Ohio State University Wexner Medical Center researchers   have developed a new "virtual biopsy" that allows them to definitively diagnose cysts in the pancreas with unprecedented accuracy. This means they can eliminate precancerous cysts and potentially save lives.

Conventional standard involves testing the fluid inside the cysts. It correctly identifies them as benign or precancerous 71% of the time. Researchers found that when the virtual biopsy is added to the standard of care, the diagnostic accuracy jumps to 97%. The study is published in Clinical Gastroenterology and Hepatology.

Dr. Somashekar Krishna, a gastroenterologist and lead author of the study told Thailand Medical News via a phone interview, "Pancreatic cysts are common, and it can be difficult to distinguish the benign cysts from those destined to become cancerous, but this procedure allows us to do that quickly and with confidence. We hope that, at the end of the day, we are saving lives either by diagnosing pancreatic cancer early on before it develops into cancer, or we are preventing unnecessary surgery of a benign, harmless pancreatic cyst."

The new diagnostic method tested in the study provides doctors with a microscopic view of the cyst wall, which is produced by a tiny scope that emits laser light inside the cyst. This allows doctors to determine almost immediately if it is precancerous.

Dr Krishna, who is an associate professor in Ohio State's College of Medicine and is also affiliated with The Ohio State University Comprehensive Cancer Cente ie Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC—James) further added, "Many times, we are able to tell the patient right after the procedure. You have a precancerous cyst, and we need to send you to the surgeon to have it removed.'"

Majority of patients get diagnosed with pancreatic cysts incidentally when getting a MRI or CT scan for another reason. Nearly 40% of MRIs done of the abdomen reveal pancreatic cysts and the chance of having them increases with age.

More than 445,000 people globally die of pancreatic cancer each year, making it the third-leading cause of cancer deaths. Patients usually don't have symptoms u ntil the cancer is advanced, making early diagnosis and treatment a challenge.

The researchers from Ohio State  University are now working to train doctors at hospitals nationwide to perform this new diagnostic method and read the images provided by the scope to catch dangerous cysts and prevent pancreatic cancer for more patients. They're also working to develop artificial intelligence that will flag cases that are likely precancerous so doctors can act quickly.
