Treatment of Diffuse Large B-Cell Lymphoma.

Project description:Diffuse large B-cell lymphoma (DLBCL) comprises a heterogeneous group with pathophysiological, genetic and clinical features. Many patients can be cured with R-CHOP therapy, which is the current standard regimen. Despite recent progress in improving patient survival, the 40% survival of DLBCL patients remains poor. Therefore, the most important issue for patients with DLBCL remains the development of a new front-line therapy. Several studies have reported that intensified chemotherapy with dose-adjusted EPOCH-R or R-ACVBP was superior to R-CHOP. Gene expression profiling has identified two distinct forms of DLBCL: activated B cell-like (ABC) and germinal center B-cell-like (GCB) types. ABC DLBCL exhibits a worse prognosis than GCB DLBCL by molecular diagnosis after R-CHOP therapy. Next-generation sequencing has identified unique oncogenic mechanisms and genetic complexity, which has provided rational therapeutic targets. There are also a number of biomarkers, including CD5, and prognostic factors. Efforts to distinguish many biomarkers will be crucial for individualized treatment in the future.

Frontline polatuzumab vedotin for diffuse large B-cell lymphoma: A survey of clinician impressions.

Project description:In the POLARIX trial, pola-R-CHP demonstrated improved progression-free survival (PFS) compared to R-CHOP in untreated intermediate- to high-risk DLBCL. We surveyed practicing clinicians regarding their interpretation of POLARIX, including impressions of efficacy, safety, and cost. Of 174 respondents, most from academic centers (82%) in the United States (57%), 70% stated they would not replace R-CHOP with pola-R-CHP due to insufficient PFS difference, lack of overall survival benefit, and excessive cost. Respondents not recommending pola-R-CHP expressed concerns about financial implications for both society and patients. We observed considerable heterogeneity in both study interpretation and plans for real-world implementation of pola-R-CHP.

Mutational Evolution in Relapsed Diffuse Large B-Cell Lymphoma.

Project description:Current genomic models in diffuse large B-cell lymphoma (DLBCL) are based on single tumor biopsies, which might underestimate heterogeneity. Data on mutational evolution largely remains unknown. An exploratory study using whole exome sequencing on paired (primary and relapse) formalin fixed paraffin embedded DLBCL biopsies (n = 14) of 6 patients was performed to globally assess the mutational evolution and to identify gene mutations specific for relapse samples from patients treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone. A minority of the mutations detected in the primary sample (median 7.6%, range 4.8⁻66.2%) could not be detected in the matching relapse sample. Relapsed DLBCL samples showed a mild increase of mutations (median 12.5%, range 9.4⁻87.6%) as compared to primary tumor biopsies. We identified 264 genes possibly related to therapy resistance, including tyrosine kinases (n = 18), (transmembrane) glycoproteins (n = 73), and genes involved in the JAK-STAT pathway (n = 7). Among the potentially resistance related genes were PIM1, SOCS1, and MYC, which have been reported to convey a risk for treatment failure. In conclusion, we show modest temporal heterogeneity between paired tumor samples with the acquisition of new mutations and identification of genes possibly related to therapy resistance. The mutational evolution could have implications for treatment decisions and development of novel targeted drugs.

T-Cell Engaging Antibodies in Diffuse Large B Cell Lymphoma-An Update.

Project description:Novel cellular immunotherapies such as T-cell engaging antibodies (TCEAbs) are changing the landscape of treatment for diffuse large B cell lymphoma (DLBCL), especially in the relapsed/refractory (R/R) setting. TCEAbs harness the power of the host immune system to induce killing of tumor cells by binding to both the tumor antigen and the T-cell receptor. Since the approval of blinatumomab for R/R acute lymphoblastic leukemia, there has been significant development in novel TCEAbs. Many of these novel TCEAbs have shown promising effectiveness in R/R DLBCL, with favorable response rates including complete remissions, even in heavily pretreated patients. There are unique therapy-related toxicities with TCEAbs, namely cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity (ICANS), and it is important to both recognize and manage these side effects appropriately. This review examines the development and mechanism of action of these TCEAbs, and the available published data from clinical trials. Their role in the treatment of DLBCL, the management of therapy-related adverse events, and the mechanisms of resistance will also be discussed.

Lymphoplasmacytic lymphoma associated with diffuse large B-cell lymphoma: Progression or divergent evolution?

Project description:AimLymphoplasmacytic lymphoma (LPL) is an indolent mature B-cell-neoplasm with involvement of the bone marrow. At least 90% of LPLs carry MYD88-L265P mutation and some of them (~10%) transform into diffuse large B-cell-lymphoma (DLBCL).Material and methodsOver the past 15 years we have collected 7 cases where the both LPL and DLBCL were diagnosed in the same patient. Clinical records, analytical data and histopathological specimens were reviewed. FISH studies on paraffin-embedded tissue for MYC, BCL2 and BCL6 genes were performed, as well as MYD88-L265P mutation and IGH rearrangement analysis by PCR. A mutational study was done by massive next generation sequencing (NGS).ResultsThere were 4 women and 3 men between 36-91 years of age. Diagnoses were made simultaneously in 4 patients. In two cases the LPL appeared before the DLBCL and in the remaining case the high-grade component was discovered 5 years before the LPL. In 6 cases both samples shared the MYD88-L265P mutation. IGH rearrangement analysis showed overlapping features in two of 6 cases tested. Mutational study was evaluable in three cases for both samples showing shared and divergent mutations.ConclusionsThese data suggest different mechanisms of DLBCL development in LPL patients.

FCGR3A 158V/F polymorphism and response to frontline R-CHOP therapy in diffuse large B-cell lymphoma.

Project description:The influence of Fc gamma receptor IIIA (FCGR3A) 158V/F polymorphisms on the response to rituximab (R) plus CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone; R-CHOP) therapy in diffuse large B-cell lymphoma (DLBCL) is uncertain. Thus, a retrospective study and a meta-analysis were performed to examine the possible correlation between FCGR3A 158V/F polymorphism and the response rate of R-CHOP regimen in patients with newly diagnosed DLBCL. The genotypes of FCGR3A 158V/F in 164 newly diagnosed DLBCL patients treated with R-CHOP were determined in this retrospective study. Additionally, a meta-analysis of current and previously published studies was conducted. Overall response rate (complete and partial response, ORR) and complete response rate (CR) were evaluated. The results of our retrospective study showed lack of correlation between FCGR3A 158V/F polymorphism and ORR (p=0.78) or CR (p=0.76) with R-CHOP therapy. A meta-analysis of 731 cases also showed lack of significant association of ORR and CR in all genetic models with FCGR3A 158V/F polymorphism. In survival analysis, the homozygous F genotype correlated with a shorter progression-free survival than that of non-F/F genotype (p=0.05), this was significant for the non-GC subset of DLBCL (p=0.04), but no association was found between overall survival and FCGR3A 158V/F polymorphism. Further analysis with nonsuperiority test (p<0.0001) suggested that FCGR3A 158V/F polymorphism was not associated with better ORR or CR in newly diagnosed DLBCL patient treated with R-CHOP. No clear relationship was found between FCGR3A 158V/F polymorphism and response to frontline R-CHOP therapy in patients with DLBCL.

Development of follicular lymphoma after treatment of diffuse large B-cell lymphoma: two case reports with review of literature.

Project description:Diffuse large B-cell lymphoma (DLBCL) is one of the most frequent subtypes of aggressive lymphomas, which can be transformed lymphoma that mostly develops from other types of lymphoma. Cases of DLBCL arising developing after the initial diagnosis of follicular lymphoma (FL) have been reported. However, until now, little few studies have been reported were conducted on the patients with DLBCL and with subsequent development of FL in patients with DLBCL. Here we presented this study with two rare cases of, namely, FL and Composite concurrently occurs with DLBCL and FL developing after the initial diagnosis of DLBCL. In order to investigate the clinical and molecular features of patients with DLBCL and FL, we also reviewed the literature on FL patients with FL developing DLBCL, and patients with composite FL and DLBCL.

2021 Update on Diffuse large B cell lymphoma: A review of current data and potential applications on risk stratification and management.

Project description:Diffuse large B cell lymphoma (DLBCL), the most common type of Non-Hodgkin lymphoma (NHL), comprises a heterogeneous group of diseases with different biology, clinical presentations, and response to treatment. R-CHOP remains the mainstay of therapy and can achieve long-term disease control in nearly 90% of patients presenting with limited-stage and in up to 60% of those presenting with advanced stages. Advances on the understanding of the genetic landscape and molecular features of DLBCL have identified high-risk subsets with poor outcomes to chemo-immunotherapy that are actively being studied in clinical trials. Novel therapies could potentially improve outcomes for patients with high-risk disease. Studies evaluating risk-adapted therapy based on classification by cell of origin (COO) and molecular features are ongoing. Developments in the fields of immunotherapy, mostly with adoptive T-cell therapy, have significantly improved the outcomes of patients with relapsed refractory disease. In this review, we will summarize the recent data and discuss ongoing efforts to improve DLBCL treatment in the frontline and relapsed refractory settings.

Recent Update of HDAC Inhibitors in Lymphoma.

Project description:Modulating epigenetic modification has been recognized for over a decade as an effective therapeutic approach to cancer and many studies of histone deacetylase (HDAC), one of the best known epigenetic modulators, have been published. HDAC modulates cell proliferation and angiogenesis and plays an essential role in cell growth. Research shows that up-regulated HDACs are present in many cancer types and synthetic or natural HDAC inhibitors have been used to silence overregulated HDACs. Inhibiting HDACs may cause arrest of cell proliferation, angiogenesis reduction and cell apoptosis. Recent studies indicate that HDAC inhibitors can provide a therapeutic effect in various cancers, such as B-cell lymphoma, leukemia, multiple myeloma and some virus-associated cancers. Some evidence has demonstrated that HDAC inhibitors can increase the expression of immune-related molecules leading to accumulation of CD8 + T cells and causing unresponsive tumor cells to be recognized by the immune system, reducing tumor immunity. This may be a solution for the blockade of PD-1. Here, we review the emerging development of HDAC inhibitors in various cancer treatments and reduction of tumor immunity.
