Ki67 levels were also heterogeneous, with LI varying from 0% to 30%; the mean LI level was significantly lower in EMRC than in associated neoplasia (mean Ki67 LI: 12.6% vs. 39.2%; p < 0.001); in two cases, the Ki67 LI of EMRCs was equal to or higher than that of the coexistent neoplasia (Figure 3a). The gene discussed is MKI67; the disease is neoplasm.
