ABSTRACT
BACKGROUND: The Korean Bone and Soft Tissue Pathology Study Group of the Korean Society of Pathologists conducted a nationwide retrospective analysis of soft tissue sarcoma (STS) to provide the clinicopathologic characteristics of STS within the population of the Republic of Korea. METHODS: The cases of STS were collected during a 7-year period (2001-2007) from 19 institutes in Korea. All cases were classified according to the histologic criteria proposed by the World Health Organization. Clinicopathologic data were reviewed. RESULTS: Data from 722 patients (median age, 50 years) were collected. Data showed a slight male predominance. The most frequent types of STS in decreasing order were liposarcoma, malignant fibrous histiocytoma, leiomyosarcoma, and synovial sarcoma. STS occurred throughout the body, although approximately half (47.8%) were located in the extremities. The majority of STS was histologically classified as high grade with a large tumor size (>5 cm). The overall survival rate for the patients was 76.3% (median follow-up time, 26 months; range, 1 to 89 months). Histologic grade, tumor size, American Joint Committee on Cancer stage, tumor site, and resection status were prognostic. Significant independent adverse prognostic factors were large tumor size (>5 cm) and tumor site other than extremities. CONCLUSIONS: We reported the distribution and characteristics of STS in the Republic of Korea.
