ABSTRACT

Objective EpCam and Wnt/ β-catenin pathway in colon carcinoma and its clinic-pathological significance of the distribution,studying the relationship between EpCam and Wnt / β-catenin.Methods Retrospective analysis detected by immunohistochemistry 60 cases of colon cancer,20 cases of adjacent atypical hyperplasia,60 normal colon tissue EpCam and Wnt / β-catenin protein expression.Results (1)normal colon tissue,cancer tissue and cancer tissue showed positive expression EpCam clear upward trend,were 23.5%,62.3%,96.5% ; with normal colonic mucosa to cancer transformation,β-catenin in the membrane expression of the positive rate decreased,while the cytoplasm is followed by increased expression rate in poorly differentiated carcinoma or even nuclear expression,EpCam strong positive expression of Wnt / β-catenin cytoplasmic-positive rate of histological type,depth of invasion,lymph node metastasis; (2)the EpCam with the Wnt / β-catenin expression showed a positive correlation (r =0.653,P <0.05) ;(3)high expression EpCam and Wnt / β-catenin in patients with colon significant increase in cancer recurrence rate and 5-year survival rate was significantly reduced.Conclusion EpCam and Wnt / β-catenin pathway in colon cancer positively is correlated,EpCam and Wnt / β-catenin is connected with high expression and tumor invasion,metastasis and prognosis.

ABSTRACT

Objective To discuss the influence of the progress and result in gastic cancer operation through application of neo-adjuvant chemotherapy in multi-disciplinary team (MDT).Methods Clinical data of the patients treated in MDT model 45 cases and non-MDT model(78 cases) were respectively analyzed,and the index about pathologic change,histologic transform and operative result between the two groups were compared.Results In the index of pathologic change,the incidence of abdominal adherence and ascites and pyloric obstruction in MDT model group were obviously less than non-MDT model group( P <0.05 ).In the index of histologic transform,texture of mesentery in MDT model group was more fragile than non-MDT model group( P <0.05).In the index of operative results,the operative duration and intra-operative bleeding in MDT model group were less than non-MDT model group (P <0.05).Conclusion Neo-adjuvant chemotherapy has certain influence in gastric caneer operation,but the successful operations were performed by standard and correct procedures.Therefore,optimizing combined therapy in MDT model and constructing preoperative evaluation system with neo-adjuvant chemotherapy.

ABSTRACT

Objective To investigate the expressions and clinical pathological significance of EpCAM and the β-catenin pathway in colon cancer,and the correlation between EpCAM andβ-catenin.Methods Immunohistochemistry was used to detecte the expressions of EpCAM and β-catenin proteins in colon cancer tissues and corresponding adjacent tissues of 70 cases of colon cancer patients,the clinical and pathological features of colon cancer and their relationship were retrospective analyzed.Results ①EpCAM and β-catenin protein expressions in colon cancer tissue was 52 cases (74.3%) and 55 (78.6%) positive respectively; EpCAM and β-catenin proteins in cancer adjacent tissues in 13 cases( 15.7% ) and 9 cases ( 12.9% ) were positive,the differences were statistically significant.②the EpCAM expression is positively correlated with the β-catenin expression ( r =0.616,P < 0.01 ).③The expressions of EpCAM and β-catenin correlated with the tumor differentiation,invasion depth,lymph node metastasis and TNM staging related ( P < 0.05).Conclusion EpCAM and β-catenin pathways in colon cancer positively correlate,and closely correlate with colon cancer.The expression level of EpCAM and β-catenin can be used as a reference for the colon disease course and healing.
