Fine Needle Aspiration/Stereotactic Core Biopsy

ABSTRACT: Fine Needle Aspiration May Shed Breast Cells into Peripheral Blood as Determined by RT-PCR

Objective: A diagnostic test applying reverse-transcriptase chain reaction (RT-PCR) assay targeted against cytokeratin 19 (CK19), cytokeratin 20 (CK20) and the [beta]-subunit of human chorionic gonadotropin ([beta]-hCG) mRNAs was used to evaluate the impact of fine needle aspiration (FNA) on breast cell shedding into peripheral blood.

Conclusion: FNA to breast tumor may cause hematogenous dissemination of breast cells.

Ann's NOTE: What this means is that like a surgical biopsy, it is possible to spread malignant cells through the blood stream by the fine needle aspiration. (NOT GOOD NEWS).
