The purpose of this study was to evaluate the long-term outcome of patients with a sacral chordoma and the surgical management of locally recurrent disease. Between October 1990 and August 2013 we operated on 54 consecutive patients with a sacral chordoma. There were 34 men and 20 women with a mean age of 60 years (25 to 86). The mean maximum diameter of the tumour was 9.3 cm (3 to 20). The mean follow-up was 7.8 years (2 months to 23.4 years). The disease-specific survival was 82% at five years, 57% at ten years and 45% at 15 years. The local recurrence-free survival was 49% at five years, 37% at ten years and 20% at 15 years. Local recurrence occurred in 30 patients (56%) at a mean of 3.8 years (3 months to 13 years) post-operatively. Survival after the treatment of recurrence was 89% at two years, 56% at five years and 19% at ten years. Of nine patients who had complete resection of a recurrence, one died after 72 months and eight remain disease-free. Incomplete resection of recurrent disease resulted in a survival of 54% at two years and 36% at five years. For 12 patients with a local recurrence who were treated palliatively, survival was 81% at two years and 31% at five years. A wide margin of resection gave the best chance of long-term survival and complete resection of local recurrence the best chance of control of disease.

Aims. There is a lack of evidence about the risk factors for local recurrence of a giant cell tumour (GCT) of the sacrum treated with nerve-sparing surgery, probably because of the rarity of the disease. This study aimed to answer two questions: first, what is the rate of local recurrence of sacral GCT treated with nerve-sparing surgery and second, what are the risk factors for its local recurrence?. Methods. A total of 114 patients with a sacral GCT who underwent nerve-sparing surgery at our hospital between July 2005 and August 2017 were reviewed. The rate of local recurrence was determined, and Kaplan-Meier survival analysis carried out to evaluate the mean recurrence-free survival. Possible risks factors including demographics, tumour characteristics, adjuvant therapy, operation, and laboratory indices were analyzed using univariate analysis. Variables with p < 0.100 in the univariate analysis were further considered in a multivariate Cox regression analysis to identify the risk factors. Results. The rate of local recurrence of sacral GCT treated with nerve-sparing surgery was 28.95% (33/114). Multivariate Cox regression analysis showed that large tumour size (> 8.80 cm) (hazard ratio (HR) 3.16; 95% confidence interval (CI) 1.27 to 7.87; p = 0.014), high neutrophil-to-lymphocyte ratio (NLR) (> 2.09) (HR 3.13; 95% CI 1.28 to 7.62; p = 0.012), involvement of a sacroiliac joint (HR 3.09; 95% CI 1.06 to 9.04; p = 0.039), and massive intraoperative blood loss (> 1,550 ml) (HR 2.47; 95% CI 1.14 to 5.36; p = 0.022) were independent risk factors for local recurrence. Conclusion. Patients with a sacral GCT who undergo nerve-sparing surgery have a local recurrence rate of 29%. Large tumour size, high NLR, involvement of a sacroiliac joint, and massive intraoperative blood loss are independent risk factors. Cite this article: Bone Joint J 2020;102-B(10):1392–1398

Aims. The aim of this paper was to investigate the prognostic factors for local recurrence in patients with pathological fracture through giant cell tumours of bone (GCTB). Patients and Methods. A total of 107 patients presenting with fractures through GCTB treated at our institution (Royal Orthopaedic Hospital, Birmingham, United Kingdom) between 1995 and 2016 were retrospectively studied. Of these patients, 57 were female (53%) and 50 were male (47%).The mean age at diagnosis was 33 years (14 to 86). A univariate analysis was performed, followed by multivariate analysis to identify risk factors based on the treatment and clinical characteristics. Results. The initial surgical treatment was curettage with or without adjuvants in 55 patients (51%), en bloc resection with or without reconstruction in 45 patients (42%), and neoadjuvant denosumab, followed by resection (n = 3, 3%) or curettage (n = 4, 4%). The choice of treatment depended on tumour location, Campanacci tumour staging, intra-articular involvement, and fracture displacement. Neoadjuvant denosumab was used only in fractures through Campanacci stage 3 tumours. Local recurrence occurred in 28 patients (25%). Surgery more than six weeks after the fracture did not affect the risk of recurrence in any of the groups. In Campanacci stage 3 tumours not treated with denosumab, en bloc resection had lower local recurrences (13%), compared with curettage (39%). In tumours classified as Campanacci 2, intralesional curettage and en bloc resections had similar recurrence rates (21% and 24%, respectively). After univariate analysis, the type of surgical intervention, location, and the use of denosumab were independent factors predicting local recurrence. Further surgery was required 33% more often after intralesional curettage in comparison with resections (mean 1.59, 0 to 5 vs 1.06, 0 to 3 operations). All patients treated with denosumab followed by intralesional curettage developed local recurrence. Conclusion. In patients with pathological fractures through GCTB not treated with denosumab, en bloc resection offers lower risks of local recurrence in tumours classified as Campanacci stage 3. Curettage or resections are both similar options in terms of the risk of local recurrence for tumours classified as Campanacci stage 2. The benefits of denosumab followed by intralesional curettage in these patients still remains unclear

Aims. Iliosacral sarcoma resections have been shown to have high rates of local recurrence (LR) and poor overall survival. There is also no universal classification for the resection of pelvic sarcomas invading the sacrum. This study proposes a novel classification system and analyzes the survival and risk of recurrence, when using this system. Methods. This is a retrospective analysis of 151 patients (with median follow-up in survivors of 44 months (interquartile range 12 to 77)) who underwent hemipelvectomy with iliosacral resection at a single centre between 2007 and 2019. The proposed classification differentiates the extent of iliosacral resection and defines types S1 to S6 (S1 resection medial and parallel to the sacroiliac joint, S2 resection through the ipsilateral sacral lateral mass to the neuroforamina, S3 resection through the ipsilateral neuroforamina, S4 resection through ipsilateral the spinal canal, and S5 and S6 contralateral sacral resections). Descriptive statistics and the chi-squared test were used for categorical variables, and the Kaplan-Meier survival analysis were performed. Results. Resections were S1 in 25/151 patients (17%), S2 in 70/151 (46%), S3 in 33/151 (22%), S4 in 77/151 (11%), S5 in 4/151 (3%), and S6 in 2/151 (1%). An internal hemipelvectomy was performed in 113/151 patients (75%), and 38/151 patients (25%) had an external hemipelvectomy. The predominant types of sarcoma were high-grade osteosarcoma in 48/151 patients (32%), chondrosarcoma in 41/151 (27%), Ewing sarcoma in 33/151 (22%), pleomorphic sarcoma in 17/151 (11%), and others in 2/151 (8%). LR was found in 24/151 patients (15%) with S3, S5, with S6 resections showing the highest rate of LR (p = 0.038). Overall, 19/151 patients (16%) had evidence of metastastic disease at the time of surgery and these patients showed poorer survival when compared to patients with no metastasis. Conclusion. The proposed classification can help to report and compare different surgical and reconstructive approaches in these difficult cases who are still have a considerable risk of LR.

Pigmented villonodular synovitis (PVNS) is a rare proliferative process of the synovium which most commonly affects the knee and occurs in either a localised (LPVNS) or a diffuse form (DPVNS). The effect of different methods of surgical synovectomy and adjuvant radiotherapy on the rate of recurrence is unclear. We conducted a systematic review and identified 35 observational studies in English which reported the use of surgical synovectomy to treat PVNS of the knee. A meta-analysis included 630 patients, 137 (21.8%) of whom had a recurrence after synovectomy. For patients with DPVNS, low-quality evidence found that the rate of recurrence was reduced by both open synovectomy (odds ration (OR) = 0.47; 95% CI 0.25 to 0.90; p = 0.024) and combined open and arthroscopic synovectomy (OR = 0.19, 95% CI = 0.06 to 0.58; p = 0.003) compared with arthroscopic surgery. Very low-quality evidence found that the rate of recurrence of DPVNS was reduced by peri-operative radiotherapy (OR = 0.31, 95% CI 0.14 to 0.70; p = 0.01). Very low-quality evidence suggested that the rate of recurrence of LPVNS was not related to the surgical approach. . This meta-analysis suggests that open synovectomy or synovectomy combined with peri-operative radiotherapy for DPVNS is associated with a reduced rate of recurrence. Large long-term prospective multicentre observational studies, with a focus on both rate of recurrence and function, are required to confirm these findings.

It is generally accepted that there is a high rate of local recurrence following surgical excision of chordoma of the sacrum, even if the margins of excision appear clear. There is uncertainty as to whether the addition of postoperative radiotherapy may decrease the risk of local recurrence, particularly if there are close or involved margins. We aimed to determine the effect of conventional radiotherapy, in the post-operative setting, on the effect of local recurrence, metastases and patient survival in a multi-centre study. Methods. 57 patients were identified from the combined databases of the RNOH and ROH, who underwent surgical excision of a primary sacral chordoma and who had a minimum of three years follow-up. Results. There were 17 women and 40 men, with a median age of 64 (25-81 range). Median tumour length was 10cm (2-20 range). 22 of the 57 patients died. Survival was 60% at 5 years and 45% at ten years. 28 of the 57 patients developed local recurrence (49%) and margins of excision did not affect the rates of local recurrence. Adjuvant radiotherapy was used in 9 patients, to with intra-lesional resections, five marginal and two wide. Without radiotherapy the local recurrence rate was 45% at five years. With radiotherapy, the local recurrence rate was 62.5% at five years. There were no statistically significant differences between the two. Conclusions. Local recurrence rates for chordoma are high. The biology of the tumour and its extent may well be predictive of local recurrence rather than just margin status per se. Radiotherapy, in the small numbers of patients in this study, seemed not to have an effect in preventing local recurrence. The role of high dose conventional radiotherapy may make surgery for these tumours obsolete

We investigated whether the presence of a pathological fracture increased the risk of local recurrence in patients with a giant cell tumour (GCT) of bone. We also assessed if curettage is still an appropriate form of treatment in the presence of a pathological fracture. We conducted a comprehensive review and meta-analysis of papers which reported outcomes in patients with a GCT with and without a pathological fracture at presentation. We computed the odds ratio (OR) of local recurrence in those with and without a pathological fracture. . We selected 19 eligible papers for final analysis. This included 3215 patients, of whom 580 (18.0%) had a pathological fracture. The pooled OR for local recurrence between patients with and without a pathological fracture was 1.05 (95% confidence interval (CI) 0.66 to 1.67, p = 0.854). Amongst the subgroup of patients who were treated with curettage, the pooled OR for local recurrence was 1.23 (95% CI 0.75 to 2.01, p = 0.417). . A post hoc sample size calculation showed adequate power for both comparisons. . There is no difference in local recurrence rates between patients who have a GCT of bone with and without a pathological fracture at the time of presentation. The presence of a pathological fracture should not preclude the decision to perform curettage as carefully selected patients who undergo curettage can have similar outcomes in terms of local recurrence to those without such a fracture.

The outcome for patients with Ewing's sarcoma recurrence is poor. Local recurrences occur in 8%-25%of these patients. The aim of the study was to analyze the patients who had a local recurrence to identify factors predicting the local recurrence and if it could be prevented. Methods. A retrospective analysis of 650 patients who had a diagnosis of Ewing's sarcoma treated between 1975 and 2009 at a single institution was performed and 64 patients (10%) who had a local recurrence were identified and analysed. Results. Fifteen patients had metastases at diagnosis.20 patients had chemotherapy and radiotherapy only while 44 had chemotherapy and surgery +/− post op radiotherapy. Thirteen patients who were suitable for post –operative radiotherapy could not receive the treatment due to various reasons like biological reconstruction. The estimated 5 years survival for the patients was 15%. The risk of local recurrence is higher if the tumour is located in the axial skeleton, treatment with chemotherapy and radiotherapy alone [location and size of the tumour precluding surgery]. The risk of local recurrence is higher if the tumour was in the fibula or radius. One out of three patients who have good response to chemotherapy still went on to develop a LR. The use of biological reconstruction and younger age group often resulted in deferral of post-operative radiotherapy. Location and type of treatment can predict LR. Surgery with clear margins and post-operative radiotherapy given when indicated may reduce the incidence of LR

Introduction. Current practice in the UK is to perform clinical follow up and CXR on patients with sarcomas with the use of cross-sectional imaging reserved for high clinical suspicion of recurrence. We aimed to assess the effectiveness of this policy by investigating patients who developed local recurrence (LR) after previous treatment of a bone or soft tissue sarcoma (STS). Additionally, we aimed to determine whether size and extent of LR at diagnosis of recurrence affected subsequent management. Method. We reviewed clinical records and imaging of all patients in the previous 5 years (01/01/2005–01/07/2010) with diagnosed LR to investigate: how it was diagnosed, site and size of recurrence and management. A value judgement was made as to whether earlier diagnosis may have altered treatment and/or outcome. Results. A total of 161 patients were identified; 87 patients with STS and 74 with bone sarcoma. Median time from diagnosis to LR was 27 months for both bone sarcoma and STS, but was shorter for high grade tumours. 115 cases (71%) were identified by the patient, 30 by routine imaging (19%), 15 by a doctor, and 1 by district nurse. Average size at time of LR was 7cm for STS and 8cm for bone sarcomas. 79 of the patients (49%) could have had their LR diagnosed earlier with routine imaging. Of these, 53 would have received the same treatment, but 26 would have had different treatment. Of those, 23 would probably have had a smaller operation and 3 could have avoided amputation. Discussion. Earlier diagnosis could have led to simpler surgery in 1/3 of those patients with potential to have their LR diagnosed earlier. This raises the question as to whether a more aggressive policy of follow up with regular imaging (either MRI or ultrasound) could detect LR earlier leading to improved outcomes

We have investigated the significance of local recurrence on survival in 173 patients with localised soft-tissue sarcomas of the limbs and of the trunk. The overall survival rates at five and ten years were 75.2% and 68.0%, respectively. After definitive surgery at our hospitals, there was local recurrence in 25 patients (14.5%). After inadequate operations elsewhere, there was a higher incidence of late local recurrence (28.3%), in comparison with those with primary tumours treated by us (9.0%), or patients referred to us immediately after inadequate surgery elsewhere (10.2%). Because of small numbers these differences in the survival rates were not statistically significantly different. Univariate survival analysis showed that local recurrence after definitive surgery (p = 0.006) together with the histological grade (p = 0.0002), the size of the tumour (p = 0.002), its depth in relation to deep fascia (p = 0.003), and the surgical margin (p = 0.0001) were the significant prognostic factors. Local recurrence at the initial presentation did not affect survival. Multivariate analysis showed that local recurrence after definitive surgery also lost its apparent prognostic significance

We retrospectively studied local recurrence of giant cell tumour in long bones following treatment with curettage and cementing in 137 patients. The median follow-up time was 60 months (3 to 166). A total of 19 patients (14%) had at least one local recurrence, the first was diagnosed at a median of 17 months (3 to 29) after treatment of the primary tumour. There were 13 patients with a total of 15 local recurrences who were successfully treated by further curettage and cementing. Two patients with a second local recurrence were consequently treated twice. At the last follow-up, at a median of 53 months (3 to 128) after the most recent operation, all patients were free from disease and had good function. We concluded that local recurrence of giant cell tumour after curettage and cementing in long bones can generally be successfully treated with further curettage and cementing, with only a minor risk of increased morbidity. This suggests that more extensive surgery for the primary tumour in an attempt to obtain wide margins is not the method of choice, since it leaves the patient with higher morbidity with no significant gain with respect to cure of the disease

Introduction. Local recurrence of Giant cell tumours of bone (GCT) is considered the main complication of surgical treatment (50%). Intra-lesional curettage with adjuvants like phenol or polymethylmethacrylate (PMMA) is recommended as initial treatment, decreasing the risk of recurrence. However, risk factors for local recurrence in skeletal GCT have not yet been firmly established and a golden standard for treatment remains controversial. Aim of this study is identification of risk factors for recurrence in GCT, specifically after intra-lesional curettage with or without adjuvants. Methods. In a retrospective single-institution study 191 patients treated for GCT between 1964 and 2009 were included. Mean follow-up was 111 months (range 12-415). The recurrence-free survival and hazards for different treatment strategies and various patient and tumour characteristics were determined. Results. Overall risk of recurrence was 36.1% (n=66, 95% CI: 28.3-42.1). Recurrence rate after wide resection was 20%, after curettage with adjuvants 33% and after curettage alone 77%. Hogendoorn-grade III (Hazard Ratio: 5.7, p⋋0.001), localisation in axial skeleton (HR: 3.7, p⋋0,001), primary treatment in a non-specialised centre (HR: 2.8, p⋋0.001) and extension into soft tissue (HR: 2.0, p=0.02) were significant risk factors for local recurrence. Curettage with adjuvants proved superior to curettage alone (p⋋0.004 p=0.07, HR: 0.54), but the application of both PMMA and phenol did not present a significantly better outcome than PMMA alone (HR: 1.07, p=0.9). Discussion. Of all possible risk factors only soft tissue extension and localisation in distal radius significantly influenced the risk of local recurrence for all treatments. We found that high-grade tumours and localisation in the axial skeleton were additional risk factors for local recurrence after intra-lesional surgery. Although wide resection increases morbidity, it can be the therapy of choice in high risk patients. Intra-lesional therapy can be advised for low risk patients using curettage adjuvants and PMMA

We have reviewed 13 operations on 11 patients using curettage and polymethylmethacrylate cement for giant-cell tumour of bone (GCT) to assess the value of radiology in the early detection of recurrence. There were four recurrences, the most specific radiological sign on plain radiography was lysis of 5 mm or more at the cement-bone interface. This preceded clinical signs by a mean of four months and was identified at a mean of 3.75 months after operation. There was not always a complete sclerotic margin around the cement, but when it was present, there was never evidence of recurrence. MRI was helpful in assessing cases with evidence of recurrence. Frequent surveillance with plain radiography should continue for one year after operation irrespective of clinical signs of recurrence. When the appearance of the plain radiographs suggests recurrence, MRI should be performed and followed by image-guided needle biopsy

Objective. To evaluate the rise in impedance during percutaneous radiofrequency thermo coagulation (PRFTC) of osteoid osteomas as a predictor of local recurrence. Design and Patients. 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. Results. In 19 procedures, an increase in impedance was measured—no recurrences have occurred in this group to date. In 5 procedures, no increase in impedance was seen (3 non-diaphyseal, 2 diaphyseal), and 1 recurrence has been seen in this group to date. This difference is statistically significant with a P value of .05

We considered whether a positive margin occurring after resection of a soft-tissue sarcoma of a limb would affect the incidence of local recurrence. Patients with low-grade liposarcomas were expected to be a low-risk group as were those who had positive margins planned before surgery to preserve critical structures. Two groups, however, were expected to be at a higher risk, namely, patients who had undergone unplanned excision elsewhere with a positive margin on re-excision and those with unplanned positive margins occurring during primary resection. Of 566 patients in a prospective database, 87 with positive margins after limb-sparing surgery and adjuvant radiotherapy were grouped according to the clinical scenario by an observer blinded to the outcome. The rate of local recurrence differed significantly between the two low- (4.2% and 3.6%) and the two high-risk groups (31.6% and 37.5%). This classification therefore provides useful information about the incidence of local recurrence after positive-margin resection

Local recurrence along the biopsy track is a known complication of percutaneous needle biopsy of malignant musculoskeletal tumours. In order to completely excise the track with the tumour its identification is essential, but this becomes increasingly difficult over time. In an initial prospective study, 22 of 45 patients (48.8%) identified over a three-month period, treated by resection of a musculoskeletal tumour, had an unidentifiable biopsy site at operation, with identification statistically more difficult after 50 days. We therefore introduced the practice of marking the biopsy site with India ink. In all 55 patients undergoing this procedure, the biopsy track was identified pre-operatively (100%); this difference was statistically significant. We recommend this technique as a safe, easy and accurate means of ensuring adequate excision of the biopsy track. Cite this article: Bone Joint J 2013;95-B:250–3

Introduction

The aim of this study was to investigate the results of a series of cases from a single institution with respect to local disease control and patient survival to determine prognostic factors.

Methods

Electronic patient records were reviewed on all patients with STS between February 1963 and January 2007. 2445 patients had over 30 types of STS. 1639 (67%) had not received any treatment prior to presentation, however, 770 patients (32%) had undergone a previous attempted excision. Survival analyses were done using Kaplan Meier and Cox regression analyses, however, for prognostic factor analysis, only patients presenting without prior treatment were included.

Aims. Tenosynovial giant cell tumour (TGCT) is a rare benign tumour of the musculoskeletal system. Surgical management is fraught with challenges due to high recurrence rates. The aim of this study was to describe surgical treatment and evaluate surgical outcomes of TGCT at an Australian tertiary referral centre for musculoskeletal tumours and to identify factors affecting recurrence rates. Methods. A prospective database of all patients with TGCT surgically managed by two orthopaedic oncology surgeons was reviewed. All cases irrespective of previous treatment were included and patients without follow-up were excluded. Pertinent tumour characteristics and surgical outcomes were collected for analysis. Results. There were 111 total cases included in the study; 71 (64%) were female, the mean age was 36 years (SD 13.6), and the knee (n = 64; 57.7%) was the most commonly affected joint. In all, 60 patients (54.1%) had diffuse-type (D-TGCT) disease, and 94 patients (84.7%) presented therapy-naïve as "primary cases" (PC). The overall recurrence rate was 46.8% for TGCT. There was a statistically significant difference in recurrence rates between D-TGCT and localized disease (75.0% vs 13.7%, relative risk (RR) 3.40, 95% confidence interval (CI) 2.17 to 5.34; p < 0.001), and for those who were referred in the ”revision cases” (RC) group compared to the PC group (82.4% vs 48.9%, RR 1.68, 95% CI 1.24 to 2.28; p = 0.011). Age, sex, tumour volume, and mean duration of symptoms were not associated with recurrence (p > 0.05). Conclusion. Recurrence rates remain high even at a tertiary referral hospital. Highest rates are seen in D-TGCT and “revision cases”. Due to the risks of recurrence, the complexity of surgery, and the need for adjuvant therapy, this paper further supports the management of TGCT in a tertiary referral multi-disciplinary orthopaedic oncology service.

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. Methods. 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. Results. The ten-year disease-specific survival was 76%. High tumour grade (hazard ratio (HR) 4.27; p = 0.016) and a total resection of the scapula (HR 3.84; p = 0.015) were associated with worse survival. The ten-year metastasis-free and local recurrence-free survivals were 82% and 86%, respectively. Total scapular resection (HR 6.29; p = 0.004) was associated with metastatic disease and positive margins were associated with local recurrence (HR 12.86; p = 0.001). At final follow-up, the mean shoulder forward elevation and external rotation were 79° (SD 62°) and 27° (SD 25°), respectively. The most recent functional outcomes evaluated included the mean Musculoskeletal Tumor Society Score (76% (SD 17%)), the American Shoulder and Elbow Score (73% (SD 20%)), and the Simple Shoulder Test (7 (SD 3)). Preservation of the glenoid (p = 0.001) and scapular spine (p < 0.001) improved clinical outcomes; interestingly, preservation of the scapular spine without the glenoid improved outcomes (p < 0.001) compared to preservation of the glenoid alone (p = 0.05). Conclusion. Resection of the scapula is a major undertaking with an oncological outcome related to tumour grade, and a functional outcome associated with the status of the scapular spine and glenoid. Positive resection margins are associated with local recurrence. Cite this article: Bone Joint J 2023;105-B(12):1314–1320

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. Methods. A total of 354 consecutive patients with a GCTB underwent joint salvage by curettage and reconstruction with bone graft and/or cement or en bloc resection. Patient, tumour, and treatment factors were analyzed for their impact on LR. Patients treated with denosumab were excluded. Results. There were 53 LRs (15%) at a mean 30.5 months (5 to 116). LR was higher after curettage (18.4%) than after resection (4.6%; p = 0.008). Neither pathological fracture (p = 0.240), Campanacci grade (p = 0.734), soft-tissue extension (p = 0.297), or tumour size (p = 0.872) affected the risk of recurrence. Joint salvage was possible in 74% of patients overall (262/354), and 98% after curettage alone (262/267). Of 49 patients with LR after curettage, 44 (90%) underwent repeated curettage and joint salvage. For patients treated by curettage, only age less than 30 years (p = 0.042) and location in the distal radius (p = 0.043) predicted higher LR. The rate of LR did not differ whether cement or bone graft was used (p = 0.753), but may have been reduced by the use of hydrogen peroxide (p = 0.069). Complications occurred in 15.3% of cases (54/354) and did not differ by treatment. Conclusion. Most patients with a GCTB can undergo successful joint salvage by aggressive curettage, even in the presence of a soft-tissue mass, pathological fracture, or a large lesion, with an 18.4% risk of local recurrence. However, 90% of local relapses after curettage can be treated by repeat joint salvage. Maximizing joint salvage is important to optimize long-term function since most patients with a GCTB are young adults. Younger patients and those with distal radius tumours treated with joint-sparing procedures have a higher rate of local relapse and may require more aggressive treatment and closer follow-up.
