Immunohistochemistry of serum deprivation‐response protein (SDPR) in clinical endometrioid carcinoma samples. A, Representative immunohistochemically stained images of SDPR and the proportion of positive cases according to histological grade (G1, n = 54; G2, n = 38; G3, n = 34). B, Proportion of positive cases with (n = 30) or without (n = 96) lymphatic invasion. C, Representative immunohistochemically stained image of SDPR with the microcystic, elongated, and fragmented (MELF) pattern and the proportion of positive G1 cases with (n = 11) or without (n = 43) the MELF pattern. Scale bar = 50 μm (A) and 200 μm (C). Student's t test: *P < .05, **P < .01
