Summary:
This clinical trial studies how well minimally invasive approaches (an artificial intelligence \[AI\] powered risk tool, nurse navigation, and a sponge on a string \[SOS\] test) work in diagnosing patients with Barrett's esophagus (BE) and esophageal cancer. Esophageal cancer has a poor 5-year survival rate when diagnosed after onset of symptoms. While rising, incidence of esophageal cancer remains too low to screen the entire population. BE is a condition in which the cells lining the lower part of the esophagus have changed or been replaced with abnormal cells that could lead to esophageal cancer. Currently, patients are screened for BE based on certain risk factors (reflux, age \> 50 years, White race, family history of esophageal cancer, obesity, male sex, and smoking), followed by endoscopies and surgery for treatment. These standard procedures may result in under-recognition of BE risk due to inaccurate and difficult to use risk assessment tools, high cost, invasiveness, low access to endoscopy, and sub-optimal recognition of abnormal cells during routing endoscopy. An AI powered risk tool that integrates symptoms, health history, and laboratory values from electronic health record data may more accurately assess BE and esophageal cancer risk that manual assessment. The BE-SOS screening test combines a swallowable cell collection device with assessment of DNA, which may more accurately diagnose abnormal cells. Nurse navigation involves trained personnel assisting individuals through the screening process and completing the follow-up diagnostic test if the screening test is positive. Navigators address cultural, social, access, and logistical barriers to screening. Nurse navigation may increase completion rates of diagnostic procedures following a positive screening test. These minimally invasive approaches may enable higher rates of BE screening than currently being accomplished.
