Content
The Post-NAT-BRCA dataset is composed of:
• 96 whole slide images stored in an uncompressed .svs file format, standard for pathology slides. Slides were scanned at 20x objective on an Aperio slide scanner at Sunnybrook Health Sciences Centre.
• An Excel (.xlsx) file containing clinical features for each patient including age, treatment, ER/PR/HER2 status etc. A key and detailed description of each column is provided in a separate tab titled "Definitions". Each row in the spreadsheet corresponds to a single (.svs) slide and anonymised patient ID's are provided in a separate column.
• Manual annotations of tumor cellularity and cell labels, provided as Sedeen annotation files (.xml). Annotations are given in two directories, where the "WSI_train" folder contains WSIs annotated by a single rater and "WSI_test" was annotated by two raters.
Recommended Software
To browse whole slide images and annotations, we highly recommend you use Pathcore's Sedeen Viewer which is available for free: https://pathcore.com/sedeen/
Please ensure that the "sedeen" folder is unzipped and placed into the same folder containing the .svs files. Sedeen Viewer loads annotations from this folder automatically when images are opened.
Upon opening WSIs in Sedeen, you will notice that annotations have been color-coded according to the following key:
- Pink: Healthy (0% tumor cellularity)
- Blue: Low tumor cellularity (0 - 30%)
- Yellow: Medium tumor cellularity (31 - 70%)
- Green: High tumor cellularity (70 - 100%)
- White: Contains annotations at the cell level and labeled as:
- Lymphocyte: TIL-E, TIL-S
- Normal Epithelial: normal, UDH, ADH,
- Malignant Epithelial: IDC, ILC, Muc C, DCIS 1, DCIS 2, DCIS 3, MC- E, MC - C, MC - M
