Background: Secondary acute lymphoblastic leukemia (sALL) is a rare disease and its biologic features are not well characterized.
Patients and methods: We describe a cohort of seven patients and discuss 94 additional cases from the literature for whom biological parameters were described. Cases with incomplete data were excluded.
Results: Hodgkin's disease (HD) was more common in the 18–59 age group while breast and prostate cancers were prevalent only in the
18-year-old patients. The time interval to develop sALL was similar among all age groups but was significantly longer for HD and neuroblastoma primary diagnoses and sALL with complex karyotype. T-cell immunophenotype was more common in the <18 age group. Complete remission was infrequent in the
60 age group. The overall survival was poor for all sALL regardless of age, primary diagnoses, cytogenetic subgroups, or immunophenotype. Allogeneic transplantation most probably represents the only chance of cure.
Conclusion: Better identification of prognostic factors to prevent the occurrence of sALL is indicated.
Key words: acute lymphoblastic leukemia, 11q23 aberrations, secondary neoplasms
