To assess the prognosis of overt testicular disease (OTD) at diagnosis of acute lymphoblastic leukemia (ALL), we analyzed the outcome of 1,165 boys enrolled in EORTC trial 58881. Thirteen (1.1%) boys had OTD associated with bad prognostic features. Patients with and without OTD did not differ in event-free survival (EFS) (P = 0.30) or overall survival (OS) (P = 0.54), even after adjustment for the three most important independent factors (NCI risk group, presence of very high risk features, type of asparaginase used). OTD was not an independent prognostic factor. These results may be due to the use of risk-adjusted intensive chemotherapy comprising high-dose methotrexate.
