2018 American Society of Clinical Oncology (ASCO) Annual Meeting

The American Society of Clinical Oncology (ASCO) is the world’s leading organization for physicians and oncology professionals who care for people with cancer. Each year, ASCO’s Annual Meeting brings together over 30,000 oncology professionals from around the world to discuss state-of-the-art treatment modalities, new therapies and ongoing controversies in the field.

Our Lymphoma Program is proud to have been part of several research studies presented at this year’s meeting, contributing to new discoveries across a range of lymphoma subtypes. Here are the latest updates from our team:

T-Cell Lymphoma

An unmet treatment need exists for peripheral T-cell lymphoma patients, especially those with relapsed/refractory disease. Dr. Jia Ruan was part of a research team testing immunotherapy agent pembrolizumab within this patient population.

Follicular Lymphoma

Dr. Peter Martin was involved in a clinical trial investigation of acalabrutinib in treatment of follicular lymphoma, which yielded promising response rates.

Data supporting vitamin D supplementation in indolent lymphoma patients treated with rituximab were presented at this year’s meeting. Dr. John Leonard is Weill Cornell Medicine and NewYork-Presbyterian’s principal investigator evaluating the vitamin’s effects in an ongoing phase III trial. Trial information here.

Diffuse Large B-Cell Lymphoma (DLBCL)

Dr. Jia Ruan was involved in the clinical trial assessment of single-agent acalabrutinib in relapsed/refractory DLBCL patients.

Waldenstrom’s Macroglobulinemia

Dr. Richard Furman was senior author on a study demonstrating acalabrutinib as an effective and well-tolerated therapy for people with Waldenstrom’s macroglobulinemia.

Chronic Lymphocytic Leukemia (CLL)

Dr. John Allan, along with Dr. Richard Furman, collaborated with research colleagues to investigate the demographic impact on incidence and treatment outcomes in people with chronic lymphocytic leukemia (CLL).

Dr. John Allan is Weill Cornell Medicine and NewYork-Presbyterian’s principal investigator for a phase II clinical trial of ibrutinib and venetoclax – two non-chemotherapeutic agents – in people with previously untreated chronic lymphocytic leukemia (CLL). Trial information here.

Non-Hodgkin Lymphoma

People with human immunodeficiency virus (HIV) are at increased risk for developing aggressive non-Hodgkin lymphomas frequently associated with two herpes viruses: Epstein-Barr virus (EBV) and Kaposi’s sarcoma-associated herpes virus (KSHV). Weill Cornell Medicine pathologist Ethel Cesarman, MD, PhD, contributed to a phase II trial conducted through the AIDS Malignancy Consortium (AMC) to test HDAC inhibitor vorinostat’s effects on HIV-related non-Hodgkin lymphoma.

Dr. Peter Martin, the Principal Investigator for the Lymphoma Epidemiology of Outcomes (LEO) consortium at Weill Cornell Medicine and NewYork-Presbyterian Hospital, aided in a study of vulnerability to undesirable outcomes in people with newly diagnosed non-Hodgkin lymphoma. Vulnerable status was measured overall, and by age, gender and clinical features.

As always, we are proud of our team’s active commitment to advancing the overall understanding of lymphoma and improving clinical outcomes and quality of life for all those affected by the disease.

Scientists Identify Four New Genetic Subtypes of Diffuse Large B-Cell Lymphoma

Diffuse large B-cell lymphoma (DLBCL), the most common form of non-Hodgkin lymphoma, has been categorized based on the cancer cell of origin as either activated B-cell (ABC) DLBCL or germinal center B-cell (GCB) DLBCL. Each subtype is associated with a certain degree of tumor vulnerability and a corresponding response to therapy.

The more that clinicians know about how a patient’s disease develops, the better equipped they are to devise an informed and precise treatment plan. Yet, between 10-20 percent of DLBCL cases are unclassified, providing little guidance for strategic intervention.

To shed light on the unclassified disease subtype and further define the composition of the ABC and GCB subtypes, the Weill Cornell Medicine and NewYork-Presbyterian Hospital Lymphoma Program’s Dr. John P. Leonard took part in an international research initiative led by the National Cancer Institute at the National Institutes of Health, with findings recently published in the New England Journal of Medicine.

Whereas prior studies of genetic subtyping investigated individual mutations, this research was among the first to examine how mutations in multiple genes may relate to disease pathogenesis and therapeutic response.

Researchers used next-generation sequencing technology to analyze nearly 600 DLBCL patient biopsy samples, contributed in part through the Lymphoma Program’s efforts in collaboration with the Alliance for Clinical Trials in Oncology. Based on the co-occurrence of genetic alterations that they observed, the team discovered four new genetic subtypes of DLBCL – MCD, BN2, N1 and EZB – enhancing science’s understanding of the genetic framework of this aggressive cancer.

“These findings will take us one step closer to potentially employing targeted agents as part of treatment for specific DLBCL subtypes,” says Dr. Leonard. “If we can specifically identify these lymphoma types and incorporate new agents that target relevant pathways, we will advance rational clinical trials with the aim to improve outcomes for patients based on the biology of their disease.”

Dr. John Leonard Awarded for Outstanding Patient Care

The Lymphoma Program’s Dr. John Leonard was granted the prestigious 2017 Miriam G. Wallach Award for Excellence in Humanistic Medical Care at Weill Cornell Medicine and NewYork-Presbyterian Hospital’s Physician of the Year event, as presented by the Department of Nursing. The award honors a physician who exemplifies altruistic and humanistic qualities and displays exceptional dedication to providing outstanding, compassionate patient-centered care.

Dr. Cam Patterson, Senior Vice President and Chief Operating Officer for NewYork-Presbyterian Hospital/Weill Cornell Medicine, helped to introduce Dr. Leonard and present the award. He noted that Dr. Leonard is widely acknowledged by his colleagues both locally and nationally for his stature in the field of lymphoma research and care, especially known for his astuteness in taking on challenging cases, such as treating pregnant women with lymphoma. He is also regarded as a great partner to his nursing colleagues.

“Receiving an award that is reflective of the feelings of the nursing staff is about as good as it gets,” said Dr. Leonard.

In his acceptance remarks, Dr. Leonard described interactions with his patients staying in the hospital the previous evening. Throughout the course of his visits, conversation topics spanned serious, difficult discussions, as well as some of a more lighthearted nature, including doubles tennis and the New York Yankees.

Dr. Leonard explained that making his rounds took only a few minutes, but it was the most fun part of his day, and it made a difference to his patients. He noted that small interactions, such as sitting down to talk and certain intricacies in the way that we connect with one another, have the potential to make a huge difference in our relationships.

“These things that you do on a daily basis and don’t even think of affect patients, colleagues and trainees,” said Dr. Leonard. “If we understand that and deliberately carry it through [to practice], we can make an even greater difference for our patients.”
