Sugar Surge Fuels Ovarian Cancer Spread, Study Finds

Ovarian cancer cells that survive chemotherapy treatments may release a sugar, fructose, which subsequently signals nearby cancer cells to spread. This finding from The Wistar Institute, published in Nature Aging, offers a potential explanation for the frequent recurrence of ovarian cancer. Researchers observed that even without prior chemotherapy, high dietary fructose levels, comparable to those in sugary beverages, can promote cancer dissemination.

This preclinical research indicates that the molecules released by surviving cancer cells, rather than the cells themselves, are key drivers of metastasis. While the study focused on ovarian cancer, additional research is needed to determine if these findings are applicable to other tumor types. The implications could lead to new treatment strategies, including dietary modifications to limit processed foods high in fructose and potential repurposing of existing diabetes drugs.

Furthermore, the study raises questions about cholesterol-lowering statin drugs, as they were found to weaken cancer cell connections, potentially affecting chemotherapy response. Given that ovarian cancer is most prevalent in postmenopausal women often taking statins, this warrants further investigation into drug combinations.
