Our main projects are the diagnostic method, evaluation method of disease status and new treatment method of malignant melanoma. Because progressed melanoma is difficult to cure, early diagnosis and treatment are very important for patients. Sometimes, it is difficult to distinguish the early melanoma from the benign pigmented nevus. We aim to establish the new diagnosis methods using photographs and a noninvasive method using the nail pieces. Today, immune checkpoint inhibitors（ICI） and molecular target therapy are often used for the patients suffered from progressed melanoma. We search for ICI effect predictors. We also develop virotherapy againt melanoma in collaboration with the Institute of Medical Scinence, The University of Tokyo.
Since malignant melanoma is one of the aggressive cancers, once it progress, complete remission is difficult. Even using immune checkpoint blockade, objective response rate is up to 30%. We hope that outcomes of our study contribute for improvement both of early diagnosis and treatment of advanced melanoma.
