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.

Methods

We retrospectively studied 304 patients with superficial STS of the limbs and trunk who underwent surgical resection at a tertiary sarcoma centre. The efficacy of RT was investigated according to the tumour size and grade: group 1, ≤ 5 cm, low grade; group 2, ≤ 5cm, high grade; group 3, > 5 cm, low grade; group 4, > 5 cm, high grade.

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).

Patients and Methods

All patients treated for Ewing’s sarcoma between 1980 and 2012 were reviewed. Of these, 293 patients without metastases at the time of diagnosis and treated with chemotherapy and surgery were included. Patients were grouped according to the percentage of necrosis after chemotherapy: Group I: 0% to 50%, Group II: 51% to 99% and Group III: 100%.

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.

Methods

A clinical review of six hundred hip fracture patients where one hundred and four patients who had MRI scan of hip for fracture with either no history of trauma or a fracture with suspected pathological features with or without history of malignancy or bone disorder.

The final outcome of hundred patients who had MRI scans 32 male and 68 female with median age of 65 years. Four patients were excluded as were unable to tolerate the MRI scan.

Statistical analysis software SAS/STAT® was used to conduct data collation and analyses.

A further radiological analysis of MRI scans with positive lesion to the plain X-rays to correlate the finding of a lesion on femoral side on MRI scan to a lesion on acetabular side.

Results

Out of hundred patients who had MRI scan for a suspected metastatic or pathological lesion only 12 showed a metastatic lesion despite the fact 31 had previous history of malignancy, CI 4.03; 101.91, P < 0.0003. No primary lesion detected in any patient.

We also found if the acetabular side was not seen to be involved on pain x-ray, MRI scan did not detect any acetabular lesion, contingency coefficient 0.5632, P < .0001.

Aim

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

Methods

There are quite a number of possible premalignant conditions with considerable uncertainty about the actual risk of a bone sarcoma developing. The incidence of these malignant conditions was identified from a prospective database containing 3000 primary bone sarcomas.

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.

Methods

Detailed curettage has been the principal treatment for GCT for the past 30 years. Cement was used from 1996 onwards for tumours where there was concern about structural stability. We investigated factors affecting LR and also the incidence of complications for treatment with or without cement.

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.

Methods

Patients were identified from the ROH database who had been treated with a new presentation of myxofibrosarcoma. The size, grade and depth of the tumour at presentation was noted. Those patients who had suffered local or distal disease relapse or died were highlighted. Analysis was undertaken by Kaplan Meier survival curves for univariate and cox regression for multivariate analysis.

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.

Method

All patients with newly diagnosed primary chondrosarcoma of bone and without metastases at the time of diagnosis were identified from a prospective database. Their outcome was investigated to assess whether the margin of excision affected outcome.

Results

492 patients were included in the analysis with a mean age of 48. The mean tumour size was 11cm and 59% were male. The 10 year tumour specific survival was 85% for clear cell (N=7) and grade 1 (N=210), 60% for grade 2 (N=180), 47% for grade 3 (N=59) and 16% for dedifferentiated (N=36). The 10 year local recurrence free survival was 86% (clear cell), 73% (grade 1), 67% (grade 2), 36% (grade 3) and 56% dedifferentiated.

Local recurrence was strongly related to older age (p=0.0065), grade (p⋋0.0001) and margins (p⋋0.0001). Patients who developed local recurrence had a 43% survival at 10 years compared with 76% for those who did not (p⋋0.0001). They also had a 49% risk of developing metastases compared to a 17% risk for those without local recurrence (p⋋0.0001). However most of these patients had metastases before developing LR(57%). 16 of 65 patients with local recurrence but no metastases, died due to local progression (usually pelvic or spinal tumours). There was however no relation of the margin of excision to either the risk of developing metastases or survival for any grade of tumour.

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 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.

Method

Between 1977 and 2009, 80 male and 66 female patients aged 2 to 60 (mean, 18) years with Pelvic Ewing's Sarcomas were retrospectively reviewed from the Royal Orthopaedic Hospital Oncology Service Registry. Treatments included surgery, radiotherapy, chemotherapy, or any of them in combination. Event-free (from presentation to recurrence) and overall (from presentation to death/latest follow-up) survival rates were calculated using the Kaplan- Meier method.

Influence of various factors (age at diagnosis, gender, tumour site, metastasis at presentation, surgery (and surgical margins), radiotherapy, and type of treatment on survival was assessed using SPSS 14.0 statistical software.

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.

Methods

Electronic patient records were reviewed on all patients with STS between February 1963 and January 2007. 2445 patients had over 30 types of STS. 1639 (67%) had not received any treatment prior to presentation, however, 770 patients (32%) had undergone a previous attempted excision. Survival analyses were done using Kaplan Meier and Cox regression analyses, however, for prognostic factor analysis, only patients presenting without prior treatment were included.

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.

Method

Retrospective review of a prospective database that was started in 1986 identifying the actual diagnosis.

Results

There were 5922 patients with a confirmed diagnosis over the 23 year time period of this study. 2205 (37%) were found to have a primary malignant bone sarcoma and 1309 (22%) had a benign bone tumour. 992 patients had a general orthopaedic condition (e.g. geode or a vascular necrosis) whilst 303 (5%) had a haematological malignancy and 289 (4.9%) infection. 533 patients (9%) had metastases. There was a similar pattern of frequency of all diagnoses except for metastatic disease and haematologic malignancy at different ages. The incidence of metastases increased from the age of 35 onwards
