Lymphopenia as a prognostic factor in patients with peripheral T-cell lymphoma, unspecified.
نویسندگان
چکیده
Peripheral T-cell lymphoma, unspecified (PTCLU) is the most common T-cell lymphoma variant. The molecular heterogeneity of PTCLU is reflected by a diverse clinical course. Several prognostic factors have been studied, but further refinement is needed. The aim of our study was to retrospectively evaluate the presence of lymphopenia, defined as a lymphocyte count of<1000 cells/mm³, as a prognostic factor for survival in patients with PTCLU. Sixty-nine cases with a pathological diagnosis of PTCLU were included in our analysis. Lymphopenia was seen in 38% of the patients and was statistically associated with a worse response to chemotherapy. In univariate analysis, lymphopenia, IPI score>2, and Prognostic Index for PTCLU (PIT) score>2 were associated with a worse overall survival. In multivariate analysis, lymphopenia and a PIT score>2 were the only independent poor prognostic factors, implying an important role of the patient's immune system in both response to therapy and survival.

Lymphopenia is an important prognostic factor in peripheral T-cell lymphoma (NOS) treated with anthracycline-containing chemotherapy
BACKGROUND Peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) is a heterogeneous group of aggressive T-cell lymphomas with poor treatment outcomes. The aim of this study was to evaluate whether lymphopenia at diagnosis would have an adverse effect on survival in patients with PTCL-NOS treated with anthracycline-containing chemotherapy. METHODS A total of 118 patients with PTCL-NOS...

Objective To determine the efficacy and prognosis of autologous hematopoietic stem cell transplantation (ASCT) as frontline treatment for peripheral T cell lymphoma (PTCL). Methods Clinical data from 46 PTCL patients who achieved complete (CR) or partial remission (PR) after ASCT from October 1996 to July 2014 were analysed retrospectively. Results Median patient age was 32 (range: 15-68) years...
متن کاملExpression of nm23-H1 is associated with poor prognosis in peripheral T-cell lymphoma.
We have reported previously that the serum nm23-H1 level is a prognostic factor for non-Hodgkin's lymphoma. In this study, we examined nm23-H1 expression in T- and natural killer (NK)-cell lymphoma in order to evaluate whether lymphoma cells produce the protein. The clinical significance of the cytotoxic molecules, T-cell intracellular antigen-1 (TIA-1) and granzyme B and nm23-H1 expression wer...
متن کاملPeripheral T-cell Lymphoma of the Uvula: A Rare Entity
Abstract Introduction: Extra-nodal exposition of T-cell non-hodgkin lymphoma (NHL) is extremely rare, and is frequently observed in patients with immune system dysfunction. Peripheral T-cell lymphoma does not express CD56 is rare. Malignant lymphoma of the uvula is exceedingly unusual. The current study reported a case of peripheral T-cell lymphoma of the uvula in an immunecompetent patient. ...
