[Superselective intra-arterial chemotherapy in breast cancer]

Forty-two patients with locally advanced breast cancer (n = 8) or recurrent breast cancer (n = 34) received regional chemotherapy (mitoxantrone 25 mg/m2 per 24 h) via the internal mammary artery or other vessels of the subclavian artery. To prevent artery thrombosis 500-1000 U heparin per hour were administered i.v. Tumour perfusion was monitored by intra-arterial angio-CT. Remission rates (CR + PR) were 100% (primary breast cancer) and 89% (recurrent tumours), respectively. Intra-arterial chemotherapy was well tolerated. No complications were noted.
