The Hirshberg Foundation is excited to announce Dr. Vikas Dudeja will be joining us at the 16th Annual Symposium on Pancreatic Cancer to discuss the potential role the gut plays in pancreas cancers.

“We are just beginning to fully understand the complexities of the relationship between the microbiome and cancer,” said Dudeja. “Our lab, and other researchers across the nation, will continue to dig into these complexities in order to better understand how we can control and cure cancers.”

Dr. Dudeja currently serves as an Associate Professor as well as the Division Director of surgical oncology at the University of Alabama at Birmingham’s Department of Surgery.

Dr. Dudeja completed his bachelor of medicine and surgery at the All India Institute of Medical Sciences (AIIMS) in New Delhi, India. He also received his master of surgery from AIIMS in 2005. Dr. Dudeja spent the next 3 years doing research on the pathogenesis of pancreatic cancer and developing novel therapies against this aggressive disease. Afterwards he received residency training in general surgery at the University of Minnesota from 2008-2013. Following his residency, Dr. Dudeja completed a complex general surgical oncology fellowship and hepato-pancreato-billiary fellowship at Memorial Sloan Kettering Cancer Center from 2013-15. Dr. Dudeja is also a Fellow of the American College of Surgeons.

On the research front, Dr. Dudeja’s laboratory focuses on deciphering the biology of the tumor microenvironment in pancreatic cancer and the interaction of gut microbiome with anti-cancer immune response. Elucidation of the mechanism and determinants of tumor recurrence is another key area studied in his laboratory. His research efforts are funded by grants from National Institute of Health (NIH), Veterans Affairs, Department of Defense and Society Grants. His work has been published in high impact journals like Gastroenterology, GUT, Clinical Cancer Research and Nature Reviews in Gastroenterology and Hepatology. He serves on the editorial board of Gastroenterology and routinely reviews manuscripts submitted to many journals including Pancreatology, eBiomedicine, Communication Biology, Annals of Surgical Oncology.

Dr. Dudeja’s clinical interests include taking care of patients with pancreatic cancer, pancreatic cyst, hepatobiliary malignancies including cholangiocarcinoma, kaltskin tumor, colorectal cancer liver metastases, and benign disease like bile duct injury and chronic pancreatitis.

The complex relationship between cancer and the microbiome is such an important piece of the puzzle and we are honored to have Dr. Dudeja present Understanding the Gut and Tumor Connection in Pancreatic Cancer.

The Hirshberg Foundation is honored to announce that Dr. Canto will discuss screening and surveillance in individuals with a high-risk for pancreatic cancer at the 16th Annual Symposium on Pancreatic Cancer.

While participating in a pancreatic cancer screening program is not appropriate for everyone, it is an important consideration for individuals with known high-risk factors. For those with particular risk factors, including family history and certain genetic syndromes that increase susceptibility to pancreas cancer, it may be appropriate to participate in a research screening program. Surveillance may also be clinically recommended in instances such as a new diagnosis of a pancreas cyst or lesion. Many experts believe that individuals with a greater than fivefold risk of developing pancreatic cancer should undergo regular early detection tests to survey their pancreas. Regular surveillance uses medical imaging and endoscopic techniques to detect precancerous lesions or early pancreatic cancer that can be surgically removed. Screening and surveillance of high-risk individuals is a topic important to our pancreatic cancer community and we are happy to have an expert in the field present more information.

Marcia (Mimi) Canto, M.D., M.H.S. is a Professor of Medicine and Oncology at The Johns Hopkins University School of Medicine. She is also the Director of Clinical Research at the Johns Hopkins Division of Gastroenterology. Dr. Canto received her Bachelor of Science degree from the University of the Philippines in Manila in 1981 (summa cum laude). She received her Doctor of Medicine degree in 1985 from the University of the Philippines and completed her training in Internal Medicine from State University of New York Sciences Center in Brooklyn, Brooklyn, New York.

Dr. Canto completed a postdoctoral fellowship in Gastroenterology-Hepatology at The Johns Hopkins University School of Medicine and received a Master of Health Science in Clinical Epidemiology from The Johns Hopkins University School of Hygiene and Public Health. Dr. Canto came back to Johns Hopkins after advanced endoscopic training at the University Hospitals of Cleveland. Her primary clinical and research interests include endoscopy, particularly the use of endoscopic ultrasound (EUS) in detecting early pancreatic cancer and its precursors. She has shown that endoscopic ultrasound can be used to detect asymptomatic precancerous lesions in patients with a family history of pancreatic cancer, downstage pancreatic cancer screen-detected pancreatic cancer, and improve survival.

A subject that we are excited to learn more about from one of the top experts in this field, we welcome Dr. Canto to educate us on Pancreatic Cancer Screening and Surveillance in High-Risk Individuals.

The Hirshberg Foundation is delighted that Dr. Mark Girgis will share the latest information in the field of pancreatic cancer detection and treatment at the 16th Annual Symposium on Pancreatic Cancer.
