Improved patient outcomes with next-generation HER2-targeted ADCs (ID 341)
95MO - Characteristics of patients with brain metastases from HER2-positive breast cancer (ID 267)
Abstract
Background
About 40% of patients with a metastatic HER2+ breast cancer (BC) develop brain metastases (BM). A better understanding of clinical features of patients with HER2+ BC with BM is required.
Methods
A total of 2948 patients of the Brain Metastases in Breast Cancer (BMBC) Registry were available for this analysis, 1311 of them had a HER2+ subtype.
Results
Patients with a HER2+ BC and BM were,compared to HER2- patients, slightly younger at BC diagnosis (median 52 vs 53 years, p<0.001) and BM diagnosis (median 55 vs 58 years, p<0.001), had a higher pathological complete response rate after neoadjuvant chemotherapy (21.5 vs 12.2%, p=0.002), higher tumor grading (G3 59.5 vs 56.5%, p<0.001) and had less common extracranial metastases (ECM) at BM diagnosis (77.7 vs 80.0%, p<0.001). HER2+ patients had significantly more often BM in the posterior fossa (57.9 vs 49.0%, p<0.001) but less common leptomeningeal metastases (LM) (9.3 vs 19.1%, p<0.001). Hormone-receptor-positive HER2+ patients were younger at BC diagnosis (median 50 vs 53 years, p=0.03), had a smaller initial BC (<5cm: 78.4 vs 66.3%, p=0.002), a lower grading of the primary tumor (G1/G2: 46.1 vs 29.9%, p<0.001) and more often LM (11.3 vs 6.8%, p=0.007). The median overall survival (OS) in all HER2+ patients was 13.2 months (95% CI 11.4-14.4). The following factors were associated with a worse OS (multivariate analysis): older age (≥60 vs <60 years: Hazard Ratio [HR] 1.63, p<0.001), lower performance status (ECOG 2-4 vs 0-1: HR 1.58, p<0.001), greater number of BM (2-3 vs 1 BM: HR 1.36; ≥4 vs 1 BM: HR 1.53, p=0.003; overall p=0.012), BM in fossa anterior (HR 1.71, p<0.001), LM (HR 1.62, p=0.027), BM with neurological symptoms at diagnosis (HR 1.38, p=0.029), ECM at diagnosis of BM (HR 1.44, p=0.02) and the absence of targeted therapy (HR 0.625, p=0.001). Although progression-free survival did not differ in HER2+ patients according to hormone-receptor status, a significantly better OS could be observed for hormonereceptor-positive patients (median 14.3 vs 10.9 months, p=0.027).
Conclusions
The performed analysis identified factors associated with prognosis of HER2+ patients with BM. Further research is needed to understand the factors determining the longer survival of HER2+ hormonereceptor-positive patients.

21P - BACH1 and HIF1α predict response to neoadjuvant nab-paclitaxel (nP) treatment in early breast cancer (BC)
Abstract
Background
Hypoxia occurs in most solid tumors including BC and may negatively impact treatment response. We investigate the incidence of BACH1 (a key regulator of mitochondrial metabolism) and HIF1α (a hypoxia-inducible factor) expressions and their correlation with clinical outcomes in early HER2-negative BC.
Methods
We correlated tumor BACH1 and HIF1α mRNA expression from available RNA-Seq data with pathological complete response (pCR), disease-free survival (DFS) and overall survival (OS) in the GeparSepto trial (NCT01583426), which randomized pts with early-stage BC to either neoadjuvant solvent-based paclitaxel (P) or nP followed by EC. BACH1 and HIF1α values were analyzed as a continuous variable and categorized as low and high by median cut-off. Multivariate logistic (for pCR) and Cox (DFS and OS) regressions were used to adjust for age, cT, and cN.
Results
RNA-Seq expression data was available for 279 out of 810 HER2-negative BC pts, median age was 49 years (range 22-76) and median follow-up 49.8 months (range 2.3-62.4). There was a positive correlation between BACH1 and HIF1A expression levels (Pearson correlation 0.498). Overall, BACH1 and HIF1α continuous expressions were significantly associated with increased pCR (OR=4.21 [95%CI 1.44-12.30), p=0.009), OR=2.08 [95%CI 1.14-3.82], p=0.018, respectively) but did not impact survival in multivariate models. The table shows effects of BACH1 and HIF1α expression in nP vs P arm, both high BACH1 and HIF1α expressions were significant independent predictors of pCR and were associated with numerically better survival *OR/HR (nP vs P groups) in multivariate model **interaction test (BACH1 high/HIF1α high by nP arm) p value, multivariate model.

Conclusions
HER2-negative BC with elevated BACH1 and HIF1α expression benefits from nP-based treatment. There was a positive correlation between increased BACH1 and HIF1α levels for predicting pCR. We suggest that high BACH1 and HIF1α expressions enhance the efficacy of nP treatment, perhaps through triggering the hypoxic tumor adaptation.

28P - EVI1 expression in early-stage breast cancer patients treated with neoadjuvant chemotherapy
Abstract
Background
Overexpression of the proto-oncogene EVI1 has been implicated as a prognostic factor in breast cancer (BC), particularly triple-negative BC (TNBC). The purpose of this study was to investigate frequency and clinical relevance of EVI1 expression in newly diagnosed BC treated with neoadjuvant chemotherapy.
Methods
EVI1 expression was determined by immunohistochemistry in pretherapeutic biopsies of BC patients treated with anthracycline/taxane based neoadjuvant chemotherapy within the GeparTrio trial. EVI1 expression was analyzed as a continuous variable and dichotomized into low or high based on median expression. Logistic regression and Cox proportional hazard models were used to correlate EVI1 expression with pathological complete response (pCR) and survival outcome, respectively. Disease-free survival (DFS) and overall survival (OS) rates according to EVI1 dichotomized expression were estimated with Kaplan-Maier curves with log-rank p-values.
Results
Of the 993 tumors with evaluable EVI1, 50.8% were HR+/HER2-, 15% HR+/HER2+, 9.8% HR-/HER2+, and 24.5% TNBC. Median EVI1 H-score was 112.16 (range 0.5-291.4). High EVI1 expression was more frequently observed in HR+/HER2- (52%) and TNBC (25%) compared to 13% in HR+/HER2+ and 10% in HR-/HER2+ and was significantly associated with smaller tumor size (cT1-2, p=0.004) in HR+/HER- BC. Elevated EVI1 levels were not significantly associated with therapy response and survival in the overall cohort. However, TNBC patients with high EVI1 showed a trend towards higher pCR rates compared to low EVI1 group (37.7% vs 27.5%, p=0.072; odds ratio 1.60 (95%CI 0.90-2.85, p=0.110) and numerically better survival (DFS: HR=0.77 [95%CI 0.48-1.23], log-rank p=0.271); OS: (HR=0.76 [95% 0.44-1.31], log-rank p=0.314).
Conclusions
EVI1 did neither influence response to neoadjuvant therapy nor patient survival in the overall cohort. TNBC patients with elevated EVI1 expression showed numerically better pCR and improved survival. Further analyses are needed to verify our findings, especially in the pathological work-up of newly diagnosed TNBC patients.
