↵a Data are presented separately for the training and validation sets and also as a single combined cohort for each tumor type. Age and tumor volume are presented as means.
↵b Tumor stage represents the Krouse staging system39 for IP and the American Joint Committee on Cancer staging40 for SCC.
↵c Fisher exact test, P = .578.
↵d Two-sample t test, P = .317.
↵e Two-sample t test, P = .001.
