摘 要:目的评价立体定向囊内放疗治疗囊性颅咽管瘤患者的远期疗效。方法回顾性纳入1996年1月至2015年12月在海军总医院神经外科行立体定向囊内P-32放射治疗的囊性颅咽管瘤患者141例,其中67例(47.5%)为术后复发者。囊壁累计计算的B射线照射剂量为250Gy。评估患者的远期治疗结果。结果随访1.0-19.5年,平均(9.7±4.5)年。视力下降的改善率为68.6%(59/86)。141例患者中,肿瘤的有效控制率为86.5%(122例),其中完全有效率为44.0%(62例),部分有效率为36.2%(51例),稳定率为6.3%(9例);无效率为13.5%(19例);肿瘤复发率为17.0%(24例)。141例中,随访期发生视力下降13例(9.2%),动眼神经麻痹2例(1.4%),颈内动脉闭塞1例(0.7%),新发性功能障碍5例(3.5%)、多饮多尿7例(5.0%)、肥胖12例(8.5%)、记忆力或认知功能下降10例(7.1%),远期总体并发症的发生率为35.5%(50/141)。平均生存时间为120个月,5年、10年及15年实际生存率分别为97.9%(138/141)、92.9%(131/141)及89.3%(126/141)。结论立体定向囊内放射治疗囊性颅咽管瘤,长期疗效较好。适用于手术风险高和术后复发的患者。Objective To assess the long-term outcomes of stereotactic intracystic brachytherapy for the treatment of cystic craniopharyngiomas. Methods A total of 141 consecutive patients with cystic craniopharyngioma treated by stereotactic intracystic phosphorus-32 at Department of Neurosurgery, Navy General Hospital of PLA from January 1996 to December 2015. There were 85 males and 56 females and the mean age was 40. 1 years (range: 3 -72 years). The calculated cumulative beta dose aimed at the inner surface of the cyst wall was 250 Gy. Results All patients were followed up for 1.0 - 19.5 years with an average of 9.7 ± 4.5 years. The decreased visual acuity had improved in 68. 6% (59/86) of the patients in long-term result. The total tumor response rate was 86.5% (122 cases) including the total response accounting for 44.0% (62 cases), partial response accounting for 36.2% (51 cases) and stable response accounting for 6. 3% (9 cases). The rate of no response was 13.5% ( 19 cases). The recurrence rate was 17% (24 cases). The side effects that occurred during follow-up period included worsening of visual acuity in 13 (9.2%), the third nerve palsy in 2 ( 1.4% ), internal carotid artery occlusion in 1(0.7%), new-onset sexual dysfunction in 5 (3.5%), diabetes insipidus in 7 (5.0%), obesity in 12 (8.5%) and cognitive dysfunction in 10 (7. 1% ) patients, respectively. The late complication rate was 35.5% (50/141). The mean survival after treatment was 120 months. The actuarial 5-, 10- and 15-yr survival rates were 97.9% (138 cases), 92.9% (131 cases) and 89.3% (126 cases), respectively. Conclusion Stereotactic intraeavitary brachytherapy is a valuable treatment alternative for cystic craniopharyngiorna, particularly for patients with high surgical risk and recurrent tumors.
