Current advances in Hodgkin's lymphoma.

ABSTRACT: Hodgkin's lymphoma is a highly treatable malignancy. It has high cure rates yet there are many patients who relapse or are refractory to treatment. Traditionally, treatment has been with conventional chemotherapy; however, the development of brentuximab vedotin and immune checkpoint inhibitors has revolutionized the care of Hodgkin's lymphoma. This is a review of the current advances in the management of Hodgkin's lymphoma and a review of ongoing clinical trials in the field.

Advances in the treatment of relapsed or refractory Hodgkin's lymphoma.

Project description:Hodgkin's lymphoma (HL) is diagnosed in 20,000 men and women annually in North America and Europe. Despite treatment advancements for HL resulting in an overall survival rate of 80%, patients with advanced stage disease continue to have suboptimal outcomes, with relapse rates of 30%-40%. An additional 10%-15% of patients present with primary refractory disease. For patients who relapse after initial treatment, salvage chemotherapy followed by autologous stem cell transplant in those with chemotherapy-sensitive disease is the standard of care. Patients who relapse after second-line therapy have a median survival time in the range of 6-36 months, and the optimal management of these patients remains unclear. Unfortunately, there have been no new agents approved for relapsed HL treatment since the 1970s. Consequently, clinical decision making in this population is difficult. Recently however, several agents have emerged that have shown clinical promise in this poor-risk population. This review discusses the management of these patients and also discusses several newer agents showing clinical promise in the treatment of HL.

Current approaches to the treatment of non-Hodgkin's lymphoma.

Project description:Chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) has long been a standard treatment for lymphoma. Improvements to the efficacy of this regimen can be made by increasing the doses of doxorubicin and cyclophosphamide, as in the chemotherapeutic regimen of doxorubicin, cyclophosphamide, vindesine, bleomycin, and prednisone (ACVBP), and by reducing the standard dosing interval, as seen with the CHOP-14 regimen. Adding the immunotherapeutic agent rituximab (R) to either CHOP or ACVBP has been shown to improve outcomes significantly, such that six cycles of R-CHOP plus two cycles of ritux-imab are as effective as eight cycles of R-CHOP, and R-CHOP-21 appears to be at least as effective as the more dose-intense R-CHOP-14. In patients who have several adverse prognostic factors, R-ACVBP plus autologous stem-cell transplantation has been shown to produce good treatment outcomes. The use of positron emission tomography scanning before and early in treatment should allow prediction of long-term outcomes, and therefore the adaptation of treatment to individual prognosis and treatment needs. In patients with follicular lymphoma, rituximab has been shown to improve the efficacy of conventional chemotherapies. In addition, rituximab alone or yttrium-90-ibritumomab tiuxetan are effective maintenance therapies in this condition.

Relapsed Primary Central Nervous System Lymphoma: Current Advances.

Project description:Primary central nervous system lymphoma is an invasive malignant lymphoma confined to the central nervous system. Although patients undergoing first-line treatment can achieve complete response, most of them still relapse within two years. Relapsed lymphoma is derived from occult lymphoma cells, and B cell receptor pathway activation and immune escape are the key mechanisms for the pathogenesis of PCNSL. Most relapses are in the central nervous system, a small number of relapses are isolated systemic relapses, and clinical symptoms occur early and vary. Current treatments for relapse include high-dose methotrexate rechallenge and other regimens of chemotherapy, whole-brain radiation therapy, hematopoietic stem-cell transplantation, targeted therapy and immunotherapy, which have become promising treatments. The overall prognosis of relapsed PCNSL is very poor, although it is affected by many factors. This article summarizes the mechanisms, related factors, clinical features, follow-up, treatment and prognosis of relapsed primary central nervous system lymphoma.

Current status of autologous stem cell transplantation in relapsed and refractory Hodgkin's lymphoma.

Project description:Despite the relatively high long-term disease-free survival (DFS) rate for patients with Hodgkin lymphoma (HL) with modern combination chemotherapy or combined modality regimens, ?20% of patients die from progressive or relapsed disease. The standard treatment for relapsed and primary refractory HL is salvage chemotherapy followed by high-dose chemotherapy and autologous stem cell transplantation (ASCT), which has shown a 5-year progression-free survival rate of ?50%-60%. Recent developments in a number of diagnostic and therapeutic modalities have begun to improve these results. Functional imaging, refinement of clinical prognostic factors, and development of novel biomarkers have improved the predictive algorithms, allowing better patient selection and timing for ASCT. In addition, these algorithms have begun to identify a group of patients who are candidates for more aggressive treatment beyond standard ASCT. Novel salvage regimens may potentially improve the rate of complete remission prior to ASCT, and the use of maintenance therapy after ASCT has become a subject of current investigation. We present a summary of developments in each of these areas.

Immunotherapy for B-cell lymphoma: current status and prospective advances.

Project description:Therapy for non-Hodgkin's lymphoma has progressed significantly over the last decades. However, the majority of patients remain incurable, and novel therapies are needed. Because immunotherapy ideally offers target selectivity, an ever increasing number of immunotherapies, both passive and active, are undergoing development. The champion of passive immunotherapy to date is the anti-CD20 monoclonal antibody rituximab that revolutionized the standard of care for lymphoma. The great success of rituximab catalyzed the development of new passive immunotherapy strategies that are currently undergoing clinical evaluation. These include improvement of rituximab efficacy, newer generation anti-CD20 antibodies, drug-conjugated and radio labeled anti-CD20 antibodies, monoclonal antibodies targeting non-CD20 lymphoma antigens, and bispecific antibodies. Active immunotherapy aims at inducing long-lasting antitumor immunity, thereby limiting the likelihood of relapse. Current clinical studies of active immunotherapy for lymphoma consist largely of vaccination and immune checkpoint blockade. A variety of protein- and cell-based vaccines are being tested in ongoing clinical studies. Recently completed phase III clinical trials of an idiotype protein vaccine suggest that the vaccine may have clinical activity in a subset of patients. Efforts to enhance the efficacy of active immunotherapy are ongoing with an emphasis on optimization of antigen delivery and presentation of vaccines and modulation of the immune system toward counteracting immunosuppression, using antibodies against immune regulatory checkpoints. This article discusses results of the various immunotherapy approaches applied to date for B-cell lymphoma and the ongoing trials to improve their effect.

CXCL12 rs1801157 polymorphism in patients with breast cancer, Hodgkin's lymphoma, and non-Hodgkin's lymphoma.

Project description:Chemokines and their receptors regulate the trafficking of immune cells during their development, inflammation, and tissue repair. The single-nucleotide polymorphism (SNP) rs1801157 (previously known as CXCL12-A/ stromal cell-derived factor-1 (SDF1)-3'A) in CXCL12/SDF1 gene was assessed in breast cancer, Hodgkin's lymphoma (HL), and non-Hodgkin's lymphoma (NHL), since the chemokine CXCL12, previously known as SDF1, and its receptor CXCR4 regulate leukocyte trafficking and many essential biological processes, including tumor growth, angiogenesis, and metastasis of different types of tumors. Genotyping was performed by PCR-RFLP (polymerase chain reaction followed by restriction fragment length polymorphism) using a restriction enzyme HpaII cleavage. No significant difference was observed in genotype distribution between breast cancer patients (GG: 57.3%; GA: 39.8%; AA: 2.9%) and healthy female controls (GG: 62.9%; GA: 33%; AA: 4.1%) nor between HL patients (GG: 61.1%; GA:27.8%; AA: 11.1%) and healthy controls (GG: 65.6%; GA: 28.9%; AA: 5.5%), whereas a significant difference was observed in genotype distribution between NHL patients (GG: 51.4%; GA: 47.1%; AA: 1.5%) and healthy controls (GG: 65.6%; GA: 28.9%; AA: 5.5%). Further studies will be necessary to elucidate the cancer chemokine network. However, this study suggests that CXCL12 rs1801157 polymorphism may have important implications in the pathogenesis of NHL.
