目的探索伽玛刀治疗松果体区肿瘤的具体方法,进一步提高其疗效。方法使用伽玛刀治疗松果体区肿瘤42例,肿瘤边缘剂量10～15Gy,平均14.1Gy;中心剂量24～37.5Gy,平均30.2Gy。随访4个月～3年。结果肿瘤消失19例,明显缩小13例,缩小7例,肿瘤不变3例,均无特殊并发症。结论伽玛刀是治疗松果体区肿瘤的一种安全有效的方法,对有明显梗阻性脑积水者,可先行脑脊液分流术再行伽玛刀治疗。
Objective To explore the specific method of gamma knife treatment of pineal region tumors to further improve its efficacy. Methods Forty-two patients with pineal tumor were treated with gamma knife. The tumor marginal dose was 10-15 Gy with an average of 14.1 Gy. The median dose was 24-37.5 Gy with an average of 30.2 Gy. Follow-up of 4 months to 3 years. Results 19 cases of tumor disappeared, significantly reduced in 13 cases, reduced in 7 cases, unchanged in 3 cases, no special complications. Conclusion Gamma Knife is a safe and effective method for the treatment of tumors in the pineal region. For those with obvious obstructive hydrocephalus, gamma knife may be used after the cerebrospinal fluid shunt.
