[摘要] 目的 介绍CT或B超引导下碘125粒子永久植入治疗淋巴结转移或淋巴瘤所致淋巴结肿大的技术方法并评价其临床价值。方法 31例恶性肿瘤转移淋巴结，8例淋巴瘤行CT或B超引导下碘125粒子植入，依据植入前1周内CT图像应用计算机治疗计划系统制定粒子植入计划，按计划在CT或B超引导下穿刺植入碘125粒子，术后4～6个月内复查CT观察粒子分布及疗效。结果 根据疗效评价标准判定，完全缓解(CR)38.46%(15/39)；部分缓解(PR)48.71%(19/39)；无变化(AC)7.69%(3/39)；恶化(PD)5.12%(2/39)。总有效率(CR+PR)为87.18%(34/39)，未见严重并发症和治疗相关的放射损伤。 结论 碘125粒子永久植入治疗转移淋巴结及淋巴瘤是一种安全、可靠，疗效显著的治疗方法。

    [Abstract]Objective To introduce the clinical value of the treatment for lymphadenopathy due to m alignant metastatic carcinoma of lymph node or lymphoma using the method of implantation with I125 under the guidance of CT or ultrasonic. Methods According to the systemic implantation plant on the basis of the previous week CT records, 31 patients of m alignant lymph nodes and 8 patients of lymphoma were implanted I125 under the guidance of CT or ultrasonic. All the patients had CT-review four or six month after the surgery to observe I125-distribution and evaluate the effect. ResultAccording to the therapeutic effect and evaluative standard, 38.46%(15∕39) of them are completely remission, 48.71%(19/39) of them are partly remission , 7.69%(3/39) of them have no change and 5.12%(2/39) of them get degeneration. The total effect rate (CR+PR) is 87.18% (34/39) and no severe complication and no radiation injury happened during this process. ConclusionThe treatment for m alignant lymphadenovarix using the method of implantation with I125 is safe, reliable and effectively. ......
