Welcome to Ariana Majer, a PhD student in the CAMB-Cancer Biology Program, who is joining the lab to work on understanding the role of menin in hereditary colon polyposis syndromes.
Welcome also to Lily Altman, an undergraduate student at the University of Virginia, who is joining the lab for the summer.
Marya Pulaski presented her research examining the yield of gastric biopsies in Lynch syndrome at Digestive Disease Week in Chicago, IL.

Welcome to Sam Levy, a Master's in Genetic Counseling graduate student, who joined our group and will be examining patient decision-making about CDH1 testing on multigene panel testing.
December 2022
In an effort led by Kole Buckley, we published the first comprehensive review of BRCA1- and BRCA2-associated gastric cancer in Cancers.
November 2022
Bryson Katona presented results from our study of the yield of multigene panel testing in patients with colorectal cancer at the CGA-IGC Annual Meeting in Nashville. Excitingly these results were simultaneously published in JCO Precision Oncology, and picked up the ASCO Daily News. To date, this is the largest study examining outcomes of multigene panel testing in colorectal cancer patients, and it showed that there was a high rate of clinically actionable variants detected across all age groups, all panel sizes, and all racial/ethnic groups. This data supports broadening germline genetic testing criteria for colorectal cancer patients.
Also at the CGA-IGC Annual Meeting in Nashville, Sam Williams presented her thesis work looking at outcomes of in-person versus telehealth GI cancer genetic appointments as a Poster of Distinction. Her poster was also selected as one of the posters featured on the Poster Walk!
October 2022
Welcome to Marina Weber who joined the group as a Clinical Research Coordinator.
July 2022
Welcome to Kole Buckley who joined the group as a Post-Doc. Kole's research will be focused on understanding gastric carcinogenesis in hereditary gastric cancer predisposition syndromes and using immune-interception as a mechanism for gastric cancer risk reduction.
June 2022
Welcome to Michaela Dungan and Tasnim Eba, who both joined the group as Clinical Research Coordinators. Congratulations to Thomas Nyul who transitioned to a Research Specialist A in our group.
The initial results from the multicenter CAPS5 study (Penn site PI - Katona) were published in the June issue of the Journal of Clinical Oncology. Excitingly the study showed that the majority of pancreatic cancers detected on surveillance in high-risk individuals were stage I and had long-term survival, providing much needed evidence to support the efficacy of pancreatic surveillance in high-risk populations.
April 2022
An exciting paper that our group contributed to was published in Nature, showing how beta-hydroxybutyrate suppressed colorectal cancer (Nature paper). To continue the exciting momentum in this area we opened a new clinical trial simultaneously with publication of the manuscript, that is the first study in humans to examine the the role of beta-hydroxybutyrate supplementation in colorectal cancer prevention (Clinical trial information).
February 2022
Published in the February issue of Cancers is the first comprehensive review of upper gastrointestinal cancer surveillance in Lynch syndrome. Including data from our experience at Penn, current data is supportive of upper gastrointestinal cancer surveillance as an effective method to identify precancerous lesions and early-stage cancers in Lynch syndrome.
January 2022
Welcome to Isabel Anez Bruzual, a Master's in Genetic Counseling graduate student, who joined our group and will be examining the perceived utility and psychological impact of pancreatic cancer screening in high-risk populations.
November 2021
Published in the November issue of World Journal of Clinical Oncology, we report on the outcomes of screening for small bowel and urinary tract cancer in Lynch syndrome, showing that broad incorporation of these modalities into Lynch syndrome care is unlikely to helpful.
September 2021
Welcome to Keely Beyries, who joined our group as a Research Specialist A, as well as Thomas Nyul who joined as a Student Researcher. Congratulations also to Taylor Hojnacki for her promotion to Research Specialist B.
August 2021
This month, published in Cancer Prevention Research, we report our outcomes of pancreatic cancer surveillance in BRCA1, BRCA2, PALB2, and ATM carriers, and illustrate that surveillance can be considered in these individuals at increased pancreatic cancer risk.
June 2021
Welcome to Daniel Clay, who joined our group as a Clinical Research Assistant. Jessey Yang, who is a current University of Pennsylvania undergraduate student, also joined our group.
April 2021
Now published in Pancreatology, the COVID-19 pandemic led to significant disruptions in pancreatic cancer surveillance amongst high-risk individuals in the multi-center CAPS5 Study.
February 2021
Welcome to Jordan Heiman, who joined our group as a Clinical Research Coordinator.
Just published in Cancer Prevention Research, COVID-19 led to significant disruptions in Lynch syndrome surveillance, especially amongst young individuals.
January 2021
Welcome to Samantha Williams, a Master's in Genetic Counseling graduate student, who joined our group and will be examining the effects of telehealth use during the pandemic on GI cancer genetic testing outcomes.
October 2020
Our multi-institutional collaborative effort defining the distinct different phenotype of mutation-negative Juvenile Polyposis Syndrome was published in Cancer Prevention Research.

Just published in Molecular Cancer Therapeutics, menin represses glycolysis in colorectal cancer cells, which in combination with autophagy protects colorectal cancer cells from small molecule EGFR inhibitors.
Upper GI cancers are observed in Li-Fraumeni syndrome and upper GI surveillance should be a part of LFS surveillance. These results were just published in the American Journal of Gastroenterology.
August 2020
Welcome to Gillain Constantino, who joined our group as a Clinical Research Coordinator.
The largest report to date of upper GI surveillance in Lynch syndrome demonstrates that upper GI cancers are detected during surveillance at a lower stage than those detected outside of surveillance. These results were published in Cancer Prevention Research.
March 2020
Disparities in race, health insurance coverage, and medical status exist in GI cancer risk assessment appointment completion, showing that we have work to do to ensure equitable access to these important GI cancer risk assessment services. These results were published in a Special Issue of the Journal of Genetic Counseling entitled "Minority and Health Disparities in Research and Practice in Genetics Counseling and Genomic Medicine."
February 2020
Welcome to Jeshua DeJesse, a Master's in Genetic Counseling graduate student, who joined our group and will be looking at uptake and outcomes of extracolonic screening in Lynch syndrome.
