Taxanes have been shown to be the most effective treatment for recurrent or metastatic breast cancer. However, for patients pretreated with taxanes, more active and possibly less toxic drugs are needed. In this retrospective study, we investigated on the effectiveness and safety of eribulin mesylate in 91 taxane-refractory subjects, extracted from the ESEMPIO database, which included 497 metastatic breast cancer patients treated with eribulin allover the Italy. This analysis included only those patients who have shown disease progression while receiving taxane therapy (primary refractory), or those who achieved a response followed by progression while still on therapy (taxane failure). Overall, 41/91 patients (45.2%) showed a clinical benefit; 1 complete response (2.2%) and 16 partial responses (17.6%) were observed. The median progression free survival was 3.1 months (95% CI: 2.8–3.5) and the median overall survival was 11.6 months (95% CI: 8.7–16.7). With regard to toxicity, 53 patients (58%) experienced asthenia/fatigue, 23 (25%) showed peripheral neurotoxicity, 18 (20%) alopecia, 12 (13%) mild constipation and 27 (30%) neutropenia. The toxicity related to the treatment led to eribulin dose reduction in 19 (21%) and discontinuation in 9 (10%) patients, respectively. In conclusion, this study suggests that eribulin is effective and well tolerated also in taxane-refractory patient.

Purpose To determine whether the addition of intravenous (IV) vinorelbine to epirubicin increased the progression-free survival in first-line treatment of metastatic breast cancer. Patients and Methods A total of 387 patients were randomly assigned to receive IV epirubicin 90 mg/m2 on day 1 and vinorelbine 25 mg/m2 on days 1 and 8, or epirubicin 90 mg/m2 IV on day 1. Both regimens were given every 3 weeks for a maximum of 1 year but discontinued prematurely in the event of progressive disease or severe toxicity. In addition, epirubicin was discontinued at a cumulative dose of 1,000 mg/m2 (950 mg/m2 from June 1999). Prior anthracycline-based adjuvant chemotherapy and prior chemotherapy for metastatic breast cancer was not allowed. Reported results were all based on intent-to-treat analyses. Results Overall response rates to vinorelbine and epirubicin, and epirubicin alone, were 50% and 42%, respectively (P = .15). The complete response rate was significantly superior in the combination arm (17% v 10%; P = .048) as was median duration of progression-free survival (10.1 months v 8.2 months; P = .019). Median survival was similar in the two arms (19.1 months v 18.0 months; P = .50). Leukopenia related complications, stomatitis, and peripheral neuropathy were more common in the combination arm. The incidences of cardiotoxicity and constipation were similar in both arms. Conclusion Addition of vinorelbine to epirubicin conferred a significant advantage in terms of complete response rate and progression-free survival, but not in terms of survival.

Aim: To examine the effectiveness of eribulin mesylate for metastatic breast cancer post cyclin-dependent kinase inhibitor (CDKi) 4/6 therapy. Materials & methods: US community oncologists reviewed charts of patients who had received eriublin from 3 February 2015 to 31 December 2017 after prior CDKi 4/6 therapy and detailed their clinical/treatment history, clinical outcomes (lesion measurements, progression, death) and toxicity. Results: Four patient cohorts were created according to eribulin line of therapy: second line, third line, per US label and fourth line with objective response rates/clinical benefit rates of 42.2%/58.7%, 26.1%/42.3%, 26.7%/54.1% and 17.9%/46.4%, respectively. Median progression-free survival/6-month progression-free survival (79.5% of all patients censored) by cohort was: 9.7 months/77.3%, 10.3 months/71.3%, not reached/70.4% and 4.0 months/0.0%, respectively. Overall occurrence of neutropenia = 23.5%, febrile neutropenia = 1.3%, peripheral neuropathy = 10.1% and diarrhea = 11.1%. Conclusion: Clinical outcome and adverse event rates were similar to those in clinical trials and other observational studies. Longer follow-up is required to confirm these findings.

Background: Eribulin mesylate is a non-taxane microtubule inhibitor which can be used after anthracycline and taxane treatment in patients with metastatic breast cancer (MBC). The purpose of this study was to investigate the efficacy and safety of eribulin monotherapy in heavily pretreated patients with MBC. Methods: In this study, a total of 45 eligible patients with MBC who received eribulin in HCG Cancer Speciality Center from November 2014 to March 2016 were prospectively analyzed. Breslow (generalized Wilcoxon) survival analysis was carried out for progression-free survival and for overall survival. Patients were excluded if they had not taken treatment for 3 cycles and defaulted/expired during the treatment. Results: In this study, median age of patients was 52 years. A total of 27 (60%) patients had estrogen receptor and progesterone receptor (PR) positive primary tumors, whereas HER2 was overexpressed or amplified in 7 (15.6%); a triple negative subtype was recorded in 13 patients (28.9%). Regarding toxicity, 30 patients (66.67%) tolerated treatment well and 3 patients (6.67%) got anemia, 6 patients (13.3%) experienced neutropenia, and 7 (15.62%) patients had neurological toxicity. About 14 (31.1%) patients showed PR, 12 (26.7%) patients had stable disease (SD), whereas 19 (42.25%) patients showed progression disease (PD). Response evaluation at 6 cycles was possible in 18 patients and revealed that 4 (22.5%) patients showed PR, 10 (55.5%) patients had SD, whereas 4 (22.2%) patients had PD. Progression-free survival of the overall study population was 3.95 months. Conclusions: Eribulin mesylate is efficacious and tolerable chemotherapy as second- and third-line treatment options for MBC.

Eribulin Mesylate

Introduction: Breast cancer is the most common cancer, majority of patients present in advanced stage and 30% develop distant metastasis. Metastatic Breast Cancer (MBC) is not curable and treatment aims at prolongation of life with good palliation. There is no standard treatment, though the usual first and second lines of chemotherapy include anthracyclines and taxanes. The third line chemo drugs available are gemcitabine, capecitabine, vinorelbine and eribulinmesylate Materials and Methods: This is a retrospective study of MBC patients pretreated with anthracyclines and taxanes and then received 4 cycles of eribulin during the period March 2015-2017 in Medical College, Alappuzha and aims at studying the tumor response and drug toxicities. The tumor response is studied using CR-complete response, PR- partial response, PD-progressive disease and SD-stable disease. Results: There were a total of 18 patients, majority of whom were below 50 years. ECOG performance status of 0-1 was found in 83.3% and 77.8% were receptor positive. No patient had CR, 66.7% of patients had PR, 22.2% had PD and 11.1% had SD. 61.1% of patients who had a PR had good performance status.55.6% of patients who were ERPR positive had a PR and 44.4% patients who were Her2neu positive had a PR. Most common toxicities detected were alopecia (83.3%), neutropenia (72.2%), fatigue (72.2%) and neurotoxicity (55.6%). Conclusion: Eribulin mesylate is a drug having good response with tolerable toxicities and can be considered in our population. Keywords: Metastatic breast cancer, eribulin mesylate, capecitabine.

37 Background: Metastasis is the main course of death in breast cancer (BC) patients. Reliable prognostic markers are very much appreciated to evaluate possible outcome of patients. Circulating tumor cells (CTC) is a circulating prognostic tumor marker of metastatic breast cancer patients. Despite the big technical challenges in CTC detection, the reliability of CTC enumeration for the prognosis of BC is still on debate. Some studies have proved that the plasma level of X, a major component in extracellular matrix, was increased in patients with metastatic breast cancer. However, the association between the plasma X level and the prognosis of metastatic breast cancer is still unknown. Methods: Plasma X was measured by ELISA in 60 healthy controls, 48 primary breast cancer (PBC) patients, and 212 metastatic breast cancer (MBC) patients. Progression free survival (PFS) and overall survival (OS) were analyzed. An independent cohort with 210 primary and 69 patients with metastatic breast cancer were further investigated to validate our findings. Results: A 2-fold elevation was presented in MBC patients when compared with PBC patients and controls, regardless of their CTC status. A multivariate Cox regression demonstrated that lower X level at base line was associated with longer PFS (HR: 2.50, 95% CI: 1.72–3.63, p = 1.607 × 10-6), as well as longer OS (HR: 3.74, 95% CI: 1.65 – 8.51, p = 0.002). After 1stcycle of chemotherapy, plasma X level was still prognostic and was dramatically decreased in patients who had responded to the treatment (54%, IQR: 36%–64%). In the independent validation round, a 2-fold increase of plasma X was observed again in MBC patients, compared with PBC patients. The prognostic value was also validated for PFS (HR: 2.12, 95% CI: 1.43– 3.84, p = 0.001) and OS (HR: 2.91, 95% CI: 1.73–7.65, p = 0.002) in MBC patients. Conclusions: Plasma X could be used as a diagnostic and prognostic marker for metastatic breast cancer. Its reduction after 1st cycle of chemotherapy could be an indicator of treatment efficacy. This finding may further prevent unnecessary systemic therapy by facilitating personalized medicine in the treatment of metastatic breast cancer.

Background: This phase II study was conducted to evaluate the efficacy and safety of the chemotherapy combination of gemcitabine and vinorelbine in taxane-pretreated Japanese metastatic breast cancer patients. Methods: In this multicenter, phase II, single-arm study, patients with recurrent or metastatic HER2-negative breast cancer were administered gemcitabine (1,200 mg/m2) and vinorelbine (25 mg/m2) intravenously on days 1 and 8 every 3 weeks. The primary endpoint was the objective response rate, and other endpoints included progression-free survival, overall survival, and safety. Results: A total of 42 patients were enrolled in this study. The objective response rate and clinical benefit rate were 24 and 43%, respectively. The median progression-free survival was 4.0 months. The median overall survival was 11.1 months. Grade 3/4 neutropenia was the most common hematologic toxicity, occurring in 22 patients (54%). Nonhematologic toxicity was moderate and transient, with fatigue (48%) being the most common condition and no severe adverse event reported. Conclusion: The combination of gemcitabine and vinorelbine is an effective and tolerable regimen for HER2-negative, taxane-pretreated, metastatic breast cancer patients in Japan.

1070 Background: Aromatase inhibitors represent a novel hormonal therapy for breast cancer. Aromatase is expressed in the ovaries, brain, bone and, adipose and breast tissue. Elevated WHR, representing a higher abdominal fat distribution, has been associated with both the development of and mortality from breast cancer. Therefore, we aimed to identify whether abdominal fat distribution could affect the outcome in metastatic breast cancer patients treated with AIs. Methods: A total of 46 metastatic breast cancer patients treated with first line hormonal therapy were enrolled in this study. Pretreatment body weight, height, BMI and WHR were measured. Estrogen, progesteron and c- erb-B2 receptor status were also evaluated in analyses. Univariate and multivariate Cox regression analyses, and Kaplan Meier survival curves subjected to log rank testing were utilized for the survival analyses. Forward likelihood ratio was used for the multivariate selection process. A P value < 0.05 was considered to be significant. Results: Median age was 51 years (range 28 - 75). 36 patients were treated with letrozole and 10 patients with anastrozole. Median body weight, height, WHR and BMI were found to be 68.5 kg (range 46 - 115), 156 cm (range 137 - 167), 0.91 (range 0.7 - 1.2), and 28.7 (range 18 - 45), respectively. Factors associated with overall survival in the univariate analysis were age, c-erb-B2 expression intensity (+++ versus others by immunohistochemistry), and WHR, whereas only WHR retained significance in the multivariate analysis. Likewise, predictors of progression free survival were c-erb-B2 expression intensity and WHR. However, none of these factors was significant in the multivariate analysis. Median overall survival figures were 472 days versus unreached for patients with a WHR of <0.92 and =0.92 (Log rank statistic = 9.76, P = 0.002). Similarly, the corresponding progression free survival figures for patients with a WHR of <0.92 and =0.92 were 423 versus 1,004 days (Log rank statistic = 6.37, P = 0.012). Conclusions: This is the first report examining and suggesting the value of abdominal fat distribution in relation with benefit from AIs in metastatic breast cancer. Our results should be validated in larger series. No significant financial relationships to disclose.
