研究目的: |
恶性骨肿瘤的传统治疗方法就是截肢。从截除肢体到保存肢体,是近40年来,这一领域的重大进展。在西方国家最基本的一条原则就是:将荷瘤骨切除弃之不用,遗留的缺损用人工的金属、塑料等制成的假体置换。这种方法确实保留了不少的肢体,最大优点为可早期负重,是国内外沿用的主要方法。但金属假体置换保肢术,有着先天的固有缺陷:①模拟式假体关节与人的正常关节功能不可比拟;②非生物材料和宿主骨永远不能融为一体,远期会松动;③肌肉肌腱不可能附着于假体上,而发挥最大的作用;④远期并发症: 非生物材料随着时间的延长会造成磨损,松动,不少病例需重新置换;⑤某些特殊的部位,如骨盆、胫骨远端,肩胛骨等处,假体置换问题更多,几乎没有一种令人满意的成熟方法。⑥价格昂贵,很多患者支付困难。大量文献报导,十年后就有65%以上的假体无法继续使用。更长时间松动率几乎未有报导, 肯定会更高。恶性骨肿瘤患者多为青少年,一生不知要经历多少次返修手术和再次置换, 更不要谈如何进行第三次以上的再置换手术!不少人面临二次截止的风险。 为了克服人工假体置换的上述缺点,西安第四军医大学唐都医院全军骨肿瘤研究所从1992年7月开创了一种全新的治疗体系,即微波原位灭活保肢术。它的基本原理是将荷瘤骨段从周围正常组织进行细致的手术分离(对于全身各部位的肿瘤均有一整套程序化的分离方式),然后向肿瘤内输入高能电磁波,使肿瘤自身因分子振动而产热,经过热凝固,杀灭所有的肿瘤细胞。然后根据骨质被破坏的严重程度不同采取一系列的灭活骨的加固强度措施,达到保肢的目的。这样患者邻近的大关节结构得以完整的保留,近远期并发症发生率显著降低,患者肢体功能得以最大限度保留。 |

Objectives of Study: |
Limb salvage surgery for patients with malignant bone tumors mainly consists of two parts: en bloc resection of the tumor-bearing bone and followed reconstruction for the remained defect. Now, majority of large centers in the world are in favor of metallic endoprostheses replacement. Endoprostheses survival rates now exceed 85% at 5 years for reconstruction about the knee. The aseptic loosening at a specified future date is a main concern, the prosthesis survival rate reduced to 35% at 10 years after surgery. The inherent problems are related to the materials used. The anchorage of metallic parts to bone and to soft tissues is especially a poorly solved problem. For young patients, the implantation of artificial material will have to stand wear and tear for decades. So much work, such as improving the prosthesis design and the materials used, have been done to make the results better but no big improvement. Ablation of the tumors in situ is another way to promote the long-term results: instead of en-bloc resection of tumor- bearing bone, only dissect it from surrounding normal tissues, then devitalize the bone segment by microwave induced hyperthermia in situ。 Main Concept & Method - The main concept here is to achieve a safe margin tumor en bloc ablation (assuming that the tumor is localized in the region of diagnosis) using antenna-guided hyperthermia therapy. Currently, co-axial MW antennas (require circulating water to cool the tip of the antenna from metal melting damage due to high temperature) inserted into the carefully dissected and isolated tissue block enveloping the tumor inflicted and as well the adjacent normal tissues. From our preliminary animal and model studies, all tissues including the underlying bone and marrow will be completely devitalized (cell death and protein denatured) after heated to 70-80°C or higher for at least 20 minutes. During surgery, multiple thermocouples were placed in various critical locations to monitor the temperature within and around the bulk. These died tissues were removed and/or curetted leaving behind the defective bone for reconstruction using any of the currently accepted methods, materials (autograft, allograft) and implants. If the traditionally defined wide margin could be identified using en bloc resection technique, MW ablation can achieve a similar goal while retaining the curetted cortical bone intact, thus making reconstruction easier and more durable. In this way, the structures of the adjacent natural joint were salvaged well. The function was greatly improved. The devitalized bone should act as a bridge for creeping substitution and incorporation thereby providing the chance of a lifelong biological solution. Of course, special attention will be paid to protect the vital tissue and organ such as cartilage, tendons, ligaments, nerves and the spinal cord. |

随机方法(请说明由何人用什么方法产生随机序列): |
因为恶性骨肿瘤是罕见疾病,很难进行随机分组。只能把得到的结果与文献上发表的别种治疗方法的结果进行对比。 |

|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Because malignant bone tumors are rare lesion, it is difficult to make a control group to randomize the study and only compare the results with those of other therapies published in the literature |
