Background

Recent meta-analyses have shown reduced re-rupture rates for the surgical management of Achilles ruptures. However percutaneous repair has been demonstrated to lead to improved function, patient satisfaction but greater complications than open repair. In the current economic climate, we believe it is reasonable to consider the financial cost of rupture management for both the patient and the provider. We aimed to determine the cost effectiveness of operative treatment of ruptures of the Achilles tendon based upon theatre occupancy, clinic attendance and cast changes, operative complications and functional assessment score.

Soft tissue sarcomas (STS) arising in the adductor compartment of the thigh are frequently large before clinical detection, posing particular challenges with surgical resection and associated with a high risk of wound complications. This study compares oncological and functional outcomes and complications following treatment of adductor compartment soft tissue sarcomas from three international centres with different treatment philosophies.

184 patients with new primary, non-metastatic, deep STS in the adductor compartment diagnosed between 1990 and 2001 were identified from the centres' local databases. The Toronto Extremity Salvage Score (TESS) was used to assess function in patients.

There were 94 male and 90 female patients, with ages ranging from 13 to 88 years (median age 57 years). The period of follow-up ranged from 1 to 162 months. The overall survival was 65% at 5 years and related to grade and size of the tumour. There was no difference in overall survival or systemic relapse between the three centres. There was however a significant difference in local control (28% LR in centre 1 compared to 10% in centre 2 and 5% in centre 3, which appeared to be principally related to the use of radiotherapy and surgical margins.)

66 patients (36%) from the three centres developed wound complications post-operatively and it was shown to be associated with high grade and large tumours (>10cm).

Functional scores averaged 78% but were significantly worse for patients with wound complications or high-grade tumours; however, they were not affected by timing of radiotherapy or use of prophylactic free muscle flaps.

Ewing’s sarcoma principally arises in bone but can also present as a soft tissue tumour. Very few studies have assessed the outcomes of extra-skeletal Ewing’s sarcomas. This study compares the oncological outcomes of the two forms of Ewing’s sarcomas to see if there is any difference in prognostic factors.

198 patients with primary, non metastatic Ewing’s sarcoma diagnosed between 1980 and 2005 were identified from our database. There were 118 males and 80 females with a median age of 15 years. The three most common sites of diagnosis were the femur (24%), pelvis (15%) and tibia (13%). There were 169(85%) bony Ewing’s and 29 (15%) extra-skeletal Ewing’s sarcomas. All patients received chemotherapy. 86% of the patients had surgery for local control but 28(14%) patients had radiotherapy.

The overall survival at five years was 89% and was related to the age of patient (92% < 16years p=0.005), size (p=0.03) and site of tumour (p=0.004) as well as the response to chemotherapy. There was no difference in the overall survival of patients with bony Ewing’s (90%) and extra-skeletal Ewing’s (85%) (p=0.85). There was a 10% risk of local recurrence at 5 years with site of tumour (p=0.01) and surgical excision (p=0.05) being significant prognostic factors. The risk of local recurrence was also not related to the type of Ewing’s sarcoma.

This large series has shown that the oncological outcomes of Ewing’s sarcoma is related to tumour characteristics, patient age and treatment factors and not determined by the tissue component.
