To compare the difference of preoperative planning parameters between 3D-printing non-coplanar template (3D-PNCT) and 3D-printing coplanar template (3D-PCT) in the treatment of pelvic wall recurrent gynecological malignant tumor with radioactive seeds implantation, and to guide the clinical application. From January 2016 to March 2018, 33 patients with pelvic wall recurrent gynecological malignant tumor were treated with radioactive seeds implantation assisted by 3D-printing template and in Peking University Third Hospital. All patients underwent 3D-PNCT and 3D-PCT preoperative planning. The D(90) of target remained similar for the same patient. The parameters were compared with test or test. D(90) was similar between the two groups (0.05). The number of inserting needles through intestine and bone in 3D-PNCT group was less than that in 3D-PCT group (0 (0-13), 0 (0-25), 2.941, 0.05;0 (0-3), 0 (0-25), 2.232, 0.05). For patients with gynecological malignancies with pelvic recurrence, both of the two peroperative plans could achieve prescription dose, but 3D-PNCT is more safer.
比较三维打印非共面模板（3D-PNCT）与三维打印共面模板（3D-PCT）在放射性粒子植入治疗盆腔壁复发性妇科恶性肿瘤中的术前规划参数差异，以指导临床应用。2016年1月至2018年3月，北京大学第三医院对33例盆腔壁复发性妇科恶性肿瘤患者采用三维打印模板辅助放射性粒子植入治疗。所有患者均进行了3D-PNCT和3D-PCT术前规划。同一患者靶区的D(90)保持相似。采用t检验或秩和检验比较参数。两组间D(90)相似（P>0.05）。3D-PNCT组经肠和经骨穿刺针数均少于3D-PCT组（0（013），0（025），t=2.941，P<0.05；0（03），0（025），Z=2.232，P<0.05）。对于盆腔复发的妇科恶性肿瘤患者，两种术前规划均能达到处方剂量，但3D-PNCT更安全。
