Rhabdoid tumor predisposition syndrome is usually associated with shorter survival in patients with malignant rhabdoid tumors regardless of anatomical origin. Here we present four children harboring truncating heterozygous SMARCB1/INI1 germline mutations with favorable outcome. All four patients received multi-modality treatment, three according to therapeutic recommendations by the EU-RHAB registry, two without radiotherapy, and mean event-free survival accounts for 7 years. In conclusion, intensive treatment with curative intent is justified for children with rhabdoid tumors even if an underlying rhabdoid predisposition syndrome is demonstrated.
Keywords: SMARCB1 germline mutation; atypical teratoid/rhabdoid tumor; treatment outcome.
