Introduction

Bony tumours of foot account for approximately 3% of osseous tumours. However, literature regarding calcaneal tumours comprises individual case reports, short case series or literature reviews, with last large case series in 1973. Literature on bony tumours of the talus is limited to case reports only.

Methods

We retrospectively reviewed medical notes and imaging for all patients with calcaneal or talar tumours recorded in the Scottish Bone Tumour Registry since the 1940's. Demographics, presentation, investigation, histology, management and outcome were reviewed.

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.

Sixty eight consecutive patients underwent proximal humeral replacement with a fixed fulcrum massive endoprosthesis for tumour between 1997 and 2007. The mean age was 46 years (7-87). Ten patients were lost to follow up and 16 patients died. The 42 surviving patients were assessed using the Musculoskeletal Tumour Society (MSTS) Score and the Toronto Extremity Salvage Score (TESS). The mean MSTS score was 72.3 % and the mean TESS was 77.2 %.

Four of 42 patients received a new constrained humeral liner to reduce the risk of dislocation. This sub group of 4 patients had a mean MSTS score of 77.7 % and a mean TESS of 80.0%.

Endoprosthetic replacement for tumour of the proximal humerus using this prosthesis is a reliable operation yielding good functional results without the documented problems of unconstrained prostheses. The performance of this prosthesis is expected to improve further with the new constrained humeral liner.

Introduction

To look at the effect of width and tissue at surgical margins, together with the use of adjuvant therapy on locally recurrent disease and disease free survival.

Methods

The distance (mm) and tissue has been regularly reported for 5 years, prior to this it was reported as wide, marginal or intra-lesional. It is known from previous studies that 90% of locally recurrent disease for osteosarcoma and Ewing's occurs within 2 years from surgery. Therefore all primary bone sarcomas of the pelvis and appendicular skeleton that underwent surgery between 1/1/2005 and 1/1/2008 were entered, giving at least 2 years follow up. The pathology records were reviewed and the margins and percentage tumour necrosis were recorded. Those patients who had suffered local or distal disease relapse or died were highlighted. Analysis was undertaken by Kaplan Meier survival curves with univariate and multivariate analysis.

Introduction

Primary bone tumours of the distal radius are rare, while it remains the third commonest site for primary lesions and recurrences of Giant Cell Tumours (GCT). The functional demands on the hand make reconstruction of the wrist joint following the excision of distal radius, particularly challenging.

Methods

A single-centre retrospective study, reporting the functional and oncological outcomes of six patients (4 males, 2 females - mean age of 53 (22 to 79)) who underwent a custom-made endoprosthetic replacement of the distal radius with arthrodesis at our institution, during 1999 - 2010. Five patients were diagnosed with primary bone sarcoma of the distal radius (4 GCTs, 1 osteosarcoma) and another had a metastatic lesion from a primary renal cell carcinoma. The diagnosis was confirmed by needle biopsy in all cases.

We assessed the patients' functional outcomes using the Musculoskeletal Tumour Society scoring system (MSTS) and the Toronto Extremity Salvage Score (TESS).

Introduction

It is generally held that blood tests are not particularly helpful in establishing the diagnosis of bone tumours but may be useful in prognosis. We reviewed the results of blood tests taken at the time of diagnosis to establish the frequency of abnormalities in common blood tests and whether this was significant in staging or prognosis.

Method

Blood test results on all newly diagnosed patients with bone tumours from 2005 – 2010 were exported and abnormalities identified. This was matched to diagnosis, clinical features and prognosis.

Fibromatosis represent a highly heterogeneous group of tumours in growth pattern, location and management. Our aim was to describe the demographics of the patient population who had undergone surgical resection and to identify predictors of local recurrence. Any lesion that was infiltrating the chest or abdominal cavity was excluded. Patients were also not included if they had a plantar or palmar lesions or had received hormonal or chemotherapy.

67 men and 88 women aged from 16 to 77 with a median age of 39 were analyzed. 121 patients had no prior resective operative intervention. 34 patients had undergone an attempted resection procedure at another unit of which 30 had locally recurred. 3 were located in the abdominal wall, 5 chest wall, 15 paraspinal, 56 lower and 76 upper limb. 40 patients did not receive XRT, 18 in the post-operative period and 97 in the pre-operative period. 67 operations produced margin negative resection, 85 were positive and 3 in which the margin status was unknown. Follow-up ranged from 1 day post op to 23.3 years. 23 patients had a local recurrence. Following subsequent re-resections, the total number of patients who were alive with evidence of disease was 16.

6 pts had deceased. 149 were alive with no evidence of disease. No factors were found to be statistically significant for predicting local recurrence, including the use of radiation (0.06) and margin status (0.81). Although radiation, given either pre or post-operatively did trend towards preventing local recurrence (HR 0.40; 95% CI 0.15 to 1.06; p = 0.06).

Conclusions

The retention of critical structures whilst resecting fibromatosis continues to be an appropriate management strategy, as local recurrence rates seem to be independent of margin status. Although not statistically significant, the use of XRT did tend towards reducing local recurrence.

Introduction

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.

Methods

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

A GP may only encounter one sarcoma in their professional career. Early diagnosis and treatment will improve the outcomes of this rare and malignant disease. Guidelines designed to lead to earlier diagnosis of the most common cancers were introduced by NICE in 2000 and were updated in 2005. These advise and assist in the early referral of potential bone and soft tissue sarcoma. Prior to 2000 only ~10% of GP referrals were proven to be malignant.

Methods

In a referral region of ∼3m, we reviewed the referral patterns of suspected sarcoma by General Practitioners since 2005 in an effort to determine whether the published NICE guidelines had influenced an improvement in the diagnosis and management of malignant disease.

Earlier diagnosis is one of the key aims in achieving improved outcomes for patients with cancer. In general, the earlier a tumour is diagnosed, the easier it will be to treat and the greater the chance of cure. We have investigated how tumour size at diagnosis and duration of symptoms, both of which may act as a proxy for delay in diagnosis have varied over a 25 year period and whether there is evidence of improvement.

Data were available for 2568 patients with primary bone sarcomas and 2366 with soft tissue sarcomas. The mean size at diagnosis was 10.7 cm for bone tumours and 9.9cm for soft tissue sarcomas. The size of bone sarcomas had not changed with the passage of time but there had been a slight decrease in the size of soft tissue sarcomas (10.3 cm before 2000 vs 9.6cm after 2000, p=0.03). The duration of symptoms reported by patients varied widely with a median of 16 weeks for bone sarcomas and 26 weeks for soft tissue sarcomas. The median duration of symptoms for bone sarcomas had actually increased since 2000 (16 weeks before to 20 weeks after 2000, p⋋0.01), whilst it remained unchanged for soft tissue sarcomas. Further analysis showed that females tended to present with smaller tumours than males and that slower growing tumours (eg. liposarcoma and chondrosarcoma) tended to be larger and have a longer duration of symptoms than other tumours. 15% of patients with a soft tissue sarcoma had undergone a previous inadvertent excision – and this % has not changed over 20 years. Younger patients had smaller soft tissue soft tissue sarcomas than older patients but there was little difference for bone sarcomas.

Conclusion

This data shows there is huge room for improvement

Introduction

Our Unit has been treating large volume soft tissue sarcomas involving the sciatic nerve with epineurectomy for over a decade. The aim of this study was to quantify the functional outcome of patients who were known to have sciatic nerve involvement pre-operatively and went on to have nerve preserving surgery utilising a planned marginal excision with epineurectomy.

Methods

20 patients with soft tissue sarcomas involving the sciatic nerve were studied treated between 1997 and 2010. Nineteen underwent surgery with extended epineurectomy of the sciatic nerve and planned marginal excision. All patients underwent staging and follow up at our Sarcoma Clinic with functional assessment and TESS evaluation.

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.

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.

Aim

To present selective arterial embolization with N-2-butyl Cyanoacrylate for the palliative and/or adjuvant treatment of painful bone metastases not primarily amenable to surgery.

Material and Methods

From January 2003 to December 2009, 243 patients (148 men and 95 women; age range, 20-87 years) with painful bone metastases were treated with N-2-butyl Cyanoacrylate. Overall, 309 embolizations were performed;

56 patients had more than one embolization. Embolizations were performed in the pelvis (168 procedures), in the spine (83 procedures), in the upper limb (13 procedures), in the lower limb (38 procedures) and in the thoracic cage (21 procedures). Primary cancer included urogenital, breast, gastrointestinal, thyroid, lung, musculoskeletal, skin, nerve and unknown origin.

Renal cell carcinoma was the most commonly treated tumour. In all patients, selective embolization was performed by transfemoral catheterization.

Aim and purpose

The clinical management of osteosarcoma differs significantly from that of chondrosarcoma;

Therefore it is extremely important to diagnose these two types of bone tumour accurately. In the absence of a specific marker, differential diagnosis by histochemistry is sometimes impossible, especially between chondroblastic osteosarcoma and conventional chondrosarcoma. The aim of the study was to find an useful diagnostic marker, simple to use for distinguishes chondroblastic osteosarcoma from conventional chondrosarcoma.

Method

We analysed 165 bone sarcomas by immunohistochemical staining of tissue microarrays for expression of the galectin-1 (GAL1) lectin and by Western Blot experiments.

Aim

We investigated low grade intramedullary chondrosarcomas to see if curettage and cementation remains a strong alternative treatment to local resection.

Methods

39 patients with biopsy proven low grade chondrosarcoma treated with curettage and cementation in our clinic between 1993-2009. 32 were females and 7 were males. Mean age was 44. Mean follow up was 40.5 months. Anatomical localizations were 16 proximal humerus and 16 proximal femur, 6 distal femur and 1 proximal tibia. All patients had plain X-ray, CT scan, Tc99 bone scan and MRI before open biopsy. 28 patients had frozen intraoperative biopsy. Histological diagnosis were grade I chondrosarcoma in all our patients. Curettage followed by high speed burr and cementation with high viscosity bone cement was applied without any internal fixation. Active physiotherapy began after 2 days of the operation and full weight bearing is permitted at about 2 weeks later.

Introduction

We analyzed the results of extracorporeal radiated (ECRT) autogenous tumour bone for reconstruction of diaphyseal defects after tumour resection at our institute.

Methods

Sixteen diaphyseal bone tumours operated between March 2006 to March 2008 were reconstructed with ECRT bone after appropriate oncologic resection. These included 10 cases of Ewing's sarcoma, 5 of Osteosarcoma and 1 Adamantinoma. Nine involved femur, 5 tibia and 2 humerus. Suitable internal stabilisation (14 cases plate fixation, 2 intramedullary nails) was used after re-implanting ECRT bone. Average resection length was 18.9 cm (range, 11 to 30 cm).
