立体定向放射外科是垂体腺瘤的重要治疗方法之一,本治疗尚无明确的禁忌症;治疗方式要求精确包绕肿瘤组织;对于不同的垂体腺瘤要采用不同的剂量标准,如果控制肿瘤的生长,一般使用10-15Gy的周边剂量;如果控制激素的分泌,一般使用25-35Gy的周边剂量。不同的肿瘤采用的周边剂量范围也不相同,GH腺瘤一般采用25-30Gy,PRL腺瘤一般采用16-35Gy,ACTH腺瘤主张采用35Gy;最新的研究表明视通路的安全剂量10-12Gy之间;对激素分泌的控制在83％以上,对肿瘤生长的控制在91％以上。
Stereotactic radiosurgery is one of the important treatment of pituitary adenomas, the treatment is no clear contraindication; treatment requires precise wrap around the tumor tissue; for different pituitary adenomas to use different dosage standards, if the control of the tumor Growth, the general use of 10-15Gy peripheral dose; if the control of hormone secretion, the general use of 25-35Gy peripheral dose. Peripheral dose range for different tumors are not the same, GH adenoma usually 25-30Gy, PRL adenoma generally use 16-35Gy, ACTH adenoma 35Gy advocate; the latest study shows that the safe dose of access pathway 10-12Gy Between the control of hormone secretion in more than 83%, the control of tumor growth in more than 91%.
