Abstract
In this study, we sought to determine the prognostic value of both the European Organization for Research and Treatment of Cancer-Soft Tissue and Bone Sarcoma Group (EORTC-STBSG) score and the histologic parameters viable tumor, coagulative necrosis, hyalinization/fibrosis, and infarction in patients (n=64) with localized, nonmetastatic high-grade soft-tissue sarcomas after preoperative radiomonotherapy. A standardized macroscopic workup for pretreated surgical specimen including evaluation of a whole section of high-grade soft tissue sarcomas in the largest diameter, was used. Association with overall survival and disease-free survival was assessed. Limb salvage could be accomplished in 98.4% of patients. Overall, 90.6% tumors had negative resection margins. The median postoperative tumor diameter was 9 cm. Undifferentiated pleomorphic sarcoma (42.2%) and myxofibrosarcoma (17.2%) were the most common diagnoses. In all, 9.4% of patients had local recurrence despite clear resection margins, and 50% had distant metastases. Morphologic mapping suggests an overall heterogenous intratumoral response to radiotherapy, with significant differences among histologic subtypes. Complete regression (0% vital tumor cells) was not seen. Categorizing the results according to the proposed EORTC-STBSG 5-tier response score, <1% viable tumor cells were seen in 3.1%, ≥1% to <10% viable tumor cells in 20.4%, ≥10% to <50% viable tumor cells in 35.9% and ≥50% viable tumor cells in 40.6% of cases. Mean values for viable tumor cells were 40% (range: 1% to 100%), coagulative necrosis 5% (0% to 60%), hyalinization/fibrosis 25% (0% to 90%) and infarction 15% (0% to 79%). Hyalinization/fibrosis was a significant independent prognostic factor for overall survival (hazard ratio=4.4; P =0.047), while the other histologic parameters including the EORTC-STBSG score were not prognostic.

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

Abstract
INTRODUCTION Malignant soft tissue tumors are rare tumors representing <1% of all malignancies. As these tumors are rare, it is not uncommon that malignant soft tissue tumor excision is performed without the required preoperative imaging, staging, or wide resection margins for sarcomas. The purpose of this study was to investigate the characteristics of patients with undergoing unplanned excisions. Risk factors for tumor recurrence and mortality in patients treated with unplanned excisions were also analyzed. METHODS Forty-nine patients who underwent unplanned excision at other hospitals and additional wide excision at our hospital between January 2002 and December 2018 were identified. Among them, 42 patients with follow-up for more than 1 year were included in this retrospective study. The relationships between sex, age, tumor depth, histological grade, location, size, surgical margin at additional wide excision, residual tumor, reconstruction, kind of hospital where the primary excision was done (sarcoma vs non-sarcoma center), preoperative examination, chemotherapy, radiation therapy, and oncological outcomes were statistically analyzed. RESULTS Mean patient age was 57.3 years (15-85 years) and the mean observation period was 72.5 months (14-181 months). This analysis showed 53.8% tumors that underwent unplanned excisions were small (<5 cm) and 70.7% tumors were superficial. Multivariate analysis revealed that a positive margin during additional wide excision was significantly associated with a lower 5-year LRFS (p < 0.01). CONCLUSION Most of the tumors underwent unplanned excisions were small (<5 cm) and superficial. Surgeons should be aware that a positive margin during additional wide excision is an independent risk factor for local recurrence.

Effect of Neoadjuvant Therapies on Soft Tissue Sarcomas with Tail-like Lesions: A Multicenter Retrospective Study. Cancers (Basel) 2021; 13:cancers13153901. [PMID: 34359802 PMCID: PMC8345724 DOI: 10.3390/cancers13153901] [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: 07/01/2021] [Revised: 07/27/2021] [Accepted: 07/28/2021] [Indexed: 11/17/2022] Open
Abstract
Simple Summary It is essential to focus on the tumor invasive front (tail-like lesion)—the soft tissue sarcoma’s specific peripheral infiltrative growth characteristics—to avoid leaving unexpected tumor residues during surgery. This study aimed to analyze the effect of neoadjuvant therapy for highly malignant soft tissue tumors with tail-like lesions. From 2012 to 2019, 36 patients were treated with neoadjuvant therapy, including chemotherapy, radiotherapy, or both. Consequently, we observed shrinkage, and occasionally the disappearance of the tail-like lesion. The lesion’s regression was related to the necrosis rate of the main part of the tumor. However, the regression of lesions was not directly related to the achievement of surgery with a microscopically negative margin or improvements of oncological outcomes. Thus, a more multi-angle evaluation to elaborate surgical strategy is necessary. Abstract Several types of soft tissue sarcomas have peripheral infiltrative growth characteristics called tail-like lesions. The efficacy of neoadjuvant therapy for tumors with tail-like lesions has not been elucidated. From 2012 to 2019, we analyzed 36 patients with soft tissue sarcoma with tail-like lesions treated with neoadjuvant therapy, including chemotherapy, radiotherapy, or both. The effect of neoadjuvant therapy on the tail sign was investigated by analyzing the change in tail-like lesions during neoadjuvant therapy and histological responses. The median length of the tail-like lesion reduced from 29.5 mm at initiation to 19.5 mm after neoadjuvant therapy. The extent of shrinkage in tail-like lesions was related to the histopathological responses in the main part of the tumor. Complete disappearance of the tail-like lesion was observed in 12 patients; however, it was not related to achieving a microscopically negative margin. The oncologic outcomes did not significantly differ between cases with and without the complete disappearance of tail-like lesions. This study indicated that the shrinkage of tail-like lesions did not have a significant effect on complete resection or improvements of clinical outcomes. A more comprehensive evaluation is needed to elaborate on the surgical strategy.

Abstract
Myxofibrosarcoma is one of the most common soft tissue sarcomas in the elderly. It is characterized by an extremely high rate of local recurrence, higher than other soft tissue tumors, and a relatively low risk of distant metastases.Magnetic resonance imaging (MRI) is the imaging modality of choice for the assessment of myxofibrosarcoma, which plays a key role in the preoperative setting of these patients. MRI features associated with the high risk of local recurrence are: high myxoid matrix content (water-like appearance of the lesions), high grade of contrast enhancement and presence of an infiltrative pattern ("tail sign"). On the other hand, MRI features associated with worse sarcoma specific survival are: large size of the lesion, deep location, high grade of contrast enhancement. Recognizing the above-mentioned imaging features of myxofibrosarcoma may be helpful in stratifying the risk for local recurrence and disease-specific survival. Moreover, the surgical planning should be adjusted according to the MRI features.

Abstract
Cutaneous mesenchymal tumors (CMT) are rare tumors with wide clinicopathologic heterogeneity. Treatment of malignant cutaneous mesenchymal tumors traditionally includes wide local excision (WLE), though Mohs micrographic surgery (MMS) has been increasingly used. A PubMed literature review of articles from inception until September 2019 related to malignant CMT and surgical treatment with MMS or WLE was completed. Dermatofibrosarcoma protuberans treated with MMS recurred in 1.2% of patients with no reported metastasis. Atypical fibroxanthoma treated with MMS recurred and metastasized in 2.7 and 2.5%, respectively. Undifferentiated pleomorphic sarcoma treated with MMS recurred in 32% with an unknown metastatic rate. Superficial leiomyosarcoma treated with MMS recurred in 3.8% with no reported metastasis. Cutaneous angiosarcoma and myofibrosarcoma treated with MMS have shown no recurrence or metastatic disease, but literature is sparse. The rarity of malignant CMT and the lack of comparative data on treatment make conclusive treatment recommendations difficult. However, recent literature suggests MMS is a useful option and potentially a superior treatment for primary cutaneous mesenchymal tumors.

Abstract
AIMS The existing clinical guidelines do not describe a clear indication for adjuvant radiotherapy (RT) in the treatment of superficial soft tissue sarcomas (STSs). We aimed to determine the efficacy of adjuvant RT for superficial STSs. METHODS We retrospectively studied 304 patients with superficial STS of the limbs and trunk who underwent surgical resection at a tertiary sarcoma centre. The efficacy of RT was investigated according to the tumour size and grade: group 1, ≤ 5 cm, low grade; group 2, ≤ 5cm, high grade; group 3, > 5 cm, low grade; group 4, > 5 cm, high grade. RESULTS The five- and ten-year local recurrence-free survival (LRFS) for all patients was 88% and 81%, respectively. While the efficacy of adjuvant RT was not proven in local control of all patients (five-year LRFS; RT+, 90% versus RT-, 83%; p = 0.074), the LRFS was significantly improved by adjuvant RT in group 2 (five-year LRFS; RT+, 96% versus RT-, 82%; p = 0.019), and group 4 (five-year LRFS; RT+, 87% versus RT-, 73%; p = 0.027). In groups 2 and 4, adjuvant RT significantly reduced the LR risk if the resection margin was clear but less than 5 mm; the LR rate was 7% with adjuvant RT compared with 26% with surgery alone (p = 0.003). There was no statistical relationship with the use of adjuvant RT and survival in every group. CONCLUSION Adjuvant RT reduces the risk of local recurrence in patients with superficial high-grade STS regardless of tumour size, especially when resection margin is less than 5 mm.

Abstract
BACKGROUND An infiltrating abnormal signal around soft-tissue tumors along the fascial, neurovascular, or musculature plane on magnetic resonance imaging (T2-weighted, gadolinium-enhanced T1-weighted, or short-tau inversion recovery) is recognized as the "tail-like pattern". The tail-like pattern was intensively analyzed in myxofibrosarcoma, but not in other sarcomas. We aimed to answer some key questions about the tail-like pattern such as its incidence and effect on oncological outcomes. METHODS The presence of the tail-like pattern in 114 soft-tissue sarcomas was evaluated on T2-weighted images or gadolinium-enhanced T1-weighted images, or both. We analyzed the incidence of the tail-like pattern in all cases and in specific histological subtypes. We also assessed the clinical backgrounds of the presence of the tail-like pattern and its impact on achieving adequate surgical margins and oncological outcomes, including local recurrence and overall survival. RESULTS The tail-like pattern was detected in 50% of cases. The tail-like pattern was most common in myxofibrosarcoma and undifferentiated pleomorphic sarcoma, and less common in low-grade sarcomas. Trans-compartmental invasion of the tumor and high-grade malignancy were common clinical backgrounds for the presence of the tail-like pattern. The presence of the tail-like pattern significantly inhibits the achievement of preoperatively planned surgical margins despite planning the margins outside the tail-like pattern area. The tail-like pattern was an independent risk factor for local recurrence. The pattern was not an independent risk factor for worse overall survival, although it was a risk factor in univariate analysis. CONCLUSION The tail-like pattern is clinically significant in myxofibrosarcomas and other sarcomas with respect to the preoperative evaluation of malignancy by magnetic resonance imaging, and negatively affects successful resection and oncological outcomes. A more sophisticated modality for the evaluation and clinical management of the tail-like pattern is needed in the future.

Abstract
Myxofibrosarcoma (MFS) and undifferentiated pleomorphic sarcoma (UPS) frequently display infiltrative growth into the adjacent normal soft tissue. In this study, we aimed to determine whether the microscopic extension into surrounding normal tissue can influence the local recurrence of MFS and UPS. A total of 42 cases (22 MFS and 20 UPS) were examined. The length of the microscopic extension was measured from the edge of the main tumor mass to the end of infiltration. The length of 5.5 mm was selected as the optimal cut-off value that could predict local recurrence using the receiver operating characteristic (ROC) curve and Youden index. Longer length of microscopic extension was significantly correlated with the status of resection margin (P = 0.032). The group with longer length of microscopic extension (>5.5 mm) had significantly worse recurrence-free survival than the group with shorter length of microscopic extension (≤5.5 mm) (P = 0.000). Multivariate analysis revealed that the length of microscopic extension was independent predictors of recurrence-free survival (P = 0.018). In conclusion, microscopic extensions at the edge of the main mass into the surrounding normal tissue were observed in most MFS and UPS patients, and the length of microscopic extension was associated with local recurrence.

Abstract
Superficial solid masses are common conditions in clinical practice, however, some of which can be easily diagnosed and others would be difficult. Although imaging of superficial masses is not always characteristic, it would be helpful to give a definitive diagnosis or narrow a differential diagnosis. Crossing-section imaging can depicture the masses directly, find some pathognomonic signs and demonstrate their relationship with adjacent structures, which can provide decision support for clinician's reference. Computed tomography (CT) can be used to detect calcifications and bone erosion which could not be seen on radiographs. Magnetic resonance imaging (MRI) is the preferred way for evaluating soft tissue lesions and provides information on hemorrhage, necrosis, edema, cystic and myxoid degeneration, and fibrosis. Other advantages of MRI are its superior soft tissue resolution and any profile imaging, which can aid the assessment of extension and adjacent infiltration. Positron emission tomography (PET)/CT and PET/MRI have been increasingly used in bone and soft tissue sarcomas and provides advantages in the initial tumor staging, tumor grading, therapy assessment, and recurrence detection. Therefore, imaging examination can play an important role in treatment decision making for superficial solid tumors. Here we review the important conditions presenting as superficial mass and show the imaging of typical cases diagnosed in our hospital.

Abstract
BACKGROUND Soft tissue sarcomas are challenging to oncologists due to their unique character, the infrequency of their occurrence, and the difficulties in predicting outcomes. Advances in imaging, as well as improvements in surgical techniques and adjunctive treatment methods, have improved care for patients with these unusual disorders. METHODS The various types of soft tissue tumors are defined, and the statistics for the Orthopaedic Oncology Group in relation to them are reviewed and compared with literature references. RESULTS The overall survival rate for 1,220 tumors treated at our institute from June 1972 to June of 2001 was 72%, with a wide range. Patients with leiomyosarcomas, clear cell sarcomas, and malignant fibrous histiocytomas had a poorer survival rate, while those with fibrosarcomas, liposarcomas, and neurofibrosarcomas fared better. Outcome was affected by patient age, tumor anatomic site, tumor stage, and a history of recurrence. CONCLUSIONS Competent imaging, predictive immunological and genetic studies, improved surgery, and newer methods of adjunctive and neoadjunctive treatment should result in improvements in outcomes for patients with these tumors.

Abstract
Primary intracranial myxofibrosarcoma is exceedingly rare, with less than 10 cases published. We present a case of a 23-year-old man with previous history of a primary low grade myxofibrosarcoma of the left parietal-occipital convexity resected in March 1999. He subsequently underwent several interventions for multiple local recurrent disease until March 2004. At that time, complete remission was documented. About 8 years later, in February 2012, the patient was admitted to the emergency room with refractory acute pulmonary oedema. On work up, sustained monomorphic ventricular tachycardia and hyperechoic myocardial mass with invasion of the right ventricular cavity were detected. Electrical cardioversion was unsuccessful and irreversible cardiac arrest followed. The autopsy confirmed multiple bilateral lung metastases, malignant pulmonary embolism and myocardial invasion by the primary tumour, with intracavitary cardiac thrombosis and absence of intracranial disease. To the best of our knowledge, this is the first report of extracranial metastases of this neoplasm.

Abstract
BACKGROUND Myxofibrosarcoma (MFS) arises most commonly in the proximal extremities of the elderly, where it may involve subcutaneous and dermal tissues and masquerade as benign entities in limited biopsy samples. We encountered such a case, in which positivity for CD34 and morphologic features were initially wrongly interpreted as a 'low-fat/fat-free' spindle cell/pleomorphic lipoma. Case series have not assessed prevalence of CD34 reactivity among cutaneous examples of MFS. METHODS We performed a systematic review of our institution's experience, selecting from among unequivocal MFS resection specimens those superficial cases in which a limited biopsy sample might prove difficult to interpret. These cases were immunostained for CD34 and tabulated for clinicopathologic characteristics. RESULTS After review of all MFS diagnoses over 5 years (n = 56), we identified a study group of superficial MFS for comparison to the index case (total n = 8). Of these, the index and three additional cases (4 of 8, 50%; 2 low, 2 high grade) demonstrated positive staining for CD34, with diffuse staining of spindled cells including cellular processes. Four additional cases showed no or equivocal/rare staining. CONCLUSIONS CD34 positivity should be recognized as prevalent among such cases and should not be inappropriately construed as inveighing against a diagnosis of MFS in favor of benign entities.

Abstract
BACKGROUND Atypical fibroxanthoma (AFX) and undifferentiated pleomorphic sarcoma (UPS) are uncommon, spindle cell cutaneous malignancies. Solid organ transplant recipients (SOTRs) are immunosuppressed and therefore have a higher incidence of cutaneous malignancies. OBJECTIVE We describe the clinical spectrum of AFX and a more-aggressive, deeper variant, UPS, in SOTRs. MATERIALS AND METHODS A retrospective chart review of AFX and UPS in SOTRs was implemented. Cases from Vanderbilt University, Emory University, Mayo Clinic-Jacksonville, and University of Rochester were included. A literature search included previously published cases. RESULTS The average age of SOTRs at time of tumor presentation was younger than typically seen in immunocompetent patients for AFX. Rates of local recurrences and metastases were higher in the SOTRs than is noted in the immunocompetent literature. Rates of recurrence were higher in those treated with excision than in those treated with Mohs micrographic surgery (MMS). CONCLUSION AFX and UPS may have a greater risk for recurrence, metastases, and mortality in SOTRs, in whom early treatment with MMS may demonstrate certain advantages in terms of minimizing risk of recurrence and metastasis. UPS and recurrent tumors should be staged appropriately and may respond to adjuvant radiation therapy and reduction of immunosuppression. Immunohistochemical evaluation is recommended to exclude other spindle cell tumors.

Abstract
BACKGROUND Several variables have been reported as being prognostic with regard to the outcomes of soft-tissue sarcomas. Although the tumors are subjectively ominous, no prior study has been performed to evaluate the treatment or prognosis of fungating soft-tissue sarcomas. METHODS We performed a retrospective review of all soft-tissue sarcomas treated at our institution between 1989 and 2004 that had been followed for a minimum of two years or until the death of the patient. Our study group consisted of twenty-four patients with a primary high-grade fungating tumor, and our control group consisted of 146 consecutive patients with a primary high-grade non-fungating tumor. The study cohorts were compared with regard to disease presentation, treatment, and oncologic outcomes. RESULTS There were no significant differences in tumor size, tumor depth, or histopathologic diagnoses between the cohorts, although the patients with a fungating tumor tended to be older (mean, sixty-five years compared with fifty-five years in the control group; p = 0.004) and have shorter postoperative follow-up (mean, thirty-eight months compared with sixty-five months in the control group; p = 0.03). The proportion of patients presenting with metastases was significantly greater in the group with a fungating tumor (33% compared with 9% in the control group; p = 0.003). Significantly more patients with a fungating tumor underwent amputation (35% compared with 12% in the control group; p = 0.01), while a greater proportion of control patients received radiation therapy (68% compared with 39% in the group with a fungating tumor; p = 0.02). There was no difference in the proportions of patients receiving chemotherapy or in the local recurrence rates between the two cohorts. The Kaplan-Meier five-year overall survival estimates were 20% in the group with a fungating tumor compared with 63% (p < 0.0001) in the control group. The Kaplan-Meier five-year disease-specific survival estimates for patients presenting with localized disease was 58% in the group with a fungating tumor and 74% in the control group (p = 0.05). Multivariate analysis demonstrated that disease stage, fungation, and a tumor size of > or = 10 cm were significant independent negative prognostic factors for disease-specific survival. CONCLUSIONS Malignant tumor ulceration is an independent predictor of a poor prognosis for patients with a high-grade soft-tissue sarcoma. Despite the discouraging overall prognosis, aggressive multidisciplinary treatment can lead to long-term survival in an important subgroup of patients with fungating lesions.

Abstract
Soft tissue tumors are a heterogeneous group of benign and malignant processes. Some are assumed to be reactive; others are clearly neoplastic. Because of their rarity, they frequently pose diagnostic problems for surgical pathologists. Accurate diagnosis of these tumors is enhanced by knowledge of the clinical features of the given lesions and, at times, by application of immunohistochemical and molecular techniques. In this article the lesions are described essentially in accordance with the World Health Organization classification.

Abstract
Myxofibrosarcoma or myxoid malignant fibrous histiocytoma is one of the most common fibroblastic sarcomas in older patients. It is characterized by a tendency for predominantly subcutaneous, multinodular, diffusely infiltrative growth, which may extend to the overlying dermis and present as a cutaneous lesion. Histologically, it comprises a spectrum ranging from hypocellular low-grade myxoid to high-grade pleomorphic sarcoma. Because the dermal presentation usually appears relatively banal, accurate diagnosis is sometimes challenging. In this report, we present two cases of myxofibrosarcoma with dermal involvement.

Abstract
Myxofibrosarcoma (myxoid malignant fibrous histiocytoma) is one of the most common fibroblastic sarcomas in the older patient, where it can sometimes present with anatomically deceptive boundaries. Myxofibrosarcoma is now fully characterized as a distinctive and definable pathologic entity. Clinically there is a tendency for predominantly subcutaneous, multinodular, diffusely infiltrative growth, which may extend to the overlying dermis and present as a cutaneous lesion. Histologically myxofibrosarcoma comprises a spectrum ranging from hypocellular low-grade myxoid to high-grade pleomorphic sarcoma. We report herein 6 cases of myxofibrosarcoma each with dermatological presentation as a cutaneous nodule. The dermal component in each of the lesions was low- to intermediate-grade and predominantly myxoid resulting in confusion with benign myxoid neoplasms in small biopsy specimens. The purpose of this series is to focus the attention of workers in dermatology on a subject rarely discussed in dermatopathology literature: the cutaneous presentation of myxofibrosarcoma and the potential for clinical and histologic misinterpretation, as benign dermal lesions.
