    Development of a method for detecting genetic mutations in early breast cancer using Plasma-Safe-SeqS technology and its clinical application. (SABCS 2024)
    In addition to the postoperative blood sampling described above, we are currently conducting (1) postoperative blood sampling and (2) postoperative blood sampling after completion of adjuvant therapy. We aim to ascertain whether this mutation can serve as a predictive marker for response to postoperative chemotherapy or recurrence, especially in hormone-positive breast cancer patients at high risk of recurrence.

    Clinicogenomic landscape and function of PIK3CA, AKT1, and PTEN mutations in breast cancer (SABCS 2024)
    Background The AKT inhibitor capivasertib was recently approved in the 2L+ setting for patients (pts) with hormone receptor-positive metastatic breast cancer with alterations in PIK3CA, AKT1, and/or PTEN...However, one-third of patients have variants beyond E542, E545, and H1047 with less certainty about targetability. The preponderance of rare PIK3CA mutations and co-occurrences between PIK3CA, AKT1, and PTEN with genes outside the PI3K pathway merits functional investigation.

    Tumor genomics in young patients with metastatic breast cancer (SABCS 2024)
    In EMBRACE, differences in mutational frequency of several genes were observed by age at MBC diagnosis among patients with recurrent MBC, most notably for HR+/HER2- patients. Lower OS among younger recurrent MBC patients may be driven by these differences, particularly by high frequency of TP53 mutations in this age group. Further investigation of these genes is warranted to elucidate pathways leading to metastasis and to improve survival for young MBC patients.

    A case of sequential alpelisib and capivasertib in a patient with metastatic breast cancer harboring both a PIK3CA and AKT mutations (SABCS 2024)
    Therapies targeting mutations in this pathway approved in conjunction with endocrine therapy include alpelisib, everolimus and capivasertib...She received nab-paclitaxel/atezolizumab for 4 months, letrozole and abemaciclib for 2 months, letrozole alone for 6 months, and letrozole and ribociclib for 6 weeks. Given presence of PIK3CA mutation, 4th line treatment with fulvestrant and alpelisib was planned...After progressing on capecitabine after 2 months, alpelisib with exemestane was initiated...Due to a low ejection fraction despite work with cardiooncology, she was not a candidate for trastuzumab deruxtecan. She progressed on oral cyclophosphamide and methotrexate after 2 months and Sacituzumab govitecan after 3 months...Comprehensive biomarker assessment is needed to identify patients who may benefit from sequential therapies. There is a need for trials comparing therapies that target the PI3K pathway at distinct points, potential sequencing of these therapies, and the optimal sequence strategy.

    Real-World Molecular Profiling After CDK4/6 Inhibition in Advanced Breast Cancer: Analysis of the SOLTI-1903 HOPE Study (SABCS 2024)
    Over two-thirds of pts progressing on CDK4/6i present with ESCAT I-II level alterations detected via tumor or liquid biopsy. Notably, 15-25% of these pts exhibit cooccurring targetable alterations. In our study, the most frequently targeted alteration was PIK3CA mut, due to lack of approval for targeted therapies for other ESCAT I-II alterations in Spain during the study period.

    Genomic predictors of response among patients with hormone receptor-positive (HR+)/HER2- metastatic breast cancer (MBC) receiving the AKT inhibitor (AKTi) ipatasertib combined w/ endocrine therapy & a CDK4/6 inhibitor (CDK4/6i) in TAKTIC trial (SABCS 2024)
    TAKTIC was a phase Ib open-label trial evaluating ipatasertib in combination with fulvestrant, an aromatase inhibitor, or fulvestrant + palbociclib, in participants with HR+/HER2- MBC who received ≥1 line of prior therapy for MBC and had exposure to CDK4/6i (NCT03959891). Genomic insights using NGS suggest that MBC post-CDK4/6i is more susceptible to an AKTi-based treatment with ipatasertib in the presence of a PI3K/AKT/PTEN pathway mutation, whereas alterations in FGFR1 are associated with worse outcomes. This effort is one of very few studies prospectively evaluating mediators of AKTi response, an area of active interest given changes in the therapeutic landscape. The results presented here are hypothesis-generating; future work is underway to further expand upon these data.

    Prevalence of PIK3CA/AKT1/PTEN and other genomic alterations in primary and recurrent tumor tissue: exploratory analysis from the Phase 3 CAPItello-291 clinical trial (SABCS 2024)
    Background Based on the positive results from the CAPItello-291 trial, capivasertib plus fulvestrant is a treatment option for adult patients with HR+/HER2− locally advanced or metastatic breast cancer who have progressed on an endocrine-based regimen and whose tumors harbor one or more alterations in PIK3CA, AKT1, or PTEN. Consistent with the literature, recurrent tissues were enriched for ESR1, BRCA2, GATA3, CDKN2A, and SMAD4 alterations, indicating a potential role for these gene alterations in driving disease recurrence. The PIK3CA/AKT1/PTEN-altered cohort was enriched for CDH1 mutations while the non-altered cohort was enriched for alterations in cell cycle-related genes previously associated with endocrine and cyclin-dependent kinase 4/6 inhibitor resistance.

    Predicting response to capivasertib in AKT1 mutant advanced breast cancer (SABCS 2024)
    Allelic imbalance at the AKT1 locus and clonal dominance of the AKT1 mutation were associated with progression free survival (PFS) in plasmaMATCH Cohorts C (capivasertib plus fulvestrant) and D (capivasertib alone) combined. Breast cancers with mutations in AKT1 frequently have allelic imbalance favouring the mutation, resulting in increased expression of mutant transcript. Allelic imbalance of AKT1, and/or clonally dominant AKT1 mutations, were prognostic for significantly greater PFS of patients treated with capivasertib.

    Characterizing the genomic landscape of breast cancer in an Irish cohort of patients (ESMO 2024)
    We present the largest study of BC variant frequencies in a cohort of Irish breast cancer patients to date and confirm NGS is feasible and identifies clinically relevant and actionable variants. We confirm that the frequency of PIK3CA alterations, in addition to codon specificity, are comparable to those observed in European and US cohorts and demonstrate that the detection of clinically relevant biomarkers is not confined to ER positive HER2 negative BC. The tissue failure rate (19%) underscores the need for cfDNA testing to identify the expanding range of actionable targets in BC to improve access to emerging targeted therapies and biomarker-driven clinical trials.

    The study highlights PSH and perifocal oedema's significant effect on olfactory function in OGM patients but finds no link between olfactory impairment and tumour mutations, possibly due to the small sample size. This suggests that age and gender affect olfactory impairment. Additional research with a larger group of participants is needed to explore the impact of OGM driver mutations on olfactory performance.

    The prognosis of patients treated with everolimus for advanced ER-positive, HER2-negative breast cancer is driven by molecular features. (PubMed, J Pathol Clin Res)
    Overall survival was longer in patients with pS6 ≥ 3rd quartile (27.6 versus 19.3 months, p = 0.038) and in patients with any mutation in the PIK3CA/AKT/mTOR pathway (27.6 versus 19.3 months, p = 0.011). The prognosis of patients treated with everolimus for advanced ER-positive, HER2-negative breast cancer appears primarily driven by molecular features associated with the activation of the PIK3CA/AKT/mTOR pathway.

    Capivasertib: A Novel AKT Inhibitor Approved for Hormone-Receptor-Positive, HER-2-Negative Metastatic Breast Cancer. (PubMed, Ann Pharmacother)
    In the phase III CAPItello-291 trial, capivasertib in combination with fulvestrant (C+F) demonstrated improved progression-free survival (PFS) (7.3 vs 3.1 months) compared with placebo-fulvestrant (P+F) cohort in AKT-altered pathway patients who had progressed through prior aromatase inhibitor. Capivasertib is a viable treatment option for patients with PIK3CA/AKT1/PTEN activating mutations following progression on endocrine-based regimens in the metastatic setting or recurrence within 12 months of completing adjuvant therapy. Integration of capivasertib into clinical practice is ongoing; intermittent dosing and favorable toxicity are attractive for future novel combination prospective trials.

    These data suggest that TN-ILC had higher frequency of CDH1, ERBB2, AKT1, ARID1A mutations, higher M2 macrophages and neutrophils and lower M1 macrophages and CD8 T cells infiltration and, lower T cell inflamed signature. High TMB and AR expression can translate into use of immunotherapy (ICI) and AR antagonists in these patients. Additonal analysis to determine the optimal biomarker for ICI response in TN-ILC is needed.

    Genomic Variability Within Intrinsic Subtypes of Advanced Breast Cancer (USCAP 2024)
    There is a great genomic variability in each intrinsic subtype of advanced BC, with apparently no genomic pattern correlating with each phenotype. Although a transcriptomic test (Prosigna) can help in the classification of the tumors, NGS sequencing with an extended panel allows identifying genetic variants that might benefit the patient with a targeted therapy i a significant percentage of cases.

    BMPR1A G298D Point Mutation is a Recurrent Genomic Event in a Subset of Presumably Sex Cord-Stromal Tumors with Ambiguous Features Between Adult and Juvenile Granulosa Cell Tumors (USCAP 2024)
    BMPR1A G298D mutation was exclusively identified in a subset of driverless neoplasms which were classified as granulosa cell tumors (3/27=11%). For BMPR1A-mutant tumors, the overall absence of any detectable known driver mutations supports our hypothesis that this alteration could be an alternative rare tumorigenic mechanism.

    A gain of function mutation in AKT1 increases hexokinase 2 and diminishes oxidative stress in meningioma. (PubMed, Cytokine)
    Treatment with the conventional drug of choice AZD5363 (a pan AKT inhibitor) enhanced cell death and diminished HK2 levels in AKT1 mutants...By affecting metabolism, inflammation, and redox homeostasis AKT1-E17K confers a survival advantage in meningioma cells. Our findings suggest that targeting AKT-HK2 cross-talk to induce ROS-dependent cell death could be exploited as novel therapeutic approach in meningiomas.

    Allosteric PI3K-alpha inhibition overcomes on-target resistance to orthosteric inhibitors mediated by secondary PIK3CA mutations (YIR 2024)
    Background: PIK3CA mutations occur in ~40% of HR-positive breast cancers, where alpelisib, an orthosteric PI3Kα inhibitor, is FDA-approved in combination with fulvestrant... To identify on-target and off-target alterations potentially mediating resistance to PI3Kα inhibitors, we used a targeted next-generation sequencing assay (Guardant360; Guardant Health) to analyze ctDNA in serially collected plasma samples from 32 patients with PIK3CA-mutated advanced HR-positive, HER2-negative breast cancer treated with alpelisib and inavolisib...Some mutations had differential effects on PI3Kaselective vs. pan-PI3K inhibitors, but resistance induced by all mutations could be overcome by the novel allosteric pan-mutant-selective PI3Ka-inhibitor RLY-2608... In one of the largest patient cohorts analyzed to date, this study defines the clinical landscape of acquired resistance to PI3Ka inhibitors. Genomic alterations within the PI3K pathway represent a major mode of resistance and identify a novel class of secondary PIK3CA resistance mutations that can be overcome by an allosteric PI3Ka inhibitor. Together, these findings provide insights to guide strategies to overcome resistance in PIK3CA-mutated cancers.

    Incongruity between T cell receptor recognition of breast cancer hotspot mutations ESR1 Y537S and D538G following exogenous peptide loading versus endogenous antigen processing. (PubMed, Cytotherapy)
    To investigate the basis of this lack of recognition we performed immunopeptidomics analysis of a mutant-overexpressing lymphoblastoid cell line and found that the ESR1 Y537S neopeptide was not endogenously processed, despite binding to HLA-B*40:02 when exogenously pulsed onto the target cell. These results indicate that stimulation of T cells that likely derive from the naïve repertoire with pulsed minimal peptides may lead to the expansion of clones that recognize non-processed peptides, and highlights the importance of using methods that selectively expand T cells with specificity for antigens that are efficiently processed and presented.

    Clinical and genomic landscape of FGFR3-altered urothelial carcinoma and treatment outcomes with erdafitinib: a real-world experience. (PubMed, Clin Cancer Res)
    FGFR3 mutations are common in urothelial carcinoma, whereas FGFR2 alterations are rare. Discordance of FGFR3 mutational status between primary and metastatic tumors occurs frequently and raises concern over sequencing archival primary tumors to guide patient selection for erdafitinib therapy. Erdafitinib responses were typically brief and dosing was limited by toxicity. FGFR3, AKT1, and TP53 mutations detected in cfDNA represent putative mechanisms of acquired erdafitinib resistance.
