Of the studies reporting the prognostic value of positive YAP1 expression for DFS, when stratifying by staining location, both positive overall (nuclear and cytoplasmic) YAP1 expression (HR: 3.733, 95% CI: 1.469–9.483, p = 0.001) and positive nuclear YAP1 expression (HR: 1.481, 95% CI: 1.163–1.886, p = 0.554 without heterogeneity) indicated worse cancer DFS. The gene discussed is YAP1; the disease is cancer.
