Fructose Fuels Ovarian Cancer Spread Post-Chemo

In a significant preclinical study, researchers have identified fructose as a key nutrient that promotes the spread of ovarian cancer following chemotherapy. Cancer cells that survive chemotherapy enter a state of senescence, ceasing division but remaining active. These surviving cells release signaling molecules, including fructose, which instructs other cancer cells to multiply and metastasize.

The study found that fructose released by senescent ovarian cancer cells reduces cholesterol production in neighboring cancer cells. Cholesterol normally acts as a 'cellular glue,' holding cells together. Its reduction allows cancer cells to detach more easily and spread throughout the body.

Furthermore, the research indicated that a diet high in fructose alone can accelerate cancer spread, even without chemotherapy. This suggests that dietary choices may play a role in cancer progression, although further human studies are needed.

These findings shift the understanding of chemotherapy's impact, showing it can alter surviving cells' functions. Researchers are now exploring FDA-approved drugs for diabetes to potentially reduce fructose production by these surviving cells, aiming to block metastasis.
