Outline of Final Research Achievements |
In this study, we investigated the relationship between the CXCR7 expression in tumor blood vessels of oral cancer and clinicopathological factors and prognosis to search the usefulness as a biomarker. CXCR7 expression was analyzed in tumor tissues of oral squamous cell carcinoma and their surrounding non-tumor area by immunohistochemistry. Blood vessels were visualized by CD34 immunostaining in the serial section to investigate the co-localization with CXCR7. CXCR7 was barely stained in blood vessels of non-tumor area, whereas it was stained in tumor blood vessels. The advanced cases were more in CXCR7 high group compared to the low group. Disease-free survival tended to lower in the high CXCR7 group than in the CXCR7 low group. These data suggested that CXCR7 in tumor blood vessels can be a prognosis factor.

Academic Significance and Societal Importance of the Research Achievements |
がんにおけるCXCR7発現については様々ながんで報告されつつあるが、口腔がんにおける腫瘍血管のCXCR7発現の意義についてはまだ報告はない。本研究により,口腔がん腫瘍血管でCXCR7の発現が亢進していること,それがステージなど臨床病理学的因子と関連があることが示唆された.さらに,腫瘍血管でCXCR7発現が高いと局所再発をきたす症例が多く,さらに無病生存率が低い傾向が示された.腫瘍血管におけるCXCR7発現が予後予測などバイオマーカーになり得る可能性が示唆された。
