Tumor-associated macrophages (TAMs) play an important role in the progression and prognostication of numerous cancers. However, the role and clinical significance of TAM markers in oral squamous cell carcinoma (OSCC) has not been elucidated. The present study was designed to investigate the correlation between the expression of TAM markers and pathological features in OSCC by tissue microarray. Tissue microarrays containing 16 normal oral mucosa, 6 oral epithelial dysplasia, and 43 OSCC specimens were studied by immunohistochemistry. We observed that the protein expression of the TAM markers CD68 and CD163 as well as the cancer stem cell (CSC) markers ALDH1, CD44, and SOX2 increased successively from the normal oral mucosa to OSCC. The expressions of CD68 and CD163 were significantly associated with lymph node status, and SOX2 was significantly correlated with pathological grade and lymph node status, whereas ALDH1 was correlated with tumor stage. Furthermore, CD68 was significantly correlated with CD163, SOX2, and ALDH1 (P < 0.05). Kaplan-Meier analysis revealed that OSCC patients overexpressing CD163 had significantly worse overall survival (P < 0.05). TAM markers are associated with cancer stem cell marker and OSCC overall survival, suggesting their potential prognostic value in OSCC.
肿瘤相关巨噬细胞(TAM)在多种癌症的进展和预后中发挥着重要作用。然而,TAM标志物在口腔鳞状细胞癌(OSCC)中的作用和临床意义尚未阐明。本研究旨在通过组织芯片研究TAM标志物表达与OSCC病理特征之间的相关性。通过免疫组织化学研究了包含16例正常口腔黏膜、6例口腔上皮发育异常和43例OSCC标本的组织芯片。我们观察到,TAM标志物CD68和CD163以及癌症干细胞(CSC)标志物ALDH1、CD44和SOX2的蛋白表达从正常口腔黏膜到OSCC依次增加。CD68和CD163的表达与淋巴结状态显著相关,SOX2与病理分级和淋巴结状态显著相关,而ALDH1与肿瘤分期相关。此外,CD68与CD163、SOX2和ALDH1显著相关(P < 0.05)。Kaplan-Meier分析显示,CD163过表达的OSCC患者总生存期明显更差(P < 0.05)。TAM标志物与癌症干细胞标志物及OSCC总生存期相关,提示它们在OSCC中具有潜在的预后价值。
