内容紹介
Summary
Endobronchial metastasis(EBM)is a rare complication in breast cancer patients. Herein, we report 2 cases of EBM in breast cancer patients. Patient 1 had pulmonary metastases that were treated with hormone therapy and showed long survival after achieving a CR, while patient 2 had multi-organ metastases and died 42 months after the diagnosis of EBM. If bronchial obstruction is observed in a breast cancer patient, early diagnosis of EBM via a bronchoscopic examination is recommended. EBM may not indicate a poor prognosis, and appropriate anti-cancer therapy with palliative intrabronchial therapies can prolong the survival in selected EBM patients.
要旨
まれな病態である乳癌気管支内転移(endobronchial metastasis: EBM)の2例を報告する。肺転移を伴った1例は診断後66か月,内分泌療法が奏効しCRで生存中である。多臓器に転移のあった1例は診断後42か月で癌死した。乳癌患者に気管支閉塞症状を認めた場合,気管支鏡検査で確定診断を得て患者の状況に応じた治療を行うことで,良好な予後を得られる可能性がある。
