Abstract
The patient underwent modified radical mastectomy (Auchincloss)+axillary lymph node dissection (Bt+Ax) for right breast cancer (T2N1M0=Stage IIB). Pathology revealed scirrhous carcinoma. The estrogen receptor (ER)/progesterone receptor (PgR)/HER2 was -/-/0, with n=2/35. Adjuvant chemotherapy with 5FU+epirubicin+cyclophosphamide (FEC) was thus performed. One year after the operation, a solitary tumor was detected at the right lung. Right partial pneumonectomy to differentiate from primary lung cancer disclosed the tumor to be metastasis of breast cancer (ER/PgR/HER2=-/-/1+). After the operation, the patient was given paclitaxel and S-1, and she has been drug free without having recurrence for more than five years.
Recurred breast cancers are commonly treated by drug therapy. In this case, surgical resection disclosed the diagnosis of metastatic breast cancer. It is considered that a cure can be a goal of surgical resection even for metastatic breast cancers if they are oligometastases. This paper deals with a rare case of a patient who survives more than 10 years after resection of lung metastasis of breast cancer.
