KIT and neoplasm: At the univariate level (Table 4), shorter DFS was significantly related to non-gastric locations (p = 0.002, Figure 6A) and strongly (all p < 0.001) associated with the presence of epithelioid histology (Figure 6B), increasing tumor sizes, mitotic rates, and risk levels defined by NCCN guidelines (Figure 6C), as well as with 5′ deletion of the KIT exon 11 (Figure 6D).
