Area of Science:

  • Neuropathology
  • Oncology
  • Surgical Pathology

Context:

  • Stereotactic biopsy is a minimally invasive technique for obtaining brain tumor samples.
  • Accurate intraoperative diagnosis is crucial for guiding immediate therapeutic decisions.
  • Evaluating stereotactic biopsy material presents unique challenges and potential for diagnostic errors.

Purpose:

  • To assess the efficacy of multistep pathomorphological examination of stereotactic brain tumor biopsies.
  • To compare intraoperative cytological findings with final histological and immunohistochemical results.
  • To determine the diagnostic accuracy and impact of stereotactic biopsy in brain tumor management.

Summary:

  • A study of 260 stereotactic brain tumor biopsies evaluated intraoperative cytology against histological and immunohistochemical analyses.

  • Combining cytological smear and paraffin slide histology achieved a 90.7% accuracy in full pathomorphological diagnosis, including tumor type and malignancy.
  • Intraoperative cytology demonstrated a 76.6% concordance with histological findings and significantly influenced therapeutic strategies.

    • Impact:

    • Stereotactic biopsy, utilizing comprehensive morphological diagnostic techniques, is confirmed as a reliable method for brain tumor diagnosis.
    • The integration of cytological and histological examinations enhances diagnostic certainty and aids in precise tumor characterization.
    • Accurate and timely diagnosis via stereotactic biopsy optimizes patient treatment planning and management.
