This prospective multicentre study aimed to evaluate the efficacy of ECT in the treatment of patients with skin metastases from breast cancer and confirm whether \"luminal A-like\" tumors are more responsive to treatment. One-hundred and ninety-five patients were included in the analysis. 55% achieved complete response, 27% partial response (objective response OR 82%); 12% stable disease and 5% experienced progressive disease. The analysis by tumor phenotype showed a significant better response rate in Luminal A-like (p = 0.0060) and Luminal B-like (p = 0.0271) groups compared to Triple-Negative. Patients were divided into 4 groups based on the number and size of cutaneous metastases. Higher response rate was observed in patients with small (≤ 3 cm), single or multiple, metastases (OR rate 95% and 90%, respectively); larger tumors (> 3 cm) showed an OR rate of 85%. Tumor response was not affected by the presence of distant metastases, whereas patients with large cutaneous lesions and distant metastases showed a OR rate of 58%. One-year local progression-free survival (LPFS) was 86% (C.I. 82-89%). In the multivariate analysis, patient age and response to ECT were significantly associated with longer LPFS. This study confirms the efficacy of ECT in small-volume cutaneous metastases from breast cancer regardless the presence of systemic disease and suggests higher efficacy in patients with luminal A- and luminal B-like tumors. ECT can be utilized not only as a palliative measure but also as an alternative treatment for patients not eligible for standard treatments, or in combination with them.

Up to four persistent liver metastases per patient were treated with CT-guided brachytherapy (CT-BRT). Treatment response was evaluated using the Response Evaluation Criteria in Solid Tumors (RECIST 1.1).

Stereotactic body radiation therapy (SBRT) has emerged as a promising local treatment, offering durable tumor control with minimal toxicity. However, the optimal dosimetric strategies to maximize outcomes remain an area of active investigation. This retrospective study evaluated 76 patients with 101 liver metastases treated with SBRT between November 2012 and June 2024. Dosimetric parameters were analyzed, including prescribed dose (PD) and dose metrics for planning target volume (PTV) and gross tumor volume (GTV), with doses converted to equivalent doses in 2 Gy fractions (EQD2, α/β = 10). Tumor control probability (TCP) models and survival outcomes were assessed, with a focus on the prognostic impact of dosimetric and clinical factors. Median overall survival (OS) was 33 months, with 1-year and 3-year OS rates of 74.1% and 39.4%, respectively. Freedom from local progression (FFLP) was 82.5% at 12 months. PD emerged as the strongest independent predictor of local control, with an optimal threshold of 77.44 Gy EQD2 significantly improving 1-year FFLP rates (96.8% vs. 67.2%; p = 0.007). Advanced motion management techniques, including internal breath-hold (iBH) with image-guided radiotherapy (IGRT), demonstrated superior local control outcomes. Predictive modeling confirmed PD as the most robust dosimetric metric, correlating with a high TCP and outperforming other dose metrics. Toxicity was minimal, with only 3.9% experiencing grade ≥ 3 adverse events. SBRT represents a highly effective and safe approach for liver metastases, with PD and advanced imaging emerging as pivotal determinants of tumor control. These findings underscore the importance of precise dosimetric planning and motion management in optimizing SBRT outcomes.

The lack of effective long-term treatment options for brain metastasis significantly increases morbidity and mortality among these patients. Therefore, understanding the underlying mechanisms that drive brain metastasis is critically important for developing new strategies to treat it effectively. Genetically engineered mouse models (GEMMs) of HER2⁺ breast cancer have been instrumental in understanding the development and progression of HER2⁺ breast cancer. However, the GEMM models for HER2⁺ breast cancer do not develop brain metastasis and are not suitable for the study of brain metastasis. We therefore developed a fully immunocompetent mouse model of experimental brain metastasis in HER2⁺ breast cancer by injecting a murine HER2/neu-expressing mammary-tumor-cell line into the arterial circulation of syngeneic FVB/N mice followed by isolation of brain-metastatic derivatives through in-vivo selection. By this in-vivo serial passaging process, we selected highly brain-metastatic (BrM) derivatives known as neu-BrM. Notably, after intracardiac injection, neu-BrM cells generated brain metastasis in 100% of the mice, allowing us to study the later stages of metastatic progression, including cancer-cell extravasation and outgrowth in the brain. Analogous to human brain metastasis, we observed reactive gliosis and significant immune infiltration in the brain tissue of mice injected with neu-BrM cells. We further confirmed that brain-metastatic lesions in the neu-BrM model express HER2. Consistently, we found that the brain-metastatic burden in these mice can be significantly reduced but not eliminated with tucatinib, an FDA-approved, blood-brain-barrier-penetrant HER2 inhibitor.

The functional role of TEAD4 in the progression of gallbladder cancer was investigated through CCK-8, EdU assays, Transwell, wound-healing assays, western blotting, immunohistochemistry, and hematoxylin and eosin (H&E) staining in cellular and animal models. The potential regulatory mechanism was explored by chromatin immunoprecipitation and dual-luciferase reporter assays.
