Aims. Although chondrosarcomas (CSs) display true malignant features, including local recurrence (LR) and metastases, their behaviour in the hands and feet is thought to differ from that in other parts of the axial and appendicular skeleton by having a lower metastatic potential. The purpose of this study was to investigate the disease-specific and surgical factors that affect the local and systemic prognosis of CS of the hands and feet. Methods. A multicentre retrospective study was carried out at two tertiary sarcoma centres. A database search identified all patients with a CS treated between January 1995 and January 2018. There were 810 CSs of which 76 (9.4%) were located in the fingers, toes, metacarpals, and metatarsal bones. Results. The median age of the study population was 55 years (36 to 68) with a median follow-up of 52 months (22 to 87) months. Overall, 70% of the tumours were in the hand (n = 54) and 30% in the foot (n = 22). Predictors for LR were margin (p = 0.011), anatomical location (p = 0.017), and method of surgical management (p = 0.003). Anatomical location (p = 0.026), histological grade between 1 and 3 (p = 0.004) or 2 and 3 (p = 0.016), and surgical management (p = 0.001) were significant factors for LR-free survival. Disease-specific survival was affected by histological grade (p < 0.001), but not by LR (p = 0.397). Conclusion. Intralesional curettage of a low-grade CS is associated with an increased risk of LR, but LR does not affect disease-specific survival. Therefore, for low-grade CSs of the hands and feet, surgical management should aim to preserve function. In grade 2 CS, our study did not show any decreased disease-specific survival after recurrence; however, we suggest a more aggressive surgical approach to these tumours to prevent local recurrence, especially in the metacarpal and metatarsal bones. In high-grade tumours, the incidence of progressive disease is high and, therefore, the treatment of the primary tumour should be aggressive where possible, and patients observed closely for the development of metastatic disease.

Giant cell tumours (GCTs) of the small bones of the hands and feet are rare. Small case series have been published but there is no consensus about ideal treatment. We performed a systematic review, initially screening 775 titles, and included 12 papers comprising 91 patients with GCT of the small bones of the hands and feet. The rate of recurrence across these publications was found to be 72% (18 of 25) in those treated with isolated curettage, 13% (2 of 15) in those treated with curettage plus adjuvants, 15% (6 of 41) in those treated by resection and 10% (1 of 10) in those treated by amputation. We then retrospectively analysed 30 patients treated for GCT of the small bones of the hands and feet between 1987 and 2010 in five specialised centres. The primary treatment was curettage in six, curettage with adjuvants (phenol or liquid nitrogen with or without polymethylmethacrylate (PMMA)) in 18 and resection in six. We evaluated the rate of complications and recurrence as well as the factors that influenced their functional outcome. At a mean follow-up of 7.9 years (2 to 26) the rate of recurrence was 50% (n = 3) in those patients treated with isolated curettage, 22% (n = 4) in those treated with curettage plus adjuvants and 17% (n = 1) in those treated with resection (p = 0.404). The only complication was pain in one patient, which resolved after surgical removal of remnants of PMMA. We could not identify any individual factors associated with a higher rate of complications or recurrence. The mean post-operative Musculoskeletal Tumor Society scores were slightly higher after intra-lesional treatment including isolated curettage and curettage plus adjuvants (29 (20 to 30)) compared with resection (25 (15 to 30)) (p = 0.091). Repeated curettage with adjuvants eventually resulted in the cure for all patients and is therefore a reasonable treatment for both primary and recurrent GCT of the small bones of the hands and feet.

We have investigated the oncological outcome of 63 patients with soft-tissue sarcomas of the hand managed at three major centres in the United Kingdom. There were 44 males and 19 females with a mean age of 45 years (11 to 92). The three most common diagnoses were synovial sarcoma, clear cell sarcoma and epithelioid sarcoma. Local excision was carried out in 45 patients (71%) and amputation in 18 (29%). All those treated by amputation had a wide margin of excision but this was only achieved in 58% of those treated by local excision. The risk of local recurrence was 6% in those treated by amputation compared with 42% for those who underwent attempted limb salvage. An inadequate margin of excision resulted in a 12 times greater risk of local recurrence when compared with those in whom a wide margin of excision had been achieved. We were unable to demonstrate any role for radiotherapy in decreasing the risk of local recurrence when there was an inadequate margin of excision. Patients with an inadequate margin of excision had a much higher risk of both local recurrence and metastasis than those with wide margins. The overall survival rate at five years was 87% and was related to the grade and size of the tumour and to the surgical margin. We have shown that a clear margin of excision is essential to achieve local control of a soft-tissue sarcoma in the hand and that failure to achieve this results in a high risk of both local recurrence and metastastic disease

Aims. The aim of this study was to evaluate the surgical management and outcome of patients with an acral soft-tissue sarcoma of the hand or foot. Patients and Methods. We identified 63 patients with an acral soft-tissue sarcoma who presented to our tertiary referral sarcoma service between 2000 and 2016. There were 35 men and 28 women with a mean age of 49 years (. sd. 21). Of the 63 sarcomas, 27 were in the hands and 36 in the feet. The commonest subtypes were epithelioid sarcoma in the hand (n = 8) and synovial sarcoma in the foot (n = 11). Results. In 41 patients (65%), the tumour measured less than 5 cm in its largest dimension (median size 3 cm (٢ to ٦)); 27 patients (43%) were diagnosed after inadvertent excision prior to their referral to the specialist sarcoma unit. After biopsy and staging, primary surgical intervention at the sarcoma unit was excision and limb salvage in 43 (68%), partial (digit or ray) amputation in 14 (22%), and more proximal amputation in six (10%). At final follow up, local recurrence had been treated by one partial amputation and six amputations, resulting in a partial amputation rate of 24% and a proximal amputation rate of 19%. The five-year survival rate was 82%. Patients who underwent inadvertent excision showed no statistically significant difference in survival or local recurrence, but were more likely to undergo amputation (p = 0.008). Large tumour size (> 5 cm) was associated with lower survival (p = 0.04) and a higher risk of local recurrence (p = ٠.٠٠٩). Conclusion. Most acral soft-tissue sarcomas measure less than 5 cm at presentation, indicating that while size can be a useful prognostic factor, it should not be used as a diagnostic threshold for referral. Increased tumour size is associated with a higher rate of local recurrence and reduced survival. Sarcoma excision with limb preservation does not result in an increased risk of local recurrence.

Aims. Chondrosarcoma is the second most common primary sarcoma of bone: conventional chondrosarcoma accounts for 85% of all cases. Conventional chondrosarcoma may be central or peripheral. Most studies group central and peripheral chondrosarcomas together, although there is growing evidence that their clinical behaviour and prognosis differ. The aims of this study were to analyze any differences in characteristics between central and peripheral chondrosarcomas and to investigate the incidence and role of different syndromes. Methods. Data from two international tertiary referral sarcoma centres between January 1995 and December 2018 were retrospectively reviewed. The study population consisted of 714 patients with surgically treated conventional chondrosarcoma of the pelvis and limbs. Results. In patients with Ollier’s disease and Mafucci’s syndrome, 12/20 (60%) and 2/5 (60%) of malignancies, respectively, were in the limbs, most frequently in the proximal humerus, proximal tibia, and in the hands and feet. In patients with hereditary multiple exostosis (HME), 20/29 (69.0%) of chondrosarcomas were in the pelvis and scapula, specifically in the ilium in 13/29 (44.8%) and the scapula in 3/29 (10.3%). In central chondrosarcoma, survival of patients with Ollier’s disease and non-syndromic patients was the same (p = 0.805). In peripheral chondrosarcoma, survival among HME patients was similar (p = 0.676) in patients with tumours of the pelvis and limbs. Conclusion. Both central and peripheral chondrosarcoma have specific characteristics. HME is frequently seen in patients with a peripheral chondrosarcoma, in whom tumours are commonly located in the ilium and scapula. The incidence of Ollier’s disease is uncommon in patients with a central chondrosarcoma. Disease-specific survival is equal in different subtypes after adjustment for histological grade. The local recurrence-free survival is the same for different locations and subtypes after adjustment for surgical margin. Cite this article: Bone Joint J 2021;103-B(5):984–990

Aims

The scapula is a rare site for a primary bone tumour. Only a small number of series have studied patient outcomes after treatment. Previous studies have shown a high rate of recurrence, with functional outcomes determined by the preservation of the glenohumeral joint and deltoid. The purpose of the current study was to report the outcome of patients who had undergone tumour resection that included the scapula.

Aims

This study aimed to analyze the accuracy and errors associated with 3D-printed, patient-specific resection guides (3DP-PSRGs) used for bone tumour resection.

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.

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

The aim of the LightFix Trial was to evaluate the clinical outcomes for one year after the treatment of impending and completed pathological fractures of the humerus using the IlluminOss System (IS), and to analyze the performance of this device.

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

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

This study aimed to compare the performance of survival prediction models for bone metastases of the extremities (BM-E) with pathological fractures in an Asian cohort, and investigate patient characteristics associated with survival.

Aims

Giant cell tumour of bone (GCTB) is a locally aggressive lesion that is difficult to treat as salvaging the joint can be associated with a high rate of local recurrence (LR). We evaluated the risk factors for tumour relapse after treatment of a GCTB of the limbs.

Aims

The aim of this study was to investigate the feasibility of application of a 3D-printed megaprosthesis with hemiarthroplasty design for defects of the distal humerus or proximal ulna following tumour resection.

Aims

Patients with soft-tissue sarcoma (STS) who undergo unplanned excision (UE) are reported to have worse outcomes than those who undergo planned excision (PE). However, others have reported that patients who undergo UE may have similar or improved outcomes. These discrepancies are likely to be due to differences in characteristics between the two groups of patients. The aim of the study is to compare patients who underwent UE and PE using propensity score matching, by analyzing data from the Japanese Bone and Soft Tissue Tumor (BSTT) registry.

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.

Aims

The aims of the study were to analyze differences in surgical and oncological outcomes, as well as quality of life (QoL) and function in patients with ankle sarcomas undergoing three forms of surgical treatment, minor or major limb salvage surgery (LSS), or amputation.

Aims

Our aim was to develop and validate nomograms that would predict the cumulative incidence of sarcoma-specific death (CISSD) and disease progression (CIDP) in patients with localized high-grade primary central and dedifferentiated chondrosarcoma.

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.
