简要总结
This phase I trial finds out the possible benefits and/or side effects of radiosurgery before surgery (preoperative) in treating patients with high grade glioma. Radiosurgery uses special equipment to position the patient and precisely give a single large dose of radiation to the tumor. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Giving pre-operative radiosurgery may improve the odds of brain tumor control and reduce treatment-related side effects.
详细描述
PRIMARY OBJECTIVE: I. To evaluate the feasibility, safety and maximum tolerated dose (MTD) of preoperative radiosurgery in the treatment of patients with biopsy-proven high-grade glioma prior to conventional therapy. SECONDARY OBJECTIVES: I. Acute clinical toxicity profile using Common Terminology Criteria for Adverse Events (CTCAE) version 5 (defined as within 4 weeks of completion of postoperative radiotherapy. II. Radiographic tumor control at 12 months following surgery (per Response Assessment in Neuro-Oncology \[RANO\] criteria). III. Rate of pseudoprogression at first post radiation scan (RANO criteria). IV. Overall survival at 12 months following surgery. CORRELATIVE RESEARCH OBJECTIVE: I. Evaluation of the tumor repair pathways triggered by radiation, tumor vascular changes, tumor microenvironment immune profiling, cell cultures, and the creation of orthotopic xenograft models for future study. OUTLINE: This is a dose-escalation study. Patients undergo magnetic resonance imaging (MRI)-guided stereotactic biopsy. Within 14 days of registration, patients undergo either standard of care surgery or radiosurgery in 1 fraction. Within 14 days, patients who underwent radiosurgery then undergo surgery. Within 4-6 weeks, all patients then receive standard of care radiation therapy over 30 fraction and temozolomide daily with or without tumor treating fields (TTF) at the discretion of the treating neuro-oncologist. Additionally, patients undergo MRI and blood sample collection and optional biopsy throughout the study. After completion of study treatment, patients are followed up every 2-3 months for 12 months and then every 3 months for up to 3 years after registration.

结局指标
主要结局
Proportion of patients experiencing any acute grade 3 or greater unplanned adverse event
时间窗: Up to 4 weeks postoperative radiotherapy
Assessed per Common Terminology Criteria for Adverse Events (CTCAE) version (v)5.0. The toxicity rate will be estimated using a binomial estimator and a one-sided 95% confidence interval (CI) of the rate will be computed with normal approximation.
Acute clinical toxicity
时间窗: Up to 4 weeks postoperative radiotherapy
Assessed per CTCAE v5.0. The maximum grade for each type of acute adverse events will be recorded for each patient. Data will be summarized as frequencies and relative frequencies by treatment arm. Additionally, the relationship of the adverse event(s) to the study treatment will be taken into consideration. Rates will be compared between arms using chi-squared tests.
Maximum tolerated dose (MTD) of preoperative radiosurgery
时间窗: Up to 4 weeks postoperative radiotherapy
After the trial is completed, the MTD will be based on isotonic regression. The dose for which the isotonic estimate of the toxicity rate is closest to the target toxicity rate will be selected as the MTD. If there are ties, the higher dose level will be selected when the isotonic estimate is lower than the target toxicity rate; and the lower dose level will be selected when the isotonic estimate is greater than or equal to the target toxicity rate.
次要结局
- Radiographic tumor control(At 12 months post-surgery)
- Rate of pseudoprogression(At first post radiation scan)
- Overall survival(At 12 months post-surgery)
