Aims. While a centralized system for the care of patients with a sarcoma has been advocated for decades, regional variations in survival remain unclear. The aim of this study was to investigate regional variations in survival and the impact of national policies in patients with a soft-tissue sarcoma (STS) in the UK. Methods. The study included 1,775 patients with a STS who were referred to a tertiary sarcoma centre. The geographical variations in survival were evaluated according to the periods before and after the issue of guidance by the National Institute for Health and Care Excellence (NICE) in 2006 and the relevant evolution of regional management. Results. There had been a significant difference in survival between patients referred from the North East, North West, East Midlands, West Midlands, South West, and Wales in the pre-NICE era (five-year disease-specific survival (DSS); South West, 74% vs North East, 47% (p = 0.045) or West Midlands, 54% (p = 0.049)), which was most evident for patients with a high-grade STS. However, this variation disappeared in the post-NICE era, in which the overall DSS for high-grade STS improved from 47% to 68% at five years (p < 0.001). Variation in the size of the tumour closely correlated with the variation in DSS, and the overall size of the tumour and incidence of metastasis at the time of diagnosis also decreased after the national policies were issued. Conclusion. The survival of patients with a STS improved and regional variation corrected after the introduction of national policies, as a result of a decreasing size of tumour and incidence of metastasis at the time of diagnosis, particularly in patients with a high-grade STS. This highlights the positive impact of national guidelines on regional variation in the presentation, management, and outcome in patients with a STS.

Aims. The aim of this study was to analyze the complications and outcomes of treatment in a series of previously untreated patients with a primary aneurysmal bone cyst (ABC) who had been treated by percutaneous sclerosant therapy using polidocanol. Methods. Between January 2010 and December 2016, 56 patients were treated primarily with serial intralesional sclerosant injections. Their mean age was 20 years (1 to 54). The sites involved were clavicle (n = 3), humeri (n = 11), radius (n = 1), ulna (n = 3), hand (n = 2), pelvis (n = 12), femur (n = 7), tibia (n = 13), fibula (n = 3), and foot (n = 1). After histopathological confirmation of the diagnosis, 3% polidocanol (hydroxypolyaethoxydodecan) was injected into the lesion under image intensifier guidance. Patients were evaluated clinically and radiologically every six to eight weeks. In the absence of clinical and/or radiological response, a repeat sclerosant injection was given after eight to 12 weeks and repeated at similar intervals if necessary. Results. There were no complications of treatment. One patient was lost to follow-up. Overall, 46/55 (84%) of lesions healed after one or more injections of polidocanol: 24/55 (44%) patients healed with a single injection, and 43/55 (78%) within two injections. Of these 46, four (9%) patients developed local recurrence, two of whom healed with a repeat sclerosant injection. Thus, 44/55 (80%) patients of primary ABC healed with sclerotherapy. The mean follow-up was 62 months (20 to 111). The local recurrence free survival (LRFS) with percutaneous sclerosant therapy with polidocanol was 100%, 98% (95% confidence interval (CI) 85 to 100) and 93% (95% CI 78 to 98) at two, three, and five years, respectively. Conclusion. Percutaneous sclerotherapy using polidocanol is a safe, effective, minimally invasive and inexpensive method of treating a primary ABC of the limbs or pelvis.

Bone and Soft Tissue Sarcomas represent approximately 1% of all malignant tumours. Delays in diagnosis are frequent and the average size of Sarcomas at diagnosis has averaged 10cm for many years. In 1999 guidance was produced by NICE with the aim of leading to the earlier diagnosis of common cancers – including Sarcomas. We have attempted to analyze whether this guidance has had any impact on either the size of the tumours at diagnosis or the symptom duration prior to diagnosis experienced by the patients. Data for patients referred to the Royal Orthopaedic Hospital in Birmingham between 1992 and 2007 with Bone Sarcomas (n=1592) and Soft Tissue Sarcomas (n=2004) were analysed to determine the effect of the guidance. For Bone Sarcomas the mean size of the tumours decreased from 11.2cm prior to the guidance to 10.7cm after the guidance but the change was not statistically significant (p=0.09). The mean duration of symptoms increased from 18 to 21.2 weeks (p=0.01). For Soft Tissue Sarcomas, mean size fell from 10.8cm to 9.5cm (p<0.001), however the duration of symptoms actually increased from 27.3 to 32.1 weeks (p=0.01). Statistical modelling using restricted cubic splines confirmed these trends in the data. These results show that whilst there may have been a slight improvement in the size at diagnosis of Soft Tissue Sarcomas, overall most patients still experience a long delay between the onset of symptoms and diagnosis and commencement of treatment. It is difficult to conclude that the early diagnosis guidance produced in 1999 has had a significant effect on the basis of this study. Strategies to improve awareness of the symptoms and clinical features of Bone and Soft Tissue Sarcomas are still urgently required

Aims

Most patients with advanced malignancy suffer bone metastases, which pose a significant challenge to orthopaedic services and burden to the health economy. This study aimed to assess adherence to the British Orthopaedic Oncology Society (BOOS)/British Orthopaedic Association (BOA) guidelines on patients with metastatic bone disease (MBD) in the UK.

Aims

The aim of this study was to determine the rate of indocyanine green (ICG) staining of bone and soft-tissue tumours, as well as the stability and accuracy of ICG fluorescence imaging in detecting tumour residuals during surgery for bone and soft-tissue tumours.

Aims

Due to its indolent clinical behaviour, the treatment paradigm of atypical cartilaginous tumours (ACTs) in the long bones is slowly shifting from intralesional resection (curettage) and local adjuvants, towards active surveillance through wait-and-scan follow-up. In this retrospective cohort study performed in a tertiary referral centre, we studied the natural behaviour of ACT lesions by active surveillance with MRI. Clinical symptoms were not considered in the surveillance programme.

Aims

Intra-articular (IA) tumours around the knee are treated with extra-articular (EA) resection, which is associated with poor functional outcomes. We aim to evaluate the accuracy of MRI in predicting IA involvement around the knee.

Aims

The primary objective of this study was to compare the postoperative infection rate between negative pressure wound therapy (NPWT) and conventional dressings for closed incisions following soft-tissue sarcoma (STS) surgery. Secondary objectives were to compare rates of adverse wound events and functional scores.

We have analysed the pattern of symptoms in patients presenting with synovial sarcoma to identify factors which led to long delays in diagnosis. In 35 children, the early symptoms and the results of clinical and radiological investigation were reviewed, along with the presumed diagnoses. The duration of symptoms was separated into patient delay and doctor delay. Only half of the patients had one or more of the four clinical findings suggestive of sarcoma according to the guidance of the National Institute for Clinical Excellence at the onset of symptoms. Of the 33 children for whom data were available, 16 (48.5%) presented with a painless mass and in ten (30.3%) no mass was identified. Seven (21.2%) had an unexplained joint contracture. Many had been extensively investigated unsuccessfully. The mean duration of symptoms was 98 weeks (2 to 364), the mean patient delay was 43 weeks (0 to 156) and the mean doctor delay was 50 weeks (0 to 362). The mean number of doctors seen before referral was three (1 to 6) and for 15 patients the diagnosis was obtained after unplanned excision. Tumours around the knee and elbow were associated with a longer duration of symptoms and longer doctor delay compared with those at other sites. Delays did not improve significantly over the period of our study of 21 years, and we were unable to show that delay in diagnosis led to a worse prognosis. Our findings highlight the variety of symptoms associated with synovial sarcoma and encourage greater awareness of this tumour as a potential diagnosis in childhood

Aneurysmal bone cyst is a rare tumour-like lesion which develops during growth. Our aim was to determine the efficacy of the administration of percutaneous intralesional 3% polidocanol (hydroxypolyaethoxydodecan) as sclerotherapy. Between July 1997 and December 2004 we treated 72 patients (46 males, 26 females) with a histologically-proven diagnosis of aneurysmal bone cyst, at various skeletal sites using this method. The sclerotherapy was performed under fluoroscopic guidance and general anaesthesia or sedation and local anaesthesia. The mean follow-up period was 34 months (26.5 to 80). The patients were evaluated using the Enneking system for functional assessment and all the lesions were radiologically quantified into four grades. The mean age of patients was 15.6 years (3 to 38) and the mean number of injections was three (1 to 5). Ten patients were cured by a single injection. The mean reduction in size of the lesion (radiological healing) was found to be 76.6% (61.9% to 93.2%) with a mean clinical response of 84.5% (73.4% to 100%). Recurrence was seen in two patients (2.8%) within two years of treatment and both were treated successfully by further sclerotherapy. Percutaneous sclerotherapy with polidocanol is a safe alternative to conventional surgery for the treatment of an aneurysmal bone cyst. It can be used at surgically-inaccessible sites and treatment can be performed on an out-patient basis

Aims

Urgent referral to a specialist centre for patients with a soft-tissue sarcoma (STS) has been recommended by the National Institute for Health and Care Excellence (NICE) in the UK since 2006. However, the impact of this recommendation on the prognosis for these patients remains unclear. We aimed to determine the impact of the NICE guidelines on the disease-specific survival (DSS) of patients with an STS.

Aims

Tenosynovial giant cell tumour (TGCT) is one of the most common soft-tissue tumours of the foot and ankle and can behave in a locally aggressive manner. Tumour control can be difficult, despite the various methods of treatment available. Since treatment guidelines are lacking, the aim of this study was to review the multidisciplinary management by presenting the largest series of TGCT of the foot and ankle to date from two specialized sarcoma centres.

Aims

Limb salvage for pelvic sarcomas involving the acetabulum is a major surgical challenge. There remains no consensus about what is the optimum type of reconstruction after resection of the tumour. The aim of this study was to evaluate the surgical outcomes in these patients according to the methods of periacetabular reconstruction.

Aim. To present our experience and results of percutaneus sclerotherapy of aneurysmal bone cysts (ABC). Method. All patients from January 2007 to September 2009, where radiology and cytology were consistent with ABC (n=20), were treated with repeated injections of 30 mg/ml polidocanol. The mean age was 16 (5-27) years. There were 13 lesions in the long bones, 2 in the pelvic bones, 2 in the sacrum, 2 in the foot, and 1 in a finger. The sclerotherapy was performed under fluoroscopic or CT guidance and under local or general anesthesia. Each injection consisted of 2 mg polidocanol per kg body weight. Three injections with an interval of 4 weeks were most commonly scheduled. Radiological assessment was performed regularly after the last injection. Injections were continued if the lesion had not healed. Results. All patients were successfully treated after mean 3.5 (1-11) injections. The patient with an ABC and pathologic fracture in a finger needed 11 injections. No patient was operated. The only side effect was in 2 patients who experienced local inflammatory reaction during 2 weeks after the sclerotherapy. Conclusion. Our results are in concordance with published data from India, showing that percutaneus sclerotherapy with polidocanol is a safe alternative to surgery for the treatment of ABC. It is especially valuable in the pelvis and sacrum where surgery is associated with considerable morbidity

Introduction. Tissue diagnosis is essential to direct the definitive management of a suspected soft tissue or bone sarcoma tissue. Knowledge of both the diagnostic yield and accuracy of core needle biopsies is therefore important to give the investigating team information on the likelihood of their initial investigations achieving a diagnosis. Methods. This is a retrospective study of patients referred to a specialist orthopaedic centre for investigation of a suspected soft tissue or bone sarcoma. Details of all core needle biopsies performed in a 13-month period were obtained from the hospital database. We defined a diagnostic biopsy as either a specific tissue diagnosis or a biopsy that decided the definitive management of the patient, specifically if malignancy was excluded and no further intervention was required, to calculate the diagnostic yield. Diagnostic accuracy was established by comparing histological diagnosis at biopsy to that at final excision. Results. The overall diagnostic yield of the biopsies performed was 85% (125 of 148 biopsies) and the diagnostic accuracy was 93% (77 of 83). The diagnostic yield of soft tissue lesions was 93% (79 of 85) and accuracy 98%. For bone lesions the diagnostic yield was 73% (46 of 73) and accuracy was 85%. Discussion. Knowing the diagnostic yield and accuracy of biopsies performed allows the investigating team to give patients and colleagues a figure detailing the likely success of a soft tissue or bone biopsy in being diagnostic. In addition this data provides the investigating team with information on specific biopsy types that are less likely to be diagnostic, such as bone lesions requiring CT guidance. These may benefit from another biopsy method to avoid delay in diagnosis and facilitate timely management

Introduction. General Practitioners will be confronted with a sarcoma rarely in their working lives. Most will never see a bone sarcoma although most will see at least one soft tissue sarcoma. Guidelines designed to lead to earlier diagnosis of the most common cancers were introduced by NICE in 2000 and were updated in 2005, containing basic guidance on the earlier diagnosis of bone and soft tissue tumours. Referral criteria include: masses greater than 5cm in diameter, masses deep to fascia, masses which are fixed or immobile, masses which are painful, those which are increasing in size and recurrence after previous excision. Methods. We examined 350 General Practitioner referrals over the past 3 years to our service and examined the correlation between the above criteria and the likelihood of malignancy. Results. 33.3% of all tumours were malignant. The likelihood of a painful tumour proving malignant was 33.1% and therefore pain was not a valid predictor of malignancy (p = 0.86). Effectively, pain did not confer a relative risk. The likelihood of a growing tumour proving malignant was 38.5% and therefore increasing size is a predictor of malignancy (p = 0.03). Increasing size conferred a relative risk of 1.42 on a growing tumour. 67% of GP's said that they felt uncertain in determining whether a lesion was deep to fascia. Discussion. Whilst the introduction of the NICE guidelines has provided a clearer indication for referral than existed previously, we did not find all the referral criteria to be of particular value. In particular, pain did not correlate strongly with the likelihood of a tumour proving malignant. Specifically, GPs need further education to improve their working knowledge of this rare disease

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.

We report the results of a prospective study of 23 patients in which interstitial laser photocoagulation (ILP) was used to treat an osteoid osteoma. ILP is a technique in which tumour tissue is destroyed by direct heating using low-power laser light energy delivered by thin (400 μm) optical fibres which are introduced percutaneously into the tumour under image guidance. Pain was evaluated before operation and at the latest follow-up using a visual analogue scale with 0 denoting no pain and 10 the worst pain imaginable. The mean follow-up was for 15 months. The results showed that the mean pain score decreased from 7.5 before operation to 0.95 at the latest follow-up. Fourteen patients had no pain and eight had minor discomfort, not requiring analgesia. One patient required a second procedure because placement of the fibre had not been accurate enough and one developed recurrent symptoms eight months after treatment. All patients were satisfied with the operation because of the rapid resolution of pain, the minimally invasive nature of the procedure, and the fact that there was no postoperative restriction of activity

Aims

For paediatric and adolescent patients with growth potential, preservation of the physiological joint by transepiphyseal resection (TER) of the femur confers definite advantages over arthroplasty procedures. We hypothesized that the extent of the tumour and changes in its extent after neoadjuvant chemotherapy are essential factors in the selection of this procedure, and can be assessed with MRI. The oncological and functional outcomes of the procedure were reviewed to confirm its safety and efficacy.

Aims

The early mortality in patients with hip fractures from bony metastases is unknown. The objectives of this study were to quantify 30- and 90-day mortality in patients with proximal femoral metastases, and to create a mortality prediction tool based on biomarkers associated with early death.
