*Staining score of PSMB9/β1i expression and Ki-67/MIB1 expression from results of IHC experiments; -/+1: Partially positive (5% to 10% of cells stained); Focal+2: Focal-positive (focal or sporadic staining with less than 5% of cells stained); +++3: Diffuse-positive (homogenecus distribution with more than 90% of cells stained); -: Negative (no stained cells); U.LANT-like tumour: Uterine Leiomyomatoid Angiomatous Neuroendocrine Tumour-like tumour.
