Oral Squamous Cell Carcinoma(OSCC), CD109, Immunohistochemistry, Metastasis


The purpose of this study was to investigate the expression of CD109 and its clinicopathological significance in oral squamous cell carcinoma. Data from TIMER2.0 and UALCAN were analyzed to assess CD109 mRNA levels in OSCC. The immunohistochemical method was used to investigate the expressions of CD109 in 20 normal oral mucosa and 75 OSCC and analyzed the relationship between the expression of CD109 and the clinical variables. The mRNA levels of CD109 in OSCC tissues were significantly higher than in adjacent normal tissues (p<0.05). Immunohistochemical analysis revealed that CD109 protein expression was increased in OSCC tissues compared to normal tissues, and this difference was statistically significant (P<0.05). The positive rate of CD109 expression was 94% (16/117) in the group with lymph node metastasis, while it was 55% (32/58) in the group without metastasis (P<0.05). Similarly, the positive rate of CD109 expression was 91% (22/23) in the low differentiation group and 59% (26/52) in the high differentiation group (P<0.05). CD109 expression is markedly higher in OSCC, contributes to the pathological grading of OSCC and predicts lymph node metastasis.
