Abstract
BACKGROUND This study aimed to assess the impact that the quality of primary and subsequent surgeries has on the survival of patients with para-testicular rhabdomyosarcoma (PTRMS). METHODS Patients with localized (IRS I-III) and metastatic (IRS IV) PTRMS were enrolled in the two Cooperative Weichteilsarkom Studiengruppe (CWS) trials (CWS-96, CWS-2002P) and the Soft Tissue Sarcoma Registry (SoTiSaR). RESULTS Among 196 patients (median age, 8.4 years), 106 (54.1%) had primary complete resection. Image-defined lymph node (LN) disease was detected in 21 (11.5%) patients in the localized cohort and 12 (92.3%) patients in the metastatic cohort. The 5-year event-free survival (EFS) and overall survival (OS) were respectively 87.3% and 94.0% for the patients with localized PTRMS and 46.2% and 42.2% for the patients with metastatic PTRMS. Protocol violations during the primary surgery (PV-PS) were observed in 70 (42%) of the IRS I-III patients. This resulted in higher rates of R1/R2 resections (n = 53 [76%] vs n = 20 [21%]; p < 0.001) with a need for pretreatment re-excision (PRE) (n = 50 [83%] vs n = 10 [17%]; p < 0.001) compared with the patients undergoing correct primary surgery. Protocol violations during PRE occurred for 13 (20%) patients. Although PV-PS did not influence the 5-year EFS or OS in the localized PTRMS cohort, the unadjusted log-rank test showed that R status after PRE is a prognostic factor for 5-year OS (R1 vs R0 [81.8% vs 97.6%]; p = 0.02). CONCLUSIONS The quality of surgical local control in PTRMS is unsatisfactory. Emphasis should be placed on evaluating the resection status after PRE in further clinical trials.

Abstract
BACKGROUND Extremity rhabdomyosarcoma differs from other soft tissue sarcomas, being highly sensitive to chemotherapy and radiotherapy and having a high rate of metastasis to lymph nodes. Therefore, the treatment modality differs from that of other soft tissue sarcomas. The purpose of this study was to conduct a longitudinal questionnaire survey of orthopedic oncologists in charge of surgical treatment for extremity rhabdomyosarcoma in Japan to determine whether the treatment modality chosen here is in line with the international and national treatment ones. METHODS Questionnaire surveys were conducted in 2012 and 2019 to orthopedic oncologists of Japanese Orthopaedic Association and Japanese Musculoskeletal Oncology Group. RESULTS Responses were obtained from 80 facilities and 76 facilities, respectively. Fewer than 50% of the facilities treated one or more patients a year in both years. Many facilities first performed diagnostic biopsy, but most did not perform pretreatment re-excision. The number of facilities that provided radiotherapy in addition to surgery increased significantly from 2012 to 2019 (P = 0.028), but it was still 21% in 2019. The number of facilities performing excision and lymph node dissection was 19% in both 2012 and 2019, which was a very low result without improvement. The departments responsible for follow-up have been changed to pediatrics and orthopedic oncology in tandem (P = 0.0004). CONCLUSIONS Radiotherapy and pathological evaluation of lymph nodes are important for improving the prognosis of patients with extremity rhabdomyosarcoma. It is necessary to continue and develop more efficient educational activities on the appropriate medical treatment modalities for extremity RMS.

Abstract
In Soft Tissue Sarcomas (STS) referral centre many patients have already had an incomplete tumour resection. In the majority of specimen, tumoral residual is detected and linked to a worsen prognosis. Systematic surgical re-resection of the scar tissue area is often performed. Some authors suggested to postpone re-resections until a clinically evident local recurrence is detected. A searching strategy was applied to Pubmed-Central and Ovid Medline. Odds ratio (OR) for local recurrence (LR), distant metastasis (MTS) or overall survival (OS) were calculated comparing patients who had tumour residual to people who hadn't. OR of local recurrences, distant metastasis and OS were calculated in planned vs unplanned-excisions groups. OR to develop a metastasis and OS after a local recurrences were calculated. Residual tumour led to an OR for LR of 3,56, OR of MTS was 3,42; OR of decreased OS was 3,42. Having a LR lead to a OR of 1,55 for MTS and to a OR of decreased OS of 2,32. Patients who underwent a re-excision compared to planned surgery did not have an increased OR of LR and had an OR to develop a MTS of 0,56. Our data confirm that there is a strong correlation between local recurrences, distant relapses and overall survival. Although there is a selection bias; this analysis highlights the optimal oncological outcome in patients who underwent re-resection. The rationale for systematic re-resection after unplanned excision of soft tissue sarcomas is very strong and this treatment remains the gold standard of care in these patients.

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.

Surgery alone is sufficient therapy for children and adolescents with low-risk synovial sarcoma: A joint analysis from the European paediatric soft tissue sarcoma Study Group and the Children's Oncology Group. Eur J Cancer 2017; 78:1-6. [PMID: 28391003 DOI: 10.1016/j.ejca.2017.03.003] [Citation(s) in RCA: 49] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2016] [Revised: 01/07/2017] [Accepted: 03/09/2017] [Indexed: 12/31/2022]
Abstract
BACKGROUND Multimodal risk-adapted treatment is used in paediatric protocols for synovial sarcoma (SS). Retrospective analyses suggest that low-risk SS patients can be safely treated with surgery alone, but no prospective studies have confirmed the safety of this approach. This analysis pooled data from the two prospective clinical trials to assess outcomes in SS patients treated with a surgery-only approach and to identify predictors of treatment failure. METHODS Patients with localised SS enrolled on the European paediatric Soft tissue sarcoma Study Group (EpSSG) NRSTS2005 and on the Children Oncology Group (COG) ARST0332 trials, treated with surgery alone were eligible for this analysis. Patients must have undergone initial complete resection with histologically free margins, with a grade 2 tumour of any size or a grade 3 tumour ≤5 cm. RESULTS Sixty patients under 21 years of age were eligible for the analysis; 36 enrolled in the COG (from 2007 to 2012) and 24 in the EpSSG study (from 2005 to 2012). The 3-year event-free survival was 90% (median follow-up 5.2 years, range 1.9-9.1). All eight events were local tumour recurrence, whereas no metastatic recurrences were seen. All patients with recurrence were effectively salvaged, resulting in 100% overall survival. CONCLUSION This joint prospective analysis showed that patients with adequately resected ≤5 cm SS, regardless of grade, can be safely treated with a surgery-only approach. Avoiding the use of adjuvant chemotherapy and radiotherapy in this low-risk patient population may decrease both short- and long-term morbidity and mortality.

Abstract
Pediatric non-rhabdomyosarcoma soft tissue sarcomas (NRSTS) are a heterogeneous group encompassing more than 50 different histological diagnoses arising from primitive mesenchymal tissue. Together, they comprise about half the soft tissue sarcomas diagnosed in children and young adults. Despite each histologies relative rarity, their management schema is similar among the different NRSTS histologies. Surgical management is an important component of the multimodal treatment strategy of all these tumors. Resection with negative margins, while maintaining function, plays an important role as a primary treatment of these patients as well as diminishing the risks of local and distant recurrence.

Abstract
Nonrhabdmyosarcoma soft tissue sarcomas (NRSTS) include a cluster of different types of soft tissue sarcomas clubbed together due to the rarity of individual subtypes. The diagnostic accuracy is lately reinforced due to the availability of immunohistochemical and molecular markers. Surgery is the central modality of treatment since many of them are insensitive to chemotherapy. With the availability of rational risk stratification system, efforts are in progress to evaluate the role of neoadjuvant chemotherapy and radiotherapy to improve outcomes especially for the locally advanced disease. The survival remains dismal for metastatic disease. This review highlights the current status of NRSTS and also describes the experience from a single centre in treatment of NRSTS.

Abstract
Pediatric soft tissue sarcomas are a group of malignant neoplasms arising within embryonic mesenchymal tissues during the process of differentiation into muscle, fascia and fat. The tumors have a biphasic peak for age of incidence. Rhabdomyosarcoma (RMS) is diagnosed more frequently in younger children, whereas adult-type non-RMS soft tissue sarcoma is predominately observed in adolescents. The latter group comprises a variety of rare tumors for which diagnosis can be difficult and typically requires special studies, including immunohistochemistry and molecular genetic analysis. Current management for the majority of pediatric sarcomas is based on the data from large multi-institutional trials, which has led to great improvements in outcomes over recent decades. Although surgery remains the mainstay of treatment, the curative aim cannot be achieved without adjuvant treatment. Pre-treatment staging and risk classification are of prime importance in selecting an effective treatment protocol. Tumor resectability, the response to induction chemotherapy, and radiation generally determine the risk-group, and these factors are functions of tumor site, size and biology. Surgery provides the best choice of local control of small resectable tumors in a favorable site. Radiation therapy is added when surgery leaves residual disease or there is evidence of regional spread. Chemotherapy aims to reduce the risk of relapse and improve overall survival. In addition, upfront chemotherapy reduces the aggressiveness of the required surgery and helps preserve organ function in a number of cases. Long-term survival in low-risk sarcomas is feasible, and the intensity of treatment can be reduced. In high-risk sarcoma, current research is allowing more effective disease control.

Abstract
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. While surgery remains the mainstay of treatment, the role of adjuvant therapy is not yet clear and our understanding of the biology and natural history of nonrhabdomyosarcoma soft tissue sarcomas is still incomplete. This review presents the latest data on nonrhabdomyosarcoma soft tissue sarcoma treatment and outcome, and the rationale behind a risk-adapted treatment program that investigates the role of full-dose ifosfamide-doxorubicin chemotherapy in improving the response rate of patients with unresectable disease, the chances of avoiding adjuvant chemotherapy in low-risk synovial sarcomas, and the possible role of chemotherapy in high-risk adult-type soft tissue sarcomas.

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
OBJECTIVE To determine the efficacy of primary re-excision alone for treatment of soft tissue sarcomas after recent incomplete resection, the frequency and clinical importance of detecting residual tumor in resected scars, and prognostic factors associated with the procedure. DESIGN Retrospective case series. ANIMALS 41 dogs. PROCEDURES Medical records of dogs that had undergone recent incomplete excision of a soft tissue sarcoma at a referring veterinary practice and subsequent re-excision of the scar at the Colorado State University Veterinary Medical Center were reviewed. Owners and referring veterinarians were contacted for follow-up information. Slides from re-excised specimens were reviewed. Dogs that underwent radiation therapy after the re-excision procedure were excluded. RESULTS 41 dogs met the inclusion criteria, and long-term follow-up information was available for 39 dogs. Median follow-up time was 816 days. Local recurrence of tumor developed in 6 of 39 (15%) dogs, and distant metastasis occurred in 4 of 39 (10%) dogs. Healthy tissue margins of 0.5 to 3.5 cm were achieved at re-excision. Residual tumor was identified in 9 of 41 (22%) resected scars. No tumor-, patient-, or treatment-related variables were associated with local recurrence except for the presence of liposarcoma or fibrosarcoma or whether fine-needle aspiration had been performed prior to surgery. CONCLUSIONS AND CLINICAL RELEVANCE After incomplete resection of soft tissue sarcomas, resection of local tissue should be performed, even if excisable tissue margins appear narrow. A long-term favorable prognosis is achievable without radiation therapy or amputation. The presence of residual tumor in resected scar tissue should not be used to predict local recurrence.

Abstract
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. Local therapy is essential, in which surgery remains an important adjunct. However, it has to be applied in a multidisciplinary, combined fashion in close cooperation with oncologists, pathologists and radiotherapeutists. Current 5-year survival in rhabdomyosarcoma reaches 60-70% in nonmetastatic cases and remains below 20% in metastatic situations. Outcome in pediatric nonrhabdomyosarcoma STS is similar.

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.
