[Intra-arterial chemotherapy to improve quality of life in cases of unresectable advanced or recurrent breast cancer].

We performed repetitive intra-arterial infusion chemotherapy (I.A.) with epirubicin in order to improve the quality of life (QOL) in 3 cases with locally advanced or recurrent breast cancer which were diagnosed as surgically unresectable and seemed uncontrollable by outpatient systemic chemotherapy. The patients were admitted to our hospital for chest wall invasion, lymph node metastasis, bleeding, pain, or edema in upper extremity. Therapeutic effects included 1 case of CR and 2 cases of PR in the primary site, and similar effects were obtained in metastasized lymph nodes. We could perform mastectomy in both of the 2 cases with locally advanced cancer after I.A., Although leukocytopenia, which was the dose limiting factor in this regimen, was observed in all 3 cases, it was Grade 2 or 3 and recovered by G-CSF. With regard to their QOL, symptoms which had driven them to inpatient treatment remarkably improved in all of the cases. Thus, after 2 series of I.A. they could receive maintenance systemic chemotherapy as outpatients. Our findings showed that the I.A. as a local control treatment in patients with unresectable advanced or recurrent breast cancer is useful for the improvement of their QOL.
