Introduction: Most patients with HER2-positive breast cancer receive chemotherapy and trastuzumab. Data from adjuvant trials have shown that the combination of docetaxel, carboplatin and weekly trastuzumab (TCH) is well tolerated and as effective as anthracycline-containing regimes. Previous investigations on neoadjuvant treatment with taxanes, platinum salts and trastuzumab showed pathological complete remission (pCR) rates between 43.3 and 76%. To date, the longest published follow-up in this indication is 3 years. Here we present 4-year follow-up data for a cohort of 78 patients treated with neoadjuvant TCH. Methods: Between 2009 and 2014 we treated 78 patients with operable HER2-positive breast cancer with a neoadjuvant schedule of docetaxel (75 mg/m2) and carboplatin (AUC 6) every 3 weeks (q3w) and trastuzumab (4 mg/kg loading dose then 2 mg/kg) q1w. Lymph node involvement was verified by sentinel lymph node or core-cut biopsy. Patients were diagnosed at a mean age of 55.5 years; 65.4% had hormone receptor-positive tumors, 34.6% presented with grade 3 disease and 51.3% of patients were node positive. Patients were monitored every 2 cycles by ultrasound. After 6 cycles of chemotherapy all patients had surgery. Axillary dissection was performed in case of positive lymph node status prior to TCH. After surgery, trastuzumab was continued q3w up to 1 year. Results: No grade III/IV toxicities occurred and no case of congestive heart failure was observed. Neither dose modifications nor dose delays were necessary. 34 of the 78 patients (43.6%) achieved a pCR, 27 of the 40 node-positive patients (67.5%) experienced nodal conversion. After a median follow up of 48.5 months the disease-free survival (DFS) was 84.6%, the distant disease-free survival (DDFS) was 87.2% and the overall survival (OS) was 91%. Only T stage and nodal status at baseline were found to be significantly associated with survival estimates. Conclusion: The anthracycline-free regimen TCH is effective and safe in the neoadjuvant therapy of HER2-positive breast cancer, yielding DFS, DDFS and OS probabilities comparable to the results of adjuvant trials. Our data support the use of TCH as a neoadjuvant therapy regimen for patients with HER2-positive breast cancer. They also strongly encourage the use of taxanes and platinum salts as the chemotherapy backbone in studies investigating dual blockade with trastuzumab and pertuzumab in the neoadjuvant setting.

512 Background: The joint efficacy analysis of NCCTG N9831 and NSABP B-31 demonstrated improved outcomes with the addition of trastuzumab (H) to doxorubicin and cyclophosphamide (AC) followed by paclitaxel (T) in women with surgically removed HER2- positive breast cancer (NEJM 2005). Following this report, patients randomized to AC→T and less than 6 months from completion of chemotherapy were eligible to receive H. We have updated the initial combined results of these two trials. Methods: Primary and secondary efficacy endpoint were disease free survival (DFS) and overall survival (OS). Cox modeling was performed. Hazard ratios are adjusted for nodal status, tumor size, T schedule, hormone receptor status, and trial (also age for OS). Results: Among the 3,969 women enrolled (ages: 22 to 80yrs), there have been 619 events (H group: 222, non-H: 397). First events were: recurrence (511), contralateral breast disease (18), other second primary cancers (48), and death without recurrence or second primary cancers (42). The median follow-up among the 3,711 women still alive is 2.9 years (range up to 6,4 years). The 4 yr DFS rate and 4 yr OS rate respectively were: 85.9% (95%CI: 84.0–87.8%) and 92.6% (95%CI: 91.2–94.2%) in H group and 73.1% (95%CI: 70.6–75.8%) and 89.4% (95%CI: 87.6–91.2%) in non- H group. Hazard ratio for adjuvant (H/non-H) was 0.49 (P<0.0001; 95%CI: 0.41–0.58) for DFS and 0.63 (P=0.0004; 95%CI: 0.49–0.81) for OS.The rates of a first event per 1,000 women/year during yrs 1–4 were: 26.7, 52.9, 49.6 and 23.2 for H and 42.3, 102.3, 107.6 and 61.5 for non-H. The impact of crossover on clinical outcome will be explored. Conclusions: With an increase in the median follow-up of 11 months and with 225 additional events, the demonstration of substantial improvement in outcomes with the addition of trastuzumab to chemotherapy persist. This improvement continues in spite of some degree of cross-over occurring after the initial results were reported.Updated data regarding crossover outcomes and H duration (as they relate to disease free survival) will be presented.

540 Background: We previously reported the cardiac safety results and distant disease-free survival (DDFS) on a phase 2 trial of dose-dense (dd) doxorubicin and cyclophosphamide (AC) followed by paclitaxel (T) and trastuzumab (H) in patients with early stage, human epidermal growth factor receptor 2 (HER2)-positive breast cancer. The incidence of congestive heart failure (CHF) was 1.4% both at a median follow-up of 2 and 7 years. Here, we report updated CHF and DDFS rates with longer follow-up. Methods: Patients were enrolled with HER2 overexpressed (immunohistochemistry 3+) or amplified (fluorescent in situ hybridization ratio > 2.0) disease, regardless of size or nodal status, and baseline left ventricular ejection fraction (LVEF) of > 55%. Patients (pts) received dd AC (60/600 mg/m2) q 2 weeks (w) x 4 →T (175 mg/m2) q 2 w x 4 with H (loading dose 4 mg/kg → 2 mg/kg q w during T → 6 mg/kg q 3 w for rest of 1 year); pegfilgrastim was administered after each chemotherapy cycle. LVEF monitoring with multigated acquisition scan occurred at baseline, months 2 (after AC), 6, 9, and 18 (after therapy completion). Results: From January 2005 to November 2005, 70 pts were enrolled; 2 (3%) and 68 (97%) were treated in neoadjuvant and adjuvant settings, respectively. In 68 pts treated in adjuvant setting, 40 (60%) and 27 (40%) had node-positive and node-negative disease, respectively. The median age was 49 years old (range 27-72); 55 (79%) had hormone-receptor positive disease, 11 (16%) had hypertension, and 21 (30%) had left sided radiation. The median baseline LVEF was 68% [range, 55%-81%]). With a median follow-up of 10.9 yrs, there was no additional CHF event. Therefore, the cumulative incidence of CHF remains to be 1.4% (95% confidence interval [95% CI], 1.36%- 7.7%). The 9 and 10 year DDFS rates were 89% (95% CI, 78%-94%) and 87% (95% CI 75%-93%), respectively. Conclusions: Longer follow-up of this study has demonstrated that ddAC →TH is associated with a low risk of CHF and promising DDFS in patients with early-stage HER2-positive breast cancer.
