1076 Background: There is no standard treatment strategy for patients with locally advanced or metastatic breast cancer suffering progression after one prior chemotherapy with metastasis setting. Apatinib is a tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor 2(VEGFR-2). Etoposide is a highly active chemo-drug in the treatment of advanced breast cancer, both as a single agent or in combination regimens, and is well tolerated, with a low incidence of severe toxicity. This study is performed to assessed the efficacy and safety of apatinib and oral etoposide in patients with HER2 negative locally advanced or metastatic breast cancer for whom at least one lines of prior chemotherapy had failed. Methods: This open-label, single arm study enrolled patients with HER2-negative breast cancer, pretreated with anthracycline, taxanes, and who failed in the metastatic setting at least one prior chemotherapy regimens and at least one endocrine drug for hormone receptor-positive patients. Apatinib was administered 425/500mg daily according to patients ECOG(Eastern Cooperative Oncology Group) status, oral etoposide was administered 50mg/m2 for first 10 days in a 21-days cycle. The primary end point of this study was progression free survival (PFS). Secondary end points included objective response rate (ORR), disease control rate (DCR), overall survival (OS), and toxicity. The treatment duration is until disease progression or intolerability of apatinib or oral etoposide. Results: 20 eligible patients were enrolled in this, open-label, single arm study and received apatinib and oral etoposide with a median age of 54 years old(range 36 to 66 years). Median follow-up time was 11months. 20 patients were eligible for efficacy analysis. Median PFS was 5.6 months (95% confidence interval (CI), 4.01 m – 8.42 m). ORR was 20% (4/20). DCR was 70% (14/20). Median OS was 11.2 months (95% CI, 9.6 m – 14.95 m). The most common grade 3/4 treatment-related AEs were hypertension (30%), and proteinuria (5%), nausea (5%). 35%(7/20) patients had dose reduction because of adverse events, after that all adverse events can return to less than 2 grade. Conclusions: Apatinib with oral etoposide exhibited objective efficacy in pretreated, metastatic HER2-negative breast cancer with manageable toxicity. Prospective studies enrolling more patients are needed. Clinical trial information: NCT03535961.

1082 Background: Conventional chemotherapy combined with novel molecular targeted agents has been proven effective and tolerable in metastatic breast cancer (MBC). Taxanes (T) plus bevacizumab (B) and T plus capecitabine (X) showed a benefit in progression free survival (PFS) compared to T alone. Life-threatening or highly symptomatic situations require poly-chemotherapies in MBC patients; therefore a combination of all 3 drugs appears reasonable. Methods: TABEA (NCT01200212) is a prospective, randomized, open label, phase III trial comparing T plus B +/- X as 1st-line therapy in MBC. Patients with histologically confirmed HER2- locally advanced or MBC were included. All patients received T (paclitaxel 80 mg/m2 i.v. d1,8,15 q22 or docetaxel 75 mg/m2 i.v. d1 q22) and B (15 mg/kg i.v. d1 q22) (TB) and were randomized to X (1800 mg/m² daily d1-14 q22) in addition and concurrently to TB (TBX) or TB alone. Randomization was stratified by receptor status, planned taxane, and disease free interval (≤ or >12 months). Primary objective was PFS. Secondary objectives were response rate and duration, clinical benefit rate (CR, PR, stable disease ≥ 24 weeks), 3yr overall survival, PFS in patients ≥ 65 years, toxicity, and compliance. Sample size calculation assumed a PFS of 10 and 13.3 months for TB and TBX, respectively (HR=0.75) requiring 432 patients and 386 events with 2-sided α=0.05 and β=0.2. Interim analysis was planned after 25% of required events (n=96). Results: Planned interim futility and safety analyses after 100 documented events in 202 patients have shown no efficacy benefit and higher toxicity in the TBX arm. For PFS, HR=1.061, 95% CI (0.715, 1.576) was observed, futility boundary was crossed. Overall grade 3-4 adverse events (e.g., thrombopenia, diarrhea, hand-foot-syndrome) (72.3 vs. 57.4%, p=0.039)and serious adverse events (40.6 vs. 24.8%, p=0.016) rates were higher for TBX after 16.3 months median follow up. There were 6 deaths in the TBX vs. 1 in the TB arm. Recruitment and therapy were stopped on 5th Oct 2012 following the advice from the IDMC. Conclusions: TABEA failed to show an improvement using the 3 drug regimen TBX in high-risk MBC patients. Clinical trial information: NCT 01200212.

Purpose In this study, two doses of temsirolimus (CCI-779), a novel inhibitor of the mammalian target of rapamycin, were evaluated for efficacy, safety, and pharmacokinetics in patients with locally advanced or metastatic breast cancer who had been heavily pretreated. Patients and Methods Patients (n = 109) were randomly assigned to receive 75 or 250 mg of temsirolimus weekly as a 30-minute intravenous infusion. Patients were evaluated for tumor response, time to tumor progression, adverse events, and pharmacokinetics of temsirolimus. Results Temsirolimus produced an objective response rate of 9.2% (10 partial responses) in the intent-to-treat population. Median time to tumor progression was 12.0 weeks. Efficacy was similar for both dose levels but toxicity was more common with the higher dose level, especially grade 3 or 4 depression (10% of patients at the 250-mg dose level, 0% at the 75-mg dose level). The most common temsirolimus-related adverse events of all grades were mucositis (70%), maculopapular rash (51%), and nausea (43%). The most common, clinically important grade 3 or 4 adverse events were mucositis (9%), leukopenia (7%), hyperglycemia (7%), somnolence (6%), thrombocytopenia (5%), and depression (5%). Conclusion In heavily pretreated patients with locally advanced or metastatic breast cancer, 75 and 250 mg temsirolimus showed antitumor activity and 75 mg temsirolimus showed a generally tolerable safety profile.

Nurse practitioners play important roles in breast cancer prevention, early detection, therapeutic efficacy, and surveillance. Assessment of a patient's health status is part of the nine nurse practitioner core competencies updated in 2012 by the National Organization of Nurse Practitioner Faculties. Although adverse events are common in treatment for metastatic breast cancer (MBC), proactive management strategies can limit the number and/or severity of adverse events. Additionally, knowledge of common metastatic sites and clinical signs/symptoms of recurrence provides one of the first-line strategies for successful treatment. We review five case studies of women with MBC who were managed successfully with eribulin mesylate in late lines of therapy after at least two chemotherapeutic regimens for advanced breast cancer that included both an anthracycline and a taxane in either the adjuvant or metastatic setting.

Abstract Purpose: S-1 and cyclophosphamide (CPA) can be given orally, and their combination may have great potential for treating metastatic breast cancer (MBC). A phase I study of sequential S-1 and CPA therapy was conducted in patients with MBC; the recommended doses that were determined for this regimen were 80 mg/m 2 /day for S-1 and 100 mg/m 2 /day for CPA. We then conducted a phase II study of this oral S-1 and CPA regimen. Patients and Methods: This was a single-arm, open-label, single-center prospective phase II study to evaluate the efficacy of a sequential S-1 and CPA regimen for MBC. S-1 was administered orally 2´/day for 14 consecutive days, and then CPA was administered orally 1´/day for 14 consecutive days in a repeating 4-week cycle (S-1 for 2 weeks, CPA for 2 weeks). The primary endpoint was the overall response rate (ORR). Secondary endpoints included the overall survival (OS), progression-free survival (PFS), clinical benefit rate (CBR) and safety. Results: Thirty-six patients were enrolled in this study. The overall response was complete response in 0 (0%), partial response in 12 (33.3%), stable disease in 12 (33.3%), and progressive disease in 11 (30.1%) patients. The ORR was 33.3% (12/36). The CBR was 66.7% (24/36). The mean PFS was 9.5 months (95%CI: 7.1–11.9 months). The OS was 20.2 months (95%CI: 15.0–25.6 months) Grade 3/4 adverse events included neutropenia in seven patients (19.4%). Dose reductions because of adverse events occurred in 12 patients (33.3%). There was no treatment-related mortality. Conclusion: The combination of sequential therapy with S-1 and CPA was tolerable and had efficacy with good disease control. Sequential therapy with S-1 and CPA is a feasible new treatment option for patients with MBC.

Abstract Background:The effectiveness of antiangiogenic drugs in metastatic breast cancer(MBC) is still unclear. Apatinib is a small tyrosine kinase inhibitor that inhibits vascular endothelial growth factor receptor 2 (VEGFR-2). We performed this clinical trial to evaluate the efficacy and safety of apatinib and oral etoposide in patients with HER2-negative locally advanced or MBC.Methods:Patients with HER2-negative MBC previously treated with anthracycline and taxanes and failed ≥ 1 prior chemotherapy regimens were recruited. The starting dose of apatinib was 500 mg and 425 mg in patients with Eastern Cooperative Oncology Group (ECOG) scores of 0–1 and 2, respectively. The etoposide capsules were given at 50 mg/m2 on days 1 to 10 for 21 days. The primary end point was progression-free survival (PFS) which is assessed every 6 weeks (RECIST v1.1). Secondary end points included objective response rate (ORR), disease control rate (DCR), overall survival (OS), and safety.Results:Thirty-one eligible patients were enrolled. The median follow-up time was 11 months. The median PFS for all patients was 6.93 months (95% confidence interval (CI), 5.97–7.90), and 6.93 months(95% CI 5.27–8.60) and 6.56 months (95% CI 1.41–11.73) for patients with apatinib 425 mg and 500 mg once daily, respectively. The ORR was 35.5% (11/31). The DCR was 87.1% (27/31). The median OS was 20.37 months (95% CI, 11.39–29.34). The median PFS of patients who had hypertension and proteinuria was longer than that for those without hypertension and proteinuria. The most common grade 3/4 treatment-related adverse events(AE) were hypertension (12/31, 38.71%), fatigue (3/31, 9.68%), thrombocytopenia (3/31, 9.68%).Conclusion:Apatinib combined with etoposide capsules is effective and tolerable in heavily pretreated, metastatic HER2-negative breast cancer patients. A lower apatinib dose provide equivalent efficacy and reduced toxicity.
