Mantle Cell Lymphoma

Antibody–drug conjugate therapies are making a larger impact on the treatment paradigm for patients with lymphomas, especially following promising data for brentuximab vedotin and inotuzumab ozogamicin.

Pontchartrain Cancer Center was founded in 2005 to serve an area of Louisiana that lacked the necessary resources for cancer care. This community cancer center, with 2 locations in Southeast Louisiana, accommodates any patient to walk through its doors, filling a major unmet need for the community in this rural area.

The partial clinical hold previously placed on trials examining tazemetostat in patients with various solid tumors and hematologic malignancies has been lifted by the FDA and enrollment has been reopened.

Mantle cell lymphoma remains an incurable disease, but according to Michael Wang, MD, it is becoming one of the most dynamic fields in oncology. In a presentation during the 2018 SOHO Annual Meeting, Wang recapped some of the biggest advancements in relapsed/refractory MCL, as well as the promise for novel therapies in this setting.

In a presentation during the 2018 SOHO Annual Meeting, Simon Rule, MD, PhD, discusses the treatment of newly-diagnosed patients with MCL, emphasizing the benefits of the watch-and-wait approach.

Bijal D. Shah, MD,  discusses the challenge of treating this highly heterogeneous disease, how to choose the optimal treatment regimen, and the ongoing role of BTK inhibitors.

In an interview with&nbsp;<em>Targeted Oncology</em>, Simon Rule, MD, PhD, professor of Hematology at Plymouth University Medical School, United Kingdom, discusses the current treatment paradigm for MCL, as well as the potential use of BTK inhibitors for the treatment of this patient population.

Axicabtagene ciloleucel (axi-cel; Yescarta) has been approved by the European Commission as a treatment for&nbsp;adult patients with relapsed/refractory diffuse large B-cell lymphoma or primary mediastinal large B-cell lymphoma, following at least 2 lines of systemic therapy.&nbsp;

Tisagenlecleucel has gained approval from the European Commission as a treatment for adult&nbsp;patients with diffuse large B-cell lymphoma that is relapsed or refractory after 2 or more lines of systemic therapy, or patients up to 25 years of age with B-cell acute lymphoblastic leukemia that is refractory, in relapse posttransplant, or in second or later relapse.

Mutations of <em>TP53</em> and <em>WHSC1 </em>predicted poorer overall survival in patients with mantle cell lymphoma, according to results from next-generation whole-exome sequencing of 16 Chinese patients.&nbsp;The presence of these mutations may provide physicians with an important biomarker in this patient population.

Targeting EZH2, the catalytic subunit of the multiprotein PRC2, may represent an attractive therapeutic objective in malignant lymphoma, Vincent Ribrag, MD, told his audience at the American&nbsp;Association for Cancer Research&rsquo;s inaugural Advances in Malignant Lymphoma meeting.

Brad Kahl, MD,&nbsp;discusses the exciting new advancements on the horizon for the treatment of patients with MCL.

Andre Goy, MD, shares insight on the new array of treatment options for mantle cell lymphoma and how to properly implement them.

Mogamulizumab-kpkc&nbsp;(Poteligeo) has been approved by the FDA as a treatment for patients with cutaneous T-cell lymphoma who have received at least 1 prior systemic therapy.

Patients with relapsed/refractory mantle cell lymphoma (MCL) who experienced progression of disease within 2 years following an upfront chemoimmunotherapy regimen containing high-dose cytarabine were more likely to have worse outcomes than patients who progressed later, according to the results of a retrospective analysis presented at the 2018 European Hematology Association Congress. Alternatively, patients who experienced POD later had an unexpectedly long life expectancy.

Brad S. Kahl, MD, professor in the department of medicine at Washington School of Medicine at Siteman Cancer Center, discusses the use of ibrutinib (Imbruvica) in older patients with mantle cell lymphoma. This agent is currently being investigated in the frontline setting for patients not eligible for stem cell transplant.

The addition of bortezomib to rituximab as a maintenance therapy following consolidative autologous hematopoietic stem cell transplantation may improve disease-free survival and overall survival in patients with mantle cell lymphoma, results of a small phase II study suggest.

The combination of ibrutinib (Imbruvica) and rituximab (Rituxan) produced durable remissions in patients with relapsed/refractory mantle cell lymphoma, according to 4-year follow-up results from a single-arm phase II clinical trial.

Maintenance rituximab improved progression-free survival and overall survival following induction chemoimmunotherapy for&nbsp;patients with mantle cell lymphoma, according to results of a recent meta-analysis.<br /> &nbsp;

Jacqueline D. Barrientos, MD, MS, CLL Research and Treatment Program at Northwell Health Systems, advises community oncologists on how to treat patients with mantle cell lymphoma. She emphasizes the importance of seeking a second opinion for patients that are not responding to treatment.&nbsp;

Michael Wang, MD, discusses what he hopes to find in the ZUMA-2 trial and his belief that MCL can be cured in his lifetime.

An overall response rate of 60% was induced with venetoclax (Venclexta) monotherapy in&nbsp;patients with poor-risk relapsed/refractory mantle cell lymphoma who were previously treated with&nbsp;a BTK inhibitor,&nbsp;according to results presented at the 2018 European Hematology Association Congress.&nbsp;Of the responding patients, 20% had a complete response.

In patients with untreated advanced-stage classical Hodgkin lymphoma, PET can be safely used to&nbsp;guide treatment after 2 cycles of&nbsp;upfront de-escalated BEACOPP, according to the final analysis of the&nbsp;phase III LYSA study presented at the 2018 European Hematology Association Congress.

The 16-gene Leukemic-MCL16 (L-MCL16) Assay reliably distinguished between classic and indolent mantle cell lymphoma subtypes in patients with leukemic presentation, according to results published in <em>Blood</em>. Combined with genomic complexity, the assay was prognostic for overall survival.

The biggest clinical unmet need in the treatment of patients with mantle cell lymphoma is overcoming resistance to BTK inhibitors, as patients who progress on treatment with ibrutinib&nbsp;(Imbruvica) and acalabrutinib (Calquence) are often incurable, according to Michael Wang, MD. Investigators are now challenged to find a new avenue of treatment.
