Aims

The existing clinical guidelines do not describe a clear indication for adjuvant radiotherapy (RT) in the treatment of superficial soft tissue sarcomas (STSs). We aimed to determine the efficacy of adjuvant RT for superficial STSs.

Aim

We present the long-term surgical outcomes, complications, implant survival and causes of implant failure in patients treated with the modified Harrington procedure using antegrade large diameter pins.

Aims

The purpose of this study was to review a large cohort of patients and further assess the correlation between the histological response to chemotherapy in patients with Ewing’s sarcoma with the overall (OS) and event-free survival (EFS).

Bone sarcomas are rare cancers and orthopaedic surgeons come across them infrequently, sometimes unexpectedly during surgical procedures. We investigated the outcomes of patients who underwent a surgical procedure where sarcomas were found unexpectedly and were subsequently referred to our unit for treatment. We identified 95 patients (44 intra-lesional excisions, 35 fracture fixations, 16 joint replacements) with mean age of 48 years (11 to 83); 60% were males (n = 57). Local recurrence arose in 40% who underwent limb salvage surgery versus 12% who had an amputation. Despite achieving local control, overall survival was worse for patients treated with amputation rather than limb salvage (54% vs 75% five-year survival). Factors that negatively influenced survival were invasive primary surgery (fracture fixation, joint replacement), a delay of greater than two months until referral to our oncology service, and high-grade tumours. Survival in these circumstances depends mostly on factors that are determined prior to definitive treatment by a tertiary orthopaedic oncology unit. Limb salvage in this group of patients is associated with a higher rate of inadequate marginal surgery and, consequently, higher local recurrence rates than amputation, but should still be attempted whenever possible, as local control is not the primary determinant of survival.

A clinical evaluation of the effect of MRI scan to bring about a change in surgical management of elderly patients who present with hip fracture with no history of trauma or a suspicious looking lesion on x-rays. Many of these patients present with or without history of previous malignancy or bone disorder.

We evaluated that if the delay in treatment within 36 hours as per national guide lines is justified to benefit patients.

Aim

To estimate the risk of bone malignancy arising in premalignant conditions.

Introduction

The aim of this study is to evaluate the functional and oncological outcome of extracorporeally irradiated autografts as a method of pelvic reconstruction after internal hemipelvectomy.

Osteosarcomas represent a heterogeneous group of primary bone tumours that affect predominantly the long bones of patients in the first two decades of life. We aim to describe the secondary effects of a poor response (⋋90% necrosis) to chemotherapy on the effectivity of other treatment outcomes, local recurrence and survival rates.

182 cases of osteosarcoma with necrosis of less than 90% and no metastases at diagnosis have been seen at our institution over 24 years. There were 60 amputations. 122 patients underwent limb salvage, with 105 marginal margins and 17 contaminated. There was no difference in size or location between the two groups. In the 122 patients with LSS, 21 had adjuvant radiotherapy and 101 did not. In the entirety of patients with ⋋90% necrosis, survival was 64% at 2 years and 37% at 5 years. When LSS Marginal resections were compared with amputation there was a significant (P=0.006) difference in survival. LSS with a marginal margin had a 25% risk of LR. In these patients there was 25% survival, whereas the absence of a local recurrence, conferred a benefit of a 40% survival XRT was used in 21 of the 122 who underwent limb salvage. The decision to use XRT was made by the local oncologist at the treating unit. There was a 24% rate of recurrence in the XRT group and 25% with no XRT.

These data demonstrated that patients who had a poor response to chemotherapy and underwent an amputation faired poorly when compared to patients with LSS. There is a selection bias in patients selected to undergo amputation. Additionally, patients who underwent amputation had a lower rate of local recurrence, but still had a poorer survival when compared to LSS.

Introduction

The role of adjuvants in curettage for giant cell tumours (GCT) is still controversial. Our aim was to determine if adjuvant cementation lowers local recurrence (LR) rates for GCTs treated with curettage.

Aim

To investigate the effectiveness of silver coated prostheses in preventing periprosthetic infection in a high-risk group.

Introduction

Myxofibrosarcoma is described by WHO as comprising of a spectrum of malignant fibroblastic lesions with variably myxoid stoma, pleomorphism and with a distinctively curvilinear vascular pattern. They are reported to be one of the commonest sarcomas of elderly patients. It has previously been reported to have a high rate of locally recurrent disease (50-60%). The aim of the study was to investigate the ROH series of tumours to determine prognostic factors for survival and local recurrence.

The aim was to identify when primary amputation was used as primary treatment and to describe outcomes in patients managed with modern chemotherapy. A detailed review of the electronic patient records was undertaken. Statistical analysis was performed with univariate analysis using Kaplan-Meier curves and Chi² testing, whilst multivariate analysis was performed using Cox regression analysis.

There were 354 osteosarcomas. 93 patients presented with metastases and 192 subsequently developed metastases at a mean of 46 months. Amputation was performed as the primary surgical treatment in 101 patients. Endoprosthetic reconstruction was used in 253 patients. Amputation was performed as a secondary procedure on 15 patients.

The 5 and 10 year survival data for all patients, including those with metastatic disease were 60% and 60% for amputation with good chemotherapy response (>89% necrosis), 65% and 63% for limb salvage and good response, 21% and 21% for amputation and poor response (⋋90% necrosis) and 51% and 30% for limb salvage with poor response.

Local recurrence occurred both with amputation (10.8%) or limb salvage (9%), with no significant differences between the two.

Univariate analysis demonstrated that the extent of response to chemotherapy induced necrosis significantly affected survival, whether the patient had an amputation or not.

Whether or not amputation or LSS was used in the surgical management of patients, local recurrence rates where similar between the two groups. Further assessment of chemotherapy-induced necrosis is a key factor in determining subsequent limb salvage or amputation management strategies.

Chondrosarcoma of bone is a surgical disease and excision with wide margins is the optimum treatment. Sometimes the size or location of the tumour at the time of diagnosis mean that only a marginal excision can be achieved. The effect of the margin of excision on outcome is investigated.

Non-invasive expandable prostheses for limb salvage tumour surgery were first used in 2002. These implants allow ongoing lengthening of the operated limb to maintain limb-length equality and function while avoiding unnecessary repeat surgeries and the phenomenon of anniversary operations.

A large series of skeletally immature patients have been treated with these implants at the two leading orthopaedic oncology centres in England (Royal National Orthopaedic Hospital, Stanmore, and Royal Orthopaedic Hospital, Birmingham).

An up to date review of these patients has been made, documenting the relevant diagnoses, sites of tumour and types of implant used. 87 patients were assessed, with an age range of 5 to 17 years and follow up range of up to 88 months.

Primary diagnosis was osteosarcoma, followed by Ewing's sarcoma. We implanted distal femoral, proximal femoral, total femoral and proximal tibial prostheses. All implants involving the knee joint used a rotating hinge knee. 6 implants reached maximum length and were revised. 8 implants had issues with lengthening but only 4 of these were identified as being due to failure of the lengthening mechanism and were revised successfully. Deep infection was limited to 5% of patients.

Overall satisfaction was high with the patients avoiding operative lengthening and tolerating the non-invasive lengthenings well. Combined with satisfactory survivorship and functional outcome, we commend its use in the immature population of long bone tumour cases.

Aim

To identify factors leading to the success or failure of extracorporeal irradiation and re-implantation of bone (ECIR).

Aim

To determine the overall survival of patients with Pelvic Ewing's Sarcoma treated in our unit and to identify prognostic factors in pelvic primaries that could be used to select patients who would most likely benefit from high intensity treatment.

Introduction

The aim of this study was to investigate the results of a series of cases from a single institution with respect to local disease control and patient survival to determine prognostic factors.

Since1986 we have monitored the actual diagnosis of all cases referred to our Unit with the diagnosis of ‘possible primary malignant bone tumour’. We have excluded all patients referred with a known diagnosis of either a benign condition or known to have bone metastases. In most cases the suspected diagnosis was based on X-rays alone, sometimes supported by further imaging.
