[Midterm results after treatment of liposarcoma in the extremities].
Zeitschrift Für Orthopädie und Ihre Grenzgebiete 2003 November
PURPOSE: In this retrospective analysis, survival time, local recurrence and rate of metastasis were appraised in patients with primary liposarcoma of the extremities 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 tumour.
MATERIAL AND METHOD: Between 1990 and 1998, 27 patients were surgically treated who suffered from a primary liposarcoma of the extremities. At the mean follow-up time of 62.4 months (39-141 months) postoperative survival rate, rate of metastasis and local recurrence were determined. The results were analysed with regard to intraoperative resection distance, tumour size and localisation as well as histological classification of previous biopsy and finally resected tumour. The influence of radiotherapy on the results was also determined.
RESULTS: In 5 patients (18.5%) the amputation and in 22 cases (81.5%) the limb sparing resection of the liposarcoma was performed. 6 patients underwent a marginal resection and one patient 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 patients had metastases. After adjuvant radiotherapy three patients (50%) showed local recurrence after marginal resection. In only 8 cases (29.6%) the results of primary biopsy and final tumour classification (entity, subtype and grading) were identical.
CONCLUSION: The development of metastases (often pulmonary) and local recurrences even after long tumour-free interval makes adequate follow-up investigations mandatory in liposarcoma patients. With regard to the problems in assessing liposarcoma biopsies, MRI-orientated biopsies from several tumour areas via one biopsy approach are recommended.
