Abstract
AIM: This present study was aimed to compare the role of Oct4 in left-sided colon cancer (LCC) with right-sided colon cancer (RCC). PATIENTS & METHODS: One hundred and fifty one pathology specimens, 68 frozen-thawed tumors and cell lines were used to evaluate the role of Oct4 in LCC and RCC through immunohistochemistry, western blot and real-time quantitative PCR. RESULTS: In LCC, positive expression of Oct4 was positively related to differentiation and Dukes stage (p < 0.01). Only in RCC, Oct4 expression was also positively related to lymphatic invasion and survival rates of 'negative group' were significantly higher. CONCLUSION: In summary, Oct4 was related to tumor differentiation and later Dukes stage in colon cancer, and was correlated with invasion of lymphatic only in RCC. In addition, Oct4 was a potential prognostic indicator in RCC.
