Rapid on-site evaluation improves fine-needle aspiration biopsy cell block quality.

Introduction: For fine-needle aspiration (FNA) biopsy, the cell block is used for precision ancillary diagnostic tests and personalized molecular evaluation. It is important to maximize quality cell blocks. Rapid on-site evaluation (ROSE) provides specimen adequacy and guides cell block collection.

Effective clinical practices for improved FNA biopsy cell block outcomes.

Background: Cell blocks are critically important in fine-needle aspiration (FNA) biopsies and the increasing requirements for personalized medicine testing further highlight their value. When a cell block is inadequate, it can necessitate additional procedures. The objective of the current study was to measure the impact and outcome of dedicated aspirate pass techniques and slide cellularity on cell block quality.
