[Long-term follow-up study of transcatheter arterial chemotherapy in patients with advanced breast cancer].
Intra-arterial infusion chemotherapy (I.A) was applied to 32 cases with advanced breast cancer. The subclavian artery was intubated and one shot of 30 mg of adriamycin was given every 3 days, with a total dose of over 150 mg. Then mastectomy was performed after this chemotherapy. Long-term follow-up study revealed that the response rates of the primary tumor to I.A chemotherapy provided the prospects for their prognosis. The 3-and 5-year survival of good responders (% tumor regression greater than or equal to 70%) was significantly better than those of poor responders (% tumor regression less than 70%). Then, four patients with advanced breast cancer were treated with combination of I.A infusion chemotherapy of Adriamycin and photoradiation by argon laser. The mean interval time for 50% tumor regression was shorter than in the cases treated with Adriamycin alone. In vitro, the effects of the photoradiation for MCF-7 breast cancer cell line were observed only at a high concentration of Adriamycin.
