目的探讨CT导向下放射性125Ⅰ粒子组织间植入治疗晚期上颌窦癌的可行性、疗效和副反应.方法对于28例不愿意手术和放疗的晚期上颌窦癌患者,局部浸润麻醉后在CT导向下实施125Ⅰ粒子植入术.结果 28例中完全缓解23例(82%),部分缓解4例(14%),疾病稳定1例(3%),有效率96%,疼痛缓解率76%.结论CT导向下实施125Ⅰ粒子植入术是治疗晚期上颌窦癌的一种安全、有效、微创的姑息性治疗方法.
Objective To investigate the feasibility, efficacy and side effects of CT-guided radioactive iodine 125I implantation in advanced maxillary sinus cancer.Methods Twenty-eight patients with advanced maxillary sinus cancer who did not want surgery and radiotherapy were treated with CT guided The results of 125 I seed implantation were retrospectively analyzed.Results Twenty-eight patients were relieved completely in 23 patients (82%), partially relieved in 4 patients (14%) and stable in 1 patient (3%), with an effective rate of 96% and a pain relief rate of 76%. CT-guided 125 I-particle implantation is a safe, effective and minimally invasive palliative treatment for advanced maxillary sinus cancer.
