  • Title: Computed tomography-guided needle biopsies in pediatric oncology.
    Author: Guimarães AC, Chapchap P, de Camargo B, Chojniak R.
    Journal: J Pediatr Surg; 2003 Jul; 38(7):1066-8. PubMed ID: 12861541.
    Abstract:
    BACKGROUND: The use of computed tomography (CT)-guided biopsies facilitate the diagnosis and management in several medical settings. In this study, the authors analyzed how effective cutting and fine-needle biopsies are in pediatric oncology. METHODS: Medical records of 75 patients were analyzed in retrospect allowing the study of 101 biopsy results. The results of these procedures were compared with clinical follow-up or surgical biopsy results and evaluated for how they affected the patient's treatment. RESULTS: CT-guided biopsies altered the treatment in 57 of 75 patients. No major complication occurred. Cutting and fine-needle biopsies are comparable in obtaining adequate material, but cutting needle obtains a superior rate of specific diagnosis. CONCLUSIONS: CT-guided biopsies are safe procedures that can alter the management of pediatric oncology patients. Cutting and fine-needle biopsies each have one optimal specific use that must be considered to improve their accuracy.
