- Abstract
Introduction: Previous studies have highlighted the association between insurance status and poor outcomes after surgical treatment of sarcomas in the United States.1-3 It is unclear how much of this disparity is mediated by confounding factors such as medical comorbidities and socioeconomic status and how much can be explained by barriers to care caused by insurance status., Methods: Surveillance, Epidemiology, and End Results-Medicare linkage data were procured for 7,056 patients undergoing treatment for bone and soft-tissue sarcomas in the extremities diagnosed between 2006 and 2013. A Cox proportional hazards model was used to assess the relative contributions of insurance status, medical comorbidities, tumor factors, treatment characteristics, and other demographic factors (race, household income, education level, and urban/rural status) to overall survival., Results: Patients with Medicaid insurance had a 28% higher mortality rate over the period studied, compared with patients with private insurance (hazard ratio, 1.28; 95% confidence interval, 1.03 to 1.60, P = 0.026), even when accounting for all other confounding variables. The 28% higher mortality rate associated with having Medicaid insurance was equivalent to being approximately 10 years older at the time of diagnosis or having a Charlson comorbidity index of 4 rather than zero (hazard ratio, 1.27)., Discussion: Insurance status is an independent predictor of mortality from sarcoma, with 28% higher mortality in those with pre-expansion Medicaid.4,5 This association between insurance status and higher mortality held true even when accounting for numerous other confounding factors. Additional study is necessary into the mechanism for this healthcare disparity for the uninsured and underinsured, as well as strategies to resolve this inequality., (Copyright © 2022 by the American Academy of Orthopaedic Surgeons.)

- Abstract
Rotationplasty is an established technique that is indicated as part of the surgical reconstruction for certain patients with primary bone tumors around the knee who undergo tumor resection. There is considerable variation in the application of rotationplasty by surgeons as well as acceptance of the procedure by patients who may be candidates for this procedure. We qualitatively studied the decision-making process of families of patients who had undergone rotationplasty by interviewing 4 patients and their families using semi-structured interviews. Thematic analysis identified the following themes that were important in the decision-making process: (1) the desire for good information sources, (2) finding value in meeting with other patients who had been faced with a similar decision, (3) prioritizing function over cosmesis, (4) a desire to limit the need for revision surgeries, and (5) accepting that a return to normalcy is not an option with a surgery. Physicians and patients faced with a similar decision can benefit from a better understanding of the process, and by the normalization of anxieties and concerns that they may experience., Competing Interests: Declaration of Conflicting Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)

- Abstract
Background: The complexity of sarcoma surgery often justifies surgical assistants of higher levels of academic training: senior residents, fellows, or co-surgeons. The association between the level of training of assistants and outcomes of these procedures has yet to be studied., Methods: The Current Procedural Terminology (CPT) codes comprising the "core" procedures for musculoskeletal oncology fellowships were gathered. After CPTs primarily capturing nononcologic procedures were excluded, the National Surgical Quality Improvement Program (NSQIP) database was used to find procedures with these CPTs. The severity of complications was assessed using the Severity Weighting of Postoperative Adverse Events in Orthopedic Surgery (SWORD) score. Resident/fellow presence was analyzed both as a binary variable and stratified by level of training., Results: In 159 cases meeting inclusion criteria, higher-level assistants were associated with increased rate of any complication ( p =0.006) and greater need for transfusion ( p =0.001) but also tended to be used in cases of longer duration ( p =0.001) and with higher total work relative value units (wRVUs) ( p =0.001). Multivariate analysis showed that while higher-wRVU procedures persisted as an independent predictor of increased complications (OR 1.028 per RVU unit, p =0.002), neither the presence nor level of training of assistants had an independent effect on complication rates. Other independent predictors of 30-day complications were treatment comorbidity (OR 3.433, p =0.010) and lower extremity location of the tumor (OR 4.393, p =0.006). Severity of complications did not differ between any of the groups on either univariate or multivariate analysis., Conclusions: Trainees of higher levels of academic training tend to be present for longer, higher-complexity musculoskeletal oncology cases, but the overall severity of complications from these do not significantly differ from lower-risk cases without trainees. Orthopedic oncologists may reassure patients that the presence of trainees and co-surgeons is not only safe but it may also help reduce the severity of complications in more complex procedures., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2021 Eugene S.

- Abstract
Objective: Compared with radical resection alone, perioperative radiation therapy (RT) combined with neurovascular preserving surgery is the standard for the management of virgin soft-tissue sarcomas. Yet, the optimal management of a local recurrence remains unclear. We report outcomes of patients with locally recurrent soft-tissue sarcoma treated with resection and reirradiation at the University of Florida., Materials and Methods: We reviewed the records of patients treated with primary conservative surgery and radiation for soft-tissue sarcoma followed by salvage resection and reirradiation for a local recurrence at our institution., Results: We analyzed 23 patients treated between 1976 and 2014 (median follow-up, 46 mo). Tumor sites included: proximal extremity, 11 patients; trunk, 6; distal extremity, 5; and head and neck, 1. All patients had conservative gross total resection of their recurrent tumor, without amputation. For reirradiation, 16 patients received external-beam RT alone, 6 received external-beam RT and brachytherapy, and 1 received brachytherapy alone. Two patients received chemotherapy. After retreatment, the 5-year overall survival, cause-specific survival, local control, and distant control rates were 39%, 42%, 46%, and 60%, respectively. Ten patients experienced local recurrences, 1 experienced regional recurrence, and 9 developed distant metastases. Retreatment-related complications ranged from delayed wound healing to limb amputation; 8 patients required amputation. Only 3 patients remained disease-free at last follow-up. No statistically significant associations were found between treatment factors (eg, RT dose) and local control., Conclusions: Achieving local control of recurrent soft-tissue sarcoma is challenging. Treatment with reoperation and reirradiation can lead to debilitating complications affecting function and quality of life., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

- Abstract
Neurofibromatosis type 1 (NF1) is an autosomal dominant tumor syndrome in which benign plexiform neurofibromas are at risk of transforming into malignant peripheral nerve sheath tumors (MPNSTs), a very rare soft-tissue sarcoma. The prognosis of patients with MPNSTs is poor, with most studies reporting <50% survival at five years. However, studies evaluating MPNSTs are limited and report heterogeneous results. Because no MPNST-specific evidence-based treatment guideline exists, individual institutional experiences are very informative to the field. The main objective of this study was to investigate and report MPNST prognostic clinical and genetic biomarkers from our institution's Orthopedics service experience treating 20 cases from 1992 to 2017. Most patients were treated with resection and adjuvant radiation. Extended follow-up, averaging 11.4 years (ranging 1.1 to 25.1), revealed excellent five-year survival rates: 70% for overall and 60% for metastatic disease. An S100 B immunonegative tumor phenotype was associated with a significantly worse outcome than MPNSTs with positive S100 B stain. In addition, NF1 gene mutation analysis was performed on 27 families with NF1 in which at least one affected family member developed MPNSTs. Of the 27 NF1 germline mutations, five were large deletions spanning (or nearly spanning) the gene (18.5%), substantially more than such deletions in NF1 in general, consistent with increased risk of MPNSTs in such cases., Competing Interests: The authors declare that there are no conflicts of interest with regard to this study., (Copyright © 2021 Daniel K.

- Abstract
Brain metastases are a rare occurrence in patients with sarcoma. The prognosis for patients is poor, and treatment can contribute to considerable morbidity. We sought to examine the experience of our institution in managing these patients over a period of 17 years. We performed a retrospective cohort study of patients managed for sarcoma of the extremity or trunk who developed brain metastases from 2000 to 2017. Clinical data were analyzed and we assessed survival outcomes. 14 patients presenting at a mean age of 46.7 years were included. All patients were treated with radiotherapy for their brain metastases. 3 patients underwent surgical excision of their intracranial metastases. Two patients were treated with radium-223 dichloride. Kaplan-Meier survival analysis and the log rank test were used to calculate the survival probability, and to compare patient subgroups. All patients in this study developed lung or bone metastases at a mean interval of 13.3 months prior to the development of brain metastasis. The median interval from diagnosis of a brain metastasis to death was 3.6 months. The Kaplan-Meier survival probability at 6 months was 28.6%, and 14.3% at 1 year. Surgery was not found to be associated with increased survival. Patients with cerebellar metastasis had increased survival probability as compared to those with cerebral metastasis. Patients with extremity or trunk sarcoma who develop brain metastases frequently develop lung or bone metastases in the year preceding their diagnosis of brain metastasis. Patients with cerebellar metastasis may have better survival than those with cerebral metastasis, and an aggressive treatment approach should be considered. Despite aggressive treatment, the prognosis is grim., Competing Interests: Conflict of interest: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2020.)

- Abstract
Background: The Patient Reported Outcomes Measurement Information System (PROMIS) is a tool developed by the National Institutes of Health that allows comparisons across conditions or even the United States (U.S.) general population., Objectives: Our purpose was to compare PROMIS outcomes between patients who underwent a planned resection to those who underwent an initial unplanned excision of their sarcoma followed by a definitive oncologic resection. We then compared these groups to the U.S. general population., Methods: Eighty-five patients were included and were divided into those who underwent an initial planned resection (67) and unplanned excision (18). These patients were then further categorized based on the length of follow-up since their last surgery, either early (<12 months) or late (>12 months)., Results: We evaluated seven PROMIS domains and found no differences between patients who underwent planned resection versus those who underwent an initial unplanned excision followed by a wide resection of the previous wound bed. When compared to the U.S. population, both cohorts demonstrated significantly improved scores in several emotional health domains., Conclusions: Patients who undergo an unplanned excision followed by a definitive oncologic procedure have similar PROMIS scores compared to patients who undergo an initial planned resection.

- Abstract
Background: Periosteal osteosarcoma is a rare surface-based variant with a lower propensity to metastasis and better prognosis than conventional osteosarcoma. The literature supporting survival benefit with adjuvant chemotherapy is lacking. Our institutional practice is for chemotherapy to be offered to patients with high-grade disease., Methods: We conducted a retrospective cohort study of patients managed for periosteal osteosarcoma from 1970 to 2015 analyzing the survival outcomes and assessing for any relationship of survival to patient- or treatment-related factors. 18 patients were included. The study population presented at a mean of 20.8 years and was followed for a mean of 10.7 years. Factors assessed for an association with survival included age, size of tumor, use of chemotherapy, presence of medullary involvement, presence of high-grade disease, local recurrence, and site of disease. Kaplan-Meier survival analysis and Cox proportional hazard regression were performed to calculate the survival rates and to assess for the effect of any factor on survival., Results: 10-year overall survival rate was 77.1%, and 10-year event-free survival rate was 66.4%. No factor was found to have an association with overall or event-free survival., Conclusion: These findings add to the available evidence which has failed to find any survival benefit from chemotherapy; patients with this rare disease and their families should be counselled regarding the unclear role of chemotherapy in this rare subtype of osteosarcoma.

- Abstract
Background: The most common site of sarcoma metastasis is the lung. Surgical resection of pulmonary metastases and chemotherapy are treatment options that have been employed, but many patients are poor candidates for these treatments for multiple host or tumor-related reasons. In this group of patients, radiation might provide a less morbid treatment alternative. We sought to evaluate the efficacy of radiotherapy in the treatment of metastatic sarcoma to the lung., Methods: Stereotactic body radiotherapy (SBRT) was used to treat 117 pulmonary metastases in 44 patients. Patients were followed with serial computed tomography imaging of the chest. The primary endpoint was failure of control of a pulmonary lesion as measured by continued growth. Radiation-associated complications were recorded., Results: The majority of patients (84%) received a total dose of 50 Gy per metastatic nodule utilizing an image-guided SBRT technique. The median interval follow-up was 14.2 months (range 1.6-98.6 months). Overall survival was 82% at two years and 50% at five years. Of 117 metastatic nodules treated, six nodules showed failure of treatment (95% control rate). Twenty patients (27%) developed new metastatic lesions and underwent further SBRT. The side effects of SBRT included transient radiation pneumonitis ( n =6), cough ( n =2), rib fracture ( n =1), chronic pain ( n =1), dermatitis ( n =1), and dyspnea ( n =1)., Conclusion: Stereotactic body radiotherapy is an effective and safe treatment for the ablation of pulmonary metastasis from sarcoma. Further work is needed to evaluate the optimal role of SBRT relative to surgery or chemotherapy for treatment of metastatic sarcoma.

- Abstract
Background: Parosteal osteosarcoma is a rare tumor with increased survival compared to conventional high-grade osteosarcoma. Due to this increased survival comes the need for reconstructive options that provide good long-term functional results. Current treatment methods include geographic resection with allograft reconstruction versus resection and reconstruction with a distal femoral replacement., Purpose: Our purpose was to compare the long-term functional outcomes of distal femoral replacements to allograft reconstructions, using the musculoskeletal tumor society (MSTS) scoring system., Methods: After querying our database, 12 patients were identified and completed a MSTS questionnaire., Results: There was no difference in functional outcomes between the cohorts at an average of 14 years follow up for the endoprosthetic group and 25 years of follow up for the geographic resection group., Conclusion: At long-term follow-up, patients who undergo a distal femoral replacement for a parosteal osteosarcoma have no difference in functional outcomes compared to those who undergo an allograft reconstruction.Level of Evidence: IV.

- Abstract
Objective: To evaluate outcomes after conservative resection and radiotherapy (RT) for soft-tissue sarcoma (STS) of the distal extremity, with assessment of functional quality of life using the validated Toronto Extremity Salvage Score (TESS) questionnaire and Common Terminology Criteria for Adverse Events (CTCAE), v4.0., Methods: Thirty-three patients with STS involving the hand/wrist (N=18) or foot/ankle (N=15) complex received adjuvant RT with conservative resection and were evaluated for local tumor control, survival, toxicities, and preservation of objective functional ability. Eight patients were treated with preoperative RT (median dose, 50.4 Gy) and 25 with postoperative RT (median dose, 61.8 Gy). Median follow-up was 11.5 years. Functional outcomes were measured using TESS; patients with amputations were excluded from the TESS analysis. Adverse events related to gait, limb edema, skin infection, wound complication, and wound dehiscence were assessed using the CTCAE., Results: The 5- and 10-year local control rates were both 90%. The 10-year cause-specific, absolute, and distant metastasis-free survival rates were 97%, 87%, and 84%, respectively. Three patients had an amputation for reasons other than local recurrence or treatment complications and underwent amputation for patient preference. One third of the subjects (11/33 patients) were able to complete the TESS questionnaire; scores ranged from 88 to 100 (mean, 98.2). CTCAEv4 acute adverse events occurred in 2 cases: 1 patient had a grade 3 skin infection and 1 had a grade 2 wound complication of dehiscence., Conclusions: For management of distal extremity STS, the combination of adjuvant RT and conservative surgery achieves excellent local control and overall survival with few adverse events. In addition, through application of the TESS survey instrument, we have demonstrated that this treatment plan achieves robust functional preservation objectively and quantifiably.

Mendenhall WM, Reith JD, Scarborough MT, Stechmiller BK, and Mendenhall NP
- Abstract
Purpose: To review the treatment and outcomes of patients with mesenchymal chondrosarcomas (MC)., Materials and Methods: Review of the pertinent literature., Results: MC is a rare aggressive small round blue cell malignancy that may arise in either bone or soft tissue. It usually presents in the 2
nd or 3rd decade of life and exhibits an approximately equal gender predilection. Patients usually present with pain and swelling. The majority of MCs arise in either the trunk or extremities. Distant metastases are present at diagnosis in about 15% of patients. The most common sites for distant metastases are lung and bone. The optimal treatment is surgery. Although the role of adjuvant chemotherapy is unclear, an anthracycline-based chemotherapy regimen combined with ifosfamide or cisplatin, may be considered. Adjuvant radiation therapy (RT) is employed for patients with close (<5 mm) or positive margins as well as those with incompletely resectable tumors. The most common mechanism of recurrence is hematogenous dissemination. Although most recurrences are observed within 5 years of treatment, late recurrences are not unusual. The likelihood of successful salvage in the event of a recurrence is modest. The overall survival rates for all patients are approximately 50% at 5 years and 40% at 10 years. The overall survival rates for the subset of patients with localized disease that is resected are approximately 70% to 80% at 5 years and 60% at 10 years., Conclusion: Patients with MCs are optimally treated with surgery. The role of adjuvant chemotherapy is uncertain. However, given the relatively high risk of recurrence, adjuvant chemotherapy should be considered in medically fit patients. Radiation therapy should be considered for those with incompletely resectable tumors and those with inadequate margins., Competing Interests: Conflicts of interest: The authors have no conflicts of interest to disclose., (© Copyright 2016 International Journal of Particle Therapy.)- Published

- Abstract
Purpose: To evaluate the effectiveness of definitive or adjuvant external beam proton therapy on survival in patients with chordomas and chondrosarcomas of the spine., Methods and Materials: Between March 2007 and May 2013, 51 patients with a median age of 58 years (range, 22-83 years) with chordoma (n=34) or chondrosarcomas (n=17) of the sacrum (n=21), the cervical spine (n=20), and the thoracolumbar spine (n=10) were treated with external beam proton therapy to a median dose of 70.2 Gy(RBE) [range, 64.2-75.6 Gy(RBE)] at our institution. Distant metastases, overall survival, cause-specific survival, local control, and disease-free survival were calculated., Results: The mean follow-up time was 3.7 years (range, 0.3-7.7 years). Across all time points, 25 patients experienced disease recurrence: 18 local recurrences, 6 local and distant recurrences, and 1 distant metastasis. The 4-year rates of overall survival and cause-specific survival were 72%; disease-free survival was 57%, local control was 58%, and freedom from distant metastases was 86%. The median time to local progression was 1.7 years (range, 0.2-6.0 years), and the median time to distant progression was 1.6 years (range, 0.2-6.0 years). The risk factors for local recurrence were age ≤58 years (62% vs 26%; P=.04) and recurrence after prior surgery (29% vs 81%; P=.01). Secondary cancers developed in 2 patients: B-cell lymphoma 5.5 years after treatment and bladder cancer 2 years after treatment. We observed the following toxicities: sacral soft tissue necrosis requiring surgery (n=2), T1 vertebral fracture requiring fusion surgery (n=1), chronic urinary tract infections (n=1), surgery for necrotic bone cyst (n=1), and grade 2 bilateral radiation nephritis (n=1)., Conclusion: High-dose proton therapy controls more than half of spinal chordomas and chondrosarcomas and compares favorably with historic photon data. Local progression is the dominant mode of treatment failure and may be reduced by treating patients at the time of initial diagnosis. The impact of age is a novel finding of this study., (Copyright © 2016 Elsevier Inc. All rights reserved.)

- Abstract
Background: Pulmonary surveillance protocols following sarcoma excision based on clinical evidence and outcomes are limited in current literature. The purpose of this study was to determine the method, frequency, and reasoning behind pulmonary surveillance strategies in patients treated for sarcoma among members of the Musculoskeletal Tumor Society (MSTS)., Methods: SurveyMonkey, an online survey tool, was used to create and distribute a questionnaire to 211 members of the MSTS in 2011. The 16 questions focused on current pulmonary surveillance algorithms and their reasoning., Results: Of the surveyed members of the MSTS, 65% follow high-grade sarcoma with routine chest CT scans. Most disagreement involved low-grade sarcomas, where radiographs (34%), routine CT (33%), or selective CT scans (31%) were evenly distributed. Selective CT scans in low-grade lesions were warranted with an indeterminate nodule on prior CT (81%), local recurrence (40%), or large/ deep tumor characteristics (31%). Most protocols were based on continuation of training protocols (46%), clinician's interpretation of the current literature (23%), or personal experience (14%)., Conclusions: Significant clinician variability exists in terms of pulmonary surveillance of sarcomas, most notably in low-grade lesions. The results of this study represent an area in need of further study to develop an evidence-based protocol for sarcoma pulmonary surveillance.

- Abstract
Background: Extraskeletal osteosarcoma is a rare tumor with a poor prognosis. The purpose of this study is to examine the oncologic outcomes of this disease as they relate to surgical treatment and use of adjuvant therapies., Methods: We retrospectively analyzed all patients treated at our institution for high-grade extraskeletal osteosarcoma of the limb or chest wall. We recorded demographic data, presenting stage, surgical margin, use of adjuvant chemotherapy or radiation, incidence of local recurrence, metastases, and death. Overall and event-free survival were calculated using Kaplan-Meier survival methods., Results: There were 12 patients treated with primary wide resection or re-excision of a previously operated tumor bed. Four patients presented with metastases. Seven patients received chemotherapy and four patients received radiation therapy. There were two local recurrences, six patients developed new metastases, and nine patients died. There was no difference in overall survival in patients who received chemotherapy. There was, however, a trend towards increased length of survival in patients who received chemotherapy compared to those who did not (16.4 months vs. 9.3 months, p=0.16)., Conclusions: Despite no difference in overall survival, patients treated with adjuvant chemotherapy have a trend towards increased length of survival. We suggest that extraskeletal osteosarcoma be treated with standard osteosarcoma chemotherapy regimens in addition to wide resection.

- Abstract
Background: Proximal humerus reconstructions after resection of tumors are challenging. Early success of the reverse shoulder arthroplasty for reconstructions has recently been reported. The reverse allograft-prosthetic composite offers the advantage of improved glenohumeral stability compared with hemiarthroplasty for proximal humeral reconstructions as it uses the deltoid for stability., Methods: This article describes the technique for treating proximal humeral tumors, including preoperative planning, biopsy principles, resection pearls, soft tissue tensioning, and specifics about reconstruction using the reverse allograft-prosthetic composite. Two cases are presented along with the functional outcomes with use of this technique. Biomechanical considerations during reconstruction are reviewed, including techniques to improve the deltoid compression force., Results: Reported instability rates are less with reverse shoulder arthroplasty reconstruction as opposed to hemiarthroplasty or total shoulder arthroplasty reconstructions of tumor resections. Reported functional outcomes are promising for the reverse allograft-prosthetic composite reconstructions, although complications are reported., Conclusion: Reverse allograft-prosthetic composites are a promising option for proximal humeral reconstructions, although nonunion of the allograft-host bone junction continues to be a challenge for this technique., (Copyright © 2016 Journal of Shoulder and Elbow Surgery Board of Trustees.

- Abstract
Giant cell tumor (GCT) of the bone is a benign primary bone tumor most often treated with intralesional surgery. Most cases occur around the knee; however, rarely, GCT of bone can occur in the foot and ankle. Limited data exist about the outcomes after treatment of GCT in this location. We retrospectively reviewed an orthopedic oncology database from 1970 to 2010 for cases of GCT of the bone, specifically within the foot and ankle bones. After exclusionary criteria were applied, a total of 19 disease sites in 18 patients were included for analysis. Of the 19 disease sites, 10 recurred. Patients, on average, required 1.7 operations per disease site. Of the 18 patients, 10 required ≥2 operations, 3 required ≥3 operations, and 1 required 4 operations. A total of 4 amputations were performed, including 2 below the knee amputations. Of the 10 patients with recurrence, 2 also had evidence of metastatic disease. The recurrence rates of GCT in the foot and ankle bones appear to be greatest after intralesional curettage without the use of cement. Although the recurrence rates are high, intralesional operations with multiple adjuvant therapy can eventually result in cure., (Copyright © 2015 American College of Foot and Ankle Surgeons.

- Abstract
Background: A giant cell tumor is a benign locally aggressive tumor commonly seen in the distal radius with reported recurrence rates higher than tumors at other sites. The dilemma for the treating surgeon is deciding whether intralesional treatment is adequate compared with resection of the primary tumor for oncologic and functional outcomes. More information would be helpful to guide shared decision-making., Questions/purposes: We asked: (1) How will validated functional scores, ROM, and strength differ between resection versus intralesional excision for a giant cell tumor of the distal radius? (2) How will recurrence rate and reoperation differ between these types of treatments? (3) What are the complications resulting in reoperation after intralesional excision and resection procedures? (4) Is there a difference in functional outcome in treating a primary versus recurrent giant cell tumor with a resection arthrodesis?, Methods: Between 1985 and 2008, 39 patients (39 wrists) were treated for primary giant cell tumor of the distal radius at two academic centers. Twenty patients underwent primary intralesional excision, typically in cases where bony architecture and cortical thickness were preserved, 15 underwent resection with radiocarpal arthrodesis, and four had resection with osteoarticular allograft. Resection regardless of reconstruction type was favored in cases with marked cortical expansion. A specific evaluation for purposes of the study with radiographs, ROM, grip strength, and pain and functional scores was performed at a minimum of 1 year for 21 patients (54%) and an additional 11 patients (28%) were available only by phone. We also assessed reoperations for recurrence and other complications via chart review., Results: With the numbers available, there were no differences in pain or functional scores or grip strength between groups; however, there was greater supination in the intralesional excision group (p=0.037). Tumors recurred in six of 17 wrists after intralesional excision and none of the 15 after en bloc resection (p=0.030). There was no relationship between tumor grade and recurrence. There were 12 reoperations in eight of 17 patients in the intralesional excision group but only one of 11 patients (p=0.049) who underwent resection arthrodesis with distal radius allograft had a reoperation. There were no differences in functional scores whether resection arthrodesis was performed as the primary procedure or to treat recurrence after intralesional excision., Conclusions: Resection for giant cell tumor of the distal radius with distal radius allograft arthrodesis showed a lower recurrence rate, lower reoperation rate, and no apparent differences in functional outcome compared with joint salvage with intralesional excision. Because an arthrodesis for recurrence after intralesional procedures seems to function well, we believe that intralesional excision is reasonable to consider for initial treatment, but the patient should be informed about the relative benefits and risks of both options during the shared decision-making process. Because arthrodesis after recurrence functions similar to the initial resection and arthrodesis, an initial treatment with curettage remains a viable, and likely the standard, mode of treatment for most giant cell tumors of the distal radius unless there is extensive bone loss., Level of Evidence: Level III, therapeutic study.

- Abstract
Background: Imaging studies are essential when evaluating a patient with a musculoskeletal neoplasm, and they represent a potential waste of resources when used inappropriately. The objective of this study was to prospectively evaluate a consecutive series of patients for inappropriate utilization of imaging prior to referral to a tertiary care facility. Our hypothesis was that advanced imaging is overutilized prior to referral of musculoskeletal neoplasms to a tertiary care center., Methods: All new patients referred for evaluation of a musculoskeletal neoplasm were prospectively analyzed over a three-month time period. All pre-referral imaging studies were recorded, including radiographs, computed tomographic scans, magnetic resonance imaging scans, bone scans, and 18-fluorodeoxyglucose positron emission tomography scans. Studies were reviewed by two musculoskeletal radiologists and two orthopaedic oncologists and were defined with use of specific preselected criteria as inappropriate if they were not indicated for diagnosis or treatment, if they required repeating because of excessive time since the study was obtained, or if they had poor image quality or technique., Results: We evaluated 298 consecutive patients (550 imaging studies). The inappropriate utilization rate was 1.5% (three of 204) for radiographs, 36.5% (twenty-three of sixty-three) for computed tomographic scans, 26.7% (fifty-six of 210) for magnetic resonance imaging scans, 45.1% (twenty-three of fifty-one) bone scans, and 45.5% (ten of twenty-two) for positron emission tomography scans. The overall inappropriate use of advanced imaging (magnetic resonance imaging, computed tomography, bone scan, positron emission tomography) was 32.4% (112 of 346 images). With regard to inappropriate use of magnetic resonance imaging, there was no difference between orthopaedic surgeons (28.2%) and primary care physicians (26.5%)., Conclusions: Our data indicate a high prevalence (32.4%) of inappropriate advanced imaging of musculoskeletal tumors prior to referral. This represents a substantial cost to the patient and health-care system, a potential delay of referral, an increase in radiation exposure, and identification of other incidental findings., (Copyright © 2015 by The Journal of Bone and Joint Surgery, Incorporated.)

- Abstract
Objectives: The benefit of radiotherapy (RT) for unresectable hemangioendotheliomas or patients with a high risk of local recurrence is unclear. This single-institution report describes the long-term effectiveness of RT for hemangioendothelioma., Methods: From 1976 to 2009, 14 patients with nonmetastatic hemangioendothelioma were treated with RT at our institution. Median patient age was 45 years (range, 20 to 71 y). Nine patients had hemangioendothelioma of the extremities and 5 had spinal tumors. Eleven tumors originated from bone. Most tumors (n=12) were ≤5 cm in diameter. Nine patients had multifocal tumors. Four patients underwent surgery and postoperative RT, whereas 10 had RT alone. All 4 operative patients had microscopic negative margins. Median RT dose was 52.2 Gy (range, 45 to 60 Gy) for RT alone and 62.2 Gy (range, 60 to 64.8 Gy) for postoperative patients. Seven patients received 1.5-2 Gy once daily and 7 patients received 1.2 Gy twice daily. The median follow-up was 10.3 years (range, 0.1 to 28.0 y)., Results: The 10-year local control, cause-specific survival, and overall survival rates were 100%, 86%, and 73%, respectively. Two patients experienced a distant metastasis and died within 3 months of starting definitive RT. Three patients died of intercurrent illness at a median of 10.5 years after treatment. Nine patients had no evidence of disease at most recent follow-up. No patients experienced greater than grade 1 acute or late toxicity from RT., Conclusions: With no local recurrences and minimal risk of toxicity, our data suggest that RT can effectively manage this disease and radical surgery compromising function or cosmesis may be safely avoided with moderate-dose RT.

- Abstract
Objectives: To evaluate the long-term treatment outcomes for patients with giant cell tumor of bone (GCTB) treated with radiotherapy with or without surgical resection., Methods: This retrospective review includes 34 patients with GCTB treated with megavoltage radiotherapy between January 1973 and January 2008 at the University of Florida. Patients' ages ranged from 16 to 85 years (median, 29). Tumor sizes ranges from 2.5 to 12 cm (median, 4.8 cm) in the maximum dimension. Twenty-one patients received radiation for gross disease, either de novo (22 patients) or recurrent (12 patients). Thirteen patients were treated with postoperative radiation after gross total resection. The median dose was 45 Gy in both the definitive and adjuvant settings., Results: The median follow-up was 16.8 years. The 5- and 10-year local-control (LC) rates were 85% and 81%, respectively. Six patients developed an isolated local recurrence (2/13 treated postoperatively and 4/21 who were treated for gross disease). All 6 patients who developed a local recurrence were successfully salvaged with surgery; therefore, the ultimate LC rate was 100%. Both the 5- and 10-year freedom from distant metastasis rates were 91%. Three patients developed lung metastases, including 1 patient who experienced GCTB transformation into a high-grade sarcoma. The 5- and 10-year progression-free survival rates were both 78%., Conclusions: Moderate-dose radiotherapy for GCTB provides a long-term LC >80%, justifying its role as an alternative to morbid surgery.

Wierzbicki JM, Henderson JH, Scarborough MT, Bush CH, Reith JD, and Clugston JR
- Abstract
Context: Intramuscular hemangiomas are common in the general population and often present at medical and surgical clinics. Unfortunately, unfamiliarity with these lesions has led to a high percentage of misdiagnoses, inappropriate workup, and unnecessary referrals., Evidence Acquisition: A literature search was performed using Medline, Embase, PubMed, and Cochrane. The relevant articles and referenced sources were reviewed for additional articles that discussed the epidemiology, pathophysiology, investigation, and management of intramuscular hemangiomas. Clinical experience from experts in orthopaedics, musculoskeletal pathology, and musculoskeletal radiology was compared. The selected case studies are shared cases of the authors., Results and Conclusion: The pathophysiology of these lesions is not completely understood, but much can be implied from their underlying vascular nature. Isolated lesions are benign tumors that never metastasize but tend to enlarge and then involute over time. Magnetic resonance imaging is the imaging modality of choice. If a systemic disorder or malignancy is not suspected or has been ruled out, conservative management is the treatment of choice for most intramuscular hemangiomas.

- Abstract
Soft tissue sarcoma is a rare malignancy, with approximately 11,000 cases per year encountered in the United States. It is primarily encountered in adults but can affect patients of any age. There are many histologic subtypes and the malignancy can be low or high grade. Appropriate staging work up includes a physical exam, advanced imaging, and a carefully planned biopsy. This information is then used to guide the discussion of definitive treatment of the tumor which typically involves surgical resection with a negative margin in addition to neoadjuvant or adjuvant external beam radiation. Advances in imaging and radiation therapy have made limb salvage surgery the standard of care, with local control rates greater than 90% in most modern series. Currently, the role of chemotherapy is not well defined and this treatment is typically reserved for patients with metastatic or recurrent disease and for certain histologic subtypes. The goal of this paper is to review the current state of the art in multidisciplinary management of soft tissue sarcoma.

- Abstract
Objectives: The objective of the study was to evaluate our long-term outcomes and prognostic factors for patients treated for localized synovial sarcoma., Methods: We retrospectively reviewed the medical records of 92 patients treated for nonmetastatic synovial sarcoma at the University of Florida from 1967 to 2007. Most patients were treated with limb-sparing surgery and radiation (63%), 27% received surgery alone and 10% received radiation only as definitive treatment. Among patients treated with surgery and radiation, 69% received preoperative radiation and 31% received postoperative radiation., Results: Median follow-up of living patients was 12.5 years. Overall survival rates at 5 and 10 years were 61% and 56%, respectively. Progression-free survival rates were 56% and 53%, respectively. Local control (LC) rates at 5 and 10 years were 90% and 88%, respectively. Freedom from distant metastasis rates were 57% at 5 years and 55% at 10 years. The severe complication (requiring surgery) rate was 13%. Size >5 cm predicted worse overall survival, progression-free survival, and freedom from distant metastasis, but not LC. No other prognostic factor was significant on multivariate analysis., Conclusions: Selectively adding radiotherapy to surgery results in excellent LC for these patients. However, distant metastasis remains the principal factor limiting survival and seems directly related to primary tumor size at presentation.

- Abstract
Background: Treatment of periacetabular sarcomas remains a difficult challenge. Many reconstruction options are fraught with high complication and failure rates. Little is known about patients' functional outcomes, and there have been no studies that examine how these reconstructions affect patients' gait parameters. The purpose of this study is to evaluate gait parameters and functional outcome in patients whom have undergone periacetabular resections with either an ischiofemoral pseudoarthrodesis or soft tissue reconstruction only., Methods: Ten patients with sarcoma of the periacetabular region were identified from our database. Functional outcome was assessed using the Musculoskeletal Tumor Society Scores (MSTS) and Toronto extremity salvage score (TESS) scoring systems. Gait analysis was performed on all subjects., Results: Patients in both surgical groups had average functional scores. All patients were ambulatory. Cadence and velocity in the surgical group were significantly slower than the control group, however, the remainder of the gait parameters examined were similar to controls., Conclusion: Patients who underwent minimal reconstruction following periacetabular resections demonstrated average functional scores, comparable to those undergoing more extensive reconstructions. With the exception of speed, gait parameters were not significantly different than controls. Complication rates were low. Pseudoarthrodesis or even no bone reconstruction following periacetabular resection is reasonable and functional options for many of these patients., (Copyright © 2012 Wiley Periodicals, Inc.)

- Abstract
Purpose: To review long-term outcomes following postoperative radiotherapy (RT) for extremity soft tissue sarcoma (STS) and identify variables affecting the therapeutic ratio., Methods and Materials: Between 1970 and 2008, 173 patients with localized extremity STS were treated with postoperative radiation. No patients received prior irradiation. Sixteen percent of tumors had recurred after initial surgery alone; 89% of tumors were high grade. The median patient age was 57 years (range, 18-86 years). Sixty-one percent underwent >1 surgery before RT in an attempt to achieve wide negative margins. Final margin status was negative in 70% and marginal or microscopically positive in 30%. The median time between final surgery and start of RT was 40 days. The median RT dose was 65 Gy (range, 49-74 Gy). The median follow-up for all patients was 10.4 years and 13.2 years among survivors., Results: At 10 years, local control (LC), cause-specific survival (CSS), and overall survival (OS) rates were 87%, 80%, and 70%, respectively, with 89% of local failures occurring within 3 years after treatment. On multivariate analysis, age >55 years (82% vs 93%, P<.05) and recurrent presentation (67% vs 91%, P<.05) were associated with inferior 10-year LC. The LC according to final margin status was 90% for wide negative margins vs 79% for marginal/microscopically positive margins (P=.08). Age>55 years and local recurrence were associated with inferior CSS and OS on multivariate analysis. Twelve percent of patients experienced grade 3+ toxicity; 12 of these occurred in patients with tumors of the proximal lower extremity, with the most common toxicity of pathologic fracture occurring in 6.3%., Conclusions: This large single-institution series confirms that postoperative RT for STS of the extremities provides good long-term disease control with acceptable toxicity. Our experience supports recurrent presentation and older age as adverse prognostic factors for LC., (Copyright © 2012 Elsevier Inc. All rights reserved.)

- Abstract
Background: Marginal excision of soft tissue sarcoma (STS), defined as resection through the tumor pseudocapsule or surrounding reactive tissue, increases the likelihood of local recurrence and necessitates re-excision or postoperative radiation. However, its impact after preoperative radiation therapy (RT) remains unclear. This study therefore investigated the significance of marginal margins in patients treated with preoperative RT for extremity STS, reporting long-term local control and limb preservation endpoints., Methods: The records of 317 adults at the University of Florida with nonmetastatic extremity STS treated from 1980 to 2008 with preoperative RT as part of a limb conservation strategy were reviewed. The median follow-up was 4.7 years (8.3 years for living patients). The median tumor size was 10 cm (range, 2-36 cm), and 86% were high grade. The median RT dose was 50.4 Gy (range, 12.5-57.6 Gy). Margins were classified as wide/radical (n = 105), marginal (n = 179), contaminated (n = 15), positive (n = 17), or unknown (n = 1). Endpoints were local control (LC), amputation-free survival (AFS), cause-specific survival (CSS), and overall survival (OS)., Results: Five-year CSS and OS rates were 62% and 59%, respectively. Five-year LC and AFS was 93% and 89%, respectively. AFS by margin status was 64%, 83%, 97%, and 92% for positive, contaminated, marginal, and wide/radical margins, respectively (P<.005). Marginal excision following preoperative RT resulted in equivalent LC and AFS compared with wide/radical margins., Conclusions: Marginal resection after preoperative RT does not compromise LC or AFS in extremity STS. This finding may be related to radiosterilization of tumor cells within the reactive zone following preoperative RT., (Copyright © 2011 American Cancer Society.)

Introduction: Chondrosarcoma is well-known to be primarily resistant to conventional radiation and chemotherapy., Case Presentation: We present the case of a 32-year-old Caucasian man with clear cell chondrosarcoma who presented with symptomatic recurrence in his pelvis and metastases to his skull and lungs. Our patient underwent systemic therapy with sunitinib and then consolidation with proton beam radiation to his symptomatic site. He achieved complete symptomatic relief with a significantly improved performance status and had an almost complete and durable metabolic response on fluorine-18-fluorodeoxyglucose positron emission tomography., Conclusions: Our findings have important clinical implications and suggest novel clinical trials for this difficult to treat disease.

- Abstract
Chest CT scans are often used to monitor patients after excision of a sarcoma. Although sensitive, CT scans are more expensive than chest radiographs and are associated with possible health risks from a higher radiation dose. We hypothesized that a program based upon limited CT scans in lower-grade sarcoma could be efficacious and less expensive. We retrospectively assigned patients to a high-risk or low-risk hypothetical protocol. Eighty-three low- or intermediate-grade soft tissue sarcomas met our inclusion criteria. Eight patients had pulmonary metastasis. A protocol based on selective CT scans for high-risk patients would have identified seven out of eight lesions. The incremental cost-effectiveness ratio for routine CT scans was $731,400. A program based upon selective CT scans for higher-risk patients is accurate, spares unnecessary radiation to many patients, and is less expensive.

- Abstract
Several studies have identified cyclooxygenase-2 (COX-2) expression in a variety of sarcomas, including rhabdomyosarcoma, osteosarcoma and chondrosarcoma. Although overexpression of COX-2 has been associated with poor prognosis and decreased survival in chondrosarcoma and osteosarcoma, no relationship between COX-2 expression and patient outcome has been demonstrated in rhabdomyosarcoma or adult soft tissue sarcomas. Little is known concerning the expression of COX-2 in synovial sarcoma. Therefore, the aim of this study was to examine the expression of COX-2 in synovial sarcoma and if shown, to identify any association with tumor stage and oncologic outcome. Paraffin-embedded specimens from 27 patients with synovial sarcoma who were treated with surgical resection or biopsy were obtained. Specimens were evaluated for the degree of COX-2 expression after immunohistochemical staining. Specimens were assigned an immunoreactivity score (IS) based on the percent positivity of the specimen. A retrospective chart analysis was performed to determine the clinical stage at presentation, incidence of local recurrence, presence of metastatic disease and overall survival. Statistical analysis was then performed to determine whether there was a significant relationship between IS and stage at presentation or patient outcomes. COX-2 expression was detected in 18 of 27 (66.67%) of the pathological specimens. There was a statistically significant relationship between COX-2 expression and patient clinical stage at presentation; however, we were unable to identify a significant relationship between IS and patient survival. We also found no significant relationship between IS and development of metastases or local recurrence. COX-2 was expressed to some degree in 67% of the tumor specimens. There was a significant relationship between IS and patient stage at presentation, but no significant relationship between COX-2 expression and clinical outcome could be identified. The fact that these tumors do express COX-2, however, suggests the potential for an additional target for more effective therapy.

- Abstract
Background: To report long-term outcomes following radiotherapy for desmoid tumors in children and young adults and identify variables impacting local-regional control and treatment complications., Procedure: From 1978 to 2008, 30 patients <30 years old were treated with radiotherapy for a pathologically confirmed desmoid tumor. The median age at radiotherapy was 23.7 years old (range, 10.3-29.9). Fifteen patients underwent definitive radiotherapy, 14 received radiotherapy after gross total resection, and 1 received preoperative radiotherapy. Sixteen patients received 1.8 Gy once daily and 14 received 1.2 Gy twice daily. Variables analyzed for prognostic value included gender, age at diagnosis, primary or recurrent presentation, age at radiotherapy, tumor site, tumor size, extent of resection, fractionation schedule, and radiotherapy dose., Results: The actuarial 15-year overall survival and local-regional control rates were 96% and 55%, respectively. Local-regional control in patients <18 years old at the time of radiotherapy was 20% versus 63% in those 18-30 years old (P = 0.08). Local-regional control rates for tumors receiving ≥ 55 Gy and < 55 Gy were 79% and 30%, respectively (P = 0.02). No other factors had a statistically significant association with local-regional control by univariate analysis. Twelve of 30 patients experienced grade 3-4 complications, including pathologic fractures, impaired range of motion, pain, and in-field skin cancers., Conclusions: The role of radiotherapy in managing young patients with desmoid tumors remains unclear. Younger patient age is associated with inferior local-regional control following RT. In children and young adults, doses ≥55 Gy were associated with improved tumor control, but also lead to increased risk of complications., (Copyright © 2010 Wiley-Liss, Inc.)

- Abstract
Purpose: To review the 40-year University of Florida experience treating Ewing sarcoma family of tumors of the chest wall., Methods and Materials: Thirty-nine patients were treated from 1966 to 2006. Of the patients, 22 were treated with radiotherapy (RT) alone, and 17 patients were treated with surgery with or without RT. Of 9 patients with metastatic disease, 8 were treated with RT alone. The risk profiles of each group were otherwise similar. The median age was 16.6 years, and the most frequent primary site was the rib (n=17). The median potential follow-up was 19.2 years., Results: The 5-year actuarial overall survival (OS), cause-specific survival (CSS), and local control (LC) rates were 34%, 34%, and 72%, respectively. For the nonmetastatic subset (n=30), the 5-year OS, CSS, and LC rates were 44%, 44%, and 79%, respectively. LC was not statistically significantly different between patients treated with RT alone (61%) vs. surgery+RT (75%). None of the 4 patients treated with surgery alone experienced local failure. No patient or treatment variable was significantly associated with local failure. Of the patients, 26% experienced Common Toxicity Criteria (CTC) Grade 3+ toxicity, including 2 pulmonary deaths. Modern intensive systemic therapy helped increase the 5-year CSS from 7% to 49% in patients treated after 1984 (p=0.03)., Conclusions: This is the largest single-institution series describing the treatment of chest wall Ewing tumors. Despite improvements in survival, obtaining local control is challenging and often accompanied by morbidity. Effort should be focused on identifying tumors amenable to combined-modality local therapy and to improving RT techniques., (Copyright © 2011 Elsevier Inc. All rights reserved.)

- Abstract
Purpose: To evaluate the prognostic factors, outcomes, and complications in patients aged ≤30 years with resectable nonrhabdomyosarcoma soft-tissue sarcoma treated at the University of Florida with radiotherapy (RT) during a 34-year period., Methods and Materials: A total of 95 pediatric or young adult patients with nonrhabdomyosarcoma soft-tissue sarcoma were treated with curative intent with surgery and RT at the University of Florida between 1973 and 2007. The most common histologic tumor subtypes were synovial sarcoma in 22 patients, malignant fibrous histiocytoma in 19, and malignant peripheral nerve sheath tumor in 11 patients. The mean age at RT was 22 years (range, 6-30). Of the 95 patients, 73 had high-grade tumors; 45 had undergone preoperative RT and 50 postoperative RT. The prognostic factors for survival, local recurrence, and distant recurrence were analyzed., Results: The median follow-up was 7.2 years (range, 0.4-30.5). The actuarial 5-year local control rate was 88%. A microscopically negative margin was associated with superior local control. Although 83% of local recurrence cases initially developed in the absence of metastases, all patients with local failure ultimately died of their disease. The actuarial estimate of 5-year overall survival and disease-free survival was 65% and 63%, respectively. Of all the deaths, 92% were disease related. An early American Joint Committee on Cancer stage, tumor<8 cm, and the absence of neurovascular invasion were associated with superior disease-free survival. The National Cancer Institute Common Toxicity Criteria, version 3, Grade 3-4 treatment complication rate was 9%. No secondary malignancies were observed., Conclusion: In the present large single-institution study, we found positive margins and locally advanced features to be poor prognostic factors for both local progression and survival. The results from the present study have helped to characterize the therapeutic ratio of RT in pediatric and young adult sarcoma patients and have provided a basis for identifying high-risk patients for whom treatment intensification might be justified., (Copyright © 2011 Elsevier Inc.

- Abstract
Background: Few published articles describe outcomes following definitive radiation for unresectable pediatric and young adult nonrhabdomyosarcoma soft tissue sarcoma (NRSTS). The purpose of this study is to evaluate the prognostic factors, outcomes, and complications in patients age 30 years or younger with NRSTS treated at the University of Florida from 1973 to 2002., Procedure: Nineteen pediatric and young adult patients with NRSTS were treated with radiotherapy after biopsy. Thirteen patients had high-grade tumors. The median age at radiotherapy was 19.6 years; the median dose was 55.2 Gy. Twelve patients received chemotherapy. Prognostic factors for local recurrence, distant metastases, and survival were analyzed., Results: Median follow-up was 2.6 years. The 5-year local-control rate was 40%. Nine out of 13 local failures occurred in the absence of metastatic disease. All patients with local failures died of their cancer, and 8 patients died without evidence of distant metastases. There was a trend toward improved local control with low/intermediate-grade tumors. Freedom from distant metastases at 5 years was 68%. Fourteen patients died of their disease. The 5-year overall survival was 37%. There was one grade 4 complication based on NCI Common Terminology Criteria for Adverse Events version 3., Conclusion: Young patients with unresectable NRSTS have a poor outcome thereby justifying current study efforts focused on treatment intensification. By demonstrating that all patients with local recurrence died of disease and more than half of these deaths occurred in the absence of distant spread, these results suggests that improved means of local control may translate into improvement in survival., (Copyright © 2011 Wiley-Liss, Inc.)

- Abstract
Metastatic disease to long bones is common and often requires stabilization to treat or prevent fracture. Intramedullary fixation is used in many metaphyseal and diaphyseal lesions. The goal of this study was to investigate the causes of and risk factors for reconstructive failure in intramedullary fixation of metastatic disease. We performed a retrospective review of 112 consecutive reconstructions for metastatic disease treated with an isolated intramedullary nail. There were 81 reconstructions in the femur, 25 in the humerus, and 6 in the tibia. All included patients were followed until death or reconstructive failure. All surviving patients had a minimum 2-year follow-up.Ten failures required construct revision. Median time to revision was 17.9 months (range, 3-93 months). The causes of failure included surgeon error, tumor progression, nonunion, and hardware failure. Patients with short survival times (P<.001) or a diagnosis of lung cancer (P=.029) were unlikely to fail. Revision was required in 6 solitary lesions (P=.012), 3 cases of lymphoma (P=.002), 3 cases of progressive renal cell carcinoma (P=.040), and 2 radiation-associated fractures (P=.007).Intramedullary stabilization is a successful operation for appropriate lesions. Failures may be minimized with proper implant selection and surgical technique, resection or curettage of renal cell carcinoma, avoidance of radiation-associated fractures, and overestimating patient survival., (Copyright 2011, SLACK Incorporated.)

- Abstract
Background: Complications are frequent with osteoarticular allografts, and their long-term survivorship in the distal femur is unclear. Thus, the benefits of osteoarticular allografting remain controversial., Questions/purposes: We therefore determined the frequency of complications in osteoarticular allografts of the distal femur relative to their potential long-term survival., Methods: We retrospectively reviewed 26 patients who had osteoarticular allograft reconstruction of the distal femur after resection of a malignant or aggressive benign tumor of bone. The minimum followup was 15 months (average, 156 months; range, 15-283 months) for all patients and 98 months (average, 191 months; range, 98-283 months) for the surviving patients., Results: At last followup, 16 of the 26 original allografts were still in place. The overall 5-year and 10-year allograft survival rates were 69% and 63%, respectively. The 5-year and 10-year survival rates of the joint surface were 79% and 65%, respectively. Eleven patients retained their original osteoarticular allograft without a resurfacing procedure, and nine had been converted to allograft-prosthetic composites. Five patients were converted to megaprostheses and one had an amputation for local recurrence. At last followup, 25 of 26 patients retained a functional limb., Conclusions: Osteoarticular allograft reconstructions of the distal femur can provide long term survival and restore function but the risk of complications and their physical and monetary costs for patients are not trivial. Lacking the benefit of improved soft tissue attachments inherent in other anatomic sites, we believe this option is most appropriate for restoring bone stock in young patients with expectations of long-term survival.

- Abstract
Purpose: To perform a review of the 40-year University of Florida experience treating spinal and paraspinal Ewing tumors., Patients and Methods: A total of 27 patients were treated between 1965 and 2007. For local management, 21 patients were treated with radiotherapy (RT) alone and 6 with surgery plus RT. All patients with metastatic disease were treated with RT alone. The risk profiles of each group were otherwise similar. The median age was 17 years, and the most frequent subsite was the sacral spine (n = 9). The median potential follow-up was 16 years., Results: The 5-year actuarial overall survival, cause-specific survival, and local control rate was 62%, 62%, and 90%, respectively. For the nonmetastatic subset (n = 22), the 5-year overall survival, cause-specific survival, and local control rate was 71%, 71%, and 89%, respectively. The local control rate was 84% for patients treated with RT alone vs. 100% for those treated with surgery plus RT. Patients who were >14 years old and those who were treated with intensive therapy demonstrated superior local control. Of 9 patients in our series with Frankel C or greater neurologic deficits at presentation, 7 experienced a full recovery with treatment. Of the 27 patients, 37% experienced Common Toxicity Criteria Grade 3 or greater toxicity, including 2 deaths from sepsis., Conclusion: Aggressive management of spinal and paraspinal Ewing tumors with RT with or without surgery results in high toxicity but excellent local control and neurologic outcomes. Efforts should be focused on identifying disease amenable to combined modality local therapy and improving RT techniques.

- Abstract
Soft-tissue sarcoma (STS) is a histopathologically diverse group of tumors accounting for approximately 10,000 new malignancies in the US each year. The proximal lower extremity is the most common site for STS, accounting for approximately one-third of all cases. Coordinated multimodality management in the form of surgery and radiation is often critical to local control, limb preservation, and functional outcome. Based on a review of currently available Medline literature and professional experience, this paper provides an overview of the treatment of STS of the lower extremity with a particular focus on the modern role of radiotherapy.

- Abstract
Objective: The purpose of our study was to retrospectively examine the efficacy of intralesional injection of 32P chromic phosphate, a beta-emitting colloidal radiopharmaceutical, in the treatment of aneurysmal bone cysts of the axial skeleton. Five patients with large aneurysmal bone cysts were managed with injection of 32P chromic phosphate into their tumors under CT guidance. With only a single minor complication, all lesions were observed to ossify on follow-up CT, with an average follow up of 2 years., Conclusion: CT-guided injection of axial aneurysmal bone cysts with 32P chromic phosphate leads to excellent local lesion control. In addition, the morbidity associated with this procedure is lower than that associated with surgical or other nonsurgical treatments.
