Prolymphocytic leukemia: Treatment with combination chemotherapy to include doxorubicin

Salvage chemotherapy with pentostatin in prolymphocytic leukemia.

We report 4 cases of prolymphocytic leukemia (PLL) resistant to conventional chemotherapy that were treated with pentostatin. We obtained 1 complete remission (CR) and 2 partial remissions (PR). Our data confirm the effectiveness of this drug in the treatment of prolymphocytic leukemia.

Treatment of prolymphocytic leukemia.

Prolymphocytic leukemia is characterized by marked splenomegaly, distinctive cellular morphologic characteristics, and a poor clinical course. Five patients with typical PL were treated systematically with vincristine/prednisone, chlorambucil/prednisone, splenic irradiation, splenectomy, and other chemotherapy regimens. No patient responded to vincristine/prednisone. Two patients responded to c...

A brief intensive chemotherapy in T-prolymphocytic leukemia.

Cytogenetic studies on prolymphocytic leukemia. II. T cell prolymphocytic leukemia.

We report chromosome abnormalities in 15 cases of T cell prolymphocytic leukemia (T-PLL). All cases were characterized by clinical, morphological, and membrane marker analysis. The most frequent abnormality was an inv(14)(q11q32) observed in nine cases. The T cell receptor (TCR) alpha chain gene is localized to 14q11 and the immunoglobulin heavy-chain gene to region 14q32. Four cases also had t...

T-cell Prolymphocytic Leukemia.

BACKGROUND: T-cell prolymphocytic leukemia (T-PLL) is a post-thymic T-cell malignancy with aggressive clinical course. Although T-PLL has been referred to under different designations, it is a distinct clinico-biological entity and should be distinguished from other T-cell disorders. METHODS: The literature on T-PLL is reviewed. Experience on the clinical and laboratory features, differential d...
