Abstract
With nearly 15,000 new cases of soft-tissue sarcoma (STS) in the United States each year, early diagnosis and therapeutic management is imperative for successful patient outcomes. Primary STS is conventionally treated with a combination of wide-margin resection, neoadjuvant or adjuvant radiation therapy, and, in specific cases, adjuvant chemotherapy. However, in situations of complex disease presentation, guidelines for treatment are less clearly outlined. Limited metastatic disease, local recurrence, fungating STSs, and unplanned or incomplete resections of STSs present unique challenges for the multidisciplinary care team. The management of complex STS clinical scenarios usually involves limb-salvage resection or amputation as well as some combination of radiation therapy and/or ablative interventional radiology techniques. As a result, a multidisciplinary team approach is essential for treating patients in these challenging scenarios, with a recent focus on the integration of plastic and reconstructive surgery into the treatment algorithm.

CivaSheet® use for soft tissue sarcoma: A single institution experience. Brachytherapy 2023; 22:649-654. [PMID: 37271655 DOI: 10.1016/j.brachy.2023.03.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Revised: 02/28/2023] [Accepted: 03/05/2023] [Indexed: 06/06/2023]
Abstract
OBJECTIVE CivaSheet is a palladium-103, implantable, intraoperative radiation therapy device which emits unidirectional radiation that enables boost doses in patients who have otherwise received the maximum radiation dose. Here, we present our initial clinical experience with the first 10 cases using this new technology. METHODS AND MATERIALS A retrospective chart review of all patients with STS treated with surgical resection and CivaSheet placement at the University of Miami Hospital, a tertiary care center, from January 2018 to December 2019, was performed. Adjuvant radiation was administered by a palladium-103 implant, which delivered an average of 47 Gy (35-55) to a depth of 5 mm. RESULTS Nine patients underwent CivaSheet placement from January 2018 until December 2019 for a total of 10 CivaSheets placed (1 patient had 2 CivaSheets inserted) and followed for a mean of 27 months (4-45 months). Four tumors were located in the retroperitoneum, two in the chest, two in the groin, and two within the lower extremity. At the time of tumor resection and CivaSheet placement, tumor sizes ranged from 2.5 cm to 13.8 cm with an average of 7.6 cm. Four patients necessitated musculocutaneous tissue flaps for closure and reconstruction. All patients with Grade 4 complications had flap reconstruction and prior radiation. Four patients' tumors recurred locally for a local recurrence rate of 40%. Three patients had modified accordion Grade 4 complications necessitating additional surgery for CivaSheet removal. Extremity tumors unanimously developed modified accordion Grade 4 adverse events. CONCLUSIONS CivaSheet may be an acceptable alternative treatment modality compared to prior brachytherapy methods.

Clin Oncol (R Coll Radiol) 2023:S0936-6555(23)00218-2. [PMID: 37344243 DOI: 10.1016/j.clon.2023.06.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 05/31/2023] [Accepted: 06/06/2023] [Indexed: 06/23/2023]
Abstract
Adjuvant radiotherapy is an integral component in the management of soft-tissue sarcomas. Brachytherapy is a very convenient and conformal way of delivering adjuvant radiotherapy in such tumours, which spares the surrounding normal tissue. Randomised studies have established the efficacy of brachytherapy in the adjuvant setting, with a 5-year local control of 80-85%. High dose rate, low dose rate and pulsed dose rate have shown equivalent local control, but high dose rate has gained popularity owing to patient convenience, radiation safety and flexibility in dose optimisation. Freehand insertion perioperative brachytherapy (intraoperative placement and postoperative treatment) is the most commonly used technique in soft-tissue sarcomas, with intraoperative radiotherapy and radioactive seed placement being the less commonly used techniques. Brachytherapy can be used as monotherapy or in combination with external beam radiotherapy, such as in cases of close/positive margins for safe dose escalation. Although the quantum of side-effects with external beam radiotherapy has considerably reduced with the evolution of technology and the introduction of intensity modulation (intensity-modulated radiotherapy), brachytherapy still scores better in terms of dose conformality, especially in recurrent tumours (previously irradiated) and when used to treat paediatric and geriatric patients.

Brachytherapy in the Treatment of Soft-Tissue Sarcomas of the Extremities-A Current Concept and Systematic Review of the Literature. Cancers (Basel) 2023; 15:cancers15041133. [PMID: 36831476 PMCID: PMC9954233 DOI: 10.3390/cancers15041133] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Revised: 02/02/2023] [Accepted: 02/06/2023] [Indexed: 02/12/2023] Open
Abstract
INTRODUCTION Evidence on the use of brachytherapy in soft-tissue sarcoma (STS) is sparse. Therapy regimens are determined more by local interdisciplinary tumor conferences than by standardized protocols. Patient-specific factors complicate the standardized application of therapy protocols. The individuality of the treatment makes it difficult to compare results. MATERIALS AND METHODS A comprehensive literature search was conducted, whereby the literature from a period of almost 44 years (1977-2021) was graded and included in this systematic review. For this purpose, PubMed was used as the primary database. Search string included "soft-tissue sarcoma", "brachytherapy", and "extremity." Four independent researchers reviewed the literature. Only full-text articles written in English or German were included. RESULTS Of the 175 identified studies, 70 were eligible for analysis based on the inclusion and exclusion criteria. The key points to compare were local complications, recurrence rate and correlation with margins of resection, and the use of brachytherapy regarding tumor grading. CONCLUSION Brachytherapy represents an important subset of radiotherapy techniques used in STSs, whose indications and applications are constantly evolving, and for which a local control rate of 50% to 96% has been reported as monotherapy, depending on risk factors. However, the best benefit is seen in the combination of further resection and brachytherapy, and most authors at many other centers agree with this treatment strategy.

Abstract
Radiation therapy is an integral component of local management with oncologic resection for soft tissue sarcoma. Radiotherapy is indicated in patients at an increased risk of local recurrence so that improved local control may be achieved. Sequencing of radiotherapy and resection should be determined by multidisciplinary input before treatment initiation. For most patients, preoperative delivery of radiation therapy is preferred. In patients initially thought to be at low risk for local recurrence and found to have unexpected adverse pathologic features at resection, postoperative radiation therapy is indicated. The use of radiation therapy for retroperitoneal sarcoma is controversial; when used, preoperative delivery of radiation is recommended.

Abstract
OBJECTIVE Compared with radical resection alone, perioperative radiation therapy (RT) combined with neurovascular preserving surgery is the standard for the management of virgin soft-tissue sarcomas. Yet, the optimal management of a local recurrence remains unclear. We report outcomes of patients with locally recurrent soft-tissue sarcoma treated with resection and reirradiation at the University of Florida. MATERIALS AND METHODS We reviewed the records of patients treated with primary conservative surgery and radiation for soft-tissue sarcoma followed by salvage resection and reirradiation for a local recurrence at our institution. RESULTS We analyzed 23 patients treated between 1976 and 2014 (median follow-up, 46 mo). Tumor sites included: proximal extremity, 11 patients; trunk, 6; distal extremity, 5; and head and neck, 1. All patients had conservative gross total resection of their recurrent tumor, without amputation. For reirradiation, 16 patients received external-beam RT alone, 6 received external-beam RT and brachytherapy, and 1 received brachytherapy alone. Two patients received chemotherapy. After retreatment, the 5-year overall survival, cause-specific survival, local control, and distant control rates were 39%, 42%, 46%, and 60%, respectively. Ten patients experienced local recurrences, 1 experienced regional recurrence, and 9 developed distant metastases. Retreatment-related complications ranged from delayed wound healing to limb amputation; 8 patients required amputation. Only 3 patients remained disease-free at last follow-up. No statistically significant associations were found between treatment factors (eg, RT dose) and local control. CONCLUSIONS Achieving local control of recurrent soft-tissue sarcoma is challenging. Treatment with reoperation and reirradiation can lead to debilitating complications affecting function and quality of life.

Abstract
Molecular alterations drive cancer initiation and evolution during development and in response to therapy. Radiotherapy is one of the most commonly employed cancer treatment modalities, but radiobiologic approaches for personalizing therapy based on tumor biology and individual risks remain to be defined. In recent years, analysis of circulating nucleic acids has emerged as a non-invasive approach to leverage tumor molecular abnormalities as biomarkers of prognosis and treatment response. Here, we evaluate the roles of circulating tumor DNA and related analyses as powerful tools for precision radiotherapy. We highlight emerging work advancing liquid biopsies beyond biomarker studies into translational research investigating tumor clonal evolution and acquired resistance.

Abstract
PURPOSE Growing data supports the role of radiation therapy in the treatment of soft tissue sarcoma (STS). Brachytherapy has been used for decades in the management of STS and can be utilized as monotherapy or as a boost to external beam radiation. We present updated guidelines from the American Brachytherapy Society regarding the utilization of brachytherapy in the management of STS. METHODS AND MATERIALS Members of the American Brachytherapy Society with expertise in STS and STS brachytherapy created an updated clinical practice guideline including step-by-step details for performing STS brachytherapy based on a literature review and clinical experience. RESULTS Brachytherapy monotherapy should be considered for lower-recurrence risk patients or after a local recurrence following previous external beam radiation; a brachytherapy boost can be considered in higher-risk patents meeting implant criteria. Multiple dose/fractionation regimens are available, with determination based on tumor location and treatment intent. Techniques to limit wound complications are based on the type of wound closure; wound complication can be mitigated with a delay in the start of brachytherapy with immediate wound closure or by utilizing a staged reconstruction technique, which allows an earlier treatment start with a delayed wound closure. CONCLUSIONS These updated guidelines provide clinicians with data on indications for STS brachytherapy as well as guidelines on how to perform and deliver high quality STS brachytherapy safely with minimal toxicity.

Abstract
Autologous fat grafting (AFG) serves as an effective method to address volume defects, contour irregularities, and asymmetry in both aesthetic and reconstructive procedures. In recent years, there has been growing concern about the potential of cancer recurrence and interference with cancer surveillance in oncologic patients receiving AFG. The adipose tissue contains adipose-derived stem cells (ASCs), a specific type of mesenchymal stem cells, that facilitate secretion of numerous growth factors which in turn stimulate tissue regeneration and angiogenesis. As such, it has been theorized that ASCs may also have the potential to stimulate cancer cell proliferation and growth when used in oncologic patients. Multiple research studies have demonstrated the ability of ACSs to facilitate tumor proliferation in animal models. However, clinical research in oncologic patients has yielded contradictory findings. Although the literature pertaining to oncologic safety in head and neck, as well as sarcoma, cancer patients remains limited, studies demonstrate no increased risk of tumor recurrence in these patient populations receiving AFG. Similarly, both the efficacy and safety of AFG have been well established in breast cancer patients through numerous clinical studies. More recently, preclinical research in animal models has shown that AFG has the potential to facilitate tissue regeneration and improve joint contracture following irradiation. Ultimately, further research is needed to elucidate the safety of AFG in a variety of oncologic patients, as well as explore its use in tissue regeneration, particularly in the setting of radiotherapy. Level of Evidence: 4.

Abstract
Local management of adult soft tissue sarcoma of the extremities has evolved over the past decades. Until the 1970s, radical surgery (amputations) was the standard therapeutic procedure resulting in significant physical and psychological morbidity for the patients. In the present era, limb sparing surgery combined with radiotherapy represents the current standard of care for high grade and > 5 cm STSs. This approach guarantees high local control rate and function preservation. The aim of this paper is to summarize the current evidence for RT in STSs of the extremities. Outcomes, technical details (techniques, timing, dose, volumes of treatment) and the emerging role of RT in the management of oligometastatic disease will be analysed. Finally, results of the recent clinical trials testing new scenarios in RT of STSs will be described.

Abstract
Background Soft-tissue sarcomas (STS) are rare tumors of the soft tissue. Recent diagnostic studies on STS mainly dealt with only few cases of STS and did not investigate the post-therapeutic performance of MRI in a routine clinical setting. Therefore, we assessed the long-term diagnostic accuracy of MRI for detecting recurrent STS at a multidisciplinary sarcoma center. Methods In all, 1055 postoperative follow-up MRIs of 204 patients were included in the study. MRI follow-up scans were systematically reviewed for diagnostic values (true-positive/−negative and false-positive/−negative results) in detecting recurrences. Pathological reports and follow-up MRIs were set as baseline references. Results The median age of the patients was 55.3 ± 18.2 years. Of the patients, 34.8% presented with recurrences. Here, 65 follow-up scans were true positive, 23 false positive, 6 false negative, and 961 true negative. The overall sensitivity and specificity of MRI for detecting recurrences were 92 and 98%, respectively, with an accuracy of 97%. For intramuscular lesions and after surgery alone the sensitivity was higher (95 and 97%, respectively) than for subcutaneous lesions and surgery with additional radiation therapy (83 and 86%, respectively), at similarly high specificities (96–98%). The 6 false-negative results were found in streaky (n = 2) and small ovoid/nodular (n = 4) recurring lesions. The false-positive lesions imitated streaky (n = 14), ovoid/nodular (n = 8), and polycyclic/multilobulated recurring tumors (n = 1). All false-positive results were found in patients in whom the primary tumors were polycyclic/multilobulated in appearance. Conclusion MRI shows a high diagnostic accuracy for detecting recurrent STS, with a high sensitivity and specificity. The diagnostic accuracy decreases in subcutaneous lesions and after surgery with radiation therapy, compared to intramuscular lesions and surgery alone. Radiologists should pay particular attention to streaky and small ovoid/nodular recurring lesions and patients with polycyclic/multilobulated primary tumors.

Abstract
Background This novel study compared the use of tumor necrosis factor (TNF)-alpha and melphalan-based isolated limb perfusion (TM-ILP) to the standard treatment of locally recurrent soft tissue extremity sarcoma. The aim was to assess whether TM-ILP positively influences the recurrence-free survival of locally recurrent high-grade soft tissue sarcoma (STS) of the extremities. Methods We retrospectively analyzed our clinical database for patients with STS. Variables were analyzed using chi-square test or Mann-Whitney rank-sum test. Furthermore, Kaplan-Meier survival plots were calculated and a proportional hazard regression model was developed. Results Out of 448 patients with extraabdominal STS treated between August 2012 and December 2015, 52 cases involving 47 patients had locally recurrent STS. Twenty-eight of these patients were treated with TM-ILP prior to surgical resection (TM-ILP-group), and 24 were treated with standard therapy (without TM-ILP). The 3-year recurrence-free survival for the TM-ILP-group was estimated at 75% (95% confidence interval (CI), 71.5–78.5). Local recurrence-free survival in the standard group was significantly lower (LRFS: 43.4%, 95% CI 38.7–48.1, p = 0.026). Multivariable analysis revealed resection with negative margins, lower number of previous recurrences, and TM-ILP as positive predictors for recurrence-free survival. Conclusions TM-ILP and consecutive resection of residual tumor with negative resection margins significantly improves local recurrence-free survival for patients with a first local recurrence of high-grade STS in the extremities.

Radiation Therapy in Adult Soft Tissue Sarcoma-Current Knowledge and Future Directions: A Review and Expert Opinion. Cancers (Basel) 2020; 12:cancers12113242. [PMID: 33153100 PMCID: PMC7693687 DOI: 10.3390/cancers12113242] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2020] [Revised: 10/28/2020] [Accepted: 10/29/2020] [Indexed: 12/13/2022] Open
Abstract
Simple Summary Radiation therapy (RT) is an integral part of the treatment of adult soft-tissue sarcomas (STS). Although mainly used as perioperative therapy to increase local control in resectable STS with high risk features, it also plays an increasing role in the treatment of non-resectable primary tumors, oligometastatic situations, or for palliation. This review summarizes the current evidence for RT in adult STS including typical indications, outcomes, side effects, dose and fractionation regimens, and target volume definitions based on tumor localization and risk factors. It covers the different overall treatment approaches including RT either as part of a multimodal treatment strategy or as a sole treatment and is accompanied by a summary on ongoing clinical research pointing at future directions of RT in STS. Abstract Radiation therapy (RT) is an integral part of the treatment of adult soft-tissue sarcomas (STS). Although mainly used as perioperative therapy to increase local control in resectable STS with high risk features, it also plays an increasing role in the treatment of non-resectable primary tumors, oligometastatic situations, or for palliation. Modern radiation techniques, like intensity-modulated, image-guided, or stereotactic body RT, as well as special applications like intraoperative RT, brachytherapy, or particle therapy, have widened the therapeutic window allowing either dose escalation with improved efficacy or reduction of side effects with improved functional outcome. This review summarizes the current evidence for RT in adult STS including typical indications, outcomes, side effects, dose and fractionation regimens, and target volume definitions based on tumor localization and risk factors. It covers the different overall treatment approaches including RT either as part of a multimodal treatment strategy or as a sole treatment, namely its use as an adjunct to surgery in resectable STS (perioperative RT), as a primary treatment in non-resectable tumors (definitive RT), as a local treatment modality in oligometastatic disease or as palliative therapy. Due to the known differences in clinical course, general treatment options and, consequently, outcome depending on lesion localization, the main part of perioperative RT is divided into three sections according to body site (extremity/trunk wall, retroperitoneal, and head and neck STS) including the discussion of special applications of radiation techniques specifically amenable to this region. The review of the current evidence is accompanied by a summary on ongoing clinical research pointing at future directions of RT in STS.

Intraoperative Localization Using an Implanted Radar Reflector Facilitates Resection of Non-Palpable Trunk and Extremity Sarcoma. Ann Surg Oncol 2020; 28:3366-3374. [PMID: 33073344 DOI: 10.1245/s10434-020-09229-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2020] [Accepted: 09/23/2020] [Indexed: 12/27/2022]
Abstract
BACKGROUND Resecting non-palpable soft tissue tumors presents a unique challenge, particularly with recurrent disease in which surrounding tissue has been surgically manipulated and often irradiated. SAVI SCOUT® is a radar-based localization device that was developed for breast tumor localization and was recently FDA-approved for localization of soft tissue tumors. Application of this technology to soft tissue sarcoma has not been previously reported. METHODS We assembled a single-institution retrospective case series of patients with trunk and extremity sarcomas resected by five sarcoma surgeons using SAVI SCOUT® from December 2018 to May 2020. Reflectors were placed preoperatively using image-guidance, and the radar detector was used intraoperatively to localize the target lesion. Clinical variables were abstracted from the electronic medical record including treatment history, pathology, and early oncologic outcomes. Using a focused review, we compared margin status and recurrence rates with previously published cohorts. RESULTS Ten SAVI SCOUT®-localized sarcoma resections were performed. Eight were for locally recurrent disease, of which seven (83%) had prior radiation. The remaining lesions became non-palpable after neoadjuvant chemotherapy. SAVI SCOUT® facilitated resection in all cases with a margin-negative resection rate (77%) comparable to prior cohorts. In this high-risk population with a median follow-up of 14 months, only one patient recurred locally 7.5 months after SAVI SCOUT®-localized resection, requiring re-resection. CONCLUSION SAVI SCOUT® technology facilitated resection of non-palpable recurrent sarcoma of the trunk and extremities in all ten cases attempted. In a high-risk patient population, the pattern of recurrence has been primarily distant with one instance of local tumor recurrence.

Abstract
BACKGROUND/AIM Local recurrence in soft tissue sarcoma (STS) is a risk factor of worse prognosis. Although a few studies have shown that adjuvant therapy with acridine orange (AO) is effective for local control of primary STS, there have been no reports examining its effectiveness for local recurrence. PATIENTS AND METHODS This retrospective study included 36 patients with first local recurrence of STS. Of them, 23 patients received wide excision without AO therapy (Wide group); the other 13 patients received marginal excision with AO therapy (AO group). We compared re-recurrence rates between these two groups. RESULTS The total re-recurrence rate was 43.5% in the Wide group and 46.2% in the AO group. There was no significant difference in local re-recurrence-free survival and overall survival between the two groups. CONCLUSION Adjuvant AO therapy combined with a marginal excision suppresses local re-recurrence rates of individuals with local STS recurrence.

Efficacy and safety of CT-guided 125I seed implantation as a salvage treatment for locally recurrent head and neck soft tissue sarcoma after surgery and external beam radiotherapy: A 12-year study at a single institution. Brachytherapy 2019; 19:81-89. [PMID: 31653566 DOI: 10.1016/j.brachy.2019.09.006] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2019] [Revised: 08/20/2019] [Accepted: 09/09/2019] [Indexed: 11/16/2022]
Abstract
OBJECTIVES The objective of this study was to evaluate the efficacy and safety of CT-guided radioactive 125I seed implantation as a salvage treatment for locally recurrent head and neck soft tissue sarcoma (HNSTS) after surgery and external beam radiotherapy. METHODS AND MATERIALS From December 2006 to February 2018, 25 patients with locally recurrent HNSTS after surgery and external beam radiotherapy were enrolled. All the patients successfully underwent CT-guided 125I seed implantation. The primary end points included the objective response rate (ORR) and local progression-free survival (LPFS). The secondary end points were survival (OS) and safety profiles. RESULTS After 125I seed implantation, the ORR was 76.0%. The 1-, 3-, and 5-year LPFS rates were 65.6%, 34.4%, and 22.9%, respectively, with the median LPFS of 16.0 months. The 1-, 3-, and 5-year OS rates were 70.8%, 46.6%, and 34.0%, respectively, with the median OS of 28.0 months. Furthermore, univariate analyses showed that the recurrent T stage and histological grade were prognostic factors of LPFS, whereas only the histological grade was a predictor of OS. The major adverse events were skin/mucosal toxicities, which were generally of lower grade (≤Grade 2) and were well tolerated. CONCLUSIONS Radioactive 125I seed implantation could be an effective and safe alternative treatment for locally recurrent HNSTS after failure of surgery and radiotherapy. Recurrent T stage and histological grade were the main factors influencing the efficacy.

Novel intraoperative radiotherapy utilizing prefabricated custom three-dimensionally printed high-dose-rate applicators. Brachytherapy 2019; 18:277-284. [PMID: 30803923 DOI: 10.1016/j.brachy.2019.01.012] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2018] [Revised: 01/27/2019] [Accepted: 01/30/2019] [Indexed: 11/21/2022]
Abstract
BACKGROUND Intraoperative radiotherapy (IORT) is an effective strategy for the delivery of high doses of radiotherapy to a residual tumor or resection cavity with relative sparing of nearby healthy tissues. This strategy is an important component of the multimodality management of pediatric soft tissue sarcomas, particularly in cases where patients have received prior courses of external beam radiotherapy. PURPOSE Tumor beds with significant topographic irregularity remain a therapeutic challenge because existing IORT technologies are typically most reliable with flat surfaces. To address this limitation, we have developed a novel strategy to create custom, prefabricated high-dose-rate (HDR)-IORT applicators designed to match the shape of an anticipated surgical cavity. METHODS AND MATERIALS Silastic applicators are constructed using three-dimensional (3D) printing and are derived from volumetric segmentation of preoperative imaging. RESULTS HDR preplanning with the applicators improves dosimetric accuracy and minimizes incremental operative time. In this report, we describe the fabrication process for the 3D-printed applicators and detail our experience utilizing this strategy in two pediatric patients who underwent HDR-IORT as part of complex base of skull sarcoma resections. CONCLUSIONS Early experience suggests that usage of the custom applicators is feasible, versatile for a variety of clinical situations, and enables the uniform delivery of high superficial doses of radiotherapy to irregularly shaped surgical cavities.

Abstract
Background Patients with recurrent retroperitoneal and pelvic region tumors often require multimodal therapies. Intraoperative radiation therapy (IORT) can deliver high-dose radiation to tumor beds, even if first-line external beam radiation therapy (EBRT) was administered. We evaluated local control (LC) and survival in patients receiving IORT for recurrent tumors. Methods We retrospectively analyzed 41 patients with isolated pelvic or retroperitoneal recurrences of colorectal, gynecological, or retroperitoneal primary tumors. Following salvage surgery, all patients underwent tumor bed IORT via electron beam or high dose rate brachytherapy. Isolated IORT (median dose: 15 Gy) was administered to patients who had received first-line EBRT; other patients received IORT (median dose 12 Gy) plus EBRT. Local (LF), regional (RF), and distant failures (DF) were evaluated, and the Kaplan–Meier method and log-rank test were used to evaluate and compare overall survival (OS) from the date of IORT. Results Forty-one patients underwent 44 treatments, including 27 (61.3%) isolated IORT and 17 (38.7%) IORT and EBRT combination regimens. The median follow-up was 8.1 years (range: 4.4–11.7 years), and the 2, 5, and 8 year overall LC rates were 87.9, 64.0, and 49.8%, respectively. Regarding resection status, the respective 2, 5, and 8 year LC rates were 90, 76, and 76% for R0 resection and 75, 25, and 0% for R1 resection (p < 0.001). The 2, 5, and 8 year OS rates were 68, 43, and 26%, respectively. OS was better among patients with LC (p < 0.001). Twenty-four patients (58.5%) experienced a DF, and the 5 year OS rates for the patients with and without DF were 36 and 52%, respectively (p = 0.04). In a multivariate analysis, LF (p = 0,012) and recurrent retroperitoneal sarcoma (p = 0,014) were identified as significant predictors of worse OS. Thirteen patients (31%) developed clinically treatable complications related to IORT. Conclusions Many patients achieve long-term OS and LC without significant morbidity after salvage surgery and IORT, especially in case of clear margins.

Abstract
BACKGROUND Recurrence after wide excision or residual tumor after an unplanned excision of a malignant soft tissue sarcoma (STS) is a complex problem, due to a higher recurrence rate and poorer survival rate compared with primary resection. Regional hyperthermia was used, with the expectation that it will enhance the anti-tumor effects of chemotherapy and radiotherapy. This study aimed to assess the efficacy of neoadjuvant concomitant radiotherapy, hyperthermia, and chemotherapy (RHC) for salvage of recurrent or residual malignant STS. METHODS We identified 64 patients with recurrent or residual STS treated between 1994 and 2013. After excluding those with low-grade malignancy, with recurrent bone tumor in the soft tissues, with truncal STS, and who declined to participate, 23 patients (7 with recurrence and 16 with residual tumor) underwent RHC. The histologic diagnoses were undifferentiated pleomorphic sarcoma (n = 11), synovial sarcoma (n = 3), leiomyosarcoma and myxoid liposarcoma (n = 2 each), and other histologic types. As primary outcomes, the 5-year overall survival (OS), distant metastasis-free survival (D-MFS), and local control (LC) rates were evaluated by Kaplan-Meier analysis. RESULTS The median follow-up period was 112.3 months. The 5-year OS, D-MFS, and LC were 86.4%, 77.4%, and 86.7%, respectively. In the univariate analysis, tumor depth was considered as a negative prognostic factor for OS and D-MFS, and a positive margin was also a negative prognostic factor for OS, D-MFS LC with retained on Cox proportional hazards model in OS, and D-MFS. CONCLUSION RHC is an effective option for salvage treatment of recurrent and residual STS.

What Is the Success of Repeat Surgical Treatment of a Local Recurrence After Initial Wide Resection of Soft Tissue Sarcomas? Clin Orthop Relat Res 2018; 476:1791-1800. [PMID: 30794216 PMCID: PMC6259807 DOI: 10.1007/s11999.0000000000000158] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/31/2023]
Abstract
BACKGROUND Treatment for patients with locally recurrent soft tissue sarcomas after wide resection is challenging, and few studies have examined the results of treating these patients. In treatment of recurrent tumors, it has been reported that positive margins are correlated to local rerecurrence, but the relationship between surgical margin and survival remains controversial and risk factors for local recurrences after wide resection of soft tissue sarcomas are not well established. This study examined clinical outcomes and factors associated with survival and local rerecurrence in patients with local recurrence after initial surgical treatment who underwent another resection with a goal of negative margins. QUESTIONS/PURPOSES The purpose of this study was to determine (1) oncologic outcomes (survival rates and local rerecurrence-free rates) of surgical treatment for patients with local recurrence after wide resection; (2) whether factors associated with survival and local rerecurrence-free rates can be determined; and (3) the proportion of patients treated by amputation at final followup. METHODS Between 1992 and 2013, we treated 530 patients with soft tissue sarcoma without metastasis. Of those, 26 (5%) were lost before 3 years of followup but were not known to have died. Of the remainder, 59 have had a local recurrence. Of those with a local recurrence, 34 (58%) were treated with wide resection, whereas 25 (42%) were treated with nonsurgical treatment including chemotherapy and radiotherapy. During that period, our general indications for wide resection were patients (1) without distant metastasis; or (2) without distant lymph node metastasis, and contraindications were distant organ metastasis and/or distant lymph node metastasis. Of those treated with wide resection, 30 (88%) were available for followup. We conducted a retrospective analysis of these 30 patients with local recurrence (17 men, 13 women) who had previously undergone wide resection. Patient followup ranged from 1 to 12 years (median, 5 years). Survivorship (including overall survival and survival free from repeat recurrence) was ascertained by the Kaplan-Meier method. Factors associated with survival were evaluated by the log-rank test. Amputations were performed when limb-sparing surgery was deemed unsuitable because of extensive involvement of the limb by tumor, including invasion of multiple muscle compartments and neurovascular components. Survivorship free from amputation was ascertained by the Kaplan-Meier method. RESULTS Overall 5- and 10-year Kaplan-Meier survival rates after resection were 70% (95% confidence interval [CI], 50%-91%) and 44% (95% CI, 12%-76%), respectively, and 12 patients (40%) developed distant metastases after the second operation. Ten patients (33%) had additional local recurrences, and overall 5- and 10-year local rerecurrence-free rates were 66% (95% CI, 48%-85%) and 50% (95% CI, 18%-81%), respectively. A positive margin was associated with further recurrence (5-year local rerecurrence-free rates of positive margin: 20% [95% CI, 0%-52%], negative margin: 89% [95% CI, 74%-100%], p < 0.01) and with survival (5-year survival rates of positive margin: 36% [95% CI, 0%-75%], negative margin: 91% [95% CI, 74%-100%], p < 0.01). The survival rate was lower in patients with recurrence developing after 2 years (5-year survival rates of within 2 years: 46% [95% CI, 2%-90%], after 2 years: 83% [95% CI, 62%-100%], p = 0.01). The overall 5- and 10-year amputation-free rates were 86% (95% CI, 74%-99%) and 81% (95% CI, 67%-96%), respectively. CONCLUSIONS A surgical procedure with negative margins appears to be important for reducing the likelihood of local recurrences and improving survival of patients with rerecurrence after wide resection of soft tissue sarcomas. Although these findings need to be confirmed in larger studies, it appears that when tumor recurrence is evident within 2 years from the primary surgery, it is associated with a poor prognosis. Local recurrence within 2 years after wide resection may also be an indicator of aggressive tumor biology. LEVEL OF EVIDENCE Level IV, therapeutic study.

Abstract
Purpose To evaluate the feasibility of stereotactic body radiation therapy (SBRT) for unresectable soft tissue tumors of the trunk. Materials and Methods Between January 2002 and December 2008, 23 patients with 36 lesions of soft tissue tumors, which were located in the trunk and not suitable for resection, underwent SBRT. Among the 36 lesions, 31 were malignant and 5 were benign. The median tumor volume was 24 cm3 (range, 2.6–213 cm3). SBRT doses ranged from 20 to 48 Gy in 1–5 fractions. Results With a median follow-up of 73 months, the overall survival (OS) and local control (LC) rates at 5 years were 39% and 52%, respectively. For malignant tumors, the OS and LC rates at 5 years were 28% and 47%, respectively. For benign tumors, the OS and LC rates at 5 years were 80% and 100%, respectively. There was no acute toxicity of grade ≥3. One case of grade 3 late skin toxicity was reported 10 months after SBRT. Conclusion SBRT may be an effective and safe treatment modality for the local control of unresectable soft tissue tumors of the trunk including tumors of a benign nature.

Staged reconstruction brachytherapy has lower overall cost in recurrent soft-tissue sarcoma. J Contemp Brachytherapy 2017; 9:20-29.

Abstract
Purpose Adjuvant brachytherapy (AB) with immediate (IR) and staged reconstruction (SR) are distinct treatment modalities available for patients with recurrent soft tissue sarcoma (STS). Although SR may offer local control and toxicity benefit, it requires additional upfront procedures, and there is no evidence that it improves overall survival. With the importance of value-based care, our goal is to identify which technique is more cost effective. Material and methods A retrospective review of 22 patients with recurrent extremity STS treated with resection followed by AB alone. Hospital charges were used to compare the cost between SR and IR at the time of initial treatment, at 6-month intervals following surgery, and cumulative cost comparisons at 18 months. Results Median follow-up was 31 months. Staged reconstruction (n = 12) was associated with an 18-month local control benefit (85% vs. 42%, p = 0.034), compared to IR (n = 10). Staged reconstruction had a longer hospital stay during initial treatment (10 vs. 3 days, p = 0.002), but at 18 months, the total hospital stay was no longer different (11 vs. 11 days). Initially, there was no difference in the cost of SR and IR. With longer follow-up, cost eventually favored SR, which was attributed primarily to the costs associated with local failure (LF). On multivariate analysis, cost of initial treatment was associated with length of hospital stay (~$4.5K per hospital day, p < 0.001), and at 18 months, the cumulative cost was ~175K lower with SR (p = 0.005) and $58K higher with LF (p = 0.02). Conclusions In recurrent STS, SR has a longer initial hospital stay when compared to IR. At 18 months, SR had lower rates of LF, translating to lower total costs for the patient. SR is the more cost-effective brachytherapy approach in the treatment of STS, and should be considered as healthcare transitions into value-based medicine.

Abstract
The management of recurrent soft tissue sarcoma is a challenging problem for clinicians and has a significant physical, mental, emotional, and oncologic impact for the patient. Despite excellent limb-preservation therapies, approximately one-quarter of patients may eventually develop recurrence of disease. How to most appropriately manage these patients is a matter of debate. Several treatment options exist, including surgical resection, irradiation, systemic chemotherapy, amputation, and regional therapies. This article highlights the management of recurrent extremity soft tissue sarcoma.

Abstract
Soft tissue sarcomas are rare mesenchymal cancers that pose a treatment challenge. Although small superficial soft tissue sarcomas can be managed by surgery alone, adjuvant radiotherapy in addition to limb-sparing surgery substantially increases local control of extremity sarcomas. Compared with postoperative radiotherapy, preoperative radiotherapy doubles the risk of a wound complication, but decreases the risk for late effects, which are generally irreversible. For retroperitoneal sarcomas, intraoperative radiotherapy can be used to safely escalate the radiation dose to the tumor bed. Patients with newly diagnosed sarcoma should be evaluated before surgery by a multidisciplinary team that includes a radiation oncologist.

Abstract
PURPOSE Prior studies illustrated a reduction in wound complications with the use of staged reconstruction (SR) and negative pressure wound therapy when treating soft tissue sarcoma (STS) with surgical resection followed by high-dose-rate adjuvant brachytherapy. The purpose of this study is to compare the outcomes of SR and immediate reconstruction (IR) brachytherapy in recurrent STS. METHODS AND MATERIALS A retrospective review of 40 patients with recurrent STS of the local extremity and trunk treated with resection followed by adjuvant brachytherapy alone. Margin status was defined as positive (SM(+)) if there was microscopic involvement (R1) or ≤1 mm margin and negative (SM(-)) if >1 mm margin was obtained. SR and IR were compared regarding toxicity, local control, and limb preservation. RESULTS Median followup was 27 months. When comparing the SR (n = 22) and IR (n = 18) cohorts, there was a significantly lower final SM(+) rate in SR (32% vs. 83%, p < 0.01). A 2-year local control benefit seen with SR (80% vs. 34%; p = 0.012) and a final SM(-) (81% vs. 39%; p = 0.023). SR was associated with less toxicity on multivariate analysis, including a 90% decrease in persistent edema, an 80% decrease in wound dehiscence, and a 94% decrease in nonhealing wounds, when compared to IR. Ten of 31 (32%) extremity cases required eventual amputation from either chronic wound complications (n = 4) or local recurrence (n = 6). SR predicted for a benefit in 2-year limb preservation (88% vs. 50%; p = 0.008). CONCLUSION In our series, the treatment with SR brachytherapy resulted in less morbidity and an improved final SM(-) rate. This technique translated to an improvement in both local control and limb preservation of recurrent STS.

Intraoperative Radiotherapy in the Management of Locally Recurrent Extremity Soft Tissue Sarcoma. Sarcoma 2015; 2015:913565.

Abstract
Purpose. To investigate the efficacy and morbidity of limb-sparing surgery with intraoperative radiotherapy (IORT) for patients with locally recurrent extremity soft tissue sarcoma (ESTS). Methods and Materials. Twenty-six consecutively treated patients were identified in a single institution retrospective analysis of patients with locally recurrent ESTS treated with IORT following salvage limb-sparing resection from May 2000 to July 2011. Fifteen (58%) patients received external beam radiotherapy (EBRT) prior to recurrence (median dose 63 Gy), while 11 (42%) patients received EBRT following IORT (median dose 52 Gy). The Kaplan-Meier product limit method was used to estimate disease control and survival and subsets were compared using a log rank statistic, Cox's regression model was used to determine independent predictors of disease outcome, and toxicity was reported according to CTCAE v4.0 guidelines. Results. With a median duration of follow-up from surgery and IORT of 34.9 months (range: 4 to 139 mos.), 10 patients developed a local recurrence with 4 subsequently undergoing amputation. The 5-year estimate for local control (LC) was 58% (95% CI: 36–75%), for amputation-free was 81% (95% CI: 57–93%), for metastasis-free control (MFC) was 56% (95% CI: 31–75%), for disease-free survival (DFS) was 35% (95% CI: 17–54%), and for overall survival (OS) was 50% (95% CI: 24–71%). Prior EBRT did not appear to influence disease control (LC, p = 0.74; MFC, p = 0.66) or survival (DFS, p = 0.16; OS, p = 0.58). Grade 3 or higher acute and late toxicities were reported for 6 (23%) and 8 (31%) patients, respectively. The frequency of both acute and late grade 3 or higher toxicities occurred equally between patients who received EBRT prior to or after IORT. Conclusions. IORT in combination with oncologic resection of recurrent ESTS yields good rates of local control and limb-salvage with acceptable morbidity. Within the limitations of small subsets, these data suggest that prior EBRT does not significantly influence disease control or toxicity.

Abstract
For nearly half a decade, surgery and radiation therapy have been used in combination to achieve the goal of limb preservation in extremity soft tissue sarcoma, with success rates in excess of 90%. Common decision points in therapeutic radiation delivery for sarcoma are discussed, including preoperative versus postoperative irradiation, the postoperative boost, and when irradiation might be unnecessary. We describe specialized techniques, such as brachytherapy and intraoperative irradiation. The data driving current practice is summarized.

Abstract
OBJECTIVE The aim of the present retrospective study was to report on the effectiveness of the negative pressure wound therapy (NPWT) in the treatment of infected wounds after musculoskeletal tumour surgery. METHOD A total of 12 patients (10 male, 2 female, mean age 44.9 years with 9 early and 3 late infections) were included in the study. Patient parameters measured include age, gender, tumour diagnosis and localisation, pathogen organism, foam used, pressure height and modus, number of NPWT dressings changes, total duration of NPWT, need for secondary wound closure, length of hospitalisation, complications, and follow-up. RESULTS The NPWT dressings were changed on average 6.7 (SD±6.9) times after a mean duration of 5.6 (SD±2.4) days. The total duration of NPWT was 37.7 (SD±32.9) days. The mean hospital stay was 77.5 (SD±58.8) days. In 7 out of 12 cases, a split-thickness skin graft transplantation was performed. In these cases, no seroma or hematoma formation beneath the skin graft could be observed. At a mean follow-up 39.2 (range: 9-73) months, no reinfection or infection persistence was apparent. CONCLUSION NPWT can be of valuable assistance in the treatment of infected wounds following musculoskeletal tumour surgery. The patients should be informed about the long treatment period.

Abstract
BACKGROUND Patients with local recurrence of soft tissue sarcomas are predisposed to future recurrences because treatment is challenging and complicated by prior therapy. This study investigated clinical outcomes following surgical procedures for locally recurrent soft tissue sarcomas and risk factors for re-recurrence and metastasis. METHODS A retrospective analysis was conducted with 105 patients (52 males, 53 females) who underwent surgical procedures for local recurrence without distant metastasis of soft tissue sarcoma between 1987 and 2009. Patient follow-up ranged from 1 to 12 years (mean 4.9 years). RESULTS Overall 5- and 10-year survival rates were 83.4 and 67.7%, respectively. Twenty-one patients (20.0%) had additional local recurrences, and 23 (21.9%) had distant metastases. Amputation rate was 10.5% at the time of surgical procedures and 17.1% at final follow-up. Locations deep within muscles in the upper limb or trunk and surgical margins <1 cm wide were risk factors for further local recurrence. Locations deep within muscles, tumor sizes >10 cm, high-grade malignancy, and local recurrence after radical surgery were risk factors for distant metastasis. CONCLUSIONS Surgical margin and location were independent prognostic factors for local control, and a wider margin was especially important for recurrent tumors located in the trunk and upper extremity. For high-grade sarcomas with local recurrence after radical surgery, new approaches are needed to prevent distant metastases.

Abstract
PURPOSE To present recommendations for the use of brachytherapy (BT) in patients with soft tissue sarcoma (STS). METHODS A group of practitioners with expertise and experience in sarcoma BT formulated recommendations for BT in STS based on clinical experience and literature review. RESULTS The indications for adjuvant BT are discussed. There is no consensus on the use of BT alone or in combination with external beam radiation therapy (EBRT), but factors that influence the selection of this modality include tumor grade and size, prior surgeries, and tumor recurrence. Low-dose-rate, high-dose-rate, and pulsed-dose-rate radiation are all acceptable BT modalities to use for STS. Recommendations are made for patient selection, techniques, dose rates, and dosages. Outcome data and toxicity data are reviewed. CONCLUSIONS BT is a useful component of the treatment of STS. The advantages of BT are the targeted dose distribution, low integral dose, and short treatment times. Ultimately the clinician should select the modality or combination of modalities that are most familiar to the treatment team and suitable to the patient.

Abstract
PURPOSE To develop a nomogram based on clinicopathologic factors to quantify the risk of local recurrence (LR) after limb-sparing surgery without adjuvant radiation (RT). METHODS Review of our prospective sarcoma database identified 684 patients with primary, nonmetastatic, extremity STS treated with limb-sparing surgery alone between June 1982 and December 2006. No patient received adjuvant radiation or chemotherapy. Age, sex, grade, depth, size, site, margin status and histology were analyzed for prognostic significance with respect to local recurrence rates using Gray's test. Variables which were significant in univariate analysis at the 0.05 level were entered into a multivariate competing risk regression model. On the basis of the multivariate analysis, a nomogram for predicting the 3- and 5-year risk of LR was developed using R libraries cmprsk and QHScrnomo. Concordance index (C-index) was calculated to evaluate the discriminatory power of the prognostic model. RESULTS With a median follow-up of 58 months for censored patients (73 months for all patients), the overall 3- and 5-year actuarial local recurrence rates were 11% and 13%, respectively. Factors included in the nomogram were age (≤ 50 vs. >50), size (≤ 5 vs. >5 cm), margin status (negative vs. positive), grade (low vs. high), and histology (atypical lipomatous tumor/well differentiated liposarcoma vs. other). The STS nomogram predicted the local recurrence rate with a C-index of 0.73. CONCLUSIONS A nomogram for extremity STS that includes age, size, margin status, grade of tumor, and histology predicts the 3- and 5-year risk of local recurrence after limb-sparing surgery in the absence of adjuvant RT.

Abstract
BACKGROUND Sarcomas in irradiated tissue (SITs) are often considered with second cancers, although they usually present distinct dose-response, genetic and clinical patterns. The contribution of radiation in SIT development is likely, but remains unproven in many cases. MATERIALS AND METHODS We reviewed the literature for published data on SITs. RESULTS SITs incidence ranged between 0.03% and 0.2%. Median latency was 15 years. Angiosarcoma was the second most common subtype after undifferentiated sarcomas of malignant fibrous histiocytoma (MFH). C-Myc overexpression can be used to identify radiation-induced angiosarcoma, and a recently described transcriptomic signature of genes involved in chronic oxidative stress and mitochondrial dysfunction may indicate radiation causality. Osteosarcomas were often associated with genetic predisposition. Five-year survival rates rarely exceeded 30% because the therapeutic possibilities were often limited by the first cancer. Chemotherapy response may differ from that of de novo sarcomas. CONCLUSION SITs present different characteristics from non-sarcomatoid second cancers. Reporting of SIT cases and the establishment of tissue and serum banks is necessary to better understand and validate the recently discovered radiation signature.

Abstract
Purpose Adjuvant high-dose-rate brachytherapy (HDRBT) offers advantages over low dose rate brachytherapy (LDRBT), although there are little data on local tumor control and treatment related toxicity. We report outcome in patients with primary, recurrent, and metastatic extremity and superficial trunk soft tissue sarcoma. Material and methods Eleven patients (12 sites) with intermediate or high grade sarcoma were treated with adjuvant HDRBT following surgical resection. Patients were treated at 3.4 Gy fractions delivered twice daily to a total dose of 34 Gy (1 patient received 9 fractions). Results With median follow-up of 20.8 months, 1 patient developed a local recurrence. 2-year local control and overall survival are 89% and 71%, respectively. Wound complications occurred in 3 sites. Two of the wound complications developed in the area of previous external beam radiotherapy (EBRT). Conclusion Surgical resection followed by HDRBT is associated with excellent early local tumor control and acceptable wound complication.

Abstract
BACKGROUND Multimodality treatment of primary soft tissue sarcoma by expert teams reportedly affords a low incidence of local recurrence. Despite advances, treatment of local recurrence remains difficult and is not standardized. QUESTIONS/PURPOSES We (1) determined the incidence of local recurrence from soft tissue sarcoma; (2) compared characteristics of the recurrent tumors with those of the primary ones; (3) evaluated local recurrences, metastases and death according to treatments; and (4) explored the relationship between the diagnosis of local recurrence and the occurrence of metastases. METHODS From our prospective database, we identified 618 soft tissue sarcomas. Thirty-seven of the 618 patients (6%) had local recurrence. Leiomyosarcoma was the most frequent diagnosis (eight of 37). The mean delay from original surgery was 22 months (range, 2-75 months). Mean size was 4.8 cm (range, 0.4-28.0 cm). Median followup after local recurrence was 16 months (range, 0-98 months). RESULTS Recurrent tumors had a tendency toward becoming deeper seated and higher graded. Nineteen of the 37 patients with recurrence underwent limb salvage (nine free flaps) and six had an amputation. Twenty-two (59%) had metastases, including 10 occurring after the local recurrence event at an average delay of 21 months (range, 1-34 months). Six patients developed additional local recurrences, with no apparent difference in risk between amputation (two of six) and limb salvage (four of 19). CONCLUSIONS Patients with a local recurrence of a soft tissue sarcoma have a poor prognosis. Limb salvage and additional radiotherapy remain possible but with substantial complications. Amputation did not prevent additional local recurrence or death.

Abstract
Soft-tissue sarcoma (STS) is a histopathologically diverse group of tumors accounting for approximately 10,000 new malignancies in the US each year. The proximal lower extremity is the most common site for STS, accounting for approximately one-third of all cases. Coordinated multimodality management in the form of surgery and radiation is often critical to local control, limb preservation, and functional outcome. Based on a review of currently available Medline literature and professional experience, this paper provides an overview of the treatment of STS of the lower extremity with a particular focus on the modern role of radiotherapy.

Abstract
Soft-tissue sarcomas are a heterogeneous group of tumors consisting of approximately 100 distinct diagnoses. Management requires a multimodality approach with the input of pathologists, surgeons, radiation oncologists, medical oncologists and radiologists. In localized disease, the primary modality of treatment is wide-resection surgery, and the use of radiation therapy has improved local control rates for high-grade tumors. Currently, most localized tumors can be managed with limb-sparing treatment, and local control rates of 80-90% can be seen with appropriate management. Improvements in classification and diagnosis of these tumors have led to the current idea that the specific histology is an important consideration when developing a treatment plan and may affect prognosis, although existing staging systems have not yet incorporated this parameter. Treatment of metastatic disease continues to be difficult, but current research focuses on clarifying molecular mechanisms of disease and identifying new potential targets for medical therapy. This review focuses on the current status of management of these tumors including a review of epidemiology, initial evaluation, and treatment including surgical, radiation, and medical aspects.

Abstract
BACKGROUND Adult soft tissue sarcomas (STS) of extremities are prone to recurrence despite apparently complete resection. This study aimed to explore the impact of clinicopathological factors on outcome and to define an "oncological safe margin" in these patients. METHODS A total of 181 patients with extremity STS were enrolled in a retrospective study. The prognostic influence of margin status and other clinicopathological characteristics on local recurrence-free survival (LRFS), distant metastasis-free survival (DMFS), and disease-specific survival (DSS), were examined by univariate and multivariate analyses. The influence of surgical margins on postrecurrence survival (PRS) of patients undergoing reoperation for relapsed lesions during follow-up was analyzed by the Kaplan-Meier method. RESULTS Surgical margin width <10 mm and deep tumor depth at primary operation were consistently statistically significant independent adverse factors for LRFS, DMFS, and DSS. Patients with liposarcoma or low grade tumors had significantly higher chances of achieving adequate margins. Of 83 patients who experienced recurrence or metastasis, 53 (63.9%) received reoperation for their relapsed lesions. Patients who achieved microscopically negative margins (R0) at reoperation had significantly better PRS than those who did not (P < 0.007). Overall, patients with no recurrences had the best DSS, while relapsed patients receiving R0 reoperation had better DSS than those receiving either non-R0 reoperation or no reoperation at all. CONCLUSION Surgical margins prognostically influence survival in both patients undergoing primary surgery and those undergoing reoperation for relapse of extremity STS. In primary surgery, the chance of achieving adequate margin may reflect the underlying aggressiveness of tumors.

Abstract
Soft tissue sarcomas are very rare tumors. Available data are based on only a few prospective randomized trials. Most studies are retrospective, reviewing the results of single institutions. Furthermore, universally accepted treatment protocols for adult patients are lacking. Several prognostic factors have been identified, including grading, tumor size and development of metastatic disease; however, the relevance of other important aspects in the treatment of patients with soft tissue sarcomas remains unknown or subject to controversy. The main issues concern: which surgical margin width is safe from an oncological perspective? Does local recurrence influence survival? Can systemic chemotherapy improve prognosis? Is radiotherapy necessary in every case? Should it be applied pre-, post- or intraoperatively? What is the value of assessing the response after neoadjuvant therapy? These topics are examined in this review.

Abstract
Surgery and radiation therapy are the standard for local tumour control in the treatment of soft tissue sarcoma. Sarcoma recurrence within a previously irradiated area is one of the most problematic therapeutic challenges in soft tissue tumours. Any information on previous therapy needs to be available in detail. In case of recurrent sarcoma not amenable to surgical resection with wide and clear margins, a multimodality therapy needs to be applied. The armamentarium usually looks for a neoadjuvant downstaging of the sarcoma by radiotherapy, chemo-radiotherapy or isolated limb perfusion with all of those strategies bearing benefits, but also specific risks. The potential of repeated radiotherapy and the modality that can be used (intraoperative radiotherapy, brachytherapy) needs to be carefully evaluated. The pathologist saves these major problems in intraoperative frozen section histology or resection margins and thus needs to be aware of the type of cancer cells potentially present within the resection specimen. Plastic and reconstructive surgery to cover the area of re-resection with viable and well-v tissue is absolutely crucial to prevent lymphatic fistula. Thus, adequate treatment of those specific situations usually involves postoperative physiotherapy and a specific rehabilitation, which is extremely important.
