[Ultrasound tomography in diagnosis of malignant soft tissue tumors in children]. / Ul'trazvukovaia tomografiia v diagnostike zlokachestvennykh opukholei miagkikh tkanei u detei.

ABSTRACT

Ultrasound findings of 50 children with soft tissue sarcomas of the trunk and limbs were analyzed. There was a high proportion of diagnostic errors (62%), which resulted in the choice of adequate therapeutical measures at early stages of therapy and in advanced disease. The reasons of the errors were as follows nonspecificity of the first clinical manifestations of soft tissue sarcomas; ignorance of instrumental studies that establishes a diagnosis in time; outpatient physicians' unconcern of cancer, misunderstanding of the nontumor nature of disease; no scientifically grounded algorithm of studies. Echographic signs that characterize malignancy, their changes over a therapy, ultrasound pattern due to posttherapeutical changes are considered.
