Inotuzumab ozogamicin has achieved a markedly long antitumor response in patients with refractory or relapsed indolent B-cell non-Hodgkin lymphoma (NHL) in an ongoing phase II study. Interim findings were reported by lead investigator Kenneth Luu, PhD, associate director of Pfizer global R&D.

A combination of TL32711, an investigational second mitochondrial-derived activator of caspases (Smac), and tumor necrosis factor-related apoptosis inducing ligand at low concentrations produced marked apoptosis in germinal center lines, with minimal to no effect for each agent alone.

Preliminary findings of a phase I/II randomized clinical trial indicate that SGI-110, a novel DNA methylation inhibitor, is safe, well tolerated and efficacious in patients with acute myelogenous leukemia.

In this article, we review the current knowledge on the biological findings, clinical features, and therapeutic approaches for splenic marginal zone lymphoma.

Four publications on cancer treatment during pregnancy were published last week in the journal Lancet, serving as new treatment guidelines for chemotherapy and surgery in pregnant patients with solid tumors and hematologic malignancies.

Splenic lymphomas are a diverse group of lymphoid malignancies that have clinical behavior ranging from indolent to aggressive and that have both B-cell and T-cell histologies.

The article by Thieblemont and colleagues very nicely summarizes the key pathogenetic and diagnostic features and present treatment of splenic marginal zone lymphoma (SMZL).

Until we fully engage in understanding the biologic mechanisms that separate NMZL from other indolent NHLs, however, we will continue to deliver “impersonalized medicine” that does not exploit the unique properties of the former.

Typically, when one authors a commentary piece, a good template to follow is to start with some background material, review the major findings of the paper in question, and then focus on areas of controversy and unanswered questions.

The aim of this review is twofold: to summarize descriptions of the clinical presentation provided in published series in order to help clinicians recognize and treat patients, and to discuss diagnostic difficulties faced by hematopathologists when dealing with these lesions and others in the differential diagnosis that must be distinguished from one another.

The results of the 2-year follow-up of the dasatinib DASISION phase III trial show the continued superiority of the drug compared to imatinib. The results provide further support for treatment of first-line chronic phase chronic myeloid leukemia patients that harbor the Philadelphia chromosome.

Results of the phase III SWOG S0016 trial comparing 2 chemotherapy regimens for follicular lymphoma (FL), presented this week at ASH, show no statistically significant differences in either progression-free survival (PFS) or overall survival. Both regimens produced “excellent” results, according to the presenter.

The phase III randomized RESORT (ECOG Protocol E4402) trial asked whether a maintenance schedule of rituximab every 3 months would lead to a superior disease control outcome compared to retreatment upon progression. The answer, presented this week at ASH, is no.

The phase III trial comparing the use of gemtuzumab ozogamicin combined with chemotherapy to chemotherapy alone in newly diagnosed acute myeloid leukemia (AML) patients provides evidence that the combination treatment may be promising in this patient population.

Obinutuzumab (GA101) achieved higher response rates than rituximab in the first head-to-head trial of the two biologic agents in patients with relapsed non-Hodgkin lymphoma.

Encouraging findings were reported from multiple studies of ibritumomab tiuxetan (Zevalin), a CD20-directed radiotherapeutic antibody, in diverse patient groups with follicular lymphoma.

Andrew Evens, DO, MSc, deputy director for clinical and translational research and medical director of the Clinical Research Office at the UMass Memorial Health Care Cancer Center of Excellence, talks about his research on lymphoma during pregnancy.

CancerNetwork highlights four sessions--on anaplastic large cell lymphoma, lymphoma in pregnancy, follicular lymphoma, splenic marginal zone lymphoma--you won’t want to miss from this year’s ASH.

The US Food and Drug Administration has approved asparaginase Erwinia chrysanthemi for the treatment of patients with acute lymphoblastic leukemia, who have developed hypersensitivity to E. coli derived asparaginase and pegaspargase chemotherapy.

A survey of more than 500 long-term survivors of non-Hodgkin’s lymphoma (NHL) has revealed that more than one-third experience persistent or worsening symptoms of post-traumatic stress disorder (PTSD), with nearly 4 of 10 cancer survivors stating they still experience symptoms of PTSD more than a decade after their cancer diagnosis.

Marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) lymphoma is an indolent B-cell non-Hodgkin lymphoma arising from the lymphoid tissue at extranodal sites.

After more than two decades of successful laboratory and clinical research, the "new" entity of mucosa-associated lymphoid tissue (MALT) lymphoma is reaching a noble maturity.

Normal B lymphocytes can follow either of two functionally distinct pathways of development. The first is a classical germinal center T-dependent pathway in which diversification and maturation generate a delayed but almost unlimited high-affinity response to antigens.

A case report is followed by a review of the diagnosis and treatment of other cutaneous paraneoplastic syndromes that are associated with hematologic malignancies.

A recent case report in the New England Journal of Medicine highlights the promising potentials of adoptive T-cell immunotherapy by redirecting them, through chimeric antigen receptors, as a novel and effective therapeutic modality for cancer.

The U.S. Food and Drug Administration (FDA) announced last week the approval of brentuximab vedotin, a CD30-directed antibody drug-conjugate, for the treatment of refractory Hodgkin lymphoma and systemic anaplastic large-cell lymphoma.

Equine ATG has been used for the treatment of severe aplastic anemia since the 1980s. Rabbit ATG is used in many parts of the world including South America, Japan, and European countries. The results of a randomized study of equine versus rabbit ATG showed that rabbit ATG was inferior to equine ATG.

Researchers at the University of Pennsylvania have reported on the results of a trial in which a patient with chronic lymphocytic leukemia (CLL) experienced a complete remission after immunotherapy with tumor-reactive modified T cells.

Results of a Phase I study of the novel Poly(ADP-ribose) polymerase (PARP) inhibitor veliparib (ABT-888) in solid tumors and lymphoma have just been published in Cancer Research (doi:10.1158/0008-5472.CAN-11-1227).

Researchers at the University of Chicago and colleagues have identified two variants on chromosome 6q21 that are associated with second malignant neoplasms (SMNs) in survivors of pediatric Hodgkin’s lymphoma. The SMNs are linked to radiation therapy used to treat the pediatric cancer.
