Summary
This study reports on 18 hairy cell leukemia patients. Splenectomy is the primary treatment, often improving pancytopenia and leading to long survival, despite persistent bone marrow infiltration.
Area of Science:
- Hematology
- Oncology
Background:
- Hairy cell leukemia (HCL) presents with homogeneous clinical features but is often misdiagnosed.
- Diagnostic challenges include variable peripheral blood "hairy" cell counts and unclear causes of pancytopenia.
Purpose of the Study:
- To report on the long-term follow-up of 18 patients with hairy cell leukemia.
- To describe diagnostic and therapeutic modalities for HCL.
- To evaluate the effectiveness of splenectomy and other treatments.
Main Methods:
- Retrospective analysis of 18 HCL patients.
- Review of diagnostic methods, including bone marrow biopsy.
- Assessment of treatment outcomes, including splenectomy, chemotherapy, and splenic irradiation.
Main Results:
- Bone marrow biopsy was diagnostic in 17/17 patients pre-splenectomy.
- Splenectomy led to amelioration of pancytopenia in most patients.
- Treatment responses to chemotherapy and splenic irradiation were variable.
Conclusions:
- Splenectomy is the established therapy for hairy cell leukemia.
- Despite persistent bone marrow infiltration post-splenectomy, patients often experience long, uncomplicated survival.
- No pre-splenectomy clinical features predicted surgical response.
