[Successfully treated locally advanced breast cancer by intra-arterial infusion chemotherapy: a case report]

A 40-year-old female was admitted to our hospital with a large right breast tumor that was over 15 cm in diameter. We treated this locally advanced breast cancer by intra-arterial infusion chemotherapy. Through a catheter placed in the right subclavian artery, doses of 20-30 mg of ADM were injected intermittently with MMC and 5-FU. When a total of 120 mg of ADM had been infused, leukopenia developed, but this was immediately improved by G-CSF. With this treatment, her breast tumor and lung metastases were almost completely disappeared. Thus, an intra-arterial infusion chemotherapy was considered to be an effective treatment for locally advanced breast cancer.
