Nonpegylated liposomal doxorubicin (nPLD) in neoadjuvant treatment of local advanced breast cancer (LABC) patients (pts).

e11514 Background: Anthracycline is very effective in treatment of breast cancer, however it can cause cardiac toxicity events. nPLD has greater safety profile and comparable efficacy than conventional anthracyclines. We evaluated safety and efficacy, in neoadjuvant setting, of nPLD in pts with LABC. Methods: 11 pts (median age 57 years). Their clinical stage was: stages IIA and IIB 1 pt respectively, IIIB 7 pts, IIIC 2 pts. 8 pts presented at diagnosis with cT4 disease. All pts were treated with nPLD (50 mg/mq, d1q21) plus Docetaxel (75 mg/mq, d1q21) and Cyclophosphamide (500 mg/mq, d1q21); only 1 pt received Cyclophosphamide, nPLD and Trastuzumab. At beginning of therapy, overall population had left ventricular ejection fraction (LVEF) ≥55%. Results: After a median of 4 chemotherapy cycles, we observed following clinical response: stable disease 2 pts (18%); partial response 7 pts (64%); complete response 2 pts (18%). 9 pts were evaluable for radiological response: objective response rate and clinical b...
