摘要: 目的:探讨口腔鳞状细胞癌(oral squamous cell carcinoma, OSCC)患者与外周血循环肿瘤细胞(circulating tumor cells, CTCs)的上皮-间充质转化(epithelial-mesenchymal transition, EMT)状态的关系。方法:采用CanPatrolTM CTC-二代捕获技术联合RNA多重原位杂交分析(RNA in situ hybridization, RNA-ISH),检测32例OSCC患者术前1 d外周循环血中的肿瘤细胞。CTCs将根据EMT的相关标志物进行分型鉴定。结果:根据EMT相关标志物的表达情况,将检测出的CTCs分为上皮型CTCs(epithelial CTCs, e-CTCs),混合型CTCs(epithelial-mesenchymal-mixed CTCs, mix-CTCs)及间质型CTCs(mesenchymal CTCs, m-CTCs)。CTCs总数为198,其中e-CTCs为56(28.3%),mix-CTCs为128(64.6%),m-CTCs为14(7.1%)。每位患者的CTCs平均数值为(6.19±6.07),其中包括e-CTCs为(1.75±1.91),mix-CTCs为(4.00±5.77)和m-CTCs为(0.44±0.63)。CTCs总体数值与mix-CTCs数值相关(r2=0.908,P<0.001)。e-CTCs数值与淋巴结有无转移(r2=0.278,P<0.05)和TNM分期(r2=0.278,P<0.05)相关。CTCs总体数值与患者术后发生复发或转移(r2=0.252,P<0.05)相关。结论:mix-CTCs和e-CTCs数值可能对OSCC的进展其重要作用,CTCs可能作为OSCC预测预后的潜在指标。

Abstract: Objective: To investigate the correlation between the status of epithelial-mesenchymal transition (EMT) of circulating tumor cells (CTCs) and oral squamous cell carcinoma (OSCC). Methods: CanPatrolTM CTC-enrichment and situ hybridizatio (ISH) were used to isolate, identify, and classify CTCs from blood of 32 OSCC patients. Blood was collected from OSCC patients at 1 day before operation. CTCs were identified and characterized according to the EMT markers. Results: CTCs were classified into three subpopulations based on EMT markers: epithelial CTCs (e-CTCs), epithelial-mesenchymal-mixed CTCs (mix-CTC), and mesenchymal CTCs (m-CTCs). Total 198 CTCs were detected in all patients: 56 (28.3%) CTCs of them were e-CTCs, 128 (64.6%) were mix-CTCs, and 14 (7.1%) were m-CTCs. The average number of CTCs from each patient was 6.19±6.07 which included 1.75±1.91 of e-CTCs, 4.00±5.77 of mix-CTCs, and 0.44±0.63 of m---CTCs. The number of total CTCs was correlated with the number of mix-CTCs (r2=0.908, P<0.001). The number of e-CTCs was correlated with lymph node metastasis (r2=0.278, P<0.05) and TNM stage (r2=0.278, P<0.05) in this study.The number of total CTCs was correlated with recurrence or metastasi (r2=0.252, P<0.05). Conclusion: Mix-CTCs and e-CTCs might play an important role in the progression of OSCC, and the number of CTCs in OSCC might have the potential to be a predictor of prognosis.
