Background: Low-dose metronomic chemotherapy (LDMC) is increasingly used in metastatic breast cancer (MBC). In this retrospective analysis, we examined the therapeutic effects and side effects of LDMC in a cohort of MBC patients. Methods: Patients with MBC were included when LDMC with oral cyclophosphamide (CTX) and methotrexate (MTX) was administered between 2009 and 2015. The primary endpoint was disease control rate (DCR) ≥ 24 weeks after the start of LDMC. Secondary endpoints were duration of progression-free survival (PFS), rates of discontinuation due to side effects, and DCR with regard to subgroups. Results: Retrospective data of 35 patients were available for this analysis. 31% patients achieved DCR. The median PFS was 12 weeks. 9% of patients discontinued LDMC due to adverse events. DCR was 37% in the first 2 lines and 25% in further lines of therapy. 22% of patients with multiple metastases and 35% with ≤2 different metastatic sites achieved DCR. DCR was achieved in 33% of hormone receptor(HR)-positive patients and 27% of HR-negative patients. Conclusion: The DCR of 31% is in line with the results of previous phase II studies. LDMC was well tolerated. Subgroup analysis was not able to identify a group in which LDMC was more efficient.

Abstract Background Treatment options for metastatic breast cancer (MBC) refractory to anthracyclines and taxanes are limited. In a phase III trial, eribulin demonstrated a significant improvement in overall survival compared to treatment of physician’s choice, but had limited tolerability because of neutropenia and peripheral neuropathy. Based on prior studies of alternative treatment schedules with other therapies, we hypothesized that a low-dose metronomic schedule of eribulin would permit patients to remain on treatment more consistently without treatment delays, resulting in longer time to progression, and improved toxicity profile. Methods We conducted a multi-site single arm, phase II trial patients with MBC. All patients were treated with metronomic eribulin (0.9 mg/m2 administered intravenously on days 1, 8, and 15 of a 28-day cycle.) Treatment was continued until the patient developed disease progression, unacceptable toxicity, or chose to stop the study. Patients must have had prior taxane exposure. The primary endpoint was progression-free survival. Secondary end points were overall survival, response rate, and clinical benefit rate. Exploratory biomarkers were performed to analyze change in levels of circulating endothelial cells (CECs), circulating endothelial precursors, and carbonic anhydrase IX (CAIX) with response to therapy. Findings We consented 86 patients and 59 were evaluable for final analysis. Median age was 59 years; 78% had HER2 negative tumors. The median progression-free survival (PFS) was 3.5 months with overall survival (OS) of 14.3 months. Objective response rate was 15% with clinical benefit rate of 48%. Reported grade 3 neutropenia and peripheral neuropathy were 18% and 5%, respectively. Treatment discontinuation due to toxicity was seen in 3% of patients. Interpretation Metronomic weekly low-dose eribulin is an active and tolerable regimen with significantly less myelosuppression, alopecia, and peripheral neuropathy than is seen with the approved dose and schedule, allowing longer duration of use and disease control, with similar outcomes compared to the standard dose regimen.

PURPOSE: To investigate the value of the addition of either cisplatin (CDDP) or lonidamine (LND) to epirubicin (EPI) in the first-line treatment of advanced breast cancer. PATIENTS AND METHODS: Three hundred seventy-one metastatic breast cancer patients with no prior systemic chemotherapy for advanced disease were randomized to receive either EPI alone (60 mg/m2 on days 1 and 2 every 21 days), EPI and CDDP (30 mg/m2 on days 1 and 2 every 21 days), EPI and LND (450 mg orally daily, given continuously), or EPI, CDDP, and LND. Time to progression, response rates, side effects, and survival were compared according to the 2 × 2 factorial design of this study. RESULTS: The groups were well balanced with respect to prognostic factors. Time to progression did not differ in the comparison between CDDP arms and non-CDDP arms (median, 10.9 months v 9.4 months, respectively; P = .10) or between that of LND arms and non-LND arms (median, 10.8 months v 9.9 months, respectively; P = .47), nor did overall survival. The response rate did not significantly differ in the comparison between LND arms and non-LND arms (62.9% v 54.0%, P = .08). No difference in treatment activity was observed between CDDP arms and non-CDDP arms. Toxicity was significantly higher in the CDDP arms, leading to CDDP dose adjustment in 40% of cases. The most frequent side effects were of a hematologic and gastrointestinal nature. The addition of LND produced more myalgias and fatigue. CONCLUSION: Neither CDDP nor LND was able to significantly improve the time to progression obtained by EPI. CDDP, however, significantly worsened the drug’s tolerability.

A randomized clinical trial was performed to determine if combination hormonal therapy with tamoxifen (TAM) and fluoxymesterone (FLU) was more efficacious than TAM alone for the treatment of postmenopausal women with metastatic breast cancer. Patients failing TAM could subsequently receive FLU. The dose of both drugs was 10 mg orally twice daily. Objective responses were seen in 50 of 119 TAM patients (42%) and 63 of 119 TAM plus FLU patients (53%) (one-sided P = .05). Time to disease progression distributions were better for TAM plus FLU (median, 350 days v 199 days), but the log rank test only approached statistical significance (one-sided P = .07). Duration of response and survival distributions were similar between the two treatment arms. Toxicities, in terms of androgenic side effects, were greater on the TAM plus FLU regimen. Fifty-two patients are evaluable for response with FLU following TAM and 21 (40%) have achieved a response. We conclude that the advantages in terms of response rate and time to progression observed with TAM plus FLU probably represent a biological effect, but are not of sufficient magnitude to justify the routine clinical use of this combination given the lack of survival advantage and side effects encountered.

Bivalent Metal Ions

1085 Background: Platinum-based agents are important components of therapy of metastatic breast cancer (MBC) and triple negative breast cancer. Their use can be limited by development of resistance. Metallothioneins (MT) are low molecular weight proteins believed to bind bivalent metal ions such as platinum and zinc. MT expression has been associated with decreased survival in breast cancer patients. A proposed mechanism confers resistance to platinum-based agents by their inactivation or limitation of their activity by MT binding. Methods: MT expression in 99 women with MBC (selected at random from our database of 800 women with MBC) was determined from primary breast cancer tissue (n=80) or metastatic tissue n=19). MT expression was determined by immunohistochemistry, and graded as negative, weak, moderate or strong. Clinical data was obtained through our database and supplemented by chart review. Overall survival from breast cancer diagnosis (OS), progression free survival for first metastastic regimen (PFS), and time from first metastasis to death or last update (metastatic survival, MS), were calculated through December 2011 using the log rank test. Results: Consistent with prior studies, moderate to strong MT expression was associated with decreased 5-year OS (p=.03). There was no correlation between MT expression and PFS or MS in this cohort. Surprisingly, MT expression at any degree was strongly associated with better MS in patients with MBC that received carboplatin-based regimens in the first line (n=25, p=.0005) or at any line (n=41, p=.0437). Conclusions: Consistent with prior studies, MT expression was associated with decreased survival in patients with MBC. Surprisingly, MT expression was associated with longer MS in patients with MBC that received carboplatin. These findings are inconsistent with the hypothesis that MT expression causes chemoresistance to platinum based agents in patients with metastatic breast cancer. Further studies are needed to elucidate the mechanisms behind these findings.
