Summary
Computed tomography (CT)-guided biopsies are safe and effective in pediatric oncology. Cutting needle biopsies offer a higher diagnostic accuracy than fine-needle biopsies, improving patient treatment plans.
Area of Science:
- Oncology
- Radiology
- Surgical Pathology
Background:
- Computed tomography (CT)-guided biopsies are crucial for diagnosis and management across various medical fields.
- This study specifically evaluates the efficacy of cutting needle and fine-needle biopsies in pediatric oncology.
Purpose of the Study:
- To assess the effectiveness of CT-guided cutting needle and fine-needle biopsies in pediatric oncology.
- To compare the diagnostic yield and impact on treatment of these biopsy types.
Main Methods:
- Retrospective analysis of medical records from 75 pediatric oncology patients.
- Evaluation of 101 CT-guided biopsy results, comparing them with clinical follow-up or surgical biopsy.
- Assessing the influence of biopsy outcomes on patient treatment decisions.
Main Results:
- CT-guided biopsies led to treatment alterations in 57 out of 75 patients.
- Both cutting needle and fine-needle biopsies demonstrated comparable ability to obtain adequate tissue samples.
- Cutting needle biopsies achieved a superior rate of specific diagnosis compared to fine-needle biopsies.
Conclusions:
- CT-guided biopsies are a safe procedure with the potential to significantly alter treatment management in pediatric oncology.
- Cutting needle and fine-needle biopsies have distinct optimal applications that should be considered to maximize diagnostic accuracy.
