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. The distance (mm) and tissue has been regularly reported for 5 years, prior to this it was reported as wide, marginal or intra-lesional. It is known from previous studies that 90% of locally recurrent disease for osteosarcoma and Ewing's 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, giving at least 2 years follow up. The pathology records were reviewed and 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
Methods
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. 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
