AURORA aims to study the processes of relapse in metastatic breast cancer (MBC) by performing multi-omics profiling on paired primary tumors and early-course metastases. Among 381 patients (primary tumor metastasis pairs: 252 targeted gene sequencing, 152 RNA 67 single nucleotide polymorphism arrays), we found a driver role for GATA1 MEN1 somatic mutations. Metastases were enriched ESR1, PTEN, CDH1, PIK3CA, RB1 mutations; MDM4 MYC amplifications; ARID1A deletions. An increase clonality was...

Abstract Purpose: To evaluate a triplet regimen combining immune checkpoint blockade, AKT pathway inhibition, and (nab-) paclitaxel as first-line therapy for locally advanced/metastatic triple-negative breast cancer (mTNBC). Patients Methods: The single-arm CO40151 phase Ib study (NCT03800836), the signal-seeking cohort of IPATunity130 (NCT03337724), randomized III IPATunity170 trial (NCT04177108) enrolled patients with previously untreated mTNBC. Triplet comprised intravenous atezolizumab...

Background: To immunohistochemically evaluate the association between presence of cancer-associated fibroblasts (CAFs) and tumour expression podoplanin (PDPN) in head neck squamous cell carcinoma (HNSCC) their with clinicopathological variables.Material Methods: A tissue microarray (TMA) biopsy sections from patients diagnosed HNSCC was stained antibodies against CAFs marker, α-smooth muscle actin (α-SMA), PDPN.We subsequently evaluated to determine them variables including age, primary...

Background: The 21-gene Oncotype DX Breast Recurrence Score® assay is prognostic and predictive of chemotherapy benefit for patients with estrogen receptor-positive, HER2− early breast cancer (EBC). KARMA Dx study evaluated the impact results (RS) on treatment decision EBC high-risk clinicopathological characteristics whom (CT) was considered. Methods: Eligible were candidates if CT considered standard recommendation by local guidelines. Three cohorts predefined: (A) pT1-2, pN0/N1mi, grade...

Background: Patients (pts) with ER+, HER2– early breast cancer (EBC) do not universally benefit from adding adjuvant chemotherapy (CT) to hormonal treatment (HT). The 21-gene Oncotype DX Breast Recurrence Score® (RS) assay is uniquely designed and validated guide CT decisions in this population. Methods: primary objective of the KARMA Dx study was assess impact RS result on recommendations high-risk patients for whom uncertain. Secondary evaluation physicians' confidence their...

Abstract Background: Different approaches for treatment de-escalation are being investigated; however, the current ongoing phase III adjuvant trials with CDK4/6 inhibitors not addressing question if these drugs can replace multi-agent chemotherapy in high-risk early breast cancer. Here, we present primary results of CORALLEEN 2 trial, which evaluates efficacy ribociclib plus endocrine therapy (ET) as neoadjuvant patients Luminal B disease. Methods: is a parallel, multicenter, two-arm,...
