In multivariate Cox regression analysis, absence of CTNNB1 haplotype A-A at rs3864004 and rs4135385 positions and advanced tumor stage were independent poor predictors of patient survival in patients with HCC.

Five carcinomas showed beta-catenin mutations (S37C, T41I, T41A), including 4 (33%) of 12 endometrioid-type tumors and 1 (14%) of 7 mucinous-type tumors.
Heterozygous substitution mutations at codon 37 in two cases (S37F and S37C) and at codon 41 in one case (T41A) were found in three endometrioid lesions (one borderline tumor and two carcinomas) with abnormal beta-catenin expression.
