TPM Regimen (Thalidomide, Prednisone and Methotrexate) in LGLL

Summary

Large granular lymphocytic leukemia (LGLL) is a lymphoproliferative disease, with LGL infiltration in peripheral blood and bone marrow, hepatosplenomegaly, and cytopenia. Both T-LGLL and CLPD-NK are indolent disease and share similar biology and clinical course, and treated under the same strategy. So the investigators put them together as LGLL. The investigators used TPM regimen (thalidomide + prednison + methotrexate ) to treat LGLL since 2013, and 18/20 patients (90%) obtained clinical response, including 80% complete response. Adverse events (AE) of grade 3 and above are rare and safe. Therefore, the investigators designed this multicenter clinical trial to validate the efficacy of the TPM regimen in symptomatic T-LGLL and CLPD-NK.
