  • Purpose: Evaluation of results of free flap as a method of reconstruction in soft tissue defect after wide excision of soft tissue tumor of extremity. Materials and Methods: From 2000 through 2007, 11 patients received free flap surgery for soft tissue defect after wide excision operation for soft tissue tumor of limbs. Four cases were upper extremities and seven were lower extremities. Four subjects were diagnosed as squamous cell carcinoma, three as malignant melanoma, two as synovial sarcoma and one as malignant fibrous histiocytoma and alveolar soft part sarcoma. Donor sites of free flap varied with anterolateral thigh flaps in six cases, latissimus dorsi flaps in four, reverse forearm flap in one. By the method of doppler ultrasound, venous circulation was evaluated for the survival of each flap on the third, fifth and seventh day respectively after the operation. Results: 10 of 11 free flaps were successfully survived. Necrosis of free flaps in 1 cases occurred in case of anterolateral thigh flap. Conclusion: Free flap can be a useful method for reconstruction of soft tissue defect after wide excision of soft tissue sarcoma of extremity.

  • There were many difficulties in the treatment of extensive, massive, and composite defect in the lower extremity until early 1980's. Recently, microscopic reconstruction of wide soft tissue defect is popularized. But, the combined flap, which requires wide coverage of lower extremity after soft tissue sarcoma excision or traffic accident, is still challenging to the orthopaedic surgeons. We experienced 12 cases of combined scapular and latissimus dorsi flap from 1983 to 1997 in the lower extremity reconstruction of soft tissue defect with satisfactory result. There were no serious donor site complications such as functional disturbance of shoulder joint.

  • Purpose: Soft tissue sarcoma (STS) is a rare and heterogeneous cancer with over 50 known subtypes. It is difficult to understand the role of adjuvant treatment in STS. We aimed to determine the benefits of adjuvant treatment for a rare STS subset: non-extremity STS with moderate chemosensitivity. Materials and Methods: We reviewed medical records from Pusan National University Hospital and Kosin University Gospel Hospital, which had detailed pathological reports on patients diagnosed between 2006 and 2016. The most important inclusion criterion was resection with curative intent. We grouped STS by chemosensitivity based on reported data and analyzed non-extremity STS with moderate chemosensitivity. Results: We investigated 142 patients with 20 pathological subtypes of STS. Eighty-six patients had extremity STS and 56 had non-extremity STS. Thirty-eight of 56 patients were categorized as having moderate chemosensitivity. Seventeen of 38 patients (44.7%) received adjuvant radiotherapy and 14 (36.8%) received adjuvant chemotherapy. A log-rank test showed longer disease-free survival (DFS) in the adjuvant radiotherapy group than in the group treated without adjuvant radiotherapy (not reached vs. 1.468 years, p = 0.037). Multivariate Cox proportional hazard analysis, with covariates including age, stage, resection margin, adjuvant chemotherapy, and adjuvant radiotherapy, revealed that adjuvant radiotherapy was associated with longer DFS (odds ratio = 0.369, p = 0.045). Overall survival was not correlated with adjuvant radiotherapy. Conclusion: Adjuvant radiotherapy may be associated with longer DFS in patients with non-extremity STS with moderate chemosensitivity.

  • Purpose: Compared to soft tissue sarcoma, the relative risk of extraskeletal osteosarcoma is still not clear. The purpose of this study is to identify the difference in survival and local recurrence rate between two soft tissue sarcomas. Materials and Methods: Twelve patients with pathologically confirmed extraskeletal osteosarcoma were analysed. For retrospective matched case-control study, we selected 72 patients who were confirmed as high grade soft tissue sarcoma and had similar tumor location, tumor size and age to extraskeletal osteosarcoma. Results: Median age was 50 years old. Five cases were located in upper extremity, four in the buttocks, three in the lower extremity. Overall survival rate of extraskeletal osteosarcoma group and high grade soft tissue sarcoma group at 5 years were 52% and 55%. There is no significant difference (p=0.8). Local recurrence rate and metastasis rate were 58%, 67% in extraskeletal osteosarcoma group and 36%, 51% in soft tissue sarcoma group, which were not stastistically significant(p=0.2, p=0.4). Conclusion: Extraskeletal osteosarcoma have similar local recurrence, metastasis and survival rate compare to high grade soft tissue sarcoma. The number of patients of this study were too small to identify outcome of extraskeletal osteosarcoma. Further multi-institutional study should be attempted.

  • A dosimetric evaluation of volumetric modulated arc therapy, intensity modulated radiation therapy, and three-dimensional conformal radiation therapy for the lower extremity soft tissue sarcoma For the lower extremity soft tissue sarcoma, volumetric modulated arc therapy, intensity modulated radiation therapy, and three-dimensional conformal radiation therapy were evaluated to compare these three treatment planning technique. The mean doses to the planning target volume and the femur were calculated to evaluate target coverage and the risk of bone fracture during radiation therapy. Volumetric modulated arc therapy can reduce the dose to the femur without compromising target coverage and reduce the treatment time compared with intensity modulated radiation therapy.

  • Synovial sarcoma is a rare soft tissue tumor accounting for 5-10% of soft tissue sarcomas. Most arise in the extremities and trunk, and a small proportion occur in the abdominal wall, head and neck legion, and mediastinum. It manifests different phenotypic subtypes that render their cytologic evaluation challenging. Moreover, cytomorphologic description of the epithelial component of synovial sarcoma is rare in Korea. We report a case of biphasic synovial sarcoma on the right lower extremity in a 49-year-old woman diagnosed by fine needle aspiration cytology. The aspirate was moderately cellular and composed of a mixture of tissue fragments and dissociated cells with bland chromatin, inconspicuous nucleoli, and oval to spindle-shaped cytoplasm. Mitosis was rare. A monolayer sheet of epithelial component was seen. The cells in this monolayer sheet had more abundant distinct cytoplasm, round nuclei, and prominent micronucleoli. Histologic examination showed a biphasic pattern consisting of mostly sarcomatous stroma and a few small glandular areas at the periphery of the tumor.

  • Purpose: To evaluate the treatment outcome and prognostic factor of postoperative radiotherapy for extremity soft tissue sarcoma (STS). Materials and Methods: Forty three patients with extremity STS were treated with conservative surgery and postoperative radiotherapy from January 1981 to December 2010 at Korea University Medical Center. Median total 60 Gy (range, 50 to 74.4 Gy) of radiation was delivered and 7 patients were treated with chemotherapy. Results: The median follow-up period was 70 months (range, 5 to 302 months). Twelve patients (27.9%) sustained relapse of their disease. Local recurrence occurred in 3 patients (7.0%) and distant metastases developed in 10 patients (23.3%). The 5-year overall survival (OS) was 69.2% and disease free survival was 67.9%. The 5-year local relapse-free survival was 90.7% and distant relapse-free survival was 73.3%. On univariate analysis, no significant prognostic factors were associated with development of local recurrence. Histologic grade (p = 0.005) and stage (p = 0.02) influenced the development of distant metastases. Histologic grade was unique significant prognostic factor for the OS on univariate and multivariate analysis. Severe acute treatment-related complications, Common Terminology Criteria for Adverse Events (CTCAE) grade 3 or 4, developed in 6 patients (14.0%) and severe late complications in 2 patients (4.7%). Conclusion: Conservative surgery with postoperative radiotherapy achieved a satisfactory rate of local control with acceptable complication rate in extremity STS. Most failures were distant metastases that correlate with tumor grade and stage. The majority of local recurrences developed within the field. Selective dose escalation of radiotherapy or development of effective systemic treatment might be considered.

  • Synovial sarcoma is rare soft tissue tumor mesenchymal origin. Osseous involvement of synovial sarcoma is rare. A 24-year-old man presented with pain and swelling of the lower extremity. MRI of the lower extremity demonstrated a large mass encircling tibia with osseous involvement. Surgical excision of the mass was done and the mass was diagnosed as biphasic synovial sarcoma with bone marrow involvement. We also discuss the other imaging findings of synovial sarcoma on MRI.

  • A total of 44 patients with extremity soft tissue sarcomas had received conservative surgery and radiation therapy in the Department of Radiation Oncology, Yonsei Cancer Center, Yonsei University College of Medicine between Jan. 1980 and Dec. 1990. Initial surgical treatment consisted of intracapsular excision in 33 patients $(75\%),$ marginal excision in 9 patients, and wide excision in two patients. Total radiation doses were between 40Gy and 65Gy (median 60 Gy). Median follow-up period was 47 months. Overall actuarial 5-year survival rate was $76.9\%$ and 5-year recurrence free survival rate was $39.3\%.$ There was no statistically significant prognostic factors but the 5-year survival rates tended to be decreased in the patients with high grade tumors and treated with narrow surgical extent. Sixteen patients recurred during fellow-up (16/31, $51.6\%).$ The incidence of initial local recurrence was $22.6\%$ (7/31) and distant metastasis was $29\%(9/31).$ Of the 7 who did not have metastasis at diagnosis of local recurrence, 5 were submitted to a salvage treatment. All of them achieved local control and distant metastasis appeared in three of them. In conclusion, conservative surgery and radiation therapy in the patients with extremity soft tissue sarcomas was the effective treatment modality.
