Abstract
Skeletal muscle (SKM), despite comprising ~40% of body mass, rarely manifests cancer. This review explores the mechanisms that help to explain this rarity, including unique SKM architecture and function, which prohibits the development of new cancer as well as negates potential metastasis to SKM. SKM also presents a unique immune environment that may magnify the anti-tumorigenic effect. Moreover, the SKM microenvironment manifests characteristics such as decreased extracellular matrix stiffness and altered lactic acid, pH, and oxygen levels that may interfere with tumor development. SKM also secretes anti-tumorigenic myokines and other molecules. Collectively, these mechanisms help account for the rarity of SKM cancer.

Ann Med Surg (Lond) 2024; 86:472-476. [PMID: 38222709 PMCID: PMC10783232 DOI: 10.1097/ms9.0000000000001423] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Accepted: 10/09/2023] [Indexed: 01/16/2024] Open
Abstract
Introduction and importance Rhabdomyosarcoma is a malignant tumour that originates from immature muscle cells and belongs to the category of soft-tissue sarcomas. It is predominantly diagnosed in children under the age of 6. This condition can manifest within the genitourinary tract and may exhibit non-specific symptoms such as changes in bowel habits and fever. Early detection and a comprehensive, multidisciplinary approach are essential to achieving more favourable outcomes. This report highlights an uncommon case of urogenital rhabdomyosarcoma in a 15-year-old girl, in addition to the presence of a rectovaginal fistula. Case presentation A 15-year-old girl with presented with fever, altered bowel habits, and a lump in her lower abdomen, abdominal discomfort, and incomplete bowel evacuation. She also had faecal discharge from the vagina. Diagnostic imaging and biopsy confirmed urogenital rhabdomyosarcoma with a rectovaginal fistula. The patient is currently undergoing induction chemotherapy and is scheduled for radiation therapy and surgery. Clinical discussion Rhabdomyosarcoma is a rare paediatric oncologic concern due to its aggressive nature and potential metastasis. The presentation varies based on age, tumour location, and metastasis presence. This patient presented with altered bowel habits, a pelvic mass and unusual feculent discharge, suggesting a rectovaginal fistula. Diagnostic imaging confirmed the diagnosis, and induction chemotherapy led to a positive response and reduced tumour size. Conclusion Urogenital rhabdomyosarcoma is an aggressive malignancy with non-specific symptoms, making early diagnosis challenging. An accurate diagnosis requires high suspicion, imaging, and a biopsy. Multidisciplinary management, including surgery, chemotherapy, and radiation therapy, improves outcomes and improves paediatric patients' prognosis and quality of life.

Abstract
Rhabdomyosarcoma is a rare cancer arising in skeletal muscle that typically impacts children and young adults. It is a worldwide challenge in child health as treatment outcomes for metastatic and recurrent disease still pose a major concern for both basic and clinical scientists. The treatment strategies for rhabdomyosarcoma include multi-agent chemotherapies after surgical resection with or without ionization radiotherapy. In this comprehensive review, we first provide a detailed clinical understanding of rhabdomyosarcoma including its classification and subtypes, diagnosis, and treatment strategies. Later, we focus on chemotherapy strategies for this childhood sarcoma and discuss the impact of three mechanisms that are involved in the chemotherapy response including apoptosis, macro-autophagy, and the unfolded protein response. Finally, we discuss in vivo mouse and zebrafish models and in vitro three-dimensional bioengineering models of rhabdomyosarcoma to screen future therapeutic approaches and promote muscle regeneration.

Abstract
This study aimed to analyze burden of STS and GIST in population and survival rate which represented the current situation of treatment in Thailand. The data was collected from five population-based cancer registries around the country for the period 2001 through 2015. The Segi world standard population was used to calculated age-standardized incidence rates (ASR). Standardized rate ratios (SRR) were used to compare populations. Joinpoint Trend Analysis was used to assess changes in incidence. STATA was used to examine patient survival rates. During the study period, 4080 cases of STS and 457 cases of GIST were reported. The ASR of STS and GIST was 2.14/100,000 person-years and 0.22/100,000 person-years, respectively. The most common histological types of STS were unspecified sarcoma (24.8%), leiomyosarcoma (19.0%) and liposarcoma (11.4%). The overall ASR of STS in Thailand was relatively low compared to Western countries. The five-year survival rate was 62.6% for STS and 63.4% for GIST, which was comparable to the rates reported in other countries. This is the first report of STS and GIST from PBCRs in Thailand. Based on current healthcare service, an overall survival rates of STS and GIST are comparable to those reported from others.

Abstract
Simple Summary This review provides an overview of clinical features and current therapies in children, adolescents, and young adults (AYA) with sarcoma. It highlights the basic and clinical findings on the cyclin-dependent kinases 4 and 6 (CDK4/6) cell cycle regulatory pathway in the context of the precision medicine-based molecular profiles of the three most common types of pediatric and AYA sarcomas—osteosarcoma (OS), rhabdomyosarcoma (RMS), and Ewing sarcoma (EWS). Abstract Despite improved therapeutic and clinical outcomes for patients with localized diseases, outcomes for pediatric and AYA sarcoma patients with high-grade or aggressive disease are still relatively poor. With advancements in next generation sequencing (NGS), precision medicine now provides a strategy to improve outcomes in patients with aggressive disease by identifying biomarkers of therapeutic sensitivity or resistance. The integration of NGS into clinical decision making not only increases the accuracy of diagnosis and prognosis, but also has the potential to identify effective and less toxic therapies for pediatric and AYA sarcomas. Genome and transcriptome profiling have detected dysregulation of the CDK4/6 cell cycle regulatory pathway in subpopulations of pediatric and AYA OS, RMS, and EWS. In these patients, the inhibition of CDK4/6 represents a promising precision medicine-guided therapy. There is a critical need, however, to identify novel and promising combination therapies to fight the development of resistance to CDK4/6 inhibition. In this review, we offer rationale and perspective on the promise and challenges of this therapeutic approach.

Abstract
Background There are hereditary types of nephroblastoma or Wilms’ tumor associated with exposure of the germ cells of either parent to harmful environmental factors. Some studies have examined the exposure of compounds used pesticides and herbicides as a risk factor for Wilms’ tumor. Methods A systematic review and meta-analysis were carried out on case-control studies to establish the potential link between exposure to these organic molecules and Wilms’ tumor occurrence in children rigorously. We examined the monographs on some organo-phosphate insecticides and herbicides issued by the International Association for the Research on Cancer (IARC) under the auspices of the World Health Organization (WHO). PUBMED, SCOPUS, and Google Scholar studies (1960–2021) were identified and systematically reviewed following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Subgroup analyses were conducted after stratification for occupational versus residential exposure and before birth (prenatal) vs. after birth (postnatal) exposure. In addition, we revised the monographs on chemical compounds issued recently by the IARC/WHO. Results Our findings seem to consolidate that parental pesticide exposure during the preconception or pregnancy period is correlated with an increased occurrence risk for Wilms’ tumor. We confirm the validity of the WHO essays on certain organophosphate herbicides and insecticides, which support these compounds, may be highly relevant in future cancer prevention policies. Conclusion Parental exposure to pesticides, particularly in household settings, is poorly emphasized in our society. There is a strong association between these organophosphate compounds and pediatric cancer. Public health agencies may need to take stronger action than in the past.

Characteristics of Nephroblastoma/Nephroblastomatosis in Children with a Clinically Reported Underlying Malformation or Cancer Predisposition Syndrome. Cancers (Basel) 2021; 13:cancers13195016.

Abstract
Simple Summary It is well known that different cancer predisposition syndromes are associated with characteristic WT-features. The following findings from our retrospective analysis of patients with nephroblastoma treated according to the SIOP/GPOH trials between 1989 and 2017 are relevant: (1) The outcome of patients with a cancer predisposition syndrome is not always favorable despite early diagnosis, small tumors and less metastatic disease. This finding is partly depending on complications related to the underlying syndrome. (2) Predisposition syndromes seem to be underdiagnosed as several clinical and pathological features of Wilms tumor being clearly linked to a cancer predisposition syndrome did not lead to genetic counseling before and after WT diagnosis. As a conclusion, in children with a nephroblastoma and specific clinical and pathological features that are in line with a nephroblastoma cancer predisposition syndrome such a syndrome should always be considered and ruled out if unknown at the time of tumor diagnosis. Abstract (1) Background: about 10% of Wilms Tumor (WT) patients have a malformation or cancer predisposition syndrome (CPS) with causative germline genetic or epigenetic variants. Knowledge on CPS is essential for genetic counselling. (2) Methods: this retrospective analysis focused on 2927 consecutive patients with WTs registered between 1989 and 2017 in the SIOP/GPOH studies. (3) Results: Genitourinary malformations (GU, N = 66, 2.3%), Beckwith-Wiedemann spectrum (BWS, N = 32, 1.1%), isolated hemihypertrophy (IHH, N = 29, 1.0%), Denys-Drash syndrome (DDS, N = 24, 0.8%) and WAGR syndrome (N = 20, 0.7%) were reported most frequently. Compared to others, these patients were younger at WT diagnosis (median age 24.5 months vs. 39.0 months), had smaller tumors (349.4 mL vs. 487.5 mL), less often metastasis (8.2% vs. 18%), but more often nephroblastomatosis (12.9% vs. 1.9%). WT with IHH was associated with blastemal WT and DDS with stromal subtype. Bilateral WTs were common in WAGR (30%), DDS (29%) and BWS (31%). Chemotherapy induced reduction in tumor volume was poor in DDS (0.4% increase) and favorable in BWS (86.9% reduction). The event-free survival (EFS) of patients with BWS was significantly (p = 0.002) worse than in others. (4) Conclusions: CPS should be considered in WTs with specific clinical features resulting in referral to a geneticist. Their outcome was not always favorable.

Abstract
Rhabdomyosarcoma (RMS) is the most frequent soft tissue sarcoma (STS) in children and adolescents. In Spain the annual incidence is 4.4 cases per million children < 14 years. It is an uncommon neoplasm in adults, but 40% of RMS are diagnosed in patients over 20 years of age, representing 1% of all STS in this age group. RMS can appear anywhere in the body, with some sites more frequently affected including head and neck, genitourinary system and limbs. Assessment of a patient with suspicion of RMS includes imaging studies (MRI, CT, PET-CT) and biopsy. All patients with RMS should receive chemotherapy, either at diagnosis in advanced or metastatic stages, or after initial resection in early local stages. Local control includes surgery and/or radiotherapy depending on site, stage, histology and response to chemotherapy. This guide provides recommendations for diagnosis, staging and treatment of this neoplasm.

Abstract
Temporal bone rhabdomyosarcoma is an aggressive entity that simulates chronic otitis ear infection. It is the most common soft tissue sarcoma amongst pediatric patients. Herein, we would like to report a case of temporal bone rhabdomyosarcoma involving a 2-year-old boy who presented with a one-month history of otorrhea with facial asymmetry. Early treatment led to remission of this severe neoplasm.

Abstract
Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in children and represents a high-grade neoplasm of skeletal myoblast-like cells. Decades of clinical and basic research have gradually improved our understanding of the pathophysiology of RMS and helped to optimize clinical care. The two major subtypes of RMS, originally characterized on the basis of light microscopic features, are driven by fundamentally different molecular mechanisms and pose distinct clinical challenges. Curative therapy depends on control of the primary tumour, which can arise at many distinct anatomical sites, as well as controlling disseminated disease that is known or assumed to be present in every case. Sophisticated risk stratification for children with RMS incorporates various clinical, pathological and molecular features, and that information is used to guide the application of multifaceted therapy. Such therapy has historically included cytotoxic chemotherapy as well as surgery, ionizing radiation or both. This Primer describes our current understanding of RMS epidemiology, disease susceptibility factors, disease mechanisms and elements of clinical care, including diagnostics, risk-based care of newly diagnosed and relapsed disease and the prevention and management of late effects in survivors. We also outline potential opportunities to further translate new biological insights into improved clinical outcomes.

Abstract
Measurement of incidence rates of childhood cancer in Africa is difficult. The study 'Cancer of Childhood in sub Saharan Africa' brings together results from 16 population-based registries which, as members of the African Cancer Registry Network (AFCRN), have been evaluated as achieving adequate coverage of their target population. The cancers are classified according to the third revision of the International Classification of Childhood Cancer (ICCC-3) and recorded rates in Africa are compared with those in childhood populations in the UK, France, and the USA. It is clear that, in many centres, lack of adequate diagnostic and treatment facilities leads to under-diagnosis (and enumeration) of leukaemias and brain cancers. However, for several childhood cancers, incidence rates in Africa are higher than those in high-income countries. This applies to infection-related cancers such as Kaposi sarcoma, Burkitt lymphoma, Hodgkin lymphoma and hepatocellular carcinoma, and also to two common embryonal cancers - retinoblastoma and nephroblastoma. These (and other) observations are unlikely to be artefact, and are of considerable interest when considering possible aetiological factors, including ethnic differences in risk (and hence genetic/familial antecedents). The data reported are the most extensive so far available on the incidence of cancer in sub Saharan Africa, and clearly indicate the need for more resources to be devoted to cancer registration, especially in the childhood age range, as part of an overall programme to improve the availability of diagnosis and treatment of this group of cancers, many of which have-potentially-an excellent prognosis.

Abstract
Recent methodology has enabled the identification of some new genetic subgroups within the melting pot of lesions presently classified by the 2013 WHO classification as "undifferentiated/unclassified sarcomas". One of these subgroups is characterized by a paracentric inversion of the X chromosome with consequent formation of a BCOR-CCNB3 fusion. Clinical and pathological features of these tumors overlap with the Ewing sarcoma family as well as other soft tissue sarcomas, thus making them difficult to diagnose. To investigate the morphological and immunohistochemical characteristics of BCOR-CCNB3 positive sarcoma, we reviewed two sarcoma series, comprising 632 and 121 cases. The 11 tumors harboring the BCOR-CCNB3 fusion, identified by CCNB3 immunohistochemistry and/or RT-PCR, were reevaluated for morphological characteristics and further immunohistochemical investigations for CCNB3, SATB2, and Pax8 were performed. Tumors harboring a BCOR-CCNB3 fusion (11/753) occured exclusively in males, with a mean age at diagnosis of 12.9 years, and were mainly axially located. In this group of either spindled or round cell tumors, vesicular nuclei with finely dispersed chromatin, inconspicuous nucleoli and an arciform vascular pattern were pathognomonic. More than 50% of cases stained positive for SATB2 and Pax8, raising the hypothesis of a potential use of these markers in the identification of BCOR-CCNB3 positive undifferentiated/unclassified sarcomas. CCNB3 was confirmed as a useful ancillary immunohistochemical marker.

Abstract
A total of 75 children with biopsy-proven rhabdomyosarcoma were treated at our institution between 1990 and 2010. Five-year overall survival (OS) for the entire cohort was 58.7%. OS by stage was as follows: Stage 1 (80%), Stage 2 (80%), Stage 3 (54.1%), and Stage 4 (38.5%). There was a trend to suggest that revision of treatment approaches improved crude survival over time: pre-2003 (OS 42.1%); 2003-2005 (OS 50.0%); 2005-2010 (OS 60.8%).

Abstract
BACKGROUND Cancer is an important cause of morbidity and mortality worldwide in children under 15 years of age, with the incidence and mortality rate varying from 40 to 155 per million children. AIM To describe the pattern of childhood cancer in Ibadan, Nigeria. OBJECTIVE To compare the findings of this study with those of previous studies in Ibadan and internationally. METHODS A retrospective review of histologically and cytologically confirmed cases of cancer in children aged <15 years diagnosed at University College Hospital (UCH), Ibadan between January 1991 and December 2010 was undertaken. The cases were categorised using the International Classification of Childhood Cancer, third edition (ICCC-3). RESULTS There were 625 cases comprising 360 (57·6%) males with a modal age of 3 years. The most common neoplasms were lymphomas (140, 22·4%), of which 90% were non-Hodgkin lymphomas, with Burkitt lymphoma constituting the majority of cases (73). Other common neoplasms were retinoblastomas (21%), soft tissue sarcomas (14·9%), leukaemias (10·2%) and CNS tumours (6·9%). Lymphomas, bone tumours, malignant hepatic tumours and other malignant epithelial neoplasms had the highest mean and modal ages, while retinoblastomas, neuroblastomas, germ cell tumours and renal tumours had the lowest mean and modal ages. During 1960-72 there were 1326 cases and during 1973-90 there were 1881 cases and the proportion of lymphomas was 58·9% and 45·4%, respectively. The present study demonstrated a marked decline in the number of cases and proportion of lymphomas (22·4%), particularly Burkitt lymphomas. CONCLUSION During the last 20 years, there has been a decline in the number of cases of childhood cancer seen at UCH, Ibadan. This may be due to the establishment of additional specialist centres in the sub-region. Owing to a persistent decline in the frequency of Burkitt lymphoma, retinoblastoma is now the most common individual childhood cancer seen at Ibadan.

Abstract
Fibrosarcoma belongs to the sarcoma cancer group, which are spindle cell malignancies of mesenchymal origin, and owe their name to the predominant cell line that is present within the tumor. The extracellular matrix (ECM) is a complicated structure that surrounds and supports cells within tissues. Its main components are proteoglycans, collagens, glycoproteins, hyaluronan (HA), and several matrix-degrading enzymes. During cancer progression, significant changes can be observed in the structural and mechanical properties of ECM components. The ECM provides a physical scaffold to which tumor cells attach and migrate. Thus, it is required for key cellular events such as cell motility, adhesion, proliferation, invasion, and metastasis. Importantly, fibrosarcomas were shown to have a high content and turnover of ECM components including HA, proteoglycans, collagens, fibronectin, and laminin. In this review, we will focus on the HA component of fibrosarcoma ECM and critically discuss its role and involved mechanisms during fibrosarcoma pathogenesis.

Abstract
OBJECTIVE We report on the incidence and the gender, age, and ethnic distribution of sarcomas diagnosed between 1980 and 2008 in the multi-ethnic Republic of Suriname. METHODS Total and average yearly number of cases, crude rates, as well as relevant population data were derived from the records of the Pathologic Anatomy Laboratory and the General Bureau of Statistics, respectively, and stratified according to gender, age groups 0-19, 20-49 and 50+ years, and the largest ethnic groups (Hindustani, Creole, Javanese and Maroons). RESULTS Between 1980 and 2008, 258 sarcomas were diagnosed in Suriname, ie at a frequency of nine per year and an annual rate of two per 100 000. Overall, there was 0.9 male per female, two to four cases per year in each age group, and one to three patients in each ethnic group. Soft-tissue sarcomas comprised approximately 80% of overall cases, with a male/female ratio that was approximately 0.5; almost 90% of patients were older than 20 years; more than one-third was Creole. Leiomyosarcoma, fibrosarcoma and liposarcoma were most frequently encountered (90 cases), particularly above 20 years of age, while leiomyosarcomas seemed, additionally, more common in women and Creoles or Maroons. The most numerous bone tumours were primitive neuroectodermal tumour/Ewing tumour and osteosarcoma (37 cases). They were more common in males, the youngest age group, and Hindustanis and Creoles. CONCLUSIONS The incidence of sarcomas in Suriname, and their gender, age and ethnic distribution in general, seemed comparable with international data. The main exception might be leiomyosarcoma which might have a predilection for Afro-Surinamese.

Abstract
Fibrosarcomas are rare malignant mesenchymal tumors originating from fibroblasts. Importantly, fibrosarcoma cells were shown to have a high content and turnover of extracellular matrix (ECM) components including hyaluronan (HA), proteoglycans, collagens, fibronectin, and laminin. ECMs are complicated structures that surround and support cells within tissues. During cancer progression, significant changes can be observed in the structural and mechanical properties of the ECM components. Importantly, hyaluronan deposition is usually higher in malignant tumors as compared to benign tissues, predicting tumor progression in some tumor types. Furthermore, activated stromal cells are able to produce tissue structure rich in hyaluronan in order to promote tumor growth. Key biological roles of HA result from its interactions with its specific CD44 and RHAMM (receptor for HA-mediated motility) cell-surface receptors. HA-receptor downstream signaling pathways regulate in turn cellular processes implicated in tumorigenesis. Growth factors, including PDGF-BB, TGFβ2, and FGF-2, enhanced hyaluronan deposition to ECM and modulated HA-receptor expression in fibrosarcoma cells. Indeed, FGF-2 through upregulation of specific HAS isoforms and hyaluronan synthesis regulated secretion and net hyaluronan deposition to the fibrosarcoma pericellular matrix modulating these cells' migration capability. In this paper we discuss the involvement of hyaluronan/RHAMM/CD44 mediated signaling in the insidious pathways of fibrosarcoma progression.

Abstract
We searched for a drug capable of sensitization of sarcoma cells to doxorubicin (DOX). We report that the dual PI3K/mTOR inhibitor PI103 enhances the efficacy of DOX in several sarcoma cell lines and interacts with DOX in the induction of apoptosis. PI103 decreased the expression of MDR1 and MRP1, which resulted in DOX accumulation. However, the enhancement of DOX-induced apoptosis was unrelated to DOX accumulation. Neither did it involve inhibition of mTOR. Instead, the combination treatment of DOX plus PI103 activated Bax, the mitochondrial apoptosis pathway, and caspase 3. Caspase 3 activation was also observed in xenografts of sarcoma cells in nude mice upon combination of DOX with the specific PI3K inhibitor GDC-0941. Although the increase in apoptosis did not further impact on tumor growth when compared to the efficient growth inhibition by GDC-0941 alone, these findings suggest that inhibition of PI3K may improve DOX-induced proapoptotic effects in sarcoma. Taken together with similar recent studies of neuroblastoma- and glioblastoma-derived cells, PI3K inhibition seems to be a more general option to sensitize tumor cells to anthracyclines.

Sixty-eight cases of STS were registered from 2000 to 2009. Crude incidence rate was 0,78, and age-standardized incidence rate using World Standard Population was 0,81 per 100.000 children/year. The highest age-specific incidence was observed in infants: 1,76 per 100.000 children/year. Rhabdomyosarcoma (RMS) was the most common histological type comprising 54,4% of all STS. 5-year observed survival (OS) of all patients with STS was 64,1 (95% CI 55,0-73,2). There was no statistically significant difference in OS between RMS-59,2 (95% CI 47,0-71,4) and nonrhabdomyosarcoma STS-69,3 (95% CI 55,8-82,8) (P = 0.63). Incidence and survival rates of STS observed in the study were comparable to the other Eastern European countries.

Abstract
Introduction. Malignant peripheral nerve sheath tumors (MPNSTs) are rare, aggressive soft tissue sarcomas associated with poor prognosis, that most commonly affect patients aged 20 to 50 years, but have also been reported in children. There is little reported in literature on these tumors in Africa. Materials and Methods. A search of the hospital pathology database between 1992 and 2008 revealed 333 nerve sheath tumors, of which 31 were MPNSTs. Four representative case reports are presented. Discussion. MNPSTs have rarely been reported from sub-Saharan Africa; in this study, they constituted 9.3% of all nerve sheath tumors. The trunk (42%) and limbs (45%) were the most frequently affected anatomical sites. Late presentation of malignant lesions in this environment is exemplified by the four case presentations patients. Conclusions. This report confirms observations from studies on MPNSTs from other environments. Anatomically centrally located MPNSTs may have a higher incidence in sub-Saharan Africa than in the West. Because NF1-associated MPNSTs are difficult to diagnose clinically, and because surgery is the only mode of therapy that offers a complete cure, a lifetime follow-up is important, as this would enable diagnosis of early lesions amenable to surgical extirpation.

Abstract
Background The exact overall incidence of sarcoma and sarcoma subtypes is not known. The objective of the present population-based study was to determine this incidence in a European region (Rhone-Alpes) of six million inhabitants, based on a central pathological review of the cases. Methodology/Principal Findings From March 2005 to February 2007, pathology reports and tumor blocks were prospectively collected from the 158 pathologists of the Rhone-Alpes region. All diagnosed or suspected cases of sarcoma were collected, reviewed centrally, examined for molecular alterations and classified according to the 2002 World Health Organization classification. Of the 1287 patients screened during the study period, 748 met the criteria for inclusion in the study. The overall crude and world age-standardized incidence rates were respectively 6.2 and 4.8 per 100,000/year. Incidence rates for soft tissue, visceral and bone sarcomas were respectively 3.6, 2.0 and 0.6 per 100,000. The most frequent histological subtypes were gastrointestinal stromal tumor (18%; 1.1/100,000), unclassified sarcoma (16%; 1/100,000), liposarcoma (15%; 0.9/100,000) and leiomyosarcoma (11%; 0.7/100,000). Conclusions/Significance The observed incidence of sarcomas was higher than expected. This study is the first detailed investigation of the crude incidence of histological and molecular subtypes of sarcomas.

Abstract
BACKGROUND Rhabdomyosarcoma is the most common soft tissue sarcoma of childhood. Prognosis for patients with metastatic disease has not improved significantly in the past decades. High-dose chemotherapy (HDC) seems to be an attractive option to treat minimal residual disease in metastatic rhabdomyosarcoma patients. OBJECTIVES The objective of the review was to assess the effectiveness of HDC with stem cell rescue (SRC) versus standard-dose chemotherapy in improving event-free survival (EFS) and overall survival (OS) of children and young adults with metastatic rhabdomyosarcoma. SEARCH STRATEGY We searched the databases of MEDLINE (1966 to December 2009), EMBASE (1980 to December 2009) and CENTRAL (The Cochrane Library Issue 1, 2009). In addition, we handsearched the reference lists of selected papers and conference proceedings of the SIOP, ASPHO and ASCO meetings (all 2000 to 2009). SELECTION CRITERIA Randomised controlled trials (RCT), prospective or historical controlled clinical trials (CCT), in which HDC with SCR was compared to conventional chemotherapy and prospective case series (non-controlled clinical trials) including at least 20 naive metastatic rhabdomyosarcoma patients DATA COLLECTION AND ANALYSIS Two review authors independently performed the study selection, quality assessment and data extraction. MAIN RESULTS No RCTs could be identified. We identified one prospective CCT, one retrospective CCT and one non-controlled clinical trial. Another CCT has been published as an abstract. All studies have severe methodological limitations, in particular selection bias could not be excluded. One CCT reported a significantly worse OS compared to oral maintenance therapy, however in a subgroup of high-risk patients no difference could be found. The retrospective CCT reported a similar survival for HDC compared to conventional chemotherapy. The non-controlled clinical trial and the CCT reported as a conference proceeding reported survival outcomes comparable to previous studies. Data on toxicity showed more grade 3-4 toxicity in the HDC group. However, there was no difference in the number of toxic deaths. AUTHORS' CONCLUSIONS Overall, the results of this review do not justify the use of HDC with SCR as a standard therapy for children with metastatic rhabdomyosarcoma. However, all reported studies were possibly subject to significant bias, especially selection bias. This might have underestimated the measured effect of HDC. As a result, a clinically important excess of adverse risk patients in the HDC arms may explain the non-beneficial effect of HDC. Only a large prospective RCT will be able to answer the question of whether HDC with SCR adds to survival or not definitively.

Abstract
Chest wall tumors in childhood are major challenges with respect to diagnostic workup and treatment. Incidence rate is less than 1 per 1,000,000 and various benign and malignant diseases are noted. From the malignant diseases, Ewing tumors and rhabdomyosarcoma tumors are most often seen. Depending on diagnosis, staging, and age, therapy has to be tailored for each patient, which should be discussed in a multidisciplinary team setting. Radical resection is in most cases the major component of treatment. Use of chemotherapy depends on the diagnosis. In soft-tissue tumors, previously considered to be chemotherapy insensitive, favorable results are currently reported. The role of radiotherapy is debated owing to its pronounced late sequelae in children, but should be added when adequate margins cannot be achieved by surgery.

Abstract
This population-based study is based on 5802 cases of soft tissue sarcomas (STS) in children aged 0-14 years extracted from the database of the Automated Childhood Cancer Information System (ACCIS) and registered in population-based cancer registries in Europe for the period 1978-1997. STS represent almost 8% of neoplasms in children, almost half of whom are less than 5 years at diagnosis. Rhabdomyosarcoma is the most frequent childhood STS (50%). During 1988-1997 the age-standardised incidence of STS in Europe was 9.1 per million children, lowest in the West and East and highest in the North. The incidence of STS increased almost 2% per year over the period 1978-1997, attributable mostly to increase in genito-urinary rhabdomyosarcoma. Prognosis of children with STS was related to age and site of tumour. Five-year survival of children with STS increased from 46% in 1978-1977 to 66% in 1993-1997, reaching 74% in the North for those diagnosed in 1993-1997. This improvement is ascribed to therapy advances.

Abstract
Pediatric undifferentiated soft tissue sarcomas represent a major challenge for pathologists and clinicians. The goal of this study was to identify cases that warranted this diagnosis by current standards of analysis and then determine if there are clinicopathological commonalities that may be useful for diagnosis, management, and prognosis. Eighteen potential patients were identified using the institutional pathology database. Three cases were reclassified as specific sarcomas, and 2 cases had insufficient material for molecular analysis, leaving 13 cases for pathological review and 12 patients for radiological and clinical review. There were 7 males and 6 females. The median age at diagnosis was 11 years (1 month to 16 years). Tumors commonly involved the trunk (7 of 13; 54%) and ranged in size from 1.7 to 14.5 cm (mean, 6.7 cm). Eleven patients received ifosfamide/etoposide chemotherapy and 4 received irradiation. Five-year event-free and overall survival (EFS and OS) rates were 54% and 74%, respectively. The predominant histological pattern was round to plump spindled cells forming sheets (9 of 13; 69%) and severe atypia was associated with decreased survival (P = 0.048). Immunohistochemistry showed positivity for vimentin (92%), CD117 (92%), and vascular endothelial growth factor (69%), and 8% to 23% showed focal positivity for epithelial, neural, or myogenic markers. Tumors were uniformly negative for translocations associated with pediatric sarcomas. The presence of certain common morphological and immunohistochemical features in the absence of specific molecular genetic abnormalities allows for a diagnosis of pediatric undifferentiated soft tissue sarcoma; however, whether this group of neoplasms forms a unique category of tumors or a common precursor pathway for a number of different sarcomas awaits further study.

Abstract
Lumps and bumps of the scalp are a common presenting complaint in children and often pose a diagnostic dilemma. These lesions can be difficult to image, with evaluation confounded by their small size. However, accuracy in diagnosis is critical because the diagnostic and therapeutic implications can vary significantly. The clinical examination can be helpful in developing the differential diagnosis and the imaging strategy. Often, however, a single imaging study is insufficient, and the radiologist finds it necessary to image with more than one modality to correctly diagnose a lesion and provide adequate information for the surgeon. Radiography and ultrasonography are often the initial screening diagnostic tests, followed by magnetic resonance (MR) imaging or computed tomography (CT) for more detail. Multidetector thin-section CT and thin-section MR imaging with surface coils are beneficial in the work-up of these small lesions of the head and neck. The use of newer MR imaging sequences such as heavily T2-weighted single-shot turbo spin-echo imaging and diffusion-weighted imaging can improve the characterization of difficult lesions. Familiarity with the variety of new imaging tools and techniques that are available can help characterize pediatric head and neck lesions and guide clinical management.

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
OBJECTIVE To understand the clinical presentation, management, and natural history of paranasal rhabdomyosarcoma. DESIGN Retrospective case series review. METHODS Retrospective medical record review of patients less than 20 years of age who presented to our facility with rhabdomyosarcoma of the nasal cavity or paranasal sinuses. RESULTS Medical records of all pediatric patients seen in our pediatric otolaryngology clinic were reviewed from January 1, 1995, through December 31, 2000. Three patients were identified with sinonasal rhabdomyosarcoma. Their presentation, evaluation, and treatment were evaluated. Relevant literature 1966 to the present was reviewed with the assistance of Medline. CONCLUSIONS Rhabdomyosarcoma is an aggressive pediatric malignancy, requiring a high index of suspicion to detect it in its earliest stages. Patients with suggestive symptoms should undergo a full evaluation including nasal endoscopy and imaging. Because the current chemotherapy protocols are more effective on localized disease, early diagnosis is crucial to patient survival.

Abstract
We retrospectively analyzed the MRI findings of rhabdomyosarcoma (RMSA) in 23 patients to evaluate its role in staging and management. Heterogeneous signal abnormalities were noted in the sarcoma lesions with significant contrast enhancement. Seven head and neck cases showed direct bone invasion and destruction; only one had distant bony metastasis. Metastasis was noted in the lymph nodes, lung, bone, abdominoperitoneum, and head and neck soft tissue. MRI findings of RMSA are most helpful in staging and assessing therapeutic response.

Abstract
Costello syndrome is a well delineated mental retardation syndrome of unknown aetiology in which the occurrence of benign tumours, especially papillomata, is recognised. We report two children in whom the diagnosis of Costello syndrome was made in the first months of life, who both developed a retroperitoneal embryonal rhabdomyosarcoma. Although not previously reported, the occurrence of this relatively uncommon childhood tumour in two girls with Costello syndrome suggests that an increased risk of malignancy may be part of this condition. The genetic basis of this susceptibility requires further clarification.

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
Cancer is an infrequent disease in childhood. However, it is responsible for 13.06% of child deaths between 1 and 14 years in Cuba. The aim of our work was to describe the incidence of childhood cancer in the period 1986 to 1990 using data reported to the National Cancer Registry (NCR) of Cuba. All cancer cases between 0 and 14 years of age reported to the NCR in the period 1986 to 1990, were included. The cases were classified histologically, by age and gender. Average age-specific and age-standardized rates were calculated; 1428 children were registered, an average of 286 each year, with a mean annual rate of 117.8 per million. The world-population standardized rate was 120.7 and the male-to-female ratio was 0.98. Leukaemias, lymphomas and malignant tumours of the central nervous system were the most common childhood neoplasm groups. The majority of leukaemias were acute lymphoblastic leukaemias (ALL), and the incidence peak extended until 6 years of age. The first peak of incidence of Hodgkin's disease is found in older age-groups. Burkitt's lymphoma showed a male-to-female ratio of 0.44. Most of the hepatic tumours were carcinomas, and only one fourth were hepatoblastomas. In bone tumours, similar rates were observed for osteosarcomas and Ewing's sarcoma.

Abstract
Incidence rates of cancers of childhood in Thailand are presented for the first time, and compared with results from cancer registries in Asia, Europe and the USA. As elsewhere in the world, leukaemia (principally acute lymphocytic), brain tumours and lymphomas comprise two-thirds of all childhood neoplasms. Carcinomas are rare, but the principal sites (liver, nasopharynx, thyroid and salivary gland) are extremely unusual elsewhere. Several features of the cancer pattern correspond to that in other Asian populations (China, Japan, Philippines), in particular the low incidence of Hodgkin's disease, Wilms' tumour and Ewing's sarcoma. Conversely, Burkitt's lymphoma is more common than elsewhere, although this may represent increasing awareness of this diagnosis amongst clinicians in recent years.

Abstract
BACKGROUND Malignant neoplasms of the structural tissues, consisting mostly of soft tissue sarcomas, are morphologically diverse and rarely treated for epidemiologic purposes as individual entities. Our understanding to date of the pattern of occurrence of sarcomas is based largely on reports of limited individual clinic experience or case-control studies, each driven by a single hypothesis, and there have been virtually no descriptions according to specific morphologic type. METHODS The accumulated coverage of the SEER populations offers an opportunity to correct this deficit. Each of the diagnoses has been reported and coded using a single set of rules and described in relation to the population at risk in terms of age, sex, race, calendar period, anatomic location, and outcome. In addition, each morphologic type has been compared with each of the others with respect to the pattern of occurrence and survival. RESULTS For most of the individual morphologic entities, the pattern of occurrence is specific and unlike other patterns. Differences according to anatomic site, age, sex, race, and period-specific survival were found. Partly because of changes in diagnostic criteria over the years, differences in secular trend, other than that for Kaposi's sarcoma, could not be verified. Although some types of sarcoma may have important genetic determinants, there is evidence of environmental causation in others; for some varieties both genetic and environmental factors may operate. There is no evidence of improvements in survival. CONCLUSIONS The most likely basis for the observed patterns are morphology-specific differences in etiology and growth phase. Each of the entities should be considered etiologically distinct and should be studied individually whenever possible.
