恶性骨肿瘤保肢治疗的原则及问题

保肢手术已成为治疗肢体恶性骨肿瘤的经典方法。保肢治疗的目的是不但要提高患者的生存率，而且要保存良好的肢体功能。保肢手术的第一个目的是避免局部复发，第二个目的是尽可能多地保留功能。治疗格言为：“肿瘤第一，功能第二”。国内近20年来骨肿瘤的治疗已经取得了很大的进步，     

骨关节假体在四肢恶性骨肿瘤保肢手术中的应用

随着有效的新辅助化疗在临床治疗中的广泛应用，大大减少了恶性骨肿瘤的转移，提高了患者的5年生存率，从而为保肢手术提供了强有力的保证，保肢手术已经成为四肢恶性骨肿瘤的规范治疗方式。保肢手术应确保局部复发率不比截肢手术高，并且可以产生良好的功能结果。因此，术中必须对肿瘤进行广泛切除，但这样往往会造成严重的骨关节缺损。人工骨关节假体置换术是目前保肢术中重建骨关节的完整性，保留肢体功能的最有效的方法之一。     

Functional outcome of limb salvage surgery with mega-endoprosthetic reconstruction for bone tumors

Background

The use of a mega-endoprosthesis has become the method of choice for reconstruction after bone tumors. In this study, we sought to determine the functional outcome and complications associated with mega-endoprosthesis.

Methods

A retrospective review of the charts of 16 patients who had undergone resection of bone tumors followed by reconstruction with mega-endoprosthesis between 2006 and 2011 was performed. Functional evaluation was based on the Musculoskeletal Tumor Society (MSTS) scoring system. Complications of the procedures were also analyzed.

Results

Eight men and eight women at an average age of 36.7?years were included in the study. The tumor involved lower limb in 14 patients and upper limb in 2 patients. The average MSTS functional score was 72.3?±?15. Excellent results were achieved in six patients, good in five, moderate and fair in two each and poor in one. Complications occurred in eight patients. Two patients had aseptic loosening of the femoral component of total knee replacement. Flap necrosis occurred in two patients, both of whom required latissimus dorsi free flap for coverage of total knee prosthesis. One patient underwent revision of femoral component subsequent to knee dissociation. Local recurrence of tumor, patellar tendon rupture and foot drop occurred in one patient each.

Conclusion

Mega-endoprosthetic reconstruction in limb salvage provides good functional outcome in patients with bone tumors.     

Periacetabular limb salvage for malignant bone tumours

PURPOSE: To evaluate treatment outcomes in primary malignant periacetabular bone tumour removal and limb salvage with or without bone-graft reconstruction. METHODS: A total of 13 patients were treated for malignant periacetabular bone tumours at Siriraj Hospital, Bangkok, Thailand. The diagnoses were chondrosarcoma (n=8), Ewing's sarcoma (n=2), osteosarcoma (n=1), well-differentiated osteosarcoma (n=1), and malignant giant cell tumour (n=1). 11 patients did not undergo reconstruction following tumour resection; 2 patients received fibular bone grafts bridging the periacetabulum to the remaining sacrum. Adjuvant chemotherapy was administered for high-grade malignant tumours, and postoperative radiation therapy was performed on patients with a closed surgical margin. RESULTS: At a mean follow-up of 24.3 months (range, 8.9-43.9 months), 9 patients remained disease-free, 3 had died of the disease, and one was alive with disease. According to the Musculoskeletal Tumor Society classification system, the mean functional analysis at final follow-up was 68.7%. Patients who underwent internal hemipelvectomy experienced a subsequent leg-length discrepancy ranging from 3 to 10 cm. Four patients had complications (one each for deep wound infection, skin necrosis, seroma, and vascular spasms) and were successfully treated with multiple debridements and appropriate antibiotics. Three patients had local recurrences; one required a classic hemipelvectomy. CONCLUSION: Malignant periacetabular tumours are difficult to manage. Functional results of our patients with no reconstruction or with bone-graft bridging were fair. Patients undergoing internal hemipelvectomy may experience leg-length discrepancies, which can be balanced with shoe lifts.     

Limb salvage in primary malignant bone tumors

Advances in adjuvant chemotherapy and improvements in techniques of oncologic reconstruction have stimulated renewed interest in limb saving operation for malignant bone tumors. Between 1970 and 1981, 160 patients underwent local resection for malignant osseous lesions at the Mayo Clinic. This included 102 patients with chondrosarcoma, 44 with osteosarcoma, and 14 with fibrosarcoma. Ninety-three of the lesions were stage I and 67 were stage II. The overall local recurrence rate was 11.8%. The reconstructive procedures were effective in providing adequate functional restoration. Limb sparing operation is a valid viable option in carefully selected patients with malignant bone tumors. A continued search for effective adjuvant treatment programs is necessary.     

Infection in limb salvage surgery for bone tumors

The authors present a retrospective study of 66 infected cases in their series of limb salvage surgery performed from January 84 to August 92. Special emphasis was given to the alternative techniques of treatment in infection. In 85% of the cases healing was achieved, however removal of the implant and amputation are still frequent occurrences. Time to recovery is very demanding.     

The UCLA experience in limb salvage surgery for malignant tumors

Between December 1980 and January 1985, 95 patients with 98 malignant bone tumors were treated at UCLA by a multidisciplinary approach. Seventy-eight patients with 81 lesions underwent primary limb salvage procedures utilizing 66 custom endoprostheses and, in 15 instances, soft tissue reconstruction alone. Sixty-three of 78 (80.7%) underwent successful limb salvage without complication. The 22 local complications in 15 patients (19.2%) were all successfully managed either by surgical or nonoperative techniques salvaging all 15 extremities at risk. Seventeen patients underwent primary amputation for local control of their tumor. The local recurrence rate of 6.4% in the limb salvage group is comparable to the 5.8% found in the amputation group. The selection of patients for limb salvage did not adversely prejudice these patients in terms of rates of progression or ultimate survivorship. The cosmetic and functional results of limb sparing surgery is felt to be at least comparable with that obtained by primary amputation and the use of external prostheses.     

Low dose irradiation for limb salvage in malignant bone tumours

Summary We have assessed the value of adding low dose radiotherapy to preoperative chemotherapy in 20 patients with high grade malignant bone tumours. Histology of the resected specimens showed a considerable tumouricidal effect and a distinct capsule enclosing the extraosseous part of the tumour. There were no serious side effects.

---

Résumé Nous avons étudié sur le plan clinique et anatomo-pathologique, chez 20 malades atteints de tumeurs osseuses de haut degré de malignité, la valeur de la radiothérapie à la dose de 30 Gy en complément de la chimiothérapie pré-opératoire. L'histologie des pièces réséquées chirurgicalement a montré un effet tumoricide considérable et l'encapsulement de la partie extra-osseuse de la tumeur. La radiothérapie n'a pas déterminé d'effets secondaires fâcheux. Elle paraît donc indiquée pour la conservation des membres en cas de tumeurs osseuses de haut degré de malignité.

     

恶性骨肿瘤保肢手术并发症的原因及防治

目的探讨恶性骨肿瘤保肢手术并发症发生的原因及防治措施.方法采用微波原位灭活术和人工假体置换术对66例膝关节周围恶性肿瘤患者行保肢术,微波原位灭活38例,人工膝关节置换28例.在复习病历的基础上分析其手术并发症.结果微波原位灭活组随访11～67个月,平均29.6个月,其中12例死亡,3年生存率为65.8%;6例因感染、肿瘤局部复发等原因而截肢,保肢率为84.2%;出现了22例次不同种类的并发症,发生率为57.9%.人工膝关节置换组随访17～62个月,平均34.8个月,其中8例死亡,3年生存率为71.4%;2例因肿瘤局部复发而截肢,保肢率为92.9%;出现了9例次不同种类的并发症,发生率为32.1%.结论恶性骨肿瘤保肢术后局部复发率不高,但肺转移发生率较高并成为恶性骨肿瘤复发致死的主要原因.切口感染多发生在胫骨上端.微波原位灭活骨段骨折多发生于术后8～16个月.除局部复发和远处转移外,人工膝关节置换组的并发症发生率低于微波原位灭活组(P＜0.05).
