What was measured

The primary endpoint is to compare the two-year progression-free survival (PFS) of patients treated with the myeloablative consolidation treatment strategy of HDT/ASCT versus those treated with non-myeloablative consolidation chemotherapy with cytarabine and etoposide. PFS time = time from Registration to earliest date of Progression or Death due to any cause, censoring non-progressed and alive patients at the date of last disease status evaluation. Response will be defined using the modified IPCG criteria. Progressive disease is defined as \> 25% increase in contrast-enhancing CNS (brain and spine if latter abnormal at baseline) disease, appearance of any new, measurable (\>/= 10mm) contrast-enhancing disease or recurrent or new ocular or CSF disease.
