Abstract Background Atypical teratoid rhabdoid tumours (ATRT) are aggressive brain tumours mostly occurring in early childhood. Largest published series arise from registries and institutional experiences (1–4). The aim of this report is to provide population-based data to further characterise this rare entity and to delineate prognostic factors. Patients and methods A national retrospective study of children ⩽18 years diagnosed with a central nervous system (CNS) ATRT between 1995 and 2007 was undertaken. All cases underwent central pathology review. Results There were 50 patients (31 males; median age at diagnosis of 16.7 months). Twelve patients were >36 months. Infratentorial location accounted for 52% of all cases. Nineteen patients (38%) had metastatic disease. Fifteen (30%) underwent gross total resection (GTR). Ten patients (20%) underwent palliation. Among the 40 remaining patients, 22 received conventional chemotherapy and 18 received high dose chemotherapy regimens (HDC); nine received intrathecal chemotherapy and 15 received adjuvant radiation. Thirty of the 40 treated patients relapsed/progressed at a median time of 5.5 months (0–32). The median survival time of the entire cohort was 13.5 months (1–117.5 months). Age, tumour location and metastatic status were not prognostic. Patients with GTR had a better survival (2 years overall survival (OS): 60% ± 12.6 versus 21.7% ± 8.5, p = 0.03). HDC conferred better outcome (2 years OS 47.9% ± 12.1 versus 27.3% ± 9.5, p = 0.036). Upfront radiation did not provide survival benefit. Six of the 12 survivors (50%) did not receive radiation. Conclusion The outcome of CNS ATRT remains poor. However, the use of HDC provides encouraging results. GTR is a significant prognostic factor. The role of adjuvant radiation remains unclear.
