The Pediatric& SDH-Deficient GIST Consortium is committed to:
Build a Consortium
Create and Expand Clinical Trials
Involve Patient Advocacy Groups
Why a Pediatric & SDH-Deficient GIST Consortium?
There is a subset of GIST which specifically affects children and young adults with a resistant form of GIST for which the current battery of drugs are not particularly effective. Since the number of these types of patients is relatively small and the nature of this subset comparatively complex, progress finding effective treatment has been difficult.
Historically, most researchers with an interest in Pediatric & SDH-Deficient GIST worked independently from other GIST researchers, with each seeing very few of these rare disease patients. The National Institutes of Health (NIH) Pediatric and Wildtype GIST Clinic was established in 2008 with the support of advocacy organizations, to bring together clinicians and patients, to begin to better understand this rare disease. After 10 successful years, this program is at a crossroads, just at a time when no standard of care for this rare disease has been defined.
Based on this need, the Life Raft Group created and convened the inaugural Pediatric & SDH-Deficient GIST Research Symposium on July 14-15th at Life Fest 2018 in Miami. The goal of the symposium was to gather key clinicians/researchers to identify KIT-independent therapies for targeting SDH-Deficient tumors in order to improve patient outcomes.
An outgrowth of the symposium was the formation of the Pediatric & SDH-Deficient GIST Consortium. The aim of the consortium is to extend and sustain the work of the NIH Clinic and other research efforts, with the ultimate goal of finding a cure through global collaboration. As patients’ survival and quality of life are dramatically impacted by this disease, it is critically urgent that the leading Pediatric & SDH-Deficient GIST experts collaborate and share data and tissue, with the goal of finding successful targeted therapies that can help keep these patients alive.

Trustee GIST Support UK
Patient Director of the PAWS-GIST Alliance UK
Patient Co-ordinator National GIST Tissue Bank
When my 15 year old daughter was diagnosed with Paediatric/Wild-type of GIST it was the worst news our family had ever received. Very little was known/available to patients with this diagnosis in the UK.
In June 2010 we attended the Paediatric, Wild-type GIST Clinic in Washington DC, hosted by Dr Su Young Kim and Dr Lee Helman. Inspired, I felt determined that UK patients should also have this facility.
Encouraged by GIST Support UK, with fundraising from families, friends, supporters and with the dedication of Dr Ramesh Bulusu, we have opened a specialist clinic for Paediatric, Adolescent, Wild-type and Syndromic GIST patients in the UK. We will shortly host our 14th PAWS-GIST Clinic at Addenbrooke’s Hospital in Cambridge.
Essential bi-products of this initiative have been the establishment of the National GIST Tissue Bank and the National GIST registry in the UK.
My beautiful daughter tragically lost her battle with this monster disease aged only twenty three.
We must continue working to improve understanding of this disease, identify specific and effective treatments and find a cure!

He then completed a fellowship in medical oncology at The University of Texas M. D. Anderson Cancer Center while serving as chief fellow. Prior to joining the University of Miami, Sylvester Comprehensive Cancer Center, he held an appointment as associate professor of medicine in the Department of Sarcoma Medical Oncology, Division of Cancer Medicine at the University of Texas M. D. Anderson Cancer Center in Houston. Dr. Trent is currently the Associate Director for Clinical Research, the Director of the Bone and Soft-tissue Sarcoma Group and Medical Director of the Precision Medicine Initiative at the Sylvester Comprehensive Cancer Center.
Dr. Trent’s interests are in the clinical and translational research of sarcomas, direct care of sarcoma patients, and education about sarcoma. As Associate Director for Clinical Research, his goal is to help Sylvester Faculty develop clinical trials that provide clinically effective and scientifically exciting therapy to cancer patients of South Florida and beyond.
The major focus of his clinical, educational and research efforts are with gastrointestinal stromal tumor (GIST), chondrosarcoma, and other sarcomas. The major efforts of Dr. Trent’s research focus on understanding the mechanisms of action and resistance of imatinib in GIST and other sarcomas while striving toward improved therapeutic options. His work involves the use of novel preoperative/postoperative clinical trials, prospectively acquired tumor tissue, cell lines, archival tissue, as well as collaborations with disciplines such as the genomics facility, surgical oncology, pathology, radiology and interventional radiology.

Dr. Margaret von Mehren was born in New York City, NY, where she received her primary and secondary education. She then matriculated at Georgetown University in Washington, DC, where she majored in Biology and minored in Philosophy, and graduated in 1985 with honors. She received her medical degree from Albany Medical College in Albany, NY. Dr. von Mehren completed an internship and residency at New York University Medical Center in New York before moving to Philadelphia for her fellowship in medical oncology at the Fox Chase Cancer Center and Temple University. After completing fellowship, Dr. von Mehren joined the faculty of the department of Medical Oncology at Fox Chase Cancer Center where she remains today as and Associate Professor and the director of the Sarcoma program. She is a member of the NCCN panel for soft tissue sarcomas and GIST task force, as well as the Intergroup GIST Task force.
Dr. von Mehren entered fellowship with an interest in immunotherapies. She developed and conducted several trials utilizing recombinant vaccines. Her exposure as a fellow to sarcoma oncology however, led her to develop an interest in the care of this diverse patient population. The need for new therapies for this group of patients afforded an opportunity to test novel compounds. Her career has now become focused on sarcoma developmental therapeutics. She has a strong emphasis on agents for advanced gastrointestinal stromal tumors, and has served as principal investigator on many trials testing novel tyrosine kinase inhibitors as well as other targeted agents for this disease. She volunteers at the NIH Wild type GIST clinic biannually. She has also led studies testing novel agents for soft tissue sarcomas such as trabectedin. Dr. von Mehren is an active collaborator with basic scientists studying GIST and other sarcomas. The GIST research group at Fox Chase Cancer Center has identified IGF-1R as a potential target for therapy. She is developing trials to evaluate agents targeting this growth factor.
