Abstract
BACKGROUND Time to diagnosis (TTD) of childhood soft tissue sarcoma (STS) is significantly associated with survival. This review aims to identify pre-diagnostic symptoms/signs to inform earlier diagnosis interventions. METHODS Medline, Embase, Cochrane and Web-of-Science were searched between January 2010 and February 2021 for studies including children (<18 years) diagnosed with STS, with no language restrictions. Pooled proportions of symptoms/signs were calculated and subanalysed by tumour location and age. RESULTS Fifty-nine eligible studies were identified, totalling 2462 cases. The most frequent symptoms were lump/swelling (38%, 95% CI 27% to 51%), pain (6%, 95% CI 3% to 10%), cutaneous changes (4%, 95% CI 0 to 9%), localised eye swelling (3%, 95% CI 0 to 7%), cranial nerve deficits (2%, 95% CI 0 to 5%) and constitutional symptoms (2%, 95% CI 0 to 5%).Symptoms varied by location and age. Localised eye swelling (20%, 95% CI 3% to 45%), cranial nerve deficits (14%, 95% CI 4% to 28%) and impaired visual function (6%, 95% CI 0 to 17%) were frequent in head and neck tumours. For abdomen/pelvic tumours, urinary symptoms (24%, 95% CI 5% to 15%), abdominal distension/discomfort (22%, 95% CI 4% to 47%), genital lump/swelling (16%, 95% CI 1% to 42%), constitutional symptoms (9%, 95% CI 0%] to 23%), vaginal bleeding (7%, 95%C I 0 to 21%) and bowel habit changes (6%, 95% CI 0 to 17%) were frequent.In <5 years, consumptive coagulopathy (16%, 95% CI 0 to 48%), cutaneous changes (5%, 95% CI 0 to 40%), genital lump/swelling (4%, 95% CI 0 to 14%), reduced mobility (3%, 95% CI 0 to 11%), vaginal bleeding (2%, 95% CI 0 to 11%) and bleeding/bruising/petechiae (2%, 95% CI 0 to 20%) were frequent compared with lump/swelling, constitutional symptoms, pain and headaches which were frequent among >11 years. CONCLUSIONS For STS, pre-diagnostic symptoms differ by age and location, highlighting the need to tailor early diagnosis interventions.

Abstract
Synovial sarcomas are high-grade soft tissue sarcomas of primitive mesenchymal origin which are defined by a pathognomonic t(X;18)(p11,q11) translocation, and which occur in pediatric and adult populations. Herein we report a case of a 33-year-old female with a history of nasopharyngeal carcinoma status post radiotherapy, presenting with a poorly differentiated synovial sarcoma of the nasal cavity arising in the radiation field. While the development of radiation-associated sarcoma is a known complication of radiotherapy, to date only 10 cases of synovial sarcoma have been reported to occur in previously irradiated tissues. Moreover, only 1 case of poorly differentiated synovial sarcoma involving the nasopharynx has been described.

Abstract
Non-rhabdomyosarcoma soft-tissue sarcomas (NRSTS) comprise 4% of childhood cancers and consist of numerous histologic subtypes. Prognostic factors associated with poor outcome include high histologic grade, large tumor size, presence of metastases, and unresectability. Complete surgical resection is critical for the best oncologic outcomes and is prioritized in treatment algorithms. The use of radiation therapy (RT) and chemotherapy is based upon factors such as resectability, histologic grade, tumor size, and stage. North American and European trials are defining a risk-based approach to NRSTS to limit treatment-related toxicity and to maximize therapeutic efficacy. In this paper, we summarize the current roles of surgery, RT, and chemotherapy in NRSTS and describe ongoing research that is advancing the care of NRSTS patients.

Abstract
Neonatal sarcomas comprise a heterogeneous group of rare soft tissue neoplasms that present unique diagnostic and therapeutic challenges. Recent advances in molecular profiling have improved diagnostic capabilities and reveal novel therapeutic targets. Clinical trials demonstrate differences in behavior between sarcoma subtypes that allow for better clinical management. Surgical resection has been replaced with a multimodal approach that includes chemotherapy and radiotherapy. Despite these advances, neonates with sarcoma continue to fare worse than histologically similar sarcomas in older children, likely reflecting differences in tumor biology and the complexities of neonatal medicine. This review focuses on recent advances in managing neonatal sarcomas.

Abstract
PURPOSE OF REVIEW Nonrhabdomyosarcoma soft tissue sarcoma (NRSTS) is a rare subgroup of malignancy in childhood that is composed of a variety of soft tissue and bony tumors. Prognosis for resectable localized disease is usually good and improved with systemic treatment. However, survival from locally advanced and metastatic disease remains poor. There have been numerous preclinical and clinical studies to define histopathology, biology, and genetic alteration of sarcomas. The purpose of this review is to clarify the progress in the management of NRSTS. RECENT FINDINGS Genomic analysis, including the use of next-generation sequencing, has revealed fusion transcripts or specific genetic alterations which provide diagnostic biomarkers and potential targets for novel therapies. SUMMARY Most cases are sporadic, but some are associated with genetic predispositions. Most present as a painless mass and diagnosis is frequently delayed because of a low index of suspicion. There is a wide array of histopathological subtypes. Investigations usually involve core, incisional or excisional biopsy for tissue diagnosis, and cross-sectional and nuclear imaging for staging. Management of pediatric sarcoma is largely dependent on the patient's histopathological diagnosis, age, disease stage, and co-morbidities but usually involves a combination of systemic and local therapies. Preclinical studies and phase I/II trials of newer targeted therapies are ongoing.

Abstract
Metastatic disease and the complications of treating metastatic disease are the primary causes of mortality in children with solid malignancies. Nearly 25% of children with solid tumors have metastatic disease at initial diagnosis and another 20% develop metastases during or after treatment. The most common location of these metastases is the lung. The role of surgery in metastatic disease depends greatly on the histology of the primary. In general, tumors that are refractory to adjuvant therapies are most appropriate for pulmonary metastasectomy. This article will summarize the indications for metastasectomy in pediatric solid tumors and discuss the ongoing debate over the technique of metastasectomy in osteosarcoma.

Abstract
Most children who succumb to solid malignancies do so because of the burden of metastatic disease or due to complications associated with the therapy administered to treat metastatic disease. Approximately one-quarter of children with solid tumors will present with metastatic disease, and an additional 20% ultimately develop metastatic disease, most commonly in the lung. The role of surgery in the treatment of metastatic solid tumors, given its disseminated nature, is not intuitive, yet there are circumstances in which surgical resection of metastatic disease can potentially be curative. However, the utility of surgery is very much dependent on histology, and generally is most appropriate for those malignancies with histologies that are refractory to other adjuvant therapies.

Abstract
OBJECTIVES Treatment of soft tissue tumors in young patients relies on the diagnostic information conveyed in the pathology report. We examined pathology reports from Children's Oncology Group ARST0332 for inclusion of data elements required in published guidelines. METHODS Pathology reports for 551 eligible patients were examined for required data elements defined by the College of American Pathologists, including tissue type, procedure, tumor site, tumor maximum diameter, macroscopic extent of tumor, histologic type, mitotic rate, extent of necrosis, tumor grade, margin status, use of ancillary studies, and pathologic stage. RESULTS Only 65 (12%) of 551 reports included all required data elements. Of reports containing synoptic templates, 57% were complete. CONCLUSIONS This study reveals significant opportunity to improve the quality of pathology reports in young patients with soft tissue tumors. Use of templates or checklists improves completeness of reports.

Abstract
Paediatric soft tissue sarcomas (STS) are a group of malignant tumours that originate from primitive mesenchymal tissue and account for 7% of all childhood tumours. Rhabdomyosarcomas (RMS) and undifferentiated sarcomas account for approximately 50% of soft tissue sarcomas in children and non-rhabdomyomatous soft tissue sarcomas (NRSTS) the remainder. The prognosis and biology of STS tumours vary greatly depending on the age of the patient, the primary site, tumour size, tumour invasiveness, histologic grade, depth of invasion, and extent of disease at diagnosis. Over recent years, there has been a marked improvement in survival rates in children and adolescents with soft tissue sarcoma and ongoing international studies continue to aim to improve these survival rates whilst attempting to reduce the morbidity associated with treatment. Radiology plays a crucial role in the initial diagnosis and staging of STS, in the long term follow-up and in the assessment of many treatment related complications. We review the epidemiology, histology, clinical presentation, staging and prognosis of soft tissue sarcomas and discuss the role of radiology in their management.

Abstract
Nonrhabdmyosarcoma soft tissue sarcoma (NRSTS) is a heterogenous group of tumors analyzed as a unique group because of the rarity of each histopathological subtype. Initial information available has been obtained from adult series or pediatric case studies. Recent reports by several multi-center groups have been published that evaluated prognostic factors and treatment protocols. Established prognostic factors include tumor grade, invasiveness, size, and intergroup rhabdomyosarcoma study (IRS) group. Identification of sarcoma-specific chromosomal translocations has allowed for more accurate definitive diagnosis. Some may have prognostic significance and may offer as potential therapeutic targets. Surgery remained important, as many of the tumors are scarcely chemosensitive. With the development of multimodalities, surgical management has evolved over the years. Patients with localized unresectable disease are managed with surgery +/- radiotherapy with very good results. Localized unresectable disease is intermediate in behavior and prognosis. Patients are treated with neoadjuvant chemotherapy, +/- radiotherapy, followed by delayed surgical resection. Prognosis in patients with metastatic disease has been poor despite combination chemotherapy with surgical resection. The addition of ifosfamide and doxorubicin in the chemotherapy regimes has provided some improvement. With the lack of new active agents, we will depend on advances in molecular techniques to develop novel targeted therapies, better molecular markers and histology-specific trials to evaluate this group of tumors.

Abstract
This article describes the historical development of pediatric pulmonary metastasectomy but demonstrates that progress has been slow in understanding its proper applications. Because many pediatric metastatic tumors are rare, surgeons have grouped together patients of different histologies for the generation and analysis of case series. By examining tumor types individually, however, it is seen that certain histologies (adrenocortical carcinoma, alveolar soft part sarcoma, osteosarcoma) mandate surgical metastasectomy for patient survival. Other pediatric tumors (Wilms tumor, Ewing's sarcoma) are radiation sensitive, and the application of metastasectomy is controversial. In the case of still other types of tumor (neuroblastoma, differentiated thyroid cancer, rhabdomyosarcoma), metastasectomy is seldom performed except in highly unusual situations. Techniques for minimally invasive biopsy and for muscle-sparing thoracotomy are described for pediatric patients.

Abstract
Perivascular epithelioid tumor (PEComa), a recently defined tumor, is a very rare disease affecting various organs, most often the uterus. This tumor displays a variety of histologic and clinical features and at this point is regarded as a tumor with uncertain malignant potential. A 9-year-old girl with abdominal pain and vaginal spotting was diagnosed with PEComa of the uterus with metastasis. She received chemotherapy comprising vincristine, ifosfamide, and doxorubicin, as well as radiotherapy after surgery. After this multimodal treatment, there was no evidence of recurrence or further metastasis. She remains disease-free 1.5 years after her initial diagnosis. PEComa of the uterus displaying malignant characteristics may have a more favorable response to more aggressive therapy.

Abstract
OBJECTIVE To determine the value of postoperative radiotherapy (RT) in the management of nonrhabdomyosarcoma soft tissue sarcoma (NRSTS) of childhood. PROCEDURE From 1964 to 2000, 62 children with a median age of 14 years were seen at the University of Iowa and underwent a wide local excision for non-metastatic NRSTS. Tumors were high grade in 36 (58%) and >5 cm in 24 (39%). Margins of resection were negative (Group I) in 37 (60%) and positive (Group II) in 25 (40%). Postoperative RT was delivered to 20 patients (32%); eight of 37 (22%) Group I and 12 of 25 (48%) Group II children received postoperative RT. Chemotherapy was employed in 19 patients (31%). Median follow-up was 9.6 years. RESULTS The 5- and 10-year overall survival rates for Group I were 69 and 63% and for Group II were 66 and 60%. The 5- and 10-year local control rate was 66%. On multivariate analysis, size of tumor (P < 0.001) and postoperative RT (P = 0.017) were prognostic factors for local control. All 13 Group I children with low grade, </=5 cm tumors were locally controlled without RT. For Group II patients, 2- and 5-year local control rates were 92 and 82% with postoperative RT and 51 and 43% for no RT (P = 0.0426). CONCLUSIONS Local control was improved by the addition of postoperative RT in tumors with positive margins of resection.

Abstract
From 1970 to 1999, 44 patients with synovial sarcoma were seen at the University of Iowa. Tumor size was > or = 5 cm in 24 (55%). Histologic classification was biphasic in 26 (59%) and monophasic in 18 (41%). Seven patients (16%) had distant metastasis at initial presentation. For the 37 nonmetastatic patients, local treatment consisted of wide local excision in 29 and amputation in 8; chemotherapy was administered to 10. For the 29 who underwent wide local excision, microscopic resection margins were negative in 18 and positive in 11; 19 received postoperative radiotherapy. The 5-, 10-, and 20-year overall survival rates for the nonmetastatic group were 65.6%, 45.5%, and 37.8%. On multivariate analysis using age as a continuous covariate, younger age (p = 0.028), biphasic histology (p = 0.014), and extremity sites treated with limb-sparing surgery (p = 0.001) were found to be predictors of a better overall survival. No local failures were found after 5 years from initial diagnosis. On multivariate analysis, tumor location at an extremity site was the only variable marginally found to have a better local control (p = 0.065). Of the 19 patients who developed distant metastasis, 5 (26%) failed >5 years and 2 (11%) failed >15 years of follow-up. Younger age, biphasic histology, and extremity sites were found to have a better survival outcome. Late distant relapses can occur with synovial sarcoma.

Abstract
Soft-tissue tumors in children (<18 years) are a heterogeneous group of lesions. Masses may be asymptomatic or associated with pain or discomfort. Although most lesions are benign, developing an appropriate differential diagnosis requires knowledge of the clinical and radiographic characteristics of tumors and tumorlike conditions in children. A thorough history and physical examination, followed by appropriate imaging studies, when indicated, can establish a correct diagnosis and help determine appropriate treatment recommendations.

Abstract
Many of the soft tissue sarcomas that occur in children are of the same histology as those in adults; however, the relative prevalence of these sarcomas is different between children and adults. In some cases, the biologic behavior of pediatric sarcomas is more benign than that in adults. Treatment for sarcomas in children is also different. Pediatric sarcomas are more commonly responsive to chemotherapy. Furthermore, in children who are still growing, surgery and radiation are associated with higher morbidity than in adults. This article discusses the diagnosis and treatment of rhabdomyosarcoma and undifferentiated sarcomas, with an emphasis on surgical considerations, and the diagnosis and treatment of nonrhabdomyosarcomatous soft tissue sarcomas in children.

Abstract
Synovial sarcoma is the most common nonrhabdomyosarcomatous soft tissue sarcoma in children and adolescents and is characterized by a reciprocal t(X;18)(p11;q11) which results in the fusion of the SYT gene on chromosome 18q11 to either of two closely related genes, SSX1 (Xp11.23) or SSX2 (Xp11.21). Detection of this translocation or its resultant gene fusion by molecular methods is helpful in the pathologic diagnosis of synovial sarcoma, especially in poorly differentiated tumors. This study was designed to evaluate the utility of a real-time reverse transcriptase-polymerase chain reaction (RT-PCR) assay to detect and distinguish SYT-SSX1 and SYT-SSX2 fusions in fresh and archival specimens of synovial sarcoma in pediatric patients seen at St. Jude Children's Research Hospital. In addition, the clinicopathologic features of the tumors with SYT-SSX1 vs. SYT-SSX2 fusions were compared. The 25 patients studied had a median age of 13 years 9 months (range 5 to 19 years). Estimates of survival and event-free survival at 5 years were 78.7 +/- 10.5% and 56.2 +/- 13.2%, respectively. Seventeen (68%) tumors were monophasic, eight (32%) were biphasic. Seven tumors contained poorly differentiated areas. Positive results for either SYT-SSX1 or SYT-SSX2 were obtained in 21/25 (84%) cases. Three cases did not have a detectable gene fusion and one had no amplifiable RNA. SYT-SSX1 transcripts were found in 18/24 (75%) of the tumors while SYT-SSX2 transcripts were identified in 3/24 (12.5%). All of the poorly differentiated tumors and seven out of eight tumors from patients who developed lung metastases had an SYT-SSX1 fusion transcript. Real-time PCR is useful in detecting and distinguishing SYT-SSX1 from SYT-SSX2 gene fusions in synovial sarcoma. Valuable aspects of this methodology are the applicability to both frozen and formalin-fixed samples, decreased labor costs, and the rapidity of results. In addition, distinguishing SYT-SSX1 from SYT-SSX2 fusions with these methods allow for prospective collection of information that may clarify issues of prognostic relevance.

Abstract
Eighty-six children to 18 years of age were treated for nonrhabdomyosarcoma soft tissue sarcomas of the trunk and extremities. Synovial sarcoma (31), fibrosarcoma (13), malignant fibrous histiocytoma (11), epithelioid sarcoma (10), and clear cell sarcoma (7) were the most common diagnoses. Four patients presented with metastatic disease. A high percentage of patients presented after biopsy by the referring physician, although this could not be shown to affect outcome. Patients were treated with wide removal of the tumor when possible, with judicious use of adjuvant radiation, or with chemotherapy in selected cases. Mean followup was 11 years. Five- and 10-year survival was 92% and 84%, respectively. Tumors larger than 5 cm were associated with a worse prognosis. When compared with published data in adults, the prognosis of primary, localized nonrhabdomyosarcoma soft tissue sarcomas in children appears to be more favorable.

Abstract
Forty-three children with nonrhabdomyosarcomatous soft tissue sarcomas (NRSTS) were treated at the Northern Israel Oncology Center in Haifa, Israel, from 1971 to 1996. The male:female ratio was 1.5:1 and the median age of patient was 10 years (range, 3 months-18 years). The most common histopathologic diagnoses were fibrosarcoma (32.5%) and synovial sarcoma (16%). The sites of primary tumor were lower limb (35%), trunk (18%), upper limb (16%), head and neck (16%), and retroperitoneum (11%). By Intergroup Rhabdomyosarcoma Study classifications, 13 patients presented as group I, 15 patients as group II, 10 patients as group III, and 5 patients as group IV. Median follow-up time was 63 months (range, 6 months-18 years). The estimated survival after a 5-year period is 72% (SE +/- 17) for patients in group I, 75 +/- 15% in group II, 90 +/- 9% for patients in group III, and 40 +/- 21% for patients in group IV. Eleven patients relapsed; 4/6 who developed local relapse were cured and are alive with disease, while 4/5 who developed distant metastases are dead. For the 28 patients who underwent complete resection at diagnosis, the estimated survival after a 5-year period is 87 +/- 5% vs. 60 +/- 17% for the 15 patients who underwent partial excision or biopsy. Local radiotherapy was delivered after surgery to group III patients. Preoperative and postoperative chemotherapy was delivered to the patients of groups III and IV, and postoperative chemotherapy only to group II patients. Chemotherapy produced demonstrable gain in survival for group II and III patients but not for patients with metastases. The authors conclude that an aggressive surgical approach is needed in patients with NRSTS. Chemotherapy may help as a preoperative treatment in bulky disease or as a postoperative treatment for microscopic residual disease.

Abstract
BACKGROUND Because the natural history of pediatric patients with metastatic nonrhabdomyosarcomatous soft-tissue sarcomas (NRSTS) had not been well described, we retrospectively reviewed our single-institution experience with these tumors. PROCEDURE We identified 26 patients with metastatic NRSTS who were treated at St. Jude Children's Research Hospital from December 1971 through July 1995. We evaluated the characteristics of each patient, including age, sex, primary site, stage, type of therapy received, and outcome. Sites of metastatic disease at diagnosis and relapse were noted. RESULTS The median age of the 26 study patients at diagnosis was 14. 8 years; 54% of patients were male and 69% were white. The most common histologies were synovial sarcoma, alveolar soft-part sarcoma, and malignant fibrous histiocytoma. Most primary tumors (73% of cases) occurred in the trunk or extremities. Most patients presented with large (>5 cm), high-grade lesions. All 26 patients received chemotherapy, and 8 responded to an ifosfamide- or cyclophosphamide-doxorubicin-based regimen. Radiotherapy was administered to 15 patients, and 13 had a partial or complete resection of the primary tumor. Six patients underwent thoracotomy. The estimated 2-year survival for the cohort was 34.6% +/- 8.9%; the 2-year progression-free survival was 15.4% +/- 6.3%. The lung was the most common site of failure. CONCLUSIONS Children with metastatic NRSTS have a poor outcome, which is similar to that in adults. More effective systemic chemotherapy is needed to facilitate complete surgical resection of primary and metastatic sites. Aggressive pulmonary metastatectomy can increase disease control.

Abstract
Lipoblastomas are most commonly superficially-located tumors. Our experience with three examples of deep-seated lipoblastomas is reported. The CT scans of all cases showed low-attenuation densities (less than 0 Hansfield units), strongly suggesting fatty composition. Fine-needle aspiration biopsy (FNAB) smears contained uni- and multivacuolated lipoblasts, myxoid areas, and a plexiform capillary network. The combination of CT scan and FNAB findings seems to be enough for definitive preoperative diagnosis of lipoblastoma, allowing differential diagnosis with other deep-seated tumors.

Abstract
BACKGROUND The role of postoperative radiotherapy and adjuvant chemotherapy in the treatment of synovial sarcoma remains to be determined. PROCEDURE Twenty-five children were treated during a 23-year period with a multimodality approach. All of them had resection of the primary tumor (three amputations), followed by surgical retreatment in eight. Postoperative radiotherapy was delivered to 16 patients and adjuvant chemotherapy was given to 22. RESULTS At the time of the report, 19 patients were alive and without evidence of disease. Six developed distant metastases (one associated with local recurrence); five of them died of their disease and one was alive in complete remission at 4 years from relapse. With a median follow-up of 9 years (range 2-23), the survival and the event-free survival at 5 years were 80% (SE 8.2) and 74% (SE 9.2), respectively. All relapsing patients had been classified as T2B. CONCLUSIONS Multimodality treatment yielded satisfying survival results using limb-preserving surgery in most cases. Tumor size > 5 cm and invasiveness, which defined stage T2B, were the most important predictors of poor outcome. Evaluation of the role of adjuvant chemotherapy and radiotherapy awaits prospective studies, even if T2B patients, as well as children having nonradical surgery, seem worth managing by adjuvant treatments.

Abstract
Rhabdomyosarcoma is the most common primary orbital malignancy of childhood. It can present insidiously, mimicking other (benign) processes clinically and radiographically. CT and MR imaging are crucial in the diagnostic evaluation, treatment planning, and follow-up monitoring of the disease. Such imaging, especially when contrast is used, can accurately detect and state the extent of tumor involvement.

Abstract
BACKGROUND The objectives of this study were to compare vincristine/actinomycin D/cyclophosphamide/adriamycin (VACA) with VACA/plus imidazole carboxamide (DTIC) (VACAD) therapy in regards to complete/partial response and event free survival rates in children and adolescents with metastatic non-rhabdomyosarcoma soft tissue sarcomas (NRSTS) or previously chemotherapy-naive recurrent NRSTS or locally persistent gross residual tumor after surgery and radiation therapy. PROCEDURES Between 1986 and March 1994, 75 patients entered this randomized study comparing VACA and VACAD, given at 3 week intervals. Sixty-one patients were considered eligible and received chemotherapy and radiation therapy to the primary tumor and areas of metastases. Thirty-six patients had regional unresected (Group III) disease, and 25 had metastatic disease (Group IV) at time of accession. Thirty-six patients received VACA (11 were not randomized), and 25 received VACAD. RESULTS With a median follow-up of greater than 4 years, overall and event-free survival for all eligible patients are 30.6% and 18.4% respectively (S.E: 9.5% and 6.8%). There was insufficient evidence that DTIC offered any advantage to event free survival, but there was evidence for better outcome for patients in Group III disease in comparison to patients with Group IV disease, and for patients with a Grade 1 and 2 histology in comparison to Grade 3 lesions. CONCLUSIONS Combination chemotherapy with VACA and VACAD were insufficient to prevent recurrent or progressive disease in children and adolescents with high stage NRSTS. The use of vincristine/ifosfamide/doxorubicin with cytokine support is under study.

Abstract
BACKGROUND Standard therapy for pediatric nonrhabdomyosarcoma soft tissue sarcomas (PNRSTS) consists of surgical resection with or without radiotherapy. The role of chemotherapy in the treatment of these tumors has not yet been defined. We investigated the efficacy and toxicity of an ifosfamide-based regimen in controlling disease in children with high-risk PNRSTS. PATIENTS AND METHODS Between January 1992 and June 1994 at St. Jude Children's Research Hospital, we treated 11 children and young adults with PNRSTS who were at high risk for treatment failure by using a combined modality regimen that comprised aggressive surgery, radiotherapy, and chemotherapy including vincristine, ifosfamide, and doxorubicin (VID). Nine of these patients had grade 3 disease and one had grade 2 tumor; due to insufficient tissue, the disease grade of the remaining patient could not be established. Metastases were present at diagnosis in 2 children. RESULTS Therapy was generally well tolerated, with minimal morbidity and no mortality. The most common toxicity was grade 4 neutropenia, which occurred in 51% of evaluable courses. Among 4 patients evaluable for response to chemotherapy alone, 1 child attained a partial response and 3 had stable disease. One child had a response to chemotherapy and concurrent irradiation. At a median follow-up of 30 months, 10 of 11 patients are alive; 8 of 11 patients are alive without evidence of disease. CONCLUSION Aggressive multimodality therapy for PNRSTS is well tolerated, despite frequent and profound neutropenia. Although adjuvant chemotherapy for this group of cancers remains unproved, the rate of tumor control achieved in this pilot study encourages further investigation in a multi-institutional setting.

Abstract
Soft tissue sarcomas (STS) arising in the foot are rare in children. From 1975 to 1994, 18 children (median age, 13.5 years) were treated at St Jude Children's Research Hospital for STS of the foot. Five children had rhabdomyosarcoma (RMS), with alveolar histology in four cases. All of these patients presented with metastatic disease, which proved fatal within 9 to 24 months despite combined modality treatment with chemotherapy, radiation, and surgery. Thirteen patients had nonrhabdomyosarcoma soft tissue sarcoma (NRSTS). The most common histological variant was synovial sarcoma (7 patients). Of the 10 who presented with localized disease, seven survived 1 to 12 years (median, 7 years). Surgical treatment for these consisted of local excision (n = 2), wide local excision (n = 3), below knee amputation (n = 1 ), ray amputation (n = 1). Three received supplemental radiation, and one was also treated with chemotherapy. Local or distant recurrence proved fatal in the three other children who had localized disease. Three children who presented with metastatic NRSTS died 8 to 14 months after diagnosis. All surviving patients are without significant functional disability. In our experience, pediatric RMS of the foot has a poor outcome, attributable to both alveolar histology and presence of metastatic disease at diagnosis. In contrast, NRSTS of the foot is more often localized, and limited surgery with adjuvant radiation in the absence of clear margins should be the treatment of choice.

Abstract
Cytogenetic and molecular genetic studies were performed on a pleomorphic sarcoma removed from the left atrium of a 15-year-old girl. Histologic analysis was consistent with a storiform-pleomorphic malignant fibrous histiocytoma (MFH). Although MFH is the most common soft-tissue sarcoma of late adulthood. It is extremely rare in childhood and its existence in the pediatric population remains controversial. Cytogenetic analysis revealed several alterations previously associated with adult MFH, including abnormalities of chromosomal bands 11p11 and 19p13. Moreover, the tumor demonstrated homogeneously staining regions (HSR) and double minute chromosomes (dmin) suggestive of gene amplification. We therefore screened the case for amplification of genes localized to chromosomal bands 12q13-14, including the putative protooncogenes MDM2, CDK4, SAS, CHOP, and CLI, which are frequently amplified and overexpressed in adult MFH. Southern and Northern blot analysis confirmed the coamplification of MDM2, CDK4, SAS, and CHOP. To our knowledge, such coamplification studies of the 12q13-14 amplicon have not been previously detected in pediatric MFH. Our results provide cytogenetic and molecular genetic evidence that pediatric and adult MFH are histogenetically related entities.

Abstract
Because malignant fibrous histiocytoma (MFH) rarely occurs in children, the natural history of this tumor and prognostic factors predictive of outcome have not been well described. The charts of all pediatric patients with MFH seen at M.D. Anderson Cancer Center were reviewed with respect presentation, treatment, and outcome, in an attempt to determine prognostic factors that are predictive of survival. Forty-four pediatric patients were identified. Extremities were the most common tumor site (31 of 44 patients). Five patients presented with angiomatoid histology subtype; all subsequently survived. The estimated 5-year survival rate was 85% for clinical group I patients, 87% for clinical group II, 53% for clinical group III, and 0% for clinical group IV. The estimated 5-year survival rate was 95% for patients with tumors of less than 5 cm in diameter and 45% for those with larger tumors. Overall, the estimated 5-year survival rate was 71%. Significant prognostic factors found to affect survival (by univariate analysis) were clinical group, tumor size, and recurrence. Gender and race were not significant predictors. The use of chemotherapy and radiation was not found to improve the chance of survival, but this most likely reflected the more frequent use of adjuvant therapy in patients with unresectable or high-grade tumors. Although adequate surgical resection continues to be the most effective treatment, investigation of adjuvant chemotherapy and radiation therapy on protocol is warranted.

Abstract
The role of irradiation in the management of synovial sarcoma (SS) in pediatric patients is evaluated. The review covers all children seen at St. Jude Children's Research Hospital between May 1969 and December 1992 with the diagnosis of soft tissue sarcoma, of the 37 patients with the subtype SS, 16 received irradiation for the management of primary site disease. There were four IRS Group I, six Group II, four Group III, and two Group IV patients receiving irradiation. Tumor grade included seven Grade II, and nine Grade III lesions. TMN staging identified eight T1 and eight T2 lesions. Follow-up has ranged from 14 to 117 months (med = 33 months). All IRS Group I patients had documented local control. Five of six IRS Group II and 4/4 Group III patients have had documented local control at last follow-up. IRS Group IV patients had either local control tumor stabilization (n=1) or evidence of tumor regression (n=1) at autopsy. Complications following irradiation include wound dehiscence (n=1), surgery to revise a painful scar (n=1) extremity length discrepancy (n=2), and femoral head avascular necrosis (n=1). At last follow-up, 10 of 14 patients receiving curative intent irradiation remain alive. This review indicates questionable benefit to the addition of irradiation for patients with adequate surgical resection and having "good" tumor characteristics (Grade I, II; IRS Group I, TMN T1A,T1B. For lesions that have had incomplete resection or partial response to chemotherapy, there is evidence that irradiation may provide durable local control. The role of irradiation in those patients with IRS Group IV disease is at present confined to palliative roles until the time when more effective chemotherapy will mandate the decision to treat primary disease for curative measures.

Abstract
BACKGROUND The experience of one institution in treating soft tissue sarcomas of the head and neck in a pediatric population is presented. METHODS Case materials of 134 patients younger than 20 years who were referred to the University of Texas M. D. Anderson Cancer Center between 1970 and 1989 for treatment of sarcoma of the head and neck were retrospectively reviewed. Patients with rhabdomyosarcoma underwent multimodality treatment consisting of surgery, irradiation, and chemotherapy. Wide resection was the treatment used for patients with nonrhabdomyosarcomatous soft tissue sarcomas (NRSTS). Adjuvant chemotherapy and irradiation were used to treat high grade neoplasms and residual disease. The clinical response to therapy was measured in terms of the disease-specific survival rate. RESULTS Seventy-nine of 134 patients presented with untreated or biopsy-proven disease. Fifty-six had rhabdomyosarcoma and 23 had NRSTS At 2 and 5 years, the disease-specific survival rates for patients with rhabdomyosarcoma were 74% and 63%, respectively, and patients with NRSTS had 80% and 75% disease-specific survival rates at 2 and 5 years, respectively. CONCLUSIONS Rhabdomyosarcoma of the head and neck in children is effectively treated with multimodality therapy. Prognostic indicators for rhabdomyosarcoma include completeness of tumor resection and the development of recurrent disease. Aggressive surgical resection is the treatment of choice for patients with NRSTS Prognostic indicators for NRSTS include completeness of tumor resection and the development of recurrent disease.

Abstract
We have identified a distinctive malignant soft tissue neoplasm that occurred in the head and neck region of six children. Histologically, these neoplasms presented an array of features ranging from low-grade spindle cell to high-grade fibrohistiocytic histologies and often had myoid characteristics. Ultrastructural and immunohistochemical studies indicated that they contained neoplastic myofibroblasts that were variably positive for vimentin (4 positive/4 tested), alpha-smooth muscle actin (4/5), muscle-specific actin (5/5), desmin (2/5), and v-src protein substrate p80/85 (4/5). Three patients died of rapidly progressive unresectable local disease, one died of metastatic and local disease, and two are alive 13 months and 8 years after wide resection. We conclude that these neoplasms form a distinctive subset of pediatric soft tissue sarcomas that display an aggressive clinical behavior, typically with local recurrence, and exhibit features of myofibroblastic differentiation.

Abstract
Fluorescence in situ hybridization (FISH) and molecular analyses of synovial sarcomas with cytogenetically similar (X;18)(p11.2;q11.2) translocations have revealed two alternative breakpoint regions in Xp11.2, one residing in the ornithine aminotransferase-like 1 (OATL1) region and the other one in the related but distinct OATL2 region. As these results were obtained by different groups, we set out to evaluate an extended series of tumors with special emphasis on the two possible X-related breakpoint regions. Together, seven synovial sarcomas were identified with a break in the OATL1 region and six with a break near OATL2, thereby confirming the actual existence of the two alternative Xp breakpoint regions. We speculate that there seems to be a relationship between the occurrence of these breakpoint regions and the histologic phenotype of the tumors, with a predominance of OATL1-related breakpoints in the classical biphasic tumors and of OATL2-related breakpoints in the monophasic fibrous tumors.
