Summary of the available data.

Tumour entity	Number of cases	Total number of patches	Number of tumour patches	F1-score (weighted)
SKCM	38	26,746	19,139 (71.6%)	0.87
BRCA	72	2,748	2,308 (84.0%)	0.95
LUAD	39	13,165	4,805 (36.5%)	0.90

The classification performance per tumour entity is reported as weighted F₁-score. The F₁-score is defined as the harmonic mean of precision and recall and ranges between 0 and 1. To account for class imbalances, we compute the weighted average of F₁-scores of both labels, weighted by their support.
