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.
Scientists at the University of British Columbia have found that histone-modifying genes are often mutated in non-Hodgkin’s lymphoma (NHL).
There has been dramatic progress in the management of acute promyelocytic leukemia during the past three decades. Important insights into the pathogenesis of the disease have come to light and effective treatment has been developed.
In their scholarly article, Dr. Park and Dr. Tallman review the important clinical trials for treating patients with APL reported over the last two decades and argue the case for further reduction and perhaps elimination of conventional cytotoxic chemotherapy in the frontline treatment of this disease.[1]
In this excellent review of acute promyelocytic leukemia (APL) treatment, the authors highlight opportunities offered by incorporating arsenic trioxide (ATO) into the therapeutic armamentarium.
The current dogma considers cytomegalovirus (CMV) seropositivity being associated with inferior outcomes post hematopoietic stem cell transplant (HSCT). However, there has been a notion of “virus-versus-leukemia” effect since the 1980s; and recently, there have been some interesting reports which may turn this to a hot topic.
A rarely noted aspect of the era of novel agents and explosive new knowledge in the clonal plasma cell diseases is how short the half-life of relevant information has become, and how this churning has challenged clinical thinking.
In this issue of ONCOLOGY, Dr. Robert Kyle and colleagues provide their clinical and epidemiological perspective on monoclonal gammopathy of undetermined significance (MGUS) and smoldering myeloma (SMM)-a perspective that is based on more than three decades of experience.
In his plenary address as outgoing president of ASCO, Dr. George Sledge proposed that we are on the brink of a new era in cancer therapy – an era of genome-based treatment. He stressed that this new “genomic era” holds great promise for patients, citing as evidence a recent paper in JAMA that described a case in which the results of deep sequencing of a patient’s leukemic cells led to successful individualized therapy.
In this video interview, Joseph Connors gives an overview of the results presented here at ASCO of the phase II trial of brentuximab vedotin in patients with relapsed or refractory Hodgkin lymphoma, and discusses the most intriguing work currently being done with novel agents used to treat relapsed or refractory Hodgkin lymphoma.
A growing understanding of the biology behind myelodysplastic syndromes (MDS) is leading the way to improved treatment options, according to two presentations at the American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago.
Despite dramatic improvements in survival for children and young adults with acute lymphoblastic leukemia (ALL), treatment failure in the central nervous system remains a constant foe.
In an article published online on May 9, 2011 in the Journal of Clinical Oncology, a large-scale prospective study found that acetaminophen use was associated with an almost two-fold increase risk of hematological malignancies other than chronic lymphocytic leukemia/small lymphocytic lymphoma.
Myelodysplastic syndromes, also referred to collectively as MDS, have significant biological and clinical heterogeneity, a highly variable natural history, and a complex pathobiology that is not clearly understood.
The myelodysplastic syndromes (MDS) are a heterogeneous spectrum of clonal hematopoietic diseases characterized by bone marrow hypercellularity, dysplasia of cellular elements, and consequent inadequate hematopoiesis, with resultant peripheral blood cytopenias.
The review by Dr. Akhtari outlines the diagnosis, prognosis, and treatment options for patients with myelodysplastic syndromes (MDS), and touches on the current challenges in treating patients suffering from MDS.
This review will cover the key elements of modern acute lymphoblastic leukemia treatment regimens, focusing primarily on front-line treatment and concluding with a brief discussion of the management of relapsed disease.
We have witnessed remarkable gains in the biological understanding and treatment of acute lymphoblastic leukemia (ALL) over the past decade.
About 35 years ago, I encountered several children and adolescents with acute lymphoblastic leukemia or widespread non-Hodgkin lymphoma who presented with or who developed, upon initiation of therapy, severe renal and metabolic derangements.
The FDA has approved Rituxan for first-line maintenance treatment of patients with advanced follicular lymphoma who responded to initial treatment with Rituxan plus chemotherapy.
The accurate and in-depth documentation of learning gaps is a fundamental aspect of developing continuing education activities. To obtain a better understanding of community-based medical oncology practice patterns, 43 oncologists within the United States were recruited to complete a traditional clinical case–based questionnaire and to contribute specific anonymous demographic and treatment information derived from their actual patients. This information was used to create a cross-sectional case database on two types of cancer in which major clinical advances have been reported in recent years - multiple myeloma and follicular lymphoma. These diseases also are similar in that most patients experience clinically meaningful benefits from systemic treatment but are unlikely to be cured by therapy. As further described in this and the subsequent two articles, this case-based series documents that (a) clinical research advances are being quickly implemented in daily patient care and that (b) although therapeutic strategies vary based on patient age, the short-term outcomes in terms of response to and tolerance of treatment are similar in younger and older patients.
A number of recent treatment advances in the management of follicular lymphoma (FL), including the introduction of the anti-CD20 monoclonal antibody rituximab, have effectively shifted the primary therapeutic goal away from palliation and avoidance of toxicity toward the more proactive objective of extending survival. This paper reviews recent practice patterns in the broad context of the published findings from major phase III randomized trials; it documents potential gaps between trial results and actual practice, and the implications of these for continuing education of oncologists. Forty-three US-based community oncologists participated in a cross-sectional case survey during which 40 documented their management of 186 patients with newly diagnosed FL and 133 patients with relapsed FL, all of whom were treated after January 1, 2008. The findings from this initiative indicate that the majority of these patients did not have any major symptoms at presentation. Additionally, tolerance of and response to treatment, regardless of the regimen employed, were similar across the different age groups studied (<65, 65-74, ≥75 years). Therapies selected by the physicians surveyed in both the up-front and the relapsed settings broadly corresponded to the evidence-based published literature and were supported by treatment guidelines. In addition, a change in the proportional use of bendamustine/rituximab (BR) in the up-front treatment of FL from 2008 to 2010 was observed, suggesting that community oncologists are rapidly incorporating pivotal clinical trial results when deciding on individual patient management strategies.
The median reductions in Bcr-Abl transcripts at one year were greater with dasatinib (Sprycel) than with imatinib (Gleevec), according to the results of an intergroup phase II trial. A better molecular response should eventually correlate with better outcomes, making dasatinib a serious contender for upfront therapy in CML.
Study leader Kirit M. Ardeshna, MD, tells Oncology NEWS International that he predicts this pretreatment approach will become the standard of care and will prove attractive to patients because chemotherapy can be deferred for even longer than it can now. But participants at an ASH 2010 plenary session questioned aspects of the trial design.
The intensified regimen of BEACOPP plus standard therapy ABVD plus radiotherapy bested four cycles of ABVD alone, leading to a significant improvement in tumor control. Final results from the German Hodgkin Study Group trial saw a 7% improvement in terms of freedom from treatment failure between the standard and new treatment arms.
