Based on publication date, here are the **pediatric cancer studies published in the last 5 years (2021–2026)** in cBioPortal:

| Study ID | Cancer Type | Name | Samples | Publication |
|---|---|---|---|---|
| **aml_stjude_2024** | AML | Pediatric Acute Myeloid Leukemia (St. Jude, Nat Genet 2024) | 887 | 2024 |
| **nbl_msk_2023** | Neuroblastoma | Pediatric Neuroblastoma (MSK, Nat Genet 2023) | 223 | 2023 |
| **rms_msk_2023** | Rhabdomyosarcoma | Pediatric Rhabdomyosarcomas (MSK, JCO Precis Oncol 2023) | 24 | 2023 |
| **pancan_pdx_uthsa_2023** | Mixed | Pediatric solid tumor PDXs (UTHSA, Nat Commun 2023) | 136 | 2023 |
| **mixed_kunga_msk_2022** | Mixed | Pediatric Pancan Tumors (MSK, Nat Commun. 2022) | 135 | 2022 |
| **pancan_mappyacts_2022** | Mixed | Pediatric European MAPPYACTS Trial (Gustave Roussy, Cancer Discov 2022) | 786 | 2022 |
| **lgg_ctf_synodos_2025** | Low-Grade Glioma | Pediatric Low-Grade Glioma (CTF, Acta Neuropathol 2021) | 31 | 2021 |
| **brain_cptac_2020** | Brain | Pediatric Brain Cancer (CPTAC/CHOP, Cell 2020) | 218 | 2020 |
| **pancan_ped_mai_msk_2025** | Mixed | Pediatric Tumors (MSK, 2025) | 60 | 2025 |

**Key observations:**
- **9 studies** published in the last 5 years
- **Largest cohorts:** St. Jude AML (887 samples) and MAPPYACTS (786 samples)
- **Most common types:** Mixed/pan-cancer studies (4) followed by leukemia and solid tumors
- **Recent additions:** MSK and St. Jude studies dominate the 2023–2024 publications
- **Institutional sources:** St. Jude, MSK, CPTAC, and European consortia (Gustave Roussy, UTHSA)
