Aim: To review treatment outcomes in patients with sacral chordoma treated at our centre over the past 20 years.

Methods: Retrospective review of prospectively kept data. Previously treated patients were excluded. The surgical objective was to obtain clear margins. If sacrifice of S2,3,4 was necessary, this was usually combined with colostomy.

Results: 30 patients were treated (20 males, 10 females), median age 63.5 (28 to 94). Median duration of symptoms before presentation was 79 weeks (3–260), mean tumour size 11 cm. Most had neurological symptoms. Eight tumours involved the S2 roots, 1 the entire sacrum. Treatment was palliative in 7 patients, resection in 23. Operation time averaged 4.5 hours (1.5 to 8). Margins were wide in 7, marginal in 12, and intralesional in 4 patients. There was a high rate of postoperative complications, mostly wound problems (61% of patients). In 1 case this resulted in septicaemia and post-operative death. Average operative blood loss was 1600ml (0–3500). 65% of patients were incontinent of urine and/or faeces. Local recurrence (LR) occurred in 52% of operated patients at a median of 32 months (4–134). Incidence of LR was 60% after intralesional, 57% after marginal and 25% after wide surgery (p=0.49). LR was treated with re-excision, radiofrequency ablation, radio- and occasionally chemotherapy. Overall survival (Kaplan-Meier) of all patients was 57% at 5, and 40% at 10 years. Of operated patients this was 67% and 47%. There was a trend for better survival after wide resection margin. Metastatic disease only occurred in 3 patients.

Conclusion: Chordoma of the sacrum is frequently diagnosed late. Resection is associated with a high complication rate. Local recurrence is the most common cause of death. Early referral to a specialist centre is recommended to optimize treatment. The role of adjuvant therapy remains unclear.

Aim: To identify tumour and treatment factors significant for both local control and survival for patients with chondrosarcoma of the pelvis.

Method: The features of all patients with non metastatic chondrosarcoma of the pelvis treated at a tertiary treatment centre between 1971 and 2001 with more than 2 years of follow-up were analyzed.

Results: There were 106 patients with a median age of 44. There were equal numbers of male and female patients in the group. The median size of the tumours was 12cm. 47 tumours were grade 1, 37 were grade 2 and 22 were grade 3. Treatment involved hindquarter amputation in 33 and excision with or without reconstruction in 73. Clear margins (wide or better) were achieved in 34 cases. The excision was marginal in 30 cases and intralesional or contaminated in 37. Local recurrence arose in 39 patients and was related to adequate margins of excision (p=0.03) and grade (p=0.01). Overall survival was 72% at 5 years, 56% at 10 years and 46% at 15 years. Survival was strongly related to grade (p=0.08) but survival beyond 5 years was most strongly related to the adequacy of the excision margins.

Conclusion: Tumour grade is the most important prognostic factor for chondrosarcoma of the pelvis but the ability to obtain clear margins of excision influences both local control and the prospects for long term survival.

Purpose of the study: To analyze survival and prognostic factors in a series of patients treated for chondrosarcoma of the pelvis.

Material and methods: The series included 106 patients (53 women and 53 men) treated for non-metastatic chondrosarcoma of the pelvis. Minimum follow-up was two years. Mean age at diagnosis was 44 years. Tumors were grade 1 (n=47), grade 2 (n=37), grade 3 (n=22). Conservative surgery was performed in 73 patients (resection with or without reconstruction) and interilio-abdominal disarticulation for 33.

Results: Resection margins were sufficient for 34 patients (wide or radical resection), marginal for 35, and intratumoral or malignant for 37. Local recurrence was noted in 39 patients (37%). Prognostic factors affecting local recurrence were: quality of resection (p=0.03), grade (p=0.01). Overall survival at 5, 10 and 15 years were 72, 56, and 46% respectively. Survival was strongly correlated with grade (p=0.08) and survival after five years was also correlated with resection margins.

Conclusions: In this series, tumor grade was the most important prognostic factor for patients with chondrosarcoma of the pelvis but achieving satisfactory resection with wide margins also has a significant effect on prognosis for local recurrence and long-term survival.

Pathological fracture occurs in 5–10% of all primary malignant bone tumours. It is thought that they unfavourably influence survival, because the fracture haema-toma may contaminate adjacent tissues. Management is often more aggressive and one is less inclined to consider limb saving surgery.

Aim of this study was to determine whether the presence of pathological fracture had an effect on rate of limb salvage surgery, role of adjuvant treatment and survival.

A retrospective study was done on all patients with a pathological fracture through localised Ewing’s sarcoma, treated between 1979 and 2001. Of 289 patients with localised Ewing’s sarcoma, 27 had a pathological fracture. Eighteen presented with fracture, in 9 fracture occurred after biopsy. All were treated with chemotherapy according to protocol. Two fractures were already treated by osteosynthesis elsewhere, the rest healed with conservative treatment. After chemotherapy, 20 patients were treated surgically: 19 with limb saving surgery, 1 with amputation. Apart from chemotherapy, treatment was surgery alone in 15, surgery and radiotherapy in 5, and radiotherapy alone in 7 patients. Indications for radiotherapy were close margins, poor chemotherapy response, or pelvic tumours. Surgical margins were wide in 16 patients, marginal in 2, and intralesional in 1 patient. Local recurrence occurred in 2 patients, primarily treated with chemotherapy and radiotherapy alone. Five year survival was 60%, metastasis free survival 59%, both comparable with rates reported in literature.

Conclusion: Chemotherapy allows fractures to consolidate with conservative treatment. Adequate surgical margins can be achieved in the majority of patients with limb saving surgery. Adjuvant radiotherapy does not seem necessary if margins are wide. Survival is not negatively influenced by pathological fracture. The survival rate following limb saving surgery in these patients is similar to that of patients in literature where amputation is done. Limb saving surgery seems a safe option.
