The breast tumor group supports pathologically the activities of Department of Breast Surgery of the Cancer Institute Hospital, where nearly 1,000 cases of breast cancers are operated annually. Breast diseases are one of the most difficult conditions in terms of pathological diagnosis on whether a lesion is benign or malignant. We perform pathological diagnosis of biopsies, surgical margins and sentinel lymph nodes during surgical procedures. For appropriate choice of treatment after surgery, (1) we examine partially resected materials thoroughly because adjuvant irradiation can be avoided for cases without tumor spread at surgical margins, (2) we classify tumors according to malignancy grade and (3) analyze immunoreactivity of tumors to hormone receptors so as to diagnose tumors from the viewpoint of therapy sensitivity.

Research activities: we analyzed relationships between pathological diagnosis and treatment results of numerous surgical materials. Also, we aim at establishment of tailor-made medicine, such as choosing most appropriate chemothepeutic agents, by close examination of needle biopsy materials taken before neoadjuvant chemotherapy.
