| Outline of Final Research Achievements |
We previously reported that a carbohydrate determinant, MECA-79, is ectopically expressed in gastric cancer, and is associated with clinical outcomes. The present study attempted to focus on the clinical and functional implication of MECA-79 expression in breast cancer, using breast cancer specimens and breast cancer cell lines, mainly by immunohistochemistry and flow cytometry. Unlike gastric and colorectal cancer, only approximately 5% of breast cancer was considered positive for MECA-79 expression, although MECA-79 expression was occasionally observed in membrane and/or cytoplasm of breast cancer cells. MECA-79 expression was not significantly associated with clinicopatholgical parameters or clinical outcomes in breast cancer. Flow cytometric analysis revealed that cell surface MECA-79 expression was found in none of the 5 breast cancer cell lines. The role of ectopic expression of MECA-79 in breast cancer remains unclear, and further studies would be required.
