Abstract
Purpose- To review the operative treatment of patients with chondrosarcoma of the pelvis and to study the long-term survival analysis of this cohort group.
Methods- A retrospective case study analysis was performed of patients with a diagnosis of chondrosarcoma of the pelvis treated in our hospital between 1990 and 2003. The operative notes and histopathological records were used along with the latest follow up letters.
Results- 54 cases (32 males and 22 females) with a mean age of 48.4 years ( 18–77) were identified. The aetiology was primary ( 38), recurrences ( 9) and secondaries ( 7).The sites in the pelvis were in the anatomical epicentre I(24), II(20) and III(10).The surgical procedures performed were local resection (28) , local resection and hip arthoplasty (6), hemipelvectomy (+ endoprosthesis) (16), hemipelvectomy (+ fibular strut graft) (2) and hindquater amputation (2).The histological grade was grade 1 (27), grade 2 (20) and grade 3(7). The complications rate was 24% – Wound revision (9%), dislocation (8%) and infection (7%). There was a 14-year cumulative survival rate of 46 % and 24 patients are surviving to date. The median follow up was 52 months.
The cumulative 14-year recurrence rate was 40% and the mean time to recurrence was 20.2 months.
Conclusion- There is an increased recurrence rate with epicentre I and III tumours and with those treated by local excision.
