TPS1117 Background: This is a randomized Phase II/III trial to evaluate if stereotactic body radiotherapy (SBRT) and/or surgical resection (SR) of all metastatic sites in newly oligo-metastatic breast cancer who have received up to 12 months of first line systemic therapy without progression will significantly improve median progression free survival (PFS). If this aim is met the trial continues as a phase III to evaluate if SBRT/SR improves 5 year overall survival. Secondary aims include local control in the metastatic site, new distant metastatic rate, and technical quality. Translational primary endpoint is to determine whether < 5 CTCs is an independent prognostic marker for improved PFS and OS. Methods: Women with pathologically confirmed metastatic breast cancer to ≤ 4 sites who have been diagnosed within 365 days with metastatic disease and the primary tumor site disease is controlled. CNS metastases are ineligible. ER/PR and HER-2 neu status is required. Site radiation credentialing with a facility questionnaire and pre-treatment review of first case is required. Randomization is to standard systemic therapy with local radiotherapy/ surgery for palliation when necessary versus ablative therapy of all metastases with SBRT and/or SR. For the phase IIR portion to detect a signal for improved median PFS from 10.5 months to 19 months with 95% power and a 1-sided alpha of 0.15 and accounting for ineligible/lost patients, 128 patients will be required. For the Phase III, an additional 232 patients will be required to definitively determine if ablative therapy improves 5-year overall survival from 28% to 42.5% (HR=0.67), with 85% power and a one-sided type I error of 0.025. For the translational research assuming a two-sided probability of type I error of 0.05, the number of patients accrued in the Phase II-R and Phase III portions will provide sufficient power of at least 91% and 93% to detect whether < 5 CTC’s is prognostic for PFS and OS, respectively. Present accrual (1-31-2019): 105. Contact Information: Protocol: CTSU member web site https://www.ctsu.org . Enrollment: OPEN at https://open.ctsu.org . Support: This project is supported by NRG Oncology grants U10CA180868 and U10CA180822 from the National Cancer Institute (NCI).

Eribulin Mesylate

TPS1140 Background: Eribulin mesylate is a nontaxane microtubule dynamics inhibitor that is approved in patients with metastatic breast cancer who have previously received at least two chemotherapeutic regimens (including an anthracycline and a taxane) for metastatic breast cancer. In a previous phase III study, eribulin mesylate demonstrated to significant improvement in overall survival in patients with heavily pretreated, locally recurrent or metastatic breast cancer when compared to treatment of physician’s choice. The majority of patients were HER2-negative and all had previously failed 2 or more regimens. Overall, the tolerability and positive phase III findings in this patient population suggest eribulin mesylate may provide a treatment advantage when given earlier in the course of therapy for HER2-negative, metastatic breast cancer. Methods: This study is phase II, multicenter, open-label, single-arm in patients with HER2-negative metastatic breast cancer who have been treated with chemotherapeutic regimens including an antheracycline and a taxane. Eribulin mesylate (1.4mg/m2) will be given on days 1 and 8 of each 21-day cycle. The primary endpoint is objective response rate, and secondary endpoints include duration of response, progression-free survival, overall survival, the safety of the treatment, and quality of life. Eligibility Criteria: Patients must have confirmed HER2-negative metastatic breast cancer with at least 4 weeks since prior neoadjuvant or adjuvant chemotherapy, and have not received over 2 chemotherapeutic regimens for metastatic disease. Additional eligibility criteria include adequate performance status (ECOG PS:0-2) and end organ/marrow function, and ejection fraction > 50%. Accrual: This study began in December 2012. The expected end of accrual of 35 patients will be the last quarter 2015.

Introduction: In advanced breast cancer, local treatment is considered palliative. However, although there are some polemic opinions about the surgical treatment, some of the latest studies have emphasized that in advanced cases primary tumor resection (PTR) is related to better outcomes. This review aims to evaluate how resection of the original tumor impacts women with metastatic breast cancer, considering the most recent studies about this subject. Methods: The search was performed in MEDLINE, Scopus, PMC, Current Contents and Wiley Online Library databases; 23 articles - from 2016 to 2019 - were selected and 11 were included in this review. As inclusion criteria were considered: studies presenting outcomes about resection of the primary tumor, comparison between chemotherapy/ hormone therapy/ targeted cancer therapies and surgical intervention, studies published from 2016 to 2019 and available in English, Spanish or Portuguese. We excluded those which did not approach PTR, did not present outcomes of interest (progression-free survival comparison between PTR and systemic therapy) or only discussed systemic therapy, as well as those published before 2016. Results: It was reported in 6 studies that progression-free survival is better on those who underwent surgery. PTR was also related to longer median overall survival in women submitted to surgery, up to 16 months higher when compared to the ones who were not. Enhanced survival even pertained to surgical groups regardless of tumor size.  Conclusion: Based in the analysis, PTR in metastatic breast cancer can be related to higher overall survival.

PURPOSE: The purpose of this multi-institutional phase II trial was to evaluate the efficacy and toxicity of doxorubicin and docetaxel plus granulocyte colony-stimulating factor (G-CSF) in patients with metastatic breast cancer. The primary objective was to determine whether the combination produced a response rate of at least 50%. PATIENTS AND METHODS: Fifty-four patients with metastatic breast cancer received doxorubicin (60 mg/m2 by intravenous [IV] injection) followed 1 hour later by docetaxel (60 mg/m2 by IV infusion over 1 hour) every 3 weeks for up to eight cycles. All patients also received G-CSF. RESULTS: Objective response occurred in 29 (57%) of 51 eligible patients (95% confidence interval [CI], 42% to 70%), including three patients who had a complete response (6%; 95% CI, 1% to 16%). The median response duration was 7 months (95% CI, 6.0 to 15.0 months), median time to treatment failure was 7.6 months (95% CI, 6.2 to 9.9 months), and the median survival was 27.5 months (95% CI, 21.5 months to upper limit not reached). The median cumulative doxorubicin dose was 395 mg/m2 (range, 60 to 480 mg/m2). Fifteen patients (28%) were documented to have a decrease in the left ventricular ejection fraction below normal, and three patients (6%; 95% CI, 1% to 15%) developed congestive heart failure. CONCLUSION: Using criteria that we had defined a priori, the doxorubicin-docetaxel regimen as used in this study was sufficiently active and tolerable to justify a phase III comparison with doxorubicin-cyclophosphamide in early-stage breast cancer.

PURPOSE: This phase III trial compared the efficacy and safety of doxorubicin and paclitaxel (AT) to 5-fluorouracil, doxorubicin, and cyclophosphamide (FAC) as first-line therapy for women with metastatic breast cancer. PATIENTS AND METHODS: A total of 267 women with metastatic breast cancer were randomized to receive either AT (doxorubicin 50 mg/m2 followed 24 hours later by paclitaxel 220 mg/m2) or FAC (5-fluorouracil 500 mg/m2, doxorubicin 50 mg/m2, cyclophosphamide 500 mg/m2), each administered every 3 weeks for up to eight cycles. Patients had to have measurable disease and an Eastern Cooperative Oncology Group performance status of 0 to 2. Only one prior non–anthracycline, nontaxane-containing adjuvant chemotherapy regimen was allowed. RESULTS: Overall response rates for patients randomized to AT and FAC were 68% and 55%, respectively (P = .032). Median time to progression and overall survival were significantly longer for AT compared with FAC (time to progression 8.3 months v 6.2 months [P = .034]; overall survival 23.3 months v 18.3 months [P = .013]). Therapy was generally well-tolerated (median of eight cycles delivered in each arm). Grade 3 or 4 neutropenia was more common with AT than with FAC (89% v 65%; P < .001); however, the incidence of fever and infection was low. Grade 3 or 4 arthralgia and myalgia, peripheral neuropathy, and diarrhea were more common with AT, whereas nausea and vomiting were more common with FAC. The incidence of cardiotoxicity was low in both arms. CONCLUSION: AT conferred a significant advantage in response rate, time to progression, and overall survival compared with FAC. Treatment was well-tolerated with no unexpected toxicities.

1087 Background: Paclitaxel/carboplatin combinations are highly active in metastatic breast cancer (MBC). We conducted a randomized, phase III, non-inferiority trial comparing paclitaxel/carboplatin (TP) with paclitaxel/epirubicin (TE) as first-line therapy for MBC. Progression-free survival (PFS) was the primary efficacy endpoint. Secondary endpoints included response rate, overall survival, tolerability, and quality of life (QoL). Methods: From June 2009 to January 2015, 231 patients were randomly assigned, 115 of whom were randomized to TP and 116 to TE. Baseline characteristics were relatively well-balanced in the two treatments. Results: After a median follow-up of 29 months, no significant difference was observed between the two treatments in objective response rate (ORR) (38.3% vs. 39.7%, respectively). Both the progression-free survival (p=0.158) and overall survival (p=0.369) were very similar between the two treatments. Both regimens were well tolerated. The main toxicities were myelosuppression, gastrointestinal reactions, and alopecia. TP showed higher grades 3–4 alopecia and higher nausea (p<0.05). TE showed higher incidence of myelosuppression than TP (p<0.05) (Table). Those patients whose epirubicin cumulative dose was more than 1000 mg/m2 did not suffer worse cardiotoxicity. Conclusions: Our study suggests that TP arm is an effective therapeutic alternative for patients with MBC, especially in those previously exposed to epirubicin in the adjuvant setting. TP has some advantages, such as less cost and less side effects (myelosuppression and fatigue). Clinical trial information: NCT02207361. [Table: see text]

1085 Background: Extracellular matrix (ECM) is the non-cellular component of all tissues. Increased ECM formation and matrix metallo-protease (MMP) mediated ECM degradation are parts of tumorgenesis. The altered ECM remodeling generates specific ECM fragments that are released into the circulation. We evaluated the association of specific ECM/collagen fragments measured in serum with outcomes in two independent metastatic breast cancer (MBC) cohorts. Methods: C1M (MMP-degraded type I collagen), C3M (MMP-degraded type III collagen), C4M (MMP-degraded type IV collagen), and PRO-C3 (pro-peptide reflecting truetype III collagen formation) were measured by ELISA in pre-treatment serum from a phase III randomized clinical trial of 2nd-line hormone therapy (HR+, n= 153), and a 1st-line trastuzumab-treated cohort (HER2+, n=64). In both cohorts, all sites of metastases were included. The collagen-fragments were evaluated on continuous and categorical (75th percentile cut-off) bases by univariate Cox-regression analysis for their association with time-to-progression (TTP) and overall survival (OS). Results: In the HR+ cohort, Pro-C3 measured as a continuous variable was significantly associated with TTP; C1M, C4M and Pro-C3 were associated with OS. On a categorical basis, C1M and C3M were associated with TTP; all fragments were associated with OS (Table). In the HER2+ cohort, continuous measurements of all fragments were associated with TTP and OS. On a categorical basis (Table), all fragments were associated with TTP; C4M and Pro-C3 were associated with OS. Conclusions: ECM remodeling quantified in pre-treatment serum was associated with shorter TTP and OS in two independent MBC cohorts receiving systemic therapy. If validated, quantification of ECM remodeling in serum has potential as prognostic and/or predictive biomarkers in MBC. [Table: see text]

PURPOSE: This multicenter phase II trial investigated the efficacy and toxicity of a combination of the novel intracellular histamine antagonist, N,N-diethyl-2-[4-(phenylmethyl)phenoxy]ethanamine.HCl (DPPE), and doxorubicin in patients with anthracycline-naïve metastatic breast cancer. Preclinical models and early single institutional studies suggested DPPE could potentiate the cytotoxicity of doxorubicin. PATIENTS AND METHODS: Forty-two women, 32 to 77 years old (median, 59 years), with anthracycline-naïve metastatic breast cancer were treated. Patients may have had one previous regimen of nonanthracycline chemotherapy, either in the adjuvant or metastatic disease treatment setting. DPPE (6 mg/kg) was administered as an 80 minute intravenous infusion with doxorubicin (60 mg/m2) given intravenously over the last 20 minutes of the DPPE infusion. Patients were premedicated with an antiemetic and sedating regimen. The DPPE/doxorubicin treatment was given every 21 days for a maximum of seven cycles. RESULTS: All 42 patients were assessable. Overall, toxicity was comparable to that expected with doxorubicin alone, with the exception of DPPE-related motion sickness, mild hallucinations, and cerebellar signs at the time of the infusion. These CNS side effects were manageable in an ambulatory care setting, improved with subsequent cycles of treatment, and did not usually require hospitalization. Four patients developed febrile neutropenia. Thirty-five patients received four or more cycles of chemotherapy. The overall response rate was 52.5% (95% confidence interval, 36% to 68%), with 9.5% complete responses (n = 4), 43% partial responses (n = 18), and 38% of patients with stable disease (n = 16). CONCLUSION: The antitumour effects of DPPE/doxorubicin the 52.5% response rate seems encouraging, particularly in consideration of the fact that a recently reported randomized National Cancer Institute of Canada Clinical Trials Group trial using single-agent doxorubicin 60 mg/m2 in one of the treatment arms achieved a 31% response rate. Thus, a randomized phase III trial of doxorubicin versus doxorubicin plus DPPE is being conducted in this clinical setting.
