RESUMO
BACKGROUND: Brain metastasis from breast cancer has a poor prognosis. For solitary cerebral metastases, surgical resection may contribute to the improvement of survival and QOL. We studied the prognosis and characteristics of solitary brain metastasis from breast cancer in patients undergoing surgical resection. METHODS: Seventeen patients had tumors metastatic to the brain at Kasukabe Municipal Hospital between June 2009 and May 2016, and 7 of them underwent craniotomy. Their treatment outcomes were analyzed retrospectively. RESULTS: The median age at diagnosis of brain metastasis was 56 years. The median survival duration was 19.6 months. With regard to radiation therapy after surgery, 3 patients received whole brain irradiation, 2 patients received stereotactic brain irradiation, and 2 patients received both. The site of brain metastasis was the cerebellum in 6 patients, and the occipital lobe in 1 patient. The number of HER2-positive breast cancer patients was 5, and lapatinib and capecitabine were administered to 4 out of these 5 patients. CONCLUSION: For solitary brain metastasis, the improvement in symptoms and the extension of the survival can be achieved using multidisciplinary treatment with surgery, radiation, and molecular targeting drugs.
