The purpose of this study was to review a large cohort of patients
and further assess the correlation between the histological response
to chemotherapy in patients with Ewing’s sarcoma with the overall
(OS) and event-free survival (EFS). All patients treated for Ewing’s sarcoma between 1980 and 2012
were reviewed. Of these, 293 patients without metastases at the
time of diagnosis and treated with chemotherapy and surgery were
included. Patients were grouped according to the percentage of necrosis
after chemotherapy: Group I: 0% to 50%, Group II: 51% to 99% and Group
III: 100%.Aims
Patients and Methods
Myxofibrosarcoma is described by WHO as comprising of a spectrum of malignant fibroblastic lesions with variably myxoid stoma, pleomorphism and with a distinctively curvilinear vascular pattern. They are reported to be one of the commonest sarcomas of elderly patients. It has previously been reported to have a high rate of locally recurrent disease (50-60%). The aim of the study was to investigate the ROH series of tumours to determine prognostic factors for survival and local recurrence. Patients were identified from the ROH database who had been treated with a new presentation of myxofibrosarcoma. The size, grade and depth of the tumour at presentation was noted. Those patients who had suffered local or distal disease relapse or died were highlighted. Analysis was undertaken by Kaplan Meier survival curves for univariate and cox regression for multivariate analysis.Introduction
