The task is to decide the Hallmarks of Cancer (HOC) taxonomy of the article based on its abstract. The input is an abstract text. There are 10 topics you will need to decide whether the article is related to. Topics: sustaining proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, activating invasion and metastasis, genomic instability and mutation, tumor promoting inflammation, cellular energetics, avoiding immune destruction. The output should be topics from the above 10 topics, that are related to the input article. Please note one article can be related to multiple topics. Output format: provide a semicolon-separated list of relevant topics.

    INPUT: BACKGROUND &amp ; OBJECTIVE Altered cell adhesion has a critical role in the development of epithelial cancers . E-cadherin act on the maintenance of cell-cell adhesion and its function was thought to be regulated by associated cytoplasmic proteins , such as alpha-catenin and beta-catenin . This study was designed to examine the expression of beta-catenin in gastric carcinoma and to determine the relationship between tumor characteristics and survival . METHODS Immunohistochemical staining of beta-catenin and E-cadherin was performed in 148 patients with gastric carcinoma . RESULTS Abnormal expression of beta-catenin and E-cadherin was performed in 148 patients with gastric carcinoma . RESULTS Abnormal expression of beta-catenin and E-cadherin was demonstrated in 43.2% and 44.6% of tumors respectively . Up to 63% of tumors stained abnormally for one or two components of the cadherin-catenin complex ( beta-catenin , E-cadherin ) . Abnormal beta-catenin and E-cadherin staining occurred more frequently in poor differentiated tumor than in good differentiated tumors ( P &lt ; 0.005 , respectively ) . There was a significant correlation between abnormal beta-catenin expression and depth of invasion(P &lt ; 0.025 ) . Moreover , abnormal beta-catenin expression was more frequent in tumors with positive lymph node metastasis ( 45/84 , 53.6% ) and distance metastasis(21/31 , 67.7% ) than in tumors without lymph node metastasis ( 19/64 , 29.7% ) ( P &lt ; 0.005 ) and distance metastasis ( 43/117 , 36.8% ) ( P &lt ; 0.005 ) . A survival advantage was noted in tumors retaining normal membranous expression of beta-catenin , independent of type , grade , or stage ( P &lt ; 0.005 ) . CONCLUSIONS Abnormal expression of the E-cadherin-catenin complex occurs frequently in gastric carcinoma . The close correlation with poor survival suggests that abnormal beta-catenin may be a useful prognostic marker .
