[Two cases of advanced breast cancer with distant metastasis showing long-term survival with multidisciplinary treatment including intra-arterial infusion chemotherapy].

Two cases of advanced breast cancer are reported that have had no recurrence for more than five years after multidisciplinary treatment including intra-arterial infusion chemotherapy. The first case is a 62-year-old housewife who had brain metastases. The primary lesion and distant metastases were completely responsive to irradiation combined with chemoendocrine therapy. The other one is a 38-year-old housewife with ovarian metastasis that was revealed after oophorectomy. In this case chemoendocrine therapy was added without irradiation after intra-arterial infusion chemotherapy. These cases indicate that intra-arterial infusion chemotherapy can be recommended as a component of multidisciplinary treatment even in advanced breast cancer with distant metastasis.
