Treatment of high risk medulloblastomas in children above the age of 3 years: a SFOP study.
2006
Abstract Aim Improvement of EFS of children older than 3 years with high risk medulloblastoma. Methods Between 1993 and 1999, 115 patients (3–18 years, mean 8 years) with high risk medulloblastoma were included. After surgery treatment consisted of chemotherapy (‘8in1’ and etoposide/carboplatin) before and after craniospinal radiotherapy. Results Patients were staged using Chang-criteria (PF residue only, M1 and M2/M3) by local investigator as well as by central review panel (82.4% concordance). Chemotherapy was well tolerated without major delays in radiotherapy. With a mean follow up of 81 months (9–119), 5-year EFS was 49.8% and OS 60.1%. In detail according to subgroups EFS was 68.8% for PF residue only, 58.8% for M1 disease and 43.1% for M2/M3. Conclusion M1 patients are legitimate high risk patients. Survival rates are still very low for high risk medulloblastoma patients and future trials should therefore focus on more intensive (chemotherapy/radiotherapy) treatment.
