Pijnenborg et al.3 found nuclear accumulation of beta-catenin in 38% of their endometrioid endometrial cancer cases, while Kariola et al. found 53% and Schlosshauer et al. found 47%.4,5 On the other hand, we found no difference in beta-catenin expression between cases of atrophic endometrium and endometrial cancer, since both groups stained almost equally in the cytoplasm. Here, CTNNB1 is linked to endometrial cancer.
