Utility of CD54, CD229, and CD319 for the identification of plasma cells in patients with clonal plasma cell diseases
2015
Background Multiparameter flow cytometry (MFC) identification and characterization of plasma cells (PCs) is a useful tool to support diagnosis, prognostication, and monitoring of PC diseases (PCD). Currently, the number of MFC markers suited for the identification of PC remains limited. Moreover, antibody therapies against PC-associated markers further compromise the utility of the most widely used reagents (e.g., CD38). Despite markers other than CD38 and CD138 are recognized as potentially useful PC-identification markers, no study has comparatively evaluated their performance in combination with CD38 and CD138. Here we compared the utility of CD229, CD54, and CD319 for the identification…
Residual Abdominal Lymphadenopathy after Intensive Frontline Chemoimmunotherapy Is Associated with Inferior Outcome Regardless of MRD Status in Advan…
2018
Abstract Introduction: In CLL, chemoimmunotherapies (CIT) and combinations with novel agents have proven to be highly effective with regard to eradication of minimal residual disease (MRD), while complete remissions (CR) are frequently not achieved due to residual lymphadenopathy. We have previously reported that minimal residual disease (MRD) negativity after CIT is a prognostic factor irrespective of the clinical response (Kovacs et al., JCO 2016). Because inferior outcome was observed in small subgroups of patients (pts) with residual lymphadenopathy, we analyzed the prognostic value of residual lymphadenopathy after CIT in comparison to MRD detection in a larger pt population. Methods: …

Obinutuzumab plus bendamustine in previously untreated patients with CLL: a subgroup analysis of the GREEN study
2017
GREEN (NCT01905943) is a non-randomized, open-label phase IIIb study investigating obinutuzumab alone or plus chemotherapy in chronic lymphocytic leukemia (CLL). We report a preplanned subgroup analysis of 158 previously untreated CLL patients receiving obinutuzumab–bendamustine (G-B). Patients received six 28-day cycles (C) of G-B: obinutuzumab day (D)1/D2 of C1 (25 mg D1/975 mg D2), 1000 mg D8 and D15 of C1, and D1 of C2–6; and bendamustine 70/90 mg/m2 D1 and D2 of C1–6. The primary endpoint was safety/tolerability. Grade ≥3 adverse events (AEs) occurred in 82.3% of patients, including neutropenia (49.4%), thrombocytopenia (12.0%) and febrile neutropenia (10.8%). Serious AEs included neut…
