Bilateral approach of redistributed subclavian arterial infusion chemotherapy for locally advanced breast cancer spreading to the contralateral chest wall

Abstract

A catheter port system technique called redistributed subclavian arterial infusion chemotherapy (RESAIC) for locally advanced breast cancer was reported and seemed to be effective for local control and as a palliative treatment. However, when the cancer spreads beyond the medial line to the contralateral chest wall, ipsilateral RESAIC would not achieve a favorable drug distribution. We report on two patients with advanced breast cancer spreading to the contralateral chest wall in whom bilateral RESAIC was attempted. In summary, when advanced breast cancer spreads to the contralateral chest wall, bilateral RESAIC may be useful for local control or palliation.
