乳癌の病理組織診断

Abstract

生検の病理組織診断で浸潤性乳癌と診断された場合，癌の組織型，組織学的グレード，サブタイプ分類のための免疫染色を行い，治療法のための情報を提供する．治療で乳房を切除された場合には手術摘出標本での病理診断が最終（確定）診断となる．当院では up-to-dateな情報も取り入れつつ，標準的な乳癌の病理診断を行っている．

Pathological diagnosis of invasive breast cancer is usually made using needle core biopsy specimen．Once invasive breast carcinoma is diagnosed，it is classified into invasive carcinoma of no special type or special subtypes and histological grade is assessed．Furthermore，it is classified into five molecular “ intrinsic” subtypes using immunohistochemistry， which is very important to decide the treatment procedure and also predict prognosis．We perform the standard procedure of the pathological diagnosis of breast cancer adopting up-to-date information as well．
