A Novel Target Delineation Scheme in High-grade Glioma Patients: a Randomized Single-blind Clinical Trial

The main question it aims to answer are: 1. whether the new target delineation scheme can improve Progression-free Survival 2. whether it can reduce the incidence of radiation complications in high-grade glioma patients. Participants in trial group will be performed radiotherapy of new target delineation method after the completion of the operation within 4-6 weeks., while participants in the control group be performed radiotherapy of EORTC(European organisation for research and treatment of cancer) target delineation method.Temozolomide 75 mg / ( m² · d ) will be given to both groups of patients during radiotherapy. After radiotherapy, its dose changes to 150 \~ 200 mg / ( m² · d ) for 5 days and stopped for 23 days as a cycle. There are 6 cycles in total.

Prospective Multicenter Clinical Study of Neoadjuvant Imatinib Mesylate for Gastrointestinal Stromal Tumors

The R0 resection rate of gastrointestinal stromal tumor (GIST) with high recurrence risk was relatively low, and the relapse-free survival rate was relatively low, which needed to be further improved. A few retrospective analyses and a small sample of prospective studies have found that neoadjuvant therapy with imatinib mesylate can improve R0 resection rates. Whether neoadjuvant therapy prolongs long-term survival remains unclear. The primary objective of this study was to evaluate 5-year progression-free survival (PFS) for GIST patients with high recurrence risk after neoadjuvant treatment with imatinib mesylate.
