Hairy cell leukemia: a successful model for experimental therapeutics--pentostatin and new ideas.
|
| Abstract |
Hairy cell leukemia (HCL) was once considered an untreatable form of chronic lymphoid malignancy. Based upon the recognition of the importance of adenosine deaminase to the normal B cell survival and proliferation, a hypothesis was developed that temporary inhibition of this enzyme might be therapeutically successful in treating chronic B cell leukemias. Pentostatin was initially explored in patients with refractory chronic lymphocytic leukemia (CLL). Both pentostatin and cladribine, purine nucleoside analogs, have been utilized to successfully treat HCL. The high degree of complete and durable remission observed with either agent resulted in many believing that the treatment of this rare disease had been fully optimized. However, a considerable number of patients will relapse. While tremendous progress has been made in initial management, the issues related to optimal therapy, timing of initiation of treatment, and discovery of novel agents that may be effective in those who have relapsed are important. Investigational agents currently being explored in chronic lymphocytic leukemia may also have benefit for those patients who have relapsed or are resistant to therapy of hairy cell leukemia. Many important questions remain (e.g. importance of minimal residual disease) and will require international collaboration to fully address these unanswered questions. The Hairy Cell Leukemia Consortium was established to address these unanswered questions.
