Filter by:This clinical trial aims to investigate the value of fibroblast activation protein PET/CT(PET/MR) in the diagnosis, staging, and evaluation of treatment outcomes in malignant tumors. The main question it aims to answer is: Fibroblast Activation Protein PET/CT(PET/MR) whether or in which cases this assay is superior to conventional FDG examination in the diagnosis, staging, and assessment of therapeutic efficacy of malignant tumors, thinking about the reasons behind this. Investigators will screen suitable participants among patients undergoing routine FDG examination. - Participants will sign an informed consent form - Undergo 68Ga-FAPI PET/CT (PET/MR) before surgery or biopsy - Surgical resection or puncture biopsy to obtain pathologic results. Diagnosis of patients with malignant tumors at first diagnosis; clinical staging of tumors; and clinical outcomes of patients with confirmed diagnoses will be assessed after postoperative investigator follow-up. The researchers will compare the FDG exams the participants have had to determine the effectiveness of the fibroblast activating protein test.
This study is an open-labeled phase II diagnostic clinical trial to explore the safety and clinical value of BBPA-PET/CT in suspected malignant tumor patients. The investigation regarding the clinical value of BBPA concerning the metabolic characteristics of BBPA in suspected malignant tumors. Quantitative features will be extracted to analysis the PET images. For patient who took surgery after multiple examination, histopathology, molecular pathology and LAT-1 immunohistochemistry will also be obtained.
The purpose of this study is to evaluate the efficacy and safety of mRNA vaccine for the EBV-positive Advanced Malignant Tumors.
This study is to assess the safety and tolerability, obtain Maximum Tolerated Dose (MTD) and/or the recommended phase 2 dose (RP2D) of LM-101 as a single agent or in combination in patients with advanced malignant tumors
This trial is an open and multicenter phase Ib/II clinical study, which aims to evaluate the safety, tolerability, PK characteristics, immunogenicity, and effectiveness.
Polyplastic glioblastoma and metastatic brain cancer are the most common malignant brain tumors in adults. The primary diagnostic test for tumors in the brain shows magnetic resonance imaging or similar imaging findings (especially single metastatic brain cancer) that make it difficult to distinguish between these two diseases. In addition, due to the specificity of the tissue called the brain, biopsy is not easy and sometimes biopsy is difficult, so non-invasive discrimination is often important, and it is important how much prediction is made before the biopsy. To solve this problem, various advanced magnetic resonance imaging techniques have been studied, but they are all tests that need to be additionally conducted on ordinary magnetic resonance images, and there are many subjective factors, so complex data and statistical processing methods, and many cannot be easily tested. In addition, in all of these tests, accuracy is still reported at around 60%. Therefore, if contrast-enhanced FLAIR images can be obtained along with contrast-enhanced T1 images performed during conventional magnetic resonance imaging tests to help differentiate between two diseases, it will greatly help diagnose and treat brain tumor patients and facilitate clinical application.
This is a study on the clinical application of chimeric antigen receptor modified γδ T cells (CAR - γδ T cells) in relapsed and refractory CD7 Positive T cell-derived malignant tumors.The main purpose of this study was to evaluate the efficacy of car - γ δ T cell infusion in patients with relapsed and refractory CD7 Positive T cell-derived malignancies.
To use 18F-DCFPyL imaging agent and PET/CT to detect none prostate cancer solid malignancies and schwannoma tumors.
Malignant tumor incidence showed an upgrade trend in recent years. Standard therapy for malignant tumor includes surgery followed by radiation and chemotherapy. Despite optimal treatment the prognosis remains poor. There is an urgent need for more effective therapies. The Warburg effect has been widely observed in human cancers. The main energy supply of tumor cells are aerobic glycolysis. Therefore, they are highly dependent on glucose metabolism. Recently, some scholars have suggested that 'Restricted calorie Ketogenic Diet (RKD)' might be able to inhibit glycolysis and thus anti-tumor by restricting carbohydrate intake. This will 'starve' cancer cells, which will lead to cell death. There are many animal and in vitro studies shown that RKD can reduce the tumor size and thus tumor cell growth of malignant tumors. However, a consistent positive result can not be found within a small sample of clinical trials. In this study, 40 patients with malignant tumors will be treated with or without RKD. The safety and efficacy of RKD and the patients' tolerance will be observed in order to understand whether this therapy can be a potential new treatment This clinical study is comparatively large internationally. It is the first domestically. This study is essential to extend the survival of patients with malignant tumors, and to study clinical nutrition support and its metabolic pathways for malignant tumors.
