Johns Hopkins Study Links Mild Pancreatic Duct Dilatation To Higher Cancer Risk

Pancreatic ductal adenocarcinoma is projected to go nan second-leading origin of crab decease successful nan United States by 2030, according to nan National Institutes of Health (NIH). The International Cancer of nan Pancreas Screening (CAPS) Consortium, nan American Society for Gastrointestinal Endoscopy, and nan National Comprehensive Cancer Network presently urge surveillance for high-risk individuals, including individuals pinch aggregate contiguous humor relatives who person had pancreatic crab arsenic good arsenic those identified arsenic having a familial predisposition. In a caller Johns Hopkins Medicine study funded successful portion by nan NIH, researchers recovered mild dilatation, aliases enlargement, of nan pancreatic duct is simply a crab consequence facet that should beryllium monitored successful high-risk individuals. 

The study was published successful Gastro Hep Advances successful November 2025. 

We are identifying pancreas duct dilatation arsenic an early motion of pancreatic crab successful high-risk individuals moreover erstwhile location is nary visible mass. This uncovering whitethorn lead to amended endurance if cancers are detected early."

Marcia Irene Canto, M.D., M.H.S., professor of medicine and oncology, Johns Hopkins University School of Medicine

Canto says this investigation is portion of nan CAPS Study, an ongoing, long-term, prospective cohort study of high-risk individuals pinch a familial aliases familial predisposition for processing pancreatic adenocarcinoma. The study was initiated successful 1998. Johns Hopkins Kimmel Cancer is 1 of nan foremost leaders successful pancreatic investigation and diligent care.

In this research, Johns Hopkins Medicine experts evaluated nan outcomes of a CAPS cohort of 641 high-risk individuals. During regular surveillance pinch endoscopic ultrasound and MRI, nan researchers measured nan participants' pancreatic ducts and recovered that successful patients pinch a duct diameter greater than 4 millimeters, nan chances of processing either high-grade dysplasia aliases crab increased. Moreover, participants pinch widened pancreatic ducts were much apt to create crab early.

Of nan 641 participants evaluated, 97 showed enlargement without grounds of an obstructing wide lesion; 10 of whom were diagnosed pinch neoplastic progression wrong a median of 2 years aft dilatation was first detected. The cumulative probability of pancreatic crab pinch baseline duct widening was 16% astatine 5 years and 26% astatine 10 years. Participants were 2.6 times much apt to advancement to a crab diagnosis, peculiarly those pinch much than 3 pancreatic cysts during surveillance. 

"By identifying this consequence facet early, we were capable to intervene much quickly," says Canto. "The involution would beryllium to either run aliases do overmuch much predominant imaging. It was singular really moreover pinch nan champion imaging technology, a pancreatic crab wide whitethorn not beryllium visible moreover erstwhile it is causing structural changes successful nan gland. We person an opportunity to do better."

Canto says this early informing motion of pancreatic duct dilation could beryllium a valuable uncovering identifiable pinch different kinds of diagnostic imaging, specified arsenic CT performed for unrelated wellness issues for illustration kidney stones aliases abdominal pain.

"The dilatation is simply a reddish emblem [in high-risk patients]," Canto says. "Providers should beryllium alert that it is thing that needs to beryllium addressed correct away."

Canto says nan adjacent measurement successful nan investigation is utilizing artificial intelligence to analyse imaging and objective accusation to make much circumstantial and meticulous predictions of risk.
