It is a well-accepted tenet that wide surgical margins are necessary for the treatment of soft-tissue sarcomas, and it is still true that the rate of recurrence depends on the adequacy of the surgical margins. Sarcomas that rest directly against bone pose a dilemma for the surgeon. A wide margin is not possible in the literal sense without excision of the bone. Whereas reconstruction of skeletal defects is possible, it adds to the complexity of the surgery and increases potential complications. We report the experience of treatment in a case of synovial sarcoma which located at popliteal fossa adjacent to proximal tibia.

Pulmonary artery sarcomas are rare, high-grade malignancies, primarily affecting the proximal elastic pulmonary artery and usually manifesting as tumoral impaction on imaging. Due to similar clinical and imaging findings, pulmonary artery sarcomas are frequently misdiagnosed as pulmonary thromboembolism or, occasionally, as vasculitis. Herein, we reported a case of pulmonary artery intimal sarcoma initially misdiagnosed as pulmonary thromboembolism and vasculitis due to its relatively atypical location and morphology, along with a literature review.

Background: Primary cardiac tumors are extremely rare. The most common type are benign myxomas, and these are almost completely curable with early surgery. Malignant tumors, however, such as sarcomas, are difficult to remove surgically, and their prognosis is known to be poor. In this study, data on patients who had undergone surgical treatment of cardiac tumor in the authors' hospital were collected and analyzed. Material and Method: The subjects included 28 patients who had undergone surgical treatment of cardiac tumor from August 1993 to December 2008. Their medical records were reviewed and retrospectively analyzed. Result: The patients were aged from 20 to 76 years (mean age: $54.2{\pm}15.6$), and 11 were male (39%) and 17 female (61%). Fifteen of them (54%) underwent emergency surgery to improve heart failure symptoms. The most common preoperative symptom was dyspnea (15 cases, 54%). Preoperative echocardiography was performed on all the patients. The average size of the tumor as measured during the operation was $7.0{\pm}6.9cm$ (the average length of the long axis was 2∼40 cm), and the sites of tumor attachment were the interatrial septum (18 cases, 64%), the left atrium (9 cases, 32%), the mitral valve annulus (2 cases, 7%), and the left ventricle (2 cases, 7%). The operation was performed with an incision through both atria in all the patients, and a complete excision was made in 25 cases (89%). According to the biopsy results, there were 4 cases of sarcoma (14%), 1 case of lipoma (4%), and 23 cases of myxoma (82%). The three cases in which the tumors were not completely excised were sarcomas. No operative deaths occurred after the operations. Outpatient follow-up was possible for 24 cases (86%), with a mean follow-up period of $46.8{\pm}42.7$ months. Late death occurred in 3 of the 24 patients; each of these patients had sarcomas. Of these patients, the first had undergone two repeat surgeries, the second had metastatic sites removed, and the last had only chemotherapy. The average recurrence time was $12.7{\pm}10.8$ months, and the average metastasis time was $20.5{\pm}16.8$ months. Conclusion: Most cardiac tumors are benign myxomas. In principle, they should be surgically treated because they can create risks such as embolism, and can be radically treated when surgically removed. In most cases, however, malignant sarcomas are already considerably advanced with severe infiltration into the neighboring tissues at the time of diagnosis. The surgical removal of malignant sarcomas is known to be difficult because of the advanced stage and degree of infiltration. We suggest that excision of the removable portion of the tumor sites to alleviate symptoms such as heart failure can improve quality of life.

Objective: To analyze clinicopathological characteristics, prognostic factors and survival rates of the patients with urological soft tissue sarcomas treated and followed up in Turkey. Materials and Methods: For overall survival analyses the Kaplan-Meier method was used. From medical records, nine prognostic factors on overall survival were analysed. Results: For the 53 patients (34 males, 19 females) whose charts were reviewed, the median age was 53 (range 22 to 83) years. Most frequently renal location (n=30; 56.6%) was evident and leiomyosarcoma (n=20, 37.7%) was the most frequently encountered histological type. Median survival time of all patients was 40.3 (95% CI, 14.2-66.3) months. In univariate analysis, male gender, advanced age (${\geq}50years$), metastatic stage, unresectability, grade 3, renal location were determined as worse prognostic factors. In multivariate analysis, metastatic stage, unresectability and grade 3 were determined as indicators of worse prognosis. Conclusions: Urological soft tissue sarcomas are rarely seen tumours in adults. The most important factors in survival are surgical resection, stage of the tumour at onset, grade and location of the tumour, gender and age of the patients.

Background: Soft tissue sarcomas (STS) must be managed with a team involving pathologists, radiologists, surgeons, radiation therapists and medical oncologists. Treatment modalities and demographic charasteristics of Turkish STS were analysed in the current study. Material-Methods: Primary adult STS followed between 1999-2010 in Cukurova University Medical Faculty Department of Medical Oncology were analzied retrospectively Results: Of the total of 498 patients, 238 were male and 260 female. The most seen adult sarcomas were leomyosarcoma (23%). Localization of disease was upper extremity (8.8%), lower extremity (24.7%), head-neck 8.2%, thoracic 8%, retroperitoneal 5.6%, uterine 12.4%, abdominal 10%, pelvic region 3.6 and other regions 10%. Some 13.1% were early stage, 10.2% locally advanced, 8.2% metastatic and 12.2% recurrent disease. Patients were treated with neoadjuvant/adjuvant (12%) or palliative chemotherapy (7.2%) and 11.4% patients did not receive chemotherapy. Surgery was performed as radical or conservative. The most preferred regimen was MAID combination chemotherapy in the rate of 17.6%. The most common metastatic site was lung (18.1%). The overall survival was 45 months (95%CI 30-59), 36 months in men and 55 months in women, with no statistically significant difference (p=0.5). The survival rates were not different between the group of adjuvant and palliative chemotherapy (respectively 28 versus 18 months) (p=0.06), but radical surgery at 37 months was better than 22 months for conservative surgery (p=0.0001). No differences were evident for localization (p=0.152). Locally advanced group had higher overall survival rates (72 months) than other stages (p=0.0001). Conclusion: STS can be treated successfully with surgery, chemotherapy and radiotherapy. The survival rates of Turkish people were higher in locally advanced group; these results show the importance of multimodality treatment approach and radical surgery.

Background: Soft tissue sarcomas (STS) are a heterogeneous group of tumors, and approximately 40-50% of patients with STS develop metastatic disease. The median overall survival of those patients was 12 months and their 5-year survival rate was 8%. Therefore, study on more effective treatment, especially the targeting therapies, is urgently needed. Objective: To evaluate the efficacy and safety of Endostar$^{(R)}$ combined with chemotherapy in patients with advanced STS. Methods: A retrospective case-series study was conducted in Cancer Institute of PLA, Xinqiao Hospital. A total of 71 patients suffering from advanced STS (IIB - IV) were included, of whom 49 cases treated with chemotherapy alone were defined as the control group and the rest 22 cases treated with the traditional chemotherapy combined with Endostar$^{(R)}$ were defined as the test group. The short-term therapeutic effects including objective response rate (ORR), disease control rate (DCR) and safety were evaluated in the two groups. In the follow-up, progression-free survival (PFS) and overall survival (OS) were also observed. Results: In the test and control groups, the ORR was 18.2% and 12.2%, respectively (P=0.767), and the DCR was 86.4% and 61.2%, respectively (P=0.034). The median time to progression in the test and control groups was 120 days and 70 days with significant difference (P = 0.017), while the median overall survival was 452 days and 286 days without significant difference (P=0.503). The one-year survival rate in the test group and control group was 56.2% and 35.4%, respectively, while the two-year survival rate was 30.2% and 26.5%, respectively. No significant difference in the side effects was found between the two groups. Conclusions: Endostar$^{(R)}$ combined with chemotherapy resulted in a higher DCR and longer PFS in the patients with advanced STS, and the toxicity was tolerable.

Primary sarcomas of the lung are rare malignant neoplasms which have usually been classified as fibrosarcomas or leiomyosarcomas. Only 10 cases of primary malignant fibrous histiocytoma [MFH] of the lung have previously been reported in the literatures. The histomorphology of the MFH is marked by their extensive cellular variability, nuclear atypia, abnormal mitotic figures and storiform arrangement of the cells. Recently, we experienced a case of MFH, arising in the parenchyme of lung in 66-year-old male patient, and treated with surgical intervention. So we firstly reported it with review of literatures.

Ewing`s sarcoma is a highly malignant tumor which occurs most frequently in the diaphysis of the long bones, although any bone may be involved. Ewing`s sarcomas occurring in the rib are rare. Recently, we experienced one case of Ewing`s sarcoma which arose in the right second rib in a young female patient. She was treated with three principal treatment modalities-en bloc excision of chest wall followed by radiation therapy and chemotherapy. Clinical course is described with review of related literatures.

Primary sarcomas of the pulmonary arteries are and the clinical presentation closely resembles several more common conditions, Therefore they are seldomly diagnosed preoperatively without a pathologic esxamination of sufficient surgical specimen. Treatment of these tumors remains primarily surgical as possible and the role of the adjuvant chemotherapy and radiotherapy is not yet evident We report a case of primary sarcoma of pulmonary artery clinically suspected of carcinoid partially involving the pulmonary parechyme and the bronchus mainly in the left main pulmonary artery and the vein with left intrapericardial pneumonectomy.
