Intraoperative Sonographically Guided Resection of Non-enhancing Gliomas
The purpose of the study is to determine whether intraoperative ultrasound guided resection of glioma without contrast enhancement in magnetic resonance imaging can achieve higher extent of resection than surgery without intraoperative sonography

Intraoperative Sonographically Versus Fluorescence-guided Resection of Contrast-enhancing Gliomas and Brain Metastases
Objective of the study is to determine whether intraoperative ultrasound guided resection of gliomas with contrast enhancement in magnetic resonance imaging and brain metastases can achieve as high rate of gross total resection as fluorescence-guided surgery with 5-aminolevulinic acid

Intra-pemetrexed Plus Third-generation Small Molecule TKI Drugs (e.g. 'Osimertinib') Versus Third-generation Small Molecule TKI Drugs Alone for Leptomeningeal Metastasis from Epidermal Growth Factor Receptor Mutation-Positive Non-Small-cell Lung Cancer
Intrathecal chemotherapy is one of the mainstay treatment options for leptomeningeal metastases. Pemetrexed is one of the first-line chemotherapeutic agents for non-squamous non-small cell lung cancer (NSCLC). Since 2017, intrathecal pemetrexed has shown good efficacy for patients with leptomeningeal metastases from NSCLC. It has been recommended as the preferred drug for intrathecal chemotherapy by the Chinese Society of Clinical Oncology (CSCO) guidelines. Tyrosine kinase inhibitors (TKIs) play a promising role in the treatment of non-small cell lung cancer patients with epidermal growth factor receptor (EGFR) mutations. Due to its small molecule properties, it can...

Intrathecal Application of PD1 Antibody in Metastatic Solid Tumors With Leptomeningeal Disease (IT-PD1/ NOA 26)
To determine the safety of intrathecal (IT) PD1 antibody for Intrathecal application of PD1 antibody in metastatic solid tumors with leptomeningeal disease of solid tumors.

Intrathecal Chemotherapy for Central Nervous System Metastasis in Retinoblastoma
Retinoblastoma is the most common intraocular malignancy in infancy and childhood. The overall survival rate of retinoblastoma was reported to exceed 95% when children were early diagnosed with localized intraocular phase. The advanced retinoblastoma cases with central nervous system metastasis (CNS)is associated with exceedingly poor prognosis. CNS metastasis is the main cause of death in retinoblastoma. Meningeal involvement combined with spinal cord membrane involvement might be due to the meninges invasion and/or the spreading of CSF. As the most sensitive drug to retinoblastoma tumor cells in vitro, melphalan is the most important drug in the local treatment of...

Intrathecal Chemotherapy Through Ommaya Reservoir Upon Her-2 Negative Breast Cancer With Leptomeningeal Metastasis
This is a prospective, multicenter, randomized controlled, open-label investigator-initiated clinical study to evaluate the clinical efficacy and quality of life of intrathecal chemotherapy through Ommaya reservoir in combination with systematic chemotherapy versus systemic chemotherapy alone in patients with Her-2 negative breast cancer with leptomeningeal metastasis.

Intrathecal Combination of PD-1/VEGF Bispecific Antibody and Pemetrexed for Leptomeningeal Metastasis.
Leptomeningeal metastasis, characterized by tumor cells infiltrating and proliferating in the subarachnoid space, represents a distinct pattern of central nervous system involvement and is a fatal complication of malignant tumors. This study is a prospective, single-arm phase I/II clinical trial aimed at evaluating the safety and efficacy of intrathecal PD-1/VEGF bispecific antibodies combined with pemetrexed in treating leptomeningeal metastases from solid tumors, with the goal of identifying more effective treatment options.

Intrathecal Combination of Programmed Death-1 (PD-1)/Cytotoxic T-Lymphocyte-Associated Protein 4 (CTLA-4) Bispecific Antibody and Pemetrexed for Leptomeningeal Metastasis
Leptomeningeal metastasis, characterized by tumor cells infiltrating and proliferating in the subarachnoid space, represents a distinct pattern of central nervous system involvement and is a fatal complication of malignant tumors. This study is a prospective, single-arm phase I/II clinical trial aimed at evaluating the safety and efficacy of intrathecal Programmed Death-1 (PD-1)/Cytotoxic T-Lymphocyte-Associated Protein 4 (CTLA-4) bispecific antibodies combined with pemetrexed in treating leptomeningeal metastases from solid tumors, with the goal of identifying more effective treatment options.

Intrathecal Double Checkpoint Inhibition
The objective of the present study is to determine the feasibility and to explore anti-tumor activity of intrathecal double immune checkpoint inhibition for patients with newly diagnosed leptomeningeal metastases from non-small cell lung cancer without driver mutation or melanoma.

Intrathecal Double Checkpoint Inhibition in Combination with Pemetrexed
The objective of the present study is to evaluate the tolerability, feasibility, safety and therapeutic response of intrathecal administration of double checkpoint inhibition(QL1706) in combination with pemetrexed in patients with leptomeningeal metastasis.
