[Midterm results after treatment of XXXX in the extremities].

@entity1 @entity1821 @entity5 @entity3
PURPOSE: In this retrospective analysis, survival time, local recurrence and rate of @entity3 were appraised in @entity1 with primary @entity1821 depending upon the applied primary and adjuvant therapy procedures. Furthermore, we compared the representativity of histological results of the biopsy with the final histology of the resected @entity5 . MATERIAL AND METHOD: Between 1990 and 1998, 27 @entity1 were surgically treated who suffered from a primary @entity1821 . At the mean follow-up time of 62.4 months (39-141 months) postoperative survival rate, rate of @entity3 and local recurrence were determined. The results were analysed with regard to intraoperative resection distance, @entity5 size and localisation as well as histological classification of previous biopsy and finally resected @entity5 . The influence of radiotherapy on the results was also determined. RESULTS: In 5 @entity1 (18.5%) the amputation and in 22 cases (81.5%) the limb sparing resection of the @entity1821 was performed. 6 @entity1 underwent a marginal resection and one @entity1 an intralesional resection. At follow-up we observed a local recurrence rate of 22.2% (n = 6) and a survival rate of 74.1%. 18.5% of the @entity1 had @entity3 . After adjuvant radiotherapy three @entity1 (50%) showed local recurrence after marginal resection. In only 8 cases (29.6%) the results of primary biopsy and final @entity5 classification (entity, subtype and grading) were identical. CONCLUSION: The development of @entity3 (often pulmonary) and local recurrences even after long @entity5 -free interval makes adequate follow-up investigations mandatory in @entity1821 @entity1 . With regard to the problems in assessing @entity1821 biopsies, MRI-orientated biopsies from several @entity5 areas via one biopsy approach are recommended.
