Guided Meditation During Radiation Therapy for Brain Tumors
The goal of this interventional treatment study is to assess the anxiolytic effect of providing guided meditation during radiation treatment (RT) in patients with brain tumors. The main question it aims to answer is: • What is the change in acute anxiety in participants receiving the mindfulness intervention during radiation therapy compared to standard of care control conditions? Participants will be asked to participate in a 5-minute, audio-recorded mindfulness practice that will be played during the administration of each RT session. Researchers will compare this intervention to standard of care (no intervention) during RT.

Head-to-head Study of 68Ga-MGS5 Versus 68Ga-DOTATATE PET/CT in Patients With Medullary Thyroid Carcinoma
Cholecystokinin-2 (CCK2) receptor is overexpressed in more than 90% of MTC cases, and preclinical studies have shown that 68Ga-MGS5 (targeting CCK2) has good stability in vivo and is promising for diagnosis and staging of MTC. This prospective study will compare the diagnostic effects of 68Ga-MGS5 and 68Ga-DOTATATE on MTC primary foci, lymph node metastasis, and distant metastasis, and explore the effect of 68Ga-MGS5 PET/CT on the clinical staging (TNM staging) of MTC.

HER2-specific Chimeric Antigen Receptor (CAR) T Cells for Children With Ependymoma
This is a Phase I study to evaluate the safety profile of a type of immune therapy called HER2 CAR T cells (short for HER2 chimeric antigen receptor T cells). In addition to looking for side effects, we will study how well this treatment works against a brain tumor called ependymoma that has come back after treatment (recurrent) or has not responded well to treatment (progressive) in children. The HER2 CAR T cells used in this trial are made from the patient's own blood. A new gene, called the HER2 CAR, will be inserted into patient's T cells to allow them recognize a protein on the tumor called HER2. These HER2-specific CAR T cells may be able to target and kill ependymoma...

Hereditary Pheochromocytoma Assessment of Tumour Immunologies
In this study, the investigators are examining the role of the immune system in pheochromocytoma and paraganglioma. The investigators aim to examine the differences in the immune system between people who have these tumors with and without a hereditary predisposition. The investigators also want to see how the immune system changes during the development of the tumor in people with a hereditary predisposition. Finally, the investigators will compare the data with a control group of people without these tumors. Ultimately, the investigators hope that the results will contribute to the discovery of new immune system-targeted medications for pheochromocytoma and paraganglioma.

Hetrombopag in Promoting Platelet Engraftment After Auto-HSCT in Children with Neuroblastoma
The goal of this clinical trial is to learn if hetrombopag promotes platelet engraftment in neuroblastoma children undergoing autologous hematopoietic stem cell transplantation. The main question it aims to answer is: · Does drug hetrombopag promote platelet engraftment? Participants will take hetrombopag every day for 6 weeks or until platelet > 100*10^9/L.

High-Dose Gemcitabine, Busulfan, and Thiotepa Followed by ASCT in Primary Central Nervous System Lymphoma
The goal of this single-arm, prospective study is to learn if high dose gemcitabine, busulfan and thiotepa with autologous stem cell transplantation to treat primary or relapse central nervous system lymphomas. It will learn about the safety and efficacy of combination therapy. The main question it aims to answer is: Efficacy and safety of the combination of high dose gemcitabine, busulfan and thiotepa as a bridging therapy to ASCT in patients with CNSL. Participants will: Take gemcitabine (2.5 g/m²) was administered intravenously (IV) on Days -9 and -3, Busulfan (3.2 mg/kg) was given IV over 3 hours on Days -9 to -7, and thiotepa (5 mg/kg) was administered IV on Days -5,...

High-dose Topotecan for Retinoblastoma With Recurrent or Refractory Vitreous Seed
Retinoblastoma is the most common intraocular malignancy in infancy and childhood,with an estimated 8000 new cases globally each year.The major cause of failure in the management of retinoblastoma remains the persistence or recurrence of resistant vitreous seeding.Currently,with the emergence of new administration routes, intravitreal chemotherapy has been used for vitreous seeds and the rate of eye preservation has been effectively improved. However, the use of high doses of chemotherapeutic agents may lead to visual impairments due to long term retinal toxicity and some tumors recur or become resistant to chemotherapeutic agents after treatment. In such cases, ocular resection...
