Purpose: We analyzed the nature of primary chondrosarcoma of the pelvis, along with long-term survival, complications, and functional outcomes.
Materials and Methods: Twenty-five cases of pelvic chondrosarcoma were enrolled. The average age was 40 (range: 17-69) years. The stage was IB in 5, IIB in 20. All of the 25 cases had underwent internal pelvectomy. Twelve cases had resections involving the acetabulum, while 7 involved the iliac wing and 6 involved the pubic bone. Study points were the reconstructive methods according to the extent of resection and the functional results, complications, local recurrence and the metastasis pattern following the clinical factors affecting long-term survival.
Results: The 16-year CDF survival of 25 cases following operation was 78.7%. Three (12%) local recurrences and 3 metastases occurred. The MSTS score of the iliac and pubic resection group was 25.3. Of 12 cases with acetabular resection, 6 had prosthetic arthroplasty, 4 had psuedoarthrosis, 1 had arthrodesis, and 1 had excision. Their overall MSTS score was 19.4. There were 2 infections, 1 flap necrosis, 1 screw failure and 2 hip dislocations. Of 11 cases of a high grade (G3), there were 3 metastases and 1 local recurrence.
Conclusion: The long-term survival rate was good and the pathologic grade had some correlation with prognosis. Because acetabular reconstructions of any kind may involve serious complications, primary pseudoarthrosis can be regarded as an alternative option
