Pelvis reconstruction by proximal femur upshifting and total hip arthroplasty after radical resection of an adolescent patient pelvic Ewing's sarcoma, a case report, and literature review. Int J Surg Case Rep 2023; 106:108146. [PMID: 37068459 PMCID: PMC10130465 DOI: 10.1016/j.ijscr.2023.108146] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Revised: 03/27/2023] [Accepted: 03/29/2023] [Indexed: 04/19/2023] Open
Abstract
INTRODUCTION AND IMPORTANCE Pelvis reconstruction after tumor resection poses a challenge, especially in younger patients where preserving the patient's function and mobility is paramount. CASE PRESENTATION A 16 years old female presented in March 2019 with vague right iliac area pain, diagnosed as pelvic Ewing's sarcoma after imaging studies (MRI and MSCT scan) and obtaining an incisional biopsy. After initial chemotherapy cycles, the tumor decreased in size, and surgical intervention in two stages was performed. The first stage was in October 2019 and consisted of pelvic resection type I and II according to Enneking and Dunham classification, proximal femur upshifting to compensate for the pelvic bone defect, and a cement spacer to fill the space of the resected proximal femur. The second stage was performed after two months and consisted of implanting a total hip arthroplasty using Megaprostheses and a cementless dual mobility acetabular cup. No local recurrence or distant metastases were detected during follow-ups. At the final follow up after 36 months, the patient showed acceptable functional outcomes (HHS score 83, and MSTS score 23 (76.7 %) points), and the radiographs showed proper implant positioning and stability. CLINICAL DISCUSSION Treating pelvic Ewing's sarcoma requires a multidisciplinary team. After surgical resection, the pelvic reconstruction options include using allografts or autografts, femur upshifting, and hemipelvis prostheses, which should be chosen considering patients and tumor characteristics as well as surgical team efficiency. CONCLUSION Reconstructing the pelvic defect after bone tumor resection by proximal femoral upshifting is a valid biological option with acceptable outcomes.

Impact of local treatment modality on overall- and disease-specific survival for nonmetastatic pelvic and sacral Ewing sarcoma. J Surg Oncol 2022; 126:577-587. [PMID: 35585834 DOI: 10.1002/jso.26922] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Revised: 04/23/2022] [Accepted: 05/02/2022] [Indexed: 12/12/2022]
Abstract
PURPOSE The ideal local treatment modality for pelvic and sacral Ewing sarcoma (EWS) is controversial. METHODS We present the data from the American College of Surgeon's National Cancer Database (NCDB) and the National Cancer Institute's Surveillance, Epidemiology and End Result (SEER) database to investigate the impact of local treatment modalities on survival for nonmetastatic pelvic and sacral Ewing sarcoma. Local treatment includes "surgery," "radiation," and a combination of "surgery and radiation." RESULTS A total of 235 cases from SEER and 285 cases from NCDB were analyzed. Patients with "localized" stage (intraosseous) in the SEER database did not show any statistically significant difference in the disease-specific survival (DSS) for any of the local treatment modalities. Similar findings were observed for overall survival among patients with American Joint Committee on Cancer (AJCC) stage II and III in the NCDB database. However, patients with nonmetastatic disease, particularly regional disease (extraosseous), showed improved DSS with surgery only, in the SEER. CONCLUSION We found similar levels of efficacy for different treatment modalities for patients with intraosseous and AJCC II and III pelvic and sacral EWS. "Radiotherapy" is the most common local treatment modality employed in the United States. A prospective, randomized controlled trial with a direct head-to-head comparison is needed for a definitive conclusion.

J Orthop Translat 2021; 28:108-117. [PMID: 33868923 PMCID: PMC8022806 DOI: 10.1016/j.jot.2020.12.006] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2020] [Revised: 12/15/2020] [Accepted: 12/22/2020] [Indexed: 11/26/2022] Open
Abstract
Background Surgery for Ewing sarcoma involving acetabulum in children is challenging. Considering the intrinsic structure of immature pelvis, trans-acetabular osteotomy through triradiate cartilage might be applied. The study was to describe the surgical technique and function outcomes of trans-acetabular osteotomy through triradiate cartilage and reconstruction with customized, 3D-printed prosthesis. Methods Two children with periacetabular ES were admitted to our hospital. The pre-operative imaging showed the triradiate cartilage was not penetrated or wholly affected by tumor. After neoadjuvant chemotherapy, the tumor was excised by trans-acetabular osteotomy basing on “triradiate cartilage strategy” and the acetabulum was reconstructed with the customized, 3D-printed prosthesis. The prosthesis was designed in Mimics software basing on the images from CT, optimized by topology technique, and examined in FE model. After implantation, the oncological and functional outcomes were evaluated with radiography, CT, and MSTS score. Results The operation time and intra-operative blood loss in these two children were 3.5h, 2.5h and 300 ml, 600 ml, respectively. The postoperative specimen showed the tumor was en bloc removed with safe margin. In the latest follow-up (48 months and 24 months), both patients were free of disease and had satisfactory function according to MSTS score. The radiography indicated the prosthesis fit the defect well without loosening. Conclusion The customized, 3D-printed prosthesis could provide optimal reconstruction of pelvic ring and satisfactory hip function after trans-acetabular osteotomy in children. The translational potential of this article This study provides promising results of implantation of customized 3D printing prosthesis in children’s pelvic sarcoma, which may bring a new design method for orthopaedic implants.

Pelvic Ewing sarcoma: a retrospective outcome analysis of 104 patients who underwent pelvic tumor resection at a single supra-regional center. J Orthop Surg Res 2020; 15:534. [PMID: 33198775 PMCID: PMC7667797 DOI: 10.1186/s13018-020-02028-3] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Accepted: 10/20/2020] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Local treatment in pelvic Ewing sarcoma (ES) consists of operation, radiation therapy, or a combination of both. Reported outcomes vary depending on the treatment modality performed. It is the objective of this study to analyze surgical outcome and complications as well as oncological outcome and complications of chemo- and radiation therapy in this patient cohort and evaluate prognostic factors. METHODS Retrospective review of 104 patients who underwent tumor resection for pelvic ES from 1988 to 2014. RESULTS All patients underwent pelvic resection and radiation therapy was administered in 77.9%. Margins were clear in 94.2%. The response to chemotherapy was good in 78.8%. Local recurrence occurred in 7.7%. The presence of distant metastases at the time of operation was the most important negative predictor for overall survival (p = 0.003). The cumulative 5- and 10-year survival rates were 82.7% and 80.1% for non-metastasized and 61.4% and 41.6% for metastasized pelvic ES at operation. In the presence of a single-distant metastatic site at operation compared to multiple metastatic sites, the cumulative survival rates were 64.3% versus 50% at five and 50.7% versus 16.7% at 10 years. CONCLUSIONS A combined treatment approach of tumor resection and radiation therapy leads to a local control and overall survival rates comparable with those of extremity locations in this study's patient cohort with localized pelvic ES. Therefore, surgical tumor resection (combined with (neo-)adjuvant radiation therapy) in non-metastatic pelvic ES seems feasible. In metastatic patients, however, the significance of tumor resection as a part of local treatment remains less certain and improved outcomes of combined local treatment approaches need to be weighed against these patients' prognosis and quality of life.

Abstract
Clinical management of adolescents and young adults with bone and soft tissue sarcomas is quite challenging, mainly because of different chemotherapy approaches adopted by pediatric and adult oncologists and tumor-associated factors related to this peculiar age group. Overcoming these barriers is essential for adolescent and young adult patients, whose survival and long-term physical effects are worse than their pediatric counterparts. Nowadays, constant efforts from international collaborations between pediatric and adult oncologists of sarcoma groups have optioned in converging toward a common therapeutic strategy, while improving quality of treatment, as well as research advances dedicated to this at-risk age group of patients with sarcomas.

Abstract
PURPOSE The purpose of this study was to clarify which local treatment is oncologically and functionally effective in pelvic Ewing sarcoma (ES). METHODS A consecutive series of patients who underwent pelvic resections and acetabular reconstructions after chemotherapy between 1986 and 2016 at a supra-regional center were evaluated. RESULTS The cohort consisted of 35 patients. The 5-year overall survival (OS) and local recurrence-free survival (LRFS) was 61% and 72%, respectively. Preoperative radiotherapy (RT) and surgery provided an excellent/good histological response in 92% and achieved significantly better OS (5 years, 64%) and LRFS (5 years, 100%) than surgery alone or surgery with postoperative RT. The Musculoskeletal Tumor Society functional scores were significantly better in patients with hip transposition than those with structural reconstructions (74% vs 57%; P = .031) using custom-made prostheses, irradiated autografts, and ice-cream cone prostheses. These scores were significantly lower if patients had deep infection (P = .035), which was the most common complication (28%) in structural reconstructions but did not occur in hip transposition even when performed after preoperative RT. CONCLUSION Acetabular reconstruction with hip transposition resulted in no deep infection and superior function in patients with pelvic ES even when combined with preoperative RT, which improved tumor necrosis and rate of local control and survival.

Abstract
Introduction: Pelvic sarcomas may present with vague symptoms. The aim of this study was to examine the characteristics and clinical presentations of different types of pelvic sarcoma in children. Methods: This is a retrospective cohort study of patients up to 21 years of age with the diagnosis of pelvic sarcoma between January 2000 and June 2013. Data on demographics, tumor type and location, and clinical presentation were collected from the medical records. Results: A total of 59 patients [37 males (62.7%) and 22 females (37.3%)] were examined in this study. Mean age at presentation was 11.3 ± 5 years (range 0.8–21 years). Thirty-six patients had Ewing sarcoma (61%), 9 osteosarcoma (6.8%), 4 undifferentiated sarcoma (6.8%), 2 (3.4%) rhabdomyosarcoma, 2 synovial cell sarcoma, and one (1.7%) of each fibrosarcoma, dermatofibrosarcoma, fibromyxoid sarcoma, chondrosarcoma, chordoma, and epithelioid sarcoma. Pain at presentation was reported in 41 patients, 13 mass, 8 limping, and 5 neurologic symptoms. Most of the bony tumors were painful (77%), while most of the soft tissue tumors were painless (70%). Nine patients presented with constitutional symptoms. Most patients presented within 4–12 months from symptoms beginning. Twenty-one patients (35.6%) presented with metastases (14 Ewing sarcoma, 6 osteosarcoma, and 1 synovial cell sarcoma). Pelvic radiographs showed lytic lesion in 11 patients, 4 sclerotic lesions, 6 mixed lesion, 6 had only soft tissue mass, 1 radiograph showed osteopenia, and 2 radiographs were reported normal. Conclusion: Ewing sarcoma was the most common pelvic sarcoma tumor in children. In most cases, pelvic sarcoma in children presented with pain mimicking other benign conditions. Some patients presented with metastatic disease with no prognostic clinical or radiographical signs or symptoms. Pelvic sarcoma should be considered a differential diagnosis as part of children work up.

Abstract
The present study describes a novel surgical strategy used to treat immature pelvic Ewing's sarcoma (ES), one made possible owing to the intrinsic structure of the skeletally immature pelvis. A total of 12 children and adolescents with open triradiate cartilage received limb-salvage surgeries following a diagnosis of pelvic ES. In total, 3 patients with iliac lesions (2 lesions with extension into the sacrum) received surgical tumor excisions and allograft reconstructions. Another 8 patients with periacetabular lesions received trans-acetabular osteotomies and allograft reconstructions. No reconstruction was performed on 1 patient following excision of a pubic lesion. The median follow-up time was 39 months. At the time of the final follow-up appointment, 9 patients exhibited no evidence of disease, 2 patients had slow progressive pulmonary metastasis, 1 patient exhibited local recurrence of the disease and 1 patient had succumbed to the disease 24 months after surgery. Complications included issues with wound healing in 1 patient, a discrepancy in leg length in another and a screw loosening in a further patient. The patients had a mean Musculoskeletal Tumor Society score of 26 points and a mean International Society of Limb Salvage radiographic score of 90.1%. The proposed surgical strategy for children and adolescents with pelvic ES in the present study could provide a feasible solution for acetabulum salvage and local tumor control.

Abstract
BACKGROUND The primary purpose of this retrospective study was to report on a consecutive series of 102 patients with diabetes mellitus (DM) who underwent transtibial amputation (TTA) for chronic infections and nonreconstructable lower extremity deformities. A secondary aim was to compare the outcomes of TTA patients with end-stage renal disease on dialysis (ESRD) to patients without ESRD, and to identify risk factors for mortality after TTA. METHODS This cohort involved a consecutive series of patients who were treated by a single surgeon. The TTA patients were divided into 2 groups for analysis. The study group included those patients with ESRD who underwent TTA, and the control group included those patients who did not have ESRD. RESULTS At the time of final follow-up, 64 of 102 patients were ambulatory with a prosthesis. There was a significant improvement in ambulatory status after amputation (preoperatively 45.1%, postoperatively 62.7%, P = .02). Wound healing complications (infection and/or dehiscence) occurred in 31 of 102 patients and led to a transfemoral amputation in 4 patients. After TTA patients with ESRD were significantly more likely to die (52.4% vs. 23.5%, p <0.05) and significantly less like to ambulate (42.9% vs. 67.9%, p <0.05) than patients without ESRD. Contralateral foot problems after the TTA occurred in 33 of 97 patients and resulted in 10 patients undergoing a contralateral transtibial amputation. Excluding patients with bilateral amputations (5 prior to and 10 after the index amputation), 64 of 87 patients with successful unilateral transtibial amputations were able to ambulate with a prosthesis. Thirty of 102 patients (29.4%) died during the follow-up period, and 6 of these deaths occurred during the perioperative period (within 30 days of surgery). There were no significant differences between the 2 groups with regard to the use of staged TTA, need for transfemoral amputation, or wound healing problems at the amputation site. Patients who were unable to walk postoperatively had a calculated 5-year survival rate of 30.1%, whereas those who were ambulatory had a 5-year survival rate of 68.8%. Cox proportional hazards model demonstrated a 62% reduced risk of mortality in patients who were able to ambulate after LEA compared with those patients who were not able to ambulate. CONCLUSION TTA in patients with diabetes was associated with substantial morbidity and mortality. Risk factors that were significantly associated with an increased rate of mortality were the presence of ESRD, age ≥56 years, and inability to ambulate postoperatively. LEVEL OF EVIDENCE Level III, retrospective case controlled study.

Abstract
BACKGROUND The aim of this study was to evaluate the accuracy of supra-acetabular pelvic tumor resections in human, full-body cadavers and under realistic operation room conditions with the help of a navigation system and K-wires as guidance for the oscillating saw. METHODS Seven hemipelvises from fresh, human, male, full-body cadavers were used. A preoperative and a postoperative CT was performed. Under control of the navigation system K-wires were inserted and served as guidance for the oscillating saw to reduce the error by vibration and jerking movements. The accuracy of the computer aided resections was compared with the accuracy of freehand resections in customized 3D printed pelvises with geometries identical to the cadavers used. RESULTS The mean deviation of the navigated osteotomies was 1.9 mm (standard deviation 1.0 mm) significantly (P < 0.001) lower than the mean deviation of freehand osteotomies at 9.2 mm (standard deviation 3.7 mm). CONCLUSION Navigated K-wires for supra-acetabular osteotomies allow significantly higher accuracy than freehand procedures under simulated operation room conditions.

Abstract
BACKGROUND Pelvic Ewing sarcoma (ES) has poorer outcomes than extremity-based lesions and the method of local control is controversial. METHODS A retrospective review was performed of 40 primary pelvic or sacral ES treated by a single surgeon. All received modern chemotherapy and those that received radiation were treated with modern dosages. RESULTS Fifty-five percent were disease-free at latest follow-up (median, 83.1 mos). Sixty-one percent had ≥ 99% necrosis, which was associated with 65% disease-free survival. Larger size (P = 0.016) and the absence of metastatic disease (P = 0.005) was predictive of survival. Eighty-three percent of relapsed patients were DOD. Half of patients who received surgery alone or RT alone have NED while 57% of those who received S/RT have NED. Complication rates were 69% (S/RT), 75% (surgery alone), 10% (RT alone). Functional outcomes were similar. CONCLUSION Primary pelvic ES is localized at presentation in 50% and the absence of metastases is the strongest predictor for survival. Chemotherapy is key, but excellent histologic response is neither a guarantee nor a necessity for survival. More than one-third die despite an excellent histologic response and at least one-third with lung metastases survive. With chemotherapy, radiation, and surgery, reasonable control of disease can be achieved. LEVEL OF EVIDENCE III Case-control or retrospective cohort study.

Abstract
Background. Ewing sarcoma family of tumors (ESFT) are rare but deadly cancers of unknown etiology. Few risk factors have been identified. This study was undertaken to ascertain any possible association between exposure to therapeutic drugs and ESFT. Methods. This is a retrospective, descriptive study. A query of the FDA Adverse Event Reporting System (FAERS) was conducted for all reports of ESFT, January 1, 1998, through December 31, 2013. Report narratives were individually reviewed for patient characteristics, underlying conditions and drug exposures. Results. Over 16 years, 134 ESFT reports were identified, including 25 cases of ESFT following therapeutic drugs and biologics including immunosuppressive agents and hormones. Many cases were confounded by concomitant medications and other therapies. Conclusions. This study provides a closer look at medication use and underlying disorders in patients who later developed ESFT. While this study was not designed to demonstrate any clear causative association between ESFT and prior use of a single product or drug class, many drugs were used to treat immune-related disease and growth or hormonal disturbances. Further studies may be warranted to better understand possible immune or neuroendocrine abnormalities or exposure to specific classes of drugs that may predispose to the later development of ESFT.

Abstract
Ewing's sarcoma of bone is a primary bone sarcoma found predominantly in patients during their second decade of life. It is a high-grade aggressive small round blue cell tumor that is part of the Ewing's family of tumors. Its exact eitiology is unknown but it commonly demonstrates reproducible staining of CD99 and translocations of the EWS gene. Historically, this diagnosis was associated with near certain metastasis and subsequent mortality. However, current management consists of extensive chemotherapy in addition to local control with surgical resection and/or radiation. As a result, survival has improved to the 55-75% range in those patients who present without known metastases. Current research aims to continue this improvement by looking further into the associated gene abnormalities and possibly targeted therapies.

Abstract
Osteosarcoma, Ewing sarcoma, and rhabdomyosarcoma are the most common malignant musculoskeletal tumors in children and adolescents. Today, most patients can be cured. Numerous factors have contributed to improved outcome for these patients over the past several decades. These include multidisciplinary care involving oncologists, radiation oncologists, surgeons, pathologists, and radiologists and enrollment of patients in clinical trials. Better understanding of molecular mechanisms of disease have resulted in studies using molecular targets in addition to standard chemotherapeutic agents, which hopefully will lead to better outcomes in the future. Moreover, new orthopedic techniques and devices as well as new technologies in radiation oncology hold promise for better local control of primary tumors and the potential for fewer late adverse effects. Despite this progress, patients must undergo lifelong follow-up for possible late effects of intense chemotherapy and radiation therapy. We review the diagnosis, prognosis, staging, multidisciplinary therapy, new directions in therapy, and long-term complications of treatment for these tumors. For this review, we searched MEDLINE using the terms rhabdomyosarcoma, osteosarcoma, Ewing sarcoma, biology, and humans and limited the search to articles from 2000 to September 2011. Additional references found in these articles were utilized as appropriate, as well as references from the background information in current therapeutic studies of the Children's Oncology Group. The same database and time frame were searched for articles written by leading authorities in the field.

Should Aggressive Surgical Local Control Be Attempted in All Patients with Metastatic or Pelvic Ewing's Sarcoma? Sarcoma 2012; 2012:953602.

Abstract
In previous reports, patients with Ewing's sarcoma received radiation therapy (XRT) for definitive local control because metastatic disease and pelvic location were thought to preclude aggressive local treatment. We sought to determine if single-site metastatic disease should be treated differently from multicentric-metastatic disease. We also wanted to reinvestigate the impact of XRT, pelvic location, and local recurrence on outcomes. Our results demonstrated a significant difference in overall survival (OS) between patients with either localized disease or a single-metastatic site and patients with multicentric-metastatic disease (P = 0.004). Local control was also found to be an independent predictor of outcomes as demonstrated by a significant difference in OS between those with and without local recurrence (P = 0.001). Axial and pelvic location did not predict a decreased OS. Based on these results, we concluded that pelvic location and the diagnosis of metastatic disease at diagnosis should not preclude aggressive local control, except in cases of multicentric-metastatic disease.

Abstract
The complexity of pelvic anatomy and the extent of tumor growth makes treatment of patients with primary bone sarcomas in the pelvis difficult in terms of local control. Before the 1970s, most tumors in the bony pelvis were surgically treated with hindquarter amputation. Currently, improved techniques for clinical staging, adjuvant treatments, evolutions in metallurgy, and development of new surgical techniques make limb-salvage surgery and reconstruction possible alternatives to hemipelvectomy and resection-arthrodesis. The advantages of amputation over resections at the pelvis are a lower incidence of complications, a limited area at risk for recurrence, and a faster recovery time compared with all but the most limited pelvic resections. The disadvantages, especially after periacetabular resections, are leg-length discrepancy and impaired hip and gait function. The indication for limb salvage is the ability to obtain wide margins without compromising survival and function. Although having to resect the sciatic nerve to obtain adequate margins does not always mean that an amputation should be performed, the combination of a major pelvic resection and the functional consequences of sciatic nerve resection results in an extremity usually not worth saving; loss of femoral nerve function does not result in a significant gait disturbance, especially if the hemipelvis is stable. Reconstruction options after major pelvic resections have also evolved, but they remain difficult, especially when the acetabulum is involved.

Abstract
Patient: We report a 32-year-old women with a pelvic Ewing's sarcoma, who developed skeletal metastases within 20 months
of diagnosis but following treatment remains disease-free at 10 years. Discussion: Ewing's sarcoma is a highly malignant tumour of bone. Presentation of a pelvic tumour over the age of 30 years
is extremely rare and associated with a poor prognosis. Early recurrence is also associated with an extremely grave prognosis.
In our patient there was little or no response to salvage chemotherapy, but, against the odds, remission was induced
with pamidronate and palliative radiotherapy to some but not all sites of disease.This remission has been maintained without
additional therapy for a further 5 years.

Abstract
Purpose:To look at the presenting features, Enneking stage, size of primary tumour, method of treatment and patient and
doctor delays in upper extremity Ewing's sarcoma to observe the effects on local recurrence, metastasis and survival. Patients and methods:Nineteen patients with upper extremity Ewing's sarcoma were identified using the Scottish Bone
Tumour Registry over the past 40 years. Results:With increasing tumour Enneking stage at presentation there was a significantly higher mortality (P=0.02).
Patients with a higher Enneking stage also had an increased trend towards local recurrence (P=0.08). Stage did not
influence the occurrence of metastasis. Patients with larger tumours tended to have a higher mortality (50 vs. 27% dead at 5
years). All patients presented clinically with pain and all but two complained of some sort of swelling. There was a trend
towards a higher Enneking Stage in patients presenting with a longer duration of symptoms (P=0.1). No difference in
survival was noted between patients undergoing surgery and chemotherapy and patients undergoing radiotherapy and
chemotherapy. Disease-free survival was 100% at both 5 and 10 years for Enneking stage IIA, 56% at 5 and 10 years for
stage IIB and 0% at 5 years for stage III. Discussion:This study re-emphasises the potential importance of a diagnostic delay on outcome. Longer symptom duration
is associated with a higher Enneking stage at presentation. In turn a higher presenting stage results in a higher mortality.
Pain and swelling are prominent clinical findings at first presentation in upper extremity Ewing's.

Abstract
BACKGROUND Despite advances in adjuvant therapy, Ewing's sarcoma of the pelvis remains an anatomic site with a poor prognosis due to its relative inaccessibility, complex anatomy, and limited reconstructive options available. This study evaluates the role of surgery in the management of patients with pelvic Ewing's sarcoma who also have received conventional radiation therapy and chemotherapy. MATERIALS AND METHODS From July 1990 to July 2006, we received 10 patients with Ewing's sarcoma of pelvis at our center. Nine patients were in stage II B and one in Stage III at the time of presentation to us. All patients underwent surgical resection after preoperative chemotherapy with or without radiotherapy, which was given at the discretion of the referral center. Reconstruction was attempted using plate osteosynthesis in four patients, SS wires and screws in three patients, free fibular strut graft in one patient, and none was done in two patients. RESULTS Functional outcome assessed by Enneking's criteria revealed excellent outcome in two patients, good outcome in five patients, and poor outcome in two patients. At a mean followup of 10.3 years, seven patients remained free from the disease, and three patients died. The 5- and 10-year cumulative survival (Kaplan Meier method) was 63% and 34%, respectively. CONCLUSION This study demonstrates that surgery plus chemotherapy and radiation therapy is helpful for treating patients with pelvic Ewing's sarcoma, particularly in achieving local control.

Abstract
We review the treatment of pelvic Ewing’s sarcoma by the implantation of extracorporeally-irradiated (ECI) autografts and compare the outcome with that of other reported methods. We treated 13 patients with ECI autografts between 1994 and 2004. There were seven males and six females with a median age of 15.7 years (interquartile range (IQR) 12.2 to 21.7). At a median follow-up of five years (IQR 1.8 to 7.4), the disease-free survival was 69% overall, and 75% if one patient with local recurrence after initial treatment elsewhere was excluded. Four patients died from distant metastases at a mean of 17 months (13 to 23). There were three complications which required operative intervention; one was a deep infection which required removal of the graft. The functional results gave a mean Musculoskeletal Tumor Society score of 85% (60% to 97%), a mean Toronto extremity salvage score of 86% (69% to 100%) and a mean Harris hip score of 92 (67 to 100). We conclude that ECI grafting is a suitable form of treatment for localised and resectable pelvic Ewing’s sarcoma.

Abstract
The outcome of Ewing's sarcoma depends on the anatomical site of the tumor. Studies conducted in high-risk patients are limited. We evaluated the outcome of high-risk Ewing's sarcoma patients that received long-term treatment protocol. Twenty-five patients (22 males, 3 females) with poor prognostic features were treated according to long-term Ewing's sarcoma protocol. Central-axis localization, inadequacy or unavailability of surgical resection, older than 15 years of age, are accepted as high-risk factors. The median age of patients was 23 years (range, 18-55). The tumor localization was pelvis (9), femur (1), tibia (1), fibula (1), maxilla (1), clavicle (1), vertebrae (5), metatarse (1), and ribs (5). Neoadjuvant chemotherapy was applied between weeks 0 and 6, local therapy on week 9, and adjuvant maintenance chemotherapy between weeks 11 and 41. All patients received neoadjuvant and adjuvant maintenance chemotherapy. Local therapy consisted of radiotherapy (32%), surgery alone (12%), or surgery and radiotherapy (56%). The median total treatment period was 10 months. The median follow-up was 25 months (range, 7-89). Three-year cumulative OS and DFS rates were 43% (95% CI, 28.5-57.85) and 40% (95% CI 23.63-52.19), respectively. The most common grade III/IV toxicities observed during the treatment protocol were neutropenia (16%) and gastrointestinal toxicities (16%). Our study indicated that long-term multiagent combination chemotherapy may result in better outcome in adult high-risk patients undergoing adequate surgical resection of the tumor and local radiotherapy. Further randomized studies are needed to assess the efficacy of this treatment protocol in patients with adequate surgical margins.

Abstract
PURPOSE This retrospective analysis describes our 35-year experience with respect to disease control and functional status. PATIENTS AND METHODS Thirty-five patients with localized Ewing tumors of the pelvis and sacral bones were treated from 1970 to 2005. Twenty-six patients were treated with definitive radiotherapy (RT), and 9 patients were treated with combined local therapy in the form of surgery + RT. The median RT dose was 55.2 Gy. The patients who received RT alone were more likely to be older men with larger tumors exhibiting soft-tissue extension. Patients in the definitive RT group were more likely to receive etoposide and ifosfamide or undergo bone marrow transplant. Median potential follow-up was 19.4 years. RESULTS The 15-year actuarial cause-specific survival, freedom from relapse rate, and local control rates were 26% vs. 76% (p = 0.016), 28% vs. 78% (p = 0.015), and 64% vs. 100% (p = 0.087), respectively, for patients treated with definitive RT and combined therapy. Overall, tumors <8 cm had significantly better cause-specific survival, but this was unrelated to local control. The median Toronto Extremity Salvage Score for the definitive RT and combined therapy groups were 99 and 94, respectively (p = 0.19). Seven definitive RT patients (27%) had serious complications. CONCLUSION Combined modality local therapy should be considered if pelvic Ewing tumors are resectable. However, because of the extent of local disease, most patients have unresectable or partially resectable tumors and therefore require RT in some capacity. For this reason, innovative RT strategies are needed to improve long-term disease outcomes and minimize side effects while maintaining an acceptable functional result.

Abstract
Survival rates of children with pelvic sarcoma have demonstrated unprecedented improvement during the past few decades, with a corresponding increase in the number of limb-sparing surgical procedures being performed. This increase may be attributed to earlier detection with advanced imaging techniques, the availability of a wider armamentarium of surgical techniques of reconstruction and limb salvage, and advances achieved in neoadjuvant chemotherapy and radiation therapy. Undertaking reconstruction after resection of pelvic sarcoma while preserving function of the hip and limb can be extremely challenging; this is especially true in children, who invite concern regarding growth potential and limb-length discrepancy. Decisions for surgery and reconstruction are individualized based on tumor type, size, and location as well as the probability of achieving a wide resection with negative margins and acceptable morbidity.

Abstract
BACKGROUND Reconstruction of the pelvic arch after resection of a malignant pelvic tumor remains a major surgical challenge because of the high rate of associated complications. The purpose of this investigation was to assess the functional outcome and complication rate following treatment with a bone allograft to reconstruct the pelvis. METHODS Twenty-four consecutive patients underwent excision of a malignant pelvic bone tumor and reconstruction with a pelvic bone allograft. The living patients were followed for a minimum of twenty-four months. There were nineteen primary malignant bone tumors, sixteen of which were high-grade sarcomas, and there were five isolated metastases. Patients were examined clinically and radiographically and were assessed functionally with the Musculoskeletal Tumor Society score. RESULTS The mean age of the patients at the time of the index surgery was thirty-four years, and the mean duration of follow-up was forty-one months. Eighteen of the twenty-four resections involved the periacetabular area and were followed by reconstruction either with a hip prosthesis (thirteen) or with an osteochondral allograft alone (five). The six other resections involved the iliac bone. All patients received a massive bone allograft that had been sterilely procured without secondary irradiation. At the time of our last evaluation, eight patients were alive and free of disease. Seven patients had a local recurrence. Neurological deficits were present in six patients, and three had a deep infection. Nonunion of three of the sixteen allografts that could be evaluated was observed. Neither graft fracture nor lysis was observed. Eleven patients underwent surgical revision, with nine of these revisions related to the reconstruction. The average Musculoskeletal Tumor Society score at the time of the latest follow-up was 73% of the maximal possible score. The average score was 82% for the eleven patients with an age of less than twenty years at the time of the index procedure and 65% for the thirteen older patients. Ten patients walked without any assistive device, and five of them had normal function with no or only a slight limp. CONCLUSIONS Pelvic reconstruction after a limb-sparing resection is associated with a high risk of surgical complications and usually should be reserved for patients with a primary bone sarcoma. A pelvic allograft can restore the anatomy and provide good functional results, especially in young patients. Nonunion was the most common allograft-related complication.

Abstract
Ewing's sarcoma of the pelvis traditionally has been a difficult problem in orthopaedic oncology. Multiple studies have had inferior outcomes when compared with outcomes of patients with similar stage disease involving only the extremities. A major reason for this discrepancy is the difficulty associated with resection and reconstruction of pelvic tumors. Often the tumors are deemed nonresectable and are treated with chemotherapy and radiation or radiation alone. Patients treated in this manner have lower 5-year survival rates, higher local recurrence rates, and multiple long-term complications. The case of a 4-year-old girl with Ewing's sarcoma of the left hemi-pelvis is reported. Combined with adjuvant chemotherapy, this patient was treated with resection followed by osteoarticular allograft reconstruction. At 2 years followup, the patient was disease-free with an excellent functional outcome.

Abstract
The purpose of this study was to evaluate the outcome of patients with Ewing sarcoma (ES) of the pelvis, attempting to identify prognostic factors to select patients for more aggressive treatment. Seventy-seven patients with nonmetastatic ES of the pelvis were treated at Rizzoli Institute between 1979 and 1996. Four different protocols of chemotherapy were used successively. Two protocols consisted of VACAc, and two of VACAc plus ifosfamide and etoposide. Local treatment consisted of surgery in 5 patients, radiotherapy in 60, and surgery followed by radiotherapy in 12. Mean follow-up was 11 years (range 5-25 years). Thirty-three patients remained continuously free of disease; 43 relapsed (24 due to metastases and 19 to local recurrence and metastases); 1 died of treatment-related complications. The 5- and 10-year event-free survival rates were 45% and 44%, respectively, and the 5- and 10-year overall survival rates were 48 and 44. These results are significantly worse than the ones achieved in 329 contemporary patients with extrapelvic lesions treated with the same protocols of chemotherapy (5- and 10-year event-free survival = 46% vs. 64% and 44% vs. 69%). Thus, despite associated chemotherapy, the outcome of ES localized in the pelvis remains poor, and new innovative methods for the treatment of this tumor are needed.

Abstract
Thirty patients younger than 19 years with malignant bone tumors of the pelvis were treated by limb salvage surgery between 1970 and 1998. Functional and oncologic results were reviewed retrospectively. In 10 patients the defect was reconstructed by an endoprosthesis and in 20 patients reconstruction by autologous grafts (n = 7), allograft and prosthesis combinations (n = 2), bone cement reconstruction (n = 1), iliosacral arthrodesis (n = 1), modified Girdlestone procedure (n = 3), or resection without reconstruction (n = 6) was done. Three and one-half reoperations per patient were necessary postoperatively after allograft reconstruction, 2.5 reoperations per patient were necessary after endoprosthetic reconstruction, and 0.8 reoperations per patient were necessary after other or no reconstruction. After a mean followup of 52 months (range, 2-241 months), 17 patients were alive, 15 of whom were continuously disease-free, and 13 patients had died of their disease. Functional ratings were 81% after autograft, 73% after allograft, and 60% after endoprosthetic reconstruction. Defect reconstruction varied according to the type of resection. Type I resections were best reconstructed by biologic methods. Endoprosthetic reconstruction after periacetabular resection with the advantage of preservation of a functional hip and body integrity was associated with a high rate of complications and reoperations. Its role compared with allograft reconstruction, modified Girdlestone procedure, or no reconstruction requires additional investigation.

Abstract
The oncologic outcome in the treatment of pelvic sarcomas is not comparable with that in the extremity. Particular problems arise when the tumor involves the posterior pelvis and the sacrum or even the lower lumbar spine. Because of the difficulty in achieving local control and the major functional deficits after extensive surgery, some authors suggest conservative, nonsurgical treatment for these patients. The purpose of the current study was to analyze the oncologic outcome of patients who were treated for a pelvic sarcoma necessitating resection of the ilium, part of the sacrum and part of the lower spine, which is defined as extended hemipelvectomy. Between 1979 and 1999, 11 males and seven females with a mean age of 34.5 years (range, 14-67 years) had an extended hemipelvectomy for a sarcoma of the posterior pelvis. The tumors included seven osteogenic sarcomas, six chondrosarcomas, and five fibrosarcomas: 13 were classified as high-grade lesions. The mean size of the tumor was 11 x 9 x 6 cm. In 11 patients, a hemivertebrectomy of L5 and in seven patients of L4 combined with L5 was done to achieve an adequate margin. In four patients, the resection was followed by reconstruction with a vascularized fibula or autograft. At a mean followup of 56 months (range, 3-220 months), 12 of 18 patients were alive and without disease. Six patients died; four of these patients had metastasis to the lung at presentation. The two remaining patients died of complications of adjuvant treatment. The authors conclude from this small series of patients that an aggressive surgical resection for localized, nonmetastatic, high-grade sarcomas of the posterior pelvis may be justified to provide local control and improve survival.

Abstract
Great strides have been made in the diagnosis and treatment of patients with Ewing's sarcoma. With the advent of modern chemotherapy, the long-term survival has improved to approximately 70%. Standard treatment for local control of the primary lesion has, historically, been chemotherapy and radiation. Currently, surgical resection has become a more effective option in the multidisciplinary treatment of patients with this disease. These current concepts and developments in the presentation and management of Ewing's sarcoma are discussed.

Abstract
AIMS Pelvic bone sarcomas in children and young adults are rare, and associated with a poor prognosis and a high rate of local recurrence. Primary goals of treatment include prevention of local recurrence and distant metastases. A secondary goal is maintenance of quality of life by avoiding major amputative surgery. This is why internal hemipelvectomy (a limb-sparing surgery) is advocated whenever possible. The focus of our presentation is surgical issues in the context of resection and reconstruction of the pelvis in the first two decades of life. MATERIALS AND METHODS Between January 1988 and June 1998, 27 patients were treated and operated on (follow-up time 1.5-12 years). There were 17 males and 10 females. Their age ranged between 2 and 22 years. There were 24 patients with Ewing's sarcoma (ES) and three with other bone sarcomas. In 19 patients the tumour involved the entire or part of the iliac bone (in some cases with extension to the sacrum). In five patients the tumour involved the pubis and/or ischium. In three patients the tumour involved the sacrum with some extension to the posterior iliac bone. All patients received neoadjuvant and adjuvant chemotherapy and radiotherapy with different protocols (related to the origin of referral). RESULTS Twenty-seven patients underwent internal hemipelvectomy. According to Enneking's classification there were: type I-10; type II-one; type III-six; type IV-five (including one localized sacrectomy); type I+IV-five patients. In 15 patients some kind of reconstruction was needed and in 12 no reconstruction was done. Four wound infections occurred that were managed successfully by surgical debridement, antibiotics and local wound care. In one case removal of the 'implant' was needed. No primary or secondary amputations were performed in the series. The rate of local recurrence was 22%. Functional status at the last follow-up visit or before death, according to the AMSTS functional rating system: excellent-six; good-17; fair-three and poor-one. All patients except the one poor result maintained their walking ability during the follow-up time. CONCLUSIONS Internal hemipelvectomy is achievable in most cases and justified for better quality of life in children, adolescents and young adults with sarcomas. Further efforts are needed to improve the reconstructive options in the pelvis.

Abstract
BACKGROUND The time between the initial symptoms of osteosarcoma and Ewing sarcoma and the correct diagnosis and treatment is long. Over the last two decades, the prognosis for patients with these diseases has dramatically improved due to a new chemotherapy regimen. As a consequence, a limb-sparing operation has become an alternative to amputation. The aim of this study was to establish the initial symptoms and physical signs of osteosarcoma and Ewing sarcoma from the records of the first medical visit and to identify early characteristics of the diseases to shorten the delay to diagnosis. METHODS A group of patients with osteosarcoma or Ewing sarcoma was identified from the Swedish Cancer Register of patients thirty years old and younger. Records from the first medical visit due to symptoms related to the bone tumor were obtained for 102 patients with osteosarcoma and forty-seven patients with Ewing sarcoma. RESULTS Pain related to strain was reported by eighty-seven (85 percent) of the patients with osteosarcoma and thirty (64 percent) of those with Ewing sarcoma, but only twenty-one (21 percent) of the patients with osteosarcoma and nine (19 percent) of those with Ewing sarcoma reported pain at night. Forty-eight (47 percent) of the patients with osteosarcoma and twelve (26 percent) of those with Ewing sarcoma related the onset of symptoms to minor trauma occurring around the same time. A palpable mass was noted in forty (39 percent) of the patients with osteosarcoma and sixteen (34 percent) of those with Ewing sarcoma at the first visit, and in most cases the tumor diagnosis was suspected. There was a broad spectrum of misdiagnoses; the most common was tendinitis, which was the initial diagnosis in thirty-two (31 percent) of the patients with osteosarcoma and ten (21 percent) of those with Ewing sarcoma. The doctor's delay (the period from the first medical visit due to the symptoms to the correct diagnosis) was longer for Ewing sarcoma than for osteosarcoma (nineteen weeks and nine weeks, respectively; p < 0.0001). CONCLUSIONS An initial symptom of both osteosarcoma and Ewing sarcoma was pain, which was intermittent and often related to strain but not frequently felt at night. A history of trauma was common, but the clinical course often diverged from what was expected from trauma. The clinical course of osteosarcoma and particularly of Ewing sarcoma was not steadily progressive but intermittent, which often misled the doctor into believing that the condition was temporary. The most important clinical feature was a palpable mass, which was noted in more than one-third of the patients at the first visit. This finding emphasizes that a thorough physical examination is absolutely necessary.

Abstract
Thirty-one patients with chondrosarcoma of the pelvis were reviewed. The median followup period of the surviving patients was 66 months. Thirteen of 23 tumors after surgery with inadequate margins (57%) and 1 of 8 after surgery with adequate margins (13%) relapsed locally. Four of 10 patients had local recurrence, 2 of 2 patients had metastasis, and 4 of 4 patients who had local recurrence and metastasis died. A cumulative 10-year overall survival of patients with pelvic chondrosarcoma was 54%. Patients who had primary or high grade chondrosarcoma had a poor prognosis. Multivariate analysis (Cox proportional hazard model) showed that tumor type was the most important prognostic factor. Eight patients underwent hindquarter amputation, 6 patients had resection alone, and 17 patients had resection and reconstruction as follows: 3 interpubic arthrodeses, 2 iliosacral arthrodeses, 3 ischiofemoral arthrodeses, 8 hip prostheses (3 prostheses alone and 5 prostheses with allograft), and 1 hip transposition. Failure of reconstruction was attributed to infection in 5 patients, local recurrence of tumor in 5, and local recurrence and fracture of implant in 1 patient.

Abstract
We reviewed the treatment outcome of 69 patients with Ewing's sarcoma of the femur. The patients received chemotherapy according to the CESS 81 (n 14), CESS 86 (n 43), and CESS 91P (n 12) protocols. The 10-year relapse-free survival rates were 36%, 65%, and 65% (p = 0.01). 68 patients received local treatment. The primary tumor was treated by surgery without radiotherapy in 28 patients; 1 developed a local recurrence and 7 metastases. 10 patients received radiotherapy alone; 4 developed metastases and 4 local recurrences and metastases. 30 cases had a combination of surgery and radiotherapy; 7 developed metastases and 1 a local recurrence and metastasis. The survival of patients after radiotherapy alone was worse than that of patients after surgery with/without radiotherapy (p = 0.005). Pathological fractures (n 16) did not influence the prognosis.

Abstract
The translocation t(11;22) is a common chromosomal abnormality detected both in Ewing's sarcoma and in primitive neuroectodermal tumor cells. The translocation results in an EWS-Fli1 fusion gene, made up of the 5' half of the EWS gene on chromosome 22 fused to the 3' half of the Fli1 gene on chromosome 11. Recent studies have evaluated possible roles of the fusion gene products. However, the biological significance of EWS-Fli1 is still unknown. Using a competitive polymerase chain reaction technique, we show here that there might be a correlation between the expression levels of the EWS-Fli1 fusion gene and the proliferative activities of Ewing's sarcoma and primitive neuroectodermal tumor cells. When the EWS-Fli1 expression is inhibited by antisense oligodeoxynucleotides against the fusion RNA, the growth of the tumor cells is significantly reduced both in vitro and in vivo. The data further indicate the growth inhibition of the cells by the antisense sequence might be mediated by G0/G1 block in the cell cycle progression. These results suggest that EWS-Fli1 may play an important role in the proliferation of the tumor cells, and the EWS-Fli1 fusion RNA could be used as a target to inhibit the growth of Ewing's sarcoma and primitive neuroectodermal tumor with the specific antisense oligonucleotide.

Abstract
The influence of preoperative irradiation on surgical complications in 42 patients with Ewing's sarcoma was analysed. After preoperative irradiation and chemotherapy, 35 of 40 patients showed a good histological response and 25 of 40 patients had no viable tumour cells in the resected specimen. Local relapse alone did not develop, local relapse and metastasis developed in 2 patients and metastasis alone in 15 patients. Surgical complications appeared in 12 of 42 patients: 9 of 19 central tumours (19 pelvic lesions), 1 of 13 proximal and 2 of 10 distal tumours. Surgical complications after preoperative irradiation are distributed as follows: delayed wound healing 8, hematoma 2, thrombosis 2, skin infection 1, and abscess 1. On the other hand, complications appeared in 2 of 28 patients without preoperative irradiation: none in 9 patients having central tumours including 2 pelvic lesions, 1 in 12 patients with proximal tumours, and 1 in 7 patients with distal tumours. The multivariate regression test showed that the tumour site (central) is an influencing factor in the appearance of surgical complications. In central tumours, the surgical complication rate increases after preoperative irradiation; however, it is affected by the increase of the ratio of patients with pelvic tumours.

Abstract
Limb-salvage surgery is a safe and effective treatment for malignancies of the musculoskeletal system. Careful evaluation and planning are necessary to avoid both early and late complications. Biopsy must be carefully performed to avoid unnecessary contamination and to obtain adequate tissue for an accurate diagnosis. Pathologic fractures present both a diagnostic and a therapeutic challenge, and evaluation strategies depend on the age of the patient. Treatment of a pathologic fracture depends on the location and the histology of the lesion and many host factors. Limb salvage may or may not be indicated. Instability is another problem with certain limb-salvage situations, e.g., when it is necessary to resect the scapula. Various approaches may obviate the problem. The salvage of failed limb-salvage procedures requires careful evaluation and planning. Patients with infections and local recurrences often require amputation surgery. Correctable problems following failed allograft reconstructions include collapse of the articular cartilage, joint instability, nonunion, and fracture of the allograft. Correctable problems following prosthetic arthroplasty include aseptic loosening, prosthetic fracture, and polyethylene wear. Approximately two thirds of patients with failed limb-salvage procedures will obtain a functional limb following revision surgery. Attention to these special problems may allow for greater success with limb-salvage surgery.

Abstract
BACKGROUND There is little information regarding an adequate surgical margin for local control of Ewing's sarcoma. METHODS Two hundred and forty-four patients (PTS) with Ewing's sarcoma who were registered in the Cooperative Ewing's Sarcoma Studies underwent surgical treatment. Ninety-four PTS underwent definitive surgery (surgery alone), 131 PTS received postoperative irradiation, and 19 PTS received preoperative irradiation. The surgical margins were distributed as follows: radical, 29 PTS; wide, 148 PTS; marginal, 39 PTS; and intralesional, 28 PTS. The impact of the surgical margin on the treatment outcome of PTS was analyzed statistically. RESULTS The local or combined (local recurrence and systemic metastasis) relapse rate after surgery with or without irradiation was significantly lower compared with that after definitive irradiation (irradiation alone) (7% vs. 31%, P < 0.0001). The local or combined relapse rate after complete resection (radical or wide margin) with or without irradiation was less compared with that after incomplete resection (marginal or intralesional margin) with or without irradiation (5% vs. 12% P = 0.0455). The local or combined relapse rate did not greatly decreased after irradiation after incomplete surgery (from 14% to 12%). In both groups of good (viable tumor cells < 10%) and poor (viable cells > or = 10%) histologic response, the difference in systemic or combined relapse rate between patients undergoing complete and incomplete surgery was not significant. The 10-year overall survival of the PTS for each of the margins was distributed as follows: radical, 58%; wide, 65%; marginal, 61%; and intralesional, 71% (P = not significant). CONCLUSIONS Surgery in patients with Ewing's sarcoma adds to the safety of local control. Under the current treatment regimen with intensive chemotherapy and irradiation, complete resection of the tumor appears capable of decreasing the risk of local recurrence.

Abstract
BACKGROUND The treatment of Ewing's sarcoma consists of chemotherapy for systemic and local disease. However, the role of radiation therapy, and/or surgical resection for definitive local treatment has yet to be determined. METHODS A retrospective review of 32 patients (24 males and 8 females) treated for femoral Ewing's sarcoma between 1970 and 1985 was performed. Patients were divided into 3 treatment groups: chemotherapy and radiotherapy (CR) (10); chemotherapy and surgery (CS) (9); and chemotherapy, surgery, and radiotherapy (CSR) (13). Patients in the CR group received a mean of 5320 centigray (cGy) of radiation and patients in the CSR group received a mean of 3590 cGy. Multiagent cyclophosphamide/doxorubicin based chemotherapy was used in all cases. Surgery consisted of wide resection or amputation. RESULTS Patients in the CR group had a higher risk of local recurrence than patients in the CS and CSR groups (P=0.02, log rank). The combination of local recurrences and treatment complications necessitated surgery for 7 of 10 CR patients, whereas 1 of 9 and 4 of 13 in the CS and CSR groups required additional surgery. The median survival for the entire group was 39 months. Minimum follow-up for surviving patients was 45 months. Five-year survival consisted of 1 of 10 patients in the CR group, 2 of 9 in the CS group, and 7 of 13 in the CSR group. There were no statistically significant differences among the three survival curves. Tumor location within the femur was a significant prognostic variable. Distal femoral location had a survival advantage compared with proximal and mid-femur locations (P = 0.049, log rank). CONCLUSIONS Femoral Ewing's sarcoma remains a disease with a poor prognosis. Radiation alone for local treatment results in a high rate of local recurrence and complications. Our current local treatment strategy for femoral Ewing's sarcoma includes surgery in all and adjuvant radiotherapy in many of the patients.

Abstract
BACKGROUND Despite advances in adjuvant therapy, Ewing's sarcoma of the pelvis remains an anatomic site with a poor prognosis. This study evaluate the role of surgery in the management of patients with pelvic Ewing's sarcoma who also received conventional radiation therapy and chemotherapy. METHODS From May 1978 to February 1994, 19 patients with Stage IIB Ewing's sarcoma of the pelvis were treated at the UCLA Medical Center (Los Angeles, CA). There were eight lesions of the ilium, two of the sacrum, and nine involving two adjoining regions of pelvis. All patients received conventional medical management. The 19 patients were divided into two groups according to treatment modality. A group of 12 patients (Group A) had surgical resection, and their results were compared with those of another group of 7 patients (Group B) who did not have surgery. RESULTS The 5-year cumulative survival (Kaplan-Meier method) was 39% for all patients, 51% for Group A, and 18% for Group B. The 3-year cumulative survival was 59% for all patients, 72% for Group A, and 36% for Group B. Although the survival rate of Group A seemed better than that of Group B, the difference was not statistically significant (P = 0.093, log rank method). This study also suggested that, regardless of treatment modality, the outcome of patients with lesions involving two adjoining pelvic bones was poorer than that of those with a single lesion. In Group A, the 3-year cumulative survival rate for patients with single bone lesions (n = 8) was 86% and for patients with lesions involving two adjoining pelvic bones (n = 4) was 50% (P = 0.045, log rank method). Furthermore, the statistical analysis of the combined data of the single pelvic bone lesions in UCLA and that of Mayo Clinic series (n = 16 for surgery group and n = 15 for nonsurgery group) confirmed the better results for the surgical patients, which was consistent with the results from the Mayo Clinic with an even greater significance (P < 0.002). CONCLUSION This study demonstrates that surgery plus chemotherapy and radiation therapy is helpful for treating patients with pelvic Ewing's sarcoma so long as the tumor is limited to a single pelvic bone.
