| Outline of Final Research Achievements |
The main goal of present study was to determine the impact of visceral obesity-induced insulin resistance and chronic inflammation on breast cancer chemotherapy for Japanese patients. Present study showed that visceral obesity worsened the survival outcome after completion of neo-adjuvant chemotherapy via insulin resistance. Furthermore, the quality of visceral fat tissue evaluated by computed tomography was significantly associated with the degree of insulin resistance, which indicated that evaluation of the quality of visceral fat tissue is also important in addition to the quantification.
