Preoperative Intensity Modulated Radiation Therapy Compared to Three-Dimensional Conformal Radiation Therapy for High-Grade Extremity Sarcomas in Children: Analysis of the Children's Oncology Group Study ARST0332.

Int J Radiat Oncol Biol Phys 2019 Jan 10;103(1):38-44. Epub 2018 Sep 10.

Department of Radiation Oncology and Molecular Radiation Sciences, Johns Hopkins University School of Medicine, Baltimore, Maryland. Electronic address:

Purpose: For pediatric patients with large, high-grade, extremity nonrhabdomyosarcoma soft-tissue sarcomas, preoperative radiation therapy (RT) provides the opportunity for smaller radiation fields and tumor shrinkage resulting in less extensive surgery. The potential disadvantage is an increased risk of wound complications after surgery compared with rates after postoperative chemoradiation. We assessed the impact of preoperative RT technique on target coverage in relationship to dose to skin and adjacent joints to determine whether acute wound complications and late musculoskeletal injury might be influenced by treatment technique.

Alveolar soft part sarcoma in children and adolescents: The European Paediatric Soft Tissue Sarcoma study group prospective trial (EpSSG NRSTS 2005).

Pediatr Blood Cancer 2018 Apr 29;65(4). Epub 2017 Dec 29.

Fondazione IRCCS Istituto Nazionale Tumori Milano, Milan, Italy.

Background: As alveolar soft part sarcomas (ASPS) are rare with no prospective series within pediatric sarcoma trials, the European Paediatric Soft Tissue Sarcoma Study Group (EpSSG) examined the clinical data and outcomes of ASPS enrolled in a multinational study of nonrhabdomyosarcoma soft tissue sarcomas (NRSTS).

Patients And Methods: Twenty-two patients with ASPS were enrolled into the EpSSG NRSTS 2005 study. After surgical resection, subsequent treatment depended on the stratification of patients for completeness of resection and Intergroup Rhabdomyosarcoma Study (IRS) stage, size, and French Federation of Cancer Centres Sarcoma Group (FNCLCC) grade.

Salvage rates and prognostic factors after relapse in children and adolescents with malignant peripheral nerve sheath tumors.

Pediatr Blood Cancer 2018 Feb 19;65(2). Epub 2017 Sep 19.

Pediatric Oncology Unit, Fondazione IRCCS Istituto Nazionale Tumori, Milano, Italy.

Background: Malignant peripheral nerve sheath tumor (MPNST) is one of the most common nonrhabdomyosarcoma soft tissue sarcomas encountered in pediatric age, and it is generally characterized by poor outcome, particularly for relapsing patients.

Materials And Methods: This study considered 73 patients <21 years of age with relapsing MPNST observed among 120 patients enrolled in Italian pediatric protocols from 1979 to 2004. With the aim of possibly establishing a risk-adapted stratification, patients' outcome was examined using univariate and multivariate analysis based on clinical features at onset, first-line treatments, clinical findings at the time of first relapse, and second-line treatments.

Nonrhabdomyosarcoma soft tissue sarcoma (NRSTS) in pediatric and young adult patients: Results from a prospective study using limited-margin radiotherapy.

Cancer 2017 Nov 31;123(22):4419-4429. Epub 2017 Jul 31.

Department of Radiation Oncology, St. Jude Children's Research Hospital, Memphis, Tennessee.

Background: Indications for and delivery of adjuvant therapies for pediatric nonrhabdomyosarcoma soft tissue sarcoma (NRSTS) have been derived largely from adult studies; therefore, significant concern remains regarding radiation exposure to normal tissue. The authors report long-term treatment outcomes and toxicities for pediatric and young adult patients with high-grade NRSTS who were treated on a prospective trial using limited-margin radiotherapy.

Methods: Sixty-two patients (ages 3-22 years) with predominantly high-grade NRSTS requiring radiation were treated on a phase 2 institutional study of conformal external-beam radiotherapy and/or brachytherapy using a 1. Read More

The Role of F-FDG-PET/CT in Pediatric Sarcoma.

Semin Nucl Med 2017 05 18;47(3):229-241. Epub 2017 Jan 18.

Diagnostic Imaging Department, Saint Jude Children's Research Hospital, Memphis, TN.

Considerable debate remains regarding how best to incorporate F-FDG-PET/CT into clinical practice for pediatric sarcomas. Although there is a clear role for F-FDG-PET/CT in staging pediatric sarcoma, the value of F-FDG-PET/CT in prognostication for pediatric sarcomas remains unclear. In osteosarcoma, Ewing sarcoma, and rhabdomyosarcoma, F-FDG-PET/CT may be most useful in the identification of skeletal metastases, where the literature consistently suggests that it has improved sensitivity and specificity as compared to bone scintigraphy.

Proton Therapy in Children: A Systematic Review of Clinical Effectiveness in 15 Pediatric Cancers.

Int J Radiat Oncol Biol Phys 2016 May 17;95(1):267-78. Epub 2015 Oct 17.

Department of Radiation Oncology, University of Leuven, Leuven, Belgium.

Because it spares many normal tissues and reduces the integral dose, proton therapy (PT) is the preferred tumor irradiation technique for treating childhood cancer. However, to the best of our knowledge, no systematic review of the clinical effectiveness of PT in children has been reported in the scientific literature. A systematic search for clinical outcome studies on PT published between 2007 and 2015 was performed in Medline (through OVID), EMBASE, and the Cochrane Library. Read More

Grading of nonrhabdomyosarcoma soft tissue sarcoma in children and adolescents: a comparison of parameters used for the Fédération Nationale des Centers de Lutte Contre le Cancer and Pediatric Oncology Group Systems.

Cancer 2010 May;116(9):2266-74

Department of Pathology, St. Jude Children's Research Hospital, Memphis, Tennessee, USA.

Background: Two systems for grading soft tissue sarcoma are widely used currently: the National Cancer Institute (NCI) and the Fédération Nationale des Centers de Lutte Contre le Cancer (FNCLCC) systems. Both were developed using cohorts of predominantly adult patients. The Pediatric Oncology Group (POG) system, based on the NCI system, was adapted for grading pediatric nonrhabdomyosarcoma soft tissue sarcoma (NRSTS). Read More

The symptom interval in children and adolescents with soft tissue sarcomas.

Cancer 2010 Jan;116(1):177-83

Pediatric Oncology Unit, National Tumor Institute, Milan, Italy.

Background: In a series of 575 patients < or =21 years of age with soft tissue sarcomas (STSs), the authors investigated the association patterns between symptom interval (ie, the period between the onset of the first symptoms or signs of the disease and its definitive diagnosis) and patient/tumor characteristics or disease outcome (in terms of survival).

Methods: The analysis was based on multivariate models (linear for associations with patient/tumor characteristics and Cox's for survival).

Results: The symptom interval ranged between 1 week and 60 months (median, 2 months) and tended to be longer the older the patient (ie, the interval was longer in adolescents than in children) and the larger the tumor's size, and for tumors located at the extremities and for nonrhabdomyosarcoma STSs (as opposed to rhabdomyosarcomas).

Pediatric nonrhabdomyosarcoma soft tissue sarcomas.

Oncologist 2008 Jun;13(6):668-78

Department of Oncology, St. Jude Children's Research Hospital, Department of Oncology, 332 N. Lauderdale Street, ALSAC-6032, Memphis, TN 38105-2794, USA.

The nonrhabdomyosarcoma soft tissue sarcomas (NRSTSs) are a heterogeneous group of mesenchymal cell neoplasms that account for about 4% of childhood cancers. Because each histologic subtype of NRSTS is rare, they have been poorly studied and little is known about their biology, natural history, or optimal treatment. Data from adults with soft tissue sarcomas provide some helpful insight, but adult and childhood NRSTSs differ considerably in the distribution of their histologic subtypes, and certain entities are known to behave differently in young children.

Role of chemotherapy in pediatric nonrhabdomyosarcoma soft-tissue sarcomas.

Authors:
Andrea Ferrari

Expert Rev Anticancer Ther 2008 Jun;8(6):929-38

Pediatric Oncology Unit, Fondazione IRCCS Istituto Nazionale Tumori, Via G Venezian, 1 20133 Milano MI, Italy.

The definition of nonrhabdomyosarcoma soft-tissue sarcomas includes a varied group of malignant soft part tumors that can occur in childhood, but the majority are entities typically observed in adult age. Similar to their adult counterparts, pediatric nonrhabdomyosarcoma soft-tissue sarcomas are usually considered scarcely sensitive to chemotherapy, but treatment strategies for these tumors have changed to some degree in recent years, and multiple-modality treatments that also include chemotherapy have increasingly been attempted. Subsets of patients with specific histological subtypes and prognostic variables have been thought likely to benefit from chemotherapy. Read More

Future Oncol 2006 Oct;2(5):667-73

Medical University of Gdansk, Department of Surgery & Urology for Children & Adolescents, Ul. Nowe Ogrody 1-6, 80-803 Gdansk, Poland.

Pediatric soft tissue sarcomas (STSs), of which rhabdomyosarcoma is the most common, constitute approximately 5-6% of all cancers in children. Biopsy, being incisional or rarely excisional, is an essential primary diagnostic step, while in some cases it may be followed by primary re-excision to establish a correct diagnosis in which molecular analysis can be helpful. Most European STS treatment groups favor preoperative chemotherapy, sometimes combined with preoperative irradiation. Read More

New concepts for the treatment of pediatric nonrhabdomyosarcoma soft tissue sarcomas.

Expert Rev Anticancer Ther 2005 Apr;5(2):307-18

Istituto Nazionale Tumori, Via G.Venezian, 1-20133 Milan, Italy.

Nonrhabdomyosarcoma soft tissue sarcomas form a group of rare tumors with a different biology and clinical behavior. The recently established European Pediatric Soft Tissue Sarcoma Study Group is organizing a new study devoted specifically to these tumors that were formerly treated according to the principles derived from experience with rhabdomyosarcoma, which is a clearly distinct entity. The new study includes two prospective trials, one for synovial sarcoma and the other for adult-type nonrhabdomyosarcoma soft tissue sarcomas. Read More

PET/CT in the evaluation of childhood sarcomas.

AJR Am J Roentgenol 2005 Apr;184(4):1293-304

Department of Radiological Sciences, St. Jude Children's Research Hospital, 332 N Lauderdale St., Memphis, TN 38105, USA.

Objective: Our objective was to review our preliminary experience with PET/CT in evaluating childhood sarcomas including rhabdomyosarcoma (n = 28), the Ewing's sarcoma family of tumors (n = 14), nonrhabdomyosarcoma soft-tissue sarcoma (n = 9), osteosarcoma (n = 8), chondrosarcoma (n = 1), and embryonal sarcoma (n = 1).

Conclusion: We found PET/CT useful in depicting an unknown primary rhabdomyosarcoma and detecting unsuspected and unusual metastatic sites of childhood sarcomas. It was useful in monitoring response to chemotherapy, radiation therapy, and radiofrequency ablation and aided the postoperative evaluation of tumor resection sites. Read More

Nonrhabdomyosarcoma soft tissue sarcomas account for approximately 40% of all soft tissue sarcomas in children. Although these tumors are typically grouped together, individual tumor types with different biological characteristics have been found that may impact on the optimal therapy for each type of sarcoma in the future. Most of the current information regarding this tumor comes from the adult literature. Read More
