Objectives

As tumours of bone and soft tissue are rare, multicentre prospective collaboration is essential for meaningful research and evidence-based advances in patient care. The aim of this study was to identify barriers and facilitators encountered in large-scale collaborative research by orthopaedic oncological surgeons involved or interested in prospective multicentre collaboration.

Methods

All surgeons who were involved, or had expressed an interest, in the ongoing Prophylactic Antibiotic Regimens in Tumour Surgery (PARITY) trial were invited to participate in a focus group to discuss their experiences with collaborative research in this area. The discussion was digitally recorded, transcribed and anonymised. The transcript was analysed qualitatively, using an analytic approach which aims to organise the data in the language of the participants with little theoretical interpretation.

Objectives

The diagnosis of surgical site infection following endoprosthetic reconstruction for bone tumours is frequently a subjective diagnosis. Large clinical trials use blinded Central Adjudication Committees (CACs) to minimise the variability and bias associated with assessing a clinical outcome. The aim of this study was to determine the level of inter-rater and intra-rater agreement in the diagnosis of surgical site infection in the context of a clinical trial.

Materials and Methods

The Prophylactic Antibiotic Regimens in Tumour Surgery (PARITY) trial CAC adjudicated 29 non-PARITY cases of lower extremity endoprosthetic reconstruction. The CAC members classified each case according to the Centers for Disease Control (CDC) criteria for surgical site infection (superficial, deep, or organ space). Combinatorial analysis was used to calculate the smallest CAC panel size required to maximise agreement. A final meeting was held to establish a consensus.

We investigated the clinical outcome of internal fixation for pathological fracture of the femur after primary excision of a soft-tissue sarcoma that had been treated with adjuvant radiotherapy.

A review of our database identified 22 radiation-induced fractures of the femur in 22 patients (seven men, 15 women). We noted the mechanism of injury, fracture pattern and any complications after internal fixation, including nonunion, hardware failure, secondary fracture or deep infection.

The mean age of the patients at primary excision of the tumour was 58.3 years (39 to 86). The mean time from primary excision to fracture was 73.2 months (2 to 195). The mean follow-up after fracture fixation was 65.9 months (12 to 205). Complications occurred in 19 patients (86%). Nonunion developed in 18 patients (82%), of whom 11 had a radiological nonunion at 12 months, five a nonunion and hardware failure and two an infected nonunion. One patient developed a second radiation-associated fracture of the femur after internal fixation and union of the initial fracture. A total of 13 patients (59%) underwent 24 revision operations.

Internal fixation of a pathological fracture of the femur after radiotherapy for a soft-tissue sarcoma has an extremely high rate of complication and requires specialist attention.

Introduction

Fibromatosis is a disorder characterised by a spectrum of biological behaviour from relative indolence to aggressive local infiltration. With aimed to describe the pre and post-operative functional status of these patients managed with surgery and analyse the effect of radiotherapy on functional outcome.

Methods

43 patients were analysed in the upper and lower limb fibromatosis database in which functional data was available pre-op and at a minimum of two years post-op. Any plantar, palmer, chest or abdominal lesion was excluded as were hormonal or chemotherapy treated patients.

Fibromatosis represent a highly heterogeneous group of tumours in growth pattern, location and management. Our aim was to describe the demographics of the patient population who had undergone surgical resection and to identify predictors of local recurrence. Any lesion that was infiltrating the chest or abdominal cavity was excluded. Patients were also not included if they had a plantar or palmar lesions or had received hormonal or chemotherapy.

67 men and 88 women aged from 16 to 77 with a median age of 39 were analyzed. 121 patients had no prior resective operative intervention. 34 patients had undergone an attempted resection procedure at another unit of which 30 had locally recurred. 3 were located in the abdominal wall, 5 chest wall, 15 paraspinal, 56 lower and 76 upper limb. 40 patients did not receive XRT, 18 in the post-operative period and 97 in the pre-operative period. 67 operations produced margin negative resection, 85 were positive and 3 in which the margin status was unknown. Follow-up ranged from 1 day post op to 23.3 years. 23 patients had a local recurrence. Following subsequent re-resections, the total number of patients who were alive with evidence of disease was 16.

6 pts had deceased. 149 were alive with no evidence of disease. No factors were found to be statistically significant for predicting local recurrence, including the use of radiation (0.06) and margin status (0.81). Although radiation, given either pre or post-operatively did trend towards preventing local recurrence (HR 0.40; 95% CI 0.15 to 1.06; p = 0.06).

Conclusions

The retention of critical structures whilst resecting fibromatosis continues to be an appropriate management strategy, as local recurrence rates seem to be independent of margin status. Although not statistically significant, the use of XRT did tend towards reducing local recurrence.
