Study of Craniospinal Irradiation With Linac Based Volumetric Modulated Arc Therapy (VMAT) for Patients With Leptomeningeal Metastasis
The purpose of this study is to confirm the safety and efficacy of linac based Volumetric Modulated Arc Therapy (VMAT) for craniospinal irradiation (CSI) in solid tumor cancer patients with leptomeningeal metastasis. The primary aim is to determine if linac based VMAT CSI for leptomeningeal metastasis improves central nervous system (CNS) progression free survival (PFS) compared to the historical standard control CNS PFS in patients treated with Involved Field Radiation Therapy (IFRT).

Study of How Safe and Effective Tarlatamab is in Brain Cancers
This is a phase 2 study to assess how useful study drug tarlatamab is for the treatment of patients with recurrent/refractory oligodendroglioma or astrocytoma with a mutation in the IDH gene.

Study of Metabolic, Transcriptomic and Proteomic Characteristics in Relapsed Glioblastoma
Glioblastomas are the most frequent and aggressive malignant tumors of the CNS in adults, with almost systematic relapse despite treatment with surgery followed by radio-chemotherapy (STUPP protocol). The aim of this study is to better characterize transcriptomic, proteomic and metabolic changes in relapsed glioblastoma compared to the initial tumor, in order to identify new prognostic markers and potential new therapeutic targets.

Study of MT027 in Patients with Brain, Meninges, and Spinal Cord Metastatic Solid Tumors
MT027 is an off-the-shelf, allogeneic chimeric antigen receptor T cell (UCAR-T) injection prepared from healthy donor T cells targeting B7-H3. It is a next-generation, ready-to-use CAR-T product that can be used immediately and promptly for patients to solve the problem of unmet medical needs for a large number of patients who have a demand for CAR-T therapy but cannot receive it due to the common reasons of long production cycle, insufficient production capacity, and incompatibility of patients' T cells with the production conditions. In addition, the expected medical cost of allogeneic CAR-T cells is significantly lower, which can greatly alleviate the economic burden...

Study of MT027 in Patients with Recurrent or Progressive High-grade Glioma
The clinical protocol plans to preset three dose groups, namely 1×10⁷ cells per dose, 3×10⁷ cells per dose, and 6×10⁷ cells per dose. The injection will be administered once every three weeks, adopting a "3 + 3" dose escalation design. The dosing interval is based on the pharmacokinetic (PK), safety and preliminary efficacy data of MT027 investigator-initiated trial (IIT) previously conducted at Dushu Lake Hospital of Soochow University. Accordingly, it is recommended to maintain the dosing interval of once every three weeks, with a window period of ±7 days. According to past experience, the dosing cycle should be at least 6 cycles, with each cycle lasting 21 days. If patients...

Study of PembrolizumAb combiNeD With Cisplatin or carbOplatin and Etoposide in Treatment naïve Advanced meRkel Cell cArcinoma (MCC)
This is an open label, multicenter, phase II study evaluating the activity and safety of pembrolizumab combined with cisplatin/carboplatin and etoposide as first line treatment in patients with advanced MCC.

Study on Gene Evolution in Glioma Under Stress Therapy
Little is known about the evolution of genetic and epigenetic changes that occur in the progression of glioma. We inferred the evolution trajectories of matched pairs of primary tumors and progression tumor in situ fluid (TISF) based on deep whole-genome-sequencing data (ctDNA). A monocentric, Gene grouping controlled trial design was used to select patients. and to compare gene evolution of different subtypes of glioma under therapy. To predict the molecular reaction of bevacizumab treatment, clarify the mechanism of drug resistance of bevacizumab treatment.

Sub-lobectomy for IDH Wild-type and TERT Promoter Mutant Glioblastoma
Glioblastoma is recognized as the most common and aggressive form of primary malignant brain tumor, with treatment options that are limited and prognosis that is extremely poor, showing median progression-free survival of 12 months and median overall survival of less than 18 months. Surgical resection plays a critical role in the treatment, with the extent of resection significantly impacting patient outcomes. Historical approaches to surgical resection have evolved, moving from radical strategies to more conservative ones that aim to preserve normal brain function while removing the tumor as completely as possible. Recent studies have suggested that increasing the extent of...

Surgical and Pharmacological Efficacy of Knosp Grade 0-2 Prolactinoma
The investigators carried out a multi-center comparative study, involving hospitals including the Second Affiliated Hospital of Zhejiang University School of Medicine, Peking Union Medical College Hospital, West China Hospital, Wenzhou First Hospital, and Li Huili Hospital. This study aimed to compare the efficacy of medication and surgery for specific subtypes of microadenomas and clearly defined macroadenomas (Knosp grades 0-2), in order to determine which is more effective and which has fewer benefits, thereby enhancing the evidence base.
