Study on The Sensitizing Effect of Sonodynamic Therapy on The Treatment of Brainstem Glioma With Radiotherapy and Chemotherapy and Survival Analysis

SDT: Hematoporphyrin 5 mg/kg.Sonodynamic therapy is administered 40 hours later, twice a day with an interval of 10-12 hours, for 5 consecutive days. One cycle lasts 28 days, and a total of 4-6 cycles are conducted Radiotherapy: The dose is 50-54 Gy, 1.8-2 Gy per day, 5 times a week, for a total of 25 sessions Chemotherapy: When temozolomide is administered concurrently with radiotherapy, the dose is 75 mg/m² per day, taken daily until the end of radiotherapy. For adjuvant chemotherapy with temozolomide, the dose is 150 mg/m² per day from day1to day 5, followed by a 23-day rest period. Each cycle lasts 28 days. If well-tolerated, the dose should be adjusted to 200 mg/m² per day for the 2nd - 6th cycles Targeted Therapy: Bevacizumab 7.5-10 mg/kg, once every 3 weeks, for a total of 4-6 courses
