近10多年来，国内外不断有人报告，对骨盆的一些原发性高分化恶性肿瘤和大范围溶骨性疾患采取病灶切除，人工半骨盆置换术，以重建骨盆环的完整和保留下肢功能，为骨盆肿瘤的治疗开避了一条新途径。我院从1990年开始对5例骨盆肿瘤采用了盆腔内血管大剂量抗癌药物局部灌注，血管 In the past 10 years, there have been reports from both home and abroad that focal resection and artificial hemipelvic replacement have been performed on some primary pelvic bones with highly differentiated malignant tumors and extensive osteolytic disease, in order to rebuild the integrity of the pelvic ring and preserve lower limb function. Treatment of pelvic tumors avoids a new approach. In our hospital, since 1990, 5 cases of pelvic neoplasms have been treated with high-dose pelvic vascular infusion of anti-cancer drugs.
