Aims. The modified Glasgow Prognostic Score (mGPS) uses preoperative CRP and albumin to calculate a score from 0 to 2 (2 being associated with poor outcomes). mGPS is validated in multiple carcinomas. To date, its use in soft-tissue sarcoma (STS) is limited, with only small cohorts reporting that increased mGPS scores correlates with decreased survival in STS patients. Methods. This retrospective multicentre cohort study identified 493 STS patients using clinical databases from six collaborating hospitals in three countries. Centres performed a retrospective data collection for patient demographics, preoperative blood results (CRP and albumin levels and neutrophil, leucocyte, and platelets counts), and oncological outcomes (disease-free survival, local, or metastatic recurrence) with a minimum of two years' follow-up. Results. We found that increased mGPS, tumour size, grade, neutrophil/lymphocyte ratio, and disease recurrence were associated with reduced survival. Importantly, mGPS was the best at stratifying prognosis and could be used in conjunction with tumour grade to sub-stratify patient survival. Conclusion. This study demonstrated that prognosis of localized STS strongly correlates with mGPS, as an increasing score is associated with a poorer outcome. We note that 203 patients (41%) with an STS have evidence of systemic inflammation. We recommend the mGPS and other biochemical blood indicators be introduced into the routine diagnostic assessment in STS patients to stratify patient prognosis. Its use will support clinical decision-making, especially when morbid treatment options such as amputation are being considered. Cite this article: Bone Joint J 2022;104-B(1):168–176

The aim of this study was to determine whether the level of circulating C-reactive protein (CRP) before treatment predicted overall disease-specific survival and local tumour control in patients with a sarcoma of bone. We retrospectively reviewed 318 patients who presented with a primary sarcoma of bone between 2003 and 2010. Those who presented with metastases and/or local recurrence were excluded. Elevated CRP levels were seen in 84 patients before treatment; these patients had a poorer disease-specific survival (57% at five years) than patients with a normal CRP (79% at five years) (p < 0.0001). They were also less likely to be free of recurrence (71% at five years) than patients with a normal CRP (79% at five years) (p = 0.04). Multivariate analysis showed the pre-operative CRP level to be an independent predictor of survival and local control. Patients with a Ewing’s sarcoma or chondrosarcoma who had an elevated CRP before their treatment started had a significantly poorer disease-specific survival than patients with a normal CRP (p = 0.02 and p < 0.0001, respectively). Patients with a conventional osteosarcoma and a raised CRP were at an increased risk of poorer local control. We recommend that CRP levels are measured routinely in patients with a suspected sarcoma of bone as a further prognostic indicator of survival. Cite this article: Bone Joint J 2013;95-B:411–18

Aim. Preoperative serum CRP has been identified as an independent predictor in various malignancies. For osteosarcoma, however, the value of serological markers is unreliable. Aim of this study was to evaluate the prognostic power of preoperative CRP in patients with osteosarcoma. Method. Out of our prospective database, 87 patients with osteosarcoma (43 female, 44 male with an average age of 20.4 years) have been identified with complete documentation of peri-operative CRP-levels, a minimum two year follow-up and after exclusion of concomitant infection, smoking-history or cardio-vascular disease. Pre-operative CRP before tumour resection was correlated with clinical and pathological factors, overall survival and infection rates in an uni- and multi-variate statistical model with and without landmark analysis. Results. Mean pre-operative serum CRP was 0.73mg/dL (range 0.0 to 8.5) and significantly correlated with overall survival, age at time of operation and histological subtype, but not with sex, tumour grading, response to chemotherapy, recurrent disease or post-operative infection in uni-variate analysis. Patients with CRP <1mg/dL had a five year overall survival of 70% compared to 43% for patients with CRP >1mg/dL (p=0.023). In multi-variate analysis both age and pre-operative CRP had an independent significant influence on overall survival. The hazard ratio for patients with elevated levels of CRP was 1.252. In a subgroup analysis of 60 patients with endoprosthetic replacement, pre-operative CRP was no significant predictor for deep prosthetic infection and infection was no significant predictor for overall survival with and without landmark-analysis though patients with infection showed lower levels of CRP. However, this difference was not significant. Conclusion. Pre-operative serum CRP is an independent prognostic factor for overall survival of patients with osteosarcoma, but not for infection. Its role in predicting response to established chemotherapies, as well as the controversially discussed impact of infection on survival will remain subject of multi-centre investigations

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.

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. Results. There were 541 patients included in the analysis of whom 221 had osteosarcoma, 167 chondrosarcoma, 87 Ewing's, and 66 other bone tumours. 340 were adults, 103 children (under 14) and 98 TYA. The most frequently abnormal blood test was a low haemoglobin (⋋13) in 56%, raised alkaline phosphatase in 40%, and raised ESR and CRP in 32%. Patients with metastases at diagnosis tended to have higher levels of ESR (p⋋0.0001) but there was no other significant difference overall. Older patients tended to have a greater number of abnormal results apart from the CRP which was highest in the TYA group. No single blood test was related to prognosis. Conclusion. Abnormal blood tests are common in patients at the time of diagnosis of bone tumours. None are either particularly diagnostic or prognostic

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

Radiotherapy is a well-known local treatment for spinal metastases. However, in the presence of postoperative systemic therapy, the efficacy of radiotherapy on local control (LC) and overall survival (OS) in patients with spinal metastases remains unknown. This study aimed to evaluate the clinical outcomes of post-surgical radiotherapy for spinal metastatic non-small-cell lung cancer (NSCLC) patients, and to identify factors correlated with LC and OS.

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.

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.

The aim of this study was to determine whether the high-sensitivity modified Glasgow prognostic score (Hs-mGPS) could predict the disease-specific survival and oncological outcome in adult patients with non-metastatic soft-tissue sarcoma before treatment. A total of 139 patients treated between 2001 and 2012 were retrospectively reviewed. The Hs-mGPS varied between 0 and 2. Patients with a score of 2 had a poorer disease-specific survival than patients with a score of 0 (p < 0.001). The estimated five-year rate of disease-specific survival for those with a score of 2 was 0%, compared with 85.4% (95% CI 77.3 to 93.5) for those with a score of 0. Those with a score of 2 also had a poorer disease-specific survival than those with a score of 1 (75.3%, 95% CI 55.8 to 94.8; p < 0.001). Patients with a score of 2 also had a poorer event-free rate than those with a score of 0 (p < 0.001). Those with a score of 2 also had a poorer event-free survival than did those with a score of 1 (p = 0.03). A multivariate analysis showed that the Hs-mGPS remained an independent predictor of survival and recurrence. The Hs-mGPS could be a useful prognostic marker in patients with a soft-tissue sarcoma.
