Systemic relapses of primary CNS lymphomas (PCNSL): a LOC network study.

Primary central nervous system lymphomas (PCNSLs) classically remain confined within the CNS throughout their evolution for unknown reasons. Our objective was to analyse the rare extracerebral relapses of PCNSL in a nationwide population-based study. We retrospectively selected PCNSL patients who experienced extracerebral relapse during their follow-up from the French LOC database.

Management and outcome of primary CNS lymphoma in the modern era: An LOC network study.

Objective: Real-life studies on patients with primary CNS lymphoma (PCNSL) are scarce. Our objective was to analyze, in a nationwide population-based study, the current medical practice in the management of PCNSL.

Methods: The French oculo-cerebral lymphoma network (LOC) database prospectively records all newly diagnosed PCNSL cases from 32 French centers.

[Extranodal NK/T-cell lymphoma, nasal-type, revealed by cutaneous breast involvement].

Background: Extranodal NK/T-cell lymphoma (ENKTL) is a rare form of non-Hodgkin's lymphoma and carries a poor prognosis. Depending on the primary sites of anatomical involvement, it is subcategorized into nasal or extra-nasal ENKTL. Cutaneous involvement is the second localization reported for these lymphomas.

Allogeneic hematopoietic stem cell transplant for hematological malignancies from mismatched 9/10 human leukocyte antigen unrelated donors: comparison with transplants from 10/10 unrelated donors and human leukocyte antigen identical siblings.

We studied the outcome of 213 patients who received allo-HSCT for hematological malignancies, 121 (57%) from HLA identical siblings, 63 (29%) from 10/10 HLA identical unrelated donors and 29 (14%) from 9/10 HLA mismatched unrelated donors. Engraftment was lower in the 9/10 HLA group (90%) than in the 10/10 HLA group (95%) than in the sibling group (99%); 3 months CI of aGVHD ≥ 2 was 32% (23-41), 20% (15-26) and 27% (23-32) respectively; the one year CI of extensive cGVHD was 21% (13-30), 9% (5-13) and 17% (14-21) respectively. The median OS was 10 months (5-21), 18 months (11-NR) and 60 months (31-NR) respectively with 2-years probability of 19% (8-44), 43% (31-59) and 63% (54-74) respectively.

Efficacy and safety profile of long-term exposure to lenalidomide in patients with recurrent multiple myeloma.

Background: Lenalidomide in combination with dexamethasone (Len/Dex) is indicated for patients with recurrent/refractory multiple myeloma (RRMM) who were treated with 1 prior therapy until evidence of disease progression. The objective of the current study was to determine the efficacy and safety profile of long-term exposure to Len/Dex.

Methods: A total of 50 patients with RRMM who were treated with long-term Len for ≥ 2 years from 2 Intergroupe Francophone du Myélome (IFM) centers (Lille and Nancy) were included in the current study.
