Surgical site infection (SSI) after soft-tissue sarcoma (STS) resection is a serious complication. The purpose of this retrospective study was to investigate the risk factors for SSI after STS resection, and to develop a nomogram that allows patient-specific risk assessment. A total of 547 patients with STS who underwent tumour resection between 2005 and 2021 were divided into a development cohort and a validation cohort. In the development cohort of 402 patients, the least absolute shrinkage and selection operator (LASSO) regression model was used to screen possible risk factors of SSI. To select risk factors and construct the prediction nomogram, multivariate logistic regression was used. The predictive power of the nomogram was evaluated by receiver operating curve (ROC) analysis in the validation cohort of 145 patients.Aims
Methods
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. We reviewed 61 patients (37 male, 24 female; mean age 42 years (SD 19)) who had undergone resection of the scapula. The most common resection was type 2 (n = 34) according to the Tikhoff-Linberg classification, or type S1A (n = 35) on the Enneking classification.Aims
Methods
Clear cell sarcoma (CCS) of soft-tissue is a rare melanocytic subtype of mesenchymal malignancy. The aim of this study was to investigate the clinical and therapeutic factors associated with increased survival, stratified by clinical stage, in order to determine the optimal treatment. The study was a retrospective analysis involving 117 patients with histologically confirmed CCS, between July 2016 and November 2017, who were enrolled in the Bone and Soft Tissue Tumour Registry in Japan.Aims
Methods
The risk of postoperative complications after resection of soft-tissue sarcoma in the medial thigh is higher than in other locations. This study investigated whether a vessel sealing system (VSS) could help reduce the risk of postoperative complications after wide resection of soft-tissue sarcoma in the medial thigh. Of 285 patients who underwent wide resection for soft-tissue sarcoma between 2014 and 2021 at our institution, 78 patients with tumours in the medial thigh were extracted from our database. Information on clinicopathological characteristics, preoperative treatment, surgical treatment (use of VSS, blood loss volume, operating time), and postoperative course (complications, postoperative haemoglobin changes, total drainage volume, and drainage and hospitalization durations) were obtained from medical records. We statistically compared clinical outcomes between patients whose surgery did or did not use VSS (VSS and non-VSS groups, respectively).Aims

The aim of this study was to determine the prevalence and impact of tourniquet use in patients undergoing limb salvage surgery with endoprosthetic reconstruction for a tumour around the knee. We retrieved data from the Prophylactic Antibiotic Regimens in Tumor Surgery (PARITY) trial; specifically, differences in baseline characteristics, surgical details, and postoperative functional outcomes between patients who had undergone surgery under tourniquet and those who had not. A linear regression model was created to evaluate the impact of tourniquet use on postoperative Toronto Extremity Salvage Scores (TESSs) while controlling for confounding variables. A negative-binomial regression model was constructed to explore predictors of postoperative length of stay (LOS).Aims

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 aim of this study is to evaluate the clinical results of operative intervention for femoral metastases which were selected based on expected survival and to discuss appropriate surgical strategies. From 2002 to 2017, 148 consecutive patients undergoing surgery for femoral metastasis were included in this study. Prognostic risk assessments were performed according to the Katagiri and revised Katagiri scoring system. In general, the low-risk group underwent resection and reconstruction with endoprosthetic replacement (EPR), while the high-risk group underwent internal fixation (IF) and radiation therapy. For the intermediate-risk group, the operative choice depended on the patient’s condition, degree of bone destruction, and radio-sensitivity. Overall survival, local failure, walking ability, and systemic complications were evaluated.Aims
Methods
We analyzed the long-term outcomes of patients observed over ten years after resection en bloc and reconstruction with extracorporeal irradiated autografts This retrospective study included 27 patients who underwent resection en bloc and reimplantation of an extracorporeal irradiated autograft. The mean patient age and follow-up period were 31.7 years (9 to 59) and 16.6 years (10.3 to 24.3), respectively. The most common diagnosis was osteosarcoma (n = 10), followed by chondrosarcoma (n = 6). The femur (n = 13) was the most frequently involved site, followed by the tibia (n = 7). There were inlay grafts in five patients, intercalary grafts in 15 patients, and osteoarticular grafts in seven patients. Functional outcome was evaluated with the Musculoskeletal Tumor Society (MSTS) scoring system.Aims
Patients and Methods
The aims of this study were to analyse the long-term outcome
of vascularised fibular graft (VFG) reconstruction after tumour
resection and to evaluate the usefulness of the method. We retrospectively reviewed 49 patients who had undergone resection
of a sarcoma and reconstruction using a VFG between 1988 and 2015.
Their mean follow-up was 98 months (5 to 317). Reconstruction was
with an osteochondral graft (n = 13), intercalary graft (n = 12),
inlay graft (n = 4), or resection arthrodesis (n = 20). We analysed
the oncological and functional outcome, and the rate of bony union
and complications.Aims
Patients and Methods
In this cross sectional study, the impact and the efficacy of a surveillance programme for sarcomas of the extremities was analysed. All patients who had treatment with curative intent for a high-grade sarcoma and were diagnosed before 2014 were included and followed for a minimum of two years.Objectives
Methods
Our objective was to predict the knee extension strength and post-operative function in quadriceps resection for soft-tissue sarcoma of the thigh. A total of 18 patients (14 men, four women) underwent total or partial quadriceps resection for soft-tissue sarcoma of the thigh between 2002 and 2014. The number of resected quadriceps was surveyed, knee extension strength was measured with the Biodex isokinetic dynamometer system (affected side/unaffected side) and relationships between these were examined. The Musculoskeletal Tumor Society (MSTS) score, Toronto Extremity Salvage Score (TESS), European Quality of Life-5 Dimensions (EQ-5D) score and the Short Form 8 were used to evaluate post-operative function and examine correlations with extension strength. The cutoff value for extension strength to expect good post-operative function was also calculated using a receiver operating characteristic (ROC) curve and Fisher’s exact test.Objectives

Patients who have limb amputation for musculoskeletal
tumours are a rare group of cancer survivors. This was a prospective
cross-sectional survey of patients from five specialist centres

Atypical cartilaginous tumours are usually treated
by curettage. The purpose of this study was to show that radiofrequency
ablation was an effective alternative treatment. We enrolled 20 patients (two male, 18 female, mean age 56 years
(36 to 72) in a proof-of-principle study. After inclusion, biopsy
and radiofrequency ablation were performed, followed three months
later by curettage and adjuvant phenolisation. The primary endpoint
was the proportional necrosis in the retrieved material. Secondary endpoints
were correlation with the findings on gadolinium enhanced MRI, functional
outcome and complications. Our results show that 95% to 100% necrosis was obtained in 14
of the 20 patients. MRI had a 91% sensitivity and 67% specificity
for detecting residual tumour after curettage. The mean functional
outcome (MSTS) score six weeks after radiofrequency ablation was
27.1 (23 to 30) compared with 18.1 (12 to 25) after curettage (p
<
0.001). No complications occurred after ablation, while two
patients developed a pathological fracture after curettage. We have shown that radiofrequency ablation is capable of completely
eradicating cartilaginous tumour cells in selective cases. MRI has
a 91% sensitivity for detecting any residual tumour. Radiofrequency
ablation can be performed on an outpatient basis allowing a rapid
return to normal activities. If it can be made more effective, it
has the potential to provide better local control, while improving
functional outcome. Cite this article:
We evaluated the clinical results and complications
after extra-articular resection of the distal femur and/or proximal
tibia and reconstruction with a tumour endoprosthesis (MUTARS) in
59 patients (mean age 33 years (11 to 74)) with malignant bone or
soft-tissue tumours. According to a Kaplan–Meier analysis, limb
survival was 76% (95% confidence interval (CI) 64.1 to 88.5) after
a mean follow-up of 4.7 years (one month to 17 years). Peri-prosthetic infection
was the most common indication for subsequent amputation (eight
patients). Survival of the prosthesis without revision was 48% (95%
CI 34.8 to 62.0) at two years and 25% (95% CI 11.1 to 39.9) at five years
post-operatively. Failure of the prosthesis was due to deep infection
in 22 patients (37%), aseptic loosening in ten patients (17%), and
peri-prosthetic fracture in six patients (10%). Wear of the bearings
made a minor revision necessary in 12 patients (20%). The mean Musculoskeletal
Tumor Society score was 23 (10 to 29). An extensor lag >
10° was
noted in ten patients (17%). These results suggest that limb salvage after extra-articular
resection with a tumour prosthesis can achieve good functional results
in most patients, although the rates of complications and subsequent
amputation are higher than in patients treated with intra-articular
resection. Cite this article:
The aims of this study were to evaluate the incidence
of local argyria in patients with silver-coated megaprostheses and
to identify a possible association between argyria and elevated
levels of silver both locally and in the blood. Between 2004 and
2011, 32 megaprostheses with silver coatings were implanted in 20
female and 12 male patients following revision arthroplasty for
infection or resection of a malignant tumour, and the levels of
silver locally in drains and seromas and in the blood were determined.
The mean age of the patients was 46 years (10 to 81); one patient
died in the immediate post-operative period and was excluded. Seven patients (23%) developed local argyria after a median of
25.7 months (interquartile range 2 to 44.5). Patients with and without
local argyria had comparable levels of silver in the blood and aspiration
fluids. The length of the implant did not influence the development
of local argyria. Patients with clinical evidence of local argyria
had no neurological symptoms and no evidence of renal or hepatic
failure. Thus, we conclude that the short-term surveillance of blood
silver levels in these patients is not required. Cite this article:
It is important to be able to identify patients
with an increased risk of venous thromboembolism (VTE) in order
to minimise the risk of an event. We investigated the incidence
and risk factors for post-operative VTE in 168 consecutive patients
with a malignancy of the lower limb. The period of study included
ten months before and 12 months after the introduction of chemical
thromboprophylaxis. All data about the potential risk factors were identified
and classified into three groups (patient-, surgery- and tumour-related).
The outcome measure was a thromboembolic event within 90 days of
surgery. Of the 168 patients, eight (4.8%) had a confirmed symptomatic
deep-vein thrombosis and one (0.6%) a fatal pulmonary embolism.
Of the 28 variables tested, age >
60 years, higher American Society
of Anesthesiologists grade and metastatic tumour were independent
risk factors for VTE. The overall rate of symptomatic VTE was not significantly
different between patients who received chemical thromboprophylaxis
and those who did not. Knowledge of these risk factors may be of
value in improving the surgical outcome of patients with a malignancy
of the lower limb. Cite this article:
We have reviewed the data from our regional Bone Tumour Registry on patients with osteosarcoma diagnosed between 1933 and 2004 in order to investigate the relationship between survival and changes in treatment. There were 184 patients with non-metastatic appendicular osteosarcoma diagnosed at the age of 18 or under. Survival was calculated using Kaplan-Meier curves, and multivariate analysis was performed using the Cox regression proportional hazards model. The five-year survival improved from 21% between 1933 and 1959, to 62% between 1990 and 1999. During this time, a multi-disciplinary organisation was gradually developed to manage treatment. The most significant variable affecting outcome was the date of diagnosis, with trends in improved survival mirroring the introduction of increasingly effective chemotherapy. Our experience suggests that the guidelines of the National Institute for Clinical Excellence on the minimum throughput of centres for treatment should be enforced flexibly in those that can demonstrate that their historical and contemporary results are comparable to those published nationally and internationally.
Despite local treatment with systemic chemotherapy in Ewing’s sarcoma family tumours (ESFT), patients with detectable metastases at presentation have a markedly worse prognosis than those with apparently localised disease. We investigated the clinical, pathological and laboratory differences in 888 patients with ESFT, 702 with localised disease and 186 with overt metastases at presentation, seen at our institution between 1983 and 2006. Multivariate analyses showed that location in the pelvis, a high level of serum lactic dehydrogenase, the presence of fever and a short interval between the onset of symptoms and diagnosis were indicative of metastatic disease. The rate of overt metastases at presentation was 10% without these four risk factors, 22.7% with one, 31.4% with two, and 50% for those with three or four factors. We concluded that in ESFT the site, the serum level of lactic dehydrogenase, fever, and the interval between the onset of symptoms and diagnosis are indicators of tumours having a particularly aggressive metastatic behaviour.
We evaluated the construct validity of the Musculoskeletal Tumour Society rating scale (Enneking score) as a functional measure for patients with sarcoma involving the upper limb. We compared the Enneking score by examining the correlation between two patient-derived outcome measures, the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire and the Medical Outcomes Study Short Form-36 (SF-36) as indicators of functional status in 40 patients with malignant or aggressive benign
