Summary

Cerebral metastases are common intracranial tumor, its incidence increased year by year, in recent years, although the whole brain radiation therapy, surgical resection, stereotactic radiosurgery treatment, targeted drugs, and other comprehensive treatment in patients with symptoms of mitigation and the extension of survival has played a positive role, but due to individual differences, treatment in patients with poor compliance were a lot of factors, Further treatment of brain metastases after conventional treatment requires the assistance and cooperation of clinical multi-disciplines. To evaluate the efficacy and safety of percutaneous Ommaya capsule injection of autologous bi-dimensional specific T cells in the treatment of glioma and combined with pemetrexed in the treatment of brain/meningeal metastasis. Using translational research techniques and means, to find molecular indicators related to clinical prognosis and outcome, establish the clinical use standard of this holistic treatment technology, and popularize it in multi-centers.

Conditions

• Glioma
• Brain Metastases

Interventions

Type	Name	Description
BIOLOGICAL	Autologous progenitor expansion -T	After the completion of RAK cell culture, RAK cells were slowly injected into the tumor cavity through Ommaya capsule for no less than 10 minutes, each time about 1.0-4.0 108/4 mL, once a week,3 times as a course of treatment. Il-2 (500,000 units/capsule) was injected into the tumor cavity through Ommaya reservoir every other day after the injection of RAK cells In other words, the day of RAK cell injection was the first day, and the third and fifth days were respectively injected. Then, about LML of sac fluid was pumped back before each injection to observe the growth of RAK cells in the tumor cavity. Il-2 was dissolved with LML normal saline, and the fluid storage sac was pressed 3-5 times after injection to make the sac fluid and IL-2 fully mixed.
DRUG	pemetrexed	For patients with brain metastasis from solid tumor that met the inclusion conditions, the Ommaya capsule was placed 2 days later, and the maximum tolerated dose of pemetrexed intrathecal chemotherapy was injected intravaginally at 10mg according to the general situation of the patients and the results of the previous study.
