However, although only 5 patients presented fibrous tumors, 3 of these (60%) expressed ki67 > 3%, compared to only 5% in the “soft” subgroup (χ2 8.154, p = 0.04, Fig. 5), resulting in a 17-times higher possibility of expressing high ki67 levels (OR 17.500, 95% CI 1.551–197.435). The gene discussed is MKI67; the disease is fibroblastic neoplasm.
