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.

At present, it has become one of the most common malignant tumors and the main cause of cancer death worldwide. While early screening is recognized as an effective preventive and therapeutic measure for BC, the disease continues to exhibit a high rate of metastasis. Metastatic BC is still the main cause of poor prognosis and death of patients, necessitating urgent investigation and resolution. Among the various metastatic sites of BC, bone metastases warrant particular attention due to their prevalence. In numerous studies on BC bone metastasis mechanisms, cancer markers have been shown to significantly influence the pattern and extent of BC metastasis and dissemination. In the tumor microenvironment, Ras-proximate-1 (RAP1), a GTPase protein, is not only upregulated in various malignant tumors and bone-related diseases, including BC, but also regulates migration, invasion, distant metastasis, and other signaling pathways in numerous malignant tumor cells, including BC as well. Despite these findings, there remains a paucity of advanced research and discussion on the relationship between RAP1 and BC bone metastasis. Furthermore, no clinically approved RAP1-related inhibitors for BC bone metastasis are currently available. Nevertheless, RAP1 and its associated signaling molecules represent potential molecular targets for the prevention and treatment of BC bone metastasis, warranting further investigation. Therefore, this article provides a comprehensive review of RAP1's pathogenic role in BC bone metastasis, emphasizes RAP1 and its associated signaling pathways, and summarizes current research on natural compounds and extracts that modulate BC bone metastasis via RAP1 or RAP1-related signaling pathways.

We tried to find out the effectiveness and safety of 2-SSRS plus bevacizumab therapy for brain metastases that compress the brainstem, and prognostic factors that related to the tumor local control. A retrospective analysis was conducted on patients treated at five gamma knife treatment centers to assess changes in tumor size and peritumoral edema volume. Cox regression model was used to find out prognostic factors for tumor local control. Clinical symptom changes were evaluated using the Headache Scale (VAS), Dizziness Disorder Inventory (DHI), Vomiting Scale (VS), and Glasgow Coma Scale (GCS).

Despite significant advances in the treatment of primary lung cancer, the unique microenvironment of the brain renders current therapeutic strategies largely ineffective against brain metastasis. The lack of effective drugs for brain metastasis treatment is primarily due to the incomplete understanding of the mechanisms underlying its initiation and progression. Currently, our understanding of brain metastasis remains limited, primarily due to the absence of appropriate models that can realistically simulate the entire process of tumor cell detachment from the primary site, circulation through the bloodstream, and eventual colonization of the brain. Therefore, there is a pressing need to develop more suitable lung cancer brain metastasis models that can effectively replicate these critical stages of metastasis. Here, based on the traditional carotid artery injection model, we established a novel orthotopic mouse model by using a light-controlled hydrogel to repair the puncture site on the carotid artery, with sustained cerebral blood circulation and the capability of multiple delivery cancer cell to mimic lung cancer brain metastasis. The optimized orthotopic mouse model significantly reduced cerebral ischemia and improved cerebral oxygenation by 60% compared to the traditional orthotopic mouse model, enhancing post-operative survival rates. It also showed a reduction in pro-inflammatory cytokines and featured less inflammatory and more resting states of microglial and astrocyte cells. Furthermore, the optimized orthotopic mouse model markedly increased the success rate and absolute number of the metastatic clones in the brain. Additionally, the multiple delivery model based on the optimized orthotopic mouse model substantially augmented the tumor clone number and formation rates compared to single injection in the optimized orthotopic mouse model. This model overcomes previous limitations by maintaining cerebral circulation, providing a more accurate simulation of the continuous entry of tumor cells into cerebral circulation.

In our study we evaluated the association of concomitant use of antibiotics (ATBs), proton pump inhibitors (PPIs), corticosteroids, statins, metformin and insulin with patient outcomes and we validated the prognostic role of a concomitant drug score in mUC patients treated with enfortumab vedotin (EV) monotherapy. Data from 436 patients enrolled in the ARON-2<sup>EV</sup> retrospective study were analyzed according to the concomitant medications used at baseline. Finally, the patients were stratified into three risk groups according to the concomitant drug score based on ATBs, corticosteroids and PPIs. Statistical analysis involved Fisher exact test, Kaplan-Meier method, log-rank test, and univariate/multivariate Cox proportional hazard regression models. Inferior survival outcomes were observed in ATB users compared to non-users (OS: 7.3 months, 95%CI 5.0 - 12.3 vs 13.7 months, 95%CI 12.2 - 47.3, p = 0.001; PFS: 5.1 months 95%CI 3.3 - 17.7 vs 8.3 months, 95%CI 7.1 - 47.3, p = 0.001) and also in corticosteroid users compared to non-users (OS: 8.4 months, 95%CI 6.6 - 10.0 vs 14.2 months, 95%CI 12.7 - 47.3, p < 0.001; PFS: 6.0 months 95%CI 4.6 - 7.9 vs 8.9 months, 95%CI 7.2 - 47.3, p = 0.004). In the Cox multivariate analysis, the concomitant drug score was a significant factor predicting both OS (HR = 1.32 [95% CI 1.03 - 1.68], p = 0.026) and PFS (HR = 1.23 [95% CI 1.01 - 1.51], p = 0.044). Our findings suggest detrimental impact of concomitant use of ATBs and corticosteroids on survival outcomes and the prognostic utility of the concomitant drug score in previously treated mUC patients receiving EV.</p>","PeriodicalId":10267,"journal":{"name":"Clinical & Experimental Metastasis","volume":"42 2","pages":"18"},"PeriodicalIF":4.2,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11842414/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143457032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
