Resection of the Post-chemotherapy Tumour Volume without (Neo)Adjuvant Radiotherapy Does Not Increase the Risk of Local Recurrence in Ewing Sarcoma
Description
In this presentation, Dr. Ibe discusses the surgical management of Ewing sarcoma, a common type of malignant bone tumor, particularly focusing on the resection of post-chemotherapy tumor volumes without radiation. He emphasizes that this approach does not lead to increased local recurrence rates in patients. Dr. Ibe reviews the survival statistics for Ewing sarcoma, which show a 65%-80% survival rate at five years, diminishing to 25%-40% at ten years. With local recurrence in some cases reaching 25%, he examines various treatment strategies that combine chemotherapy and surgery, with or without radiation.
He outlines a study where outcomes were assessed by analyzing a prospective database of patients treated for Ewing sarcoma, evaluating factors such as tumor margins and necrosis percentage. Findings indicated a total of seven local recurrences out of 65 patients, with some associated complications from radiation therapy, such as wound complications and secondary sarcomas.
Dr. Ibe concludes that resecting the post-chemotherapy volume in patients with extremity Ewing sarcoma without adjunctive radiation therapy does not correlate with an increased risk of local recurrence. He calls for further studies, especially targeting pediatric populations, to explore long-term outcomes and complications.
