A 76‑year‑old female patient with a malignant phyllodes tumor underwent modified radical mastectomy and wide excision. Multiple nodules were observed in the operated wound area. Positron emission tomography‑computed tomography (PET‑CT) revealed recurrent disease in the left breast, the adjacent left third rib, the left internal mammary region and the left ilium. A novel formulation of bevacizumab (5 mg/m2, first day) in combination with liposomal doxorubicin (Lipodox, 30 mg/m2, second day) was administered for 3 cycles every 2 weeks, and subsequently wide excision was performed. Lipodox (40 mg/m2) was administered for 3 cycles every 3 weeks, starting 4 weeks after the surgery. Follow‑up whole body PET‑CT scanning, 3 and 6 months later, indicated no sign of residual hypermetabolic malignancy. Malignant phyllodes tumors do not usually respond to chemotherapy or radiotherapy. In the present case report, a novel formulation of bevacizumab in combination with Lipodox was administered as neoadjuvant chemotherapy in a patient with a malignant phyllodes tumor and preoperative tumor shrinkage was achieved, resulting in clear resection margins.
