Summary
European laboratories show significant variability in cell block (CB) preparation methods. Low cellularity in cell blocks is the primary challenge, necessitating further research to enhance performance and cellular yield.
Area of Science:
- Cytopathology
- Histopathology
- Laboratory Medicine
Background:
- Cell blocks (CBs) are crucial for cytological sample analysis.
- Numerous methods exist for CB preparation, leading to practice variations.
Purpose of the Study:
- To investigate current cell block preparation practices in European laboratories.
- To identify common challenges encountered in daily cytology practice.
Main Methods:
- An online survey was distributed to European cytology laboratories.
- The survey included 11 questions focusing on CB preparation techniques and issues.
Main Results:
- 402 laboratories responded, revealing diverse CB preparation methods.
- Plasma/thrombin, agar, and commercial kits (Cytoblock, HistoGel, Cellient) are most common.
- Low cellularity (62%) and dispersed cells (22%) are the most frequent issues.
Conclusions:
- Significant variability exists in European cell block practices.
- Low cellularity is the predominant issue, impacting diagnostic quality.
- Further studies are required to optimize CB preparation and improve cellular yield.
