Chimeric antigen receptor T-cell therapy (CART) has replaced salvage immunochemotherapy followed by high-dose chemotherapy and autologous stem cell transplantation (HDT-ASCT) as the preferred second-line treatment for early relapsed (< 12 months) large B-cell lymphoma (LBCL). However, for patients with a late relapse (> 12 months), CART is inaccessible until third line. We analyzed 877 patients from the HemoBase registry (diagnosed 2005-2020) to assess differences in long-term outcomes of early versus late relapse in second line. Early relapse occurred in 120/654 patients (18%) who completed first-line treatment, with 2- and 5-year overall survival...

The optimal treatment of patients with breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) that underwent incomplete resection, have advanced stage disease or relapse after resection remains unknown. We describe the treatment and outcome of all 91 Dutch BIA-ALCL patients up to 2023. Primary outcomes were progression-free survival (PFS) and overall survival (OS). Ann Arbor stage I was frequently encountered (74%) compared to stage II (13%) and stage IV (11%). First-line treatment of stage I patients consisted mostly of surgery (88%). Stage II patients were treated with chemotherapy (CT)...

Peripheral T-cell lymphomas (PTCL) comprise a heterogeneous group of 15 different neoplasms in adults. In Europe and North America, PTCL not otherwise specified (PTCL NOS), nodal T follicular helper lymphoma, angioimmunoblastic type (nTFHL-AI), and anaplastic large cell lymphoma (ALCL) either anaplastic lymphoma kinase (ALK) positive (+) or negative (-) are the most prevalent PTCLs. Relapsed or refractory disease (R/R) is common in PTCL and its management is challenging. Despite response rates and prognoses being disease specific, the outcome of R/R PTCL is dismal except for R/R ALK+ ALCL....

Given the rarity of primary central nervous system lymphoma (PCNSL), evaluations of different high-dose methotrexate-(HD-MTX)-based treatment regimens is sparse. This retrospective, multicenter study evaluates clinical characteristics and outcomes (progression-free, overall and disease-specific survival) after five HD-MTX-based polychemotherapeutic regimens and two consolidation therapies. 346 patients with histologically confirmed PCNSL, treated with ≥ 1 cycle HD-MTX-based strategies (≥3g/m2/cycle) were included. The regimens included MATRIX (HD-MTX, HD-AraC, thiotepa, and rituximab), (R)MBVP±HD-AraC (HD-MTX, teniposide/etoposide, carmustine, prednisolone, ± HD-AraC, ± rituximab), (R)MP (HD-MTX, procarbazine, ± rituximab), and a combination of HD-MTX and HD-AraC....

INTRODUCTION: Enteropathy-associated T-cell lymphoma (EATL) is a peripheral T-cell lymphoma (PTCL) with a poor prognosis. Cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) with or without etoposide consolidated by autologous stem cell transplantation (ASCT) are recommended for fit PTCL patients. The role of etoposide and ASCT in EATL is unclear. METHODS: This study reports the incidence, treatment, and outcome of EATL patients using the Netherlands Cancer Registry, with nationwide coverage of >95%. RESULTS: All patients diagnosed in 1989-2021 (n = 351, 77% treated) were identified (median age 67 years, 56%...
