1970年美国诊断脑瘤63,000例,其中恶性肿瘤占25,000例,良性肿瘤为24,000例和转移性肿瘤14,000例。由于癌肿病人生存时间延长,脑转移癌患者数量显著增多。一般肿瘤中心的报导:在尸解中发现25～35%癌转移到脑部。近年,每5个神经肿瘤的住院病人就有一个脑转移性肿瘤。近年来脑瘤的诊断有了新的进展,装备了电子计算机的X线断层脑扫描是广泛应用的新方法,可以高度灵敏性和选择性取得脑组织图像。Fischgold认为现在还难想象这个方法在多大程度上影响神经外科的发展。现在,大概还不能代替或大幅度减
In 1970, the United States diagnosed 63,000 brain tumors, of which 25,000 were malignant, 24,000 were benign and 14,000 were metastatic. Due to prolonged survival of cancer patients, the number of patients with brain metastases increased significantly. General Cancer Center reports: In the autopsy found that 25 to 35% of cancer metastasis to the brain. In recent years, there have been one brain metastatic tumor in hospitalized patients for every 5 neuro-tumor. In recent years, there has been new progress in the diagnosis of brain tumors. Brain tomography equipped with a computerized tomography is a widely used new method that can acquire brain tissue images with high sensitivity and selectivity. Fischgold says it’s hard to imagine how much this method will affect neurosurgery. Now, probably not yet replaced or significantly reduced
