| Outline of Final Research Achievements |
In the patients who underwent curative resection, IL-17 mRNA expression levels in peritoneal lavage increased according to the depth of tumor invasion.
To examine the correlation of IL-17 production between in peritoneal lavage and in the primary tumor tissue, we performed immunohistochemical staining for IL-17 of primary tumor in the same patients samples. In the primary tumor tissues, IL-17 immunoreactive cells were detected at the cytoplasm in mononuclear cells; however none of the tumor cells were stained for IL-17. IL-17 producing cells in tumor tissues were 7.30 ± 0.82 (mean ± SE) per field. There were no correlation between IL-17 positive cells in tumor tissues and IL-17 mRNA expression in peritoneal wash (r=0.092, p=0.329). It was suggested that IL-17 locally expressed in the tumor would be a potential therapeutic target for treatment of patients with advanced gastric cancer.
