脑转移癌化疗效果不满意,全脑放疗平均存活期仅为3～6个月,手术切除加全脑放疗可延长生存期,但当病灶多发或位于手术不易达到的部位时则限制了手术的开展.本文报道立体定向放射外科治疗33例脑转移性病变的经验.男17例,女16例.平均年龄55岁.原发恶性肿瘤均获病理确诊,并已得到恰当治疗.其中腺癌23例,恶性黑色素瘤4例,肾细胞癌3例,鳞癌2例、睾丸癌1例.共有脑转移灶52个,分别位于顶、额、脑干、枕、小脑、脑深部灰质和颅骨底、多发性脑性转移13例(39%),经CT或MRI和脑立体定向活检确诊.经CT扫描立体定位,应用4-MeV线性加速器放射外
Chemotherapy of brain metastases is not satisfied, the average survival of whole brain radiation is only 3 to 6 months, surgical resection plus whole brain radiation can prolong survival, but when the lesions occur frequently or in difficult to reach parts of surgery is limited surgery This article reports the experience of stereotactic radiosurgery in the treatment of 33 cases of brain metastatic lesions, 17 males and 16 females with an average age of 55. The primary malignant tumors were pathologically confirmed and have been properly treated .Adenocarcinoma 23 For example, 4 cases of malignant melanoma, 3 cases of renal cell carcinoma, 2 cases of squamous cell carcinoma and 1 cases of testicular cancer.A total of 52 brain metastases were located in the top, forehead, brainstem, occipital, cerebellum, deep brain gray matter and skull base , Multiple brain metastases in 13 cases (39%), confirmed by CT or MRI and stereotactic stereotactic stereotactic CT scan, the application of 4-MeV linear accelerator outside the emission
