Study for Treatment of Cancer in Children With Ataxia-telangiectasia

Pilot Study I for Treatment of Cancer in Children With Ataxia-Telangiectasia

This is a pilot/feasibility study designed to investigate the feasibility of treating children with Ataxia-Telangiectasia (A-T) and cancer with regimens nearly as intense as non-A-T patients with cancer would receive.

Study Overview

• Status: Completed
• Conditions: Ataxia-Telangiectasia
• Intervention / Treatment: Drug: vinblastine, vincristine, prednisone, daunorubicin; Drug: doxorubicin, methotrexate, cyclophosphamide, L-asparaginase; Drug: etoposide, cytarabine, mercaptopurine; Drug: dexamethasone, procarbazine; Procedure: chemotherapy, intrathecal chemotherapy, steroid therapy

Detailed Description

Approximately 10-30% of A-T patients will develop a malignancy during their lifetime. The vast majority of these cancers are of lymphoid origin. There is no consensus regarding the optimal strategy for treating children with A-T who develop hematopoietic malignancies. Historically, many of these children have been treated with therapy that is much less intensive than the conventional approach for non-A-T patients with similar malignancies during the corresponding treatment era. Although these less intensive approaches may have stemmed from perceptions that these children would not tolerate intensive therapy, there is in fact no data to suggest that these children cannot tolerate intensive therapy. However, it is clear that children with A-T require a modification in certain components of intensive therapy.

To provide children with A-T and either ALL or malignant lymphoma the best chance for a cure, we propose to use modern therapeutic strategies with minimal modifications which address the unique toxicity profile encountered in treating children with A-T.

Secondary objectives include:

• To clinically and biologically characterize the malignancies occurring in children with A-T (usually malignant lymphoma or ALL). This will include in vitro drug sensitivity screening.
• To study chemotherapy-induced DNA damage in children with A-T.
