| Outline of Final Research Achievements |
This study enrolled 45 gynecological cancer patients who underwent surgical treatment followed by TC-chemotherapy. The elevated triglyceride (TG) group included patients who exhibited hypertriglyceridemia during TCchem, and the stable TG group included patients with a normal TG level. Fibrate group exhibiting hypertriglyceridemia during TCchem were administered bezafibrate. Endothelial dysfunction was evaluated by FMD measured before and immediately after the final TCchem. HUVECs were used to elucidate the biological mechanisms.
RESULTS:The administration of TCchem induced hypertriglyceridemia in 66 percent of the participant. The decrease in %FMD induced by TCchem improved following treatment with bezafibrate. An in vitro examination demonstrated TCchem attenuated nitric oxide production and PPARα activity in HUVECs, which was partially improved by bezafibrate.
CONCLUSION:Bezafibrate prevents endothelial dysfunction induced by TCchem via TG-dependent and TG-independent mechanisms.
