paragraph: Prognostic value of expression of Kit67 , p53 , TopoIIa and GSTP1 for curatively resected advanced gastric cancer patients receiving adjuvant paclitaxel plus capecitabine chemotherapy . To investigate the role of Kit67, p53, topoisomerase II (TopoII) and glutathione S-transferase P1 (GSTP1) in predicting clinical outcome of advanced gastric cancer patients receiving capecitabine plus paclitaxel chemotherapy. ### methodology The clinical data and tissue samples from 136 curatively resected advanced gastric cancer patients receiving capecitabine plus paclitaxel in the third affiliated hospital of Kunming medical university from January 2005 to December 2007 were retrospectively collected and analyzed for Kit67, p53, TopoIIa and GSTP1 expressions by immunohistochemistry. The relationships between expressions of the biomarkers and survival were analyzed. ### results p53 expression were associated with the significantly shorter disease-free survival (DFS) (p<0.001) and overall survival (OS) (p=0.012) in the curatively resected advanced gastric cancer patients receiving capecitabine plus paclitaxel. Kit67, TopoIIa and GSTP1 expressions were not related to DFS and OS. ### conclusions p53 expression positive might predict prognosis in gastric cancer patients who underwent curative surgery followed by adjuvant capecitabine plus paclitaxel chemotherapy. A favorable effect of capecitabine plus paclitaxel might therefore be expected in patients that do not express p53.
