Neuroendocrine neoplasms (NENs) comprise a heterogeneous family of neoplasms arising from the neuroendocrine cells localized in endocrine glands or from the diffuse neuroendocrine cells such as in the digestive or lung tract. Treatment for gastroenteropancreatic neuroendocrine tumors (GEP-NEC) is primarily based on chemotherapy regimens, primarily platinum, which achieve limited benefit and a median overall survival of approximately 12 months. Currently, new treatments that activate the immune system to stimulate antitumor responses and prolong survival in patients with NECs are being investigated. Given the high levels of DLL3 expression on the cell surface of...
The REMIT (RE-irradiation of diffuse MIdline glioma paTients) study evaluates safety and the palliative efficacy of re-irradiation of patients with diffuse midline glioma (DMG). The study will introduce a standard re-irradiation treatment schedule for DMG patients who have progressed following primary treatment.
There are several predictors of clinical outcome in patients undergoing brain tumor surgery. Among those, nutritional parameters and calculated nutritional index are known to have ability to predict mortality and clinical outcomes in some patients with brain tumor. However, there are lack of consistent results on predictability of nutritional index and clinical outcome in patients undergoing brain tumor surgery.
The purpose of this study is to evaluate the repeatability of magnetic resonance imaging (MRI) in patients with isocitrate dehydrogenase 1 (IDH1) mutant (mIDH1) low-grade diffuse glioma [World Health Organization (WHO) grade 2] who are receiving off-label ivosidenib.
The goal of this clinical trial is to learn about the safety and feasibility of administering repeated doses of neural stem cell (NSC)-conditionally replicative adenovirus (CRAd)-survivin (S)-protomer (p)k7, in persons with newly diagnosed high grade glioma. The main questions it aims to answer are: - whether multiple doses of NSC-CRAd-S-pk7 are safe and feasible - how multiple doses of NSC-CRAd-S-pk7 influence tumor response, overall survival, time to tumor progression, and quality of life. Participants will: - undergo a biopsy to confirm high grade glioma, then receive the first dose of NSC-CRAd-S-pk7 into the brain - about 2 weeks later,...
According to the latest national cancer statistics released by the National Cancer Center in February 2022, intracranial tumors account for about 60%-70% of the more than 3.5 million cancer patients, and the morbidity and mortality remain high. Intracranial malignant tumors have become a problem that needs to be solved urgently because of their early recurrence, rapid progression, and short survival, and intracranial malignant tumors include high-grade gliomas, metastases, lymphomas, etc. Glioblastoma (GB) is the most common primary malignancy in the adult central nervous system, accounting for about 57% of all gliomas and 48% of all primary weighted nervous system malignancies....
When possible, surgery to completely remove small intestinal neuroendocrine tumors (siNETs) is always recommended. However, in cases where the tumor has spread and cannot be cured completely, it is unclear whether a surgical removal of the primary tumor only is reasonable. In this situation, current guidelines from the European Neuroendocrine Tumor Society (ENETS) recommend surgery only for patients who have symptoms like intestinal blockage or bleeding, or are at risk of such complications. For patients without symptoms, it is still unclear whether removing the main tumor improves overall outcomes and prevents future problems. Studies evaluating this type of surgery on survival...
The aim of this proposal is to identify immune biomarkers, genetic risk, and the clinical consequences of low count monoclonal B-cell lymphocytosis (LC MBL), a common premalignant condition affecting up to 17% of European adults age>40. LC MBL is a precursor to chronic lymphocytic leukemia (CLL), characterized by a circulating population of clonal B-cells. It is relatively understudied, despite emerging evidence of clinical consequences such as increased risk for life-threatening infections and lymphoid malignancies. Studies reported that male sex, age, family history of CLL, and CLL-susceptibility genetic loci were associated with LC MBL risk. These findings were reported...
This multi-center, prospective, observational study aim to construct a comprehensive model, integrating common clinical pathological parameters, radiographic features and multi-omics data, for assessing the risk and prognosis of brain metastasis in NSCLC. This model is intended to address the following clinical needs: (1) Identify patients at high risk of brain metastasis; (2) Optimize the combined strategies of local and systemic treatments; (3) Predict the survival outcomes of patients with brain metastases from NSCLC and provide evidence-based support for individualized treatment decisions.
Recent studies show an increase in neuroendocrine neoplasms, especially for the digestive tract. Previous studies suggest various risk factors that were observed for various tumor sites, e.g. a family history of cancer, tobacco and alcohol consumption as well as metabolic disorders including diabetes and obesity. A risk factor that has been little studied to date is depressive disorders, which could increase the risk of neuroendocrine neoplasms either independently or through associated risk behaviors and/or antidepressant medication. The aim of this study is to identify risk factors for neuroendocrine neoplasms based on a case-control study in order to better understand the...
