Abstract Locally or recurrent advanced breast cancers can receive arterial blood supply from various arteries, such as the internal thoracic artery (ITA), the lateral thoracic artery, and the other small arterial branchesoriginating from the subclavian artery. Failure to catheterize and subsequent formation of collateral arterial blood supply from various arteries are some of the reasons why the response to conventional selective transarterial infusion chemotherapy is limited and variable. To overcome this problem, we developed a new subclavian arterial infusion chemotherapy method using an implanted catheter–portsystem after redistribution of arterial tumor blood supply by embolizing the ITA. We named this technique (‘‘redistributed subclavian arterial infusion chemotherapy’’

(RESAIC)). UsingRESAIC, patients can be treated on an outpatient basis for extended periods of time. Eleven patients underwent RESAIC, and the complete remission and partial response rate in 10 evaluable patients was 90%: complete remission [CR] n = 4, partial remission n = 4, stable disease n = 1, and not evaluable n = 1. Three of four patients with CR had no distant metastasis, and modiﬁed radical mastectomy wasperformed 1 month after conclusion of RESAIC. The resected specimens showed no residual cancer cells, and pathologically conﬁrmed complete remission was diagnosed in each of these cases. Although temporary grade-3 myelosuppression was seen in three patients who were previously treated by systemic chemotherapy, there was no other drug-induced toxicity or procedure-related complications. RESAICproduced a better response and showed no major complications compared with other studies despite the advanced stage of the cancers.

Introduction Locally or recurrent advanced breast cancers (ABC) are deﬁned as large tumors with extensive regional lymph node involvement or direct invasion of the skinor underlying chest wall . These cancers are considered stages IIIa and IIIb according to the tumor-node-metastasis classiﬁcation system adopted by the Japanese Breast Cancer Society, which is based on the classiﬁcation system of the International Union Against Cancer . Inﬂammatory breast cancer showing extensive histologic inﬁltration of dermal lymphatics is a distinct subset.

Some previous reports showed that arterial infusion chemotherapy (AIC) was effective for ABC [3–5]. The local response rate was reported to be 70–90%, and rapid tumor regression was seen after the treatment [6–10]. However, problems associated with AIC should be resolved as will be described later. Conventionally in AIC...
