Sweet Signal: Fructose Secreted by Chemo-Treated Cells May Drive Ovarian Cancer Spread

Researchers at The Wistar Institute report that fructose released by chemotherapy-surviving ovarian cancer cells acts as a signal to neighboring tumor cells, promoting detachment and metastatic spread. In preclinical tests, high dietary fructose could enhance cancer spread by lowering cholesterol production in nearby cells, weakening cell adhesion; the finding also suggests interactions with cholesterol-lowering drugs (statins). While intriguing, these effects have not been tested in patients, and researchers caution against changing medications yet. More studies are planned to see if this pathway affects other cancers and whether diet or statin use could influence outcomes.
