Immunohistochemical analysis of CDO1 in esophageal cancer tissue microarray with normal tissue controls (ES804).

Expression level was indicated as −, absent or faint expression; +, moderate expression; ++, expression; +++, strong expression.CDO1 positivity (+) was counted in samples with over moderate expression.P values from Fisher’s exact test performed in normal vs. adenocarcinoma, squamous cell carcinoma, or metastatic cancer.*PaNon-malignant normal esophagus tissue and cancer adjacent normal esophagus tissue.蛋白表达水平按如下分级标注：−代表无表达或微弱表达；+代表中等强度表达；++代表阳性表达；+++代表强阳性表达。CDO1阳性（+）的判定标准为中等强度以上表达的样本。采用费希尔精确检验计算正常组织与腺癌、鳞状细胞癌或转移性癌组间比较的P值。*Pa：指非恶性正常食管组织及癌旁正常食管组织。
