[Rhabdomyosarcoma in children].

Issues in diagnosis and complex treatment of pediatric rhabdomyosarcoma were studied in 198 patients with morphologically verified disease. Tumors most often developed in the genitourinary organs (36.6%), head and neck (37%) and--less frequently--on the trunk and extremities (26.4%). The diagnostic workup included instrumental methods, ultrasonography and computed tomography. All modern modalities of cancer treatment, viz. surgery, drug and radiotherapy were used in those patients. As a rule, treatment was either combined or complex. Two-year-survival rate ranged from 83% for rhabdomyosarcoma of the orbit to 50% for those of the trunk and extremities and 47% for head and neck neoplasms. Two-year survival for patients with rhabdomyosarcoma of non-genitourinary sites was 54%.
