摘　　要：骶骨和骨盆环处恶性肿瘤的保肢治疗具有相当的挑战性，该部位解剖毗邻关系复杂、存在重要脏器和神经血管等常使手术难以达到恶性骨肿瘤的外科边界。恶性肿瘤一旦侵及骶髂关节，手术过程中需要将肿瘤组织包括骶髂关节一并切除，同时重建骨盆环的完整性，必将增加手术的难度。Objective To investigate the possibility of clinical application of en bloc resection of primitive neuroectodermal tumor （PNET） involving the sacroiliac .joint and reconstruction of the pelvic ring. Methods 1 female patient with PNET involving the sacroiliac joint was treated in our hospital in February 2009. She underwent 2 cycles of preoperative chemotherapy and 1 cycle of radiotherapy as the diagnosis was made by preoperative puncture. And then she received en bloc resection and reconstruction of the pelvic ring under general anesthesia. Postoperatively she accepted 10 cycles of chemotherapy. Results No recurrence and metastasis was found during the postoperative follow- up of 36 months, and she recovered to normal now. Conclusions It is particularly challenging to treat the patients with malignant bone tumors involving the sacroiliac joint because of the complicated anatomy of tumors and some other problems. However, it is possible to perform en bloc resection of tumors as long as the comprehensive methods such as preoperative chemotherapy, radiotherapy and so on are used and the therapy procedure of malignant bone tumors is strictly followed.
