Research Abstract |
Gastric cancer is representative malignant neoplasm which increases with aging, and its carcinogenesis has been commonly studied based on the histological classification : differentiated type and undifferentiated type. However, gastric cancer often has histologic diversity within the tumor and it is difficult to explain a close relationship between histological classification and carcinogenesis. Therefore, we examined microsatellite instability (MSI) as a marker and found that MSI was significantly related with older age, occurrence in women, papillary adenocarcinoma and solid-type poorly differentiated adenocarcinoma. Unlike colorectal cancer, MSI was not associated with microRNA profile in gastric cancer. This may be due to variety of gastric cancer. Then, we focused on gastric poorly differentiated adenocarcinoma which often occurred in the elderly and found that microRNA profile in solid-type poorly cancer was different from that in nonsolid-type cancer. This result indicated that solid-type cancer may develop in the different way from nonsolid-type cancer.
