Biological Description of 109 Cases of Blastic Plasmacytoid Dendritic Cell Neoplasm (BPDCN) from the French Network of BPDCN

2015

Abstract Blastic plasmacytoid dendritic cell neoplasm is a clonal disease derived from precursors of plasmacytoid dendritic cells (pDC). It is a rare neoplasm involving the skin which may or may not be associated from the outset with a leukemic component. The disease invariably progresses to aggressive leukemic dissemination, leading to a differential diagnosis with acute leukemia. In 2004, we set up a French network to recruit biological data at diagnosis. Diagnosis was according to recommendations (Swerdlow et al, 2008), with, in addition, a mandatory panel of pDC markers (Garnache-Ottou et al, 2009) detected by flow cytometry or by immunohistochemistry on infiltrated blood, bone marrow o…

Efficacy of bendamustine and rituximab in splenic marginal zone lymphoma: results from the phase II BRISMA/IELSG36 study.

2018

Splenectomy in addition to immunotherapy with rituximab can provide quick and sometimes durable disease control in patients with splenic marginal zone lymphoma (SMZL). However, systemic chemotherapy is ultimately required in many cases. The BRISMA (Bendamustine-rituximab as first-line treatment of splenic marginal zone lymphoma)/IELSG (International Extranodal Lymphoma Study Group)36 trial is an open-label, single arm phase II study designed by the IELSG in cooperation with the Fondazione Italiana Linfomi and the lymphoma Study Association according to Simon's two-stage method. The primary endpoint was complete response rate. Fifty-six patients with SMZL diagnosis confirmed on central revis…
