CD68+和CD163+巨噬细胞在口腔鳞状细胞癌中的浸润及作用

摘要

Objective To investigate the correlation between the number of CD68+ and CD163+ macrophages infiltration and the clinical characteristics of oral squamous cell carcinoma (OSCC),and to investigate the role and significance of CD163+ and CD68+ macrophages in OSCC.Methods Forty-two cases of OSCC resected by operation and diagnosed by postoperative pathology with intact clinical data in our hospitals during 2013-2016 were selected.Other 12 cases of oral mamaxillofacial normal tissue served as controls.The number of CD68+ and CD163+ macrophages infiltration in OSCC was detected by immunohistochemistry.Its correlation with clinical characteristics was analyzed.Results The number of CD68+ and CD163+ macrophages infiltration in OSCC was significantly higher than that in the control group (P<0.05);the infiltration quantity of CD68+ and CD163+ macrophages in poor differentiation and moderate differentiation was significantly higher than that in high differentiation(P<0.05).The number of CD68+ macrophages in lymph node metastasis was significantly lower than that without lymph node metastasis (P<0.05).The number of CD163+ macrophages in the lymph node metastasis was significantly higher than that of CD68+ (P<0.05).The number of CD68+ and CD163+ macrophages had positive correlation in OSCC (r=0.48,P=0.00).Conclusion Tumor-associated macrophages (TAMs) and M2 macrophages may play an important role in OSCC,TAMs may inhibits lymph node metastasis in OSCC,while M2 marcophages may promote the lymphatic matastasis of OSCC.%目的 了解CD68+、CD163+巨噬细胞的浸润数量与口腔鳞状细胞癌(OSCC)临床特征的相关性,探讨CD68+、CD163+巨噬细胞在OSCC中的作用及意义.方法 选取贵州医科大学附属口腔医院和贵阳市口腔医院2013-2016年手术切除的,经术后病理确诊,且有完整临床资料的OSCC患者42例,另设12例口腔颌面部正常组织作对照.应用免疫组织化学法检测CD68+、CD163+巨噬细胞在OSCC中的浸润数量,并分析其与OSCC临床特征的相关性.结果 OSCC中CD68+、CD163+巨噬细胞的浸润数量明显高于对照组(P<0.05);CD68+、CD163+巨噬细胞在中低分化的浸润数量明显高于高分化的浸润数量(P<0.05);CD68+巨噬细胞在有淋巴结转移的浸润数量明显低于无淋巴结转移的数量(P<0.05),在有淋巴结转移中CD163+巨噬细胞的浸润数量明显高于CD68+(P<0.05).CD68+和CD163+巨噬细胞在OSCC中的浸润数量呈正相关(r=0.48,P=0.00).结论 肿瘤相关巨噬细胞(TAMs)、M2型巨噬细胞对OSCC具有一定的作用,TAMs可能抑制OSCC的淋巴结转移,而M2型巨噬细胞可能促进OSCC的淋巴结转移.
