Study Arms (1)
experimental arm
EXPERIMENTALGroup A: multiple brain metastases: no less than 3 lesions in the brain Group B: Large Brain Metastases: the volume of lesion is no smaller than 6cc or the maximum diameter of the lesion is no shorter than 3cm Group C:Meningeal Metastases. Intervention:tomotherapy
Interventions
Tomotherapy: The regular fraction modes were as follows: a. lesions≥3 cm:52Gy/4Gy/13f or 52.5Gy/3.5Gy/15f; b. lesions\<2cm:36Gy/12Gy/3f or 24Gy/24Gy/1f; for lesions located in function areas, it would be adjusted to 40Gy/8Gy/5f; c. lesions 2-3cm: 40-48Gy/8-10Gy/6-4f; d. lesions located in brainstem:50-60Gy/2.5-3Gy/20f; 3. multiple lesions with large lesion: whole brain radiation (WBRT) with 40Gy/2Gy/20f and concurrent boost of 60Gy/3Gy/20f of the lesions. TMZ is used if necessary: concomitant TMZ: 75mg/m2 adjuvant TMZ: 150mg/ m2\*5d, q28d, up to 6cycles.
Eligibility Criteria
You may qualify if:
- Histologic or cytologic diagnosis of primary tumor and conformed brain metastases by enhanced MRI or CT; the lesion number is no less than 3; or the tumor volume is no smaller than 6cc; or tumor diameter is no shorter than 3cm; or uncontrolled brain tumor after whole brain radiotherapy(WBRT); or the tumor is adjacent to essential structures of the brain, such as brain stem, optic chiasma, optic tract, etc; KPS ≥60,or KPS ≥40 and the limitation of motion is simply caused by brain tumor that is adjacent to the motor function areas; Age: 18-75 years old;
- Adequate end-organ function:
- WBC≥4.0x109/L Neu ≥ 1.5x109/L Hemoglobin ≥ 110 g/L Platelets ≥100 x109/L Total bilirubin ≤ 1.5x ULN AST and ALT ≤ 1.5x ULN BUN and Cr: within the normal range.
You may not qualify if:
- Other clinically significant diseases (e.g.myocardial infarction within the past 6 months, severe arrhythmia).
- Unable or unwilling to comply with the study protocol.
- The expected survival time is less than 3 months.
- Patients who are anticipated in other clinical trials of brain metastases.
- Patients who has been treated with SRT in other hospitals
- Pregnant patients or female patients whose HCG is positive
- Unsuitable to participate in study, that in the opinion of the treating physician.
