Immune and Molecular Therapy of Gastrointestinal Stromal Tumor/ DeMatteo Lab 2023
Ronald P. DeMatteo MD
Background: GIST is the most common human sarcoma, and approximately 85% of these tumors are attributable to a mutation in either KIT or PDGFRA genes. Imatinib mesylate is a tyrosine kinase inhibitor (TKI) that targets both of these genes and is effective in nearly 80% of patients with GIST. The advent of tyrosine kinase inhibitors has increased the median survival from 1 year to over 5 years. Despite this success, imatinib and the other tyrosine kinase inhibitors are not curative even in patients who respond, and many GISTs develop resistance to these drugs, necessitating further therapeutic approaches. Our lab has recently focused on discovering alternative approaches that may increase the efficacy of these tyrosine kinase inhibitors with combination therapy.
Current Focus & Future Directions: We have been using our immunocompetent, genetically engineered Kit V558Δ/+ mouse model which develops a cecal GIST with similar histology, Kit signaling, response to tyrosine kinase inhibitors, and immune response as seen in human GIST. We recently published work on Kit ligand, the natural ligand for the Kit receptor and showed that tumor cells as well as endothelia and smooth muscle cells produce Kit ligand in our mouse model, even after imatinib therapy.
Kit ligand remains an important therapeutic target. In addition, we also recently published details of an in vivo model that was developed to study a particular PDGFRA mutation and the mechanism of tumor persistence following treatment with avapritinib, a drug used after patients develop resistance to imatinib. We found that resistance to avapritinib can be caused by upregulation of myosin light-chain kinase (MYLK) inhibition and suggest that concomitant MYLK inhibition may enable the use of a lower dose of avapritinib to avoid cognitive side effects.
In addition to the above mechanisms, we are also studying various immune targets to block or activate in conjunction with imatinib to enhance imatinib’s anti-tumoral effect. These targets include ICOS, CD40, and VISTA. We are also utilizing recently acquired scRNAseq data of human GIST samples in order to categorize different immune cell populations and their gene expression to correlate to treatment response.
Summary: Our lab continues to search for new therapies to enhance the activity of tyrosine kinase inhibition in the treatment of GIST. We will be working to better understand TAMs in order to recruit and activate these immune cells to enhance the immune response to GIST. We will then be using combination therapy focusing on CD40 with the goal of activating the immune system to work in tandem with imatinib. We are so grateful for your continued support as we work toward these goals of combating human GIST.

In Memory of My Aunt, Stephanie Kalenda
Stephanie (Teta) Kalenda had GIST cancer. Like so many patients, she fought a valiant fight against this disease and yet lost her life. Her niece, Jamela, decided to start a small fundraiser beginning on July 12, GIST Awareness Day in memory of her Teta, who would have been 64 years old. She was looking for 64 donations. While she didn't make the goal, she still raised over $1700. for GIST Cancer Research. This young woman is making a difference in the fight for a cure of GIST Cancer. She made a stand and took action so that one day, there will be cure of this terrible disease.
One behalf of all of us at GCRF, thank you Jamela! Your Teta will always be remembered and loved.

Tania’s Story and the Formation of the GIST Cancer Research Fund
“I started with just a little website,” Tania says. “I went on local radio. I went to our local paper and told them my story.” In 2001, she held her first walkathon and raised $23,000. In 2018, the foundation has raised more than $10 million dollars and every penny has gone to GIST Cancer Research.
United States Senator, Charles “Chuck” Schumer graciously acknowledged the GIST Cancer Research Fund with a proclamation for the importance of the numerous contributions that the GIST Cancer Research Fund and the Walk For A Cure has made to find a cure for GIST Cancer.
A Message of Hope
GCRF received a special letter from the spouse of a GIST Cancer patient giving us all hope.
GIST - A Rare Orphan Cancer
Gastrointestinal Stromal Tumor or GIST is a rare, orphan cancer which starts in a type of tissue called the stromal or the body’s connective tissue (fat, muscle, blood vessels, deep skin tissues, nerves, bones or cartilage). GIST is a silent cancer often spreading before the patient has symptoms. Each year, approximately 5,000 adults in the United States alone are diagnosed with GIST Cancer. According to the American Cancer Society, many doctors misdiagnose GIST as another type of GI cancer. The lifesaving treatment for GIST is delayed and the GIST Cancer destroys lives. The overall five year survival rate of people diagnosed with a malignant tumor has been estimated to be 76%.
Looking For A GIST Cancer Doctor?
GIST is a rare form of cancer that most doctors misdiagnose or are not familiar with the appropriate treatment. If you or a loved-one is diagnosed with GIST, getting in touch with a physician who specializes in GIST Cancer is of utmost importance. These doctors and researchers deal with this disease on a daily basis and can help guide you to the right treatment.
In addition to the GIST Cancer Research Team of physicians, researchers and nurses, the following link will put you in touch with domestic and international GIST Cancer specialists.
