This study aims to perform ⁶⁸Ga-DOTA-mPNE PET/CT imaging in patients with clinically suspected or confirmed malignant tumors, in order to evaluate tracer uptake in lesions and analyze CD73 expression levels. In a subgroup of up to 10 participants, dynamic PET/CT imaging will be conducted for up to 90 minutes post-injection to assess the tracer's biodistribution and pharmacokinetic properties.Correlation analyses with relevant clinical indicators (such as pathology, immunohistochemistry, and molecular markers) will be carried out to further assess the diagnostic performance and clinical value of ⁶⁸Ga-DOTA-mPNE PET/CT in guiding tumor diagnosis and treatment. This study is expected...
Pituitary adenomas are one of the most common primary central nervous system tumors and have an estimated prevalence of 17%. Management of pituitary adenomas involves a multidisciplinary approach that can incorporate surgical, medical, and/or radiation therapies. Over the last two decades, the endoscopic endonasal approach (EEA) has been extensively developed and refined for the resection of pituitary adenomas (PAs). In recent years, extracapsular resection (ER), which emphasized the importance of the pseudocapsule between the adenoma and surrounding normal gland tissue as a surgical plane, was adopted for more radical resection of the tumor. Therefore, dedicated high-resolution...
This will be a prospective, randomized, standard of care (SoC) controlled, parallel, open-label, multicenter pivotal study to investigate the efficacy and safety of Bevacizumab (BEV) in combination with or without microbubble (MB)-mediated FUS in patients with recurrent GBM. BEV represents the physician's best choice for the standard of care in rGBM after previous treatment with surgery (if appropriate), standard radiotherapy with temozolomide chemotherapy, and with adjuvant temozolomide.
Tumor genotyping has become an essential biomarker for the care of advanced lung cancer and melanoma, and is currently used to identify patients for treatment with targeted kinase inhibitors like erlotinib and vemurafenib. However, tumor genotyping can be slow and cumbersome, and is limited by availability of tumor biopsy tissue for testing. The aim of this study is to prospectively evaluate a blood-based genotyping tool that can quantify the presence of oncogenic mutations (EGFR, KRAS, BRAF) in patients with lung cancer and melanoma. This assay is being studied both as a diagnostic tool for classifying patient genotype, and a serial measurement tool for quantification of response...
Whole brain radiotherapy (WBRT) has long been a practical and effective therapeutic modality for various settings of management in radiation oncology. For example, the indications for WBRT should include brain metastasis or metastases, the setting of prophylactic cranial irradiation (PCI) used mainly for patients with limited-stage small cell lung cancer, and even some patients with extensive-stage small cell lung cancer. The rationales for WBRT are essentially based on that it can target both microscopic and gross intracranial disease. In addition to providing rapid alleviation of neurologic symptoms and enhanced intracranial disease control, WBRT might also prolong the time to...
The goal of this prospective, single-arm exploratory clinical study is to explore the safty and efficacy of whole-brain radiotherapy combined with Thiotepa sheath injection combined With Systemic Therapy for the Primary Disease in the Treatment of Meningeal Metastases in Solid Tumors How works well was the combined therapy？ How safe was combined therapy？ Participants will receive whole brain radiotherapy combined with intrathecal injection of Thiotepa twice a week for a total of 4 weeks. Evaluate the efficacy and safety every 2 cycles. Researchers will evaluate whether this combination treatment is safe and whether it is more effective than previous studies.
The goal of this clinical trial is to learn how roginolisib works in comparison to standard treatment in adult patients with uveal/ocular melanoma. The main questions it aims to answer are: Does roginolisib extend overall survival compared to standard treatment? How does dosing of roginolisib impact quality of life compared to standard treatment?
Currently, there is no widely used adjuvant treatment available to improve survival after surgical excision of a primary melanoma. In a previous study, loco-regional and systemic immune stimulations, as well as favourable clinical outcomes in terms of sentinel lymph node (SLN) tumor status and recurrence-free survival (RFS) in patients with clinical stage I-II melanoma who received a low dose of toll-like receptor 9 (TLR-9) CPG7909 (CpG-B ODN) intradermally at the excision site of the primary tumor prior to SLN biopsy (SNB) were described. In this phase II trial the investigators had investigated the clinical activity of a next-generation CpG-ODN, IMO-2125, and it's ability to...
The purpose of this study is to measure the clinical benefits of the combination of RP2 and nivolumab as compared with the combination of nivolumab and ipilimumab in patients with metastatic uveal melanoma who have not been treated with immune checkpoint inhibitor therapy.
Because of their prolonged survival, patients with 1p/19q-codeleted low-grade oligodendrogliomas treated with RT + PCV are at risk of neurocognitive deterioration. We make the hypothesis that withholding radiotherapy until tumor progression could reduce the risk of neurocognitive deterioration without impairing overall survival.
