PURPOSE The aim of this study was to evaluate the role of radiotherapy (RT) in the management of Ewing sarcoma family tumors (ESFT). MATERIALS AND METHODS Retrospective analysiswas performed on 91 patientswith localized ESFT treated from 1988 to 2012. Primary tumor size was ≥ 8 cm in 33 patients. Surgery, RT, and combined surgery with RT were applied in 37, 15, and 33 patients, respectively. ...
Supplementary Figure S1: (A) IC50 of proliferation after treatment with Olaparib: 72 hours versus 6 days. (B) Grafic representation of IC50 of ES cell lines after treatment with Olaparib with regard to ES cell lines1q status. (C) Grafic representation of IC50 of ES cell lines with regard to their p53 status.
Ewing's sarcoma (ES) is an uncommon round cell tumor with an aggressive course affecting mainly children and young adults. Only 1% of cases is reported with jaw involvement and have mandibular predilection. Radiographic finding in ES reflect many destructive nature of the lesion, like osteolysis, cortical erosion, periostitis and soft tissue mass. A case of ES of the mandible is reported with s...
Ewing’s sarcoma (ES) is the second most common malignant bone tumor in children and young adults. Most cases are reported in the bone, and extraosseous Ewing’s sarcoma (ESS) is an extremely rare disease. We present a case of 36 year old female with extraosseous Ewing’s sarcoma developing at the soft tissue in the leg. Their diagnosis was radiological and essentially histological. The Treatment ...
Ewing sarcoma-primitive neuroectodermal tumors (ES/PNETs) constitute a family of neoplasms characterized by a continuum of neuroectodermal differentiations. ES/PNET of the uterus is rare. There are 48 cases of ES/PNET of the uterus published in the literature as far as we know. We describe a case of Ewing sarcoma of the uterus occurring in a 17-year-old woman presenting with a two-month history...
Most cases of Ewing's sarcoma are reported in the bone, and extraosseous Ewing's sarcoma is an extremely rare disease. Here, we report a rare case of primary pulmonary Ewing's sarcoma in a patient with hemoptysis. The patient underwent right upper lung lobe lobectomy with adjuvant chemotherapy and radiation therapy and has been free of recurrent disease for 4 years.
Two cases are described in which raised intracranial pressure occurred as a result of superior sagittal sinus (SSS) occlusion by an occipital skull tumour. One was a plasmacytoma, the other a metastatic deposit from a Ewing's sarcoma. The difficulties in diagnosis of this syndrome are illustrated together with the importance and success of appropriate treatment. From the literature it appears p...
A 12-year-old boy presented with primary Ewing's sarcoma of the occipital bone manifesting as intermittent high fever and local pain in the occipital region. Plain skull x-ray films disclosed an unclear lytic lesion in the occipital bone. Computed tomography and magnetic resonance imaging demonstrated the irregularly enhanced mass. The tumor was removed totally. He received intensive chemothera...
Neurofibromatosis type 1 is the most frequent phacomytosis. Patients with neurofibromatosis type 1 (NF1) have a high risk to develop benign or malignant tumors of neurogenic or non-neurogenic origin. The association of (NF1) to low-grade fibromyxoid sarcoma (LGFMS) is very rare. These tumors rarely develop at the skull and have a high incidence of local recurrence and distant metastasis. We rep...
