SMNs in children treated for GCTs was assessed in the Malignant Germ Cell Tumor International Consortium data commons (\n                    <jats:italic>n<\/jats:italic>\n                    \u00a0=\u00a0917). Thirteen SMNs were identified with median follow\u2010up of only 5.9 years. Assigning cause is nuanced because GCT\u2010related SMNs can either be treatment related, second primary malignancies from a common primordial germ cell progenitor, or somatic malignant transformation of the original GCT. Longer follow\u2010up of children with GCT is needed to ascertain risk and understand causation.\n                  <\/jats:p>","DOI":"10.1002\/1545-5017.70206","type":"journal-article","created":{"date-parts":[[2026,3,16]],"date-time":"2026-03-16T05:43:58Z","timestamp":1773639838000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Second Malignancies in Children and Adolescents With Extracranial Germ Cell Tumors: A Report From the Malignant Germ Cell Tumor International Consortium"],"prefix":"10.1002","volume":"73","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6710-5865","authenticated-orcid":false,"given":"Priya","family":"Mahajan","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Section of Hematology\/Oncology Seattle Children's Hospital, University of Washington  Seattle Washington USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark","family":"Krailo","sequence":"additional","affiliation":[{"name":"University of Southern California Keck School of Medicine  Los Angeles California USA"},{"name":"Statistics and Data Center Children's Oncology Group  Monrovia California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Negar","family":"Fallahazad","sequence":"additional","affiliation":[{"name":"Statistics and Data Center Children's Oncology Group  Monrovia California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michelle","family":"Nuno","sequence":"additional","affiliation":[{"name":"University of Southern California Keck School of Medicine  Los Angeles California USA"},{"name":"Statistics and Data Center Children's Oncology Group  Monrovia California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brice","family":"Fresneau","sequence":"additional","affiliation":[{"name":"Department of Children and Adolescents Oncology Gustave Roussy, Universit\u00e9 Paris\u2010Saclay  Villejuif France"},{"name":"Universit\u00e9 Paris\u2010Saclay, UVSQ, Inserm, CESP  Villejuif France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sara","family":"Stoneham","sequence":"additional","affiliation":[{"name":"Children and Young Peoples Cancer Services, University College London Hospital  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.
