客观的。趋化因子受体 CXCR4 及其配体 CXCL12 已被认为在癌症的发生或进展中发挥重要作用。本研究的目的是调查口腔癌前病变和口腔鳞状细胞癌 (OSCC) 中 CXCL12/CXCR4 的变化。方法。通过免疫组织化学方法评估 13 例正常口腔上皮、24 例发育不良口腔白斑 (OLK) 和 40 例 OSCC 标本中 CXCL12 和 CXCR4 的表达。结果。 CXCR4 在 37.5% 的 OLK 和 60% 的 OSCC 中表达。 CXCL12 在 50% 的 OLK 和 62.5% 的 OSCC 中检测到。 OLK中CXCR4阳性率与正常上皮无显着差异,但CXCL12阳性率明显较高。在 OLK 和 OSCC 中均发现 CXCL12 和 CXCR4 之间存在显着相关性。结论。我们的结果表明CXCL12/CXCR4轴可能在口腔恶性转化的早期阶段发挥作用,并促进口腔癌发生的进展。
Objective. The chemokine receptor CXCR4 and its ligand CXCL12 have been suggested to play important roles in the initiation or progression of cancers. The goal of the present study was to investigate alterations of CXCL12/CXCR4 in oral premalignant lesions and oral squamous cell carcinoma (OSCC). Methods. In 13 normal oral epithelia, 24 dysplastic oral leukoplakia (OLK), and 40 OSCC specimens, expressions of CXCL12 and CXCR4 were evaluated by immunohistochemistry. Results. CXCR4 was expressed in 37.5% of OLK and 60% of OSCC. CXCL12 was detected in 50% of OLK and 62.5% of OSCC. In OLK, CXCR4 positive ratio showed no significant difference from normal epithelia, but the CXCL12 positive ratio was significantly higher. Significant relationship between CXCL12 and CXCR4 was found both in OLK and OSCC. Conclusion. Our results indicated that CXCL12/CXCR4 axis may play roles from early steps of oral malignant transformation and contribute to the progress of oral carcinogenesis.
