Overview
B-cell prolymphocytic leukemia is a more aggressive, but still treatable, form of chronic lymphocytic leukemia. The malignant B cells are larger than average. The name is commonly abbreviated B-PLL.
It can involve deletions from chromosome 11 and chromosome 13.[1]
It has a relatively poor prognosis.[2]
Markers
A case has been described as CD20+, CD22+, and CD5-.[3]
It can also be CD5+.[4]
Another case was described as CD45+, CD19+, CD20+, CD5+, HLA-DR+, CD10-, CD23+/-, CD38+ and FMC7-.[5]
Diferential Diagnosis
- Hairy cell leukemia
- Waldenström macroglobulinemia
Treatment
- Splenic irradiation has been used in the treatment.[6]
- Cladribine (2-chlorodeoxyadenosine) appears to be an active agent (60% complete remission rate) for patients with de novo B-cell prolymphocytic leukemia.[7]
