YAP1 and neoplasm: In the local cohort, when the YAP nuclear-negative and YAP nuclear-positive groups were compared, the largest basal diameter was significantly smaller in the YAP nuclear-positive group (12.5 ± 2.9 mm vs. 10.9 ± 3.2 mm; P = 0.038; Fig. 2e), whereas the tumor thicknesses were not significantly different between groups (9.5 ± 0.6 mm vs. 9.7 ± 0.5 mm; P = 0.81; Fig. 2f).
