Outcomes of Ewing`s Sarcoma in Patients Admitted to Hospitals of a Medical University in South of Iran
Ewing's sarcoma is a primitive and malignant bone tumor that is a serious medical challenge in preserving the patient's life and choosing the appropriate treatment. The aim of this study was to consider the metastasis and survival rate after preoperative chemotherapy, surgery and postoperative chemotherapy as a treatment protocol.
In this study, 42 patients with Ewing's Sarcoma admitted to Chamran and Namazi Hospitals during 2005 to 2016 were enrolled. After considering inclusion and exclusion criteria, 27 patients were finally entered the study. Neo adjuvant chemotherapy and again restaging with MRI and chest CT scan was done. After restaging, treatment was selected. Treatments included amputation; only wide resection; wide resection and allograft; wide resection and prosthesis and only chemotherapy. After surgical treatments, patient had adjuvant chemotherapy.
In this study, 42 patients were investigated of whom 29 (%69) were male and 13 (%31) female. The age mean and standard deviation were 21.45± 7.69 and 16.23± 4.9 in the male and female in respect. Femur (%30) and tibia (%23.8) were of more involvement respectively. Treatment of 27 patients that was entered to study included amputation (5 subjects), only wide resection (6 subjects), wide resection and allograft (8 subjects) and wide resection and prosthesis (3 subjects). Patients with pelvis involvement received only chemotherapy (5 subjects). 46.2% of subjects had a 5-year survival period.
Early diagnosis of Ewing's sarcoma and appropriate treatment using preoperative chemotherapy followed by, surgery through proper margin removal and then postoperative chemotherapy is highly recommended for this condition. Our study confirmed above result.
