Positron Emission Tomography-Guided Brentuximab Vedotin, Etoposide, Cyclophosphamide, Doxorubicin, Dacarbazine, and Dexamethasone in Older Patients With Advanced-Stage Classic Hodgkin Lymphoma: A Prospective, Multicenter, Single-Arm, Phase II Cohort of the German Hodgkin Study Group HD21 Trial.

Purpose: Positron emission tomography (PET)-guided therapy with 4-6 cycles of brentuximab vedotin, etoposide, cyclophosphamide, doxorubicin, dacarbazine, and dexamethasone (BrECADD) is highly effective in younger patients with advanced-stage classic Hodgkin lymphoma (AS-cHL). We report feasibility and efficacy of PET-guided BrECADD as first-line treatment in older patients with AS-cHL.

Patients And Methods: Patients with AS-cHL aged 61-75 years were enrolled in a phase II single-arm cohort of the HD21 trial (ClinicalTrials.

Nodular Lymphocyte-Predominant Hodgkin Lymphoma: Update on Biology and Treatment.

Nodular lymphocyte-predominant B-cell/Hodgkin lymphoma (NLPB/HL) accounts for roughly 5% of all Hodgkin lymphoma (HL) cases. In contrast to classic HL (cHL), the malignant cells in NLPB/HL lack CD30 expression but maintain a complete phenotype of mature B-cells including CD20 and IgG, but occasionally show IgD expression. The tumor cells are known as lymphocyte-predominant (LP) cells and grow in a T-cell and histiocyte rich microenvironment against a background of follicular dendritic cells.

Refining histopathological growth pattern-based risk group discrimination in nodular lymphocyte-predominant Hodgkin lymphoma: an analysis from the German Hodgkin Study Group.

Histopathological growth patterns (GP) in nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) have previously been divided into GP AB (typical) vs CDEF (variant). However, it is unclear whether this division is optimal. We thus investigated alternative GP grouping approaches (GP ABC vs DEF; GP ABCF vs DE).
