目的 探讨术前TPS及术后质量验证在125I粒子近距离治疗眼眶肿瘤中的作用.方法 对2005年4月至2009年12月期间66例行125I粒子近距离治疗的眼眶肿瘤患者资料进行回顾性分析.66例中43例有数字影像资料者术前应用TPS,处方剂量140 Gy;余23例患者未行术前TPS,术中按间隔1 cm原则平行排列粒子.对所有66例患者术后均应用TPS进行质量验证.术后3、6、12和24个月分别对患者进行CT和(或)MRI随访.采用SPSS 17.0软件进行x2检验及Kaplan-Meier法log-rank 检验.结果 66例患者共植入125I粒子1070粒,平均(16.2±7.3)粒/人.TPS术前计划组及未计划组术后质量验证满意率分别为79.07%( 34/43)及43.48%( 10/23),差异有统计学意义(x2=8.542,P=0.003).10例患者术后失访,仅有术后验证资料,无影像学随访资料.TPS质量验证满意组术后3、6、12和24个月肿瘤局部复发率分别为0(0/37)、6.25% (2/32)、13.64% (3/22)和3/9,TPS质量验证不满意组局部复发率分别为5.26% (1/19)、16.67% (3/18)、30.77% (4/13)和6/6,2组间差异有统计学意义(x2=9.017,P=0.0003).结论 TPS在125I粒子近距离治疗眼眶肿瘤中起重要作用.术前TPS是治疗成功的前提,TPS术后质量验证能较好地预测治疗效果,并指导临床确定进一步治疗方案.

Objective To investigate the role of TPS in 125I brachytherapy for orbital tumors.Methods Sixty-six patients with orbital tumor treated with 125I seeds from 2005 to 2009 were retrospectively analyzed.Forty-three patients were treated using TPS guided brachytherapy and the prescribed dose was 140 Gy.Other 23 patients were treated without TPS but simply implanted with 125I seeds at 1 cm intervals in parallelwith each other intraoperatively.CT and TPS quality verification were performed postoperatively in all patients.Also,CT and (or) MRI examination were performed at 3,6,12 and 24 months after brachytherapy for follow-up.x2 test and Kaplan-Meier survival analysis with log-rank significance test were used with SPSS 17.0.Results A total of 1070 125 I seeds were implanted in 66 cases,on average,( 16.2 ± 7.3) seeds for each patient.The satisfaction rates of postoperative quality verification in patients with and without TPS preplans were 79.07% (34/43) and 43.48% (10/23) respectively (x2 =8.542,P =0.003 ).Ten patients were lost in follow-up.Local recurrence rates in patients with favorable postoperative quality verification were 0(0/37) in 3 months,6.25% (2/32) in 6 months,13.64% (3/22) in 12 months and 3/9 in 24 months respectively,which were significantly different from those (5.26% (1/19),16.67% (3/18),30.77% (4/13),6/6 )in the patients with inferior postoperative quality verification (x2 =9.017,P =0.0003).Conclusions TPS plays an important role in 125I brachytherapy for orbital tumors.Also,postoperative quality verification by TPS may help predict the local recurrence after brachytherapy.
