Neoadjuvant Therapies Do Not Reduce Epidermal Growth Factor Receptor (EGFR) Expression or EGFR-Targeted Fluorescence in a Murine Model of Soft-Tissue Sarcomas. Mol Imaging Biol 2024; 26:272-283. [PMID: 38151580 DOI: 10.1007/s11307-023-01884-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Revised: 11/01/2023] [Accepted: 12/01/2023] [Indexed: 12/29/2023]
Abstract
PURPOSE ABY-029, an epidermal growth factor receptor (EGFR)-targeted, synthetic Affibody peptide labeled with a near-infrared fluorophore, is under investigation for fluorescence-guided surgery of sarcomas. To date, studies using ABY-029 have occurred in tumors naïve to chemotherapy (CTx) and radiation therapy (RTx), although these neoadjuvant therapies are frequently used for sarcoma treatment in humans. The goal of this study was to evaluate the impact of CTx and RTx on tumor EGFR expression and ABY-029 fluorescence of human soft-tissue sarcoma xenografts in a murine model. PROCEDURES Immunodeficient mice (n = 98) were divided into five sarcoma xenograft groups and three treatment groups - CTx only, RTx only, and CTx followed by RTx, plus controls. Four hours post-injection of ABY-029, animals were sacrificed followed by immediate fluorescence imaging of ex vivo adipose, muscle, nerve, and tumor tissues. Histological hematoxylin and eosin staining confirmed tumor type, and immunohistochemistry staining determined EGFR, cluster of differentiation 31 (CD31), and smooth muscle actin (SMA) expression levels. Correlation analysis (Pearson's correlation coefficients, r) and linear regression (unstandardized coefficient estimates, B) were used to determine statistical relationships in molecular expression and tissue fluorescence between xenografts and treatment groups. RESULTS Neoadjuvant therapies had no broad impact on EGFR expression (|B|≤ 7.0, p ≥ 0.4) or on mean tissue fluorescence (any tissue type, (|B|≤ 2329.0, p ≥ 0.1). Mean tumor fluorescence was significantly related to EGFR expression (r = 0.26, p = 0.01), as expected. CONCLUSION Results suggest that ABY-029 as an EGFR-targeted, fluorescent probe is not negatively impacted by neoadjuvant soft-tissue sarcoma therapies, although validation in humans is required.

Abstract
Extremity and truncal soft tissue sarcomas are a heterogeneous group of rare cancers that arise from mesenchymal tissues. Hence, the adoption of tailored risk assessment and prognostication tools plays a crucial role in optimizing the decision-making for which of the many possible treatment strategies to select. Management of these tumors requires a multidisciplinary strategy, which has seen significant development in recent decades. Surgery has emerged as the primary treatment approach, with the main goal of achieving microscopic negative tumor margins. To reduce the likelihood of local recurrence, loco-regional treatments such as radiation therapy and isolated limb perfusion are often added to the treatment regimen in combination with surgery. This approach also enables surgeons to perform limb-sparing surgery, particularly in cases where a positive tumor margin is expected. Chemotherapy may also provide a further benefit in decreasing the probability of local recurrence or reducing distant metastasis in selected patients. Selecting the optimal treatment strategy for these rare tumors is best accomplished by an experienced multi-disciplinary team.

Improved Metastatic-Free Survival after Systematic Re-Excision Following Complete Macroscopic Unplanned Excision of Limb or Trunk Soft Tissue Sarcoma. Cancers (Basel) 2024; 16:1365. [PMID: 38611043 PMCID: PMC11010862 DOI: 10.3390/cancers16071365] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Revised: 03/22/2024] [Accepted: 03/27/2024] [Indexed: 04/14/2024] Open
Abstract
BACKGROUND Whether re-excision (RE) of a soft tissue sarcoma (STS) of limb or trunk should be systematized as adjuvant care and if it would improve metastatic free survival (MFS) are still debated. The impact of resection margins after unplanned macroscopically complete excision (UE) performed out of a NETSARC reference center or after second resection was further investigated. METHODS This large nationwide series used data from patients having experienced UE outside of a reference center from 2010 to 2019, collected in a French nationwide exhaustive prospective cohort NETSARC. Patient characteristics and survival distributions in patients reexcised (RE) or not (No-RE) are reported. Multivariate Cox proportional hazard model was conducted to adjust for classical prognosis factors. Subgroup analysis were performed to identify which patients may benefit from RE. RESULTS Out of 2371 patients with UE for STS performed outside NETSARC reference centers, 1692 patients were not reviewed by multidisciplinary board before treatment decision and had a second operation documented. Among them, 913 patients experienced re-excision, and 779 were not re-excised. Characteristics were significantly different regarding patient age, tumor site, size, depth, grade and histotype in patients re-excised (RE) or not (No-RE). In univariate analysis, final R0 margins are associated with a better MFS, patients with R1 margins documented at first surgery had a better MFS as compared to patients with first R0 resection. The study identified RE as an independent favorable factor for MFS (HR 0.7, 95% CI 0.53-0.93; p = 0.013). All subgroups except older patients (>70 years) and patients with large tumors (>10 cm) had superior MFS with RE. CONCLUSIONS RE might be considered in patients with STS of limb or trunk, with UE with macroscopic complete resection performed out of a reference center, and also in originally defined R0 margin resections, to improve LRFS and MFS. Systematic RE should not be advocated for patients older than 70 years, or with tumors greater than 10 cm.

The prognostic significance of surgical resection margins for local recurrence, distant metastasis, and overall survival in sarcoma. J Surg Oncol 2023; 128:1160-1170.

Abstract
BACKGROUND AND OBJECTIVES Surgical resection with microscopically negative margins constitutes one of the key elements of a curative therapeutic approach for localized sarcomas. However, the prognostic value of quantitative margin width remains controversial. We sought to determine the prognostic significance of margin status and margin width for local recurrence (LR), distant recurrence (DR), and overall survival. METHODS Retrospective analysis of 210 patients undergoing resection of localized sarcoma between 1997 and 2018 at a national sarcoma reference center. RESULTS Logistic regression did not reveal an effect of metric margin width as a prognostic factor for LR (odds ratio [OR] = 0.98, p = 0.574), DR (OR = 1, p = 0.908), or overall survival (hazard ratio = 0.98, 95% confidence interval = 0.73-1.20, p = 0.609). Subgroup analysis revealed no differences between complete first resections (R0) and re-resections (re-R0) following unplanned R1-resections for LR (p = 0.727) and overall survival (p = 0.125), but a significantly higher DR-rate in re-R0 cases (p = 0.022). CONCLUSIONS Achieving a negative margin is essential in sarcoma surgery, however, metric margin width was not associated with disease-specific outcomes. Re-resection of unplanned R1-resections should be performed to control for LR and overall survival rates. As re-R0 cases were at significantly higher risk of DR, these patients should be followed up closely in standardized surveillance protocols.

Abstract
Background and Objectives: Surgical management of local recurrence of soft tissue sarcomas (STS) is still challenging. In this article, we report on multiple flap reconstructions for multiple local recurrences of STS. Their feasibility will be validated by examining clinical cases. Materials and Methods: Patients who underwent multiple flap reconstructions for multiple local recurrences of STS between April 1997 and October 2021 were included in this retrospective study. Patient demographics, tumor characteristics, surgical characteristics, and postoperative complications were examined. Results: Twenty operations of eight patients were identified. The location of the defects was the back in two, the buttock in two, the groin in two, and the lower extremities in two. The average total number of wide resections was 4.0 and the average total number of flap reconstructions was 2.5. The average follow-up period was 109.4 months. The average size of the defect was 102.4 cm2 and the average flap size was 15.7 × 10.8 cm. The histological diagnoses were malignant fibrous histocytoma (MFH) in eight operations, osteosarcoma in two operations, myxoid liposarcoma in two operations, undifferentiated pleomorphic sarcoma (UPS) in six operations, and myxofibrosarcoma (MFS) in one operation. Of twelve subsequent operations, the resection of the previously transferred flap was performed in six operations (50%). The occurrence of take back, flap complications, and donor-site complications in the primary operation group was 25%, 25%, and 12.5%, respectively. The occurrence of take back, flap complications, and donor-site complications in the second and subsequent operation group was 0%, 0%, and 16.7%, respectively. Conclusions: Multiple operations including wide resections followed by flap reconstructions for multiple local recurrences are feasible. Reconstructive surgeons should choose the options of the flaps considering the future local recurrence for tumors with a high risk of recurrence.

Abstract
Almost half of retroperitoneal (RP) sarcomas are liposarcomas (LPS). The large majority of RP LPS are either well-differentiated LPS (WDLPS) or dedifferentiated LPS (DDLPS), these latter further classified according to grading in G2 and G3 DDLPS. Surgery is the only potentially curative treatment to achieve local control and possibly cure in primary localized disease. Over the last decade, a better delineation of the different histology-specific patterns of failure and the development of nomograms predictors of outcome has led to a better management of these rare tumors, with a special focus on non-surgical treatments. Available evidences - although far from exhaustive - show that radiation therapy might have a role, if any, as neoadjuvant treatment in locally aggressive histologies (i.e. WDLPS and G2 DDLPS), while it does not seem beneficial for histologies with a higher metastatic risk (i.e. G3 DDLPS and leiomyosarcoma). Neoadjuvant chemotherapy, instead, can be considered to reduce the risk of distant metastasis while waiting for the results of an ongoing RCT (STRASS-2) evaluating its effect in these tumors. However, given the rarity of these diseases and the subsequent lack of strong evidences to guide treatment, outcome improvement in these patients remains a challenge. Patients' referral to a sarcoma center where a dedicated specialized multidisciplinary team tailor optimal treatment on a case-by-case basis is crucial to ensure these patients the best outcome. Refining available nomograms - e.g including molecular variables - and identifying predictors of response/toxicity to chemotherapy and immunotherapy might be significantly helpful in tailoring treatments to the patient's characteristics. Also, new systemic agents are eagerly awaited for improving the management further.

Abstract
(1) Background: This study investigated the safety and efficiency of adriamycin and ifosfamide combined with anlotinib (AI/AN) as a neoadjuvant conversion therapy in uSTS. (2) Methods: Patients with uSTS were eligible to receive AI/An, including adriamycin (20 mg/m2/d) and ifosfamide (3 g/m2/d) for the first to the third day combined with anlotinib (12 mg/d) for 2 weeks on/1 week off, all of which combine to comprise one cycle. Surgery was recommended after four cycles of treatment. (3) Results: A total of 28 patients were enrolled from June 2018 to December 2020. The best tumor responses included eight patients with partial responses and 20 with a stable disease. Patients with synovial sarcoma and liposarcoma had a significant decrease in the number of tumors compared with fibrosarcoma (p = 0.012; p = 0.042). The overall response rate and disease control rate were 28.57% and 100%, respectively. In total, 24 patients received surgery, while the rates of limb salvage and R0 resection were 91.67% (n = 22/24) and 87.50% (n = 21/24), respectively. Until the last follow-up visit, the mean PFS and RFS were 21.70 and 23.97 months, respectively. During drug administration, 67.87% of patients had grade ≥3 AEs. No treatment-related death occurred. (4) Conclusions: AI/AN followed by surgery showed favorable efficiency and manageable safety in patients with uSTS. A randomized controlled study with a large cohort should be performed for further investigations.

Abstract
Background This French nationwide NETSARC exhaustive prospective cohort aims to explore the impact of systematic re-excision (RE) as adjuvant care on overall survival (OS), local recurrence free survival (LRFS), and local and distant control (RFS) in patients with soft tissue sarcoma (STS) with positive microscopic margins (R1) after initial resection performed outside of a reference center. Methods Eligible patients had experienced STS surgery outside a reference center from 2010 to 2017, and had R1 margins after initial surgery. Characteristics and treatment comparisons used chi-square for categorical variables and Kruskall-Wallis test for continuous data. Survival distributions were compared in patients reexcised (RE) or not (No-RE) using a log-rank test. A Cox proportional hazard model was used for subgroup analysis. Results A total of 1,284 patients had experienced initial STS surgery outside NETSARC with R1 margins, including 1,029 patients with second operation documented. Among the latter, 698 patients experienced re-excision, and 331 were not re-excised. Characteristics were significantly different regarding patient age, tumor site, tumor size, tumor depth, and histotype in the population of patients re-excised (RE) or not (No-RE). The study identified RE as an independent favorable factor for OS (HR 0.36, 95%CI 0.23–0.56, p<0.0001), for LRFS (HR 0.45, 95%CI 0.36–0.56, p<0.0001), and for RFS (HR 0.35, 95%CI 0.26–0.46, p<0.0001). Conclusion This large nationwide series shows that RE improved overall survival in patients with STS of extremities and trunk wall, with prior R1 resection performed outside of a reference center. RE as part of adjuvant care should be systematically considered.

Abstract
Background Soft-tissue sarcomas (STSs) are a rare heterogeneous group of tumors. Good functional results can be achieved with tumor excision in combination with suitable supplemental adjuvant therapies if needed. This study aimed to investigate the outcomes of wide resection of STS of the extremities. Methodology In this retrospective study, a total of 139 patients diagnosed with STS of the extremities by radiological and/or histopathological study/biopsy were included. All patients irrespective of metastasis were included. Results The mean age of the patients in our study was 43.5 ± 18.89 years. Overall, the mean tumor size was found to be 11.81 ± 6.218 cm. Malignant fibrous histiocytoma was the most common histology encountered (41%). Synovial sarcoma was the second most common histology encountered (14.38%). Recurrence was observed in 14 (10.1%) patients. The overall survival was 64.7% in our study. Conclusions The surgical margin achieved during the surgery is the most detrimental factor in local tumor control, and the overall survival of the patient after resection mainly depends on the stage of the tumor.

Abstract
BACKGROUND These clinical practice guidelines are intended to provide recommendations based on the best evidence obtained to date on key issues in clinical practice to improve the prognosis, diagnostic and therapeutic processes for patients with soft tissue tumors. METHODS The Guidelines Development Committee and Systematic Review Committee were composed of a multidisciplinary team of specialists who play an important role in soft tissue tumor care. Clinical questions (CQs) were determined by choosing key decision-making points based on Algorithms for the diagnosis and treatment of soft tissue tumors. The guidelines were developed according to the "Medical Information Network Distribution Service (Minds) Handbook for Clinical Practice Guideline Development 2014" and "Minds Manual for Clinical Practice Guideline Development 2017." Recommendation strength was rated on two levels and the strength of evidence was rated on four levels. The recommendations were decided based on agreement by 70% or more voters. RESULTS Twenty-two CQs were chosen by the Guidelines Development Committee. The Systematic Review Committee reviewed the evidence concerning each CQ, a clinical value judgment was added by experts, and the text of each recommendation was determined. CONCLUSION We established 22 CQs and recommendations for key decision-making points in the diagnosis and treatment of soft tissue tumors according to the Minds Clinical Practice Guideline development methods. We hope that these guidelines will assist the decision-making of all medical staff engaged in the treatment and diagnosis of soft tissue tumors, and eventually lead to improved soft tissue tumor care in the country.

Abstract
AIMS Current literature suggests that survival outcomes and local recurrence rates of primary soft-tissue sarcoma diagnosed in the very elderly age range, (over 90 years), are comparable with those in patients diagnosed under the age of 75 years. Our aim is to quantify these outcomes with a view to rationalizing management and follow-up for very elderly patients. METHODS Retrospective access to our prospectively maintained oncology database yielded a cohort of 48 patients across 23 years with a median follow-up of 12 months (0 to 78) and mean age at diagnosis of 92 years (90 to 99). Overall, 42 of 48 of 48 patients (87.5%) were managed surgically with either limb salvage or amputation. RESULTS A lower overall local recurrence rate (LRR) was seen with primary amputations compared with limb salvage (p > 0.050). The LRR was comparable between free (R0), microscopically (R1), and macroscopically positive (R2) resection margins in the limb salvage group. Amputation was also associated with longer survival times (p < 0.050). Overall median survival time was limited to 20 months (0 to 80). CONCLUSION Early and aggressive treatment with appropriate oncological surgery confers the lowest LRR and a survival advantage versus conservative treatment in this cohort of patients. With limited survival, follow-up can be rationalized on a patient-by-patient basis using alternative means, such as GP, local oncology, and/or patient-led follow-up.

Abstract
AIMS Urgent referral to a specialist centre for patients with a soft-tissue sarcoma (STS) has been recommended by the National Institute for Health and Care Excellence (NICE) in the UK since 2006. However, the impact of this recommendation on the prognosis for these patients remains unclear. We aimed to determine the impact of the NICE guidelines on the disease-specific survival (DSS) of patients with an STS. METHODS A total of 2,427 patients with an STS referred to a supraregional centre in the ten-year periods before (n = 1,386) and after (n = 1,041) the issue of the NICE guidelines were evaluated. RESULTS The mean size of the tumour was significantly smaller at the time of diagnosis (10.3 cm (SD 6.5) vs 9.1 cm (SD 6.2); p < 0.001) and the number of patients who had undergone an inadvertent excision significantly decreased (28% (n = 389) vs 20% (n = 204); p < 0.001) following the introduction of the NICE guidelines. The five-year DSS was 63% in the pre-NICE and 71% in post-NICE groups (p < 0.001). The improved survival was more significant for those with a high-grade tumour (pre-NICE, 48%; post-NICE, 68%; p < 0.001). In those with a high-grade tumour, the mean size of the tumour (11.6 cm (SD 6.2) vs 9.6 cm (SD 5.8); p < 0.001) and the number of patients with metastasis at the time of diagnosis (15% (n = 124 vs 10% (n = 80); p = 0.007) significantly decreased in the post-NICE group. CONCLUSION An improvement in survival was seen after the introduction of the NICE guidelines, especially in patients with a high-grade STS. More patients were referred at an earlier stage, indicating a clearer pathway after the issue of national policy for the management of STSs in the UK.

Abstract
BACKGROUND The impact of surgical margin status on the survival of patients with extremity soft tissue sarcoma (STS) remains to be clearly defined. The evidence regarding the impact of surgical margins on survival is limited by retrospective single-institution cohort studies. We conducted a systematic review and meta-analysis to examine the impact of surgical margin status on patient survival in extremity STS. METHODS A literature search in the PubMed, EMBASE, and Cochrane Controlled Trials Register electronic databases, and a manual search of reference lists of original studies was performed. The following text words and/or Medical Subject Heading terms were searched: (neoplasm) or/and (sarcoma) and/or (connective tissue) and/or (soft tissue) and/or (extremity) and/or (extremity) and/or (surgical margin). RESULTS Six selected studies that reported a total of 2917 cases of extremity STS were published between 1994 and 2013. All the eligible studies were observational cohort studies, and the sample size ranged from 95 to 1261 patients. A meta-analysis of 6 studies showed that a positive surgical margin predicted poor 5-year OS in a random-effects model (summary hazard ratio, 1.56; 95% confidence interval, 1.12-2.17). Moderate heterogeneity was observed among the studies (P < .075; heterogeneity, 45.6%). CONCLUSIONS This meta-analysis supports the hypothesis that adequate surgical margins are associated with improved survival in extremity STS.

Abstract
BACKGROUND Soft tissue sarcoma (STS) treatment is an interdisciplinary challenge. Along with radio(chemo)therapy, surgery plays the central role in STS treatment. Little is known about the impact of reconstructive surgery on STS, particularly whether reconstructive surgery enhances STS resection success with the usage of flaps. Here, we analyzed the 10-year experience at a university hospital's Comprehensive Cancer Center, focusing on the role of reconstructive surgery. METHODS We performed a retrospective analysis of STS-patients over 10 years. We investigated patient demographics, diagnosis, surgical management, tissue/function reconstruction, complication rates, resection status, local recurrence and survival. RESULTS Analysis of 290 patients showed an association between clear surgical margin (R0) resections and higher-grade sarcoma in patients with free flaps. Major complications were lower with primary wound closure than with flaps. Comparison of reconstruction techniques showed no significant differences in complication rates. Wound healing was impaired in STS recurrence. The local recurrence risk was over two times higher with primary wound closure than with flaps. CONCLUSION Defect reconstructions in STS are reliable and safe. Plastic surgeons should have a permanent place in interdisciplinary surgical STS treatment, with the full armamentarium of reconstruction methods.

Abstract
Tumor seeding after intra-abdominal and head and neck cancer surgery is a well-known entity. The risk of disseminating cancerous cells during surgery is also described for soft-tissue sarcoma of the extremities. Nonetheless, after reconstructive surgery using flaps, the risk of recurrence at the donor site is extremely rare. Up to this date, the literature describes only three cases, but none of them reported a translocated recurrence after a reconstruction with a propeller flap. Here, we report a case of high-grade pleomorphic sarcoma of the knee, which recurred at the proximal edge of a propeller flap 28 months after the first excision surgery. The reasons for such local recurrences are not clear and previous works have advocated different theories: direct contamination by tumor cells, physical manipulation of the tumor and creation of surgical wounds with tumor supportive properties. Although these particular cases of recurrence are exceedingly rare, certain precautionary meticulous surgical techniques and a thorough preoperative planning are pivotal to avoid the contamination of "clean" areas during the first excision surgery.

Abstract
Simple Summary In soft tissue sarcomas the width of surgical margins after resection determines the extent of surgery and the function after resection. But how far is really necessary? 305 patients with deep-seated, G2/3 soft tissue sarcomas of the extremity, the trunk wall, or the pelvis were reviewed. The 5-year local recurrence-free survival (LRFS) was 82%. Overall survival (OS) at 5 years was 66%. Positive (contaminated) margins worsened LRFS and OS. A margin of >10 mm did not improve LRFS and OS as compared to one of >5 mm. A resection margin of <1 mm showed a trend but not significantly better LRFS or OS compared to a contaminated margin. In conclusion the margin should at least be free of tumor, in sound tissue. A margin of >5 mm sound tissue seems to be sufficient. Resecting more tissue does not benefit the patient. Abstract Background: The significance of surgical margins after resection of soft tissue sarcomas in respect to local-recurrence-free survival and overall survival is evaluated. Methods: A total of 305 patients with deep-seated, G2/3 soft tissue sarcomas (STS) of the extremity, the trunk wall, or the pelvis were reviewed. The margin was defined according to the Fédération Nationale des Centres de Lutte Contre le Cancer (FNCLCC) classification system (R0-2), the Union Internationale Contre le Cancer (UICC) classification (R + 1 mm) for which a margin <1 mm is included into the R1 group, and in groups of <1 mm, 1–5 mm, >5 mm, or >10 mm. Results: Of these patients, 31 (10.2%) had a contaminated margin, 64 (21%) a margin of <1 mm, 123 (40.3%) a margin of 1–5 mm, 47 (15.4%) a margin of >5 mm, and 40 (13.1%) a margin of >10 mm. The 5-year local recurrence-free survival (LRFS) was 81.6%. Overall survival (OS) at 5 years was 65.9%. Positive margins worsened LRFS and OS. A margin of >10 mm did not improve LRFS and OS as compared to one of >5 mm. Conclusions: A resection margin of <1 mm showed a trend but not significantly better LRFS or OS compared to a contaminated margin. This finding supports use of the UICC classification. A margin of more than 10 mm did not improve LRFS or OS.

Abstract
INTRODUCTION Soft-tissue sarcoma (STS) denotes a group of rare and highly heterogeneous malignant tumors of mesenchymal origin. Accurate histological diagnosis is critical for selecting appropriate treatment. Complete tumor resection is the primary treatment for STS, and the efficacies of radiotherapy and chemotherapy have been tested in the adjuvant setting to improve oncological outcomes. Because most STS lesions arise in the extremities, preserving limb function and managing limb impairment after radical local treatment represent significant challenges. AREAS COVERED This article reviews the current front-line treatments for patients with extremity STS and discusses the multidisciplinary team-based efforts needed to improve oncological outcomes and survivorship. EXPERT OPINION Given the rarity, variety, and complexity of STS, a multidisciplinary approach involving experts in various disciplines is vital for improving outcomes in patients ranging from diagnosis to survivorship. A major challenge is building a sustainable system in each region permitting all patients with extremity STS to be treated at high-volume centers with multidisciplinary teams dedicated to this rare and complex disease.

Abstract
BACKGROUND Current practices for fluorescence-guided cancer surgery utilize a single fluorescent agent, but homogeneous distribution throughout the tumor is difficult to achieve. We hypothesize that administering a perfusion and a molecular-targeted agent at their optimal administration-to-imaging time will improve whole-tumor contrast. EXPERIMENTAL DESIGN Mice bearing subcutaneous xenograft human synovial sarcomas were administered indocyanine green (ICG) (3 mg/kg) or ABY-029 (48.7 μg/kg)-an epidermal growth factor receptor-targeted Affibody molecule-alone or in combination. Fluorescence contrast and signal distribution were compared between treatment groups. Two commercial fluorescence imaging systems were tested for simultaneous imaging of ICG and ABY-029. RESULTS ABY-029 has a moderate positive correlation with viable tumor (ρ = 0.2 ± 0.4), while ICG demonstrated a strong negative correlation (ρ = -0.6 ± 0.1). The contrast-to-variance ratio was highest in the ABY-029 +ICG (2.5 ± 0.8), compared to animals that received ABY-029 (2.3 ± 0.8) or ICG (2.0 ± 0.5) alone. Moreover, the combination of ABY-029 + ICG minimizes the correlation between viable tumor and fluorescence intensity (ρ = -0.1 ± 0.2) indicating the fluorescence signal distribution is more homogeneous throughout the tumor milieu. CONCLUSION Dual-agent imaging utilizing a single channel in a commercial fluorescence-guided imaging system tailored for IRDye 800CW is a promising method to increase tumor contrast in a clinical setting.

Abstract
BACKGROUND AND OBJECTIVES The propeller flap is a reliable option for reconstruction after soft tissue sarcoma resection. However, some parts of the resection margin may move away from its original position during flap rotation and thus can be excluded from the clinical target volume of adjuvant radiotherapy. This study aimed to evaluate local recurrence after soft tissue sarcoma resection with propeller flap or free flap reconstruction. METHODS Patients who underwent resection of soft tissue sarcoma followed by a free flap or propeller flap reconstruction and adjuvant radiotherapy at a single institution were retrospectively reviewed. RESULTS The 1- and 3-year local control rates were 94.6% and 88.6% in the free flap group vs 90.6% and 87.5% in the propeller flap group, without statistical significance. There were no statistically significant differences in 5-year local recurrence-free survival (88.6% vs 87.5%) and disease-free survival (82.5% vs 74.8%) between the groups. CONCLUSIONS Although there was no significant difference in local control and disease-free survival rates between propeller flap and free flap reconstruction after soft tissue sarcoma resection, a multidisciplinary approach is needed to obtain surgical information for determining the accurate clinical target volume of adjuvant radiotherapy and the area for meticulous follow-up postoperatively.

Abstract
Objective: To describe the types of intervention and determine patency and survival after arterial and venous reconstruction after surgical excision of sarcomas. Methods: Between November 2001 and July 2015, 42 patients with sarcomas and vascular involvement underwent surgical oncologic resection followed by arterial or venous reconstruction or preservation of the native vascular bundle. Univariate, multivariate, and Kaplan-Meier survival analyses were performed on abstracted data, which included demographics, risk factors, oncologic and vascular treatment modalities, postoperative complications, graft patency, and survival outcomes. Results: A total of 42 sarcomas required vascular assistance for oncologic removal. The majority of sarcomas were malignant fibrous histiocytoma (23.8%), and the most common anatomic location was the retroperitoneum (48%). A total of 12 revascularizations procedures were performed, including 5 arterial, 3 venous, and 2 concomitant arterial and venous. In 32 cases, a vascular surgeon was needed for vessel ligation, repair, or mobilization. The overall 2- and 5-year survival was 77.7% and 26.2%, respectively, with no significant survival difference between patients who underwent revascularization compared to those without revascularization. There was a 100% patency rate in all cases at last follow-up, regardless of the type of vascular reconstruction (median 18 months, range 1-29 months). On multivariate analysis, chronic obstructive pulmonary disease (COPD; P = .002) and positive surgical margins (P = .003) were associated with decreased survival. Most cases were performed in the last 5 years of the study (n = 27, 64.3%). Conclusions: Vascular reconstruction is feasible after surgical oncologic resection of sarcomas with good mid-term patency and limb preservation. Factors independently associated with mortality included COPD and positive surgical margins.

Abstract
BACKGROUND Quality measures for the surgical management soft tissue sarcoma of the extremity are limited. The purpose of this study was to define a textbook surgical outcome (TO) for soft tissue sarcoma of the extremities (STS-E) and to examine its associations with hospital volume and overall survival. METHODS All patients in the National Cancer Database undergoing resection of primary STS-E between 2004 and 2015 were identified. The primary outcome was a TO, defined as: hospital length of stay (LOS) <75th percentile, survival >90 days from the date of surgery, no readmission within 30 days of discharge, and negative surgical margins (R0 resection). RESULTS Overall, 7658 patients met criteria for inclusion; a TO was achieved in 4291 (56%) patients. Of patients who did not achieve TOs, 51.9% (n = 1748) had an extended LOS, and 47.3% (n = 1591) did not have negative margins. Older age, more medical comorbidities, and non-white or black race were independently associated with not receiving a TO (P = .034). With respect to tumor and treatment characteristics, larger tumor size, lower extremity location and higher grade were independently associated with not receiving a TO (P < .001). Hospital volume was not associated with a TO. TOs conferred a significant survival benefit (hazrds ratio = 0.71 [0.65-0.78], P < .001). A TO was associated with a 27.5% longer survival time (P < .001). CONCLUSIONS This study defined a TO in intermediate and high-grade STS-E and demonstrated that this outcome measure is associated with overall survival. Facility volume was not associated with a TO.

Abstract
Our retrospective study analysed the long-term results of a conservative limb-preserving surgical strategy in 51 patients with soft-tissue sarcoma of the hand from a single institution. We assessed survival and prognostic factors, including the surgical margins. No transradial amputations were performed. Microscopically free resection margins were obtained in 45 of the patients. The remaining six patients had microscopically incomplete resection. Forty-four surviving patients had a median follow-up of 6.5 years (range 12-307), and one patient had no follow-up beyond 3 months following surgery. Among those patients, 29 had more than 5 years of follow-up. Five-year local-recurrence-free survival was 65%, metastasis-free survival was 84%, and disease-specific survival was 91%. Tumour size was predictive of all outcome parameters, but positive resection margins adversely affected local recurrence only. Survival was similar to the survival after a more radical surgical approach reported in the literature. Level of evidence: IV.

Abstract
BACKGROUND AND OBJECTIVES The development of desmoid fibromatosis after tumor resection may mimic local recurrence. To our knowledge, this phenomenon has not been reported after extremity sarcoma resection. We report four cases of desmoid-type fibromatosis ("desmoid tumors") mimicking local recurrence after extremity sarcoma resection. METHODS We retrospectively reviewed the records of patients treated for extremity sarcoma by our orthopedic oncology service from 2014 to 2019 and identified four patients with biopsy-proven desmoid tumors. We extracted clinical, pathologic, radiographic, and operative data for the primary neoplasms and desmoid tumors. RESULTS Four patients with postresection surveillance magnetic resonance imaging suspicious for local recurrence underwent further analysis showing desmoid tumors. Patients underwent image-guided needle biopsy, with specimens demonstrating fibromatosis-type histologic characteristics. Two cases were β-catenin positive. Desmoid tumors were managed with observation. No patient had experienced local or distant recurrence of the primary tumor at a mean follow-up of 30 months after resection (range, 23-34 months); none underwent surgery for symptoms of desmoid tumors. CONCLUSIONS Desmoid tumors should be considered part of the differential diagnosis when assessing patients with radiographic concern for postresection local recurrence of extremity bone and soft-tissue sarcoma. An image-guided needle biopsy can inform diagnosis and management.

Abstract
Wound closure after wide, local excision of an appendicular soft-tissue sarcoma (STS) can be challenging. This study evaluates the value of magnetic resonance imaging (MRI)-based tumour parameters in planning wound closure. A total of 71 patients with a primary limb-based STS, excluding vascular or osseous involvement, excluding the shoulder or hand and hip or foot were included. Axial MRI images were used to measure the circumferences and cross-sectional areas of the limb, bone, and tumour. The tumour diameter, length, and depth at the level of maximal tumour dimension were measured to identify the tumour's relative contribution to the planning of optimal wound closure management through primary closure (PC) or reconstructive surgery (RS). Eighteen patients required planned wound RS. Wound complications occurred in 14% overall. Tumours, which were closed by PC, were of significantly greater depth, shorter radial diameter, and shorter tumour circumference relative to those closed by RS. On multivariate analysis, tumour depth was the greatest contributory factor in predicting type of wound closure. A quantitative analysis of MRI-based tumour parameters demonstrates tumour depth as the most predictive factor in planning for the type of wound closure and may prove beneficial in providing greater insight into planned wound management of sarcoma resection.

Abstract
BACKGROUND Soft tissue sarcomas (STS) are a rare and heterogeneous group of malignant tumors that arise from the mesenchymal tissue. STS can form anywhere in the human body, with the extremities being preferred sites of predilection. TREATMENT A fundamental pillar of treatment is the surgical resection of soft tissue sarcomas. The goal is always an R0 resection with a safety margin. There is no consensus in the literature about the desired tumor-free resection margin. The decisive factors for these resection margins are histopathology, presence of anatomical barriers (capsule, tendon, fascia, cartilage, periosteum) and possibilities of (neo-) adjuvant therapy. DISCUSSION References in the literature support the role of resection margins as a predictor of local recurrence. Regarding the role of resection margins in overall survival, available data is divergent. There are known prognostic factors that influence overall survival, such as histological subtype, tumor size, tumor grading, and presence of metastases. So far, several studies have attempted to quantify the margins of resection, but no consensus has been reached, and debates are ongoing. When analyzing all the results of the data in the literature, it seems appropriate to aim for a negative resection margin >1 mm including an anatomical border structure, if possible.

Abstract
OPINION STATEMENT The proper diagnosis and treatment planning for subcutaneous soft tissue sarcoma is very important. Soft tissue tumors can occur anywhere in the body, but if they occur subcutaneously, patients can easily notice a subcutaneous soft tissue mass. Therefore, it is possible to determine through recording, the growth speed of the mass, which is often difficult to obtain with deep-situated soft tissue masses. Palpation can also provide information about the firmness and mobility of the mass. Thus, history taking and physical examinations are informative for subcutaneous soft tissue tumors, compared to tumors that occur deeply. Because subcutaneous soft tissue tumors are easily recognized, they are often resected, without sufficient imaging analyses or thorough treatment planning. An operation performed based on such an inadequate preoperative plan is called a "whoops surgery." In the case of "whoops surgeries," subsequent radical surgery is required to remove additional areas, including hematomas that result from the initial surgery, that require a wider range of resection and soft tissue reconstruction. Therefore, as with deep-seated soft tissue tumors, it is important to conduct careful imaging examinations and make appropriate preoperative plans for subcutaneous soft tissue tumors. Subcutaneous soft tissue sarcomas often show an invasive pattern, and such tumors require a more careful assessment to prevent local recurrence after surgery. During surgery, it is necessary to remove the entire infiltration area along the fascia. Sometimes, an adequately wide excision is necessary, which is considered the minimum necessary procedure to eradicate the lesion. As noted above, clinicians who see patients with subcutaneous soft tissue tumors are encouraged to have sufficient knowledge and experience regarding the diagnosis and treatment. This article is intended for all doctors who deal with subcutaneous soft tissue tumors and focuses on essential points regarding their diagnosis and management.

Abstract
BACKGROUND AND OBJECTIVES Fluorescence-guided surgery using epidermal growth factor receptor (EGFR) targeting has been performed successfully in clinical trials using a variety of fluorescent agents. We investigate ABY-029 (anti-EGFR Affibody® molecule labeled with IRDye 800CW) compared with a small-molecule perfusion agent, IRDye 700DX carboxylate, in a panel of soft-tissue sarcomas with varying levels of EGFR expression and vascularization. METHODS Five xenograft soft-tissue sarcoma cell lines were implanted into immunosuppressed mice. ABY-029 and IRDye 700DX were each administered at 4.98 μM. Fluorescence from in vivo and ex vivo (fresh and formalin-fixed) fixed tissues were compared. The performance of three fluorescence imaging systems was assessed for ex vivo tissues. RESULTS ABY-029 is retained longer within tumor tissue and achieves higher tumor-to-background ratios both in vivo and ex vivo than IRDye 700DX. ABY-029 fluorescence is less susceptible to formalin fixation than IRDye 700DX, but both agents have disproportional signal loss in a variety of tissues. The Pearl Impulse provides the highest contrast-to-noise ratio, but all systems have individual advantages. CONCLUSIONS ABY-029 demonstrates promise to assist in wide local excision of soft-tissue sarcomas. Further clinical evaluation of in situ or freshly excised ex vivo tissues using fluorescence imaging systems is warranted.

Abstract
Objectives This study aims to assess the impact of surgical margin and malignancy grade on overall survival (OS) and local recurrence free rate (LRFR) for soft tissue sarcomas (STS) of the thoracic wall. Methods This retrospective cohort study identified 88 patients, diagnosed and treated surgically for a nonmetastatic STS located in the thoracic wall between 1995 and 2013, using the population based and validated Aarhus Sarcoma Registry and Danish Sarcoma Registry. The Kaplan-Meier method was used to estimate OS and LRFR. Multivariate Cox analyses were used to determine prognostic factors for OS and LRFR. Results The 5-year OS was 55% (95% confidence interval (CI): 0.44-0.65) and 5-year LRFR was 77% (95% CI: 0.67-0.85). High malignancy grade and intralesional/marginal resection were identified as negative predictors for OS. High grade was the only prognostic factor associated with a lower LRFR. Conclusions In this large, single institution, study tumor grade was the key predictor for OS and LRFR. Surgical margin only statistically significantly influenced mortality, not local recurrence.

Abstract
Many tumors for which fluorescence guided surgery (FGS) has been developed are surface tumors, where direct visualization by the surgeon is straightforward. On the other hand, cancers such as soft-tissue sarcomas, are present at a subsurface level. Resection of these sub-surface tumors is performed using 'wide local excision' where a single, complete mass is removed with an intact zone of normal tissue (~ 1 cm 'margin'). We used a phantom model for sarcoma with near infrared fluorophore IRDye800 CW that defined different tissue properties. We compare the detection sensitivity of two commercially available near infrared (NIR) surgical imaging systems, Solaris (Perkin Elmer) and SPY PHI (Novadaq) using the phantom models of sarcoma. We also determine targeted fluorescence signal on both systems for blinded surgical phantom dissection by a surgeon. The fluorescence intensities are higher for Solaris than for SPY-PHI. On average, the fluorescence increased with an increase in intralipid concentration and decreased with an increase in blood concentration. The depth of imaging was higher for Solaris than for SPY PHI. Using the target values, the surgeon successfully dissected all phantoms using Solaris. Using fat phantoms for SPY PHI, the surgeon cut through four out of the total. Further improvement in FGS will improve cancer recurrence and morbidity.

Abstract
Purpose Soft tissue sarcoma (STS) is a rare and heterogeneous cancer with over 50 known subtypes. It is difficult to understand the role of adjuvant treatment in STS. We aimed to determine the benefits of adjuvant treatment for a rare STS subset: non-extremity STS with moderate chemosensitivity. Materials and Methods We reviewed medical records from Pusan National University Hospital and Kosin University Gospel Hospital, which had detailed pathological reports on patients diagnosed between 2006 and 2016. The most important inclusion criterion was resection with curative intent. We grouped STS by chemosensitivity based on reported data and analyzed non-extremity STS with moderate chemosensitivity. Results We investigated 142 patients with 20 pathological subtypes of STS. Eighty-six patients had extremity STS and 56 had non-extremity STS. Thirty-eight of 56 patients were categorized as having moderate chemosensitivity. Seventeen of 38 patients (44.7%) received adjuvant radiotherapy and 14 (36.8%) received adjuvant chemotherapy. A log-rank test showed longer disease-free survival (DFS) in the adjuvant radiotherapy group than in the group treated without adjuvant radiotherapy (not reached vs. 1.468 years, p = 0.037). Multivariate Cox proportional hazard analysis, with covariates including age, stage, resection margin, adjuvant chemotherapy, and adjuvant radiotherapy, revealed that adjuvant radiotherapy was associated with longer DFS (odds ratio = 0.369, p = 0.045). Overall survival was not correlated with adjuvant radiotherapy. Conclusion Adjuvant radiotherapy may be associated with longer DFS in patients with non-extremity STS with moderate chemosensitivity.

Abstract
Sarcomas are rare mesenchymal bone and soft tissue tumors of the musculoskeletal system. In the past, the primary treatment modality was amputation of the involved limb and the 5-year survival was very low for high-grade tumors. During the last three decades, limb salvage has become the rule rather than the exception and the use of neoadjuvant and adjuvant therapies (radiation and chemotherapy) has dramatically increased disease-free survival. Reconstruction of large bone and soft tissue defects, though, still remains a significant challenge in sarcoma patients. In particular, vascularized tissue transfer has proved extremely helpful in dealing with complex bone and soft tissue or functional defects that are frequently encountered as a result of the tumor or as a complication of surgery and adjuvant therapies. The principles, indications and results of microsurgical reconstruction differ from trauma patients and are directly related not only to the underlying disease process, but also to the local and systemic therapeutic modalities applied to the individual patient. Although plastic reconstruction in the oncological patients is not free of complications, usually these complications are manageable and do not jeopardize oncological outcome. The overall treatment strategy should be tailored to the patient's and sarcoma profile.

Abstract
Soft-tissue sarcomas pose diagnostic and therapeutic challenges to physicians, owing to the large number of subtypes, aggressive tumor biology, lack of consensus on management, and controversy surrounding interval and duration of surveillance scans. Advances in multidisciplinary management have improved the care of sarcoma patients, but controversy remains regarding strategies for surveillance following definitive local control. This review provides an updated, comprehensive overview of the current understanding of the risk of local recurrence of soft-tissue sarcoma, by examining the literature based on features such as histological type and grade, tumor size, and resection margin status, with the aim of helping clinicians, surgeons, and radiologists to develop a tailored approach to local imaging surveillance.

Abstract
BACKGROUND Somatic leiomyosarcoma (LMS) is an aggressive soft tissue sarcoma entity with a high metastatic potential. The purpose of this study was to identify prognostic indicators of survival in patients with somatic LMS of the soft tissues. METHODS We retrospectively assessed the relationship between local recurrence-free survival (LRFS), disease-specific survival (DSS), overall survival (OS) and potential prognostic factors in 164 patients who were suitable for surgical treatment in curative intent. Patients with soft tissue LMS of the extremities, the truncal wall and the head and neck area were included. The median follow-up time was 4.9 years. RESULTS In the entire cohort, the 5-year estimate of the DSS, OS and LRFS rate were 74.5% (95% confidence interval [CI] 65.0-81.8), 70.6% (95% CI: 60.9-78.3) and 63.4% (95% CI 53.4-71.9), respectively. Thirty-eight patients (23.2%) developed distant metastases with a median survival time of 1.5 years after diagnosis of metastasis. Surgical margins attained at the initial oncologic resection and eventual re-excisions did not influence DSS, OS and LRFS significantly. Within the R0 subgroup, close and wide negative margins led to similar outcomes. High histologic grade (P < 0.001), size >5 cm (P = 0.002) and subfascial localisation (P = 0.002) were associated with significantly diminished DSS in univariate analysis. In multivariate analysis, only histologic grade was found to be an independent prognostic factor of DSS. CONCLUSIONS The data from this study could not determine a prognostic significance of surgical margins suggesting that tumour characteristics other than margin status are important. Tumour biology reflected by the histologic grade dictates the final outcome.

Abstract
The excision of tumors by wide local excision is challenging because the mass must be removed entirely without ever viewing it directly. Positive margin rates in sarcoma resection remain in the range of 20% to 35% and are associated with increased recurrence and decreased survival. Fluorescence-guided surgery (FGS) may improve surgical accuracy and has been utilized in other surgical specialties. ABY-029, an anti-epidermal growth factor receptor Affibody molecule covalently bound to the near-infrared fluorophore IRDye 800CW, is an excellent candidate for future FGS applications in sarcoma resection; however, conventional methods with direct surface tumor visualization are not immediately applicable. A novel technique involving imaging through a margin of normal tissue is needed. We review the past and present applications of FGS and present a novel concept of indirect FGS for visualizing tumor through a margin of normal tissue and aiding in excising the entire lesion as a single, complete mass with tumor-free margins.

Abstract
Soft tissue sarcomas (STS) are a heterogeneous group of rare mesenchymal tumors that account for approximately 1% of all adult malignancies. They can arise throughout the body due to their mesenchymal origin, although 60% of all STS occur in the extremities. Locally advanced STS can lead to significant functional morbidity and tend to local recurrences despite surgical resection. About 30% of all STS patients develop distant metastases with a median overall survival of less than 15 months. The treatment of choice in patients with localized disease is still surgical resection with negative margins. However, there has been a paradigm shift in the last few decades. Large retrospective analyses could not establish a strong association between radical resections and improved local control or survival. Previous radical concepts in STS surgery have been gradually replaced by more moderate approaches with function- and limb-sparing resections combined with radiotherapy. Here, the margin status appears to be of prognostic significance. However, several large retrospective analyses have presented inconsistent results, questioning the independent prognostic impact of surgical margins. This article reviews the literature critically, focusing on the changing role of surgical margins in STS surgery.

Abstract
Wide local excision (WLE) of tumors with negative margins remains a challenge because surgeons cannot directly visualize the mass. Fluorescence-guided surgery (FGS) may improve surgical accuracy; however, conventional methods with direct surface tumor visualization are not immediately applicable, and properties of tissues surrounding the cancer must be considered. We developed a phantom model for sarcoma resection with the near-infrared fluorophore IRDye 800CW and used it to iteratively define the properties of connective tissues that typically surround sarcoma tumors. We then tested the ability of a blinded surgeon to resect fluorescent tumor-simulating inclusions with ∼1-cm margins using predetermined target fluorescence intensities and a Solaris open-air fluorescence imaging system. In connective tissue-simulating phantoms, fluorescence intensity decreased with increasing blood concentration and increased with increasing intralipid concentrations. Fluorescent inclusions could be resolved at ≥1-cm depth in all inclusion concentrations and sizes tested. When inclusion depth was held constant, fluorescence intensity decreased with decreasing volume. Using targeted fluorescence intensities, a blinded surgeon was able to successfully excise inclusions with ∼1-cm margins from fat- and muscle-simulating phantoms with inclusion-to-background contrast ratios as low as 2∶1. Indirect, subsurface FGS is a promising tool for surgical resection of cancers requiring WLE.

Abstract
PURPOSE To evaluate the efficacy and tolerance of adjuvant concurrent chemoradiation (CCRT) as treatment of grade 2 and 3 (G2-3) localized extremity soft tissue sarcomas (STS) by comparing CCRT with standard adjuvant radiation therapy (RT). PATIENTS AND METHODS This monocentric retrospective study included non-pediatric patients (>16years) treated by adjuvant RT with or without chemotherapy (CT) after conservative resection of non-recurrent G2-3 extremity STS. RESULTS A total of 80 patients were treated between 1990 and 2012: 51 by RT and 29 by CCRT. Of the 29 CCRT patients, 25 received doxorubicin monotherapy (75mg/m2/3weeks). The CCRT group contained a greater proportion of grade 3 extremity STS (p<0.001). Median follow up was 68months (9-284). Multivariate analysis revealed greater local control in the CCRT group (1 local recurrence vs 8 in the RT group; HR=0.082, 95% CI 0.011-0.321) and incomplete resection as the major risk factor of local recurrence (HR=25.2, 95% CI 4.767-133.226). The two groups exhibited no differences in distant failure-free survival (HR=1.469, 95% CI 0.668-3.228), disease-free survival (HR=1.096, 95% CI 0.519-2.315) or overall survival (HR=1.378, 95% CI 0.498-3.814). Grade 3 was an adverse prognostic factor for overall survival (HR=3.11, 95% CI 1.04-9.32). Our analyses also revealed that CCRT tended to increase the risk of both grade ≥3 acute dermatitis (14 events vs 6 in the RT group; OR=6.99, 95% CI 2.28-21.47) and grade ≥2 late toxicity (6 events vs 3 in the RT group; p=0.0572). CONCLUSION CCRT could improve local control as part of a limb-preservation strategy. However, with a limited number of patients, CCRT showed no improvement in either distant control or survival and increased toxicity.

Abstract
BACKGROUND Soft tissue sarcomas (STS) arising in the extremities pose a therapeutic challenge due to concerns of functional morbidity. Resections with negative margins are the mainstay of therapy, but the prognostic significance of surgical margins remains controversial. The purpose of this study was to determine the prognostic impact of surgical margins and clear margin widths in patients with STS of the extremities. MATERIALS AND METHODS We assessed the relationship between local recurrence-free (LRFS), disease-specific (DSS), and metastasis-free survival (MFS) and potential prognostic factors retrospectively in a consecutive series of 643 patients treated at our institution between 1996 and 2016. Potential prognostic factors were assessed using univariate and multivariate analyses. RESULTS The median follow-up time after primary diagnosis was 5.4 years (95% confidence interval [CI]: 4.8-6.0). The five-year estimates of the DSS, LRFS, and MFS rates in the entire cohort were 85.3% (95% CI: 81.6-88.3), 65.3% (95% CI: 60.8-69.5) and 78.0% (95% CI: 74.1-81.4), respectively. Histological grade and the quality of surgical margins were independent prognostic factors of all three survival endpoints (LRFS, DSS, MFS) in multivariate analyses. Within the R0 subgroup, univariate and multivariate analyses of categorized (≤1 mm vs. 1-5 mm vs. >5 mm) and non-categorized margin widths revealed that close and wide negative margins led to similar outcomes. Adjuvant radiation improved local control independently, but not DSS and MFS. CONCLUSION Microscopically negative margins were associated with better LRFS, DSS, and MFS regardless of whether adjuvant radiation was applied. Here, surgical margins can be close as long as the resected tumor has no ink on it. IMPLICATIONS FOR PRACTICE In the present retrospective analysis of 643 patients with primary soft issue sarcomas of the extremities, surgical margins could be identified as independent predictors of local recurrence-free, disease-specific, and metastasis-free survival. Given the diminished outcome of patients left with positive margins, surgical efforts should aim to achieve microscopically negative margins whenever feasible. It is noteworthy that only the quality of surgical margins, but not the negative margin width attained, had an influence on the prognosis. Our findings suggest that surgical margins can be close as long as the resected tumor has no ink on it.

Abstract
BACKGROUND/OBJECTIVES Evaluation of our surveillance program for soft tissue sarcomas (STS) and borderline tumors (BT) for identification of local recurrence and lung metastases the first 2 years postoperatively. METHODS We retrospectively assessed the medical files of all patients (n = 232) with STS and BT of the extremities and trunk wall who underwent surgery from 2010 to 2013. Two-hundred-and-thirty-two patients were included in the local recurrence study and 116 patients in the lung metastasis study. We extracted information on how local recurrence and lung metastases were detected. Kaplan-Meier survival analysis and 2 × 2-contingency table with Chi-square test were used. Local recurrence and lung metastases were analyzed separately. RESULTS Twenty-five of 232 patients experienced local recurrence and 19 of 116 patients experienced lung metastases. Compared to clinical examination, local imaging led to a larger amount of local recurrence suspicions (37/560 vs. 8/706). Suspicions occurring on local imaging were more accurate than on clinical examination (17/37 vs. 0/8 affirmed). Local imaging identified a larger amount of local recurrence than clinical examination (17/560 vs. 0/706). Thirty-three patients suspected local recurrence themselves, 8 were affirmed. Compared to x-ray, computerized tomography (CT) led to a larger amount of lung metastasis suspicions (22/284 vs. 6/276). Suspicions occurring on CT seemed more accurate than on x-ray (15/22 vs. 2/6 affirmed). CT found a larger amount of lung metastases than x-ray (15/284 vs. 2/276). Three patients suspected lung metastases themselves, 1 was affirmed. CONCLUSION Bi-annual local imaging and CT the first 2 years after surgery of STS detect local recurrence and lung metastases better than clinical examination and x-ray. Clinical examination and x-ray between these examinations is unnecessary. Patients' own suspicion of local recurrence and lung metastases is still important.

Abstract
Soft tissue sarcomas are a rare entity. While surgery is established as the mainstay of treatment, the exact role and sequencing of adjuvant therapy is not well defined. Literature on Indian patients with soft tissue sarcoma with respect to clinical profile and prognostic factors is scarce. We retrospectively analysed the data of 112 patients operated for soft tissue sarcoma of extremity or trunk (excluding retroperitoneal and mediastinal sarcomas, round cell histology) at our institute from 1 January 2009 to 31 December 2013. Around half the patients were less than 50 years of age and around a third had size more than 10 cm. Oncological outcome was correlated with various demographic, tumour-related and treatment-related factors using SPSS 22. Overall survival at 5 years was 73.2 % and event-free survival at 5 years was 42.2 %. At final follow-up (mean of 44.85 ± 4.64 months), local recurrence was seen in 31.9 % and distant metastasis was seen in 30.1 % of the patients. Using both univariate and multivariate analysis, younger age (<50 years), larger size (>10 cm, but not >5 cm) and pathologically positive lymph nodes were the only factors found significantly affecting overall survival. The clinical profile and prognosis of Indian patients with soft tissue sarcoma were found to be different from that reported in Western literature. The impact of established prognostic indicators for soft tissue sarcoma also differed in Indian patients, which may have both prognostic and therapeutic implications.

Abstract
Soft tissue sarcomas are uncommon tumours of mesenchymal origin, most commonly arising in the extremities. Treatment includes surgical resection in combination with radiotherapy. Resection margins are of paramount importance in surgical treatment of soft tissue sarcomas but unambiguous guidelines for ideal margins of resection are still missing as is an uniform guideline on the use of radiotherapy. The present paper reviews the literature on soft tissue sarcomas of the extremities regarding the required resection margins, the impact of new radiotherapy techniques and the timing of radiotherapy, more particularly if it should be administered before or after surgical resection. This review was started by searching guidelines in different databases (National Guideline Clearinghouse, EBMPracticeNet, TRIP database, NCCN guidelines,…). After refinement of the query, more specific articles were found using MEDLINE, PubMed, Web of Science and Google Scholar. Used keywords include “soft tissue sarcoma”; “extremities OR limbs”; “radiotherapy”, “surgery”, “margins”, “local recurrence” and “overall survival”. Finally, the articles were selected based on the accessibility of the full text, use of the English language and relevance based on title and abstract. Literature demonstrates positive resection margins to be an important adverse prognostic factor for local recurrence of soft tissue sarcomas of the extremities. Still, no consensus is reached on the definition of what a good margin might be. The evolution of new radiation techniques, especially Intensity Modulated Radiotherapy, resulted in a s healthy surrounding tissues. However, the timing of radiotherapy treatment remains controversial as both preoperative and postoperative radiotherapy are characterised by several advantages and disadvantages.

Abstract
Soft tissue sarcomas comprise tumors originating from mesenchymal or connective tissue. Histologic grade is integral to prognosis. Because sarcoma management is multimodal, histologic subtype should inform optimum treatment. Appropriate biopsy and communication between surgeon and pathologist can help ensure a correct diagnosis. Treatment often involves surgical excision with wide margins and adjuvant radiotherapy. There is no consensus on what constitutes an adequate margin for histologic subtypes. An appreciation of how histology corresponds with tumor biology and surgical anatomic constraints is needed for management of this disease. Even with the surgical goal of wide resection being obtained, many patients do not outlive their disease.

The Width of the Surgical Margin Does Not Influence Outcomes in Extremity and Truncal Soft Tissue Sarcoma Treated With Radiotherapy. Oncologist 2016; 21:1269-1276. [PMID: 27440063 DOI: 10.1634/theoncologist.2015-0534] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2015] [Accepted: 05/13/2016] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND AND OBJECTIVES It is unclear whether the quantitative width of the surgical margin influences outcomes in patients with extremity and truncal soft tissue sarcoma (STS) treated with radiotherapy (RT). METHODS We performed a retrospective review of 382 patients with localized extremity or truncal STS who underwent limb-sparing surgery and RT from 1983 to 2010, and we analyzed the significance of resection margin status and quantitative margin width on outcomes. RESULTS Surgical margins were positive in 68 (18%) patients and negative in 314 (82%) patients. For those patients with a reported quantitative margin width (n = 235), the width of the negative margin was ≤1 mm (n = 128), >1 mm and ≤5 mm (n = 79), and >5 mm (n = 28). At a median follow-up of 82 months, the local recurrence rates were 5.4% and 11.8% for margin-negative and margin-positive patients, respectively. There were no differences in the rates of local or distant recurrence nor of any survival outcome based on the quantitative width of the surgical margin, provided that it was negative. CONCLUSIONS In patients undergoing RT and limb-sparing surgery for STS, achieving a negative margin is essential for optimizing both local control and survival. However, the absolute quantitative width of the negative margin does not significantly influence outcome, and so attempts at wide margins of resection appear to be unnecessary. Importantly, the conclusions drawn from this study must not be applied to those patients undergoing surgery alone as the local treatment of their STS, in which case wider margins of resection may be necessary. IMPLICATIONS FOR PRACTICE In patients undergoing radiation therapy and limb-sparing surgery for soft tissue sarcoma, the quantitative width of the negative margin does not influence outcome, and so attempts at wide margins of resection appear to be unnecessary, especially when such attempts compromise the functional outcome. Importantly, the conclusions drawn from this study must not be applied to those patients undergoing surgery alone as the local treatment of their soft tissue sarcoma, in which case wider margins of resection may be necessary.

Abstract
BACKGROUND Patients with soft tissue sarcoma (STS) being treated following the standardized guidelines can still not be guaranteed to remain free from local recurrence (LR). A complete tumour resection has been accepted as a major prognostic factor for LR. This retrospective study was designed to analyse the influence of two different classifications of resection margins (R-classification and UICC-classification) on LR in STS patients. MATERIALS AND METHODS Of 411 patients treated at our institution for STS, 265 were eligible for statistical analysis. Kaplan-Meier curves and Cox regression models were used to assess the impact of an R0 resection according to the R-classification (resection margin clear but allowing <1 mm) and according to the UICC-classification (minimal resection margin ≥1 mm) on LR. RESULTS Survival curves showed a lower LR rate for R0 resections in the UICC-classification, namely 1.3%, 12% and 12% as compared to 2.1%, 9.5% and 16.5% for the R-classification. In multivariate analysis calculated separately for each classification, R1 resection as defined by the R-classification (HR: 11.214; 95%CI: 2.394-52.517; p = 0.002) as well as by UICC-classification (HR: 15.634; 95%CI: 2.493-98.029; p = 0.003) remained significant. CONCLUSION In our study, margin status according to both classifications represents an independent prognostic factor for LR in patients with STS following curative surgery. Local control rates were superior after a minimal resection margin of 1 mm (R0 by UICC-classification) compared to R0 resections after the R-classification.

Abstract
Introduction Solid malignancies at the foot and ankle region are rare and include mainly soft-tissue sarcomas, bone sarcomas, and skin malignancies. Complete surgical resection with clear margins still remains the mainstay of therapy in these malignancies. However, attainment of negative surgical margins in patients with locally advanced tumors of the foot and ankle region may require extensive surgery and could result in loss of extremity function. In these circumstances, plastic surgical techniques can frequently reduce functional impairment and cover soft-tissue defects, particularly in cases of large tumor size or localization adjacent to critical anatomic structures, thereby improving the quality of life for these patients. The aim of this article is to illustrate the various treatment options of plastic surgery in the multimodal therapy of patients with malignant tumors of the foot and ankle region. Materials and methods This article is based on the review of the current literature and the evaluation of the author’s own patient database. Results The local treatment of malignant extremity tumors has undergone major changes over the last few decades. Primary amputations have been increasingly replaced by limb-sparing techniques, preserving extremity function as much as possible. Although defect coverage at the foot and ankle region is demanding due to complex anatomical features and functional requirements, several plastic surgical treatment options can be implemented in the curative treatment of patients with malignant solid tumors in this area. Soft-tissue defects after tumor resection can be covered by a variety of local flaps. If local flaps are not applicable, free flap transfers, such as the anterolateral thigh flap, parascapular flap, or latissimus dorsi flap, can be utilized to cover nearly all kinds of defects in the foot and ankle region. Conclusion Soft-tissue reconstruction in the foot and ankle region is a vital component of limb-sparing surgery. It enables complete resection of locally advanced tumors and subsequent adjuvant radiotherapy. Modern plastic surgical techniques should, therefore, be integrated in the multimodal treatment concept of malignancies in the foot and ankle region.

Abstract
Post-treatment imaging of musculoskeletal sarcoma remains challenging, but newer imaging techniques are improving our ability to recognize both local and distant recurrence and accurately distinguish local recurrence from post-treatment change. We review recent advances in dynamic contrast-enhanced magnetic resonance imaging, diffusion-weighted magnetic resonance imaging with apparent diffusion coefficient mapping and positron emission tomography/computed tomography in the post-treatment follow-up of musculoskeletal sarcoma. We also describe our multidisciplinary sarcoma team approach to patient care and the essential role of the radiologist in the clinical follow-up scheme.
