By linear electron accelerator KD II of Siemens M evatron and RSA X-knife of the fourth generation produced by Radionics company, 44 patient with intracranial diseases were intervened through 1999,6-2000,4. The results are as following.1 Materials and Methods1.1 Mateials In the group,25 male,19 female aging from 8~74 years, meanly 43 years.Total 50 lesions were radiated.Of all the patients, 12 patients with metastatic tumors of brain (7 with solitary tumors,5 with multiple tumors);3 w… 相似文献

Objective to investigate therapeutic methods and effect of X-knife for on intracranial diseases. Method Recent effect of 44pqtients with cranial diseases by X-knife was observed. Radiological follow-up was performed on 40 cases with mean 5.65 months of followup time. Result 92.5% of tumors were controlled locally, stability and recovery rate was 90.0%. The local control of metastatic tumors of brain was higher, but most patients with metastatic tumors died of primary lesion. New metastatic lesions appeared in patients without panencephalic radiotherapy in 1~5months. Tumors of pineal region were sensitive to X-knife. Conclusion X-knife has a definite effect on intracranial diseases. For patients with tumors of pineal region complicated by serious hydrocephalus, shunting should be conducted before X-knife treatment. For patients with mild or morderate hydrocephalus, X-knife chould be utilized only under correct interventions such as dehydration. The local control rate of intracranial metastatic tumors was high, but survival time postoperation depended on panencephalic radiotherapy or control of primafry lision. For tumors with diameter> 3cm, pituitary tumors, brains stem tumors and tumors in cerebellopontine angle region repeated X-knife were suggested, which could improve cure rate and decrease complications. 相似文献
