They are overlapping entities with the same histological origin but different degree of neuroectodermal differentiation (absent for ES, definite for pPNET). (surgicalneurologyint.com)

Tumors may occur at any age, but many specific tumors have a particular age group in which they are most common. (indiasurgerytour.com)

The tumor will then need to be biopsied to confirm the diagnosis. (wikipedia.org)
According to diagnosis, specific therapy was performed in 35% of patients: 17% underwent microsurgical removal, and 18% underwent chemotherapy or radiotherapy. (thejns.org)

For recurrent tumors, surgery combined with radiotherapy, chemotherapy, and/or targeted therapy can be used for control. (bvsalud.org)
The patient opted for conservative treatment with chemotherapy over hemipelvectomy. (jbstjournal.com)
Treatment involves maximal safe tumor resection, craniospinal irradiation, and high-dose chemotherapy. (biomedcentral.com)
Although applying multi-modal therapies (radiation, chemotherapy, and surgery) has increased 5-year survival amongst standard-risk MB patients, overall survival (OS) rates seem to have plateaued. (biomedcentral.com)
The patient underwent gross total resection with adjuvant chemotherapy and radiation. (surgicalneurologyint.com)
The current European Ewing tumour Working Initiative of National Groups 1999 (EURO-EWING 99) study has enrolled over 3,200 patients in a study evaluating an intensive induction regimen (VIDE, vincristine, ifosfamide, doxorubicin and etoposide) and, in selected cohorts of randomized patients, high dose chemotherapy with stem cell rescue. (biomedcentral.com)

We studied 5 consecutive cases of GCT involving the distal radius operated by en-bloc resection of tumor followed by reconstruction with ipsilateral non-vascularized fibular graft with a minimum 1 year follow-up. (jbstjournal.com)
Once the patient was medically fit, surgery (ORIF with resection of distal end of radius and reconstruction with ipsilateral non vascularised proximal fibula along with plate and 2 k-wires) was performed. (jbstjournal.com)

DSRCT was first described by Gerald and Rosai in 1989 as a primitive neoplasm of children and young adults that most frequently occurs in the serosa of the pelvic cavity. (medscape.com)
This schedule of VDC/IE is feasible in patients with EFT and DSRCT including adults and those with metastases. (biomedcentral.com)

To evaluate tolerability and maintenance of dose intensity of 2 weekly treatment with vincristine, doxorubicin, cyclophosphamide alternating with ifosfamide, etoposide (VDC/IE) in patients with advanced small round cell sarcomas including Ewing family tumours (EFT), desmoplastic small round cell tumours (DSRCT) and undifferentiated high grade round cell sarcomas (UHGRCS). (biomedcentral.com)
A total 193 cycles of VDC/IE were administered to 10 patients with EFT, 4 with DSRCT and 2 with UHGRCS. (biomedcentral.com)

The tumor was soft and moderately vascular. (surgicalneurologyint.com)

The most common combination- EWS exon 7 fused to FLI1 exon 6 (type 1 translocation)-occurs in approximately 50-64% of tumors of Ewing sarcomas. (medscape.com)
The most common translocation seen in about 85% of all Ewing tumor is the t(11;22) translocation. (medscape.com)
The tumor is more common in males than females (3). (pediatriconcall.com)
Juxta-articular giant cell tumors of the lower end radius are common and present a special problem of reconstruction after tumor excision. (jbstjournal.com)
RP masses are quite common in paediatric patients and more than one diagnostic modality is required to identify and diagnose them. (waocp.com)
Common non-epithelial neoplasms that may cause malignant effusions include malignant melanoma, sarcomas, and other neoplasms including germ cell tumors [ Figure 1 ]. (cytojournal.com)
