146 Background: There are various treatment modalities for metastatic breast cancer to the brain (MBC-b), with wide variation of reported outcomes. Methods: There were 1,513 patients (pts) with MBC-b treated at MD Anderson Cancer Center October 2009-December 2012. We reviewed medical records of the first consecutive 1015 and included 792 with confirmed brain metastases (BM). A Cox multivariate model was used to identify the effect of treatment on time-to-progression in the brain (TTP-b) and overall survival (OS). Results: Disease subtypes: ER+/HER2- (27%); ER+/HER2+ (16%); ER-/HER2+ (18%); ER-/HER2- (29%), missing (10%). Number of BM: 1 (20%), >1 (73%), missing (7%). Local treatment: metastasectomy (S) (13%), radio-surgery (SRS) (12%), whole-brain radiation (WBRT) (57%), combination of S/SRS with WBRT (11%), no treatment (7%). Systemic treatment: Any (64%), HER2 directed (24%). Median OS was 11.33 months(m) (4.4-25.8). Clinical characteristics associated with OS in multivariate analysis: ER+, HER2+, age < 60, ECOG 0-1, single BM, controlled systemic disease at time of BM and <3 treatment lines before BM. After correction for covariates, use of systemic therapy was associated with longer OS (HR 0.35 CI 0.20-0.60, p < 0.001) regardless of subgroup: HER2+ (19.9 vs 3.5m), ER+/HER2- (12.7 vs 2.2m), ER-/HER- (10.5 vs 2.3m). In pts receiving trastuzumab at diagnosis of BM, continuation of HER2 therapy increased OS (HR 0.44 CI 0.25-0.77, p = 0.004) regardless of agent used (lapatinib vs trastuzumab p=0.7). OS was the same for S and SRS (p=0.7) and either one increased OS (HR 0.41 CI 0.21-0.79 p=0.008). WBRT prolonged OS in multiple BM (HR 0.61 CI 0.38-0.96); Median TTP-b was 11.07m (5-24). WBRT added to S/SRS had longer TTP-b than either modality alone (17.6m vs 10.4m HR 0.56 CI 0.37-0.85 p=0.006). Use of systemic therapy after diagnosis of BM increased TTP-b (11.8 vs 5.1m HR 0.55 CI 0.33-0.92 p = 0.024), but there was no difference between agents used (lapatininib vs trastuzumab p=0.79; capecitabine vs others p= 0.96). Conclusions: WBRT improved local control when done after S/SRS. The use of chemotherapy after local therapy improved time to progression in the brain and survival.

1005 Background: Tucatinib (TUC) is an investigational, highly selective HER2 kinase inhibitor. HER2CLIMB (NCT02614794) showed clinically meaningful and statistically significant improvements in overall survival (OS) and progression free survival (PFS) in all pts, prolongation of PFS in pts with brain metastases (BM), and objective response rate (ORR) when TUC was added to trastuzumab (T) and capecitabine (C). Primary methods and outcomes have been reported previously (Murthy NEJM 2019). We report the results of exploratory efficacy analyses in pts with BM. Methods: All pts with HER2+ metastatic breast cancer (MBC) enrolled in HER2CLIMB had a baseline brain MRI. Pts with BM were eligible and classified as untreated, treated stable, or treated and progressing. Pts were randomized 2:1 to receive TUC or placebo, in combination with T and C. Efficacy analyses in pts with BM at baseline were performed by applying RECIST 1.1 to the brain based on investigator evaluation. CNS-PFS (progression in the brain or death) and OS were evaluated in BM pts overall. Intracranial (IC) confirmed ORR (ORR-IC) and IC duration of response (DOR-IC) were evaluated in BM pts with measurable IC disease. After isolated brain progression, pts could continue study therapy after local treatment until second progression, and time from randomization to second progression or death was evaluated. Results: Overall, 291 pts (48%) had BM at baseline: 198 (48%) in the TUC arm and 93 (46%) in the control arm. There was a 68% reduction in risk of CNS-PFS in the TUC arm (HR: 0.32; 95% CI: 0.22, 0.48; P < 0.0001). Median CNS-PFS was 9.9 mo in the TUC arm vs 4.2 mo in the control arm. Risk of death overall was reduced by 42% in the TUC arm (OS HR: 0.58; 95% CI: 0.40, 0.85; P = 0.005). Median OS was 18.1 mo vs 12.0 mo. ORR-IC was higher in the TUC arm (47.3%; 95% CI: 33.7, 61.2) vs the control arm (20.0%; 95% CI: 5.7, 43.7). Median DOR-IC was 6.8 mo (95% CI: 5.5, 16.4) vs 3.0 mo (95% CI: 3.0, 10.3). In pts with isolated brain progression who continued study therapy after local treatment (n = 30), risk of second progression or death was reduced by 67% (HR: 0.33; 95% CI: 0.11, 1.02), and median PFS from randomization was 15.9 mo vs 9.7 mo, favoring the TUC arm. Conclusions: In pts with heavily previously treated HER2+ MBC with BM, TUC in combination with T and C doubled the ORR-IC, reduced risk of IC progression or death by two thirds and reduced risk of death by nearly half. If approved, TUC in combination with T and C has the potential to become a new standard of care in pts with HER2+ MBC with and without BM. Clinical trial information: NCT02614794 .

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that Rab11 family-interacting protein 4, encoded by RAB11FIP4, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. RAB11FIP4 mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast. Importantly, expression of RAB11FIP4 in primary tumors was significantly correlated with patient recurrence-free survival and distant metastasis-free survival. Modulation of RAB11FIP4 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.

PURPOSE: To investigate the value of the addition of either cisplatin (CDDP) or lonidamine (LND) to epirubicin (EPI) in the first-line treatment of advanced breast cancer. PATIENTS AND METHODS: Three hundred seventy-one metastatic breast cancer patients with no prior systemic chemotherapy for advanced disease were randomized to receive either EPI alone (60 mg/m2 on days 1 and 2 every 21 days), EPI and CDDP (30 mg/m2 on days 1 and 2 every 21 days), EPI and LND (450 mg orally daily, given continuously), or EPI, CDDP, and LND. Time to progression, response rates, side effects, and survival were compared according to the 2 × 2 factorial design of this study. RESULTS: The groups were well balanced with respect to prognostic factors. Time to progression did not differ in the comparison between CDDP arms and non-CDDP arms (median, 10.9 months v 9.4 months, respectively; P = .10) or between that of LND arms and non-LND arms (median, 10.8 months v 9.9 months, respectively; P = .47), nor did overall survival. The response rate did not significantly differ in the comparison between LND arms and non-LND arms (62.9% v 54.0%, P = .08). No difference in treatment activity was observed between CDDP arms and non-CDDP arms. Toxicity was significantly higher in the CDDP arms, leading to CDDP dose adjustment in 40% of cases. The most frequent side effects were of a hematologic and gastrointestinal nature. The addition of LND produced more myalgias and fatigue. CONCLUSION: Neither CDDP nor LND was able to significantly improve the time to progression obtained by EPI. CDDP, however, significantly worsened the drug’s tolerability.

Introduction: In advanced breast cancer, local treatment is considered palliative. However, although there are some polemic opinions about the surgical treatment, some of the latest studies have emphasized that in advanced cases primary tumor resection (PTR) is related to better outcomes. This review aims to evaluate how resection of the original tumor impacts women with metastatic breast cancer, considering the most recent studies about this subject. Methods: The search was performed in MEDLINE, Scopus, PMC, Current Contents and Wiley Online Library databases; 23 articles - from 2016 to 2019 - were selected and 11 were included in this review. As inclusion criteria were considered: studies presenting outcomes about resection of the primary tumor, comparison between chemotherapy/ hormone therapy/ targeted cancer therapies and surgical intervention, studies published from 2016 to 2019 and available in English, Spanish or Portuguese. We excluded those which did not approach PTR, did not present outcomes of interest (progression-free survival comparison between PTR and systemic therapy) or only discussed systemic therapy, as well as those published before 2016. Results: It was reported in 6 studies that progression-free survival is better on those who underwent surgery. PTR was also related to longer median overall survival in women submitted to surgery, up to 16 months higher when compared to the ones who were not. Enhanced survival even pertained to surgical groups regardless of tumor size.  Conclusion: Based in the analysis, PTR in metastatic breast cancer can be related to higher overall survival.

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). Between the breast and the brain reside the secondary lymphoid organ, the lymph nodes. We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the lymph nodes in humans with metastatic breast cancer. We found that collagen type XVI alpha 1 chain, COL16A1, was among the genes whose expression was most different in the lymph node metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. COL16A1 mRNA was present at decreased quantities in lymph node metastases as compared to primary tumors of the breast. Importantly, expression of COL16A1 in primary tumors of the breast was correlated with patient overall survival, in lymph node negative patients but not in lymph node positive patients. Modulation of COL16A1 expression may be relevant to the biology by which tumor cells metastasize from the breast to the lymph nodes and the brain in humans with metastatic breast cancer.
