Background: We retrospectively evaluated the correlation between a baseline measurement of circulating tumor cells (CTCs) and inflammation-based scores in patients with metastatic breast cancer (MBC). Methods: The optimal value of inflammation-based scores as the neutrophil–lymphocyte ratio (NLR), platelet–lymphocyte ratio (PLR), monocyte–lymphocyte ratio (MLR) and systemic immune-inflammation index (SII) to predict survival was determined and compared with CTC <5 or ⩾5 per 7.5 ml of blood. Results: In the overall population of 516 women with MBC, CTCs correlated with peripheral blood monocytes ( p = 0.008) and neutrophils ( p = 0.038). In triple-negative tumors, CTCs correlated with monocyte count ( p = 0.009); in HER2+ tumors, CTCs correlated with neutrophil count ( p = 0.009), with a trend versus monocyte count ( p = 0.061), whereas no correlation was found in HER2– estrogen receptor-positive (ER+) tumors. In multivariate analysis only monocytes were associated with ⩾5 CTCs (OR = 2.72, 95% CI 1.09–6.80, p = 0.033). In multivariable analysis for predictors of overall survival, CTC (⩾5 versus <5), number of metastatic sites (>1 versus 1), tumor subtypes (triple-negative versus HER2– ER+ tumors) and MLR only remained significant. Conclusions: CTC and MLR are predictors of overall survival in MBC. CTC correlates with monocytes, in particular in triple-negative tumors.

Th1 Immune Response

We previously reported that triple-negative breast cancer (BRCA) cells overexpress the cytokines GM-CSF, G-CSF, MCP-1, and RANTES, and when monocytes were 3-D co-cultured with them, M1-like macrophages were generated with the ability to induce aggressive features in luminal BRCA cell lines. These include upregulation of mesenchymal and stemness markers and invasion. In this study, we stimulated peripheral blood monocytes with the four cytokines and confirmed their capacity to generate protumoral M1-like macrophages. Using the METABRIC BRCA database, we observed that GM-CSF, MCP-1, and RANTES are associated with triple-negative BRCA and reduced overall survival, particularly in patients under 55 years of age. We propose an extended M1-like macrophage proinflammatory signature connected with these three cytokines. We found that the extended M1-like macrophage signature coexists with monocyte/macrophage, Th1 immune response, and immunosuppressive signatures, and all are enriched in claudin-low BRCA samples, and correlate with reduced patient overall survival. Furthermore, we observed that all these signatures are also present in mesenchymal carcinomas of the colon (COAD) and bladder (BLCA). The claudin-low tumor subtype has an adverse clinical outcome and remains poorly understood. This study places M1 macrophages as potential protumoral drivers in already established cancers, and as potential contributors to claudin-low aggressiveness and poor prognosis.

e18566 Background: We previously elucidated sociodemographic factors associated with risk-of-death, in a subgroup of patients with Stage IV human epidermal growth factor 2 (HER)+ breast cancer. To further understand determinants of disparities in all subgroups of stage IV breast cancer, this study sought to evaluate factors which are predictive of overall survival (OS) in a cohort of patients with metastatic breast cancer (MBC), according to the following subtypes: 1) estrogen receptor (ER)+ or progesterone receptor (PR)+ and (HER)-, (2) (ER+ or PR+) and HER+, (3) (ER- and PR-) and HER-, or (4) (ER- and PR-) and HER+. Methods: Study population included patients with MBC, extracted from the National Cancer Database, treated between 2010 and 2016. Descriptive statistics were used to summarize patient characteristics, and chi-square tests were performed to compare patient characteristics, by ethnic group (white, black, Hispanic, Asian, and other). Multivariate Cox regression models with backward elimination (using significance level of p<0.05) were utilized to compare overall survival among patient cohorts. In addition, Kaplan-Meier survival curves of patient cohort were also produced. Statistics were performed using SAS. Results: Records from n= 47,032 patients were included, the majority were 50 years or older, white, and treated with hormonal therapy. With a median follow-up time of 2.3 years, disparities in OS were observed; black patients were more likely to suffer death (HR=1.12 (1.08-1.16), p<0.0001), compared to white patients. Additional factors contributing to risk of death in MBC included: being male (HR=1.12, (1.02-1.23), p=0.019), having visceral involvement compared to bone only (HR=1.52, (1.05-1.28), p<0.0001), income < $38,000 (HR=1.13 (1.09-1.17), p<0.0001), being on government insurance (HR=1.24, (1.20-1.27), p<0.0001, and having Triple Negative Breast Cancer (ER- and PR-) and HER- status (HR=1.68 (1.60-1.75) p<0.0001). Patients who receive chemotherapy, not hormonal therapy (HR=1.25 (1.2 – 1.3), p<0.0001), were found to have worse prognosis possibly reflecting biology of disease at presentation and lack of specific targeted therapy. Conclusions: This study confirms that sociodemographic disparities exist in OS among patients within the same stage of MBC, and regardless of receptor status subtypes. Clinical practice should focus on closing disparities gaps for those with advanced and MBC, especially among Black, impoverished, and male patients. Better treatment approaches should be sought for patients with visceral metastasis and those diagnosed with triple negative receptor status, who continue to suffer from worse outcomes.

AbstractThe prognostic impact of neutrophil-lymphocyte ratio (NLR) in metastatic breast cancer (MBC) has been previously evaluated in early and metastatic mixed breast cancer cohorts or without considering other relevant prognostic factors. Our aim was to determine whether NLR prognostic and predictive value in MBC was dependent on other clinical variables. We studied a consecutive retrospective cohort of patients with MBC from a single centre, with any type of first line systemic treatment. The association of NLR at diagnosis of metastasis with progression free survival (PFS) and overall survival (OS) was evaluated using Cox univariate and multivariate proportional hazard models. In the full cohort, that included 263 MBC patients, a higher than the median (>2.32) NLR was significantly associated with OS in the univariate analysis (HR 1.36, 95% CI 1.00–1.83), but the association was non-significant (HR 1.12, 95% CI 0.80–1.56) when other clinical covariates (performance status, stage at diagnosis, CNS involvement, visceral disease and visceral crisis) were included in the multivariate analysis. No significant association was observed for PFS. In conclusion, MBC patients with higher baseline NLR had worse overall survival, but the prognostic impact of NLR is likely derived from its association with other relevant clinical prognostic factors.

Background: We directly compared CTC detection rates and prognostic significance, using three different methods in patients with breast cancer (BC). Methods: Early (n=200) and metastatic (n=164) patients were evaluated before initiating adjuvant or first-line chemotherapy, using the CellSearchTM System, an RT-qPCR for CK-19 mRNA detection and by double immunofluorescence (IF) microscopy using A45-B/B3 and CD45 antibodies. Results: Using the CellSearchTM System, 37% and 16.5% of early BC patients were CTC-positive (at ≥1 and ≥2 CTCs/23 ml of blood), 18.0% by RT-qPCR and 16.9% by IF; no agreement was observed between methods. By the CellSearchTM 34.8% and 53.7% (at≥ 5 and ≥ 2 CTCs/7.5 ml) of metastatic patients were CTC-positive, 37.8% by RT-qPCR and 28.5% by IF. A significant agreement existed only between the CellSearchTM and RT-qPCR. In 60.8% of cases, differential EpCAM and CK-19 expression on CTCs by IF could explain the discrepancies between the CellSearchTM and RT-qPCR. CTC-positivity by either method was associated with decreased overall survival in metastatic patients. Conclusion: A significant concordance was observed between the CellSearchTM and RT-qPCR in metastatic but not in early BC. Discordant results could be explained in part by CTC heterogeneity. CTC detection by all methods evaluated had prognostic relevance in metastatic patients.

Evidence suggests that the DNA end-binding protein p53-binding protein 1 (53BP1) is down-regulated in subsets of breast cancer. Circulating tumor cells (CTCs) provide accessible “biopsy material” to track cell traits and functions and their alterations during treatment. Here, we prospectively monitored the 53BP1 status in CTCs from 67 metastatic breast cancer (MBC) patients with HER2- CTCs and known hormone receptor (HR) status of the primary tumor and/or metastases before, during, and at the end of chemotherapeutic treatment with Eribulin. Nuclear 53BP1 staining and genomic integrity were evaluated by immunocytochemical and whole-genome-amplification-based polymerase chain reaction (PCR) analysis, respectively. Comparative analysis of CTCs from patients with triple-negative and HR+ tumors revealed elevated 53BP1 levels in CTCs from patients with HR+ metastases, particularly following chemotherapeutic treatment. Differences in nuclear 53BP1 signals did not correlate with genomic integrity in CTCs at baseline or with nuclear γH2AX signals in MBC cell lines, indicating that 53BP1 detected features beyond DNA damage. Kaplan–Meier analysis revealed an increasing association between nuclear 53BP1-positivity and progression-free survival (PFS) during chemotherapy until the final visit. Our data suggest that 53BP1 detection in CTCs could be a useful marker to capture dynamic changes of chemotherapeutic responsiveness in triple-negative and HR+ MBC.

The Impact

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.
