We looked at the literature and knew by experience that when you look at these scans – and these patients might have had previous scans and when you look at those previous scans, you can already see changes in the tissue indicative that something could be wrong. That’s the group we’re focusing on, and that number could be quite high.” Studies suggest that around 40-60% of patients with pancreatic cancer had previous CT scans that could have indicated early tissue changes. Routine CT scans are particularly important here because, unlike some other cancers, there are no biomarkers in the blood or urine to indicate pancreatic cancer. Without more focused or niche research, CT scans are the only way to identify potential malignancies. “Many people are working on finding a biomarker that will be the holy grail for pancreatic cancer,” John reveals. “There have been some promising ideas, but nothing applicable in the clinic yet.” PANORAMA is the first-ever largescale study comparing radiologists
