Abstract
Equine neoplasia poses challenges in surgical management owing to their diverse locations and potential for aggressive behavior. Surgical interventions aim for complete excision while minimizing cosmetic and functional impairments. Techniques such as laser ablation and electrochemotherapy offer minimally invasive options for accessible tumors. For deeper or larger masses, surgical excision with adequate margins remains the gold standard. Preoperative biopsy and imaging guides surgical planning, ensuring complete tumor removal while preserving vital structures. Close adherence to a strict surgical protocol to prevent seeding of tumor cells, and, where possible, appropriate skin reconstruction techniques will improve cosmesis and outcome.

Abstract
INTRODUCTION Soft tissue sarcomas are a group of malignancies that commonly occur in the extremities. As deep lesions may exist within the confines of the muscular fascia, we postulate that local recurrence rates are higher for superficial soft tissue sarcomas managed by the standard of care. MATERIALS AND METHODS A retrospective review was performed on 90 patients who underwent surgical resection of soft tissue sarcomas of the extremity from 2007 to 2015. Patients with minimum 2-year follow-up and adequate operative, pathologic, and clinical outcomes data were included. RESULTS Mean age was 54 ± 18 years with 49 (54.4%) patients being male. Lesions in 77.8% of cases were deep, and 22.2% were superficial to fascia. Following the index surgical resection, a total of 33 (36.7%) patients had positive margins. A total of 17 (18.9%) patients had a local recurrence. Overall, 3-year survival was 92.7%, and 5-year survival was 79.0%. Five-year recurrence-free survival of deep sarcomas was 91.1% versus 58.2% of superficial lesions (p = 0.006). Patients with higher tumor depth had lower odds of experiencing a local recurrence (HR 0.26 [95% CI 0.09-0.72]). Local recurence rates was also associated with positive surgical margins on initial resection (33.3% versus 12.3%) (p = 0.027). CONCLUSIONS In this series, superficial tumor depth was associated with local recurrence of soft tissue sarcomas of the extremity following surgical resection. Positive surgical margins was also associated with local recurrence.

Abstract
» Negative margin resection of musculoskeletal sarcomas is associated with reduced risk of local recurrence.» There is limited evidence to support an absolute margin width of soft tissue or bone that correlates with reduced risk of local recurrence.» Factors intrinsic to the tumor, including histologic subtype, grade, growth pattern and neurovascular involvement impact margin status and local recurrence, and should be considered when evaluating a patient's individual risk after positive margins.» Appropriate use of adjuvant therapy, critical analysis of preoperative advanced cross-sectional imaging, and the involvement of a multidisciplinary team are essential to obtain negative margins when resecting sarcomas.

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 Myxofibrosarcoma (MFS) is a spectrum of aggressive soft tissue fibroblastic neoplasms characterized by variable myxoid stroma, pleomorphism, and a distinctive curved vascular pattern; these tumors are associated with a high likelihood of recurrence. Better local tumor control (a tumor-free margin) is believed to be important to minimize the risk of recurrence, but the effect of surgical resection margin status on local recurrence and survival in MFS is not as well-characterized as it might be. QUESTIONS/PURPOSES (1) Is margin width associated with local recurrence? (2) Is there a relationship between greater margin thickness and improved overall and disease-free survival (DFS)? (3) Is worsening French Federation of Cancer Centers grade associated with local recurrence and poorer overall survival? METHODS Using a database of patients with bone and soft tissue tumors at a tertiary university hospital, we retrospectively reviewed the medical records of 282 patients who had soft tissue sarcomas and who had been surgically treated by a multidisciplinary bone and soft tissue tumor care team between January 2010 and December 2021. Of these 282 patients, 38 were identified as having MFS. Patients who received surgical care for MFS outside our institution (unplanned resection) (four patients) and whose surgical margins were not reported as microscopic numerical data (10) were excluded from the analysis. We estimated survival and local recurrence and examined factors potentially influencing these outcomes. Patient demographics, tumor characteristics, surgical margin distance (in mm), and disease-related outcomes were recorded. The minimum follow-up was 3 months (median 41.5 months, range 3 to 128 months). RESULTS Overall 1-year local recurrence-free rates were 66.7% (95% CI 50% to 88%). Patients with positive margins were more likely to have local recurrence than patients with negative margins (HR 10.91 [95% CI 2.61 to 45.66]; p = 0.001). Patients with an inadequate margin (positive margin or a negative margin of 1 mm or less) had a greater risk of local recurrence (HR 9.96 [95% CI 1.22 to 81.44]; p = 0.032). Patients with positive margins or margins less than or equal to 1 mm had worse 2-year local recurrence-free survival than did those with margins of greater than 1 mm (46.9% [95% CI 16% to 76%] versus 91.7% [95% CI 75% to 100%]; p = 0.005). The mean overall survival was 98 months (95% CI 77.2 to 118.8). The Kaplan-Meier overall 1-, 2- and 5-year estimated rates of survival were 88% (95% CI 75% to 100%), 79.2% (95% CI 64.5% to 97.2%), and 73.5% (95% CI 57.2 % to 94.5%), respectively. Positive surgical margins were associated with decreased overall survival (HR 6.96 [95% CI 1.39 to 34.89]; p = 0.018). There was a mean DFS time of 4.25 months (95% CI 0.92 to 7.59) in microscopically positive patients, 75.5 months (95% CI 37.47 to 113.53) in patients with margins 1 mm or less, and 118 months (95% CI 99.23 to 136.77) in patients with margins over 1 mm. There was a statistical difference between DFS times according to surgical margin classification (p < 0.001). With the numbers we had, we could not detect any difference between the histologic grades determined by the French Federation of Cancer Centers grading system in terms of local recurrence (HR 3.80 [95% CI 0.76 to 18.94]; p = 0.103) and overall survival (HR 6.91 [95% CI 0.79 to 60.13]; p = 0.080). Tumor size was the prognostic factor associated with a higher local recurrence rate among all factors analyzed as univariate (HR 1.18 [95% CI 1.05 to 1.32]; p = 0.004). CONCLUSION A surgical procedure with a sufficient negative surgical margin distance appears to be associated with a lower proportion of patients who experience a local recurrence and is associated with overall patient survival. It is difficult to define what a sufficient margin is, but in our patients, it appears to be greater than 1 mm.Level of Evidence Level III, therapeutic study.

Abstract
Soft tissue sarcomas (STSs) are common cutaneous or subcutaneous neoplasms in dogs. Most STSs are initially treated by surgical excision, and local recurrence may develop in almost 20% of patients. Currently, it is difficult to predict which STS will recur after excision, but this ability would greatly assist patient management. In recent years, the nomogram has emerged as a tool to allow oncologists to predict an outcome from a combination of risk factors. The aim of this study was to develop a nomogram for canine STSs and determine if the nomogram could predict patient outcomes better than individual tumour characteristics. The current study provides the first evidence in veterinary oncology to support a role for the nomogram to assist with predicting the outcome for patients after surgery for STSs. The nomogram developed in this study accurately predicted tumour-free survival in 25 patients but failed to predict recurrence in 1 patient. Overall, the sensitivity, specificity, positive predictive, and negative predictive values for the nomogram were 96%, 45%, 45%, and 96%, respectively (area under the curve: AUC = 0.84). This study suggests a nomogram could play an important role in helping to identify patients who could benefit from revision surgery or adjuvant therapy for an STS.

Abstract
BACKGROUND The quality of surgical margins is the most important factor affecting local control in soft tissue sarcoma (STS). Despite this, there is no universally accepted consensus on the definition of an adequate surgical margin or on which patients should be offered radiation therapy. This study focuses on local control and its prognostic factors in patients with trunk wall and extremity STS. METHODS Adult patients with a final diagnosis of trunk wall or extremity STS referred to a single tertiary referral centre between August 1987 and December 2016 were identified from a prospective institutional database. Patients were treated according to a protocol instituted in 1987. The classification of surgical margins and indications for radiation therapy were based on anatomy and strict definition of surgical margins as metric distance to the resection border. Local treatment was defined as adequate if patients received either surgery with wide margins alone or marginal surgery combined with radiation therapy. Margins were considered wide if the tumour was excised with pathological margins greater than 2.5 cm or with an uninvolved natural anatomical barrier. After treatment, patients were followed up with local imaging and chest X-ray: 5 years for high-grade STS, 10 years for low-grade STS. RESULTS A total of 812 patients were included with a median follow-up of 5.8 (range 0.5-19.5) years. Forty-four patients had a grade 1 tumour: there were no instances of recurrence in this group thus they were excluded from further analysis. Five-year local control in the 768 patients with grade 2-3 STS was 90.1 per cent in patients receiving adequate local treatment according to the protocol. Altogether, 333 patients (43.4 per cent) were treated with wide surgery alone and their 5-year local control rate was 91.1 per cent. Among patients treated with wide surgery alone, deep location was the only factor adversely associated with local relapse risk in multivariable analysis; 5-year local control was 95.3 per cent in superficial and 88.3 per cent in deep-sited sarcomas (hazards ratio 3.154 (95% c.i. 1.265 to 7.860), P = 0.014). CONCLUSION A high local control rate is achievable with surgery alone for a substantial proportion of patients with STS of the extremities or superficial trunk wall.

Abstract
INTRODUCTION Haemorrhagic soft-tissue sarcomas (HSTS) are characterised by aggressive local growth and highly metastatic behaviour. We aimed to describe oncological outcomes and prognostic factors. MATERIALS AND METHODS Retrospective review including 64 patients treated with palliation (n = 7), with limb salvage surgery (LSS) (n = 9), with neoadjuvant radiotherapy (RT) + LSS (n = 12), with LSS + adjuvant RT (n = 30) or amputation (n = 6). Kaplan-Meier survival analysis estimated overall survival (OS), metastasis-free survival (MFS) and local recurrence-free survival (LRFS). After uni- and multivariate analysis, prognostic factors affecting OS, MFS and LRFS were identified. RESULTS Median age was 67 years (IQR 23 years) with median follow-up of 11 months (IQR 28 months). All cases were high grade. Eight (13%) had pulmonary metastases at presentation and another 40 (63%) developed metastases after median 9 months (IQR 19 months). Median OS was 12 months (IQR 38 months), and estimated OS after two-years was 15.9% and 52.9% for patients with and without metastatic disease at presentation, respectively. Improved OS was associated with negative resection margins (p = 0.031), RT (p = 0.045), neoadjuvant RT (versus adjuvant RT, p = 0.044) and amputation (versus LSS, p < 0.001). MFS was 35.1% after two-years. LR occurred in 18 of 51 (35.3%) patients with surgically treated localised disease. LRFS was 63.4% after two-years and significantly affected by a negative margin (p = 0.042) and RT (p = 0.001). CONCLUSION Haemorrhagic soft-tissue sarcomas should be excised, either with amputation or LSS with a clear resection margin. If LSS is attempted, neoadjuvant RT reduces the risk of tumour spillage and early LR, enhances the feasibility of achieving clear resection margins, and offers superior overall survival compared to adjuvant RT.

Abstract
Soft-tissue sarcomas (STS) are rare, but potentially life-threatening malignancies. STS can occur anywhere in the human body with the limbs being the most common site. Referral to a specialized sarcoma center is crucial to guarantee prompt and appropriate treatment. STS treatment strategies should be discussed in an interdisciplinary tumor board to involve expertise from all available resources, including an experienced reconstructive surgeon for an optimal outcome. In many cases, extensive resection is needed to achieve R0 resection, resulting in large defects after surgery. Hence, an evaluation of whether plastic reconstruction might be required is mandatory to avoid complications due to insufficient primary wound closure. In this retrospective observational study, we present data of patients with extremity STS treated at the Sarcoma Center, University Hospital Erlangen, in 2021. We found that complications were more frequent in patients who received secondary flap reconstruction after insufficient primary wound closure compared to patients who received primary flap reconstruction. Additionally, we propose an algorithm for an interdisciplinary surgical therapy of soft-tissue sarcomas regarding resection and reconstruction and present two problematic cases to emphasize the complexity of surgical sarcoma therapy.

[PMID: 36287264 PMCID: PMC9607852 DOI: 10.1007/s00432-022-04423-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Accepted: 10/14/2022] [Indexed: 11/17/2022]
Abstract
Background Over the years, radiotherapy has been established as a tool to improve local control for high-grade sarcomas. Although the European Society for Medical Oncology guidelines has taken notice of a shift toward a neoadjuvant radiotherapy approach, the American Society for Radiation Oncology guidelines clearly favor a neoadjuvant approach, citing debilitating long-term adverse effects when radiotherapy is applied postoperatively. In this study, we examined these irradiation-associated adverse events for adjuvant radiotherapy and focused on the prognostic factors for disease outcome, including local control. Methods In this retrospective study, data for 106 patients with extremity soft-tissue sarcomas diagnosed between 1997 and 2021, of which 40 received adjuvant radiotherapy, were collected from the clinical and radiological information systems of a high-volume sarcoma treatment center. These data were then analyzed for radiation-associated side effects as well as predictive factors for overall survival, disease-free survival, local control, and surgical complications. Results Radiotherapy was beneficial to patients improving local control, especially for high-grade sarcomas, even when those were resected with negative margins. Side effects due to radiotherapy occurred in 87.5% of the patients, and these effects primarily included radiation dermatitis in 67.5%; however, only 40.0% had any adverse event of ≥ grade 2 according to Common Terminology Criteria for Adverse Events. Long-term function-limiting side effects occurred in 45.0% of the patients; 10% exhibited ≥ grade 2 function-limiting adverse events. Greater time between surgery and adjuvant radiotherapy was beneficial for the patients, whereas joint infiltrating sarcomas were associated with more severe long term, function-limiting adverse events. 28.3% of the patients experienced a recurrence at any location (median time 18.35 months) and in 16% the recurrence was local (median time 16.11 months), resulting in 1, 3, and 5 year disease-free survival rates of 74.1, 58.9, and 38.5% and local control rates of 78.7, 61.6, and 42.8% were observed, respectively. Conclusion Recurrences may be avoided with high-dose radiation, especially for high-grade G2 and G3 sarcomas, even after complete R0 resection. This resulted in a low rate of severe long-term function-limiting adverse events. Thus, adjuvant radiotherapy should be seriously considered when planning patient treatment, especially when treating patients that present with high-grade sarcomas.

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
![]()
Bone sarcomas are devastating primary bone cancers that
mostly
affect children, young adults, and the elderly. These aggressive tumors
are associated with poor survival, and surgery remains the mainstay
of treatment. Surgical planning is increasingly informed by positron
emission tomography (PET), and tumor margin identification during
surgery is aided by near-infrared fluorescence (NIRF) imaging, yet
these investigations are confounded by probes that lack specificity
for sarcoma biomarkers. We report the development of a dual-modal
(PET/NIRF) immunoconjugate ([89Zr]Zr-DFO-anti-MT1-MMP-IRDye800CW)
that targets MT1-MMP, a matrix metalloproteinase overexpressed in
high-grade sarcomas. [89Zr]Zr-DFO-anti-MT1-MMP-IRDye800CW
was synthesized via site-specific chemoenzymatic
glycan modification, characterized, and isolated in high specific
activity and radiochemical purity. Saturation binding and immunoreactivity
assays indicated only minor perturbation of binding properties. A
novel mouse model of dedifferentiated chondrosarcoma based on intrafemoral
inoculation of HT1080 WT or KO cells (high and low MT1-MMP expression,
respectively) was used to evaluate target binding and biodistribution.
Fluorescence and Cerenkov luminescence images of [89Zr]Zr-DFO-anti-MT1-MMP-IRDye800CW
showed preferential uptake in HT1080 WT tumors. Ex vivo gamma counting revealed that uptake in MT1-MMP-positive tumors was
significantly higher than that in control groups. Taken together,
[89Zr]Zr-DFO-anti-MT1-MMP-IRDye800CW is a promising dual-modal
sarcoma imaging agent for pre-operative surgical planning and intraoperative
surgical guidance.

Abstract
Background and Objectives After diagnosing a primary bone tumor involving the forearm, various excision strategies and reconstruction methods must be considered. This study explored the oncological and functional outcomes of limb salvage surgery for primary malignant bone tumors in the forearm. Methods Patients with primary forearm bone tumors (n = 369) were retrospectively analyzed between 2000 and 2017. There were 266 patients with radial tumors, and 46 (17.3%) were malignant, whereas 103 patients had ulnar lesions and 22 (21.4%) were malignant tumors. The oncological results, prognostic factors, and functional results after limb salvage surgery of forearm malignancies were analyzed. Results The follow-up averaged 72.1 (7–192, median 62.5) months. Fifty-six patients who received limb salvage surgery were included in the final evaluation. Radius resection was performed in 38 patients, and distal radius (25 patients) was most frequent. Ulnar resection was performed in 18 patients, and the proximal ulna (13 patients) was most frequent. The surgical margins obtained were intralesional in 3 patients, marginal in 8 patients and wide in 45 patients. Local recurrence occurred in 11 patients (19.6%), and distant metastasis occurred in 14 patients (25%). The 5-year recurrence-free survival rate was 79.8%. Unplanned excision, ulnar involvement, proximal forearm location and inadequate surgical margins were associated with recurrence. The overall 5-year and 10-year survival rates were 83.5 and 71.7%, respectively. Distant metastasis was a poor prognostic factor for the survival rate. Forty-two patients were evaluated by MSTS score with an average of 27.9 ± 1.5. Conclusions The incidence of radial malignant tumors is higher than that of ulnar lesions. The distal radius and the proximal ulna are the most frequently involved sites. Unplanned excisions, ulnar tumors, proximal forearm tumors, and inadequate surgical margin are the risk factors for local recurrence. Distant metastasis is an independent poor prognostic factor of death. The oncology control and functional results of limb salvage surgery were satisfactory.

Abstract
Background Primary bone and soft tissue sarcoma treatment includes surgical resection, with or without peri-operative chemoradiotherapy. The aim of surgery is to achieve complete excision, to prevent localised recurrence and achieve cure. For various reasons, excision with adequate margins is not always possible. Our aim is to assess the occurrence of unexpected positive margins following primary excision within a tertiary centre and the impact on patient outcomes. Methods A retrospective analysis of 567 patients discussed at the Royal National Orthopaedic Hospital Multi-disciplinary team (MDT) meeting with positive margins between 1999-2020 was performed. Exclusion criteria included: excisions performed externally and lesions treated with curettage. Information gathering from electronic records highlighted 23 cases with unexpected positive margins following primary excision. Results All patients pre-operatively expected to achieve complete primary resection. The median age was 60 years (8-92), 10M:13F. Tumour location included lower limb (12), upper limb (six), pelvis (two) and trunk (three); eight bone tumours and 15 soft tissue. The overall recurrence rate was 30.4% (7/23). In those recommended for re-excision (n=16), the recurrence rate was 31.25% (5/16). Of the patients not initially recommended for re-excision (n=7), four proceeded to surveillance alone with 50% recurrence (2/4), both with metastatic disease not surviving to follow-up. A further three patients underwent post-operative radiotherapy alone with no recurrences at follow-up, one patient not surviving for further treatment due to stroke. The mean follow-up for patients was 3.1 years. Conclusion When positive margins do occur unexpectedly, the impact due to the need for further treatment and ultimately increased risk of recurrence can be significant. Results can be compared to those for unplanned excisions. Therefore, surgeons should be aware of the different circumstances in which positive margins occur to help guide treatment planning and managing patient expectations.

Abstract
BACKGROUND Limited data are available to inform the risk of readmission and short-term mortality in musculoskeletal oncology. The goal of this study was to identify factors independently associated with 30-day readmission and 90-day mortality following surgical resection of chondrosarcoma. METHODS We retrospectively reviewed 6653 patients following surgical resection of primary chondrosarcoma in the National Cancer Database (2004-2017). Both demographic and clinicopathologic variables were assessed for correlation with readmission and short-term mortality utilizing univariate and multivariate logistic regression modeling. RESULTS Of 220 readmissions (3.26%), risk factors independently associated with an increased risk of unplanned 30-day readmission included Charlson-Deyo Comorbidity Index (CDCC) (odds ratio [OR] 1.31; p = 0.027), increasing American Joint Committee on Cancer (AJCC) stage (OR 1.31; p = 0.004), undergoing major amputation (OR 2.38; p = 0.001), and axial skeletal location (OR 1.51; p = 0.028). A total of 137 patients died within 90 days of surgery (2.25%). Risk factors associated with increased mortality included the CDCC (OR 1.60; p = 0.001), increasing age (OR 1.06; p < 0.001), having Medicaid insurance status (OR 3.453; p = 0.005), living in a zip code with a higher educational attainment (OR 1.59; p = 0.003), increasing AJCC stage (OR 2.32; p < 0.001), longer postoperative length of stay (OR 1.015; p = 0.033), and positive surgical margins (OR 2.75; p = 0.001). Although a majority of the cohort did not receive radiation therapy (88.8%), receiving radiotherapy (OR 0.132; p = 0.010) was associated with a decreased risk of short-term mortality. CONCLUSIONS Several tumor, treatment, and patient factors can help inform the risk of readmission and short-term mortality in patients with surgically treated chondrosarcoma.

Abstract
Simple Summary Many classifications to assess margins status for soft tissue sarcomas are reported in the literature. Most of the series are heterogeneous and variable in size, making it difficult to compare results from study to study. Thus, which is the best way to assess margins in order to predict the risk of local recurrence is still debated. The aim of this narrative review is to provide a comprehensive assessment of the literature on margins, and to highlight the need for a uniform description of the margin status for patients with soft tissue sarcomas (STS). Abstract Adequacy of margins must take into consideration both the resection margin width (quantity) and anatomic barrier (quality). There are several classification schemes for reporting surgical resection margin status for soft tissue sarcomas (STS). Most of the studies regarding treatment outcomes in STS included all histologic grades and histological subtypes, which include infiltrative and non-infiltrative subtypes and are very heterogeneous in terms of both histologic characteristics and treatment modalities (adjuvant treatments or not). This lack of consistency makes it difficult to compare results from study to study. Therefore, there is a great need for evidence-based standardization concerning the width of resection margins. The aim of this narrative review is to provide a comprehensive assessment of the literature on margins, and to highlight the need for a uniform description of the margin status for patients with STS. Patient cases should be discussed at multidisciplinary tumor boards and treatments should be individualized to clinical and demographic characteristics, which must include also a deep knowledge of specific histotypes behaviors, particularly infiltrative ones.

Abstract
Resection of soft-tissue sarcoma (STS) is accompanied by a high rate of tumor-positive surgical margins (14%-34%), which potentially lead to decreased disease-free survival. Vascular endothelial growth factor A is overexpressed in malignant tumors, including STS, and can be targeted with bevacizumab-800CW during fluorescence-guided surgery for real-time tumor detection. In this phase 1 clinical trial, we determined the feasibility, safety, and optimal dose of bevacizumab-800CW for fluorescence-guided surgery in STS for in vivo and ex vivo tumor detection. Methods: Patients with a histopathologic diagnosis of STS were included. In the dose-escalation phase, patients received bevacizumab-800CW intravenously 3 d before surgery (10, 25, and 50 mg; n = 8). In the subsequent dose-expansion phase, 7 additional patients received bevacizumab-800CW at the optimal dose. Fluorescence images were obtained in vivo and ex vivo during all stages of standard care. The optimal dose was determined by calculating in vivo and ex vivo tumor-to-background ratios (TBR) and correlating these results with histopathology. Results: Fifteen patients with STS completed this study. All tumors could be visualized during in vivo and ex vivo imaging. The optimal bevacizumab-800CW dose proved to be 10 mg, with a median in vivo TBR of 2.0 (±0.58) and a median ex vivo TBR of 2.67 (±1.6). All 7 tumor-positive margins could be observed in real time after surgical resection. Conclusion: GS using 10 mg of bevacizumab-800CW is feasible and safe for intraoperative imaging of STS, potentially allowing tumor detection and margin assessment during surgery. An additional follow-up phase 2 study is needed to confirm the diagnostic accuracy.

Abstract
AIM To construct and validate a radiomics-based machine-learning method for preoperative prediction of distant metastasis (DM) from soft-tissue sarcoma. MATERIALS AND METHODS Seventy-seven soft-tissue sarcomas were divided into a training set (n=54) and a validation set (n=23). The performance of three feature selection methods (ReliefF, least absolute shrinkage and selection operator [LASSO], and regularised discriminative feature selection for unsupervised learning [UDFS]) and four classifiers, random forest (RF), logistic regression (LOG), K nearest neighbour (KNN), and support vector machines (SVMs), were compared for predicting the likelihood of DM. To counter the imbalance in the frequencies of DM, each machine-learning method was trained first without subsampling, then with the synthetic minority oversampling technique (SMOTE). The performance of the radiomics model was assessed using area under the receiver-operating characteristic curve (AUC) and accuracy (ACC) values. RESULTS The performance of the LASSO and SVM algorithm combination used with SMOTE was superior to that of the algorithm combination alone. The combination of SMOTE with feature screening by LASSO and SVM classifiers had an AUC of 0.9020 and ACC of 91.30% in the validation dataset. CONCLUSION A machine-learning model based on radiomics was favourable for predicting the likelihood of DM from soft-tissue sarcoma. This will help decide treatment strategies.

The role of surgical margin quality in myxofibrosarcoma and undifferentiated pleomorphic sarcoma. Eur J Surg Oncol 2020; 47:1756-1762. [PMID: 33342698 DOI: 10.1016/j.ejso.2020.11.144] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2020] [Revised: 11/22/2020] [Accepted: 11/26/2020] [Indexed: 12/12/2022] Open
Abstract
OBJECTIVES The effect of margin quality as a barrier against infiltration of soft-tissue sarcomas (STSs) has been unclear. We aimed to investigate the effect of margin quantity and quality on local control for myxofibrosarcoma (MFS) and undifferentiated pleomorphic sarcoma (UPS). METHODS 278 patients with a localised MFS and UPS were studied. Margin quality was categorized into five types; type 1, pseudocapsule/reactive zone; type 2, fat/fibrofatty tissue; type 3, muscle; type 4, fascia; type 5, periosteum. RESULTS The 5-year cumulative LR incidence was 22% and 13% in patients with positive and 0.1-9.9 mm margins, respectively, but decreased to 3% with ≥10.0 mm margins (p = 0.009); the cumulative LR incidence was significantly lower in patients with ≥10.0 mm margins than those with positive margins (p = 0.033) but was not significantly different in those with 0.1-9.9 mm margins (p = 0.183). In patients with 0.1-9.9 mm margins, the cumulative LR incidence was affected by margin quality; type 4 and 5 provided an LR risk less than 5% (p < 0.001), which was similar to those with margins ≥10.0 mm. Combining these two factors together, the LR risk in patients with positive or 0.1-9.9 mm margins without fascia/periosteum was approximately 11 × higher than patients with 0.1-9.9 mm margins with fascia/periosteum or margins ≥10.0 mm (p = 0.002). CONCLUSIONS A resection margin of 0.1-9.9 mm with fascia or periosteum provided a similar LR risk profile to ≥10 mm margins with any margin quality, which provided the lowest LR risk. The quality of fascial or periosteal tissue margins may be equivalent to a margin quantity of 10 mm as a barrier to LR.

Abstract
Alveolar rhabdomyosarcomas (ARMS) are rare entities that occur predominantly on the extremities and represent 20% of rhabdomyosarcomas. Other common locations include the peri-rectal and perineal regions, head and neck, and genitourinary system. To our knowledge, this presentation is the first case of alveolar rhabdomyosarcoma of the chest wall reported in the literature. Here, we describe a case of a 64-year-old man with alveolar rhabdomyosarcomas who underwent a chest wall resection. The defect was reconstructed with polypropylene mesh and latissimus dorsi muscle. Our patient did not show recurrence ten months after complete resection. The present paper describes our surgical approach to a case of primary alveolar rhabdomyosarcoma of the chest wall in an adult. The authors discuss the principal judgment criteria for successful surgical resection and prognosis, highlighting the relevance of chest wall reconstruction and their complementary aspects in the multimodal management of this rare entity.

The Effect of Resection Margin on Local Recurrence and Survival in High Grade Soft Tissue Sarcoma of the Extremities: How Far Is Far Enough? Cancers (Basel) 2020; 12:cancers12092560. [PMID: 32911853 PMCID: PMC7563962 DOI: 10.3390/cancers12092560] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Revised: 08/30/2020] [Accepted: 09/05/2020] [Indexed: 12/20/2022] Open
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.

Low-grade soft-tissue sarcomas: What is an adequate margin for local disease control? Surg Oncol 2020; 35:303-308. [PMID: 32961431 DOI: 10.1016/j.suronc.2020.08.022] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2020] [Revised: 07/27/2020] [Accepted: 08/19/2020] [Indexed: 11/23/2022]
Abstract
BACKGROUND Whilst the resection margin is an established factor predictive of local control of soft-tissue sarcomas (STSs), the adequacy of margin width for low-grade STSs has been rarely described. We aimed to investigate the margin adequacy and its prognostic relevance in low-grade STSs. METHODS 109 patients who underwent surgical treatment for a low-grade STS were studied. The prognostic value of margin status was evaluated according to the R-, R+1-classification, and width in millimetres. RESULTS The 10-year local recurrence (LR) rates were 6%, 27%, 54% in R0, R1, and R2, respectively (p < 0.001), according to the R-classification. The R+1-classification resulted in a decreased LR rate in R1, but no major differences in LR rates in R0 and R2; 7%, 14%, 54% in R0, R1, and R2, respectively (p < 0.001). When classified by metric distance, 10-year LR rates were 0%, 8%, and 38% by ≥ 2.0 mm, 0.1-1.9 mm, and 0 mm margins, respectively (p < 0.001). Patients with close margins (0.1-1.9 mm) who received adjuvant radiotherapy had a trend toward lower LR risk than those without radiotherapy (10-year, 4% vs. 12%; p = 0.406). The 5 and 10-year disease-specific mortality was 9% and 13%, respectively; margin width was not associated with disease-specific mortality but LR was a poor prognostic factor for survival (p = 0.003). CONCLUSION Whilst negative margin provided local control over 90%, excellent local control was achieved with microscopic margins ≥2 mm. The role of margins is more important than radiotherapy in local control. Margins do not determine survival, but LR is associated with a poor prognosis.

Abstract
OBJECTIVES There remains no consensus on what constitutes an adequate margin of resection for non-infiltrative soft-tissue sarcomas (STSs). We aimed to investigate the role of resection margins in millimetres for non-infiltrative STSs. METHODS 502 patients who underwent surgical resection for a localized, non-infiltrative, high-grade STSs were studied. The prognostic significance of margin width was analysed and compared with the conventional R- and R+1-classification of surgical margins. RESULTS The overall local recurrence (LR) rate was 13%; 9% and 27% with negative and positive margins, respectively (p < 0.001). In patients with negative margins, the LR rates were greater than 10% in patients with margins ≤5.0 mm but reduced to less than 4% with margins >5.0 mm. When classified by the R- (or R+1)-classification, the 5-year cumulative LR incidence was 8%, 23% (16%), and 31% for R0, R1, and R2, respectively, which did not stratify the LR risk with negative margins. On the other hand, an accurate risk stratification was possible by metric distance; the 5-year cumulative incidence of LR was 29%, 10%, and 1% with 0 mm, 0.1-5.0 mm, and >5.0 mm, respectively (p < 0.001). This classification also stratified the LR risk in patients with or without adjuvant radiotherapy. CONCLUSION While a negative margin is essential to optimize local control in patients with non-infiltrative STSs, surgical margin width greater than 5 mm minimises the risk of local failure regardless of the use of adjuvant radiotherapy.

Abstract
BACKGROUND Combined modality of radiotherapy and surgery is the standard of treatment of soft tissue sarcomas (STS). The goal of this study was to assess whether a Combined Onco-Plastic (COP) surgical approach in the setting of neo-adjuvant radiotherapy can improve the oncologic outcomes of STS and reduce the rate of wound complications. METHODS We performed a retrospective review of all patients with STS treated at a single sarcoma centre (St Vincent's Hospital, Melbourne) between 2007 and 2018. Patients were stratified into two groups based on whether they have received the COP approach or were closed primarily by the orthopaedic surgeon. We analysed oncological outcomes and rate of wound complications. RESULTS A total of 546 patients with comparable demographics and tumor characteristics were included. The COP approach was performed in 75.6% of the patients. Wide margins were obtained in 97.4% of the cases, and this was significantly higher in the COP group (p < 0.001). The cumulative rate of local recurrence was 4.9%, with a 52% risk reduction in the COP approach, although this reduction was not significant (HR = 0.48; 95% CI 0.21-1.06; p = 0.070). The COP approach had better disease free survival (DFS) (aHR 1.86, 95% CI 1.45-2.37; p < 0.001) and Overall survival (risk of death aHR 0.49; 95% CI 0.30-0.79; p = 0.004). The overall wound complication rate was 18.6% with no difference between the two groups. CONCLUSION A planned collaboration between the orthopaedic oncologist and the plastic surgeon is beneficial in the treatment of STS after neo-adjuvant radiotherapy, allowing remarkably good oncological outcomes and a low rate of wound complications.

Abstract
The recurrence rate of soft tissue and bone sarcomas strongly correlates to the status of the surgical margin after excision, yet excessive removal of tissue may lead to distinct, otherwise avoidable morbidity. Therefore, adequate margination of sarcomas both pre- and intra-operatively is a clinical necessity that has not yet fully been met. Current guidance for soft-tissue sarcomas recommends an ultrasound scan followed by magnetic resonance imaging (MRI). For bone sarcomas, two plane radiographs are required, followed similarly by an MRI scan. The introduction of more precise imaging modalities may reduce the morbidity associated with sarcoma surgery; the PET-CT and PET-MRI approaches in particular demonstrating high clinical efficacy. Despite advancements in the accuracy in pre-operative imaging, translation of an image to surgical margins is difficult, regularly resulting in wider resection margins than required. For soft tissue sarcomas there is currently no standard technique for image guided resections, while for bone sarcomas fluoroscopy may be used, however margins are not easily discernible during the surgical procedure. Near infra-red (NIR) fluorescence guided surgery offers an intra-operative modality through which complete tumour resection with adequate tumour-free margins may be achieved, while simultaneously minimising surgical morbidity. NIR imaging presents a potentially valuable adjunct to sarcoma surgery. Early reports indicate that it may be able to provide the surgeon with helpful information on anatomy, perfusion, lymphatic drainage, tumour margins and metastases. The use of NIR fluorochromes have also been demonstrated to be well tolerated by patients. However, prior to widespread implementation, studies related to cost-effectiveness and the development of protocols are essential. Nevertheless, NIR imaging may become ubiquitous in the future, carrying the potential to transform the surgical management of sarcoma.

Abstract
OPINION STATEMENT For localized extremity soft tissue sarcoma (eSTS), treatment is individualized and each patient needs to be evaluated by a multidisciplinary team at a referral sarcoma center specialized in the care of sarcoma. For a majority of patients, treatment for eSTS involves limb-salvage surgery, with or without the addition of radiation therapy. Surgery should only be performed by surgeons specifically fellowship trained in the resection of eSTS. Surgery alone may be considered for small, low-grade, and superficial tumors as long a wide (≥ 2 cm) margin can be achieved. In cases where a less than wide negative margin can be achieved, radiation therapy should be utilized to facilitate a planned close margin resection to preserve critical structures (such as nerves, blood vessels, and bone) without a significant impact on oncologic outcomes. Soft tissue sarcomas are rare, and as such patients often present following an inadvertent excision. In these situations, we recommend preoperative radiation and wide tumor bed re-excision, as rates of residual tumor can be high in this scenario. While there is large amount of evidence to support the use of radiotherapy to enhance local tumor control, the evidence to support the use of chemotherapy to enhance local tumor control is lacking, and as such cannot be recommended for all patients.

Abstract
Adequacy of surgical resection margins for soft tissue sarcomas are poorly defined because of the various classifications and definitions used in prior studies of heterogeneous patient cohorts and inconsistent margin sampling protocols. Surgical resection margins of 166 primary, high-grade, pleomorphic sarcomas of the extremity or trunk were classified according to American Joint Committee on Cancer R and Musculoskeletal Tumor Society categories, as well as by metric distance and tissue composition. None of the cases were treated with neoadjuvant therapy. Multivariable competing risk regression models were evaluated and optimal surgical resection margins for each classification system were defined. Minimum safe tumor clearance was 5 mm without use of adjuvant radiotherapy and 1 mm with adjuvant radiotherapy. Predictive accuracy of margin classification systems was compared by area under receiver-operating characteristic curves generated from logistic regression of 2½-year local recurrence-free survival and other standard tests of diagnostic accuracy. The Musculoskeletal Tumor Society and margin distance classifications performed similarly, both of which showed higher sensitivity and negative predictive value compared to the American Joint Committee on Cancer R classification. The prognostic power of close or positive margins in prediction models significantly increased when six or more slides were submitted for assessment of surgical resection margins. Surgical resection margins for soft tissue sarcoma should be reported using the Musculoskeletal Tumor Society classification or metric distance to the closest resection margin. Musculoskeletal Tumor Society wide/radical margins or tumor clearances of 5 mm (without adjuvant radiotherapy) or 1 mm (with adjuvant radiotherapy) appear to define the minimum safe surgical resection margins necessary to decrease the likelihood of local recurrence of high-grade pleomorphic sarcomas of the extremity or trunk.

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
BACKGROUND Scalp angiosarcoma is a rare and highly aggressive cutaneous malignancy with poor prognosis and high recurrence rate. Multimodality approach is currently the treatment protocol for resectable angiosarcoma, including wide local excision and postoperative radiation. This single-institution study reviews the 18-year experience of the surgical treatment of scalp angiosarcomas. METHODS A retrospective chart review was performed on patients with scalp angiosarcoma who received wide local excision and free flap reconstruction from 2001 to 2018. The type of free flap, safety margin, outer cortex burring, and dose for radiation were recorded. Kaplan-Meier plots were computed. RESULTS Eight male patients (mean age of 74.4 years old) were enrolled in the series. Tumor sizes ranged from 3 × 3 to 8 × 13 cm. All patients underwent wide local excision and outer cortex burring (cortical curettage). Seven (87.5%) scalp defects were reconstructed with anterolateral thigh free flap. All patients received adjuvant radiation therapy for tumor bed and margins. Chemotherapy was adopted for the management of local recurrence (37.5%) or distant metastasis (37.5%). The 2-year and 5-year survival rates are 72.9% and 38.9%, respectively, and 1-year and 2-year disease-free rates are 37.5% each. CONCLUSION Scalp angiosarcoma is a rare and highly aggressive cutaneous malignancy with poor prognosis. Anterolateral thigh free flap is a good reconstructive option due to its ability to cover large cutaneous defects with minimal need for skin grafting. Multimodal treatment protocol, including wide local excision with cortical curettage, and adjuvant radiation (regular basis) and chemotherapy (local recurrence or distant metastasis) may offer improved 1-year survival rate (100%).

The role of radiation therapy and margin width in localized soft-tissue sarcoma: Analysis from the US Sarcoma Collaborative. J Surg Oncol 2019; 120:325-331. [PMID: 31172531 DOI: 10.1002/jso.25522] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2019] [Revised: 05/12/2019] [Accepted: 05/13/2019] [Indexed: 01/25/2023]
Abstract
BACKGROUND AND OBJECTIVES Soft-tissue sarcomas (STSs) are often treated with resection and radiation (RT)±chemotherapy. The role of RT in decreasing resection width to achieve local control is unclear. We evaluated RT on margin width to achieve local control and local recurrence (LR). METHODS From 2000 to 2016, 514 patients with localized STS were identified from the US Sarcoma Collaborative database. Patients were stratified by a margin and local control was compared amongst treatment groups. RESULTS LR was 9% with positive, 4.2% with ≤1 mm, and 9.3% with >1 mm margins (P = .315). In the ≤1 mm group, LR was 5.7% without RT, 0% with preoperative RT, and 0% with postoperative RT (P < .0001). In the >1 mm group, LR was 10.2%, 0%, and 3.7% in the no preoperative and postoperative RT groups, respectively (P = .005). RT did not influence LR in patients with positive margins. In stage I-III and II-III patients, local recurrence-free survival was higher following RT (P = .008 and P = .05, respectively). CONCLUSIONS RT may play a larger role in minimizing LR than margin status. In patients with positive margins, RT may decrease LR to similar rates as a negative margin without RT and may be considered to decrease the risk of LR with anticipated close/positive margins.

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 Soft tissue sarcomas (STS) represent a rare and heterogeneous group of tumors. We sought to characterize national trends in referral patterns, treatment strategies, and overall survival (OS) over the course of a decade. METHODS Adult patients with extra-abdominal STS were identified using the National Cancer Database and categorized by diagnosis year (2005-2009 and 2010-2014). High-volume hospitals (HVH) were defined as those >90th percentile in volume of STS patients treated, and others were defined as low-volume hospitals (LVH). Standard statistical methods were used to compare treatment strategies and OS by diagnosis period. RESULTS Of 55,212 patients, 25,469 (46.1%) were diagnosed in 2005-2009 and 29,743 (53.9%) in 2010-2014. Despite increased utilization of neoadjuvant radiation therapy (26.6% vs. 34.8%, P < 0.001), the rate of R0 resections did not change (75.0% vs. 74.8%, P = 0.067). Furthermore, at a national level, OS did not improve over time (HR 0.99, 95% CI 0.96-1.01). When outcomes were stratified by volume, treatment at HVH compared to LVH was associated with improved rates of R0 resection (OR 1.27, 95% CI 1.20-1.35) and OS (HR 0.92, 95% CI 0.89-0.95). Moreover, there was a modest improvement in OS at HVH (HR 0.95, 95% CI 0.91-1.00), but not at LVH (HR 1.01, 95% CI 0.97-1.04). However, referral to HVH did not change over time (40.7% vs. 40.7%, P = 0.91). CONCLUSION OS for STS did not change at a national level over the course of a decade, although it improved at HVH. Further outcome improvements will likely require more effective systemic therapies.

Abstract
BACKGROUND This static cadaveric model pilot study evaluated the agreement between planned and resected margins of simulated soft tissue tumors (SSTT) using skin fiducial markers for computerized navigation registration. METHODS Markers were applied before magnetic resonance imaging scans of lower extremities implanted with SSTT. A navigation pointer was used for registration and to guide SSTT resection with approximately 10 mm planned margins. Digital calipers were used to measure resection margins. Kolmogorov-Smirnov tests were used to confirm measurement normality. A one-sample t test was used to determine measurement group differences (P ≤ 0.05). Bland-Altman analysis and histogram plots compared planned and resected margins. RESULTS Ninety-eight resection margins were measured. The planned margin mean was 10.0 mm (95% confidence interval [CI] = 9.8-10.2 mm) and the resected margin mean was 11.5 mm (95% CI = 11.0-12.1 mm). One-sample t test results identified a 0.75 mm, 95% CI = 0.5-0.99 mm difference (P < 0.001). Good measurement agreement was observed with 94.9% (93/98) of resections occurring within two standard deviations of the mean measurement difference. CONCLUSIONS Skin fiducial marker use for computerized navigation system registration displayed promising results. With further research, these markers may become an effective, noninvasive method for aiding in soft tissue tumor resection.

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
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 are derived from tissues of mesenchymal origin. Although local recurrence following surgical resection is the characteristic challenge in their management, 40% dogs with high-grade tumours may also develop metastatic disease, despite successful local control. Soft tissue sarcoma is a complex disease and there are many uncertainties regarding the biology and optimal clinical management. There are currently no diagnostic tests that can reliably predict the amount of surgical margin required for a particular tumour, so there can be a mismatch between treatment and disease. Historically, the tendency has been to always recommend wide excision margins but this is not fully supported by recent evidence. A selection bias for less aggressive soft tissue sarcomas in primary care practice can account for good outcomes that are achieved despite narrow surgical excision margins. On the other hand, inappropriately conservative treatment will adversely affect outcomes for patients with more aggressive disease. This review provides an update on the current understanding of management of canine soft tissue sarcomas.

Abstract
Soft-tissue sarcoma of the limbs or the trunk wall determine a heterogeneous group of tumours that tends to receive a more individualized approach. The surgeon in charge with soft-tissue sarcoma has to be familiar with these tumours in order to deliver an adequate treatment. Most important is the initial diagnostic procedure, comprising imaging with MRI, a core needle biopsy, and in France, referral to a centre of expertise within the clinical network NETSARC. Prior to surgery, a multidisciplinary conference determines its moment and the extent of surgical resection within the frame of a multidisciplinary approach, and also plans reconstructive surgery, when needed. A standardized operative report summarizes items necessary to describe the resection quality (i.e. tumour seen, tumour infiltrated?). In multidisciplinary staff meetings, they are compared to margins measured by the pathologist on the operative specimen. Hence, resection quality is determined collegially and defined by resection type R (R0, R1, R2) as a qualitative result. The quality of resection directly determines the 5-year risk of local recurrence, estimated between 10 and 20% in specialized centres, with the objective to attain 10%. Early rehabilitation favours better functional outcome. The surgeon's experience with soft-tissue sarcoma, as part of a multidisciplinary treatment, is key in achieving the best adequacy between oncological resection and favourable functional outcome. In France, a specific university course for soft-tissue sarcoma will be set-up.

Abstract
Abstract
Background
Extremity soft-tissue sarcomas comprise a range of distinct histological subtypes. This study aimed to characterize the patterns of disease relapse in patients undergoing resection of primary extremity soft-tissue sarcoma.
Methods
All patients who had resection of primary extremity soft-tissue sarcoma at the Royal Marsden Hospital between January 2004 and January 2014 were identified from an institutional database.
Results
In the period examined, 556 patients underwent resection. The most common histological subtypes were undifferentiated pleomorphic sarcoma (169 patients, 30·4 per cent), well differentiated liposarcoma (63, 11·3 per cent), myxoid liposarcoma (62, 11·2 per cent), myxofibrosarcoma (54, 9·7 per cent) and leiomyosarcoma (39, 7·0 per cent). Local recurrence-free survival (LRFS) did not differ significantly between histological subtypes (P = 0·222). Distant metastasis-free survival (DMFS) and disease-specific survival (DSS) were found to differ significantly between subtypes (P < 0·001 for both DMFS and DSS), with the worst outcomes in patients with undifferentiated pleomorphic sarcoma (5-year survival rate: 56·8 (95 per cent c.i. 52·5 to 61·1) per cent for DMFS; 60·1 (55·6 to 64·6) per cent for DSS). However, on multivariable analysis, histological subtype was not found to be independently prognostic for LRFS, DMFS or DSS. Metastatic disease developed in 149 patients, with the lungs being the most common site of first metastasis (120 patients, 80·5 per cent). The site of first metastasis differed between subtypes, with extrapulmonary metastases predominant in myxoid liposarcoma (11 of 13 patients; P < 0·001).
Conclusion
Although histological subtype was not found to be an independent prognostic factor for oncological outcomes, the site of first metastasis differed significantly between subtypes.

Tumour-free margins in vulvar squamous cell carcinoma: Does distance really matter? Eur J Cancer 2016; 65:139-49. [PMID: 27497345 DOI: 10.1016/j.ejca.2016.07.006] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2016] [Revised: 06/29/2016] [Accepted: 07/04/2016] [Indexed: 11/26/2022]
Abstract
BACKGROUND There is no consensus on the width of tumour-free margins after surgery for vulvar squamous cell carcinoma (VSCC). Most current guidelines recommend tumour-free margins of ≥8 mm. The aim of this study was to investigate whether a margin of <8 mm is associated with an increased risk of local recurrence in VSCC. METHODS A meta-analysis of the available literature and a cohort study of 148 VSCC patients seen at a referral centre from 2000 to 2012 was performed. The primary end-point of the cohort study was a histologically confirmed ipsilateral local recurrence within 2 years after primary treatment in relation to the margin distance. RESULTS Based on 10 studies, the meta-analysis showed that a tumour-free margin of <8 mm is associated with a higher risk of local recurrence compared to a tumour-free margin of ≥8 mm (pooled risk ratio, 1.99 [95% confidence interval {CI}: 1.13-3.51], p = 0.02). In the cohort study, we found no clear difference in the risk of local recurrence in the <8 versus ≥8 mm group; however, 40% of the patients in the <8 mm group received additional treatment. Tumour-positive margin was the only independent risk factor for local recurrence in the multivariable analysis (hazard ratio, 0.21 [95% CI: 0.08-0.55]). CONCLUSIONS This work provides important data to question the commonly used 8-mm margin as a prognosticator for local recurrence. More research is needed to address the question of whether additional treatment improves the prognosis in patients with a tumour-free margin of <8 mm.

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.

Eur J Surg Oncol 2016; 42:899-906. [PMID: 27107792 DOI: 10.1016/j.ejso.2016.03.026] [Citation(s) in RCA: 50] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2016] [Revised: 03/04/2016] [Accepted: 03/21/2016] [Indexed: 12/20/2022] Open
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.

Extended resection including adjacent organs and Ki-67 labeling index are prognostic factors in patients with retroperitoneal soft tissue sarcomas. World J Surg Oncol 2016; 14:43. [PMID: 26911364 PMCID: PMC4765233 DOI: 10.1186/s12957-016-0810-z] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2015] [Accepted: 02/17/2016] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Because retroperitoneal soft tissue sarcomas (RPS) are extremely rare, there is a significant lack of clinicopathologic information to optimize the treatment strategy. The aim of this study was to evaluate the prognostic factors in RPS, with particular focus on the Ki-67 labeling index (LI). METHODS We included the data from a total of 23 patients who received treatment for primary RPS at a single center. The variables analyzed in this study included tumor size, histological type, malignancy grade, necrosis, mitosis, and Ki-67 LI. Kaplan-Meier and Cox proportional regression analyses of overall survival (OS) were performed to identify significant prognostic variables. RESULTS Of the 23 patients who underwent surgical resection, 9 (39%) underwent simple resection of the tumor and 14 (61%) extended resection including the adjacent organs. In the univariate analysis, a simple tumor resection and a high Ki-67 LI were associated with shorter OS. The multivariate analysis revealed that simple tumor resection and a high Ki-67 LI were independent negative prognostic factors for OS. CONCLUSIONS Our results suggested that combined resection of RPS and its adjacent organs improved OS. Pathologically, a high Ki-67 LI was significantly associated with negative prognosis.

Abstract
Soft tissue sarcomas of the upper extremity represent a severe threat for the patient and a difficult task for the treatment team. Due to the complex anatomy of the arm, most sarcomas involve valuable functional structures. Nonetheless, a large portion of the patients can be treated in a limb-sparing manner, and surgery is the mainstay of local tumor control. This review gives an overview of the disease entities and their epidemiology, on necessary patient work-up, staging, and imaging modalities, as well as the importance of interdisciplinary decision-making. The surgical therapies and principles of tumor excision are outlined, as well as reconstructive options. Furthermore, adjuvant treatments are discussed with a special focus on the various application techniques for radiation therapy. In spite of established treatment algorithms, each case is an individual challenge and individually tailored therapy is required. This aspect is illustrated by presenting three comprehensive cases demonstrating useful strategies. A summary of the relevant literature is given.
