New Findings May Play Role in Development of Future DLBCL Treatments

Researchers from Weill Cornell Medicine led by Dr. Olivier Elemento, recently published results announcing the discovery of thousands of new genes from human samples of lymphoma. Known as IncRNAs these genes produce long non-coding RNAs and are involved in gene regulation. The IncRNAs appear to control whether other genes make proteins. The discovery of these genes could underline the processes of gene regulation that drives lymphomas, while in the future leading to possible targets for new  diffuse large B-cell lymphoma therapies.

“These genes produce long non-coding RNAs, known as lncRNAs. Unlike RNA that produces proteins that enable the body to do its work, the lncRNA appear to switch on — or off — other genes that make proteins, researchers say. They counted 2,632 different forms of these unusual RNA molecules. They also found a substantial number of the same or similar lncRNAs in canine lymphoma.”

The study’s senior author, Dr. Olivier Elemento commented,

“While we don’t know precisely what these molecules are doing, the fact that the majority — about two-thirds — of the long non-coding RNAs we found are expressed exclusively in lymphoma, and that many are found in both human and dog lymphoma, tells us that they are likely playing fundamental roles in this cancer…”

Findings like these exemplify the bench to bedside approach in the Lymphoma Program at Weill Cornell Medicine. Look to this space for future updates on this topic and other advances in the treatment of lymphoma.

Researchers Develop New Method to Test Lymphoma Treatments

Researchers from Cornell Ithaca and Weill Cornell Medicine recently published a new study describing how organoids offer a realistic model to test new lymphoma treatments. A organoid is a tissue culture that mimics the environment where different lymphomas are found. The use of organoids could offer insights as to why some lymphoma treatments are more effective than others. As Dr. Ari Melnick explained:

“This is a game-changing technology for the field of lymphoma,” Melnick said. “These organoids allow us to better understand the complex architecture of lymphomas and how that informs the way we treat the disease – what drugs we should use and for whom, and how they interact with each other. This is a fundamental advance; no one in the world has the technology to treat patients in this way.” 

Research into lymphoma organoids are part of the P.A.Th. (Progressive Assessment of Therapeutics) program, an inter-campus collaboration between Cornell Ithaca and Weill Cornell Medicine that seeks to better translate the treatment of lymphoma patients.

Q & A with Dr. Peter Martin on High Dose Cytarabine for Mantle Cell Lymphoma Patients

In a recent interview with Clinical Advances in Hematology & Oncology, Dr. Peter Martin answered questions about the use of high dose cytarabine for patients with mantle cell lymphoma.

H&O How much does high-dose cytarabine improve patient outcome?

PM I do not think that has been very well defined. Not all of these data have sufficient long-term follow-up to comment on overall survival outcomes. Historically, patients were given R-CHOP followed by ASCT. The MCL-2 trial, published by Geisler and colleagues, added high-dose cytarabine and rituximab, and found that the outcomes were far superior in terms of progression-free survival and overall survival. However, these outcomes may not be solely due to high-dose cytarabine. Other explanations include the addition of rituximab, other changes in supportive care, and better pathology. Cytarabine may be part of that story, but it may not be the whole story.

The better trial to evaluate the potential role of cytarabine is the MCL Younger Trial that I mentioned earlier, which is a phase 3 trial published by Hermine and colleagues that compared 6 cycles of R-CHOP vs the R-CHOP/R-DHAP regimen. In this trial, the addition of R-DHAP seemed to reduce the risk of disease progression by approximately 30%. The study also found that the R-CHOP/R-DHAP regimen prepared people for ASCT better than R-CHOP alone.
