6552 Background: Although new chemotherapy agents have been approved during the past decade for the treatment of metastatic breast cancer (MBC), it is unclear whether their use has changed the outcome of patients. This study assessed the clinical and economic impacts of these drugs. Methods: We undertook a retrospective study of women diagnosed with MBC during two periods of time, 1994–1998 and 2003–2006 and compared overall survival data between the two groups. Female patients with MBC were identified from the Centre Léon Bérard (Lyon, France) database. Tumor and treatment characteristics, costs of chemotherapy, and patient outcome were compared using the X2 test, the log rank test, and Cox regression analysis. Overall survival was calculated from the date of MBC diagnosis to the date of death or last follow-up. Chemotherapy-related costs were calculated according to the 2008 pricelist of French cancer centers. Results: A total of 301 MBC cases were identified. The median follow-up of living patients was 3.87 years. No survival difference was observed between the two periods, with a median overall survival of 2.76 years for the 1994–1998 cohort (149 patients) and 2.68 years for the 2003–2006 cohort (152 patients) (HR 1.04, 95%CI 0.70–1.55; p = 0.83). The median number of lines of chemotherapy was similar in the two groups (=3). The median cost of chemotherapy per MBC patient was 3 times higher in 2003–2006 (25,320 €) than in 1994–1998 (8,865 €; p < 0.001). In multivariate analysis, prognostic factors for overall survival were the number of metastatic sites (HR 2.06; p < 0.0001), bone metastases (HR 0.67; p = 0.007), and hormone receptors (HR 0.56; p = 0.002). Survival was identical in HER-2 positive and HER-2 negative patients (HR 0.99; p = 0.99). Conclusions: Despite the implementation of numerous novel chemotherapeutic agents, the overall survival of patients with metastatic breast cancer has not improved over the last decade on the scale of our institution, whereas the costs of chemotherapy have significantly increased. No significant financial relationships to disclose.

BackgroundAnticancer drugs can interact with the tumour microenvironment and their effects could be exploited to favour anticancer immune response. Eribulin contributes to tumour vasculature remodelling and transforming growth factor β (TGF-β) modulation in experimental models and in humans. We performed a prospective, translational, exploratory analysis of the levels of circulating cytokines at different time points in patients with metastatic breast cancer treated with eribulin.MethodsTGF-β, tumour necrosis factor α, vascular endothelial growth factor, IL-6, IL-8, IL-10, IL-21 and C-C motif chemokine ligand-2 levels were assessed in peripheral blood samples obtained from seven healthy volunteers and 41 patients at baseline (T0), after four cycles of eribulin (T1) and at disease progression (TPD). Baseline values and longitudinal changes in cytokine levels were then related to clinical outcome.ResultsIn the 41 patients, high IL-6 and IL-8 (above the median) at T0 significantly correlated with worse survival. At T1, IL-21 significantly decreased in patients with TPD within the fourth course of treatment, compared with patients without progression. TGF-β and IL-8 above the median and IL-21 below the median at T1 significantly correlates with worse progression free survival (PFS). Patients exhibiting an increase of TGF-β or a decline of IL-21 between T0 and T1 showed a significantly worse PFS. Multivariate Cox regression analysis showed that only plasma TGF-β changes at T1 correlated with survival. At TPD, TGF-β significantly increased in all patients.ConclusionsWe observed a significant correlation between TGF-β decline during eribulin treatment and outcome in patients with metastatic breast cancer. Altogether, our data suggest that eribulin treatment might interfere with the tumour microenvironment.

TPS1122 Background: Breast cancer (BC) represents 25% of all cancers in women. Whilst the majority have early stage disease approximately 30% will develop metastatic breast cancer (MBC). In HER2 negative MBC, palliative chemotherapy is one of the main treatment options. It remains to be seen whether the use of adjuvant taxane chemotherapy leads to an increase in taxane resistance at the onset of MBC, although for patients with a relatively short disease free interval this may be the case. Cabazitaxel (CBZ) is a novel taxoid selected for development from preclinical evidence in cell lines resistant to docetaxel and paclitaxel including activity in a HER-2 positive BC tumour xenograft, with innate resistance to docetaxel. Clinically CBZ is licensed for metastatic castration-resistant prostate cancer following progression during or after docetaxel chemotherapy. A phase 3 RCT in this patient group showed a 3 month overall survival benefit for patients receiving CBZ and prednisolone compared with mitoxantrone and prednisolone. Methods: CONCEPT is an open label randomised phase 2 trial of first line chemotherapy in patients with HER-2 negative MBC where paclitaxel would be considered the standard treatment. Patients are randomised to cabazitaxel 25 mg/m2 every 21 days for 6 cycles or paclitaxel 80 mg/m2 weekly for 18 weeks. Eligibility includes patients who are PS 0 or 1 who may have received prior docetaxel in the adjuvant setting or be taxane-naïve. The primary endpoint is progression free survival (PFS), defined as the time between the date of randomisation and progression (according to RECIST version 1.1) or death from any cause. Secondary end-points include safety, overall survival and assessment of quality of life factors by FACT-B and EQ-5D-5L. For the current phase 2 study 90 patients will be recruited, with a 1:1 randomisation, proceeding to phase 3 of 160 patients, if the interim analysis does not show futility. To date 38 patients have been recruited from 10 centres. The IDMC met in Oct 2016 and recommended the study continue recruitment.

Abstract   BACKGROUND: There are different data in the literature about the consequences of the development of metastasis as de novo or recurrent. In this study, we retrospectively investigated the clinicopathologic and prognostic characteristics of HER-2 positive de novo and recurrent metastatic breast cancer (MBC) patients. PATIENTS AND METHODS: The data of patients admitted to our clinic between 1996-2017 were analyzed retrospectively. The baseline features, treatments and survival data were recorded. Recurrent metastatic patients were further categorized as disease free interval (DFI) <24 months and DFI >24 months. The features of two groups were analyzed by pearson chi-square test. Survival were calculated by using the Kaplan-Meier method with the Long-rank test. p <0.05 was considered statistically significant. RESULTS: A total of 44 patients were included to study in which 20 patients in de novo HER-2 positive MBC group and 24 patients in recurrent HER-2 MBC group. There was no difference in baseline features between groups. The median OS in de novo and recurrent MBC group was 60.3 months and 43.9 months respectively (HR: 0.87, 95% CI 0.37-2.05, p=0.76). OS was not different between de novo MBC group and patients with DFI <24 months and with DFI > 24 months (p=0.135). CONCLUSION: Our study showed that baseline features of patients with de novo HER-2 positive MBC and recurrent HER-2 positive MBC did not differ from each other. The presence of metastasis at the time of diagnosis or during follow-up did not change response to treatments.

The significance of androgen receptor (AR) in metastatic breast cancer (MBC) remains unclear, and it is still largely unknown how AR expression level influences HER2-positive tumors. This study aimed to investigate the prognostic and predictive value of AR in HER2-enriched MBC. Primary and/or paired metastatic tumors of 304 patients with pathologically confirmed HER2-enriched MBC were collected and immunohistochemically assessed for AR expression. The associations of AR and other clinicopathological characteristics were compared using the Chi-square test. Progression-free survival (PFS) and overall survival (OS) were calculated using the Kaplan–Meier method and log-rank test. Cox regression analysis was used to determine independent prognostic factors. AR-positivity with a cut-off value of 10% was observed in 237 (78.0%) cases and was associated with longer PFS, 13.2 months, as compared to that of 8.2 months (P = 0.004) in patients with AR-negativity. Moreover, a significant increase in the 5-year OS rate (65.3% vs 36.2%, P < 0.001) was also observed for patients with AR-positive tumors. Cox regression analysis identified AR-positivity as an independent prognostic factor of both PFS (hazard ratio = 0.71, P = 0.039) and OS (HR = 0.53, P = 0.013). Additionally, for those who received first-line Trastuzumab therapies, prolonged PFS (15.8 months vs 8.2 months, P = 0.005) and 5-year OS rate (66.2% vs 26.2%, P = 0.009) were observed in AR-positive tumors compared to AR-negative ones. In conclusion, AR was identified as an independent prognostic factor for favorable PFS and OS and could also predict the efficacy of first-line Trastuzumab treatment in patients with HER2-enriched MBC.

We aimed to evaluate the co-expression of PD-L1 and epithelial-mesenchymal markers in CTCs from metastatic breast cancer (MBC) patients and to determine if there is any relationship with patients’ outcome after eribulin treatment. Using cytospin preparations of peripheral blood mononuclear cells (PBMCs) from MBC patients treated with eribulin and a combination of immunocytochemistry and immunofluorescence, we quantified PD-L1, keratins and vimentin in single and cluster CTCs on days 1 and 8 of the first-treatment cycle. CTCs (n = 173) were found in 31 out of 38 patients. At baseline, the presence of cluster CTCs (p = 0.048), cluster mesenchymal CTCs (mCTCs) (p = 0.0003) or cluster PD-L1+mCTCs (p = 0.006) was associated with shorter overall survival (OS). In multivariate cox regression analysis, the detection of cluster mCTCs was the only parameter associated with increased risk of death (p = 0.024). On day 8 post-eribulin administration, PD-L1+mCTCs and especially single PD-L1+mCTCs decreased in 75% and 89% of patients, respectively. The detection of single PD-L1+mCTCs after eribulin treatment was correlated with shorter PFS (p = 0.047) and OS (p = 0.020). In conclusion, our study identified for the first time that cluster and single PD-L1+mCTCs subpopulations are of clinical significance in patients with MBC and highlighted the importance of CTC phenotyping during treatment with eribulin.

11110 Background: Despite patient selection based upon detection of Her-2/neu overexpression by immunohistochemistry (IHC) and/or presence of amplification of the Her-2/neu-encoding erbB2 oncogene measured by FISH, response to trastuzumab-based therapy is only achieved in a subset of patients with Her-2/neu overexpressing breast carcinomas. Exact quantification of erbB2 copy-number relative to chromosome 17 (CEP17) (ErbB2/CEP17 ratio “R”) probably adds further important predictive information. Methods: Clinical data of 137 patients receiving trastuzumab based treatment for Her-2/neu overexpressing (IHC) metastatic breast cancer were analysed. ErbB2/CEP17 ratio (R) was determined by quantitative FISH analysis in original tumor tissue using Vysis PathVysion DNA-based FISH technology. Results: ErbB2/CEP17 (R) provided additional predictive value for progression free survival (PFS) and time to first metastasis (TTM), but not for overall survival (OS) (all from start of trastuzumab containing treatment). The following cutoffs of Her-2/neu were identified: group A: 0–2.2 R (TTM: 49.8; OS: 6.7; PFS: 6.2); group B: 2.2- 6 R (TTM: 26.2; OS: 5.3; PFS: 9.3); group C: >6 CN (TTM: 20.1; OS: 3.9; PFS: 13.7) Kaplan-Maier analysis showed significant longer TTM for group A (p<0.01 vs. B/C), significant longer PFS for group C (p<0.01 vs. A/B). Significant differences in complete response (B/C: 16.9% vs C:44.4%), partial response (B/C: 20.2% vs. C: 33.3%) and progressive disease (B/C: 27% vs. 11.1%) were noted. No significant difference in overall survival between the groups was seen. Conclusions: ErbB/CEP17 R provides important prognostic information and, in metastatic patients, allows one to better predict response to trastuzumab-based treatment than the widely used binary classification of ErbB2 amplification that is based on a cut-off at a copy number of >2.2.

1090 Background: Circulating tumor cells (CTCs) are detected in 30–60% of patients with metastatic breast cancer (MBC). The aim of this prospective multi-center study was to evaluate the impact of CTCs on progression free survival (PFS) and overall survival (OS) in a large cohort of 486 patients with progressive metastatic disease. Methods: CTC levels were determined for 486 patients at nine German University Breast Cancer Centers between 12/2007 and 06/2011. Samples of 7.5 ml blood were taken before initiation of a new line of therapy and CTCs were enumerated using the CellSearch System (Veridex LLC, Raritan, NJ, USA). CTC status (≥ 5 CTCs vs. < 5 CTCs per 7.5 ml blood) was assessed as a prognostic factor for PFS and OS using univariate (log-rank test) and multivariate (Cox regression model) statistical methods. Results: CTCs were detected in 205/486 (42%) patients. The median CTC count was 2 (range 0–6380) per 7.5 ml blood. The presence of ≥ 5 CTCs/7.5 ml blood did not correlate with any of the established clinicopathological factors except estrogen receptor status (p = 0.038). PFS and OS were both significantly shorter in patients with ≥ 5 CTCs/7.5 ml than in those with < 5 CTCs/7.5 ml blood. PFS was 5.0 [95% CI 4.1–5.8] months vs.7.6 [95% CI 5.9–9.3] months, p < 0.001; and OS was 15.0 [95% CI 13.5–16.5] months vs. 18.3 [95% CI 17.4–19.2] months, p < 0.001. In the multivariate analysis considering all clinicopathological factors and the CTC status, independent predictors of reduced OS and PFS were site of metastasis (visceral vs. bone), number of metastatic sites (multiple sites vs. one site), and CTC status. Conclusions: The presence of ≥ 5 CTCs/7.5 ml blood is a strong and independent predictor of poor PFS and OS in patients with MBC.

55 Background: The aim of this retrospective study was to examine the overall survival (OS) of metastatic breast cancer patients over a decade and assess for any differences with respect to age, tumor characteristics, and ECOG status. Methods: Data on metastatic breast cancer cases from 1999-2010 were retrieved from the institutional cancer registry and linked to electronic medical records. Through chart review of 240 metastatic breast cancer cases, we determined hormone receptor (HR), HER2/neu (HER2), ECOG, age at diagnosis of metastatic cancer and mortality data. Kaplan-Meier survival curves for OS were used and compared between HR status, HER2 status, ECOG, and age at diagnosis using log-rank regression and Cox Regression analysis was performed to control for these variables. A 95% confidence interval (CI) was used. Results: The median OS of the sampled cases was 2.2 years (CI: 1.8-2.5 years). Analysis for overall survival by pre-determined age groups demonstrated no significant difference between the age groups (p value 0.46), but did yield a statistical difference based on ECOG status (p value 0.0001). Cox regression analysis showed consistent findings where survival was significantly affected by HR, HER2 status and ECOG but not age (HR: p value <0.0001; HER2: p value 0.0132; ECOG: p value <0.0001; age at diagnosis: p value 0.8462). Analysis for OS based on HR yielded a median survival of 1.4 years (CI: 0.9-1.6 years) for HR negative and 2.5 years (CI: 2.2-3.0 years) for HR positive (p value 0.0018). HER2 yielded a median survival of 1.8 years (CI: 1.4-2.3 years) for no amplification and 3.0 years (CI: 2.5 - 3.4 years) for amplification (p-value 0.0043). HR negative, HER2 non-amplified tumors had the poorest median OS at 0.7 years (CI: 0.5 - 1.1 years) whereas those tumors with HR positive, HER2 amplified had the best median OS at 3.0 years (CI: 2.5 - 4.7 years) with a p value < 0.0001. Conclusions: In this retrospective analysis, there was no significant survival difference with respect to age. Age continued to have no significant effect on survival when adjusting for ECOG, hormone status, and HER2/neu status. Those factors that did act as determinants of survival were ECOG status, hormone status and HER2/neu status of the tumor.

Aim: To describe real-world treatment patterns/outcomes among patients with HER2+ metastatic breast cancer (MBC). Materials & methods: Real-world treatments and overall survival (OS) were evaluated among adult women diagnosed with HER2+ MBC, with and without brain metastases (BMs), between June 1, 2012 and May 31, 2018 using electronic medical records from the Definitive Oncology Dataset. Results: Among 372 patients, 69% initiated first-line trastuzumab plus pertuzumab-based therapy; many therapy combinations were utilized in the second- to fourth-line. During follow-up (median 24.8 months), 18% of patients died (22% with and 16% without BMs). Mean OS was shortest among patients with BMs at MBC diagnosis in the third- and fourth-line. Conclusion: OS was poor, and no clear standard of care was observed among patients with HER2+ MBC progressing on trastuzumab-based therapies.
