Neoadjuvant chemotherapy for osteosarcoma improves outcomes for the majority, but if the chemotherapy does not work then the dilemma often arises as to whether to do limb salvage with a marginal (or worse) margin of excision or to do an amputation. If limb salvage is carried out with a close margin, does post operative radiotherapy make any difference? This study aims to address these questions.

Method

All patients with limb osteosarcoma, no metastases, a poor response to chemotherapy and either a marginal excision or primary amputation were identified from a prospective database. This group were investigated in terms of overall survival and local control.

Results

There were 182 patients in this category of whom 60 had an amputation, 105 limb salvage with marginal margins and 17 with an intralesional margin. Local recurrence (LR) arose in 41% of those with an intralesional margin, 22% of those with a marginal margin and 13% of those with an amputation. Radiotherapy was used in 21 of the 122 patients and the risk of LR was the same as in those who did not have radiotherapy. Neither age nor sex of the patient, size or site of the tumour affected the risk of LR. The overall survival for this group was 42% at 10 years. The survival was best in those with marginal margins (38%) than those with an amputation (28%) and worst for those with an intralesional margin (20%). Survival was worst in those who did develop LR, but no worse than in those having amputation

The outcome for patients with Ewing's sarcoma recurrence is poor. Local recurrences occur in 8%-25%of these patients. The aim of the study was to analyze the patients who had a local recurrence to identify factors predicting the local recurrence and if it could be prevented

Methods

A retrospective analysis of 650 patients who had a diagnosis of Ewing's sarcoma treated between 1975 and 2009 at a single institution was performed and 64 patients (10%) who had a local recurrence were identified and analysed.

Results

Fifteen patients had metastases at diagnosis.20 patients had chemotherapy and radiotherapy only while 44 had chemotherapy and surgery +/− post op radiotherapy. Thirteen patients who were suitable for post –operative radiotherapy could not receive the treatment due to various reasons like biological reconstruction. The estimated 5 years survival for the patients was 15%. The risk of local recurrence is higher if the tumour is located in the axial skeleton, treatment with chemotherapy and radiotherapy alone [location and size of the tumour precluding surgery]. The risk of local recurrence is higher if the tumour was in the fibula or radius. One out of three patients who have good response to chemotherapy still went on to develop a LR. The use of biological reconstruction and younger age group often resulted in deferral of post-operative radiotherapy. Location and type of treatment can predict LR. Surgery with clear margins and post-operative radiotherapy given when indicated may reduce the incidence of LR.

Introduction

Recently a great deal of interest has emerged in new techniques for resection of bone tumours, such as the use of computer guided surgery, joint sparing prostheses and epiphysiolysis. However, all the techniques may require narrower margins at resection than the traditional Enneking wide margins. The aim of the study was to look at the effect of width and tissue at surgical margins, together with the use of adjuvant therapy on locally recurrent disease and disease free survival.

Methods

The quality in terms of precise distance (mm) and tissue has been regularly reported by our pathologists for 5 years, prior to this it was reported as wide, marginal or intralesional. It is known from previous studies that 90% of locally recurrent disease for osteosarcoma and Ewings occurs within 2 years from surgery. Therefore all primary bone sarcomas of the pelvis and appendicular skeleton that underwent surgery between 1/1/2005 and 1/1/2008 were entered into the study group, giving at least 2 years follow up. The pathology records were reviewed and the quality of the margins and percentage tumour necrosis were recorded. Those patients who had suffered local or distal disease relapse or died were highlighted. Analysis was undertaken by Kaplan Meier survival curves with univariate and multivariate analysis.

Introduction

The pelvis has always been a difficult area for surgeons, with high complication rates from surgery and the perception of poor oncological outcomes. The aim of the study was to look at the surgical and oncological outcomes of pelvic tumours treated at our centre.

Methods

From the 3100 primary bone tumours seen at the ROH. Information was retrieved on 539 patients seen with a primary bone tumour of the pelvis. The demographic details, oncological and surgical outcomes were reviewed.

Introduction

Bone tumours rarely involve the joint surface as cartilage is thought to be a good barrier to tumour spread. When the tumour does cross the surface the surgeon is faced with the dilemma of whether to amputate the limb, resect it without reconstruction or reconstruct with an implant. This paper aims to investigate the oncological and functional outcomes of patients undergoing an extra-articular resection and reconstruction with an endoprosthesis.

Method

3100 patients have been seen in ROH with primary bone tumours. Patients were identified who had an extra-articular resection considered pre-operatively and the notes and imaging was reviewed. This group was subdivided into a group who did have an extra-articular resection (EAR) and those who either had an amputation or traditional through joint resection. The outcomes of the three groups (group 1 = no joint involvement, group 2 = EAR considered but not done and group 3 = EAR) were then compared in terms of oncological outcome, surgical margins and complications.

Between 1966 and 2001, 1254 patients underwent excision of a bone tumour with endoprosthetic replacement. All patients who had radiotherapy were identified. Their clinical details were retrieved from their records.

A total of 63 patients (5%) had received adjunctive radiotherapy, 29 pre-operatively and 34 post-operatively. The mean post-operative Musculoskeletal Tumor Society scores of irradiated patients were significantly lower (log-rank test, p = 0.009). The infection rate in the group who had not been irradiated was 9.8% (117 of 1191), compared with 20.7% (6 of 29) in those who had pre-operative radiotherapy and 35.3% (12 of 34) in those who radiotherapy post-operatively. The infection-free survival rate at ten years was 85.5% for patients without radiotherapy, 74.1% for those who had pre-operative radiotherapy and 44.8% for those who had post-operative radiotherapy (log-rank test, p < 0.001). The ten-year limb salvage rate was 89% for those who did not have radiotherapy and 76% for those who did (log-rank test, p = 0.02).

Radiotherapy increased the risk of revision (log-rank test, p = 0.015). A total of ten amputations were necessary to control infection, of which nine were successful. Radiotherapy may be necessary for the treatment of a bone sarcoma but increases the risk of deep infection for which amputation may be the only solution.

We prospectively reviewed 2440 Cemented Anantomical (side specific) AGC total knee replacements performed on 2074 patients between 2002 and 2008 in our unit. The surgery was performed by a number of surgeons, both Consultant and Trainee grades. 1357 underwent PCL sacrificing surgery with implantation of Posterior Stabilised Femoral Implant (Cam and Grove) and 1083 underwent PCL retaining surgery with implantation of a Non-Stabilised Femoral Implant. The mean age at date of surgery for Posterior Stabilised prosthesis was 69 years (range 23-94) and Non-Posterior Stabilised prosthesis was 70 (range 33-97) with no significant difference p< 0.05 (C.I 95%). Follow up at present mean 4 years (range 1-6 years).

11 patients underwent secondary patella resurfaced for anterior knee pain at a mean of 1.5 years following the index procedure (range 0.5-4.1 years) with 6 patients reporting a marked improvement in anterior knee pain post operatively. 3 patients underwent removal of patella buttons for symptomatic loosening at a mean of 2.7 years follow index procedure.

A total of 17 patients underwent a revision of either tibial or femoral components (0.7%). Indications for revision were infection in 11 patients, gross instability in 1 patient, periprosthetic fracture in 1 patient, persistent stiffness in 1 patient. 3 patients underwent revision for symptomatic loosening of the tibial component at a mean of 2.9 years (range 1.1-4.0).

These short to medium term results for the Anatomic AGC total knee replacement agree with published results from other centres.

Introduction

The aim of the study was to whether the bone grafting techniques used affected the long term stability of the acetabular implant.

Methods

41 patients treated with a cemented total hip replacement with pre-operative protrusio or central acetabular defects at surgery were identified. The severity of initial protrusio was determined on plain AP pelvis radiographs by measuring the distance of the medial acetabular wall from the ilio-ischial line. The post-operative and last follow-up x-rays were reviewed, the thickness of the medial wall and the centre-edge angle of the cup was measured.

EPRs are the treatment of choice following resection of tumours. These have been used for 39 years in our institution. There has been concern regarding the long term survival of endoprosthesis; this study investigates the fate of the reconstruction.

Methods

Between 1966 and 1995, 3716 patients were seen with a suspected neoplasm and 776 patients underwent EPRs. Patients receiving growing endoprostheses were excluded from the study as they invariably require revision, leaving 667 replacements. Insufficient data was available in 6 cases, leaving 661 patients in the study group. Information was reviewed concerning the diagnosis, survival of implant and patient, subsequent surgery, complications and functional outcome. Kaplan-Meier survival analysis was used for implant survival with end points defined as revision for mechanical failure (aseptic loosening, implant fracture, instability, avascular necrosis, periprosthetic fracture, pain and stiffness) and revision for any cause (infection, local recurrence and mechanical failure).

Results

Mean age at diagnosis was 34 years. Overall patient survival was 52.7% at 10 years and 45.7% at 20 years. The mean follow-up for all patients was 9 years, and for those patients who survived their original disease, the mean follow-up was 15 years. 227 (34%) patients underwent revision surgery, 75 patients for infection (33%), 36 patients for locally recurrent disease (16%) and mechanical failure in 116 patients (51%). With revision for mechanical failure as the end-point, implant survival was 75% at 10 years and 52% at 20 years. With revision any cause as an end-point implant survival was 58% at 10 years and 38% at 20 years. Overall limb salvage was maintained in 91% of patients at 10 years from reconstruction and 79% at 20 years. There was a significant difference between survival of implant between implantation sites, with the proximal humeral implant survival being the best and tibial reconstructions being the worst. The MTSS functional score was available on 151 patients, with a mean score of 25/30 (83%) at last follow-up visit.

Introduction

Despite the advances in adjuvant chemotherapy and surgical techniques, the diagnosis of a bone tumour still carries with it a significant risk of mortality. This study investigates factors affecting survival, in patients treated for malignant tumours of bone using Endoprosthetic replacement (EPR).

Methods

Our tertiary referral musculoskeletal tumour unit has taken referrals over 40 years. Electronic patient records have been prospectively kept on all patients seen since 1986 and data has been entered retrospectively for patients seen between 1966 and 1986. A consecutive series of 1264 patients underwent endoprosthetic reconstruction; after 158 patients were excluded, 1106 patients were left in the study group. Factors including diagnosis, size of tumour, surgical margins, percentage tumour necrosis following chemotherapy, tumour site, local recurrence, decade of reconstruction, fracture and post-operative deep infection were analysed.

Background: Malignant tumours of the radius compose only 3% of all upper limb tumours. Owing to their rarity they are often difficult to manage satisfactorily. Of the options for fixation available, endo-prosthetic replacements have been scarcely utilized despite their success in limb preservation with malignant tumours in other parts of the body. At our centre we have used these when biological solutions (eg fibula graft) were not indicated due to extensive disease or the need for radiotherapy.

Patients: We performed four endoprosthetic replacements of the distal radius in three males and one female with ages ranging from 19–66 years (average= 42.25 years of age). Two were performed for varieties of osteosarcoma (parosteal and osteoblastic osteosarcomas), one for a large destructive giant cell tumour (GCT) and one for destructive renal metastases. Three were right sided (75%) and one left sided (25%).

Methods: Medical records were evaluated for information on local recurrence, metastases, complications and functional outcome using the Toronto Extremity Salvage Score (TESS).

Results: Follow up ranged from 22 to 205 months (average= 116.5 months). The average TESS score was 58.1% (range= 44.6–74.5%). Neither case of osteosarcoma recurred. The GCT recurred twice and the patient with renal metastases had nodules removed from his affected wrist on two further occasions. There were no cases of infection, but one of the earlier cases had problems with metacarpal stems cutting out and joint subluxation. The two earlier cases have since died at 205 (parosteal osteosarcoma) and 189 months (GCT) respectively of other disease.

Conclusions: We conclude that although this is a very small series of endoprosthetic replacement of the distal radius, the technique is a useful addition to the surgical options, with acceptable post-operative functional results and complication rates when a biological solution or preservation of the wrist joint is not indicated.

Non-invasive expandable prostheses for limb salvage tumour surgery were first used in 2002. These implants allow ongoing lengthening of the operated limb to maintain limb-length equality and function while avoiding unnecessary repeat surgeries and the phenomenon of anniversary operations.

A large series of skeletally immature patients have been treated with these implants at the two leading orthopaedic oncology centres in England (Royal National Orthopaedic Hospital, Stanmore, and Royal Orthopaedic Hospital, Birmingham).

An up to date review of these patients has been made, documenting the relevant diagnoses, sites of tumour and types of implant used. 74 patients were assessed, with an age range of 7 – 16 years and follow up range of 4 – 88 months.

We identified five problems with lengthening. One was due to soft tissue restriction which resolved following excision of the hindering tissue. Another was due to autoclaving of the prosthesis prior to insertion and this patient, along with two others, all had successful further surgery to replace the gearbox. Another six patients required mechanism revision when the prosthesis had reached its maximal length. Complications included one fracture of the prosthesis that was revised successfully and six cases of metalwork infection (two of which were present prior to insertion of the implant and three of which were treated successfully with silver-coated implants). There were no cases of aseptic loosening.

Overall satisfaction was high with the patients avoiding operative lengthening and tolerating the non-invasive lengthenings well. Combined with satisfactory survivorship and functional outcome, we commend its use in the immature population of long bone tumour cases.

Of 3000 patients diagnosed with primary malignant bone tumours and treated at our unit over the past 25 years, 234 (7.8%) were considered to be spindle cell sarcomas of bone (ie not osteosarcoma, chondrosarcoma, Ewing’s, chordoma or adamantinoma). We have analyzed their management and outcomes.

The diagnosis of these cases varied with fluctuations in the popularity of conditions such as MFH, fibrosarcoma and leiomyosarcoma with the passage of time. Treatment was with chemotherapy and surgery whenever possible. 36 patients had metastases at diagnosis and 17 had palliative treatment only because of age or infirmity. The most common site was the femur followed by the tibia, pelvis and humerus. The mean age was 45 and the mean tumour size 10.2cm at diagnosis. 25% of patients presented with a pathological fracture. Chemotherapy was used in 70% of patients the most common regime being cisplatin and doxorubicin. 35% of patients having neoadjuvant chemotherapy had a good (> 90% necrosis) response. The amputation rate was 22% and was higher in patients presenting with a fracture and in older patients not having chemotherapy.

With a mean follow up of 8 years the overall survival was 64% at 5 yrs and 58% at 10 yrs. Adverse prognostic factors included the need for amputation, older age and poor response to chemotherapy as well as a pathological fracture at presentation. The few patients with angiosarcoma fared badly but there was no difference in outcomes between patients with other diagnoses.

We conclude that patients with spindle cell sarcomas should be treated similarly to patients with osteosarcoma and can expect comparable outcomes. The histological diagnosis does not appear to predict behaviour.

Introduction: Giant cell tumor (GCT) is a benign but locally aggressive tumor that primarily affects the epiphyses of long bones of young adults. Pulmonary metastases in giant cell tumor are rare. We report our experience of treating pulmonary metastatic GCT of bone over the last 24 years between 1984–2007.

Methods: A retrospective review of patients’ records and oncology database of patients with metastatic GCT

Results: We had 471 patients with GCT of bone out of which 7 patients developed pulmonary metastases (1.48%). Six patients following diagnosis and initial treatment and one with pulmonary metastases present at the diagnosis. There were 4 males and 3 females aged between 23 to 40 years (median, 27 years). All patients had GCT around the knee (distal femur/proximal tibia). All patients eventually required Endoprosthetic Replacement apart from one who was treated with curettage only. The time of pulmonary metastases from initial diagnosis was 16–92 months (median, 44.6 months). All patients who developed metastases in the postoperative period had thoracotomy for excision of the pulmonary metastases. Two patients received chemotherapy for control of the local recurrence. At an average follow up of 151 months (27–304 months), all patients were alive

Discussion: Pulmonary metastases have been reported as 1% to 9% in GCT. Because of its rarity, very little is known about the long-term outcome and the best treatment for the pulmonary lesions. The mortality rates recorded for patients with pulmonary metastatic GCT range from 0% to 37%. In our series the mortality rate was 0% and metastases 1.48%. It seems that surgical resection of pulmonary metastases gave excellent rate of survival.

Aim: To identify factors leading to the success or failure of extracorporeal irradiation and reimplantation of bone (ECIR).

Method: Review of experience of this technique since 1996 documenting successes and failures.

Results: 35 patients with a variety of malignant bone tumours underwent ECIR from 1996 up to 2007. The most common diagnosis was Ewings’ sarcoma (15) followed by osteosarcoma (9) and chondrosarcoma (5) with the most common sites being the pelvis (15) followed by the tibia (10) and humerus (3). The age range was from 7 to 66 and 8 were skeletally immature at the time of surgery. The bones were sterilised with a dose of 90Gy before reimplantation.

The overall patient survival was 69% at 5 years and 62% at 10 years. Local recurrence arose in 4 cases, 3 of whom already had metastatic disease. None of the LR arose in the irradiated bone. The rate of non union was 9% at the 58 osteotomies, the greatest risk being in the tibia. There were four graft fractures of which 3 needed fixation and all united. There is one case of convincing graft resorbtion after 12 years. Two patients developed infections but there have been none since the done was routinely immersed in antibiotics whilst being irradiated.

Conclusion: ECIR is a useful technique with very limited indications. In the majority of cases it works well. It appears particularly useful in pelvic resections and diaphyseal resections. Distal tibial reconstructions do worst. The irradiated bone needs reinforcing with either cement or a bone graft for best results.

The two week wait has been established as a potential means of diagnosing malignant tumors earlier and thus hopefully leading to improvements in outcome. There remains controversy as to whether these clinic achieve this end or whether they just speed up treatment of patients already diagnosed (eg by imaging)

Aim: The aim of this study is to evaluate the diagnoses of all patient referred with a suspicious soft tissue lump to a two week wait clinic, to assess the diagnostic ‘hit rate’ and how many of these had already had imaging leading to a possible diagnosis of malignancy.

Method: Review of the diagnoses and referral criteria for all patients referred to a soft tissue sarcoma early diagnosis clinic.

Results: ** patients were referred under the 2 week wait criteria with a possible soft tissue sarcoma. ** (**%) turned out to have a malignant diagnosis. Of these, *8 were STS, ** were other soft tissue malignancies and ** were bone malignancices (** being….) Of the patients with a malignant diagnosis, only ** were referred directly to this hospital as a two week wait without previous investigation. Of the remainder *8 had undergone imag-9ing prior to referral leading to a suspicion of malignancy and ** were referred after investigation at another hospital. The average size of STS diagnosed after 2 week wait referral was ** which compared with **cm in those not referred via this route over the same time period.

Conclusion: Patients referred to a soft tissue 2 week wait clinic had a **% risk of malignancy. Of these, ** were new diagnoses suspected purely on clinical as opposed to imaging grounds.

The purpose of our study was to examine the survival and functional outcome of endoprosthetic replacements for non-oncology limb salvage purposes. Although initially designed for bone tumours, such is the versatility of these implants they can be used to salvage failed joint replacements, peri-prosthetic fractures, failed internal fixation and non-union.

Thirty eight procedures were identified from September 1995 to June 2007 from a prospectively kept database, including 17 distal femoral replacements, 12 proximal femoral replacements, 4 proximal humeral replacements, 2 distal humeral replacements, 2 hemi-pelvic replacements and 1 total femoral replacement. The quality of patients’ mobility was used to assess functional outcome and the survival of the prosthesis was calculated using a Kaplan-Meier survival curve.

The Kaplan-Meier implant survival was 91.3% at 5 years, 68.5% at 10 years and 45.7% at 20 years. The limb salvage survival for all reconstructions was 75% at 10 years.

The best survival was as follows pelvic (n=0/2) and total femoral prostheses where there was no failure in either group (n=0/1). Distal femoral replacements survival was 91% at 5 years, a single humeral prosthesis failed at 11 years post surgery, and proximal femoral replacements had a survival at 87.5% at 5 years. Three implants failed, two as a result of infection and required staged revisions and 1 failed as a result of aseptic loosening. Two patients dislocated their proximal femoral replacements, both were treated successfully by closed reduction.

Endoprosthetic replacement appears to be effective and the medium term survival is encouraging. The aim of a pain free functional limb is achievable with this technique. The complication rates are acceptable considering the salvage nature of these patients. We recommend referral of complex cases to a tertiary centre with expertise in this type of surgery.

Endoprosthetic replacement of the pelvis is one of the most challenging types of limb salvage surgery with a high rate of complications. In order to try and decrease the high risk of complications and to allow greater versatility in the reconstruction options, a new concept of pelvic endoprosthesis was developed in 2003. Since then 20 of these ice cream cone pelvic prostheses have been inserted at our centre incorporating antibiotic laden cement around the prosthesis to minimize infection risk.

Aim: To review the outcomes of the ice cream cone prostheses and to learn lessons from this.

Method: retrospective review of records and Xrays of patients having an ice cream cone type prosthesis at our centre.

Results: 20 ice cream cone prostheses were inserted in the past 5 years. Six of the implants were inserted following failure of a previous pelvic reconstruction (one for hydatid disease, one following a excision arthroplasty for chondrosarcoma, three following failed pelvic EPRs). Of the primary tumours, there were 9 chondrosarcomas, 2 Ewings, one each of osteosarcoma, epithelioid sarcoma and GCT. All of the patients had at the least had a P2+P3 resection with most having resection of the ilium above the sciatic notch. The average age of patients at operation was 50.5yrs [range 13–81yrs]. Ten patients (50%) had one or more complication following surgery, of which dislocation was the most common, affecting 5 patients (25%), of whom two have permanent dislocations. Four patients (20%) developed a deep infection of the prosthesis but all had this controlled with early intervention. Two patients (15%) developed a local recurrence, both at the time of widespread metastases. Only one patient has had the prosthesis removed, for severe pain. There were six deaths, four due to metastatic disease and two from cardiovascular complications. The complication was significantly lower for Surgeon A (who did 15 of the 20 procedures).

Conclusion: This method of treatment is still associated with high morbidity but early results are promising. Complications are much lower with increasing experience.

Patients who undergo soft tissue sarcoma excision accumulate serosanguinous fluid, potentially resulting in a seroma. This can lead to wound complications and delay post-op radiotherapy.

The purpose of this preliminary report is to assess the impact of routine application of Tisseel sealant prior to closure.

We investigated whether the sealant Tisseel is effective as a sealing agent to reduce the duration and volume of serosanguinous fluid drainage. Results were compared with individually matched controls.

Patients were split into 2 groups: those receiving 10mls sealant and those not receiving the sealant. Efficacy was evaluated by the number of days required for wound drainage, the volume of fluid drainage and the length of stay compared with matched controls.

The preliminary findings suggest that application of the sealant reduced the duration and quantity of fluid drainage after excision of the STS, allowing earlier discharge from hospital.

We present this work to suggest that the members of the British Orthopaedic Oncology Society should consider using this in a randomised controlled trial setting to evaluate its efficacy nationally.

Chondrosarcoma is treated with respect by oncology surgeons, given that it is relatively resistant to chemotherapy and radiotherapy. The aim was to study the outcomes of surgery for chondrosarcoma and determine the role of initial surgical margins and local recurrence on outcome.

Electronic patient records were retrieved on all patients seen with chondrosarcoma of bone with a minimum of two years follow up. A total of 532 patients were seen with Chondrosarcoma between 1970 and 2006. Patients were excluded if they had initial treatment in another unit (20 patients), a subdiagnosis of dedifferentiated chondrosarcoma (due to very poor prognosis, 43 patients), metastases at presentation (30 patients), if they presented with disseminated metastases prior to local recurrence (12 patients) or were not offered surgery, leaving 402 patients in the study group.

The mean age was 48 years old (range 6–89 years) with the most commonly sites of presentation being in the pelvis in 132 patients (29%), proximal femur in 81 patients (18%), distal femur in 40 patients (9%) and proximal humerus in 40 patients (9%). Grade at presentation was grade 1 in 44%, grade 2 in 44% and grade 3 in 12%. Surgical margins were radical in 3%, wide in 44%, marginal in 29%, planned incisional in 13% and unplanned incisional in 11%. Local recurrence occurred in 87 patients (22%). Local recurrence rates were significantly different for surgical margins on Fisher exact testing (p=0.003), which held true even when stratified by presenting grade of tumour. Surgery for local control was successful in 62% of cases.

Complex relationships exist between surgical margins, local recurrence and survival. Long term survival is possible in 1/3 patients who have local recurrence in intermediate and high grade chondrosarcomas and therefore ever effort should be made to regain local control following local recurrence.
