AI-based quantitation of cancer cell and fibroblast nuclear morphology reflects transcriptomic heterogeneity and correlates with survival in breast cancer
SABCS 2022
Study Background
- Morphological features of cancer cell nuclei are routinely used to assess disease severity and prognosis, and prior work has linked cancer nuclear morphology to genomic alterations1-3. In addition, the cellular composition of cancer-associated stroma (CAS) has been linked to prognosis in several cancer types, including breast cancer4.
- Quantitative analyses of 1) nuclear features of cancer cells and other tumor-resident cell types, such as cancer-associated fibroblasts (CAFs), and 2) composition of CAS may reveal novel biomarkers for prognosis and treatment response.
- Here, we applied a nucleus detection and segmentation algorithm, a cell classification model, and a stromal subdivision model to hematoxylin and eosin (H&E)-stained whole slide images (WSIs) of breast cancer specimens, enabling the assessment of features related to nuclear morphology and stromal composition.
