Abstract 3859


The addition of trastuzumab (TH) to primary chemotherapy in HER2-positive breast cancer (BC) significantly improved pathological complete response (pCR) and survival. Concurrent use of TH to an anthracycline taxane-based regimen increased pCR but raised concerns about cardiac toxicity. Given the lower cardiotoxicity of liposomal doxorubicin hydrochloride (MYOCET®), the objective of this study was to explore the benefit of liposomal doxorubicin hydrochloride plus TH in a neoadjuvant scenario.


Patients with stage II-III HER2-positive BC were randomized to liposomal doxorubicin hydrochloride (60 mg/m2) plus cyclophosphamide (600 mg/m2) and TH (MCH) or conventional doxorubicin plus cyclophosphamide alone (AC), each followed by docetaxel (100 mg/m2) and TH. The primary objective of this trial, carried out in 21 European centers, was efficacy assessed by BC-pCR; secondary objectives included pCR by hormonal status and disease stage, progression-free survival (PFS) at 5 years, and safety.


From Mar 2008-Oct 2010, 126 patients were enrolled and were evaluable. No statistically significant differences were observed in demographics and baseline clinical characteristics between treatment groups. Adverse events and discontinuations during cycles 1-8 were similar in both treatment groups. pCR was 41.3% for the MCH group and 54.0% for the AC but differences were not statistically significant (p =.154, 95% CI −0.30 to 0.05). However, in patients with stage II disease, pCR was 31.0% vs 62.5% in favor of AC (p =.004; 95% CI 0.52-0.11). PFS was similar in both arms. The safety profile was similar in both groups; however, more patients in the AC group (12.7%) experienced cardiovascular events than in the MCH group (6.5%).


MCH was similar in efficacy to the traditional regimen of AC in terms of pCR in HER2-positive BC. However in stage II patients alone, the AC arm had a significant benefit in terms of pCR. More patients in the AC group experienced cardiovascular events than in the MCH group.
