癌症患者存活期延长使脑转移瘤变得多见.化疗效果差而放疗几成为唯一手段.尽管是治标性,放疗常能改善症状及延长存活期,且一般都能耐受.现介绍196例的放疗经验.196例中男131例女65例,平均年龄56岁.原发癌已知有支气管肺癌114例、乳腺癌46例、黑色素瘤7例,消化道、子宫及肾癌18例,11例原发癌未明.44例伴其它部位转移,主要为骨转移.51例因脑转移才发现癌症.急性起病74例,37例曾拟为脑血管意外;渐进起病122例,常表现颅内压增高.放疗前神经状况分期(Order等的分类,1968):Ⅰ期12例(轻微或无神经征),Ⅱ期90例(神经征不严重),Ⅲ期83例(严重神经征),Ⅳ期16例(昏迷、神经征严重).脑转移经锝99闪烁照相诊断者186例,CT诊断70例,部份病人两法兼用.单个转移103例,多发转移76例、17例记录不明.转移部位:顶叶58例,
Prolonged survival of cancer patients so that brain metastases become more common.Cefficient chemotherapy and radiotherapy several times become the only means.Although is a palliative, radiotherapy often can improve symptoms and prolong survival, and are generally able to tolerate.Now 196 cases are introduced Of the 196 cases of male and 131 cases of female 65 cases, mean age 56. Primary cancer is known to have 114 cases of bronchial lung cancer, 46 cases of breast cancer, melanoma in 7 cases, digestive tract, uterus and kidney cancer in 18 cases, Eleven cases of primary carcinoma were unknown, 44 cases were associated with metastasis of other sites, mainly bone metastases, 51 cases of cancer were found due to brain metastases, 74 cases of acute onset and 37 cases of cerebrovascular accidents were proposed, progressive onset of 122 cases, often The performance of intracranial pressure increased before radiotherapy of neurological staging (Order classification, 1968): Ⅰ in 12 cases (mild or no neurological symptoms), Ⅱ phase 90 cases (neurological symptoms are not serious), Ⅲ period 83 cases (severe nerve 186 cases of brain metastasis were diagnosed by technetium 99 scintigraphy, 70 cases were diagnosed by CT, and 103 cases were single metastasis and 76 cases were multiple metastasis Cases recorded unknown.
