, n = 27); and sHLH, n = 94. A 15-analyte multiplex cytokine panel and six-marker lymphocyte subset flow cytometry were performed at diagnosis (T0) and Day 7 (T1).
