INTRODUCTION: Many authors suggest that extremity soft tissue sarcomas (ESTS) do not change significantly in size during preoperative radiotherapy (RT). This conebeam CT study investigates the justification to deliver the entire course with one initial RT plan by observing anatomical changes during RT. METHODS: In 2015-2017, 99 ESTS patients were treated with either curative (n=80) or palliative intent (n=19) with a regimen of at least 6 fractions. CTV-to-PTV margin was 1cm...

BACKGROUND: Mesenchymal malignancies are relatively rare tumors with distinct behaviors that are usually surgically removal. However, it is sometimes impossible to perform such surgery according to standardized procedures. In particular, surgical removal of intraperitoneal and retroperitoneal tumors differs among individuals. CASE REPORTS: We present two cases with intra-abdominal and retroperitoneal sarcomas who were treated at our comprehensive oncology center...

Background: Preoperative radiotherapy is often used to facilitate excision of soft-tissue sarcomas. We aimed define factors that affect local tumour control and patient survival. Methods: A single institution registry study of 89 patients with non-metastatic soft-tissue sarcomas having preoperative radiotherapy between 1994 and 2014. Radiologic (presence of peritumoural oedema and volume change following radiotherapy) and histopathologic (tumour volume, grade and surgical margin) parameters were recorded...

PURPOSE: Localized adult high-grade soft tissue sarcomas (STS) usually require multimodality treatment including surgery, radiotherapy, chemotherapy and hyperthermia. If maximal preoperative tumor-shrinkage is envisaged, neoadjuvant chemotherapy + radiation (CRT) is often applied, however at the expense of relatively high toxicities and increased postoperative complication rates. This study aims to compare preoperative CRT with neoadjuvant chemotherapy + regional hyperthermia (HCT) regarding histopathological response, toxicity and outcome...

BACKGROUND/OBJECTIVES: For pediatric patients with large, high-grade extremity non-rhabdomyosarcoma soft tissue sarcomas (NRSTS), 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 to rates following postoperative chemoradiation. We assessed the impact of preoperative RT technique on target coverage in relationship to dose to skin and adjacent joints to determine if acute wound complications and late musculoskeletal injury might be influenced by treatment technique...

OBJECTIVES: Synovial sarcoma, a distinct subtype of soft tissue sarcomas (STS), is typically found in young patients. Long history of symptoms and heterogeneous clinical presentation sometimes delays diagnosis. Children have been reported to have a better prognosis than adults in some series. The main emphasis of this study was to determine differences between children and adults and to investigate prognostic factors regarding cancer specific survival (CSS). METHODS: 248 patients treated between 1982 and 2014 at one department were included...

Small randomized trials have not shown an overall survival (OS) difference among local treatment modalities for patients with extremity soft-tissue sarcomas (E-STS) but were underpowered for OS. We examine the impact of local treatment modalities on OS and sarcoma mortality (SM) using two national registries. The National Cancer Database (NCDB) and the Surveillance, Epidemiology, and End Results (SEER) Program were analyzed separately to identify patients with stage II-III, high-grade E-STS diagnosed between 2004 and 2013 and treated with (1) amputation alone, (2) limb-sparing surgery (LSS) alone, (3) preoperative radiation therapy (RT) and LSS, or (4) LSS and postoperative RT...

REVIEW
Angelo Paolo Dei Tos, Sylvie Bonvalot, Rick Haas
Soft tissue sarcomas are a heterogeneous group of rare malignancies. The diagnostic gold standard is conventional histomorphology with integrated immunohistochemistry. Molecular genetic profiling has identified new subgroups of undifferentiated sarcomas involving genetic rearrangements with creation of fusion genes. Accurate classification of sarcomas is critical for appropriate clinical decision-making which should involve a multidisciplinary team. A preoperative biopsy is necessary to confirm a diagnosis...

PURPOSE: Radio-hyperthermo-chemo (RHC) therapy, which combines radiotherapy, hyperthermia, and chemotherapy, for malignant soft tissue tumors has been introduced with the aim of decreasing the possibility of local recurrence after surgery. To avoid unnecessary neoadjuvant therapy and to plan the appropriate surgical treatment, surveillance of RHC therapeutic efficacy during treatment is necessary. In this study, we determined the optimal response criteria to evaluate the efficacy of RHC by comparing preoperative images before and after RHC with pathological evaluation of necrosis in the resected tumor...
