Abstract
The aim of this study was to evaluate the outcome of patients with soft tissue sarcoma of the extremity and abdominal wall. This is the retrospective analysis of patients from a prospectively maintained data base from a single institute. We identified 79 patients with intermediate- to high-grade soft tissue sarcomas who were treated at our institute between Jan 2015 and July 2018. Low-grade tumors were excluded. There were 60 males and 19 females with a mean age of 44.6 years. Of the 79 sarcomas, 50 were in the lower limb and 24 in the upper limb and 5 were in abdominal wall. The commonest subtypes were undifferentiated pleomorphic sarcoma (n = 21) and synovial sarcoma (n = 19). Only 9 patients had metastatic disease at presentation. All 79 patients underwent surgical resection with an intent to achieve clear margins. Amputation was done in 19 patients while wide excision of the tumor was done in 60 patients. Adjuvant radiotherapy was given in 49 patients while adjuvant chemotherapy was given in 35 patients. At last follow-up (73 patients), 48 patients are alive without disease, 9 are alive with disease, 12 patients had died of disease, and 4 patients died due to other causes. Overall survival (OS) for 3 year is 77.6%, and estimated mean survival is 55.05 months. Relapse-free surviva (RFS)l at 3 year is 74.3%, and estimated mean RFS is 51.78. The only independent factor that affected the OS was the dimension of primary tumor (p = 0.02). For disease-free survival, the independent factors that affected outcome were stage at presentation (p = 0.04) and dimension of the tumor (p = 0.04). Short-term results shown by this study shows good outcome in patient with intermediate- to high-grade sarcomas when multidisciplinary approach is utilized for the management. Patients who had metastatic disease at presentation did worse than patients who did not.

Abstract
Objective: To assess the prognostic factors and results of limb sparing surgery and postoperative radiotherapy (PORT) in patients with non-metastatic soft tissue sarcomas (STS) of the extremities. Methods: Between 1980-2007, 114 extremity-located STS treated with PORT were analyzed retrospectively. Tumors were mostly localized in the lower extremities (71,9%). The median radiotherapy (RT) dose was 60.9 Gy. Chemotherapy was administered to 37.7% of the patients. Tumor sizes were between 3-26 cm (median 7 cm). The three most frequent histological types included undifferentiated pleomorphic sarcoma (26.3%), liposarcoma (25.4%), and synovial sarcoma (13.2%). The median follow-up for all patients was 60 months, and 81 months for survivors. Results: The 5- and 10-year local control (LC) rates were 77% and 70.4%, respectively; actuarial survival rates for 5 and 10 years were 71.8% and 69.1%, respectively. Increasing the dose above 60 Gy for all patients and the patients with positive margins demonstrated a clear benefit on 5-year LC (p=0.03 and p=0.04, respectively). Based on multivariate analysis, the addition of chemotherapy and RT dose were independent prognostic factors for LC. A recurrent presentation significantly affects the disease-free survival. Conclusions: PORT for STS of the extremities provides good long-term disease control with acceptable toxicity in a multidisciplinary approach. Level of evidence III, Retrospective study.

Abstract
BACKGROUND While survival after surgical treatment of extremity soft tissue sarcoma (STS) is traditionally reported as actuarial survival, conditional survival (CS) may be more clinically relevant as it accounts for time already survived. We compared actuarial survival and CS of STS patients. MATERIALS AND METHODS We analyzed 567 patients who underwent surgery for localized extremity STS. Actuarial survival was estimated using the Kaplan-Meier method. Cox proportional hazards model was used to evaluate factors associated with disease-specific survival. Five-year CS (CS5) estimates at "χ" year(s) after surgery were calculated as CS5 = S(χ + 5)/S(χ). RESULTS Whereas actuarial survival decreased over time, CS5 increased. The postsurgical 1-, 3-, and 5-year CS5 values were 84.5%, 90.0%, and 93.8%, respectively, whereas the 6-, 8-, and 10-year actuarial survival rates were 82.0%, 79.4%, and 78.5%, respectively. The calculated CS5 exceeded actuarial survival especially in patients with risk factors such as large tumor size and Federation Nationale des Centers de Lutte Contre le Cancer (FNCLCC) grades 2 and 3 tumors. Patients with tumor size ≥5 cm had an actuarial survival of 73.9% at 10 years compared to a CS5 of 95.4% in patients alive at 5 years. Likewise, patients with FNCLCC grade 3 tumors had an actuarial survival of 71.1% at 10 years compared to a CS5 of 96.0% in patients alive at 5 years. CONCLUSIONS Survival estimation by determination of CS can be dynamic and accurate especially in high-risk patients. CS can be useful for survival prediction and clinical decision making in extremity STS patients.

Abstract
BACKGROUND There are very few published data on the management of primary intrathoracic sarcoma, defined as sarcomas arising from the lung, pleura, and mediastinum, excluding the chest wall. Therefore, the aim of this study was to evaluate the outcome of patients with intrathoracic sarcoma treated at an academic referral center over a 21-year period. METHODS A retrospective search was performed to identify patients with intrathoracic sarcomas treated with surgical resection from January 1990 to November 2011 at the University of Washington Medical Center. Local control and overall survival were analyzed in relation to the treatment received. RESULTS Thirty-five patients were identified. Hazard ratios for local control, adjusted for tumor margin status, at 5 years were 0.74 (95 % CI [0.21, 2.58]) for the addition of chemotherapy (CT) to surgery, 0.57 (95 % CI [0.15, 2.23]) with the addition of (radiation therapy) RT, and 0.50 (95 % CI [0.06, 4.03]) with the addition of both CT and RT. At 7 years, the ratios for local control were 0.69 (95 % CI [0.20, 2.36]) for CT added to surgery, 0.58 (95 % CI [0.15, 2.27]) for RT, and 0.41 (95 % CI [0.05, 3.33]) with the addition of both CT and RT. Hazard ratios for overall survival, adjusted for sarcoma stage, at 5 years were 0.61 (95 % CI [0.16, 2.39]) for the addition of CT to surgery, 1.03 (95 % CI [0.26, 4.08]) for the addition of RT, and 0.54 (95 % CI [0.11, 2.69]) for the addition of both CT and RT. The 7-year hazard ratios for overall survival were 0.77 (95 % CI [0.23, 2.60]) for CT added to surgery, 0.99 (95 % CI [0.25, 3.84]) for the addition of RT, and 0.42 (95 % CI [0.09, 2.05]) for both CT and RT with surgery. At 10 years, hazard ratios for overall survival were 0.71 (95 % CI [0.21, 2.38]) for added CT, 0.81 (95 % CI [0.21, 3.08]) for added RT, and 0.33 (95 % CI [0.07, 1.65]) for the addition of both CT and RT to surgery. CONCLUSIONS Our series is the largest published study of intrathoracic sarcoma which focuses on the survival benefit of adding RT, chemotherapy or both to surgery in resectable intrathoracic sarcoma. Our data suggest a potential benefit in local control and survival from adjuvant therapy, with the greatest benefit likely to come from combined CT and RT, though none of the results achieved statistical significance. As intrathoracic sarcomas are rare and histologically heterogeneous, larger collaborative studies are necessary to determine treatment efficacy and elucidate which histologic subtypes are likely to benefit most from adjuvant therapy.

Abstract
BACKGROUND Mesenchymal malignancies of salivary origin are rare and are histologically diverse. We reviewed our experience with these tumors, as well as the published literature, with an emphasis on treatment modalities and prognosis. METHODS We identified 17 patients treated for malignant mesenchymal cell tumors at The University of Texas MD Anderson Cancer Center between 1990 and 2007. We compared our results to the literature from January 1990 to July 2010. RESULTS Tumors were located primarily in the parotid gland and were primarily T1 tumors (<5 cm). All patients were treated with surgical resection, and 13 patients were given adjuvant therapy. Seven patients (41%) had recurrence, and 4 developed distant metastases. The overall 5-year and 10-year survival rates were 42% and 20%, respectively. CONCLUSIONS Our case series and literature review show that sarcomas of the salivary glands have a high rate of recurrence and are associated with a poor prognosis.

Abstract
Purpose. To evaluate the outcome after resection of malignant chest wall sarcoma, requiring reconstruction of the chest wall. Subjects. Twenty-two patients, 15 with primary tumours, were operated on in our institution between 1983 and 1996. Four patients underwent surgery after a previous intralesional or marginal excision and three patients because of a local recurrence. Methods. The tumour was resected ‘en bloc’, including skin, muscle and thoracic skeleton. When necessary, adjacent organs invaded by the tumour, such as lung, pericardium and diaphragm, were also removed to obtain a wide margin. Reconstruction of the chest wall was performed with Marlex mesh (n=9), methylmethacrylate cement (n=2) or a Marlex methylmethacrylate ‘sandwich’ (n=11). Results. The median tumour size was 9.5 (2–20) cm. The most common type of tumour was chondrosarcoma (12 cases). No patient died in hospital. Five patients required reoperation because of complications, two patients because of loosening of the acrylate prosthesis, two because of necrosis of soft tissue coverage and one was reoperated because of bleeding. Four patients died of generalized tumour disease between 5 and 77 months after surgery and one patient died of a local recurrence 32 months after the primary operation. Seventeen patients are alive, with a median follow-up of 36 (4–162) months. Microscopic radicality (negative margin) was achieved in 17 patients but 5 of these had local recurrences. Two of five patients with positive margins had a local recurrence of the tumour. Of the seven patients with local recurrences, two also developed metastases. Discussion. Large chest wall sarcomas can be successfully resected and the chest wall reconstructed with low morbidity and mortality.

Abstract
Adult soft tissue sarcoma of the head and neck are rare and represent a heterogeneous group of tumours of different histological variants. Management of these neoplasms presents a great challenge. Malignant fibrous histiocytoma, fibrosarcoma, angiosarcoma and malignant peripheral nerve sheath tumour are the most frequently found sarcoma types in the head and neck. Although traditional morphological assessment is the foundation of clinical decision making, the role of immunohistochemistry and molecular biology are useful for diagnosis, prognosis and identification of possible targets for molecular therapy. The most frequently involved tumour sites are scalp/face, sinonasal tract/anterior skull base and parotid/neck. The management of soft tissue sarcomas in the head and neck is primarily surgical. Since it is difficult to obtain wide margins during surgical treatment in head and neck sarcomas, because of anatomic constraints, most patients undergo post-operative irradiation. Survival varies from 50 to 80%. Prognostic factors are tumour grade, margin status and tumour size. With further insight into the biology of soft tissue sarcoma, modern imaging techniques and new treatment options, we will most certainly be able to improve clinical outcome in patients with soft tissue sarcoma in the upcoming years.

Abstract
BACKGROUND Single-institutional studies lack sufficient power to assess the role of surgery and radiotherapy in the management of sarcomas involving the anterior skull base. For this study, an international collaborative study group analyzed a large cohort of patients who underwent surgery for the treatment of skull base tumors. METHODS A subset of 146 patients who had a histologic diagnosis of skull base sarcoma (SBS) formed the basis of this report. Most patients were aged > or =21 years (77%) and had stage IV disease (56%). Adjuvant radiotherapy was received by 35% of patients, and chemotherapy was received by 10% of patients. RESULTS Orbital involvement was encountered in 53% of patients, involvement of the orbital wall was encountered in 46% of patients, and intracranial extension was encountered in 28% of patients. Positive microscopic margins were reported in 43% of patients (51 of 118 patients). Treatment-related complications were reported in 27% of patients, and postoperative mortality was reported in 1.4% of patients. With a median follow-up of 34 months, the 5-year overall, disease-specific, and recurrence-free survival rates were 62%, 64%, and 57%, respectively. Tumor grade and adjuvant radiotherapy were not significant predictors of survival. Prior radiotherapy, intraorbital extension, positive margins, and postoperative complications were significant predictors of reduced disease-specific survival on univariate analysis. The presence of positive/close margins, however, was the only independent predictor of poor overall, recurrence-free, and disease-specific survival on multivariate analysis (relative risk, 2.4; P = .006). The 5-year disease-specific survival rate was 77%, 43%, and 36% for patients with negative, close, and positive margins, respectively. CONCLUSIONS The current results indicated that wide craniofacial resection with negative margins is an independent prognostic predictor of better outcome. Patients with positive margins have a high risk for tumor recurrence independent of tumor grade.

Abstract
Soft tissue sarcomas (STS) are particularly rare malignancies that constitute less than 1% of all malignancies. In recent years, prognostic clinical factors have been defined that help to stratify patients regarding their risk for local and distant recurrence and death from disease. Tumor grade, size, depth, completeness of resection, and presentation status are among the independent prognostic factors. At present, the treatment of these tumors constitutes a wide or marginal excision, adequate primary reconstruction, and radiotherapy. Surgery has generally been recommended as the primary method of treatment for achieving local control. Modern reconstructive surgery, especially musculocutaneous, either pedicle or free flaps, has made more extensive resections possible, while providing acceptable cosmetic and functional results. This study deals with our experience in the treatment of resectable STS with selective combination of treatment modalities.

Abstract
Recent publications have permitted to quantify the benefit of radiotherapy in the conservative treatment of soft tissue sarcoma of the limbs. The aim of this review is to focus on aspects of radiotherapy witch influence local control and functional outcome for early and late normal tissue damage. The evaluation of late effects is performed according to Soma-Lent (Subjective-Objective-Management-Analytic-Late Effects of Normal Tissues) classification. About complications, neurological complications are probably under estimated and are related to total dose of radiation therapy.

Abstract
PURPOSE To evaluate retrospectively the anatomical definition of target volumes in the treatment of soft tissue sarcomas of the limbs and to study the radiation dose in the local control and toxicity. METHODS AND PATIENTS Seventy-seven patients were consecutively treated for primary soft tissue sarcoma of the extremity with limb sparing surgery and external beam radiotherapy (EBRT) in the same institution. The median follow up was 56 months (17-89 months). RESULTS Fifty-two patients (67%) had clear microscopic surgical margin (R0 resection), 23 (30%) had histologically positive microscopic margin (R1 resection), 2 had a macroscopic residual disease (R2 resection). An anatomical definition of target volumes has been realised. The mean dose was 50 Gy in 25 or 28 fractions; 23 patients received a boost restricted to the tumor bed: 13 with EBRT, 10 with brachytherapy (BRT). Thirty-four patients had an adjuvant chemotherapy. The overall 5 year local relapse rate was 10%. Seven local relapses were described, five of the high-grade tumours, and five in patients with positive margin. In univariate analysis, quality of surgery shows a significant effect for local control. By using LENT-SOMA scale for late toxicity, a significant difference was found for neurological complications for patients receiving a boost. CONCLUSIONS The results of the series validate the concept of anatomical definition of the initial target volume. A boost should be realised for positive margin tumors and may be for high-grade tumors. Neurological toxicity must be considered for the evaluation of the prescribed dose.

Abstract
Soft tissue sarcomas (STS) are a rare and heterogeneous group of malignancies that most commonly present as large painless masses deep in the muscular compartments of the extremities. Investigation and treatment of these patients must be undertaken at a tertiary referral unit. Staging studies must include a high-quality magnetic resonance imaging (MRI) scan of the local site and a computed tomography (CT) scan of the chest to investigate for possible metastatic disease. Review of biopsy material must be undertaken by an experienced musculoskeletal pathologist. Currently, histologic diagnosis and grade are assigned to the tumor, but in tumors such as synovial sarcoma and Ewing's family of tumors, molecular evaluation is becoming crucial for diagnostic, prognostic, and therapeutic reasons. Surgical resection of sarcomas with negative surgical margins remains the mainstay of treatment. Surgical treatment alone is indicated for small superficial masses that are not adjacent to bone or neurovascular structures. However, in large deep masses where surgical margins are likely to be close in order to preserve important neurovascular structures and bone, combined treatment using surgical resection and radiation results in acceptable local control rates and reasonable patient function. It is incumbent on the management team to decide on timing of radiotherapy as a practice. This decision is based on several factors but potential complications must be taken into account. In this regard the long-term effects on normal tissues must be considered. Functional outcome has become an essential consideration when recommending treatment. If promising techniques become available to reduce the incidence of wound complications or to decrease the dose of radiation to normal tissue, preoperative radiation should be considered in light of its lower incidence of long-term effects that result in reduction in patient function.

Abstract
PURPOSE OF REVIEW This review discusses the classification, etiology, diagnosis, evaluation, treatment, and prognosis of sarcoma of the head and neck region. RECENT FINDINGS Sarcomas account for less than 1% of all malignancies in the United States with only 5 to 15% of these sarcomas occurring in the head and neck region. However, about 1 in 3 pediatric sarcomas will occur in the head and neck region. Occasionally, these tumors are associated with genetic syndromes or previous radiation exposures, but, most commonly, no clear etiology exists. Pathologic classification is critical to the ultimate treatment and prognosis of sarcoma of the head and neck. Osteosarcoma, rhabdomyosarcoma, malignant fibrous histiocytoma, and angiosarcoma are the most common types of sarcoma to occur in the head and neck region; however, up to 20% of head and neck sarcomas will remain unclassified. Surgery has been central to the management of these malignancies with some exceptions in the pediatric population. Adjuvant chemotherapy is being utilized and/or studied for most high-grade sarcomas and adjuvant radiotherapy is important for disease control in high-grade soft-tissue sarcomas. Prognosis is clearly related to tumor grade and margin status. SUMMARY Sarcomas of the head and neck region are rare malignancies often without a clear etiology. Expert pathologic review and classification is critical, as are quality imaging and multidisciplinary management.

Abstract
With the exception of pediatric RMS, soft tissue sarcomas only rarely arise in the head and neck region. Soft tissue sarcomas include a diverse array of histologic types because of the variety of mesenchymal tissues from which they originate. The combination of infrequent occurrence, varied pathologic features, and the many potential sites of presentation makes these tumors a challenge for the head and neck oncologist and underscore the need for review by a pathologist experienced with soft tissue tumors. Classification schemes that group sarcomas according to grade have been helpful in providing prognostic information. Although local control of the primary tumor is critical to successful treatment of both high- and low-grade lesions, the high rate of distant metastases in high-grade tumors supports the role of combined modality therapy. Compared with other types of head and neck neoplasms, such as squamous cell carcinoma, soft tissue sarcomas have low rates of regional metastases. Surgery generally has been recommended as the primary method of treatment for achieving local control, except in those high-grade tumors arising in sites not amenable to resection. Exceptions to this principle include RMSs of the orbit, paranasal sinuses, and masticator space in children; these are usually treated with radiotherapy and combined multiagent chemotherapy, thereby avoiding the functional and cosmetic impact of surgery. Also, extensive angiosarcomas of the scalp should be treated with multimodality therapy combining surgery and wide-field radiation therapy in an attempt to achieve local control. Adjuvant radiotherapy is generally recommended for high-grade sarcomas, large tumors, close or positive surgical margins, and certain histologic variants. Systemic chemotherapy is recommended for those tumors with a significant risk of distant metastases. Increasingly, neoadjuvant chemotherapy is being used to determine responsiveness to chemotherapy, which can help physicians select patients who may benefit from systemic postoperative therapy. Traditional predictors of treatment failure for soft tissue sarcomas include larger tumor size, high-grade histology, and positive surgical margins. The advent of more advanced reconstructive techniques, including free tissue transfer, has made more aggressive surgical resection of these tumors possible. Nevertheless, a considerable number of ancillary support staff are critical to the patient's postoperative rehabilitation and eventual return to a satisfactory level of function and quality of life. In the future, the discovery of the molecular pathogenesis of specific tumor types, such as the cytogenetic findings in synovial sarcoma, will improve physicians' prognostic abilities and selection of patients who are most likely to benefit from emerging adjuvant therapies.

Abstract
AIMS The aim of this study was to report prognostic factors, end-points of local recurrence, distant recurrence, post-metastasis survival, and overall survival in a cohort of patients with soft tissue sarcomas. METHODS We analysed a database of 395 patients affected by primary soft tissue sarcomas of various primary sites, treated and followed up at the Centro di Riferimento Oncologico, Aviano, Italy from January 1985 to January 1997. RESULTS Grade, size, stage, surgical margins, distant metastasis, age, sex, performance status, and haemoglobin value were significant for overall survival. Histology, grade, stage, and surgical margins were significant for local recurrence. Grade, size, and stage, were significant for distant recurrence; and surgical margin was significant variable for post-metastasis survival. CONCLUSIONS Grade, size, and TNM stage (UICC/AJCC) have stronger prognostic significance for overall survival and distant recurrence than for local relapse. Positive surgical margins are the main predictors for local relapse. Age was the most consistent adverse independent prognostic factor for survival.

Abstract
Radiotherapy and limb-preserving surgery has replaced amputation and compartmental resection for treatment of soft tissue sarcomas. However, the role of radiotherapy in low-grade tumors remains unclear. This study reviews the outcomes of 132 patients who received multimodality treatment for low-grade soft tissue sarcoma. Large primary tumors (> 5 cm) and the absence of radiotherapy correlated with local recurrence. Radiotherapy was most effective in patients operated on with marginal margins. Patients who were treated with wide surgical margins or had small tumors (< or =5 cm) showed no benefit with adjuvant radiotherapy. Size greater than 5 cm and local recurrence correlated with metastasis. Radiotherapy appears to be important in the management of low-grade soft tissue sarcoma. The principles of local treatment for low-grade soft tissue sarcoma should be the same as for high-grade tumors with a combination of surgery and adjuvant radiotherapy. In a subset of patients with small and widely excised tumors, consideration may be given to withholding radiotherapy. Local recurrence and metastasis from low-grade soft tissue sarcoma may occur as long as 1 decade after primary tumor resection. Long-term review of patients with low-grade tumors may be indicated.

Abstract
BACKGROUND The establishment of a universally acceptable staging system for soft tissue sarcomas has been hampered by the low incidence, various grading systems, and lack of consensus regarding the value of different prognostic factors. We aimed to evaluate prognostic factors in patients with extremity soft tissue sarcomas and to test the validity of the AJCC/UICC staging system. METHODS Prospectively collected data from 316 previously untreated patients with primary extremity soft tissue sarcomas treated at a single institution between 1989 and 1995 were studied. The influence of clinical and pathological factors on local recurrence, distant metastasis, and disease-specific survival was analyzed by univariate and multivariate techniques. RESULTS Large tumor size and high histological grade were independent adverse prognostic factors for distant metastasis. Large size, high grade, and positive microscopic surgical margins were independent adverse prognostic factors, and liposarcoma histology was an independent favorable prognostic factor for disease-specific survival. Within each histological grade, there was a progressive decline in survival with increasing tumor size, as reflected by an almost linear increase in hazard ratios. Similarly, there was a progressive fall in survival with increasing grade within each size group (<5 cm, 5 to 10 cm, 10 to 15 cm, and > 15 cm). AJCC staging did not correlate well with prognosis. Survival for intermediate-grade tumors smaller than 5 cm (stage IIA) was better than that for low-grade tumors larger than 5 cm (stage IB) (86% vs. 73%). Survival for high-grade tumors smaller than 5 cm (stage IIIA) was better than that for intermediate-grade tumors larger than 5 cm (stage IIB) (72% vs. 57%). A modified staging system was formulated based on the additive influence of size and grade on the estimated hazard ratios for disease-specific survival, as follows: stage IA, G1T1; stage IB, G1T2 or G2T1; stage IIA, G1T3 or G2T2 or G3T1; stage IIB, G1T4 or G2T3 or G3T2; stage IIIA, G2T4 or G3T3; stage IIIB, G3T4; and stage IV, M1 (G1, G2, G3 = low, intermediate, and high grade; T1, T2, T3, T4 = tumor size < 5 cm, 5-10 cm, 10-15 cm, and > 15 cm, respectively). The 5-year disease-specific survivals of stages IA, IB, IIA, IIB, IIIA, and IIIB were 100%, 83%, 74%, 61%, 39%, and 18%, respectively. The 5-year disease-specific survival for stages I, II, III, and IV were 90%, 67%, 31%, and 6% respectively. The survival difference between each stage was statistically significant (P < .001). CONCLUSION Histological grade and tumor size are equally important determinants of distant metastases and survival. The AJCC/UICC staging system is based primarily on the grade of the tumor, with size used to subgroup each stage. A staging system for extremity soft tissue sarcomas with equal emphasis on grade and size is proposed that correlates extremely well with prognosis.

Abstract
Soft tissue sarcomas (STS) are mesenchymal tumors arising from connective tissue elements and are grouped together based on a common biologic behavior. The most common histologic types include malignant peripheral nerve sheath tumors (schwannoma and neurofibrosarcoma) "hemangiopericytoma," fibrosarcoma, and malignant fibrous histiocytoma. These tumors are relatively slow growing yet locally invasive with a high rate of recurrence following conservative management. Appropriate preoperative planning and aggressive surgical resection often result in long-term remission or cure. Identification and evaluation of resection margins are paramount in appropriate case management. The addition of radiotherapy after surgical resection can aid in remission for incompletely resected masses. Systemic chemotherapy for STS should be considered for high-grade tumors with a moderate metastatic potential. Potential prognostic factors include grade, resection margins, size, location, histologic type, and previous treatment, with grade and margins being the most important. Tumor types classified as STS that differ slightly in their presentation or treatment, including synovial cell sarcoma, rhabdomyosarcoma, liposarcoma, and vaccine-associated STS in cats, are discussed. Soft tissue sarcomas can be a frustrating disease to treat, but adherence to solid surgical oncology principles can greatly increase the odds of good disease control.

Abstract
A case of a 44-year-old female who had an intrathoracic mass that was found to be a hemangiosarcoma of the anterior mediastinum is reported. Radical surgical incision through a right anterior thoracotomy was performed, followed by post-operative radiotherapy. Since this is a rare tumor at this location, the clinical and radiological findings, the histopathological appearances and its therapeutic management are discussed. Radiologists, surgeons and oncologists should in the differential diagnosis of a mediastinal mass include that of a tumor of vascular origin, even if it is rare. Radical excision followed by post-operative radiotherapy, especially in cases where the tumor has been partially excised, is the treatment of choice.
