[目的]分析立体定向伽玛射线全身治疗系统(超级伽玛刀)治疗体部恶性肿瘤的近期疗效。[方法]体部恶性肿瘤患者318例(其中经病理证实284例),采用超级伽玛刀治疗,肿瘤直径<3cm者,用70%～90%的等剂量曲线覆盖靶区,单次周边剂量4～6Gy,总剂量35～50Gy;肿瘤直径3～5cm者,用60%～70%等剂量曲线覆盖靶区,单次周边剂量3～6Gy,总剂量35～45Gy;肿瘤直径>5cm者,用50%～60%等剂量曲线覆盖靶区,单次周边剂量3～6Gy,总剂量25～42Gy。一般分6～15次,每日或隔日治疗1次。[结果]CT示CR95例(29.9%),PR186例(58.5%),NC12例(3.8%),总有效率88.4%。提高生存质量,无严重毒副反应和并发症。[结论]超级伽玛刀治疗体部肿瘤症状改善明显,近期疗效显著,是体部恶性肿瘤患者的一种较为理想的治疗方法。
[Objective] To analyze the short-term curative effect of stereotactic gamma ray system therapy (super gamma knife) on malignant tumors of the body. [Method] A total of 318 patients with malignant tumors of the body (including 284 patients confirmed by pathology) were treated with hyper gamma knife. The tumor diameter was less than 3cm. The target area was covered with an equal dose curve of 70% -90% 4 ~ 6Gy, the total dose of 35 ~ 50Gy; tumor diameter of 3 ~ 5cm, with 60% to 70% isodose curve covering the target area, a single peripheral dose of 3 ~ 6Gy, a total dose of 35 ~ 45Gy; The target area was covered with an isodose curve of 50% -60% with a single peripheral dose of 3-6 Gy and a total dose of 25-42 Gy. Generally 6 to 15 times, daily or every other day treatment. [Results] CT showed CR95 cases (29.9%), PR186 cases (58.5%) and NC12 cases (3.8%), the total effective rate was 88.4%. Improve quality of life, no serious side effects and complications. [Conclusion] The super gamma knife treatment of body tumors significantly improved the symptoms, the recent significant effect, is an ideal treatment for patients with malignant tumors.
