ABSTRACT
<p><b>OBJECTIVE</b>To investigate the expression of Ets-1 in gastric carcinoma, para-cancerous tissue and metastatic lymph nodes, and to determine the relationship between Ets-1 expression and clinicopathological features, angiogenesis and survival of patients with gastric carcinoma.</p><p><b>METHODS</b>Gastric carcinoma tissue microarray was used to determine Ets-1 protein expression by SP immunohistochemical staining in 189 advanced gastric cancer, 54 papacancerous tissues, 41 metastatic lymph nodes and 32 control tissues.</p><p><b>RESULTS</b>The positive rates for Ets-1 expression of the carcinoma, paracancerous and control tissues were 71.4%, 29.6% and 18.8%, respectively, with a significant difference among the three groups (P < 0.01). In the cancer tissues, the positive rate of Ets-1 protein expression was significantly associated with depth of invasion and lymph node metastasis (P < 0.01), but not associated with degree of differentiation, Lauren's histological type, sex, age, and size of tumor (P > 0.05). The positive rates for Ets-1 expression of the 41 gastric cancer and 41 metastatic lymph nodes were significantly different (P < 0.05). In metastatic lymph nodes, the positive rate for Ets-1 expression was higher. The MVD in Ets-1 positive tumors was higher than that in the Ets-1 negative tumors, with a significant difference (P < 0.05). Kaplan-Meier survival analysis showed that the survival time of Ets-1-negative patients was longer than that of Ets-1-positive patients (P < 0.05). Cox regression analysis showed that Ets-1 expression was not an independent prognostic factor of gastric carcinoma.</p><p><b>CONCLUSION</b>A higher expression of Ets-1 is involved in carcinogenesis, development, invasion, and metastasis of gastric cancer. Ets-1 plays an important role in angiogenesis in gastric cancer. Ets-1 is a useful marker for predicting the outcome for patients with gastric carcinoma, though it is not an independent prognostic indicator.</p>
