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.

Background: Elevated plasmatic lactate dehydrogenase (LDH) levels are associated with worse prognosis in various malignancies, including metastatic breast cancer (MBC). Nevertheless, no data are available on the prognostic role of LDH as a dynamic biomarker during first-line treatment in unselected MBC. Methods: We reviewed data of 392 women with MBC to evaluate the association between LDH variation after 12 weeks of first-line treatment and survival. The prognostic impact was tested by multivariate Cox regression analysis. Results: Plasmatic LDH was confirmed as an independent prognostic factor in MBC. Patients who maintained elevated LDH levels after 12 weeks of first-line treatment experienced worse progression-free survival (PFS, HR 2.88, 95% CI: 1.40–5.89, p = 0.0038) and overall survival (OS, HR 2.61, 95% CI 1.16–5.86, p = 0.02) compared to patients with stable normal LDH levels, even after adjustment for other prognostic factors. Notably, LDH low-to-high variation emerged as an unfavorable prognostic factor for PFS (HR 3.96, 95% CI 2.00–7.82, p = 0.0001). Conclusions: Plasmatic LDH and its variation during first-line treatment predict PFS and OS in MBC, providing independent prognostic information. It would be worthwhile to prospectively evaluate the association between LDH variation and therapeutic benefit in MBC, and explore how it may affect treatment strategies.

Abstract Background Patients diagnosed with metastatic breast cancer have poor outcome with a median survival of approximately 2 years. While novel therapeutic options are urgently needed, the great majority of breast cancer research has focused on the primary tumor and less is known about metastatic breast cancer and the prognostic impact of the metastatic tumor microenvironment. Here we investigate the immune landscape in unique clinical material. We explore how the immune landscape changes with metastatic progression and elucidate the prognostic role of immune cells infiltrating primary tumors and corresponding lymph node and more importantly distant metastases. Methods Immunohistochemical staining was performed on human breast cancer tissue microarrays from primary tumors (n = 231), lymph node metastases (n = 129), and distant metastases (n = 43). Infiltration levels of T lymphocytes (CD3+), regulatory T lymphocytes (Tregs, FOXP3+), macrophages (CD68+), and neutrophils (NE+) were assessed in primary tumors. T lymphocytes and Tregs were further investigated in lymph node and distant metastases. Results T lymphocyte and Treg infiltration were the most clinically important immune cell populations in primary tumors. Infiltration of T lymphocytes and Tregs in primary tumors correlated with proliferation (P = 0.007, P = 0.000) and estrogen receptor negativity (P = 0.046, P = 0.026). While both T lymphocyte and Treg infiltration had a negative correlation to luminal A subtype (P = 0.031, P = 0.000), only Treg infiltration correlated to luminal B (P = 0.034) and triple-negative subtype (P = 0.019). In primary tumors, infiltration of T lymphocytes was an independent prognostic factor for recurrence-free survival (HR = 1.77, CI = 1.01–3.13, P = 0.048), while Treg infiltration was an independent prognostic factor for breast cancer-specific survival (HR = 1.72, CI = 1.14–2.59, P = 0.01). Moreover, breast cancer patients with Treg infiltration in their distant metastases had poor post-recurrence survival (P = 0.039). Treg infiltration levels changed with metastatic tumor progression in 50% of the patients, but there was no significant trend toward neither lower nor higher infiltration. Conclusion Treg infiltration could have clinical applicability as a prognostic biomarker, deciphering metastatic breast cancer patients with worse prognosis, and accordingly, could be a suitable immunotherapeutic target for patients with metastatic breast cancer. Importantly, half of the patients had changes in Treg infiltration during the course of metastatic progression emphasizing the need to characterize the metastatic immune landscape.

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.

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.

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.

Abstract Background: Relevant study had demonstrated that Paraoxonase-1 (PON1) had relationship with occurrence and development of tumors which suggested that PON1 was a key gene in promoting tumor progression. However, the relationship between PON1 and Kidney renal clear cell carcinoma (KIRC) is still unclear so far. Methods: We downloaded relevant data about KIRC from TCGA dataset and compared it with normal renal tissues. Immunohistochemistry (IHC) was applied to analyze the expression of PON1. Univariate cox regression analysis and multivariate cox regression analysis were also utilized to analyze independent factors associated with prognosis. Gene set enrichment analysis was conducted to find the signaling pathways of PON1 in KIRC. Finally, we also investigated whether PON1 had relationship with immunity. Results: As shown in results, PON1 expression was decreased in KIRC compared with adjacent paracancer tissues. Immunohistochemistry (IHC) was utilized to find the expression of PON1. After survival analysis, the high expression of PON1 was significantly related to overall survival (P<0.001). Univariate/Multivariate cox regression analysis both revealed that PON1 could serve as an independent prognostic factor. To analyze overall survival (OS) of patients with KIRC, nomogram was developed. GSEA revealed that PON1 was correlated with homologous recombination. Besides, PON1 had few relationships with immunity. Conclusions: Our results revealed that PON1 could serve as an independent prognostic factor for KIRC, providing a novel target for KIRC future treatments.

Abstract Background: Accumulating evidences indicate that the signal peptide-CUB-EGF-like domain-containing protein 3 (SCUBE3) plays a key role in the development and progression of many human cancers. However, the underlying mechanism and prognosis value of SCUBE3 in breast cancer are still unclear. Methods: The clinical data of 137 patients with breast cancer who underwent surgical resection in Taizhou Hospital of Zhejiang Province were retrospectively analyzed. We first conducted a comprehensive study on the expression pattern of SCUBE3 using the Tumor Immune Estimation Resource (TIMER) and UALCAN databases. In addition, the expression of SCUBE3 in breast tumor tissues was confirmed by immunohistochemistry. The protein-protein interaction analysis and functional enrichment analysis of SCUBE3 were analyzed using the STRING and Enrichr databases. Moreover, tissue microarray (TMA) was used to analyze the relationship between SCUBE3 expression levels and clinical-pathological parameters, such as histological type, grade, the status of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor (HER2). We further supplemented and identified the above results using the UALCAN and bc-GenExMiner v4.4 databases from TCGA data. The correlation between the expression of SCUBE3 and survival was calculated by multivariate Cox regression analysis to investigate whether SCUBE3 expression may be an independent prognostic factor of breast cancer. Results: We found that the expression level of SCUBE3 was significantly upregulated in breast cancer tissue compared with adjacent normal tissues. The results showed that the distribution of breast cancer patients in the high expression group and the low expression group was significantly different in ER, PR, HER2, E-cadherin, and survival state (p < 0.05), but there was no significant difference in age, histologic grade, histologic type, tumor size, lymph node metastasis, TMN stage, subtypes, or recurrence (p > 0.05). In addition, the high expression of SCUBE3 was associated with relatively poor prognosis of ER- (p = 0.012), PR- (p = 0.029), HER2+ (p = 0.007). The multivariate Cox regression analysis showed that the hazard ratio (HR) was 2.80 (95 % CI: 1.20-6.51, p = 0.0168) in individuals with high SCUBE3 expression, and HR was increased by 1.86 (95 % CI: 1.06-3.25, p = 0.0300) for per 1-point increase of SCUBE3 expression.Conclusions: These findings demonstrate that the high expression of SCUBE3 indicates poor prognosis in breast cancer. SCUBE3 expression may serve as a potential diagnostic indicator of breast cancer.
