    Summary:
    An artificial intelligence (AI) tool can accurately predicted who
    would develop pancreatic cancer based on what their CT scan images
    looked like years prior to being diagnosed with the disease. The
    findings may help prevent death through early detection of one of
    the most challenging cancers to treat.



    FULL STORY ==========================================================================
    An artificial intelligence (AI) tool developed by Cedars-Sinai
    investigators accurately predicted who would develop pancreatic cancer
    based on what their CT scan images looked like years prior to being
    diagnosed with the disease. The findings, which may help prevent death
    through early detection of one of the most challenging cancers to treat,
    are published in the journal Cancer Biomarkers.


    ========================================================================== "This AI tool was able to capture and quantify very subtle, early signs
    of pancreatic ductal adenocarcinoma in CT scans years before occurrence
    of the disease. These are signs that the human eye would never be able to discern," said Debiao Li, PhD, director of the Biomedical Imaging Research Institute, professor of Biomedical Sciences and Imaging at Cedars-Sinai,
    and senior and corresponding author of the study. Li is also the Karl
    Storz Chair in Minimally Invasive Surgery in Honor of George Berci, MD.

    Pancreatic ductal adenocarcinoma is not only the most common type of
    pancreatic cancer, but it's also the most deadly. Less than 10% of people diagnosed with the disease live more than five years after being diagnosed
    or starting treatment. But recent studies have reported that finding
    the cancer early can increase survival rates by as much as 50%. There
    currently is no easy way to find pancreatic cancer early, however.

    People with this type of cancer may experience symptoms such as general abdominal pain or unexplained weight loss, but these symptoms are often
    ignored or overlooked as signs of the cancer since they are common in
    many health conditions.

    "There are no unique symptoms that can provide an early diagnosis
    forpancreatic ductal adenocarcinoma," said Stephen J. Pandol, MD,
    director of Basic and Translational Pancreas Research and program
    director of the Gastroenterology Fellowship Program at Cedars-Sinai,
    and another author of the study. "This AI tool may eventually be used to
    detect early disease in people undergoing CT scans for abdominal pain or
    other issues." The investigators reviewed electronic medical records
    to identify people who were diagnosed with the cancer within the last
    15 years and who underwent CT scans six months to three years prior to
    their diagnosis. These CT images were considered normal at the time they
    were taken. The team identified 36 patients who met these criteria, the majority of whom had CT scans done in the ER because of abdominal pain.

    The AI tool was trained to analyze these pre-diagnostic CT images from
    people with pancreatic cancer and compare them with CT images from 36
    people who didn't develop the cancer. The investigators reported that the
    model was 86% accurate in identifying people who would eventually be found
    to have pancreatic cancer and those who would not develop the cancer.

    The AI model picked up on variations on the surface of the pancreas
    between people with cancer and healthy controls. These textural
    differences could be the result of molecular changes that occur during
    the development of pancreatic cancer.

    "Our hope is this tool could catch the cancer early enough to make it
    possible for more people to have their tumor completely removed through surgery," said Touseef Ahmad Qureshi, PhD, a scientist at Cedars-Sinai
    and first author of the study.

    The investigators are currently collecting data from thousands of
    patients at healthcare sites throughout the U.S. to continue to study
    the AI tool's prediction capability.

    Funding: The study was funded by the Board of Counselors of Cedars-Sinai Medical Center, the Cedars-Sinai Samuel Oschin Comprehensive Cancer
    Institute and the National Institutes of Health under award number
    R01 CA260955.
