This study is a single-center, prospective, open-label, single-arm clinical study of an innovative integrated treatment regimen for recurrent glioblastoma multiforme. The main outcome measurement of the study is to evaluate the safety of the integrated treatment regimen for glioblastoma multiforme. Secondary outcome measurement are OS, PFS, ORR, and quality of life. Safety is evaluated by monitoring adverse events, physical examination results, vital signs, ECG, hematology, and clinical biochemistry. Imaging was performed at the end of every 3 sessions to assess treatment outcome and disease progression. The whole treatment and efficacy will be observed for two years.

Arms

Experimental: integrated treatment regimen(TRPP)

Interventions

Drug: - TMZ

After enrollment, temozolomide 50mg/m2 was given orally for QD until progression, and radiotherapy and PF 0.2g/ time for TID were started one week later until progression. Pembrolizumab 200mg once every 3 weeks until progression; The radiotherapy regimen depends on the patient's recurrence and initial treatment.
