The Australia and New Zealand Sarcoma Association established the Sarcoma Guidelines Working Party to develop national guidelines for the management of Sarcoma. We asked whether surgery at a specialised centre improves outcomes. A systematic review was performed of all available evidence pertaining to paediatric or adult patients treated for bone or soft tissue sarcoma at a specialised centre compared with non-specialised centres. Outcomes assessed included local control, limb salvage rate, 30-day and 90-day surgical mortality, and overall survival.

Definitive surgical management at a specialised sarcoma centre improves local control as defined by margin negative surgery, local or locoregional recurrence, and local recurrence free survival. Limb conservation rates are higher at specialised centres, due in part to the depth of surgical experience and immediate availability of multidisciplinary and multimodal therapy. A statistically significant correlation did not exist for 30-day and 90-day mortality between specialised centres and non-specialised centres. The literature is consistent with improved survival when definitive surgical treatment is performed at a specialised sarcoma centre.

Evidence-based recommendation: Patients with suspected sarcoma to be referred to a specialised sarcoma centre for surgical management to reduce the risk of local recurrence, surgical complication, and to improve limb conservation and survival.

Practice point: Patients with suspected sarcoma should be referred to a specialised sarcoma centre early for management including planned biopsy.

Aims

We present a retrospective review of patients treated with extracorporeally irradiated allografts for primary and secondary bone tumours with the mid- and long-term survivorship and the functional and radiographic outcomes.

Summary Statement

The stable inhibition of miR-214 in the aged osteoporotic rats induced by OVX could be achieved by periodic administration of AntagomiR-214 at a dosage of 4 mg/kg and at an interval of 7 days, which will provide a potential bone anabolic strategy for treatment of osteoprosis.

Aim

To review the first 50 cases, looking at survivorship of the irradiated autograft, complications and functional outcomes in a wide range of bony malignancies and anatomical locations.

Aim: To clinically and radiologically review our first 50 cases of treatment of malignant bone tumours by extra-corporeal irradiation (ECI) and re-implantation and review the world literature’s other 100 such cases.

Methods: We have treated 50 patients with bony malignancy by en bloc resection, ECI with 50Gy and reimplantation of the bone segment as a method of limb salvage. Mean survivor follow-up is 38 months (12–92).

Results: 42 patients remain alive without disease. 4 recurrences occurred. Functional results were generally good: Mankin grades 17 excellent, 13 good, 9 fair, 3 failures; MSTS mean 77 (20–100); TESS mean 81 (40–100). Solid bony union was the norm, however bone resorption was seen in some cases.

Discussion: The dose of radiation is theoretically lethal to all cells and produces a dead autogenous bone graft of perfect fit. ECI is a useful technique of limb salvage where there is a reasonable residual bone stock. It allows effective re-attachment of muscle tendons, and produces a lasting biological reconstruction. The risk from the re-implanted bone of both local recurrence and of late radiotherapy induced malignancy should be nil.

We treated 50 patients with bony malignancy by en-bloc resection, extracorporeal irradiation with 50 Gy and re-implantation of the bone segment.

The mean survivor follow-up was 38 months (12 to 92) when 42 patients were alive and without disease. There were four recurrences. The functional results were good according to the Mankin score (17 excellent, 13 good, nine fair, three failures), the Musculoskeletal Tumour Society score (mean 77) and the Toronto Extremity Salvage score (mean 81). There was solid union, but bone resorption was seen in some cases. The dose of radiation was lethal to all cells and produced a dead autograft of perfect fit.

Extracorporeal irradiation is a useful technique for limb salvage when there is reasonable residual bone stock. It allows effective re-attachment of tendons and produces a lasting biological reconstruction. There should be no risk of local recurrence or of radiotherapy-induced malignancy in the replanted bone.
