- Annotation of tumor and non-tumor regions using QuPath.
- Pixel analysis for quantifying immune cell presence.
- Documentation of findings through spreadsheet records.
Main Results
- Mast cells were predominantly located in the inner margin and peritumor areas.
- CD117, NKp46, and CD1a proteins were observed in various tumor regions.
- Image analysis facilitated accurate quantification of immune cells.
- Findings support the prognostic value of mast cells in HCC.
Conclusions
- QuPath software enhances reproducibility and accuracy in digital pathology.
- Immune cell distribution correlates with prognosis in HCC.
- Further studies are warranted to explore the role of mast cells in cancer.
