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. 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.Aims
Methods
Malignancy and surgery are risk factors for venous thromboembolism (VTE). We undertook a systematic review of the literature concerning the prophylactic management of VTE in orthopaedic oncology patients. MEDLINE (PubMed), EMBASE (Ovid), Cochrane, and CINAHL databases were searched focusing on VTE, deep vein thrombosis (DVT), pulmonary embolism (PE), bleeding, or wound complication rates.Aims
Methods
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 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
Methods
The aim of this study was to determine the risk of local recurrence and survival in patients with osteosarcoma based on the proximity of the tumour to the major vessels. A total of 226 patients with high-grade non-metastatic osteosarcoma in the limbs were investigated. Median age at diagnosis was 15 years (4 to 67) with the ratio of male to female patients being 1.5:1. The most common site of the tumour was the femur (n = 103) followed by tibia (n = 66). The vascular proximity was categorized based on the preoperative MRI after neoadjuvant chemotherapy into four types: type 1 > 5 mm; type 2 ≤ 5 mm, > 0 mm; type 3 attached; type 4 surrounded.Aims

Patients and Methods
The purpose of this study was to determine if clinical and radiological
surveillance of cartilage tumours with low biological activity is
appropriate. A total of 98 patients with an intramedullary cartilage neoplasm
in a long bone met our inclusion criteria and were included in the
study. These patients had undergone a total of 384 scans. Patients
with radiological follow-up of more than three years (46 patients)
were divided into two groups: an active group (11 patients) and
a latent group (35 patients).Aims
Patients and Methods
CT guided percutaneous radiofrequency thermo coagulation is the treatment of choice for osteoid osteomas. Good results with a low complication rate have been shown for spinal lesions. When lesions are within close proximity to neurological structures or if patients have radicular symptoms surgery rather than radiofrequency ablation has been advocated. We present our experience of radiofrequency ablation of spinal osteoid osteomas which are less than 5mm from neurological structures, including those causing radicular symptoms. Data was collected prospectively on all patients with a spinal osteoid osteoma within 5mm of nerve roots or the spinal cord as measured on CT scanning. There were nine patients, five female and four males. Four were located in the thoracic spine, three in the lumbar spine and two in the cervical spine. The mean distance to the nearest neurological structure was 3mm. Radicular symptoms were present in two patients. The mean number of probe positions used was two. Lesions were heated to 90 degrees for 5 minutes for each probe position. There were two cases of recurrence, both treated successfully with one further procedure each. There were no cases of neurological injury. The two patients with radicular symptoms had full resolution of their symptoms. At a mean follow up of 2 years following treatment all patients are asymptomatic.Introduction
Methods
To evaluate the rise in impedance during percutaneous radiofrequency thermo coagulation (PRFTC) of osteoid osteomas as a predictor of local recurrence. A prospective study of 23 patients (24 PRFTC procedures) with minimum of 2.25-year follow-up (average 3.3 years). Average age 19.6 years (range 4–44), sex ratio 15□:□8 (male□:□female), 16 non-diaphyseal, 7 diaphyseal.Objective
Design and Patients
Enchondromas located in the phalangeal bones may be more cellular than non-digital locations necessitating clinical and radiological correlation to determine diagnosis. Atypical enchondromas have increased cellularity and atypia relative to simple enchondromas but no evidence of permeation. Chondrosarcomas of the phalanges are thought to have a more indolent course than chondrosarcomas in other locations. The aim of the study was to determine the outcome of atypical enchondromas and grade 1 chondrosarcomas of the phalanges treated surgically. Data was collected prospectively on patients with a cartilage lesion of the phalanges. Typical enchondromas, grade 2 or 3 chondrosarcomas and patients with Ollier's disease were excluded.Introduction
Methods
Periarticular metastasis may be treated with endoprosthetic reconstruction. The extensive surgery required may not, however, be appropriate for all patients. Our aim was to establish if the outcome of locking plate fixation in selected patients with periarticular metastases. Prospective data collection was performed. Twenty one patients underwent surgery for periarticular metastatic tumours. The median duration of follow-up for surviving patients was one year. There have been no cases of implant failure and no requirement for revision surgery. Pain relief was excellent or good in the majority of patients. Patients who had sustained a fracture prior to fixation had restoration of their WHO performance status. All patients had a dramatic improvement in their MSTS scores. The median pre-operative score was 15% (0%-37%) improving to a median score of 80% (75% -96%) post operatively. Locking plates provide reliable fixation and excellent functional restoration in selected patients suffering from periarticular metastatic bone disease.

Radiofrequency ablation can be safely performed to treat osteoid osteomas located within 5mm of neurological structures and has a low rate of recurrence.
