The primary objective of this study is to demonstrate the non-inferiority of cCeLL compared to frozen section analysis. The investigational device is intended for use with indocyanine green (ICG) for fluorescence imaging as an aid in the visualization of vessels (micro- and macro-vasculature) blood flow in the cerebrovascular before, during or after cranial diagnostic and therapeutic procedures, such as tumor biopsy and resection, which is then read and analyzed by trained-professional for intraoperative diagnosis. The comparison will be held by the device with the conventional intraoperative histological frozen section analysis of identical brain tissue samples in the...
The goal of this observational study is to gain new insights into the changes in proteins, genes and other molecular biological substances in the aqueous humour, vitreous humour, blood serum and, in rare cases, retina/choroid samples in patients with ocular lymphoma disease. The hope is that this will expand the understanding of the mechanisms of the disease and thus contribute to improved and simplified diagnosis and treatment strategies in the future. The aim is the inclusion of at least 220 patients during the study period. The main questions it aims to answer are: - to evaluate the diagnostic quality of extended molecular diagnostics (based on standard work-up) of...
1. To retrospectively explore the feasibility of multi-dimensional heterogeneity imaging features of MRI in predicting the status of key gene mutations in high-grade gliomas; 2. To prospectively explore the correlation between multi-dimensional heterogeneous MRI image features and prognosis of high-grade glioma patients.
- To perform metabolic phenotyping of treatment naïve and recurrent GBM by multitracer [18F]Fluciclovine and 18F-FDG PET. - To compare uptake measures of 18F-Fluciclovine and 18F-FDG and MRI quantification of glutamate and lactate levels to tumor tissue laboratory assays (RNA seq and proteomics) of glutamine/glutamate, glucose, and lactate metabolism. - To perform metabolic phenotyping of treatment naïve and recurrent GBM by advanced MRI methods at 7 Tesla
Participation in medical trials usually favors a particular demographic group. But there is limited research available to explain what trial attributes affect the completion of these specific demographic groups. This trial will admit a wide range of data on the clinical trial experience of glioma patients to determine which factors prevail in limiting a patient's ability to join or finish a trial. It will also try to analyze data from the perspective of different demographic groups to check for recurring trends which might yield insights for the sake of future glioma patients.
This is a single-arm, multicenter clinical trial conducted in patients ≥ 12 months of age with high-risk neuroblastoma in first complete response. 62 patients will be enrolled to receive naxitamab + GM-CSF in combination with isotretinoin. In line with post-consolidation maintenance treatment of high-risk neuroblastoma, this trial will include patients with high-risk neuroblastoma in first complete response. Patients must have completed a multimodal frontline regimen (induction and consolidation) and have achieved complete response (positive bone marrow minimal residual disease as assessed by RTqPCR is allowed) following the multi agent induction and consolidation therapy.
Preclinical data have demonstrated the combination of azeliragon, a RAGE inhibitor, with radiation therapy (RT) can effectively reduce immune-suppressive myeloid cells and restore T-cell activation to improve tumor control in murine glioma models. Ongoing clinical studies of azeliragon with RT alone and RT plus temozolomide (TMZ) to treat patients with newly diagnosed glioblastoma (GBM) have demonstrated safety and tolerability. The purpose of this window-of-opportunity study is to validate that the combination of azeliragon with RT and TMZ would modulate immune-suppressive myeloid and T cells in the tumor microenvironment in patients with GBM.
To Determine the feasibility, compliance and adherence to PreFED intervention in resectable melanoma patients initiating neoadjuvant Ipi/Nivo.
This phase II trial tests how well tebentafusp works to shrink tumors prior to primary treatment with surgery or radiation in patients with uveal (eye) melanoma that has spread to nearby tissue or lymph nodes (locally advanced) or that cannot be removed by surgery (unresectable). Tebentafusp is a drug that binds to melanoma tumor cells as well as immune cells called T-cells. This binding causes an immune response against the melanoma cells, which leads to tumor cell death. Tebentafusp has been approved for the treatment of locally advanced and unresectable uveal melanoma. Giving tebentafusp before primary treatment with surgery or radiation may help shrink the tumor, prevent the...
Ameloblastoma is the most common benign odontogenic tumor, characterized by high local invasiveness and a high recurrence rate. Currently, surgical treatment is the standard treatment modality. The main surgical approaches include radical resection represented by local extended resection (with a safety margin of more than 2 cm) and conservative procedures represented by curettage and fenestration. Although radical resection can effectively treat the disease, it often leads to severe jaw bone defects and even disrupts the continuity of the jaw bone. However, the conservative procedures have a recurrence rate of approximately 40%. This study aims to reduce the recurrence rate of...
