Successful Treatment of Adolescents and Young Adults with Philadelphia-Negative Acute Lymphoblastic Leukemia by Novel L-Asparaginase-Intensified Induction Therapy and Cord Blood Transplantation: A Single-Center Decade Report.

A novel induction therapy, including intensive L-asparaginase, was designed in 2007 for patients aged <45 years with Philadelphia-negative acute lymphoblastic leukemia (ALL). We analyzed seven de novo cases and one case of recurrence who received this treatment. The median age was 21 years (range: 16-35 years). Four patients had T-ALL and the others had B-ALL. All the patients achieved complete remission and proceeded to cord blood transplantation. In the median 72-month follow-up, there were no cases of observed mortality or recurrence. Our results indicate scope for further development of both induction therapy and postremission therapy.
