N2 - Background: Pegylated liposomal doxorubicin (PLD) was shown as active but less toxic compared to doxorubicin in advanced breast cancer. Given its low cardiotoxicity, the combination of PLD and trastuzumab appears most attractive in the treatment of human epidermal factor receptor 2 (HER2)-positive breast cancer. Patients and Methods: We investigated the activity of 8 courses of PLD in combination with cisplatin and infusional 5-fluorouracil (CCF) plus 3-week trastuzumab in patients with primary or recurrent cT2-T4 a-d, N0-3, M0 any estrogen receptor (ER), HER2-positive breast cancer. Patients with ER and/or progesterone receptor (PgR) ? 10% tumors received also letrozole (plus triptorelin if premenopausal). The principal endpoint was clinical response rate; secondary endpoints were the pathologic complete response rate (pCR) and the cardiac safety of the combination. Results: Thirty-two patients were enrolled in the study and all are evaluable for response and toxicity. Fifteen patients (47%) had ER-positive tumors, 15 patients and 2 patients had ER absent and ER poor tumors, respectively. Thirteen patients (41%) had inflammatory breast cancer (IBC) and 84% of patients had clinically positive nodes. A clinical response rate of 94% (95% CI, 79%-99%) and a pCR rate of 41% (95% CI, 24%-59%) were observed. Fifty-four percent of patients with IBC obtained a pCR. Eleven patientsdiscontinued treatment before completing 8 courses as planned. No patient developed relevant cardiac toxicity. Conclusion: In this series of very locally advanced breast cancer, the combination of CCF and trastuzumab was very active obtaining an impressive rate of pCR, particularly in IBC, which merits further investigation in larger series.
