Plain-language summary
Intrathecal chemotherapy is one of the most important treatment modalities for leptomeningeal metastasis of solid tumors. In the previous retrospective study, it has been proved that concurrent radiotherapy and intrathecal methotrexate for leptomeningeal metastasis from solid tumors with adverse prognostic factors showed great effectiveness and safety. The preliminary results of investigators' current prospective clinical study (Involved-field Radiotherapy Combined With Concurrent Intrathecal-methotrexate Versus Intrathecal-Ara-C for Leptomeningeal Metastases From Solid Tumor: A Randomized Phase II Clinical Trial. ClinicalTrials.gov identification number: NCT03082144) also showed that the regimen of concurrent intrathecal chemotherapy and radiotherapy may serve as an optimal therapeutic option for treatment of leptomeningeal metastases from solid tumors. Pemetrexed is a newer multitargeted antifolate which has shown activity in various tumors. In investigators' current study (Intrathecal Pemetrexed for Recurrent Leptomeningeal Metastasis From Non-small Cell Lung Cancer: A Prospective Pilot Clinical Trial. ClinicalTrials.gov identification number: NCT03101579), the regimen of intrathecal pemetrexed with folic acid and vitamin B12 supplementation may provide higher effectiveness and safety for recurrent leptomeningeal metastasis from non-small cell lung cancer. Therefore, the purpose of the study is to evaluate the tolerability, safety and effectiveness of intrathecal pemetrexed combined with involved-field radiotherapy as the first line treatment in patients with leptomeningeal metastases from malignant solid tumors.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
