Peripheral T-Cell Lymphoma: What’s the Role for Transplant?

The number of recently approved agents and those under investigation is promising. However, there are currently no recommendations regarding the optimal timing for use of these agents, a reflection of the lack of data in this area and the need for prospective studies.

Conclusions Epidemiological studies have repeatedly helped identify definitive triggers for several diseases. As highlighted in this perspective report, previous studies strongly argue for the interplay between intrinsic factors and putative preventable extrinsic triggers/promoters for CTCL. Given the evidence of geographical regional clustering of CTCL patients, CTCL occurrence in unrelated family members and recent evidence implicating S. aureus in the pathogenesis/progression of CTCL, more research is needed to decipher the precise mechanism by which specific environmental exposures may be driving the pathogenesis of t...

Conclusions The major challenges in the development of adoptive cell therapy for T cell tumors, as mentioned above, remain fratricide, T cell aplasia and the potential for leukemic transduction or poor T cell function if used in the autologous setting. Approaches to overcome fratricide include the genetic modification and deletion of the T cell antigen in the case of long-term CAR-T cell persistence or regulated CAR-T expression. To ensure restoration of T cell immunity, transient CAR expression can be achieved incorporation of a CAR suicide gene, transient CAR expression using mRNA electroporation, or short-lived NK cell...

Discussion In this section, we discuss the mechanisms responsible for lymphomagenesis in the various inborn errors of immunity and provide an overview of the treatment. Defects in Immune Responses That Predispose to Lymphomagenesis in PIDDs The complex immune mechanisms and their interplay that predisposes to neoplastic transformation of B or T cells and development of lymphomas in PIDD patients has not been fully elucidated. However, it is expected that the etiology in most cases is multifactorial and related to a dynamic regulation of immune response and environmental triggers (Figure 3). An underlying intrinsic susce...

Authors: Ling YL, Huang X, Mitri G, Lovelace B, Pham, Knobler R, Li X, Gao X Abstract INTRODUCTION: The National Comprehensive Cancer Network and the European Organization for Research and Treatment of Cancer recommend extracorporeal photopheresis (ECP) as systemic therapy for cutaneous T-cell lymphoma (CTCL). OBJECTIVE: To investigate real-world use of ECP in CTCL patients in the US. METHODS: Data from the Truven MarketScan® database (2010-2015) were used to create a cohort of CTCL patients receiving systemic treatment. Multivariable regressions were performed to compare health care resource utilizatio...

Background:Somatic driver mutations in hematopoietic cells may lead to clonal hematopoiesis of indeterminate potential (CHIP). In patients with lymphoma CHIP has been associated with increased risk of therapy-related myeloid neoplasms (tMN) and inferior survival after autologous stem cell transplantation as demonstrated in a large single center study and in a case-control study (Gibson CJ et al., JCO 2017 and Berger G et al., Blood 2018). Here, we investigated the clinical impact of clonal hematopoiesis in a nation-wide population-based cohort of Danish lymphoma patients undergoing autologous transplant with prospective da...

Conclusions: Patients with TCL who need to start chemotherapy within 15 days of diagnosis have a lower likelihood of undergoing subsequent SCT. This association is not fully explained by early mortality, and may reflect a more aggressive biology, including worse response to standard chemotherapy-a hypothesis supported by the fact that achievement of SCT nullifies the poor prognostic value of short DTI. Short DTI is thus a novel risk factor in TCL that identifies a high-risk population well suited to experimental treatment strategies, and clinical researchers should strive to enroll these patients. Outcomes from clinical tr...

Conclusion: aTac- BEAM appears to be safe as an ASCT conditioning regimen for PTCL with no increased toxicity as compared to the historical toxicities seen with BEAM alone in this patient population (D'Amore 2012 J of Clin Onc). The dose level 0.6mCi/kg will likely be the recommended phase II dose. An expanded phase is planned to evaluate the efficacy of this regimen followed by a randomized trial of BEAM alone plus a combination of aTac- BEAM.Figure 1.DisclosuresHerrera: Seattle Genetics: Research Funding; Bristol-Myers Squibb: Consultancy, Research Funding; Genentech: Consultancy, Research Funding; Immune Design: Researc...

Objective18F-fluorodeoxyglucose (FDG)-positron emission tomography (PET) is used routinely for response assessment and treatment decision making in Hodgkin lymphoma and B cell non-Hodgkin lymphoma. The predictive value of PET/CT in patients with peripheral T-cell lymphomas (PTCL) is not well defined. We performed a retrospective single institution analysis to determine the utility of pre-transplant PET/CT to predict outcomes following autologous stem cell transplant (ASCT) for PTCL.Materials and MethodsPET/CT patient populationWe screened the Dana-Farber Cancer Institute database for patients undergoing ASCT between 2005 a...

BackgroundHigh dose chemotherapy and autologous stem cell transplant (ASCT) results in cure for up to 50% of patients with Hodgkin (HL) and aggressive non-Hodgkin lymphoma (NHL) that relapse after initial treatment with chemo-immunotherapy. Despite improvements in supportive care and patient selection, death after ASCT remains a concern due to progressive disease, infection, and other treatment- and non-treatment-related causes. We evaluated causes and predictors of death in patients undergoing ASCT for HL and NHL.MethodsWe conducted a single-institution, retrospective study of all patients with HL and NHL including diffus...
