High-dose chemotherapy and autologous hematopoietic stem cell transplantation for progressive systemic sclerosis: a retrospective study of outcome and prognostic factors.

Purpose: Systemic sclerosis (SSc) is a rare autoimmune disease associated with high morbidity and mortality. SSc treatment is still challenging, and evidence is scarce. In the last decades high-dose chemotherapy and autologous stem cell transplantation (HD-ASCT) has proven to be effective.

Treatment Strategies and Prognostic Factors in Secondary Central Nervous System Lymphoma: A Multicenter Study of 124 Patients.

Secondary central nervous system lymphoma (SCNSL) is a rare and difficult to treat type of Non-Hodgkin lymphoma characterized by systemic and central nervous system (CNS) disease manifestations. In this study, 124 patients with SCNSL intensively treated and with clinical long-term follow-up were included. Initial histopathology, as divided in low-grade, other aggressive, and diffuse large B-cell lymphoma (DLBCL), was of prognostic significance.

Novel Gene Fusion in Acute Myeloid Leukemia Detected by Optical Genome Mapping.

Optical genome mapping (OGM) recently has demonstrated the potential to improve genetic diagnostics in acute myeloid leukemia (AML). In this study, OGM was utilized as a tool for the detection of genome-wide structural variants and disease monitoring. A previously unrecognized fusion was detected in an adult patient with secondary AML.

Cytotoxicity of CD19-CAR-NK92 cells is primarily mediated via perforin/granzyme pathway.

Chimeric antigen receptors (CARs) have improved cancer immunotherapy in recent years. Immune cells, such as Natural killer cells (NK-cells) or T cells, are used as effector cells in CAR-therapy. NK92-cells, a cell line with known cytotoxic activity, are of particular interest in CAR-therapy since culturing conditions are simple and anti-tumor efficacy combined with a manageable safety profile was proven in clinical trials.

Optical Genome Mapping Reveals and Characterizes Recurrent Aberrations and New Fusion Genes in Adult ALL.

(1) Background: In acute lymphoblastic leukemia (ALL) the genetic characterization remains challenging. Due to the genetic heterogeneity of mutations in adult patients, only a small proportion of aberrations can be analyzed with standard routine diagnostics. Optical genome mapping (OGM) has recently opened up new possibilities for the characterization of structural variants on a genome-wide level, thus enabling simultaneous analysis for a broad spectrum of genetic aberrations.

Optical Genome Mapping for Cytogenetic Diagnostics in AML.

The classification and risk stratification of acute myeloid leukemia (AML) is based on reliable genetic diagnostics. A broad and expanding variety of relevant aberrations are structural variants beyond single-nucleotide variants. Optical Genome Mapping is an unbiased, genome-wide, amplification-free method for the detection of structural variants.

[Novel Treatment Concepts in Patients with Colorectal Carcinomas and High Microsatellite Instability].

Approximately 15% of patients with colorectal cancer show high microsatellite instability (MSI-high) in their tumour tissue. For one third of these patients, there is a hereditary cause for this finding - that leads to the diagnosis of Lynch Syndrome. In combination with clinical findings such as the Amsterdam or the revised Bethesda criteria, MSI-high status has been used as a tool in identifying patients at risk.

Survival, prognostic factors, hospitalization time and clinical performance status after first cerebral relapse or progression in 54 patients with primary CNS lymphoma not eligible for high dose chemotherapy: a retrospective analysis.

Background: Treatment of relapsed or refractory primary CNS lymphoma (r/r PCNSL) is difficult, particularly in patients not eligible for high dose chemotherapy with autologous stem cell transplantation (HDC-ASCT). No standard treatment has been defined for these patients yet.

Methods: We retrospectively analyzed survival, prognostic factors, hospitalization time and Karnofsky performance score (KPS) before and after treatment in 54 r/r PCNSL patients with isolated cerebral relapse or progression (n = 23 refractory, n = 31 relapsed) not eligible for HDC-ASCT, who received heterogenous salvage treatments.

Broad genomic workup including optical genome mapping uncovers a : gene fusion in acute myeloid leukemia.

In acute myeloid leukemia (AML), treatment decisions are currently made according to the risk classification of the European LeukemiaNet (ELN), which is based on genetic alterations. Recently, optical genome mapping (OGM) as a novel method proved to yield a genome-wide and detailed cytogenetic characterization at the time of diagnosis. A young female patient suffered from a rather unexpected aggressive disease course under FLT3 targeted therapy in combination with induction chemotherapy.

Outcome and prognostic factors of very old patients with primary CNS lymphoma: a retrospective analysis of patients ≥80 years treated with high-dose methotrexate-based chemotherapy.

Although >10% of primary CNS lymphoma (PCNSL) patients are ≥80 years, data on this population are limited. We analyzed 19 consecutive octogenarians with PCNSL treated with high-dose methotrexate (HD-MTX)-based chemotherapy at our institution concerning outcome, prognostic factors and living conditions at six-month follow-up for 11 patients alive and in remission. Seven patients received intracerebroventricular (ICV) treatment additional to systemic therapy.

High-Dose Chemotherapy with Autologous Hematopoietic Stem Cell Transplantation in Relapsed or Refractory Primary CNS Lymphoma: A Retrospective Monocentric Analysis of Long-Term Outcome, Prognostic Factors, and Toxicity.

High-dose chemotherapy with autologous stem cell transplantation (HCT-ASCT) is reportedly an effective treatment strategy in relapsed or refractory primary CNS lymphoma (r/r PCNSL); however, only selected patients are eligible for this treatment. We retrospectively analyzed outcome, prognostic factors, and toxicity in 59 patients with r/r PCNSL planned to receive HCT-ASCT at our institution between January 2005 and December 2021 (n = 33 < 65 years; n = 26 ≥ 65 years). Median follow-up was 65 months (95% CI 21−109).

Optical genome mapping reveals additional prognostic information compared to conventional cytogenetics in AML/MDS patients.

Cytogenetic diagnostics play a crucial role in risk stratification and classification of myeloid malignancies such as acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), thus influencing treatment decisions. Optical genome mapping (OGM) is a novel whole genome method for the detection of cytogenetic abnormalities. Our study assessed the applicability and practicality of OGM as diagnostic tool in AML and MDS patients.

Quantification of cell-free DNAfor the analysis of CD19-CAR-T cells during lymphoma treatment.

Chimeric antigen receptor (CAR)-T cells are increasingly used for the treatment of hematologic malignancies. Treatment success relies highly upon sufficient expansion of CAR-T effector cells. Accordingly, longitudinal quantification of CAR-T cells during therapy is clinically important.

Successful Chimeric Antigen Receptor (CAR) T-Cell Treatment in Aggressive Lymphoma Despite Coronavirus Disease 2019 (CoVID-19) and Prolonged Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Replication - Case Report.

In patients with compromised immune function, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and coronavirus disease 2019 (CoVID-19) impose particular challenges. Especially in hematological malignancies, including lymphoma, the demands by this novel virus disease are further enhanced during sophisticated treatments, such as chimeric antigen receptor (CAR) T-cell therapy. Here, we present the first case of a patient with refractory diffuse-large B-cell lymphoma, who underwent CAR T-cell treatment in the context of SARS-CoV-2.
