脑瘤治疗以手术为主,但放射治疗也占重要地位。許多脑瘤难以全部切除,例如神經胶质瘤即边緣不清且具有浸潤性,故术后补加照射。又如脑干瘤由于解剖部位关系,手术时即使仅作活检也常很危险,而只能用放射治疗。此外,如髓母細胞瘤,恶性度和放射敏感性均很高,术后照射每視为常規。Boachafd氏(1960)和許多其他作者都认为 Brain tumor treatment mainly surgery, but radiation therapy also occupies an important position. Many brain tumors difficult to remove, such as glioma that is marginal and invasive, so additional postoperative irradiation. Another example is the brain stem tumor due to anatomy, surgery, even if only for biopsy is often very dangerous, but only with radiation therapy. In addition, such as medulloblastoma, high degree of malignancy and radiosensitivity are high, postoperative exposure is considered routine. Boachafd’s (1960) and many other authors agree
