140 Background: Most patients with HER2-positive 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 TCH showed pCR-rates in the range of 40%, however, survival data have not yet been presented. Here we present 4.5-year follow-up data for a cohort of 51 patients treated with neoadjuvant TCH. Methods: We treated 51 patients with operable HER2-positive breast cancer with a neoadjuvant schedule of docetaxel (75 mg/m2) and carboplatin (AUC 6) q3w and trastuzumab (2(4)mg/kg) q1w. Lymph node involvement was verified by SLNB or core-cut-biopsy. Mean age at diagnosis was 55 years, 68.6% had ER positive tumors, 39.2% presented with grade 3 disease and 49% of patients were node-positive. Patients were monitored 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 one year. Results: Side effects were mild, no grade III/IV toxicities occurred and no case of cardiomyopathia was observed. 21 (41.18%) patients achieved a pCR, 18 (72.0%) patients converted from cN+ to ypN0. Outcome data at a median follow-up of 53.6 months are as follows (see table). Conclusions: Outcome following neoadjuvant TCH as observed in our analysis compares well to outcome data observed in adjuvant trastuzumab trials such as HERA or BCIRG006. Particularly among patients with ER positive disease and those experiencing axillary conversion we observed an excellent outcome. Importantly, TCH was well tolerated in our cohort. Therefore our data support the use of TCH as neoadjuvant therapy regimen for patients with HER-positive breast cancer. [Table: see text]

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.

The present commentary synthesizes the current evidence on the role of the immune response in HER2-positive breast cancer. It points out the strengths and weaknesses of the findings observed so far, particularly in the early setting, including the clinical significance of scoring tumor-infiltrating lymphocytes. A figure proposing research hypotheses for the implementation of immune checkpoint blockade use for patient candidates to neoadjuvant treatment is presented.

e12619 Background: Dual targeted therapy with chemotherapy is one of the therapeutic approaches as neoadjuvant treatment in HER2/neu positive breast cancer (BC). However the safety and efficacy data of dual-targeted, chemotherapy regimen (docetaxel, carboplatin, trastuzumab, & pertuzumab [TCH-P] is limited from the Indian subcontinent. Methods: This retrospective study aims to evaluate the efficacy and toxicity of neoadjuvant TCH-P regimen in early, locally advanced, and oligometastatic (OM) HER2-positive BC, at All India Institute of Medical Sciences, New Delhi, India, in between the period 2015-2020. Total 6 cycles of 3-weekly neoadjuvant chemotherapy (NACT) protocol containing docetaxel (75 mg/m2), carboplatin (AUC = 6), trastuzumab (8 mg/kg loading followed by 6 mg/kg) and pertuzumab ( 840 mg loading followed by 420 mg) were planned. Subcutaneous peg-filgrastim was prophylactically administered on day 2 of each cycle. The primary outcome was the pathological complete response (pCR), which was defined as an absence of invasive and noninvasive cancer in breast or lymph node and secondary outcome were clinical overall response rate (ORR), rate of breast conservation surgery( BCS) for patients for whom modified radical mastectomy( MRM)was planned and toxicity. Results: Forty-five patients with a median age of 48 years (31-65) were included in this study. The TNM (AJCC-7th edition) stage distribution was stage II, 14 (31.1%); stage III, 29 (64.5%); and stage IV (OM), 2 (4.4%). Clinical node positivity disease was found in 26 (57.8%) cases. Nineteen (42.2%) patients had hormone-positive and 26(57.8%) cases were premenopausal. The clinically ORR and CR were seen in 100% and 60% respectively. Overall pCR rate was observed in 25 (55.6%) patients (70% in stage II). BCS was performed in 23(51.1%) cases. In 12(26.6%) cases, planned MRM was changed to BCS following NACT. Grade 3 and 4 toxicities were diarrhea 7 cases, thrombocytopenia in 6, neutropenia in 4, febrile neutropenia in 1, and anemia in 2 cases. Ten patients required dose modification and interruption. No patient had congestive heart failure or induction death. Conclusions: This is the first study of the non-anthracycline-based neoadjuvant protocol in HER2 positive BC from India. The TCH-P is an effective, safe, and well-tolerated, protocol with a path CR rate of 55.6% and 26.6% BCS conversion rate from planned MRM.

BackgroundNanoparticle albumin-bound paclitaxel (nab-paclitaxel) as neoadjuvant chemotherapy (NAC) for breast cancer remains controversial. We conducted a retrospective study to compare the efficacy and safety of nab-paclitaxel with those of docetaxel as neoadjuvant regimens for HER2-negative breast cancer.MethodsIn this retrospective analysis, a total of 159 HER2-negative breast cancer patients who had undergone operation after NAC were consecutively analyzed from May 2016 to April 2018. Patients were classified into the nab-paclitaxel group (n = 79, nab-paclitaxel 260 mg/m2, epirubicin 75 mg/m2, and cyclophosphamide 500 mg/m2) and the docetaxel group (n = 80, docetaxel 75 mg/m2, epirubicin 75 mg/m2, and cyclophosphamide 500 mg/m2) according to the drug they received for neoadjuvant treatment. The efficacy and adverse events were evaluated in the two groups.ResultsThe pathological complete response (pCR)(ypT0/isN0) rate was significantly higher in the nab-paclitaxel group than in the docetaxel group (36.71% vs 20.00%; P = 0.031). The multivariate analysis revealed that therapeutic drugs, lymph node status, and tumor subtype were the most significant factor influencing treatment outcome. At a median follow-up of 47 months, disease-free survival (DFS) was not significantly different in those assigned to nab-paclitaxel compared with docetaxel (82.28% vs 76.25%; P = 0.331). The incidence of peripheral sensory neuropathy in the nab-paclitaxel group was higher than that in the docetaxel group (60.76% vs 36.25%; P = 0.008), while the incidence of arthralgia was observed more frequently in the docetaxel group (57.50% vs 39.97%; P = 0.047).ConclusionsCompared with docetaxel, nab-paclitaxel achieved a higher pCR rate, especially those patients with triple-negative breast cancer or lymph node negative breast cancer. However, there was no significant difference in DFS between the two groups. This study provides a valuable reference for the management of patients with HER2-negative breast cancer.
