Concurrent Involved-field Radiotherapy and Intrathecal Chemotherapy for Leptomeningeal Metastases From Solid Tumors

Summary

It has been proved that concurrent radiotherapy (RT) and intrathecal methotrexate (MTX) for leptomeningeal metastases (LM) from solid tumors with adverse prognostic factors showed great effectiveness and safety. Cytarabine(Ara-C) is another agent which is commonly used for intrathecal chemotherapy. The purpose of the study is to observe the effectiveness and safety of concurrent RT and intrathecal chemotherapy for LM from solid tumors. In addition, the effectiveness of these two types of agents (MTX and Ara-C) in the concurrent chemo-radiotherapy will be compared in this study. This is a randomized controlled, parallel group, and phase II clinical trial. The object of this study is newly diagnosis patients with leptomeningeal metastases from solid tumors, who will accept the treatment of involved-field RT combined with concurrent intrathecal-MTX or intrathecal-Ara-C, respectively. Major endpoint is clinical response rate. Secondary endpoints are time to progression,severe adverse events and overall survival.
