Socioeconomic impact of artificial intelligence-driven point-of-care testing devices for liquid biopsy in the OncoCheck system.

Cancer disparities in low- and middle-income countries (LMICs) persist because of socioeconomic inequalities and limited access to screening infrastructure, which requires equitable diagnostic solutions. As researchers, we need to develop interventions which mirror successful strategies from high-income countries (HICs) to address mortality inequalities. Routine cancer diagnosis functions as a fundamental element of effective management yet remains unavailable to numerous populations in LMICs.

Molecular Mechanisms and Clinical Divergences in HPV-Positive Cervical vs. Oropharyngeal Cancers: A Critical Narrative Review.

Human papillomavirus (HPV) plays a pivotal role in the development of both cervical squamous cell carcinoma (CSCC) and oropharyngeal squamous cell carcinoma (OPSCC). However, these two cancers exhibit markedly different clinical behaviors. While HPV-positive OPSCC is distinguished by its heightened radiosensitivity, enabling effective treatment de-escalation and reduced toxicity, HPV-positive CSCC shows no such advantage, requiring aggressive therapeutic approaches similar to HPV-negative cases.

Trastuzumab plus lapatinib or chemotherapy in patients with HER2-overexpressed advanced breast cancer: a randomized, phase II trial (GIM12-TYPHER).

Background: Trastuzumab combined with chemotherapy is a standard treatment for human epidermal growth factor receptor 2 (HER2)-positive advanced breast cancer in later lines. Lapatinib and trastuzumab have also demonstrated efficacy. This study assessed the efficacy, toxicity, and quality of life (QoL) of trastuzumab plus lapatinib (with endocrine therapy for hormone receptor-positive cases) versus trastuzumab with physician-selected chemotherapy in patients previously treated with at least 2 anti-HER2 regimens.

Towards liquid biopsy on chip for Triple Negative Breast Cancer: preliminary results on monitoring circulating miRNA-21 using portable diagnostics.

Liquid biopsy has emerged as a promising non-invasive, cost-effective and real-time approach for cancer diagnosis and monitoring, allowing for the detection of biomarkers in bodily fluids. Among these, microRNAs (miRNAs) are a valuable choice due to their stability and ability to reflect the tumor's heterogeneity. Concerning triple negative breast cancer (TNBC), an aggressive subtype, several studies have demonstrated consistent upregulation of miRNA-21.

Atezolizumab plus paclitaxel and bevacizumab as first-line treatment of advanced triple-negative breast cancer: the ATRACTIB phase 2 trial.

Triple-negative breast cancer (TNBC) is a highly aggressive subtype of breast cancer with poor prognosis. The current first-line treatment for advanced TNBC (aTNBC) is determined by the expression of programmed cell death-ligand 1 (PD-L1). In the ATRACTIB trial-a multicenter, single-arm, phase 2 study-we evaluated the combination of atezolizumab, paclitaxel and bevacizumab as first-line treatment for patients with aTNBC, independently of PD-L1 status.

Vepdegestrant, a PROTAC Estrogen Receptor Degrader, in Advanced Breast Cancer.

Background: Vepdegestrant is an oral proteolysis-targeting chimera (PROTAC) estrogen receptor (ER) degrader that directly harnesses the ubiquitin-proteasome system.

Methods: In this phase 3, open-label, randomized trial, we enrolled patients with ER-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer who had received one previous line of cyclin-dependent kinase 4 and 6 inhibitor therapy plus one line of endocrine therapy (and up to one additional line of endocrine therapy). Patients were randomly assigned in a 1:1 ratio to receive vepdegestrant at a dose of 200 mg orally once every day of each 28-day cycle or fulvestrant at a dose of 500 mg, administered intramuscularly, on day 1 and day 15 of cycle 1 and on day 1 of subsequent cycles, with randomization stratified according to -mutation status and presence or absence of visceral disease.

However, optimal therapy after tumor progression to ET plus CDK4/6i remains unclear.

Objective: To evaluate progression-free survival (PFS) and overall survival (OS) in the clinical practice setting in patients with hormone receptor-positive, ERBB2-negative metastatic breast cancer following progression with ET plus CDK4/6i.

Paper-based electrochemical device for the determination of H₂S in murine lysates for liquid biopsy application.

Background: Hydrogen Sulfide (H₂S) is a biologically active endogenous gas, produced in mammalian tissues, which plays a critical role in several pathophysiological processes, including oncogenesis. This gas-transmitter can exert diametrically opposite effects on neoplastic cell proliferation, depending on the duration and concentration of H₂S exposure. Due to this dual role, antineoplastic drugs, aimed at modulating H₂S levels, are attracting considerable interest in both research and clinical settings.

Prognostic implications of risk definitions from the monarchE and NATALEE trials.

Background: The monarchE and NATALEE trials employed different high-risk inclusion criteria. The main objective is to assess prognostic differences based on their inclusion criteria.

Methods: Patients with hormone receptor-positive/HER2-negative early breast cancer enrolled in the phase III Mammella InterGruppo (MIG) 1, Gruppo Italiano Mammella (GIM) 2, and GIM3 trials were categorized as high-risk cohort (HRC) and low-risk cohort (LRC) according to the inclusion criteria of monarchE and NATALEE trials.

Real life outcome analysis of breast cancer brain metastases treated with Trastuzumab Deruxtecan.

Tumor dissemination to the central nervous system (CNS) is almost a rule in the treatment journey of advanced HER2+ breast cancer (BC). Recent results demonstrated high intracranial efficacy with Trastuzumab Deruxtecan (T-DXd). However, a real-world evidence is lacking in literature.

CAR-T cell therapy for breast cancer: Current status and future perspective.

Within the expanding therapeutic landscape for breast cancer (BC), metastatic breast cancer (MBC) remains virtually incurable and tend to develop resistance to conventional treatments ultimately leading to metastatic progression and death. Cellular immunotherapy (CI), particularly chimeric antigen receptor-engineered T (CAR-T) cells, has emerged as a promising approach for addressing this challenge. In the wake of their striking efficacy against hematological cancers, CAR-T cells have also been used where the clinical need is greatest - in patients with aggressive BCs.

Oleanolic Acid Modulates DNA Damage Response to Camptothecin Increasing Cancer Cell Death.

Targeting DNA damage response (DDR) pathways represents one of the principal approaches in cancer therapy. However, defects in DDR mechanisms, exhibited by various tumors, can also promote tumor progression and resistance to therapy, negatively impacting patient survival. Therefore, identifying new molecules from natural extracts could provide a powerful source of novel compounds for cancer treatment strategies.

Clinico-pathological predictors of radiologic complete response to first-line anti-HER2 therapy in metastatic breast cancer.

This study aimed to identify the clinico-pathological variables predictive of radiologic complete response (rCR) to first-line anti-HER2 therapy in patients with HER2-positive metastatic breast cancer. Patients were selected from the database of the GIM14 study and classified according to the best radiologic response obtained to first-line anti-HER2 therapy and upon time-to-treatment-discontinuation (TTD). A total of 545 patients were included in the analysis.

Warming-up the immune cell engagers (ICEs) era in breast cancer: state of the art and future directions.

The advent of immune checkpoint inhibitors (ICIs) has deeply reshaped the therapeutic algorithm of triple-negative breast cancer (TNBC). However, there is considerable scope for better engagement of the immune system in other BC subtypes. ICIs have paved the way for investigations into emerging immunotherapeutic strategies, such as immune cell engagers (ICEs) that work by promoting efficient tumor cell killing through the redirection of immune system against cancer cells.

Datopotamab Deruxtecan Versus Chemotherapy in Previously Treated Inoperable/Metastatic Hormone Receptor-Positive Human Epidermal Growth Factor Receptor 2-Negative Breast Cancer: Primary Results From TROPION-Breast01.

Purpose: The global, phase 3, open-label, randomized TROPION-Breast01 study assessed the trophoblast cell surface antigen 2-directed antibody-drug conjugate datopotamab deruxtecan (Dato-DXd) versus investigator's choice of chemotherapy (ICC) in hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR+/HER2-) breast cancer.

Methods: Adult patients with inoperable/metastatic HR+/HER2‒ breast cancer, who had disease progression on endocrine therapy, for whom endocrine therapy was unsuitable, and had received one to two previous lines of chemotherapy in the inoperable/metastatic setting, were randomly assigned 1:1 to Dato-DXd (6 mg/kg once every 3 weeks) or ICC (eribulin/vinorelbine/capecitabine/gemcitabine). Dual primary end points were progression-free survival (PFS) by blinded independent central review (BICR) and overall survival (OS).

Long-term behavioral symptom clusters among survivors of early-stage breast cancer: Development and validation of a predictive model.

Background: Fatigue, cognitive impairment, anxiety, depression, and sleep disturbance are cancer-related behavioral symptoms that may persist years after early-stage breast cancer, affecting quality of life. We aimed to generate a predictive model of long-term cancer-related behavioral symptoms clusters among breast cancer survivors 4 years after diagnosis.

Methods: Patients with early-stage breast cancer were included from the CANcer TOxicity trial (ClinicalTrials.

Parp-inhibitors in the therapeutic landscape of breast cancer patients with BRCA1 and BRCA2 pathogenic germline variants: An Italian consensus paper and critical review.

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 medications and those with proven efficacy. This study utilized the Delphi method to present the first Italian consensus regarding genetic testing, the use of PARP inhibitors in both early and metastatic settings, and strategies for managing the potential toxicity of these novel drugs.

VERITAC-2: a Phase III study of vepdegestrant, a PROTAC ER degrader, versus fulvestrant in ER+/HER2- advanced breast cancer.

Vepdegestrant (ARV-471) is an oral PROTAC ER degrader that binds an E3 ubiquitin ligase and ER to directly trigger ubiquitination of ER and its subsequent proteasomal degradation. In a first-in-human Phase I/II study, vepdegestrant monotherapy was well tolerated with clinical activity in pretreated patients with ER+/HER2- advanced breast cancer. The global, randomized Phase III VERITAC-2 study compares efficacy and safety of vepdegestrant versus fulvestrant in adults with ER+/HER2- advanced breast cancer after treatment with a CDK4/6 inhibitor plus endocrine therapy.
