Radiotherapy for Lung Metastases in a Patient With Ewing Sarcoma

Abstract

Lung metastases occurred in a young female patient 13 months after finishing combined treatment of a Ewing sarcoma of the left eleventh rib. Primary treatment had included surgical removal, 51 Gy local radiotherapy and chemotherapy.Method. 20 Gy total dose was applied to the lungs of both sides in two courses with an additional 15 Gy to the mediastinum.Results and Discussion.

“…The tumor grading was classified according to the World Health Organization/International Society of Urological Pathology Consensus Classification of Urothelial (Transitional Cell) Neoplasms of the Urinary Bladder, published in 1998. 6 Surgical intervention depended on the characteristics of the patient and aimed at removing the tumor. Six patients underwent transurethral resection of bladder tumor, four patients underwent radical cystectomy, and one patient underwent nephroureterectomy for a renal pelvis tumor.…”

“…MGH-U1 cells were previously established from a bladder tumor 3 , 6 and represent high-grade bladder cancer, whereas MGH-U4 cells were previously derived from a man with bladder carcinoma in situ and severe atypia of the bladder, 3 , 6 and therefore represent low-grade bladder cancer. EST studies were conducted with both MGH-U1 and MGH-U4 cells.…”
