Abstract
BACKGROUND Although multiple sclerosis (MS) Intimacy and Sexuality Questionnaire-19 (MSISQ-19) is a widely applied tool, no unique definition of sexual dysfunction (SD) based on its score exists. OBJECTIVE To explore the impact of different MSISQ-19 cut-offs on SD prevalence and associated risk factors, providing relevant information for its application in research and clinical settings. METHODS After defining SD according to two different MSISQ-19 cut-offs in 1155 people with MS (pwMS), we evaluated SD prevalence and association with sociodemographic and clinical features, mood status and disability via logistic regression. RESULTS Depending on the chosen cut-off, 45% to 54% of pwMS reported SD. SD defined as MSISQ-19 score >30 was predicted by age (OR=1.01, p=0.047), cognition (OR=0.96, p=0.004) and anxiety (OR=1.03, p=0.019). SD defined as a score >3 on any MSISQ-19 item was predicted by motor disability (OR=1.12, p=0.003) and cognition (OR= 0.96, p=0.002). CONCLUSION Applying different MSISQ-19 cut-offs influences both the estimated prevalence and the identification of risk factors for SD, a finding that should be considered during study planning and data interpretation. Preserved cognition exerts a protective effect towards SD regardless from the specific study setting, representing a key point for the implementation of preventive and therapeutic strategies.

Abstract
BACKGROUND Patients with HER2+ breast cancer (BC) frequently develop leptomeningeal metastases (LM). While HER2-targeted therapies have demonstrated efficacy in the neoadjuvant, adjuvant, and metastatic settings, including for parenchymal brain metastases, their efficacy for patients with LM has not been studied in a randomized controlled trial. However, several single-armed prospective studies, case series and case reports have studied oral, intravenous, or intrathecally administered HER2-targeted therapy regimens for patients with HER2+ BC LM. METHODS We conducted a systematic review and meta-analysis of individual patient data to evaluate the efficacy of HER2-targeted therapies in HER2+ BC LM in accordance with PRISMA guidelines. Targeted therapies evaluated were trastuzumab (intrathecal or intravenous), pertuzumab, lapatinib, neratinib, tucatinib, trastuzumab-emtansine and trastuzumab-deruxtecan. The primary endpoint was overall survival (OS), with CNS-specific progression-free survival (PFS) as a secondary endpoint. RESULTS 7780 abstracts were screened, identifying 45 publications with 208 patients, corresponding to 275 lines of HER2-targeted therapy for BC LM which met inclusion criteria. In univariable and multivariable analyses, we observed no significant difference in OS and CNS-specific PFS between intrathecal trastuzumab compared to oral or intravenous administration of HER2-targeted therapy. Anti-HER2 monoclonal antibody-based regimens did not demonstrate superiority over HER2 tyrosine kinase inhibitors. In a cohort of 15 patients, treatment with trastuzumab-deruxtecan was associated with prolonged OS compared to other HER2-targeted therapies and compared to trastuzumab-emtansine. CONCLUSIONS The results of this meta-analysis, comprising the limited data available, suggest that intrathecal administration of HER2-targeted therapy for patients with HER2+ BC LM confers no additional benefit over oral and/or IV treatment regimens. Although the number of patients receiving trastuzumab deruxtecan in this cohort is small, this novel agent offers promise for this patient population and requires further investigation in prospective studies.

Abstract
Abstract
Background: Neoadjuvant chemotherapy (NAC) is standard of care for the majority of patients with clinical stage II-III triple negative breast cancer (TNBC) and is considered in high-risk patients with hormone receptor positive (HR+)/human epidermal growth factor receptor 2 (HER2) negative (-) tumors, with expected pathological complete response (pCR) rates of 40-60% and 10-12%, respectively. In HER2- patients with residual disease (RD) after NAC, there is limited data on rates of gain of HER2 amplification. The biological and clinical significance of this phenomenon is unknown and determining the best adjuvant therapy for these patients remains a challenge. We sought to determine the rate of HER2 gain in a cohort of consecutive patients with HER2- breast cancer (BC) treated with NAC.
Methods: From 01/2021 to 12/2021, we identified patients with HER2- breast cancer treated with NAC followed by surgery at our institution. Patients who received neoadjuvant endocrine therapy were excluded. The rates of pCR (ypT0/is ypN0) and HER2 status pre- and post-NAC were assessed. Estrogen receptor (ER), progesterone receptor (PR) and HER2 status on surgery specimens were internally determined for all patients using ASCO/CAP 2020 guidelines. ER-low was defined as ER expression by immunohistochemistry (IHC) 1-10%.
Results: We included 256 patients, 130 (51%) HR+/HER2- [13/130(10%) ER-low] and 126 (49%) TNBC. Median age was 48 years (range 25-82) and the majority presented with clinical T2 (57%) and N1 (59%). Of 130 patients with HR+/HER2-tumors, 120 (92%) received dose-dense (dd) doxorubicin/cyclophosphamide-paclitaxel (AC-T). Of 126 TNBC patients, 46 (37%) received ddAC followed by carboplatin in combination with paclitaxel +/- pembrolizumab. Centralized HER2 status assessment on the core biopsy was performed in 22% of samples. Overall, pCR was achieved in 40% of TNBC and 11% of HR+/HER2-. Among the 192 patients with RD, the rate of HER2 gain was 8/192 (4%), including 3% (2/76) of TNBC and 5% (6/116) of HR+/HER2- patients. 7 of the 8 patients (88%) converted from IHC 1+ or 2+ fluorescence in situ hybridization (FISH) not amplified on core biopsy to IHC 2+ FISH amplified on the surgical specimen. In only 1 case, the HER2 status converted from IHC2+ FISH not amplified to IHC3+. 3/8 patients had multifocal disease. All 6 patients with HR+/HER2- BC and HER2 gain had high (>90%) ER expression (Table 1). All but one patient with HER2 gain received adjuvant anti-HER2 therapy. After a median follow-up of 10 months, no recurrence events occurred in this group.12 of the remaining 184 patients experienced a recurrence [11 distant recurrences (8 and 3, in the TNBC and HR+/HER2- groups, respectively), and there was 1 local event (localized chest wall recurrence) in the HR+/HER2- group].
Conclusions: At a single center, we found that in patients with HER2- BC treated with NAC, HER2 gain in patients with RD was uncommon and occurred more frequently in those with HR+ tumors. Analysis of a larger cohort is ongoing to corroborate these results. It is remains to be determined if this phenomenon represents a true HER2 status conversion or tumor heterogeneity.

Abstract
Abstract
Background: Varying levels of HER2 expression without ERBB2 gene amplification can be detected by immunohistochemistry (IHC) in approximately 60% of all invasive breast cancers (BCs). HER2-low-expressing BCs have recently been shown to respond to novel anti-HER2 antibody drug conjugates. Several studies have demonstrated that HER2-low BCs do not seem to constitute a distinct clinical and transcriptomic subtype as compared to HER2-0 BCs. Here we sought to define the clinicopathologic features and repertoire of somatic genetic alterations in HER2-low BCs. Methods: We retrieved clinical, pathological, and genomic data of BCs that were subjected to targeted sequencing using the FDA-cleared MSK-IMPACT assay from April 2014 to December 2021. After removing cases where any available biopsy had HER2 3+ and/or positive ERBB2 fluorescence in situ hybridization (FISH), 3608 samples (primary=1347; post-treatment/metastatic=2261) were included. Tumors were classified as HER2-low if they had an HER2 IHC score of 1+ or 2+ with a non-amplified FISH assay and HER2-0 if they had an HER2 IHC score of 0. Somatic mutations and DNA copy number alterations from MSK-IMPACT were analyzed. Multiple testing correction using the Benjamini-Hochberg method was applied to control for the false discovery rate (q). Q values < 0.1 were considered significant. Results: Among 3608 HER2- BCs, 1460 (40%) and 2148 (60%) were HER2-0 and HER2-low, respectively. Hormone receptor (HR) expression was significantly higher in HER2-low than HER2-0 tumors in both primary (781 [68.3%] vs 362 [31.7%]; p< 0.001) and metastatic (1031 [60.5%] vs 673 [39.5%]; p< 0.001) samples. A higher proportion of HER2-low tumors was found in metastatic than primary samples (59% vs 41%; p< 0.001) in this cohort. No difference in histology subtype, tumor grade, disease stage (among primary tumors), mutational signatures, and tumor mutational burden was found overall and when cases were stratified by HR expression. In HR-positive BCs, HER2-0 BCs harbored higher frequency of TP53 (33% vs 25%; odds ratio [OR] 1.49, 95% confidence interval [CI] 1.25-1.78, q< 0.001) and CDKN1A (1% vs 0%; OR 17.47, 95% CI 2.48-756.37, q=0.02) alterations than HER2-low BCs. Similar findings were observed in metastatic but not in primary HR-positive BCs. No differences were detected in HR-negative BCs stratified into HER2-low and HER2-0. Given the potential misclassification that exists between IHC HER2-0 and HER2-1+, we then conducted an exploratory analysis splitting the HER2-low group into HER2 1+ and 2+. TP53 alterations remained significantly enriched in HER2-0 compared to HER2-1+ HR-positive tumors (33% vs 24%; OR 1.55, 95% CI 1.28-1.87, q< 0.001). In HR-positive BCs, HER2-2+ displayed a higher frequency of genetic alterations in genes encoding for transcription factors, such as MYC (14.2% vs 7.3%; OR 2.09, 95% CI 1.44-3.04, q=0.02) and YAP1 (2% vs 0.3%; OR 6.86, 95% CI 1.7-39.57, q=0.1), and DNA damage response, such as FAM175A (1.6% vs 0%; OR 18.23, 95% CI 2.43-807.73, q=0.03) and BRCA2 (4% vs 1%; OR 3.09, 95% CI 1.49-6.55, q=0.1), than HER2-0 tumors. In HR-negative HER2-2+ tumors, a higher frequency of PIK3CA mutations was observed in comparison to HER2-0 (36.9% vs 19.5%; OR 2.41, 1.4-4.1, q=0.1), overall and in the metastatic setting. Conclusions: HER2-low BCs seem not to represent a distinct pathologic subtype. At the genomic level, however, some differences were identified and these became more conspicuous upon subclassification of HER2 IHC expression into 1+ and 2+. Further investigation into methods that more accurately detect and quantify low levels of HER2 expression in BC samples as well as better characterize the biology behind the HER2-low/ultralow expression is warranted.

Abstract
Abstract
Background: HER2 positive (HER2+) breast cancers harboring downstream MAPK or PI3K pathway alterations manifest persistent downstream signaling on anti-HER2 inhibitors with metastatic patients having worse outcomes on first line trastuzumab and pertuzumab (HP) therapy. However, HER2 antibody-drug conjugates (ADCs) are not as dependent upon potent signal transduction inhibition to exert their antitumor effects. To further investigate, we sought to determine whether MAPK and/or PI3K alterations affect the biologic or clinical outcomes of patients and models receiving HER2 ADCs. Methods: We performed prospective genomic sequencing using MSK-IMPACT on patients with advanced HER2+ breast cancer who received trastuzumab emtansine (T-DM1) in the metastatic setting between March 2013 and July 2021. We collected detailed information on clinical outcomes and correlates through our institutional IRB-approved retrieval process. HER2/ER/PR status at the time of metastatic recurrence were defined as per ASCO/CAP guidelines. Cox proportional hazard models were used to determine the association between MAPK and PI3K pathways alterations and progression-free survival (PFS) on T-DM1. Common mutations associated with outcomes were modeled in HER2+ breast cancer cell lines using short hairpin RNAs and CRISPR/Cas9, and the sensitivity to HER2 ADC was evaluated via cell proliferation and xenograft assays. Results: We identified 185 HER2+ breast cancer patients treated with T-DM1 at any line (median: 5) whose primary (N=65) or metastatic (N=120) tumor samples were sequenced. Median age was 55 (range: 20-87). The majority of the patients received T-DM1 in 2nd or 3rd line (52%) and received prior trastuzumab or HER2 TKI in metastatic setting (96%). 74/185 (40%) had de novo metastatic breast cancer and 119/185 (64%) had ER/PR+/HER2+ disease. Pathogenic activating alterations involving the MAPK pathway were observed in 14% of patients with the most frequent alterations being ERBB2 activating mutations (42%) and NF1 loss (34%). PI3K pathway alterations were identified in 42% of the patients, the majority being activating mutations of PIK3CA (87%). MAPK alterations were significantly enriched in the metastatic tumors compared to the treatment-naïve primaries (20% vs 3%, p=0.001), while PI3K alterations were not (44% vs 40%, p=0.6). To reduce the possible confounding resistance mechanisms induced by prior treatment, we restricted the survival analyses to patients who received T-DM1 up to 3rd line of therapy (N=100). On multivariable analysis adjusted for ER/PR status (positive vs negative), stage at the presentation of metastatic disease (de novo metastatic vs recurrence), treatment line and type of sequenced sample (primary vs metastatic), patients with MAPK (N=14) and PI3K (N= 38) alterations had similar PFS compared to wild type (HR 1.20, 95%CI 0.62-2.30, p=0.6 and HR 1.23, 95%CI 0.77-1.95, p=0.4, respectively). Similar results were found in the combined analysis including alterations in either pathway (N=48, HR 1.28, 95%CI 0.81-2.04, p=0.3). To verify the antiproliferative effect of HER2 ADCs on breast cancer cells with MAPK pathway activation, we depleted NF1 in a panel of HER2+ breast cancer cell lines. Consistently, MAPK-altered cell lines were sensitive to FDA-approved HER2 ADCs including trastuzumab deruxtecan (T-DXd). Conclusions: In contrast to H/P therapy, T-DM1 therapy was equally effective in tumors with downstream PI3K or MAPK alterations and wild type tumors. Expanded analysis on a larger cohort, including a subgroup of patients treated with novel HER2 ADCs such as T-DXd will be presented. The characterization of PI3K and MAPK pathways status in metastatic HER2+ breast cancer may inform prioritization of treatment options.

Background: Cyclin E1 (CCNE1) plays a critical role in cell cycle regulation. CCNE1 overexpression and/or gene amplification (amp) have been associated with poor outcome in several tumors, including breast cancer (BC). CCNE1 amp has recently been identified as a potential therapeutic target for novel synthetic lethality-based therapies. Here we sought to define the clinical and genomic features of BCs carrying CCNE1 amp. Methods: Genomic and clinical data from all consecutive BCs, which had been subjected to targeted sequencing using the FDA-authorized MSK-IMPACT assay from April 2014 to December 2021, were retrieved. Allele-specific copy number and fraction genome altered (FGA) were assessed using FACETS. Whole genome doubling (WGD) status was inferred from MSK-IMPACT sequencing data. Samples were categorized as CCNE1 amp or non-amp based on copy number profile assessed by FACETS. Mutual exclusivity and co-occurrence analyses between CCNE1 amp and other genetic alterations were performed using CoMEt. Multiple testing correction using the Benjamini–Hochberg procedure was applied to control for the false discovery rate. Progression-free survival (PFS) was assessed by Kaplan Meier method and Cox proportional-hazards models. Survival analyses were restricted to only patients with available pre-treatment samples. Results: Of 3,753 BCs with full clinical and genomic data, 125 (3.3%) harbored CCNE1 amp. A significant difference in the proportion of CCNE1 amp between treatment-naïve and post-treatment/metastatic samples was observed (2.4% vs 4%, p=0.007). CCNE1 amp was significantly less frequently detected in hormone receptor (HR)+/HER2- BCs than in HR-/HER2+ and HR-/HER2- subtypes (2% vs 7.6% and 7.2%, respectively, p< 0.001), and was particularly rare in invasive lobular BCs (1/452 cases). BCs with CCNE1 amp displayed a higher frequency of WGD (p< 0.001) and higher median FGA (p< 0.001) than non-amp tumors, overall and in different subtypes, suggesting increased genomic instability. No difference in tumor mutational burden (TMB) between CCNE1 amp and non-amp was found. In primary BC (n=1,385), a higher proportion of TP53 alterations was found in cases with CCNE1 amp (odds ratio [OR] 6.0, 95% confidence interval [CI] 2.5-16.6, q< 0.001). Conversely, CCNE1 amp was mutually exclusive with CDH1 alterations (q< 0.001). Comparable results were found in the analysis of post-treatment/metastatic samples (n=2,368). A subset analysis on HR+/HER2- BCs confirmed that TP53 (OR 4.2, 95%CI 2.28-8.11, q< 0.001) and CDH1 (OR 0.09, 95%CI 0.002-0.57, q< 0.1) alterations co-occurred and were mutually exclusive, respectively, with CCNE1 amp. ARID2 alterations were also enriched in HR+/HER2- tumors harboring CCNE1 amp (OR 10.6, 95%CI 2.54-33.93, q< 0.1). CCNE1 amp was significantly associated with reduced median PFS (8.8 vs 15.2 months in CCNE1 amp [n=9] vs CCNE1 non-amp [n=402]; hazard ratio [HR] 2.82, 95% CI 1.38-5.75, p=0.004) on first line treatment with CDK4/6 inhibitor plus endocrine therapy (ET) in HR+/HER2- metastatic BCs, regardless of the ET partner, FGA and TMB. CCNE1 amp was also associated with numerically inferior median PFS (7.3 vs 20.8 months in CCNE1 amp [n=5] vs CCNE1 non-amp [n=106]; HR 3.1, 95% CI 1.24-7.87, p=0.01) on first line trastuzumab/pertuzumab/taxane treatment in HER2+ metastatic BCs, with a trend toward significance after adjusting for FGA and TMB (p=0.09). Conclusions: CCNE1 amp is associated with specific clinicopathological and genomic features in BCs and linked to an increased genomic instability. CCNE1 amp defines a subset of metastatic BCs with marked poor clinical response to available standard-of-care treatments. Further studies testing novel therapeutic approaches, including synthetic lethality-based strategies targeting CCNE1 amp and CDK2-selective inhibition, are warranted.

Abstract
Abstract
Background Clonal Hematopoiesis (CH) is a well-established risk factor for adverse clinical outcomes including all-cause mortality, cardiovascular disease, and progression to hematologic malignancies. The presence of CH has been shown to adversely impact overall survival in non-hematologic cancers, however whether CH modulates response to specific therapies in breast cancer is not known. Here we investigate the impact of CH mutations on disease progression in patients with metastatic estrogen receptor (ER) positive breast cancer undergoing treatment with first line CDK4/6 inhibitors and endocrine therapy (CDK4/6i+ET). Methods We analyzed data from a well annotated cohort of patients with ER+ breast cancer who received endocrine therapy and CDK4/6 inhibitors. All patients underwent prospective tumor and matched WBC sequencing utilizing the MSK-IMPACT assay. CH variants were detected in blood samples utilizing the well-validated variant detection and filtration pipeline of MSK-IMPACT. CH mutations were defined as putative drivers (CH-PD) or non-putative drivers (CH) as previously described. To ensure the presence of CH at the time of therapy initiation, only patients who had CH sampling performed from 6 months before through 4 months after initiation of CDK4/6i+ET were included. We compared progression free survival (PFS) in patients with and without CH, as well as by CH-PD status and DNMT3A CH mutations. We investigated clinical covariates including type of endocrine therapy, receipt of prior neoadjuvant or adjuvant chemotherapy, and age at start of CDK4/6i+ET. Results The final cohort was comprised of 378 patients, of whom 135 (35.7%) had CH. The median time between sample collection and CDK4/6i+ET initiation was 0 (IQR -0.79 to 0.47 months). Patients with CH were older at time of therapy initiation (median 63.0 versus 54.7 years, p < 0.001). There were no significant differences between groups in terms of endocrine therapy (aromatase inhibitor or fulvestrant), prior chemotherapy, and time from CH sample collection to CDK4/6i+ET start. Univariate Cox-proportional hazard analysis did not reveal a difference between progression free survival and overall CH (HR 0.96, 95% CI 0.75 – 1.23, p = 0.76), CH-PD (HR 1.05, 0.77 – 1.43, p = 0.77), or DNMT3A mutations (HR 1.12, 0.80 – 1.60, p = 0.52) compared to patients without CH. Interestingly, age less than 60 years was found to be associated with PFS outcome (univariate HR 1.57, 1.22 – 2.01, p = 0.0004). Multivariate analysis adjusted for endocrine therapy partner and age at CDK4/6i+ET therapy did not reveal an association between outcome and overall CH (HR 1.07, 0.83 – 1.39, p = 0.59). In patients younger than age 60, presence of overall CH did not confer a significant PFS difference (HR 0.90, 0.63 – 1.29, p = 0.57). In the subset of patients older than 60 (n = 168) presence of CH conferred numerically, but not statistically, significant shorter PFS (HR 1.41 [0.96 – 2.09], p = 0.08). In this population, CH-PD conferred a shorter PFS (HR 1.75, 1.12 – 2.72, p = 0.02). Conclusion We found that CH, CH-PD and DNMT3A CH mutations did not affect PFS among metastatic ER+ breast cancer patients treated with first line CDK4/6 inhibitors. Younger age was associated with increased risk of progression, warranting further investigation. In the subset of patients with age older than 60, CH-PD conferred a shorter PFS. Further data, incorporating records of dose reductions, will be presented at the meeting.

Abstract
Hormone receptor-positive (HR+) breast cancer (BC) accounts for approximately 70% of all breast invasive tumors. Endocrine therapy (ET) represents the standard treatment for HR + BC. Most patients, however, eventually develop resistance to ET, which limits their effectiveness and poses a major challenge for the management of HR + BC. Several mechanisms that contribute to ET resistance have been described. One of the most common mechanisms is the upregulation of alternative signaling pathways that can bypass estrogen dependency, such as activation of the PI3K/Akt/mTOR as well as mitogen-activated protein kinase (MAPK) and the insulin-like growth factor 1 receptor (IGF-1R) pathways. Another common mechanism of endocrine resistance is the acquisition of activating mutations of ESR1, which encodes for the estrogen receptor, that lead to structural changes of the receptor, prevent the binding to anti-estrogen drugs and result in constitutive activation of the receptor, even in the absence of estrogens. Epigenetic changes, such as DNA methylation and histone modifications, can also contribute to ET resistance by altering the expression of genes that are involved in estrogen signaling. Understanding the mechanisms of resistance to ET is crucial for the development of new therapies that can overcome resistance and improve outcomes for patients with HR + BC.

Abstract
Overexpression of human epidermal growth factor receptor 2 (HER2), a transmembrane tyrosine kinase receptor, has been described in about 15-20% of breast cancer (BC) and is associated with poor outcomes. Trastuzumab is the first anti-HER2 monoclonal antibody (mAB) that blocks receptor activity but it also activates immune response against cancer cells, thus, revolutionizing the prognosis of patients with HER2-positive BC. Over the years, new therapies have been developed, including other mAbs and tyrosine kinase inhibitors (TKIs) that required multimodal approaches with chemotherapy to optimize their anticancer activity. This chapter gives a comprehensive overview of the last advancements including new approaches and future combinations, which seem to be very promising in overcoming resistance to the traditional anti-HER2 treatments. A modern therapeutic algorithm should include treatment options based on tumour patterns and a patient-centred approach. A proper patient's selection is crucial to derive maximal benefits from a treatment strategy and emerging biomarkers should be integrated along with the HER2 status, which is currently the only validated biomarker in the context of HER2-positive disease. These biomarkers might include molecular features with reported prognostic/predictive significance, such as phosphatidylinositol 3' -kinase (PI3K) or mitogen-activated protein kinase (MAPK) pathways, programmed cell death protein ligand 1 (PD-L1), and tumour-infiltrating lymphocytes (TILs), which all affect prognosis and response to treatments.

Abstract
Brain metastases (BM) significantly affect the prognosis as well as the quality of life of breast cancer (BC) patients. Although advancements in neurosurgical and radiotherapy techniques improve local control and symptom management, BM remains associated with a poor prognosis. In addition, the efficacy of currently approved systemic therapies in central nervous system (CNS) compartment is still limited, especially after progression on local therapy. The blood-brain barrier (BBB) has been recognized as a mechanism of primary resistance to many chemotherapeutic agents and targeted therapies due to low drug penetration. Other mechanisms of primary and secondary resistance are still unclear and may vary across the BC subtypes. New small molecules have demonstrated efficacy in BM, in particular for the HER2-positive subtype, with a benefit in survival. A new era has begun in the field of BM, and many trials specifically designed for this population are currently ongoing. The BC research community needs to address this call with the final aim of improving the efficacy of systemic therapy in CNS compartment and ultimately preventing the occurrence of BM.

Abstract
PURPOSE OF REVIEW Triple-negative breast cancer (TNBC) has been conventionally associated with poor prognosis, as a result of limited therapeutic options. In the early setting, prognosis is informed by clinical-pathological factors; for patients receiving neoadjuvant treatments, pathological complete response (pCR) is the strongest factor. In this review, we mapped the landscape of clinical trials in the postneoadjuvant space, and identified three patterns of clinical trial design. RECENT FINDINGS For patients at higher risk, effective postneoadjuvant treatments are of paramount importance to address a high clinical need. Postneoadjuvant risk-adapted treatments have demonstrated to improve survival in patients at high of recurrence. SUMMARY Patients at high risk have indication for adjuvant treatment intensification, informed by baseline clinical, pathological or molecular factors (type 1 approach), on the presence, extent and molecular characteristics of the residual disease at the time of surgery (type 2) or on risk factors assessed in the postsurgical setting (type 3), for example, circulating tumour DNA. Most of the past trials were based on type 2 approaches, for example, with capecitabine and Olaparib. Few trials were based on a type 1 approach, notably pembrolizumab for early TNBC. The clinical validity of type 3 approaches is under investigation in several ongoing trials.

Abstract
Loss of HER2 in previously HER2-positive breast tumors is not rare, occurring in up to 50% of breast cancers; however, clinical research and practice underestimate this issue. Many studies have reported the loss of HER2 after neoadjuvant therapy and at metastatic relapse and identified clinicopathological variables more frequently associated with this event. Nevertheless, the biological mechanisms underlying HER2 loss are still poorly understood. HER2 downregulation, intratumoral heterogeneity, clonal selection, and true subtype switch have been suggested as potential causes of HER2 loss, but translational studies specifically investigating the biology behind HER2 loss are virtually absent. On the other side, technical pitfalls may justify HER2 loss in some of these samples. The best treatment strategy for patients with HER2 loss is currently unknown. Considering the prevalence of this phenomenon and its apparent correlation with worse outcomes, we believe that correlative studies specifically addressing HER2 loss are warranted.

Abstract
Targeting the HER2 oncogene represents one of the greatest advances in the treatment of breast cancer. HER2 is one member of the ERBB-receptor family, which includes EGFR (HER1), HER3 and HER4. In the presence or absence of underling genomic aberrations such as mutations or amplification events, intricate interactions between these proteins on the cell membrane lead to downstream signaling that encourages cancer growth and proliferation. In this Review, we contextualize efforts to pharmacologically target the ErbB receptor family beyond HER2, with a focus on EGFR and HER3. Preclinical and clinical efforts are synthesized. We discuss successes and failures of this approach to date, summarize lessons learned, and propose a way forward that invokes new therapeutic modalities such as antibody drug conjugates (ADCs), combination strategies, and patient selection through rational biomarkers.

Abstract
The estrogen receptor (ER) is an important driver in the proliferation, tumorigenesis, and progression of breast cancers, and targeting ER signaling at different levels is a successful strategy in the control of hormone receptor positive (HR+) breast cancer. Endocrine therapy has been the treatment of choice for HR+ breast cancer in the early and advanced stages with multiple agents, including selective estrogen receptor modulators (SERMS), selective estrogen receptor degraders (SERDs), and aromatase inhibitors (AIs), which vary in their mechanisms of action and pharmacokinetics. Combination strategies also employ cyclin dependent kinase 4 and 6 and phosphatidylinositol 3-kinase to maximize the benefits of endocrine therapy. This paper reviews the clinical development of SERDs and other novel ER inhibitors, as well as combination strategies to overcome mechanisms of ER pathway escape. It also assesses the advantages of newer oral ER inhibitors with increased bioavailability, improved therapeutic index, better administration, and increased efficacy, as well as discussing future directions in the field.

Abstract
1010 Background: We recently reported inferior outcomes to CDK4/6 inhibitors and endocrine therapy (CDK4/6i-ET) associated with germline BRCA2 (g BRCA2) in a cohort of estrogen receptor (ER) positive breast cancers. Co-occurrence of gBRCA2 with loss of heterozygosity (LOH) of neighboring RB1 was found to portend particularly poor outcomes. Here, we sought to define the effects of pre-treatment RB1 allelic copy number status on outcomes of CDK4/6i-ET and the likelihood of developing RB1 loss-of-function (LOF) mutations on CDK4/6i through the analysis of an expanded cohort of metastatic ER+ breast cancer patients. Methods: Patients who underwent sequencing on MSK-IMPACT from April 2014 to May 2021 were included. For every sample preceding CDK4/6i-ET, we performed FACETS to infer RB1 allele specific copy number, ploidy, tumor purity and fraction genome altered (FGA). Patients were categorized based on RB1 allelic status: HetLoss (total of one allelic copy), copy neutral LOH (CNLOH), other allelic imbalance including all other aneuploidy states, and diploid. Progression free survival (PFS) was assessed using univariate and multivariate Cox proportional hazard models adjusted for ET partner and FGA. Firth penalized logistic regression was used to study association of pre-treatment RB1 status with acquired RB1 LOF variants in paired post-CDK4/6i samples. Results: Of 2,630 potentially eligible patients, 279 patients had genomic sequencing performed prior to 1st line CDK4/6i-ET. Of these, 75 (26.8%) exhibited RB1 HetLoss, 39 (14.0%) had CNLOH of RB1, 111 (39.7%) exhibited diploid RB1 state, while 54 (19.4%) had other patterns of RB1 allelic imbalance. All non-diploid RB1 states were associated with significantly shortened PFS relative to diploid (univariate HetLoss HR: 2.05, 95% CI: 1.42, 2.97; CNLOH HR: 2.08, 95% CI: 1.32, 3.25; other imbalance HR: 1.70, 95% CI: 1.11, 2.58). Only HetLoss remained significant when adjusted for FGA (HR 1.61, 95% CI: 1.09, 2.38, p = 0.017). RB1 LOF was rare in pre-CDK4/6i tumors (< 1%); excluding these cases did not change our results. Of the 176 patients with paired pre- and post-CDK4/6i samples, only RB1 HetLoss in pre-CDK4/6i sample was significantly associated with development of RB1 LOF mutations in post-CDK4/6i sample (18.4%) as compared to diploid (4.2%, OR 4.25, 95% CI 1.02, 17.7, p = 0.047). These results indicate that tumors with one functional copy of RB1 are more likely to acquire RB1 LOF on CDK4/6i to achieve biallelic RB1 loss as a mechanism of CDK4/6i resistance. Conclusions: We demonstrate that LOH and allelic imbalance of RB1 are associated with shorter PFS on CDK4/6-ET. We postulate this may occur partly as a result of more frequent acquired RB1 LOF mutations under selective pressure of CDK4/6i. These data supports the implementation of more refined allele-specific copy number methods and identifies a high-risk population for escalated monitoring and treatment approaches.

Abstract
The addition of pertuzumab (P) to trastuzumab (H) and neoadjuvant chemotherapy (NAC) has decreased the risk of distant recurrence in early stage HER2-positive breast cancer. The incidence of brain metastases (BM) in patients who achieved pathological complete response (pCR) versus those who do not is unknown. In this study, we sought the incidence of BM in patients receiving HP-containing NAC as well as survival outcome. We reviewed the medical records of 526 early stage HER2-positive patients treated with an HP-based regimen at Memorial Sloan Kettering Cancer Center (MSKCC), between September 1, 2013 to November 1, 2019. The primary endpoint was to estimate the cumulative incidence of BM in pCR versus non-pCR patients; secondary endpoints included disease free-survival (DFS) and overall survival (OS). After a median follow-up of 3.2 years, 7 out of 286 patients with pCR had a BM while 5 out of 240 non-pCR patients had a BM. The 3-year DFS was significantly higher in the pCR group compared to non-pCR group (95% vs 91 %, p = 0.03) and the same trend was observed for overall survival. In our cohort, despite the better survival outcomes of patients who achieved pCR, we did not observe appreciable differences in the incidence of BM by pCR/non-pCR status. This finding suggests that the BM incidence could not be associated with pCR. Future trials with new small molecules able to cross the blood brain barrier should use more specific biomarkers rather than pCR for patients' selection.

Abstract
Abstract
Background: Patients with early HER2-positive breast cancer (BC) and residual disease after HER2-targeted neoadjuvant chemotherapy (NAC) are at high risk of recurrence. It is estimated that 10-30% of HER2-positive breast cancers change HER2 status after trastuzumab alone, but the effects of adding pertuzumab on this phenomenon and clinical outcomes remain unclear. We previously reported a high rate (~50%) of HER2 status change after HP in a small subset of patients. Herein, we present an updated analysis incorporating pathological review of additional cases.Methods: We identified patients with HER2-positive BC who received NAC with pertuzumab and trastuzumab (NAC-HP) followed by surgery at our institution between September 1, 2013 to November 1, 2019. Patients with HER2 status performed either at MSKCC or outside institutions were included. Change in HER2 status on residual disease from baseline was evaluated. We defined HER2 positivity as immunohistochemistry (IHC) IHC3+ or IHC0-2+ FISH amplified (ratio ≥ 2 or ratio < 2 and HER2 copy number ≥ 6 signals/cell). HER2-low was defined as IHC 1+ or 2+, FISH non-amplified. Disease free survival (DFS) and overall survival (OS) were analyzed using the Kaplan-Meier method. Differences between patients with concordant and discordance HER2 status were assessed using the log-rank test.Results: Of 525 patients receiving NAC with HP, 229 (44%) patients had residual disease post NAC-HP. Among these 229 patients, 141 had both pre and post NAC-HP HER2 status available and were included in this analysis. HER2 status on biopsy specimens was determined at MSKCC in 35/141 (25%) and at external institution in 106/141 (75%). The majority of patients (84%) received dose-dense AC-THP; the remainder received TCHP or other HP-based regimens. Most (96%) of patients continued HP after surgery, and 2 patients received T-DM1. Of the 141 patients, 84/141(60%) were found to be HER2 concordant, while 57 (40%) were found to be HER2 discordant. In 13/57 (23%) patients, HER2 expression was lost (IHC 0), while in 44/57 (77%) patients, HER2-low profile was detected (IHC 1+ in 31, and IHC 2+, FISH non-amplified in 13). Further details are reported in the table. Patients with HER2 discordance after NAC-HP had similar survival outcome compared with patients who remained HER2 concordant (5-years DFS: 92.3% versus 88.7%, p=0.49 and 5-yr OS 93.6% versus 88.4%, p=0.70).Conclusions: In a single center cohort, discordant HER2 status after NAC-HP appeared frequently without statistically significant impact on survival outcome, although this finding may be due to the small size and hence low statistical power. Of these, HER2-low profile is the most frequent post treatment HER2 status change. This raises the possibility that patients with change in HER2 status may have heterogenous expression of HER2 at baseline, and HER2-loss or low sub-clones survive as residual disease due to the selection pressure of HP. Alternatively, anti-HER2 therapy may suppress HER2 expression in surviving cells. These findings could inform studies of tailored approaches in the post-neoadjuvant setting based on the biological profile of residual disease.

Abstract
Abstract
Background: Germline genetic alterations are established mediators of breast carcinogenesis, often giving rise to specific forms of genomic instability. BRCA1/2 pathogenic variants (PVs) are emblematic of this phenomenon through their induction of homologous recombination deficiency. While specific patterns of genomic instability may sensitize cancers to therapies such as PARP inhibitors (PARPi) or platinum chemotherapy, their implications for lineage-directed therapies such as endocrine therapy (ET) or CDK4/6 inhibitors (CDK4/6i) are unknown. Herein, we systematically investigated the patterns of association of germline alterations with specific somatic alterations and explored the resulting effect on clinical outcomes. Methods: Patients who underwent germline and matched tumor tissue sequencing utilizing MSK-IMPACT from April 2014 to May 2021 and had available germline analysis results were included. The final analysis presented at SABCS will include 6000 tumors from 5,150 patients, anonymized according to established institutional IRB guidelines to allow for germline analysis on the full cohort. We analyzed genomic data to inform the full spectrum of somatic and germline mutations, ploidy, and allele-specific copy number to determine loss of heterozygosity (LOH). We performed gene- and pathway-level enrichment analyses between somatic variants and germline PVs. Univariable and multivariable Cox proportional hazards models were constructed to assess the association of therapy-specific progression-free survival (PFS) with select germline PVs and germline-somatic interactions. Results: The preliminary analysis includes 2,798 tumors from 2,242 patients with germline and somatic sequencing results. The most frequent germline PVs were: BRCA2 (n = 81), BRCA1 (n = 67), CHEK2 (n = 57), ATM (n = 32), PALB2 (n = 19). The cohort robustly confirmed previously established relationships such as mutual exclusivity of gATM and TP53 variants (OR 0.10, 95% CI 0.032 - 0.33, q = 0.005). Alterations of TP53 were seen in 83% (56/67) of gBRCA1 patients; however, this did not achieve significance when adjusted for receptor subtype (OR 3.90, 95% CI 1.34-11.38, q = 0.15). The size of the cohort allowed discovery of several novel relationships. For instance, gBRCA2 loss was associated with alterations in TGF-B pathway components (OR 3.58, 95% CI 1.70 - 7.56, q = 0.002), potentially relevant to metastatic disease progression. PIK3CA mutations were significantly less prevalent in both gBRCA2 (OR 0.52, 95% CI 0.31 - 0.87, q = 0.063) and gBRCA1 PVs (OR 0.21, 95% CI 0.085 - 0.51, q = 0.014). Our analysis uncovered a strong association between gBRCA2 and somatic RB1 pathogenic alterations (OR 3.58, 95% CI 1.70 - 7.56, q = 0.011), with most variants (80%) encountered in metastatic gBRCA2 tumors. Given the essential role of RB1 in CDK4/6i response, we investigated the effect of BRCA2 status on clinical efficacy of CDK4/6i-ET. Strikingly, gBRCA2 PVs were significantly associated with inferior PFS (HR 2.17, 95% CI 1.46-3.22, p < 0.001) on first line treatment with CDK4/6i-ET. We posited the enrichment of somatic RB1 loss as a potential mechanism of resistance to CDK4/6i. Given the proximity of RB1 to BRCA2 on chromosome 13, we hypothesized that co-LOH of BRCA2 and RB1 predisposes the cancer cells to bi-allelic loss under therapeutic pressure of CDK4/6i. Indeed, 18/26 gBRCA2 (69.2%) tumors evaluable for allele-specific copy number had evidence of RB1 LOH. Discussion: Analysis of germline-somatic interactions yielded novel associations relevant to breast cancer progression and treatment resistance. Among these, we demonstrated BRCA2 carriers to have inferior outcomes to first line CDK4/6i-ET with potential implications for optimal first line therapy and sequencing of CDK4/6i vs PARPi in this patient population.

Abstract
Abstract
Background: Oncogenic mutations involving PIK3CA gene (PI3Kα) are observed in over 40% of patients with hormone receptor-positive (HR+) advanced breast cancer (ABC). Clinical efficacy of PI3K inhibition was demonstrated in a recent trial, but data on the natural history of disease by PIK3CA status are limited in ABC. We assessed patient and disease characteristics, treatment patterns, and clinical outcomes among patients with ABC treated at the Memorial Sloan Kettering Cancer Center in the United States, prior to the clinical availability of alpelisib (a PI3Kα inhibitor). Methods: A retrospective medical record review of adult patients diagnosed with HR+ and human epidermal growth factor receptor 2-negative (HER2-) ABC between January 2014 and December 2018 was conducted. Data collection is ongoing and updated results will be presented. Cohorts were determined by eligible patients’ PIK3CA gene status (i.e., mutant or wild-type [WT]), and were frequency matched to have an equal distribution of the year of ABC diagnosis between cohorts. Study measures were descriptively summarized, and the Kaplan-Meier method was used to estimate progression-free survival (PFS) and left truncation-adjusted overall survival (OS), in months. To assess the association of PIK3CA mutation status on OS, a multivariate Cox proportional hazard model adjusted for age, race, stage at diagnosis, menopausal status, visceral disease, bone only disease, and Charlson Comorbidity Index score was computed. Additional adjustment on treatment modalities is planned. Results: Data for 249 PIK3CA-mutant and 143 PIK3CA-WT patients was analyzed. For the mutant cohort, the mean (SD) age was 59.0 (11.2) years, 80.7% were White, 30.9% were diagnosed with de novo ABC, and 54.6% were postmenopausal at initial BC diagnosis. Visceral- and bone only-disease were observed among 41.4% and 21.7% of patients, respectively. Among patients with a single PIK3CA mutation (n=220, 88.4%), the most common mutations were H1047R (37.3%), E545K (20.5%), and E542K (12.7%). Multiple PIK3CA mutations were observed in 29 (11.6%) patients. For the WT cohort, the mean (SD) age was 56.3 (12.1) years, 77.6% were White, 39.9% were diagnosed with de novo ABC, and 45.5% were postmenopausal at initial BC diagnosis. Visceral- and bone-only disease were observed among 51.8% and 16.8% of patients, respectively. Most common 1st-line treatments for ABC were cyclin-dependent kinase 4 and 6 inhibitor (CDK4/6i) + aromatase inhibitor (AI) (mutant: 38.6%; WT: 40.6%), AI only (mutant: 21.3%; WT:22.4%), CDK4/6i + fulvestrant (mutant: 15.7%; WT: 7.7%), and chemotherapy-based regimens (mutant: 9.6%; WT: 11.2%). Chemotherapy-based regimens were the most common 2nd- (mutant: 25.6%; WT: 21.3%) and 3rd-line (mutant: 41.4%; WT: 33.9%) therapies for both cohorts. Results for PFS and OS are presented in Table 1, and the survival risk was similar for both cohorts (adjusted HR: 1.18, 95% CI: 0.88-1.60). Conclusion: In this preliminary analysis of HR+/HER2- ABC, CDK4/6i-based regimens were the most common 1st-line therapy, and PFS to 1st-3rd line therapies and OS were not statistically significantly different. The recent availability of PI3K inhibitor therapy may improve clinical outcomes among patients with PIK3CA-mutant tumors.

Abstract
Background:The introduction of anti-HER2 therapies, trastuzumab and pertuzumab (HP) to the treatment of metastatic HER2-positive breast cancer has had a transformational impact on the outcomes for this disease. Nevertheless, disease progression is ultimately observed in most patients within 3 years carrying the potential for morbidity and potentially more toxic therapies. To identify selective strategies to prevent disease progression, we sought to elucidate mechanisms of resistance to anti-HER2 therapies by analyzing a large cohort of genomically and clinically annotated HER2+ breast cancers. Methods: Patients with advanced HER2+ breast cancer who underwent prospective clinical tumor sequencing utilizing MSK-IMPACT assay between April 2014 and February 2021 were included in the analysis. Clinical HER2 positivity was defined as per ASCO/CAP guidelines. Cox proportional hazard models were used to determine the association between genomic alterations and progression-free survival (PFS) on 1st line HP and taxane-based therapy (THP). Only patients with a sequenced pre-treatment tumor sample were included in the survival analysis. Recurrent mutations identified were modeled in HER2+ breast cancer cell lines using short hairpin RNAs and CRISPR/Cas9, and the sensitivity of these isogenic pairs to HER2-targeted therapies was evaluated via metabolic and colony formation assays of cell proliferation. Results: We identified 733 ERBB2-amplified primary (n=385) and metastatic (n=348) that underwent sequencing. Concurrent PIK3CA mutations were identified in 30% of the tumors. Pathogenic activating alterations involving the MAPK pathway were observed in 12.8% of tumors with the most frequent alterations being NF1 loss, ERBB2 and RAS activating mutations. MAPK alterations were significantly enriched in the metastatic tumors (16.6%) compared to the treatment-naïve primaries (9.8%, p=0.020). The outcome analysis included 145 patients with advanced clinically HER2+ breast cancer whose tumors were sequenced prior to starting 1st line THP. Twenty percent (29/145) of tumors did not show genomic ERBB2 amplification as detected by NGS and had a significantly worse outcome (median PFS of 9.4 months [95% CI 5.5-19] and 23 months [95% CI 17-30], respectively; p=0.015). PIK3CA mutations were also associated with a shorter PFS (mutant: 13 months [95%CI: 7.7-18] vs wild type: 23 months [95%CI 17-16], p=0.0013). We further found reduced PFS in MAPK altered tumors (median PFS 9.9 months; 95% CI: 5.5-17) compared to the rest of the population (median PFS 21 months; 95% CI: 17-30; p=0.01). On multivariable analysis adjusted for estrogen receptor status, and presence of PIK3CA/AKT1/PTEN mutations and genomic ERBB2 amplification, MAPK pathway alterations were independently associated with worse outcome (HR: 2.25; 95% CI: 1.29, 3.93; multivariate p = 0.0043). To establish a causal role for MAPK alterations in reducing efficacy of anti-HER2 therapy, we depleted NF1 expression or expressed mutant KRAS or BRAF in a panel of HER2+ breast cancer cell lines. Consistently, MAPK-altered cell lines exhibited resistance to FDA approved HER2 inhibitors in vitro and in vivo. Conclusions: This clinicogenomic analysis of mechanisms of resistance to anti-HER2 therapy demonstrated that PIK3CA activating mutations and lack of genomic ERBB2 amplification as detected by tumor sequencing are associated with shortened PFS on HP-based therapy. Our analysis uniquely identified MAPK pathway alterations as additional potential drivers of resistance to anti-HER2 therapy. Inhibition of the PI3K or MAPK pathway in such tumors may represent a new therapeutic strategy to extend H/P benefit.

Abstract
Inhibition of HER2 in HER2-amplified breast cancer has been remarkably successful clinically, as demonstrated by the efficacy of HER-kinase inhibitors and HER2-antibody treatments. Whilst resistance to HER2 inhibition is common in the metastatic setting, the specific programs downstream of HER2 driving resistance are not established. Through genomic profiling of 733 HER2-amplified breast cancers, we identify enrichment of somatic alterations that promote MEK/ERK signaling in metastatic tumors with shortened progression-free survival on anti-HER2 therapy. These mutations, including NF1 loss and ERBB2 activating mutations, are sufficient to mediate resistance to FDA-approved HER2 kinase inhibitors including tucatinib and neratinib. Moreover, resistant tumors lose AKT dependence while undergoing a dramatic sensitization to MEK/ERK inhibition. Mechanistically, this driver pathway switch is a result of MEK-dependent activation of CDK2 kinase. These results establish genetic activation of MAPK as a recurrent mechanism of anti-HER2 therapy resistance that may be effectively combated with MEK/ERK inhibitors.

Abstract
The development of anti-HER2 agents has been one of the most meaningful advancements in the management of metastatic breast cancer, significantly improving survival outcomes. Despite the efficacy of anti-HER2 monoclonal antibodies, concurrent chemotherapy is still needed to maximize response. Antibody-drug conjugates (ADCs) are a class of therapeutics that combines an antigen-specific antibody backbone with a potent cytotoxic payload, resulting in an improved therapeutic index. Two anti-HER2 ADCs have been approved by the FDA with different indications in HER2-positive breast cancer. Ado-trastuzumab emtansine (T-DM1) was the first-in-class HER2-targeting ADC, initially approved in 2013 for metastatic patients who previously received trastuzumab and a taxane, and the label was expanded in 2019 to include adjuvant treatment of high-risk patients with residual disease after neoadjuvant taxane and trastuzumab-based therapy. In 2020, trastuzumab deruxtecan (T-DXd) was the second approved ADC for patients who had received at least 2 lines of anti-HER2-based therapy in the metastatic setting. The success of these two agents has transformed the treatment of HER2-positive breast cancer and has re-energized the field of ADC development. Given their advanced pharmaceutical properties, next-generation HER2-targeted ADCs have the potential to be active beyond traditional HER2-positive breast cancer and may be effective in cells with low expression of HER2 or ERBB2 mutations, opening a spectrum of new possible clinical applications. Ongoing challenges include improving target-specificity, optimizing the toxicity profile, and identifying biomarkers for patient selection. The aim of this review is to summarize the principal molecular, clinical, and safety characteristics of approved and experimental anti-HER2 ADCs, contextualizing the current and future landscape of drug development.

Abstract
PURPOSE Breast cancer (BC) is a leading cause of morbidity, disability, and mortality in women, worldwide; triple-negative BC (TNBC) is a subtype traditionally associated with poorer prognosis. TNBC special histology subtypes present distinct clinical and molecular features and sensitivity to antineoplastic treatments. However, no consensus has been defined on the best adjuvant therapy. The aim of the review is to study the evidence from literature to inform the choice of adjuvant treatments in this setting. METHODS We systematically searched literature assessing the benefit of adjuvant chemotherapy in patients with TNBC special histotypes (PROSPERO: CRD42020153818). RESULTS We screened 6404 records (15 included). All the studies estimated the benefit of different chemotherapy regimens, in retrospective cohorts (median size: 69 patients (range min-max: 17-5142); median follow-up: 51 months (range: 21-268); mostly in Europe and USA). In patients with early-stage adenoid cystic TNBC, a marginal role of chemotherapy was reported. Similar for apocrine TNBC. Medullary tumors exhibited an intrinsic good prognosis with a limited role of chemotherapy, suggested to be modulated by the presence of tumor-infiltrating lymphocytes. A significant impact of chemotherapy on the overall survival was estimated in patients with metaplastic TNBC. Limitations were related to the retrospective design of all the studies and heterogeneous treatments received by the patients. CONCLUSIONS There is potential opportunity to consider treatment de-escalation and less intense therapies in some patients with early, special histology-type TNBC. International efforts are indispensable to validate prospective clinical decision models.

Abstract
e12614 Background: Combination of HP with NAC in the neoadjuvant setting leads to an high rate of pathological complete response (pCR) in patients with stage II-III HER2+ breast cancer (BC). The rate of change in HER2-status after NAC reported in literature is between 10-30%, although NAC comprises a various regimens, and the clinical significance of this phenomenon is unclear. Methods: We extracted data on patients with HER2+ BC treated with NAC and HP between September 1, 2013 to November 1, 2019. Only patients with internally verified HER2 status at our center were enrolled. The rate of pCR (ypT0/is ypN0) and the change in HER2 status on residual disease from baseline were evaluated. We used standard definition of HER2 status based on ASCO/CAP guidelines 2018. HER2-low was defined as immunohistochemistry (IHC) 1+ or 2+, FISH non-amplified. Results: Overall, 130 pts were identified. All patients received dose-dense AC-THP, except for 13 patients who received TCHP or other HP-based regimens. The pCR was achieved in 77/130 (59%) of patients and 53/130 (41%) had residual disease. Among 53 patients with residual disease, HER2 status was analyzed in 25 patients and was pending on the remaining patients. In the 25 analyzed patients, 13 had HER2-loss in residual disease. In 4/13 patients, HER2 expression was lost (IHC 0); in 9/13 patients, HER2-low profile was found (IHC 1+ in 6 patients, and IHC 2+, FISH non-amplified in 3). Details on HER2 status change are described in the table below. Conversely, 12/25 had concordant HER2 status after NAC. Conclusions: At single center, the change in HER2 status after NAC with HP appeared frequent. Pathological review of additional cases is ongoing. The clinical significance is still unclear but may open the possibility to investigate tailored approach in post-neoadjuvant setting based on the biological profile of residual disease.

Abstract
PURPOSE The mTOR complex C1 (mTORC1) inhibitor everolimus in combination with the aromatase inhibitor exemestane is an effective treatment for patients with hormone receptor-positive (HR+), HER2-negative (HER2-), advanced breast cancer (HR+/HER2- aBC). However, everolimus can cause hyperglycemia and hyperinsulinemia, which could reactivate the PI3K/protein kinase B (AKT)/mTORC1 pathway and induce tumor resistance to everolimus. EXPERIMENTAL DESIGN We conducted a multicenter, retrospective, Italian study to investigate the impact of baseline and on-treatment (i.e., during first 3 months of therapy) blood glucose levels on progression-free survival (PFS) in patients with HR+/HER2- aBC treated with everolimus-exemestane. RESULTS We evaluated 809 patients with HR+/HER2- aBC treated with everolimus-exemestane as any line of therapy for advanced disease. When evaluated as dichotomous variables, baseline and on-treatment glycemia were not significantly associated with PFS. However, when blood glucose concentration was evaluated as a continuous variable, a multivariable model accounting for clinically relevant patient- and tumor-related variables revealed that both baseline and on-treatment glycemia are associated with PFS, and this association is largely attributable to their interaction. In particular, patients who are normoglycemic at baseline and experience on-treatment diabetes have lower PFS compared with patients who are already hyperglycemic at baseline and experience diabetes during everolimus-exemestane therapy (median PFS, 6.34 vs. 10.32 months; HR, 1.76; 95% confidence interval, 1.15-2.69; P = 0.008). CONCLUSIONS The impact of on-treatment glycemia on the efficacy of everolimus-exemestane therapy in patients with HR+/HER2- aBC depends on baseline glycemia. This study lays the foundations for investigating novel therapeutic approaches to target the glucose/insulin axis in combination with PI3K/AKT/mTORC1 inhibitors in patients with HR+/HER2- aBC.

Abstract
e15147 Background: Peripheral blood parameters, such as neutrophil-to-lymphocyte ratio (NLR), derived neutrophil-to-lymphocyte ratio (dNLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR) and LDH level, have been correlated to immunotherapy (IO) benefit in melanoma and lung cancer. We investigated if peripheral blood parameters could have the same predictive role in a variety of solid tumors treated with either single-agent IO or IO combinations. Methods: Baseline (0 to 14 days from treatment start) blood parameters, including NLR, dNLR, PLR, LMR and LDH, were collected in patients (pts) with metastatic solid tumors treated in phase I trials testing anti-PD-1/PD-L1 single agent (N = 59) and anti-PD-1/PD-L1-based combinations (N = 94), including combinations with immune checkpoint inhibitors/agonists or other agents. IO benefit was assessed for overall survival (OS), progression free survival (PFS), overall response rate (ORR), disease control rate (DCR), and 90-day mortality rate. Logistic regression, Kaplan-Meier method, and Cox regression were carried out to evaluate the impact of clinical and baseline blood parameters on IO efficacy. Results: From Aug2014 to May2019, 153 pts were included [median age 58 (32-80)]. Female/male ratio was 1.47:1 (91 females/62 males). The most common tumors were gastrointestinal, breast, and gynecological cancers (22.9%, 22.2%, and 15.0%, respectively). Sixty pts (39.2%) had received more than two lines of therapy. Overall, ORR, DCR, and 90-day mortality were 11.8%, 34.9%, and 15.7%, respectively. At multivariate analysis, LDH higher than upper limit of normal (ULN) was associated with reduced DCR (LDH ≤ULN vs > ULN: 50.8% vs 20.8%, OR 0.25, 95%CI 0.1-0.62, p = .003) and increased 90-day mortality (LDH ≤ULN vs > ULN: 7.9% vs 24.5%, OR 3.59, 95%CI 1.18-10.9, p = .025). At a median follow-up of 25.9 months (22.3-29.6), 138 pts (90.2%) experienced tumor progression and 117 (77.0%) had died. At multivariate Cox regression analysis, LDH > ULN and dNLR > 3 were independently associated with reduced PFS (LDH > ULN: HR 1.97, 95%CI 1.30-2.99, p < .001; dNLR > 3: HR 2.29, 95%CI 1.39-3.77, p < .001) and reduced OS (LDH > ULN: HR 2.04, 95%CI 1.26-3.28, p = .004; dNLR > 3: HR 2.06, 95%CI 1.12-3.79, p = .02). Conclusions: Our analysis confirms that baseline LDH > ULN and dNLR > 3 are predictive biomarkers for IO efficacy, regardless of tumor type and combinations with other drugs, representing an easy tool that deserves prospective validation in IO-based clinical trials.

Abstract
e12653 Background: The addition of pertuzumab in the neoadjuvant setting has become a standard of care in stage II-III HER2-positive BC. In the Katherine study the incidence of brain metastases (BM) at the follow-up of 3-years was 5.9 % in patients (pts) with residual disease who received TDM1. The aim of this study was to assess the incidence of BM in pts who received NAC with HP at a single center who were found to have pathological complete response (pCR) (ypT0/is ypN0) versus non-pCR at the time of surgery. Methods: Chart review on HER2-positive pts treated with NAC and HP between September 1, 2013 to May 1, 2018 was conducted. Only surgical specimens of pts whose pre-NAC specimens were internally reviewed for HER2 status by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) were included in this analysis. Data on BM as component of distant recurrence along with invasive disease-free (IDFS) and overall survival (OS) were collected. Results: 540 pts were identified. Cases with no internally verified-HER2 status (387), equivocal status (10) and discordant internal assessment (13) were excluded. 130 pts with preoperative HER2 status confirmed by dedicated breast pathologists were included. Clinicopathological features are described in Table. pCR was achieved in 77/130 (60%) of cases, residual disease in 53/130 (40%). The median follow-up was 2.83 (0.35-5.3) years. The rate of BM as first presentation of distant disease was 3.8 % (3/77) and 3.7 % (2/53) in pts with pCR and non-pCR, respectively. Median time to development BM was 35 (13-58) months and 11.7 (9-14) months in the pCR group and non-pCR, respectively. Conclusions: In our cohort, the combination of HP was associated with a high pCR rate. At a median follow-up of 2.8 years, the incidence of BM appeared to be similar in pts who achieved pCR versus non-pCR. The data of IDFS and OS will be reported. Further data are needed to validate our findings before designing clinical trials to test prophylactic strategies to prevent BM. [Table: see text]

Abstract
Introduction: Triptorelin is a luteinizing hormone-releasing hormone analog (LH-RHa) inducing ovarian function suppression (OFS). It is approved by FDA and EMA in association with tamoxifen or aromatase inhibitor (AI) and with fulvestrant and palbociclib in premenopausal women with hormone receptor (HR)-positive breast cancer. Its potential role to preserve ovarian function during chemotherapy has also been recently clarified. Areas covered: Several studies have investigated the role of adding OFS to tamoxifen and aromatase inhibitors as adjuvant treatment in early breast cancer. The addition of triptorelin is not free from adverse events as the combination with tamoxifen and exemestane resulted in an increase of endocrine-deprivation symptoms. Clinical trials have explored the combination of LH-RHa with chemotherapy in fertility preservation, demonstrating no detrimental effect on patients' oncological outcome. This is all discussed in this evaluation. Expert opinion: Triptorelin represents a standard-of-care in premenopausal women with HR-positive breast cancer and in some cases of male breast cancer. In the adjuvant setting, a personalized approach is required to combine LH-RHa with the right partner considering the risk of recurrence and the toxicity profile. LH-RHa may be offered to breast cancer patients in the hope of reducing the likelihood of chemotherapy-induced ovarian insufficiency.

Abstract
Introduction: Despite dramatic improvements in survival achieved with currently available anti-HER2 agents, HER2-positive metastatic breast cancer remains an almost invariably deadly disease, with primary or acquired resistance to HER2-directed agents developing during treatment. Many efforts are focused on identifying new agents that may more effectively inhibit HER2 signaling and on possible combination strategies. Areas covered: This review summarizes the landscape of drugs under development for HER2-positive metastatic breast cancer, as antibody-drug conjugates, monoclonal anti-HER2 antibodies, bispecific antibodies, or novel tyrosine kinase inhibitors. Moreover, available data for possible combination of anti-HER2 drugs and different agents, as immunotherapy, PI3K/mTOR inhibitors, CDK4/6 inhibitors currently under evaluation are reviewed. These strategies may overcome mechanisms of resistance and further improve patient outcomes. Expert opinion: Identification of valuable predictive biomarkers is needed to better inform choice of treatment sequence for the individual patient and limit the financial toxicity of these agents.

Abstract
Cancer drug development is a time and resources consuming process. Around 90% of drugs entering clinical trials fail due to lack of efficacy and/or safety issues, more often after conspicuous research and economic efforts. Part of the discarded drugs might be beneficial only in a subgroup of the study patients, and some adverse events might be prevented by identifying those patients more vulnerable to toxicities. The implementation of pharmacogenomic biomarkers allows the categorization of patients, to predict efficacy and toxicity and to optimize the drug development process. Around seventy FDA approved drugs currently present one or more genetic biomarker to keep in consideration, and with the progress of Precision Medicine tailoring therapies on individuals' genomic landscape promises to become a new standard of cancer care. In the current article we review the role of pharmacogenomics in cancer drug development, underlying the advantages and challenges of their implementation.

Abstract
Triple negative breast cancer (TNBC) represents a heterogeneous subtype of breast cancer characterized by an unfavorable prognosis due to its aggressive biology. The median overall survival (OS) for patients with metastatic TNBC is around 9-12 months with conventional cytotoxic agents. Considering this suboptimal outcome, which is induced despite of medical treatment, new therapeutic strategies would be urgently needed. The ultimate goal of precision medicine is to identify specific molecular alterations that permit considering effective targeted drug(s). Germline BRCA mutations occur in 10-20% of TNBC patients while somatic mutations occur in 3-5% of them. Alterations in the homologous recombination (HR) system are typical of BRCA mutant tumors, but can also be identified in tumors that do not carry this mutation, defining a subgroup of patients referred to as BRCAness. In this review, we focus on the role of homologous recombination deficiency (HRD) as both predictive and prognostic factor in different settings of TNBC patients treated with DNA damaging drugs and poly ADP ribose polymerase (PARP) inhibitors.

Abstract
OBJECTIVES Predictive factors of response to eribulin are lacking. We aimed to investigate the activity and safety of eribulin in a real-world population of metastatic breast cancer (MBC) patients and to identify possible predictive factors of progression-free survival (PFS) and objective response. METHODS We retrospectively analyzed 71 eribulin-treated MBC patients. Best response rate, PFS, and adverse events (AEs) were evaluated. The impact of different clinical-pathological factors on PFS was evaluated using the Cox proportional hazards model. Predictive factors of response were identified by discriminant function analysis (DFA). RESULTS Median PFS was 3.75 months (95% CI, 2.39-4.48); 12 patients (16.90%) achieved partial response (PR), 27 (38.03%) stable disease. The most common AEs were fatigue (25.83%), neutropenia (16.56%), and peripheral neuropathy (13.91%). A worse performance status (p = 0.025) and a higher number of metastatic organ sites (p = 0.011) were associated with a worse PFS under eribulin. Overall, in the DFA-predictive model, neutrophil-to-lymphocyte ratio at baseline, estrogen receptor, Ki67, histology, and age were predictive of PR with 100% accuracy. CONCLUSIONS Activity and safety profiles of eribulin were consistent with literature data. Performance status and number of metastatic sites were predictive factors of PFS. DFA could be a promising tool to discriminate responses to eribulin among MBC patients.

Abstract
RATIONALE Breast cancer is the most common cancer affecting females worldwide and its lifetime risk increases with age. Human epidermal growth factor receptor gene-2 (HER-2) positive breast cancer represents about 20% of all breast cancers, 1 out of 10 is diagnosed in women over 70 years of age. It tends to be more aggressive and to spread more quickly than other subtypes, but the introduction in clinical practice of new anti-HER-2 agents combined with chemotherapy has significantly improved progression free and overall survival. Elderly patients are frequently undertreated because of concerns about their age, performance status, and comorbidities. Here, we report a case of an octogenarian patient treated with T-DM1 with brilliant results. PATIENT CONCERNS An 87 years old woman affected with HER-2 positive breast cancer presented progression of disease with lymph node and skin metastases after 3 lines of chemoimmunotherapy. DIAGNOSES Breast cancer in elderly patient, lymph node, and skin metastases. INTERVENTIONS Chemoimmunotherapy (trastuzumab emtansine). OUTCOME Objective response of the disease and significant clinical benefit. LESSONS This case clearly suggests that age and comorbidities do not always represent an absolute contraindication to combined treatments.

Abstract
e12566 Background: Capecitabine is an active agent in the treatment of advanced breast cancer (ABC). It is commonly administered at the approved dosage of 1250 mg/m2 twice daily for 2 weeks followed by 1 week rest period. Methods: The study population included 162 pts retrospectively analyzed with ABC treated with capecitabine between 2006 and 2015 at our Institute. Capecitabine was given 14 day on,7 day off cycle at a daily dose of 1900 mg/m2, a modified schedule used to minimize side effects. The objective were overall response rate (ORR), median duration of treatment (MDT) progression-free survival (PFS), overall survival (OS). Results: The median age was 64 years (range 33-89). Pts with hormone receptor positive ABC were 133 (82%), 6 (4%) had HER-2 positive disease and 29 (18%) a triple negative profile. One hundred and thirty eight (85%) had already received chemotherapy in adjuvant and/or metastatic setting; anthracycline and taxanes were given in 64 pts (40%), anthracycline in 60 pts (37%) and taxane in 4 pts (2%), 9 pts (6%) received other regimens of chemotherapy. Twenty-five pts (15%) were chemo-naive. One hundred and thirty-three pts (82%) received endocrine therapy. Sixty-four pts (38%) had predominantly non-visceral metastases, 26 pts (16%) exclusive visceral involvement, 72 (44%) exhibited both characteristics. ORR was 58% (CR = 2%, PR = 16% SD = 40%) and MDT was 6.9 months. The median PFS and OS were 6.9 months and 21 months, respectively. We defined as “long responders” 19 pts (12%) with disease control interval > 24 months and, among them, as “very long responders”, 9 pts (6%) who exceeded 36 months. Efficacy was unrelated to biological profiles, sites of metastasis or previous therapies. No grade 3 and 4 adverse events occurred. Conclusions: Our results show that in pts with ABC a lower dose of capecitabine has a good toxicity profile and similar overall response rate and survival data in comparison to the approved dose. In addition, we identified a subset of long and very long responders but further studies are warranted to evaluate clinical/biological predictors of a long-term response.

Abstract
Sorafenib is an oral multikinase inhibitor with anticancer activity against a wide spectrum of cancers. It is currently approved for the treatment of patients with hepatocellular carcinoma, advanced renal cell carcinoma or progressive, locally advanced or metastatic differentiated thyroid carcinoma. In this review, we present a number of studies that investigated the efficacy and safety of sorafenib in these settings. We also discuss the perspectives on the use of this molecule, including the role of sorafenib as comparator for the development of new drugs, the combination of sorafenib with additional therapies (such as transarterial chemoembolization for hepatocellular carcinoma) and the use of this treatment in several other advanced refractory solid tumors.
