BACKGROUND: @entity1821 is the single most common soft tissue @entity242 in the retroperitoneum. MATERIALS AND METHODS: A retrospective review of @entity1 with primary @entity27418 treated between June 1990 and June 2005 were conducted to evaluate the clinical results of resection for @entity27418 ( @entity27418 ) and the prognostic factors for disease recurrence and @entity1 survival in an Asian population. RESULTS: Twenty-one @entity1 operated on for curative intent (12 Males, 9 Females; mean age: 52.4 years) were evaluated. Of these, 13 presented with @entity5 that were well differentiated (61.9%), 4 (19.0%) with myxoid/round cell, 3 (14.3%) with dedifferentiated and 1(4.8%) with pleomorphic morphology. The median @entity5 burden was 36 cm (9-83). Median follow-up time was 62 months. There was no peri-operative mortality and morbidity occurred in 6(28.6%) @entity1 . Surgical margins were involved in 10(47.6%) @entity1 . Resection of contiguous organs was required in 15(71.4%) to achieve gross surgical margins. Eleven out of the 21(52%) of the @entity1 had recurrence of the @entity5 . Median disease-free survival was 19 months and the overall 3- and 5-year survival rate was 87% and 49% respectively. CONCLUSION: An aggressive surgical approach in both primary and recurrent @entity27418 in our institution is associated with 3- and 5-year survival rate of 87% and 49% respectively. Contiguous organ resection is often required to achieve local control.
