Efficacy and safety of antibody-drug conjugates in pretreated HER2-low metastatic breast cancer: A systematic review and network meta-analysis.

Introduction: Antibody-drug conjugates (ADCs) trastuzumab-deruxtecan (T-DXd) and sacituzumab-govitecan (SG) provided significant progression-free survival (PFS) and overall survival (OS) improvements over chemotherapy (CT) in pretreated hormone receptor-positive (HR+) and triple-negative (TN)/HER2-low metastatic breast cancer (MBC). However, no direct comparison between the two exists, nor with the more recent datopotamab-deruxtecan (Dato-DXd).

Methods: We conducted a network meta-analysis (NMA) to compare efficacy and safety of T-DXd and SG in CT-pretreated HR+ and TN/HER2-low MBC and assess their benefit over standard CT, exploring also a comparison with Dato-DXd.

Protocol for generating a co-culture of macrophages with breast cancer tumoroids.

Cancer progression and treatment outcomes are heavily influenced by the tumor microenvironment (TME), especially through immune cell interactions. Here, we present a protocol for generating co-cultures of tumoroids with macrophages, either semi-liquid or Matrigel-embedded. We describe steps for macrophage preparation, co-culture establishment, and medium adjustments to support cell viability and function.

Background: The combination of immunotherapy and chemotherapy has demonstrated an enhancement in progression-free survival (PFS) for individuals with advanced and metastatic triple-negative breast cancer (TNBC) when compared to the use of chemotherapy alone. Nevertheless, the extent to which different subgroups of metastatic TNBC patients experience this benefit remains uncertain.

Objectives: Our objective was to conduct subgroup analyses to more precisely identify the factors influencing these outcomes.

Development of a hydrogel-based three-dimensional (3D) glioblastoma cell lines culture as a model system for CD73 inhibitor response study.

Background: Despite the development of various therapeutic approaches over the past decades, the treatment of glioblastoma multiforme (GBM) remains a major challenge. The extracellular adenosine-generating enzyme, CD73, is involved in the pathogenesis and progression of GBM, and targeting CD73 may represent a novel approach to treat this cancer. In this study, three-dimensional culture systems based on three hydrogel compositions were characterized and an optimal type was selected to simulate the GBM microenvironment.

E3 ubiquitin ligase ITCH-mediated proteasomal degradation of WBP2 sensitizes breast cancer cells to chemotherapy through restraining AMOTL2/c-JUN axis.

Our study had demonstrated that WW domain-binding protein 2 (WBP2) conferred chemoresistance in breast cancer (BC). However, the underlying mechanism remains unclear. Herein, a decreased expression of itchy E3 ubiquitin protein ligase (ITCH) was observed in drug-resistant BC tissues which negatively regulated the expression of WBP2.

Redox/NIR dual-responsive glutathione extended polyurethane urea electrospun membranes for synergistic Chemo-Photothermal therapy.

Despite advancements in cancer treatments, therapies frequently exhibit high cytotoxicity, and surgery remains the predominant method for treating most solid tumors, often with limited success in preventing post-surgical recurrence. Implantable biomaterials, designed to release drugs at a localised site in response to specific stimuli, represent a promising approach for enhancing tumour therapy. In this study, a redox-responsive glutathione extended polyurethane urea (PolyCEGS) was used to produce paclitaxel (PTX) and gold nanorods (AuNRs) loaded electrospun membranes for combined redox/near-infrared (NIR) light-responsive release chemotherapy and hyperthermic effect.

Modular self-emulsifying drug delivery platform to enhance cellular uptake activity in triple-negative breast cancer.

Triple-negative breast cancer (TNBC) presents with resistance phenotypes to certain therapies, such as cisplatin, often requiring higher dosing, with associated acquired tumor resistance, renal toxicity, and variable patient responses. A self-emulsifying drug delivery (SEDD) formulation approach was proposed to overcome the limitations of cisplatin in TNBC, focusing on improving intracellular cisplatin and control siRNA uptake as a proof-of-principle of dual drug delivery. Four SEDD formulations were prepared and optimized for cisplatin (o/w) emulsion and FITC-siRNA (w/o) emulsion using pseudo-ternary phase diagrams to facilitate the formation of water-in-oil-water (w/o/w) emulsions.

METTL3-mediated CEP170 m6A modifications in spindle orientation and esophageal cancer cell proliferation.

Esophageal cancer is a major malignancy with a high incidence and poor prognosis. To elucidate the mechanisms underlying its progression, particularly with respect to cell division and spindle orientation, we investigated the role of m6A modifications and the centrosomal protein CEP170. Using m6A-seq and RNA-seq of esophageal cancer tissues and adjacent normal tissues, we identified significant alterations in m6A modifications and gene expression, highlighting the upregulation and m6A enrichment of CEP170 in tumor tissues.

Breast cancer is the most commonly diagnosed cancer worldwide, with early detection and advanced treatments contributing to declining mortality rates. However, managing comorbid conditions, particularly mental illness, presents significant challenges for cancer treatment. This study systematically reviews and meta-analyses the impact of having a pre-existing mental illness on breast cancer treatment utilisation, focusing on specific treatments and comparing different mental illnesses.

Beyond Hormone Receptors: liquid biopsy tools to unveil new clinical meanings and empower therapeutic decision-making in Luminal-like metastatic breast cancer.

Immunohistochemical (IHC) tissue profiling is a standard practice in the management of metastatic breast cancer (mBC), that enables the identification of distinct biological phenotypes based on hormone receptors' expression. Luminal-like tumors primarily benefit from a first line treatment strategy combining endocrine therapy and cyclin-dependent kinase 4/6 inhibitors. However, IHC analyses necessitate invasive procedures and may encounter technical and interpretational challenges.
