To identify factors leading to the success or failure of extracorporeal irradiation and re-implantation of bone (ECIR). Review of experience of this technique since 1996 documenting successes and failures.Aim
Method
The aim of this study was to investigate the results of a series of cases from a single institution with respect to local disease control and patient survival to determine prognostic factors. Electronic patient records were reviewed on all patients with STS between February 1963 and January 2007. 2445 patients had over 30 types of STS. 1639 (67%) had not received any treatment prior to presentation, however, 770 patients (32%) had undergone a previous attempted excision. Survival analyses were done using Kaplan Meier and Cox regression analyses, however, for prognostic factor analysis, only patients presenting without prior treatment were included.Introduction
Methods
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. 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. 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 amputationMethod
Results
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. 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
