原发性脊柱肿瘤相对少见,约占所有脊柱肿瘤的20%,全身骨肿瘤的6.6%~8.8%~([1])。尽管原发性脊柱肿瘤的诊治原则与四肢骨肿瘤基本相同,但由于脊柱解剖复杂,毗邻脊髓神经、大血管及重要脏器结构,其外科切除难度较大、风险较高,既往多采用次全切除方式,局部复发率居高不下,治疗效果远不如四肢骨肿瘤。近20年来,随着脊柱外科技术的不断进步、脊柱内固定与重建器械的飞速发展及肿瘤学认识的逐步融入,脊柱肿瘤的治疗由过去的简单椎板切除、减压到现在的全脊椎切除,由过去的分块切除到现在的整块切除,使得脊柱肿瘤的临床疗效明显提高。
Primary spine tumors are relatively rare, accounting for about 20% of all spine tumors and 6.6% ~ 8.8% of whole body bone tumors. [1] Although the principle of diagnosis and treatment of primary spinal tumors and limb bone tumors are basically the same, but due to complex anatomy of the spine, adjacent to the spinal cord nerves, blood vessels and important organs structure, surgical resection is more difficult and higher risk, Excision, the high rate of local recurrence, the treatment is far less effective than limb bone tumors. In recent 20 years, with the continuous progress of spine surgery, the rapid development of spinal internal fixation and reconstructive instruments and the gradual integration of oncology knowledge, the treatment of spinal tumors has been reduced from the simple laminectomy in the past to the current total spondylectomy , Removed from the previous block to the present block, making the clinical efficacy of spinal tumors significantly improved.
