═ answer (success)
Based on the study names, which include publication years, here are the pediatric cancer studies published in the last 5 years (2021–2026):

| Study | Study ID | Cancer Type | Samples |
|---|---|---|---|
| [Pediatric Tumors (MSK, 2025)](https://www.cbioportal.org/study/summary?id=pancan_ped_mai_msk_2025) | `pancan_ped_mai_msk_2025` | Mixed solid/CNS tumors | 60 |
| [Pediatric Low-Grade Glioma (CTF, Acta Neuropathol 2021)](https://www.cbioportal.org/study/summary?id=lgg_ctf_synodos_2025) | `lgg_ctf_synodos_2025` | Low-grade glioma (with NF) | 31 |
| [Pediatric Acute Myeloid Leukemia (St. Jude, Nat Genet 2024)](https://www.cbioportal.org/study/summary?id=aml_stjude_2024) | `aml_stjude_2024` | AML | 887 |
| [Pediatric European MAPPYACTS Trial (Gustave Roussy, Cancer Discov 2022)](https://www.cbioportal.org/study/summary?id=pancan_mappyacts_2022) | `pancan_mappyacts_2022` | Mixed (multiple pathologies) | 786 |
| [Pediatric solid tumor PDXs (UTHSA, Nat Commun 2023)](https://www.cbioportal.org/study/summary?id=pancan_pdx_uthsa_2023) | `pancan_pdx_uthsa_2023` | Mixed solid tumors (PDX) | 136 |
| [Pediatric Pancan Tumors (MSK, Nat Commun 2022)](https://www.cbioportal.org/study/summary?id=mixed_kunga_msk_2022) | `mixed_kunga_msk_2022` | Mixed tumors | 135 |
| [Pediatric Neuroblastoma (MSK, Nat Genet 2023)](https://www.cbioportal.org/study/summary?id=nbl_msk_2023) | `nbl_msk_2023` | Neuroblastoma | 223 |
| [Pediatric Rhabdomyosarcomas (MSK, JCO Precis Oncol 2023)](https://www.cbioportal.org/study/summary?id=rms_msk_2023) | `rms_msk_2023` | Rhabdomyosarcoma | 24 |

**Notes:**
- The study name for `lgg_ctf_synodos_2025` cites "Acta Neuropathol 2021" as the original publication, despite the "2025" suffix in its identifier (which likely reflects a data reprocessing/reload date). I've included it, but flag this discrepancy — the underlying publication is 2021, which is right at the edge of the 5-year window.
- I excluded TARGET (2018), DKFZ (2017), PPTC (2019), CPTAC/CHOP (2020), and older studies (2012–2017) as they fall outside the 2021–2026 window.
- This list is based on the publication year embedded in each study's name/description, not a database "publication date" field — cBioPortal does not store a separate structured publication date column.

Would you like me to open any of these in the cBioPortal Study View for a closer look, or narrow this list to a specific cancer type (e.g., only leukemias, only solid tumors)?
