Askin tumor

Ewing's Sarcoma Family Tumors (ESFT) include classic Ewing's sarcoma of bone, extra-skeletal Ewing's sarcoma (EES), malignant small cell tumor of the chest wall (Askin tumor), and soft tissue-based Peripheral Primitive Neuroectodermal tumors (pPNET). The t(11;22)(q24;q12) translocation is associated with 85% of tumors and leads to EWS-FLI-1 (Ewing's Sarcoma-Friend Leukemia Integration-1) formation. This is a potent transforming gene that encodes a chimeric protein that plays a role in the genesis of Ewing's Sarcoma and Primitive Neuroectodermal Tumors...

BACKGROUND: Resistant starches (RSs) are not digested by human digestive enzymes and pass through the upper digestive tract to become substrates for colonic bacteria. Resistant starch supplementation has shown promising results in altering the microbiota of animal models of chronic kidney disease (CKD). Resistant starch consumption may influence the production of uremic toxins in CKD. OBJECTIVE: To conduct a systematic review to determine whether the consumption of RS reduces the progression of kidney disease in adult patients with CKD...

Ewing sarcoma is a primitive neuroectodermal tumor which seldom presents with primary disease in people over age 40 and outside of the appendicular or axial skeleton. We examine a case of primary thoracic Ewing Sarcoma diagnosed initially by CT-guided biopsy in a woman at the age of 74 years. The disease progressed after initial combined modality therapy consisting of neoadjuvant chemotherapy, surgical resection, and adjuvant radiation therapy and two additional courses of multiagent chemotherapy. After relapse of her disease, subsequent second- and third-line systemic agents which included chemotherapy and targeted agents were given with disease stabilization achieved now over 30 months from initial diagnosis...

DEK::AFF2 carcinomas of the head and neck region have been recently described and reported to have aggressive clinical behavior but exceptional sensitivity to immunotherapy. We report a case of a 26-year-old female, never smoker, with a 5.2-cm left lower lobe central lung mass, with morphologic features identical to those reported for DEK::AFF2 head and neck carcinomas, including mixed papillary exophytic and invasive components, squamous/basaloid features, and monomorphic cytomorphology. DEK (exon 7)::AFF2 (exon 9) fusion was identified by whole-transcriptome RNA sequencing...

Ewing's sarcoma (ES) is a small round cell sarcoma arising in the bone or soft tissue. Ewing's sarcoma/primitive neuroectodermal tumours (PNET) of the thoracopulmonary region is called Askin's tumour. The common clinical presentations described for this extrapulmonary tumour are fever, chest wall mass with or without pain, dyspnea, and cough. Very few cases of Askin's tumour have been reported with haemoptysis as the initial presentation, which is usually a presentation of intrapulmonary lesions. A 22-year-old male presented to the emergency department with complaints of haemoptysis, mild chest pain, and swelling on the right side of the chest wall...

Ewing's sarcoma family of tumors (ESFTs) contains multiple tumors with similar histological and immunohistochemical features. ESFTs are small, round cell, highly malignant tumors that arise from the neuroectoderm of bone and extraskeletal soft tissue. Ewing's sarcoma is the second most common primary malignant bone cancer in children and adolescents, with the second decade of life being the most common age of diagnosis. In this article, we present a case of a young male who presented to the emergency department complaining of shortness of breath and cough and was later diagnosed with Ewing's sarcoma of the chest wall, which is also called Askin's tumor, and it is an extremely rare disease with only 17 cases reported in the literature...

The aim of the study was to show principles of diagnosis and treatment of Askin's tumor in children. Diagnostic procedures include physical examination, chest X-ray, CT scan and PET CT, morphological, histological and immunohistochemical examinations, cytogenetic study. Primitive neuroectodermal tumors belong to the group of low differentiated, overly aggressive neoplasms, originating from cells of the parasympathetic autonomic nervous system. Patient F., 9 years old, first consulted by pediatric oncologist in 2014 with complaints of volume formation in the chest on the right side which progressively increases...

Ewing sarcoma is typically seen in children involving long bones. Although well described, its presentation in extraskeletal tissues is relatively rare and is classified as an Ewing sarcoma family of tumors. They are mostly curable when they occur in children. An extraskeletal Ewing sarcoma in adults is uncommon, limiting the experience in adult oncologists. The biopsy is essential for definitive diagnosis, which shows small round blue cells that must be differentiated from lymphoma, embryonal rhabdomyosarcoma, and small cell carcinoma...

PURPOSE: To evaluate the diagnostic performance of LI-RADS treatment response algorithm (LR-TRA) and modified RECIST (mRECIST) for the detection of viable hepatocellular carcinoma (HCC) on MRI after trans-arterial chemoembolization (TACE). MATERIALS AND METHODS: This retrospective study includes cirrhotic patients that underwent trans-arterial chemoembolization prior to liver transplantation from 2013 to 2017 with a pre- and post-treatment MRI available. Three blinded readers assigned a LR-TRA and mRECIST category to each lesion...

Primary spinal extradural Ewing's sarcoma/primitive neuroectodermal tumor (PNET) is rare malignant tumor of childhood and early adulthood. The World Health Organization classifies PNET as an undifferentiated round cell tumor arising from primitive neuroepithelial cell. It can be central or peripheral PNET depending on site of presentation. Usually, the presenting symptoms are chronic back pain and myelopathy. Overall prognosis and survival are dismal in spite of total surgical resection and adjuvant therapy...

OBJECTIVE: Although extensive analyses evaluating screening mammography for breast cancer have been published, some utilized databases do not distinguish between modes of detection, which confounds the conclusions made about the impact of screening mammography. METHODS: A retrospective cohort study of women at our institution with pathologically-proven breast cancer from January 2015 to April 2018 was conducted. Subjects were categorized by their mode of diagnosis: screening or non-screening...

A 53-year-old male with no significant past medical history presented with an acute traumatic fracture of his thumb. Preoperative chest radiograph before K-wire fixation demonstrated an incidental 9 cm opacity of the left lung. Chest computed tomography revealed a 6.3 cm aggressive appearing pleural-based mass with erosion and destruction of the underlying rib. The patient underwent percutaneous biopsy with interventional radiology, and pathology revealed a small round blue cell tumor with positive CD99 staining and a FUS-ERG chromosomal translocation...

BACKGROUND: Women should be evaluated for breast cancer risk by age 30 to assess for screening need. Recent trends in breast cancer in this population may further inform recommendations. OBJECTIVE: The aim of this study was to analyze trends over time in the rate of breast cancer, tumor characteristics and treatment in women under age 40. METHODS: Retrospective cohort study of women under age 40 at our institution diagnosed with breast cancer from January 2007 to April 2018 was conducted...

Introduction: Ewing sarcomas of the chest wall, historically known as "Askin tumors" represent highly aggressive pediatric malignancies with a reported 5-year survival ranging only between 40 and 60% in most studies. Multimodal oncological treatment according to specific Ewing sarcoma protocols and radical "en-bloc" resection with simultaneous chest wall repair are key factors for long-term survival. However, the surgical complexity depends on tumor location and volume and potential infiltrations into lung, pericardium, diaphragm, esophagus, spine and major vessels...

Askin's tumor is a kind of aggressive tumor and extremely rare. To date, the treatment is uncodified and the prognosis for patients with this tumor remains bleak. Herein we report a case of a giant Askin's tumor in the chest wall that following diagnosis was successfully treated with surgical resection.

BACKGROUND: Breast cancer has traditionally been considered to have a low immunogenic potential compared to other tumor entities. SUMMARY: The most extensively studied immunotherapeutic agents for breast cancer to date are immune checkpoint inhibitors, with the results of the IMpassion130 trial leading to the approval of atezolizumab plus nab-paclitaxel for first-line treatment of programmed cell death ligand 1-positive, metastatic, triple-negative breast cancer, and studies in earlier stages have yielded promising results...

PLACE AND DURATION OF STUDY: Department of Gastroenterological Surgery, Kartal Koşuyolu High Specialty Training and Research Hospital, between November 2006 and December 2018. METHODOLOGY: A retrospective review was made of 252 patients; and the clinicopathological characteristics and survival status in the presence of T1-T2 and T3-T4 patients were investigated...

Askin tumor (a Ewing sarcoma variant) is the most common tumor of the chest wall in the pediatric age group. Multimodal treatment is required, with complete resection being the cornerstone of effective management. We describe the case of a 13-year boy with a left paraspinal Ewing sarcoma with intraspinal extension and spinal cord compression with neurological weakness. He underwent complex surgical resection using thoracoscopic resection of multiple ribs along with vertebral resection and reconstruction, after neoadjuvant therapy...
