Research Focus

Development of predictive factors for the effectiveness of preoperative immunochemotherapy

For primary breast cancer patients, we will analyze factors related to the effectiveness and resistance of preoperative immunochemotherapy and develop a prediction system. We will proceed by integrating molecular, histopathological, and imaging factors.

Development of drug therapies, including new immunotherapy

We will proceed with an approach that will enhance the effectiveness of immunotherapy and overcome resistance. We will develop various combination therapies with immunotherapy and analyze immune memory.

Development of clinical systems that enable early detection, appropriate evaluation, and response to treatment-related toxicity
