Abstract
BACKGROUND To investigate the difference in efficacy of re-excision in synovial sarcoma patients with and without residual tumor following unplanned excision, and to compare the prognostic outcomes of immediate re-excision versus waiting for local recurrence. METHOD This study included synovial sarcoma patients who underwent re-excision at our center between 2009 and 2019, categorized into groups based on unplanned excision and local recurrence. Analyzed endpoints included overall survival (OS), local recurrence-free survival (LRFS), and distant relapse-free survival (DRFS). Prognostic factors associated with these three different survival outcomes were analyzed through the use of Kaplan-Meier curves and Cox regression approaches. RESULT In total, this study incorporated 109 synovial sarcoma patients, including 32 (29.4%) with no residual tumor tissue identified after re-excision, 31 (28.4%) with residual tumor tissue after re-excision, and 46 (42.2%) with local recurrence after initial excision. Patients were assessed over a median 52-month follow-up period. The respective 5-year OS, 5-year LRFS, and 5-year DRFS rates were 82.4%, 76.7%, and 74.2% for the nonresidual group, 80.6%, 80.4%, and 77.3% for the residual tumor tissue group, and 63.5%, 50.7%, and 46.3% for the local recurrence group. There was no significant difference in OS of nonresidual group and residual group patients after re-excision (p = 0.471). Concurrent or sequential treatment with chemotherapy and radiotherapy significantly reduced the risk of metastasis and mortality when compared with noncombined chemoradiotherapy, and was more effective in the local recurrence group (p < 0.05). CONCLUSION Prompt and adequate re-excision is crucial for patients with synovial sarcoma who undergo initial inadequate tumor excision, and their prognosis is significantly better compared with patients who delay re-excision until local recurrence.

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 In soft tissue sarcomas, the oncological and functional outcomes between planned excision and unplanned excision with additional wide resection remains controversial. The purpose of this study is to determine the impact of unplanned excision on oncological and functional outcomes. METHODS A retrospective single-center study was performed. Patients with soft tissue sarcoma surgically treated in 2005-2019 were included in this study. A total of 120 patients consisting of planned excision (PE) group (n = 88), and unplanned excision (UE) group (n = 32) were included. Overall-survival (OS), local recurrence-free survival (LRFS), metastasis-free survival (MFS), disease-free survival (DFS), incidence rate of reconstructive surgery and musculoskeletal tumor society (MSTS) score were assessed. Propensity score matching method was used in statistical analysis. RESULTS The 5-year survival rate of OS, LRFS, MFS, and DFS did not differ between the PE and UE groups, however, rates of reconstructive surgery were higher in the UE group (PE: 48% vs. UE: 84%, p < 0.001). These results did not differ (PE: 41% vs. UE: 82%, p = 0.012) after propensity score matching was performed to align the backgrounds with difference in tumor size and depth. For MSTS score, the total score and "pain" and "emotional acceptance" scores were higher in the PE group before propensity score matching. The "pain" and "emotional acceptance" scores were higher in the PE group after propensity score matching also. CONCLUSIONS Unplanned excision did not deteriorate oncological outcomes, however unplanned excision lead to unnecessary reconstructive surgery. Unplanned excision adversely affected patient-reported outcomes without worsening pure functional outcomes.

Abstract
BACKGROUND This study aimed to elucidate the clinical outcomes of patients with small (≤5 cm) high-grade soft tissue sarcoma, who underwent unplanned excision with positive surgical margin, using data from the Bone and Soft Tissue Tumor registry in Japan. METHODS We examined 174 patients (101 males and 73 females; mean age, 59 years) with primary non-metastatic soft tissue sarcoma. The tumor size was ≤5 cm, and tumor histological grade was high in all patients. The mean follow-up duration was 50 months. RESULTS Unplanned excision with R1 and R2 margins was reported in 115 (66%) and 59 patients (34%), respectively. After unplanned excision, immediate additional excision was performed in 154 patients, whereas no additional excision was performed in the remaining 20. Of the 154 patients who underwent additional excision, wide surgical margin resection was achieved in 140 patients, while marginal and intralesional resections were achieved in 10 and 3 patients, respectively. Additionally, 93 patients (60%) underwent reconstruction after additional excision. During the last follow-up, 8 patients died of the disease, 22 developed distant metastasis, and 14 reported local recurrence. The 5-year disease-specific survival rate and 5-year metastasis-free survival rate was 93.5% and 85%, respectively. Tumor depth and additional excision after unplanned excision showed statistical significance in the multivariate analysis. The 5-year metastasis-free survival rate was 89.1% in patients with additional excision and 39.2% in those without. Univariate analysis showed an association between additional excision and local control. The 5-year local recurrence-free survival was significantly worse in patients without additional excision after unplanned excision (52.6%) than in those with additional excision (92.8%). CONCLUSION If unplanned excision is performed in patients with small high-grade soft tissue sarcoma, additional excision is recommended for preventing metastasis, along with necessary preparations for reconstruction.

Abstract
BACKGROUND Owing to its rarity, dermatofibrosarcoma protuberance (DFSP) is often inappropriately excised. After unplanned excision (UE), additional excision is commonly performed. We aimed to elucidate the effect of additional excision after UE. PATIENTS AND METHODS We examined 306 patients with primary DFSP. We analyzed surgical outcomes in 291 patients who received planned excision (PE) or additional excision after UE. RESULTS Of 306 patients, 194 received PE and the remaining 112 received UE. Of 112 patients, 97 received additional excision after UE. Additional surgery due to complications was more frequent in patients with UE than in those with PE. The 5-year local recurrence-free rate in patients without additional excision after UE was significantly worse than that in those with additional excision after UE. CONCLUSION If UE is performed, we recommend additional excision for preventing local recurrence; however, the surgical wound should be carefully observed.

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

Abstract
PURPOSE Intramuscular myxoma (IM) is a rare benign myxoid tumor that may be challenging to differentiate from sarcoma in small amounts of biopsied material. Although IM appears to be well-circumscribed macroscopically, it infiltrates the adjacent edematous muscle microscopically. The recommended treatment is resection, but there is controversy with regard to the appropriate surgical margin. This study aimed to clarify which surgical procedure that should be applied when the preoperative diagnosis is IM and how to manage treatment if the postoperative diagnosis turns out to be a sarcoma. METHODS We retrospectively examined 55 IM patients treated from January 1982 to December 2014. Patient characteristics, tumor location, tumor size, radiograph, preoperative and postoperative pathological reports, surgical techniques, treatment outcome, and complications were reviewed. The patients were followed up on for at least 5 years. All patients were confirmed not to have Mazabraud syndrome. RESULTS In the 55 IM patients examined, the mean patient age was 48 years and most were female. The most common tumor locations were in the muscles of the thighs (47%) and buttocks (20%). The mean tumor diameter was 5 cm. Wide resection and marginal resection were performed in 24 and 31 patients, respectively. The mean follow-up duration was 19 years. No local recurrence, malignant transformation, or complications were observed. CONCLUSIONS Marginal resection is suitable in patients whose preoperative diagnosis is IM, as it is able to prevent local recurrence and allows for the preservation of muscle and muscle fascia. If the postoperative diagnosis turns out to be myxoid sarcoma, minimum surgical contamination makes additional wide resection less invasive.

Abstract
Unplanned excision (UE) is defined as a procedure wherein a surgeon operates a tumor resection without appropriate preoperative diagnostic modalities and without the intent to achieve tumor-free margins. Generally, the reconstruction rate after UE is higher than that after planned excision (PE). The present study aimed to investigate how the reconstructive procedure and size of skin defect could be influenced. We reviewed the cases of 442 patients who underwent the resection of soft tissue sarcoma. Patients were stratified into two groups (UE vs. PE). We compared the histologic grade, skin defect, reconstructive procedures, depth of the reconstruction layer. For superficial reconstructions, we also compared procedures involving skin graft-only or flap. 105 cases (23.8%) were UE. Histologic grade in PE was significantly higher (p = .024). The reconstruction rate and size of skin defect in UE was significantly higher (76.2% vs. 27.3%, p < .001) and larger (124.5 cm2 vs. 65.7 cm2, p < .001). The rate of deep layer reconstruction was significantly higher in PE (7.5% vs. 26.1%, p = .001). In superficial reconstructions, 18 (24.3%) skin graft-only procedures were performed in UE and 15 (22.1%) in PE, all other superficial reconstructive procedures involved flap, and there was no significant difference (p = .45). Skin defects were 1.9 times larger after UE than PE. UE did not affect the superficial reconstructive procedure.

Inadvertent excision of lumps which turn out to be sarcomas is not uncommon.Imaging has a limited role in detecting microscopic residual disease but can show the extent of the previous surgical field.Standard treatment is wide re-excision, usually combined with radiotherapy.Residual tumour is found in an average of 50% of reported cases.The presence of residual disease is an adverse prognostic factor.All lumps bigger than a golf ball should have a diagnosis prior to excision.

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 It is not exceptional to come by children with initial unplanned surgical intervention for nonrhabdomyosarcoma soft tissue sarcomas (NRSTS). The aim of this study was to evaluate the presence of residual disease in these patients after re-excision and compare the treatment outcomes with patients who had planned upfront excision. METHODS The data of patients with primary nonmetastatic NRSTS with initially unplanned excision who underwent re-excision between March 2006 and December 2014 were analyzed and the results compared with patients having planned upfront excision in the similar period. RESULTS Of the 84 patients, 40 (48%) had an unplanned excision elsewhere; 35 of these patients had a re-excision. Twenty-one of the remaining 44 patients underwent upfront planned excision. A residual tumor was present in 16 (45.7%) patients. There was no significant difference in the local recurrence, distant metastases, or deaths in patients with re-excision or planned excision. The 5-year overall, disease-free survival and local control rates were, respectively, 93.5%, 90.2% and 96.6% for the re-excision group and 84.9%, 65.2% and 88.5% in the planned excision group (p=NS). CONCLUSIONS The probability of residual disease following unplanned excision of NRSTS is high. The outcomes following re-excision are similar to that with planned excision. PROGNOSIS STUDY Level II evidence.

Abstract
To adequately treat soft tissue tumors, an accurate initial diagnosis is essential. In this article, we describe the notable points during initial diagnoses as outlined by the "Clinical Practice Guideline on the Diagnosis and Treatment of Soft Tissue Tumors". Clinical findings including pain and tumor size, growth speed, and depth, may be important in the diagnosis. In general, malignant soft tissue tumors tend to be larger than 5 cm in size, to occur in deep layers, and grow quickly. However, there are many exceptions. Magnetic resonance images can show characteristics of soft tissue tumors, but most of these are non-specific. The most reliable diagnostic procedure is histological examination. Therefore, a biopsy is mandatory. A core needle biopsy can be performed under local anesthesia at an outpatient clinic without the need for imaging guidance. In cases with deep-seated tumors, an image-guided biopsy is recommended. Incisional biopsies are also widely used procedures. In an incisional biopsy, the skin incision should be parallel to the long axis of the extremities. A meticulous hemostasis must be carried out to prevent post-biopsy hemorrhaging. If adequate hemostasis cannot be achieved, a drain is placed within the incision or at the closest possible site along the incision. Indications for an excisional biopsy are limited to superficial soft tissue tumors, less than 3 cm in size, located at a suitable distance from the nearest vital structure. Furthermore, an excisional biopsy should only be carried out after imaging studies are complete.

Abstract
This study aimed to compare the oncological results between unplanned excision (UE) and planned excision (PE) of malignant soft tissue tumor and to examine the impact of residual tumor (ReT) after UE. Nonmetastatic soft tissue sarcomas surgically treated in 1996-2012 were included in this study. Disease-specific survival (DSS), metastasis-free survival (MFS), and local-recurrence-free survival (LRFS) were stratified according to the tumor location and American Joint Committee on Cancer Classification 7th edition stage. Independent prognostic parameters were identified by Cox proportional hazard models. Two-hundred and ninety PEs and 161 UEs were identified. Significant difference in oncological outcome was observed only for LRFS probability of retroperitoneal sarcomas (5-year LRFS: 33.0% [UE] vs. 71.0% [PE], P = 0.018). Among the 142 UEs of extremity and trunk, ReT in re-excision specimen were found in 75 cases (53%). UEs with ReT had significantly lower survival probabilities and a higher amputation rate than UEs without ReT (5-year DSS: 68.8% vs. 92%, P < 0.001; MFS: 56.1% vs. 90.9%, P < 0.001; LRFS: 75.8% vs. 98.4%, P = <0.001; amputation rate 18.5% vs. 1.8%, P = 0.003). The presence of ReT was an independent poor prognostic predictor for DSS, MFS, and LRFS with hazard ratios of 2.02 (95% confidence interval (CI), 1.25-3.26), 1.62 (95% CI, 1.05-2.51) and 1.94 (95% CI, 1.05-3.59), respectively. Soft tissue sarcomas should be treated in specialized centers and UE should be avoided because of its detrimental effect especially when ReT remains after UE.

Abstract
BACKGROUND We hypothesized that select patients undergoing planned soft tissue sarcoma (STS) excision with anticipated skin and soft tissue deficits could be treated with a two stage surgical procedure which would allow some flexibility in coverage options while not significantly increasing local recurrence rate or wound complication rate. METHODS A retrospective review was undertaken in a series of consecutive patients with a minimum 2-year follow-up treated by a single orthopedic oncologist and a single reconstructive plastic surgeon who were managed with a staged approach STS excision and reconstruction. RESULTS There were 73 patients identified over a ten-year period that underwent staged STS excision and soft tissue reconstruction. There were 12 (16%) initial positive margins resected to negative final margins, and a variety of coverage procedures performed. Wound complication rate was 21%. Local recurrence rate was 11%. CONCLUSION Staged STS excision and reconstruction is an acceptable tool in the armamentarium of the orthopedic oncologist for managing major soft tissue deficits without an increase in local recurrence rates.

Abstract
BACKGROUND Soft tissue sarcomas (STS) are often diagnosed unexpectedly after surgery, and many excisions are incomplete. As histopathological assessments are challenging, patients later referred to comprehensive cancer centers (CCC) often come with an unclear status. This can make treatment planning problematic. We investigated the reliability of primary histopathological assessments, whether revisional surgery improved resection status, and the prognostic value of residual tumor at re-excision. METHODS We analyzed the demographic and clinical characteristics of all patients referred to our CCC between 2003 and 2013. We compared patients treated exclusively at our CCC with those who had primary surgery elsewhere, and focused on resection margins, re-excision type, residual tumor, resection status after re-excision, and oncological outcome. RESULTS Over half (n = 110) of all patients (n = 204) were referred from elsewhere. Seventy-one had undergone an excision without suspicion of malignancy. Resection status in referred patients was significantly inferior to the CCC group (p < 0.0001), although the latter had significantly more serious tumors and advanced disease stages (p < 0.05). The residual tumor rate was 53.13%, with a significantly higher probability in an upper extremity (p = 0.001). Initial histopathological classification was misleading in 46.9% of cases. Re-excision improved resection status in 69% of cases. Residual tumor presumably leads to higher rates of local recurrence (p = 0.057) and significantly shorter times to recurrence (p < 0.05). CONCLUSIONS Re-excision should always follow unplanned STS excisions. Resection margins and histopathological assessments from referring institutions are often unreliable and unsuitable for treatment planning. Residual tumor is a risk factor for earlier and more likely local recurrence.

Abstract
➤ Biopsy, staging, preoperative imaging and planning, as well as surgical treatment of soft-tissue sarcomas, are best carried out in specialized sarcoma centers, with the support of a multidisciplinary tumor board.➤ Tumor bed excision is recommended after most unplanned excisions, with a goal of obtaining complete tumor removal with an appropriately wide margin of resection.➤ The surgical resection area tends to be more extensive during tumor bed excision than during primary resection because of the need to resect potential areas of contamination, resulting in the need for more reconstructive procedures (flaps and skin grafts) and wider radiation fields.➤ Unplanned excisions are associated with an increased rate of local recurrence related to residual disease and positive margins after tumor bed excision, a deep location, and certain histologic subtypes, such as malignant peripheral nerve sheath tumor, myxofibrosarcoma, and dermatofibrosarcoma protuberans.➤ While adjuvant radiation therapy has not been found to mitigate the risk of local recurrence in unplanned excisions, it is generally utilized in the treatment of unplanned excisions as it is in the treatment of primary soft-tissue sarcomas.➤ Given the surgical and oncologic sequelae of unplanned excisions, prevention through the diffusion of concepts by means of provider education on how to approach soft-tissue masses, which can be potential soft-tissue sarcomas, is the best strategy.

Abstract
BACKGROUND Over the past three decades, several studies have reported worse outcomes with unplanned resection for malignant soft tissue tumors. However, the impact of these studies on preventing unnecessary unplanned resection remains unknown. METHODS In a retrospective survey on the treatment of soft tissue sarcomas, we compared cases of unplanned resection with cases of planned resection in terms of the properties of unplanned resection and the oncological and functional outcomes. For the unplanned resection cases, an additional wide resection was performed. RESULTS Of 92 cases, unplanned resection was performed in 24 (26 %). Small or subcutaneous tumors were significantly more frequently subjected to unplanned resection. In 17 of 24 unplanned resection cases, residual tumors (70.8 %) were noted. Plastic surgery was more frequently needed for unplanned resection cases. There was no significant difference between the unplanned resection and control cases with regard to oncological outcome. However, as to local recurrence and overall survival, the events occurred only in the cases with residual tumors in the additional wide resection specimen in the unplanned resection group. There was no significant difference in functional evaluation, except for emotional acceptance, which had a better score in the unplanned resection group. CONCLUSIONS Despite repeated cautions regarding unplanned resection in terms of its inadequate procedure which contradicts the principles of soft tissue sarcoma treatment, unplanned resections are still frequently performed. Perhaps the small size and subcutaneous location of the sarcomas in the unplanned resection group did not evoke the probability of malignancy for the surgeons who initially managed them. Even though an additional wide resection was performed, a residual tumor would lead to a worse outcome. An effective awareness program to avoid unnecessary unplanned resections for soft tissue sarcoma should be considered.

Abstract
BACKGROUND Soft tissue sarcomas are often inappropriately excised without adequate preoperative planning. Inappropriate (unplanned) excisions may adversely affect local recurrence, distant metastasis, patient survival, and /or postoperative function once properly evaluated. QUESTIONS/PURPOSES We asked whether the clinical and treatment characteristics, survival (overall, local recurrence-free, distant metastasis-free), and functional scores of patients with unplanned excisions differ from those with a planned excision. METHODS We retrospectively reviewed 128 patients with planned excisions and 63 patients with unplanned excisions at prereferral hospitals followed by additional reexcisions. We determined whether age, gender, tumor size, depth, histologic grade, operative duration, blood loss, survival, or functional scores differed between the two groups. The minimum followup was 6 months (mean, 55 months; range, 6-275 months). RESULTS The tumor was larger and its location deeper in the planned excision group. Overall, metastasis-free, and local recurrence-free survival were similar in the two groups: 86%, 71%, and 85% in the planned excision group and 96%, 86%, and 92% in the unplanned excision group, respectively. However, additional soft tissue reconstruction was more often necessary for patients with unplanned excisions. No difference in postoperative function was observed. CONCLUSIONS The data suggest an adequate additional wide excision may improve the local control and survival in patients with an unplanned excision as well as the patients with a planned excision. While patients with unplanned excisions had superficial and smaller tumors, survival and postoperative function were similar to those with planned excisions.
