日本每年脑肿瘤患者约12000人,发病率为10/10万。脑实质肿瘤多为恶性浸润性增殖,手术时肉眼全切除也容易复发;实质外肿瘤多为良性,手术全切除即能根治。脑肿瘤手术因手术器械的进步而有较大进展。良性肿瘤一般可以手术根治,如果良性肿瘤在颅内与颅动脉粘连,或在视丘下浸润重要组织,有硬性粘连,不能全切除,可考虑肿瘤生长速度,术后与放疗。如果剥离时有功能损伤,可作次全切除。脑实质的神经胶质瘤浸润生长,几乎不可能行全切除,手术目的尽量切除肿瘤组织,颅内减压,或为确诊决定治疗方法等。不同治疗方式的五年生存率
In Japan, there are about 12,000 brain cancer patients each year, with a prevalence of 10/10 million. Most of the brain parenchymal tumor is malignant infiltrative proliferation, total resection of the eye surgery is also easy to relapse; mostly extranodal tumors are benign, the total excision can cure. Brain tumor surgery has made great progress due to the progress of surgical instruments. Generally benign tumors can be radical surgery, if benign tumors in the intracranial and cranial artery adhesions, or infiltration of important tissues in the hypothalamus, a rigid adhesions, can not be fully resected, consider the tumor growth rate, postoperative and radiotherapy. If there is functional impairment when stripping, for subtotal resection. Brain parenchymal glioma infiltration growth, almost impossible to line total resection, surgical resection of tumor tissue as much as possible, intracranial decompression, or to determine the diagnosis and treatment methods. Five-year survival rates for different treatment modalities
