详细描述

This Phase II study is to determine the efficacy and safety of MR-Linac Guided Radiotherapy in patients with inoperable mediastinal tumors.

Patients will receive radiotherapy on the MR-Linac treatment machine. The primary end point is 2-year local-recurrence free survival. The secondary end points are objective response rate, 2-y PFS, 2-y OS, safety of treatment, dose coverage of targets and dose to normal organs.
