Breast surgery after neoadjuvant therapy
Purpose of review The standard of care in breast surgery has changed, from mastectomy to breast conserving surgery whenever possible, and from axillary dissection to sentinel node biopsy. Neoadjuvant systemic approaches have broadened the indications for organ-conserving and less mutilating surgery, but also raise important questions of balancing locoregional treatment de-escalation and protecting excellent long-term outcomes. Recent findings Recent studies have aimed at investigating the safety of de-escalating surgical approaches not only in the upfront breast surgery situation but also after neoadjuvant syste...

Postneoadjuvant treatment for triple-negative breast cancer
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 cl...

Circulating tumour DNA dynamics for assessment of molecular residual disease and for intercepting resistance in breast cancer
Purpose of review Longitudinal evaluation of circulating tumour DNA (ctDNA) represents a promising tool for monitoring tumour evolution. In patients with breast cancer, ctDNA dynamics for the assessment of molecular residual disease (MRD) and resistances may, respectively, help clinicians in treatment modulation of adjuvant treatments, and in anticipating resistance to ongoing treatments and switch treatments before clinical progression, to improve disease control. Anyway, the introduction of this dynamic biomarker into clinical practice requires the demonstration of analytical validity, clinical validity and clinical ...

Immunotherapy and breast cancer: an overview
Purpose of review Recently, immune checkpoint inhibitors (ICI) have demonstrated survival benefits in triple-negative breast cancer (TNBC) patients, treated in both the advanced and the early settings. Recent findings As monotherapy, ICI failed to demonstrate a superiority over chemotherapy in pretreated advanced TNBC. In the first-line setting, ICI in combination with chemotherapy have shown consistent gains in progression-free survival in programmed death-ligand 1-positive TNBC, but only pembrolizumab indisputably demonstrated a significant overall survival benefit. In early-stage TNBC patients treated with ne...

Biomarkers and immunotherapy: where are we?
Purpose of review Here, we reviewed the recent breakthroughs in the understanding of predictive biomarkers for immune checkpoint inhibitors (ICI) treatment. Recent findings ICI have revolutionized cancer therapy enabling novel therapeutic indications in multiple tumor types and increasing the probability of survival in patients with metastatic disease. However, in every considered tumor types only a minority of patients exhibits clear and lasting benefice from ICI treatment, and due to their unique mechanism of action treatment with ICI is also associated with acute clinical toxicities called immune related adve...

T-cell-engaging antibodies for the treatment of solid tumors: challenges and opportunities
Purpose of review T-cell-engaging antibodies or T-cell engagers (TCEs) can connect a patient's cytotoxic T cells with cancer cells, leading to potent redirected lysis. Until very recently, only one TCE was approved, the CD19/CD3-bispecific blinatumomab. Many new TCEs in late-stage clinical development target various hematopoietic lineage markers like CD20, BCMA, or CD123. Although very compelling single-agent activity of TCEs was observed with various blood-borne cancers, therapy of solid tumor indications has thus far been less successful. Recent findings The approval in 2022 of the gp100 peptide-major histoc...
