: Antibody-drug conjugates (ADCs) represent a novel class of molecules composed of a recombinant monoclonal antibody targeted to a specific cell surface antigen, conjugated to a cytotoxic agent through a cleavable or non-cleavable synthetic linker. The rationale behind the development of ADCs is to overcome the limitations of conventional...

Background: Treatment for HER2-positive (+) metastatic breast cancer has improved in the last decade. We analyzed treatment changes over time and their impact on patients outcomes in a real-world dataset. Methods: Data from 637 HER2+ patients with metastatic breast cancer enrolled in the multicenter Italian GIM14/BIOMETA study were retrieved....

Neoadjuvant chemotherapy (NACT) for breast cancer (BC) increases surgical and conservative surgery chances. However, a significant proportion of patients will not be eligible for conservative surgery following NACT because of large tumor size and/or low chemosensitivity, especially for hormone receptor (HR)-positive/ human epidermal growth...

The treatment of HR+/HER2- metastatic breast cancer with cyclin-dependent kinases 4 and 6 inhibitors combined with endocrine therapy has recently emerged as the most relevant therapeutic strategy. However, in routine clinical practice, the best therapeutic approach in patients with comorbidities at early relapsing or ab initio metastatic...

Dose-dense adjuvant chemotherapy is standard of care in high-risk early breast cancer patients. However, its role in HER2-positive patients is still uncertain. In this exploratory analysis of the GIM2 trial, we investigated the efficacy of dose-dense chemotherapy in HER2-positive breast cancer patients with or without exposure to trastuzumab....

Purpose: The aim of this study was to evaluate the effectiveness of CDK 4/6 inhibitors (CDK 4-6i) according to HER2 status (low/zero), and endocrine resistance/sensitivity, as well as the efficacy of second-line treatments, in a large real-world cohort. Methods: The GIM14/BIOMETA study (NCT02284581) is a retrospective/prospective study of the...

The introduction of PARP inhibitors has revolutionized the management and treatment of patients with pathogenic germline variants of BRCA1/2 who have developed breast cancer. The implementation of PARP inhibitors in clinical settings can be challenging due to their overlapping indications with other drugs, including both recently approved...

T-DM1 improves progression-free survival (PFS) and overall survival (OS) in patients with metastatic human epidermal growth factor receptor 2-positive (HER2+) breast cancer progressing on prior trastuzumab plus a taxane. A paucity of data is available on T-DM1 efficacy after dual anti-HER2 blockade with pertuzumab and trastuzumab plus a taxane,...

Ribociclib plus letrozole demonstrated manageable safety and efficacy profiles in hormone receptor-positive (HR+), human epidermal growth factor receptor-2-negative (HER2-) advanced breast cancer (ABC) in the Phase 3b CompLEEment-1 trial.

Background: Intermediate clinical endpoints (ICEs) are frequently used as primary endpoint in randomised trials (RCTs). We aim to assess whether changes in different ICEs can be used to predict changes in overall survival (OS) in adjuvant breast cancer trials. Methods: Individual patient level data from adjuvant phase III RCTs conducted by the...

Background: Previous analyses of the GIM (Gruppo Italiano Mammella) 2 study showed that addition of fluorouracil to epirubicin, cyclophosphamide, and paclitaxel in patients with node-positive early breast cancer does not improve outcome, whereas dose-dense chemotherapy induces a significant improvement in both disease-free survival and overall...

Background: Prior exposure to adjuvant endocrine therapy (ET) and timing to recurrence are crucial factors for first-line treatment choices in patients with hormone receptor-positive/HER2-negative (HR+/HER2-) breast cancer (BC) and in clinical trial eligibility, classifying metastatic HR+/HER2- BC as endocrine sensitive (ES) or primary...

Purpose: In estrogen receptor-positive (ER+) breast cancer (BC), single-nucleotide polymorphisms (SNPs) in the aromatase gene might affect aromatase inhibitors (AIs) metabolism and efficacy. Here, we assessed the impact of SNPs on prognosis and toxicity of patients receiving adjuvant letrozole. Experimental design: We enrolled 886...

PURPOSE: The mTORC1 inhibitor everolimus (EVE) in combination with the aromatase inhibitor exemestane (EXE) is an effective treatment for patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative, advanced breast cancer (HR+/HER2- aBC). However, EVE can cause hyperglycemia and hyperinsulinemia, which could...
