Flow-cytometry-based evaluation of peripheral blood lymphocytes in prognostication of newly diagnosed DLBCL patients

Lymphopenia, the decreased absolute number of T cells, Tregs, and a percentage of apoptotic cells, correlates with clinical staging in DLBCL patients. The increased number of B cells and the decreased level of Tregs and apoptotic cells after treatment might predict a poor clinical outcome in patients treated with RCHOP. Thereby, flow-cytometry-based evaluation of peripheral blood lymphocytes may be useful in prognostication of newly diagnosed DLBCL patients.
