HER-2 overexpression

Neoadjuvant cisplatin-based combination chemotherapy or perioperative durvalumab with neoadjuvant gemcitabine-cisplatin has been the primary treatment for localized muscle-invasive bladder cancer (MIBC)...Twenty-five patients (cT2-4aN0-2M0) received at least four cycles of RC48 (2.0 mg/kg, Q2W or Q3W) with toripalimab, tislelizumab, or pembrolizumab, followed by radical cystectomy...Treatment-related adverse events were manageable. These findings suggest that RC48 combined with PD-1 inhibitors is a promising neoadjuvant strategy for localized MIBC and warrants further validation in biomarker-selected populations.

The treatment resulted in a complete response, with a tolerable side effect profile and ongoing treatment-free survival. Our case adds to the literature suggesting clinical benefit of the use of Trastuzumab-deruxtecan in HER2-positive tumors, and underscores the importance of molecular testing for patients with rare tumor subtypes.

In addition, the internalization mechanism of AfB constructs in SKOV3 cells was investigated due to the measurement of their fluorescence following trypsin treatment. In conclusion, our innovative synthetic approach with the integration of a versatile fluorescent platform offers new perspectives for monitoring molecular therapeutics inside cell and for tuning multivalent conjugates for cancer immunotherapy.

Temporal analysis showed conversion rates of 50.0% for synchronous metastases, 30.8% within 12 months, and 63.6% beyond 12 months. We identified a high prevalence of HER2-low and HER2-ultralow subtypes, suggesting potential eligibility for ADC therapies.

This study identifies a significant association between HER2 overexpression and lymph node metastasis in gastric cancer, suggesting HER2 expression is associated with more advanced lymph node involvement in this cohort; no significant association with overall survival was observed (log-rank p=0.58), though its impact on survival remains inconclusive.

In summary, this study highlights the critical role of CAND1 in regulating HER2 ubiquitination and suggests a potential therapeutic strategy for patients with HER2-positive breast cancer.

In the past few years, circulating tumour DNA has emerged as a minimally invasive biomarker, with increasing data supporting its prognostic value and utility for monitoring clinical responses. In this Review, we address these developments and discuss biomarkers that could have clinical utility in patients with aUC.

CELF1 promotes aerobic glycolysis and aggressive behavior in ER-positive breast cancer, at least partly by regulating GLUT1. These findings reveal RBP-driven metabolic reprogramming in luminal A disease and nominate the CELF1-GLUT1 axis as a potential therapeutic vulnerability.

Colchicine reduces viability and modifies GAG concentrations in 3D cultures of MCF-7 cells. The use of MRI provides a reproducible, non-destructive tool for monitoring extracellular matrix changes, offering a novel methodological approach for studying drug effects in physiologically relevant cancer models.

This study elucidates the complex interplay of direct and bystander effects in targeted radionuclide therapy, demonstrating that the therapeutic efficacy and cellular response depend on the specific radionuclide and its energy profile. The findings emphasize the need for further exploration of RIBBEs to optimize radionuclide-based cancer therapies to enhance their clinical efficacy.

She received carboplatin/paclitaxel plus avelumab, followed by pegylated liposomal doxorubicin and weekly paclitaxel. This case illustrates that T-DXd can induce deep and durable remission in HER2-positive, dMMR metastatic serous endometrial cancer after multiple lines of therapy. It adds real-world evidence supporting further investigation of HER2-directed antibody-drug conjugates in gynaecologic malignancies, and underscores the need for confirmatory trials and refined biomarker-driven patient selection.
