基于3D打印的骨盆肿瘤“三位一体”个性化治疗模式专家共识

骨盆邻近区域解剖复杂,有消化、泌尿、生殖等脏器及重要血管和神经,因此,骨盆肿瘤精准切除及切除后骨缺损精准重建极为困难。医学3D打印技术的发展为骨盆肿瘤的精准切除和个性化重建提供了新思路。3D打印个性化病变模型、截骨导板和重建假体"三位一体"在骨盆肿瘤切除与保肢重建中的应用,取得了良好的临床效果。但目前缺乏针对3D打印个性化骨盆肿瘤模型、截骨导板和重建假体设计、制备流程及应用的规范性指导标准,制约了其推广应用。本共识的制定旨在为基于3D打印的"三位一体"个性化治疗模式在骨盆肿瘤保肢重建中的应用提供规范性指导。

Expert Concensus on Triune Personalized Treatment of Pelvic Tumor Based on Three-Dimensional Printing

The adjacent anatomy of the pelvis is complicated,with digestive,urinary,reproductive and other organs as well as important blood vessels and nerves. Therefore,accurate resection of pelvic tumors and precise reconstruction of defects after resection are extremely difficult. The development of medical three-dimensioal( 3D) printing technology provides new ideas for precise resection and personalized reconstruction of pelvic tumors. The ‘triune ’ application of 3D printing personalized lesion model, osteotomy guide plate and reconstruction prosthesis in pelvic tumor limb salvage reconstruction treatment has achieved good clinical results.However,the current lack of normative guidance standards such as preparation and application of 3D printing personalized lesion model,osteotomy guide plate and reconstruction prosthesis restricts its promotion and application. The formulation of this consensus provides normative guidance for 3D printing personalized pelvic tumor limb salvage reconstruction treatment.
