[A long-surviving patient with Stage IV breast cancer with no recurrence after combined therapy of medroxy progesterone acetate (MPA) and intra-arterial infusion chemotherapy].

The patient is a 42-year-old woman who had advanced (Stage IV) right breast cancer with contralateral supraclavicular lymph node metastasis. She was treated with the combined use of MPA and the intra-arterial infusion chemotherapy. We administered EPI into the left subclavian artery and the right internal thoracic artery. Total dose of EPI was 210 mg. MPA was administered po at 1,200 mg/day daily. During the chemotherapy, she experienced only grade 2 alopecia. After the chemotherapy, the regressive change was noted in the primary lesion. The clinical response was evaluated CR. She underwent right modified mastectomy and the resection of contralateral supraclavicular lymph nodes. Although the clinical response was very good, the pathological effect was only Grade 1b. Eight years have passed since the operation, and the patient is still alive with no sign of recurrence. It is suggested that this combination therapy may be useful for advanced breast cancer and the like.
