This is a multicenter, two-arm, open-label, randomized controlled phase III clinical trial to evaluate the efficacy and safety of tunlametinib capsule in comparison with the combination chemotherapy of investigator's choice in advanced melanoma patients with NRAS mutation who have received immunotherapy before. Subjects were stratified according to the baseline lactate dehydrogenase level and chemotherapy.
This study aims to compare the surgical outcomes of laparoscopic spleen-preserving distal pancreatectomy using the Kimura technique versus the Warshaw technique. The primary focus is on the rates of unplanned splenectomy, occurrence of severe complications, as well as intraoperative and perioperative outcomes of both techniques.
ReciDOPA is a phase II, single-stage randomized, multicenter, prospective trial assessing the efficacy of an irradiation protocol based on Intensity-modulated radiation therapy with simultaneous-integrated boost guided by FDOPA-PET in patient with recurrent glioblastoma.
In newly diagnosed glioblastoma patients aged 70 years or older who are suitable for concurrent temozolomide, the optimal dose of radiation therapy is controversial . The purpose of this study is to compare conventional radiotherapy of 60 Gy (6 weeks) versus hypofractionated radiotherapy of 40 Gy (3 weeks) in terms of overall survival as the primary endpoint along with progression-free survival, toxicity, quality of life, and prognostic biomarkers.
It is a single-center, prospective, observational,non-randomized study of newly diagnosed glioblastoma patients conducted in a tertiary hospital. The investigators examine the psychological stress, immune biomarker changes, quality of life, and disease progression of patients with glioblastoma at five-time points. The study had two cohorts, a high-stress cohort and a low-stress cohort, which are grouped after initial recruitment. Both groups undergo total resection of tumors and received 3 months of standardized treatment with radiotherapy and chemotherapy. Neither participants nor doctors but the researcher can choose which group...
It is a single-center, prospective, observational, non-randomized study of newly diagnosed diffuse astrocytoma patients conducted in a tertiary hospital. The investigators conduct an eight-year follow-up, including patients' psychological stress, immune biomarker changes, quality of life, and disease progression of patients towards secondary glioma after the first definite diagnosis. In the first year after diagnosis, patients are followed up four times at 1 month, 3 months, 6 months, and 12 months. After that, patients are followed up semiannually. The study had two cohorts, a high-stress cohort and a low-stress cohort, which are...
It is a single-center, prospective, observational, non-randomized study of newly diagnosed oligodendroglioma patients conducted in a tertiary hospital. The investigators conduct an eight-year follow-up, including patients' psychological stress, immune biomarker changes, quality of life, and disease progression of patients towards secondary glioma after the first definite diagnosis. In the first year after diagnosis, patients are followed up four times at 1 month, 3 months, 6 months, and 12 months. After that, patients are followed up semiannually. The study had two cohorts, a high-stress cohort and a low-stress cohort, which are...
Major advances in cancer genetics over the past decade have revealed that the genes encoding IDHs are frequently mutated in a variety of human malignancies, including gliomas.Pentavalent 99mTc dimercaptosuccinic acid (99mTc (V) DMSA), is a nonspecific tumor targeting SPECT radiotracer, that has been used for imaging of various tumors including lung and breast carcinoma. However, to date, scarce reports discussed the utility of DMSA-V in patients with glioma.SPECT has the advantages of being widely available and not expensive. Multiple SPECT tracers have been explored. Of them Thallium-201 and 99 mTc-MIBI are, possibly, the most ...
Background: Cushing s disease is caused by a pituitary gland tumor. Patients with Cushing s disease suffer obesity, diabetes, osteoporosis, weakness, and hypertension. The cure is surgery to remove the pituitary tumor. Currently, MRI is the best way to find these tumors. But not all tumors can be seen with an MRI. Researchers hope giving the hormone CRH before a PET scan can help make these tumors more visible. Objective: To test whether giving CRH before a PET scan will help find pituitary gland tumors that might be causing Cushing s disease. Eligibility: People ages 8 and older with Cushing s disease...
For investigators' current experimental clinical trial, patients are given 4 injections of ipilimumab, given 3 weeks apart x 4 injections with or without cytokine-induced killer therapy. Investigators propose to test this dual therapy in patients with melanoma who have known stage I, metastatic melanoma. Investigators hypothesize that this form of combinatorial immunotherapy will result in tumor stabilization or shrinkage, significant prolongation of progression-free, disease-free or overall survival compared to the use of ipilimumab alone
