Abstract |
Objective A stereotactic biopsy is frequently indicated when considering radiotherapy without an established definitive histopathologic diagnosis. The accuracy of biopsy can be limited; therefore, we used a 5×5×5mm advanced method in our practice. We
aimed to verify the biopsy and cytology results following stereotactic biopsy.
Methods We evaluated the results of stereotactic biopsy and cytology of water used to wash the biopsy tools for 33 brain tumors
that were operated within a 3-year period.
Results The biopsies revealed 8 glioblastomas (cytology results : 2 with malignant cells, 6 without malignant cells), 8 malignant
lymphomas (cytology results : 2 with malignant cells, 3 with benign cells, and 3 without malignant cells), 6 metastases (cytology results : 6 with malignant cells), 2 anaplastic astrocytomas (cytology results : 1 with suspicious cells and 1 with benign cells), 3 lowgrade gliomas (cytology results : 1 with benign cells and 2 whiteout malignant cells), 4 glioses (cytology results : 2 with benign cells
and 2 without malignant cells), and 1 oligodendroglioma. The biopsy sample was lost for 1 patient, but the result of cytology indicated metastatic carcinoma.
Conclusions Stereotactic brain biopsy with tumor cytology using the water used to wash the stereotactic biopsy device could
assist with tumor diagnosis, especially in cases of malignant tumors. |
