BackgroundThis study evaluated the expression of p300 in colorectal cancer, its relationship with clinicopathological characteristics, and its potential prognostic significance. MethodsThe expression of p300 was measured using immunohistochemistry in tumors and surrounding normal mucosa from 199 patients with primary colorectal cancer. The patients were followed for a median period of 83 months. ResultsNuclear p300 expression was significantly associated with histology (P=0.031) and lymph node involvement (P=0.019). When the low and high p300 groups were subdivided according to tumor location, the disease-free survival rate differed only for the patients with colon cancer (P=0.008). In addition, the disease-free survival significantly differed with p300 expression for stage II disease (P=0.038), but not for stage III disease. Multivariate analysis revealed that lymph node involvement (P=0.014) and p300 expression (P=0.032) were independent predictors of overall survival in adenocarcinomas. ConclusionThe overexpression of p300 may be an independent favorable prognostic factor for disease-free survival in patients with colorectal cancer. J. Surg. Oncol. 2013; 108:374-377.
