Recurrent High Grade Glioma Treated by LITT

Summary

This clinical trial aims to investigate the efficiency and safety of laser interstitial thermal therapy (LITT) in recurrent high-grade glioma (rHGG) patients. The main questions it aims to answer are: * The LITT would increase the progression-free survival and overall survival of rHGG patients compared to other treatments. * The LITT is safe and applicable to rHGG patients Participants will be randomized to the intervention group (LITT) or control group at a ratio of 2:1. The intervention group patients will receive LITT. The control group will be treated with any other treatment. The primary outcome of this trial is progression-free survival. The estimated sample size is 135, 90 in the LITT group and 45 in the control group.
