Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this prospective, single-arm exploratory clinical study is to explore the safty and efficacy of whole-brain radiotherapy combined with Thiotepa sheath injection combined With Systemic Therapy for the Primary Disease in the Treatment of Meningeal Metastases in Solid Tumors

How works well was the combined therapy? How safe was combined therapy? Participants will receive whole brain radiotherapy combined with intrathecal injection of Thiotepa twice a week for a total of 4 weeks. Evaluate the efficacy and safety every 2 cycles.

Researchers will evaluate whether this combination treatment is safe and whether it is more effective than previous studies.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants will receive a comprehensive treatment plan consisting mainly of whole brain 30Gy/10F radiotherapy combined with intrathecal injection of Thiotepa. The injection was administered by qualified individuals (certified personnel in the radiotherapy department of our hospital) twice a week for a total of 4 weeks. Thiotepa was injected 10mg each time, mixed with cerebrospinal fluid, and then injected slowly for 5-10 minutes. Evaluate the efficacy and safety every 2 cycles.
