OBJECTIVE: To observe the effect of continuous intra-arterial chemotherapy and embolization in the treatment of locally advanced breast cancer. METHODS: A preoperative superselective regional arterial catheter infusion chemotherapy combined with a secondary arterial embolization protocol was performed in 9 patients with stage IIIa and b breast cancer. RESULTS: Good results were obtained within 1 month after treatment, with an effective rate of 89% (8/9). Conclusion: Preoperative regional arterial continuous infusion chemotherapy combined with secondary arterial embolization in locally advanced breast cancer can effectively improve the efficacy of preoperative chemotherapy, significantly shorten the course of treatment, and the toxicity is small and simple. It is worthy of popularization and application.
