Potential breakthroughs with investigational drugs for hairy cell leukemia

摘要

Introduction: Hairy cell leukemia (HCL) is a rare subtype of B-cell chronic lymphoid leukemia. It is characterized by progressive pancytopenia, splenomegaly and infiltrations of the bone marrow, liver and spleen. Over the last few years, several new immunological drugs, particularly immunotoxins, BRAF inhibitors and B-cell receptor (BCR) pathway inhibitors have been developed and investigated as potential treatment options.
