Researchers at Karolinska Institutet and Karolinska University Hospital have identified biomarkers in the blood that can distinguish gallbladder cancer from gallbladder inflammation, a discovery that could lead to fewer unnecessary operations and better treatment decisions for patients. The study has been published in the journal JHEP Reports.
Gallbladder cancer and gallbladder inflammation, also known as cholecystitis, are challenging to differentiate using current diagnostic methods. This diagnostic difficulty often results in patients undergoing extensive surgery unnecessarily. However, scientists at Karolinska Institutet have now pinpointed eight specific proteins in the blood that can distinguish between these conditions with high accuracy.
Machine Learning and Proteomics Lead to Breakthrough
The researchers analyzed blood samples from 82 patients at Karolinska University Hospital who were suspected of having gallbladder cancer. Using advanced techniques such as machine learning and proteomics—which involve large-scale analysis of protein structure and function—they examined 7,500 different proteins and identified 651 that varied depending on whether a patient had cancer or inflammation. Among these, eight proteins demonstrated particularly high diagnostic accuracy.
“Our results show that these proteins could be used to develop a non-invasive test that could help doctors make better decisions before surgery. This could reduce the number of unnecessary surgeries and improve patients’ quality of life,” said study first author Ghada Nouairia, assistant professor at the Department of Medicine, Huddinge, Karolinska Institutet.
Implications for Future Medical Practice
The next phase of this research involves validating these findings in larger studies and developing clinical tests that can be integrated into routine medical practice. “This discovery is an important step in precision medicine to improve the diagnosis of gallbladder cancer and make it more personalized,” added Nouairia.
Researchers are hopeful that their findings will lead to better diagnostic tools and ultimately improve patient care for those suspected of having gallbladder cancer.
