| Outline of Final Research Achievements |
The purpose of this study was to clarify the characteristics and the molecular mechanisms of cardiotoxicity due to molecular targeted drugs in cancer patients. We built the database of cancer patients who started molecular targeted drugs. And we investigated the clinical characteristics of cardiotoxicity, such as biomarker, diagnostic imaging, and the relationship with the prognosis of cancer patients. Our studies revealed that hypertension and proteinuria was observed in cancer patients treated with angiogenesis inhibitors bevacizumab (Bev) at high frequency. And we analyzed the change of the endothelial cell proliferation factor before and after Bev administration in cancer patients. A significant increase in serum VEGF levels was observed in cancer patients treated with Bev, although HGF and FGF-23 level did not show a significant change. Further examination is required to evaluate the early parameter of cardiotoxicity and to elucidate cardiotoxic molecular mechanisms.
