摘要: 目的 探究间质表型循环肿瘤细胞 (mesenchymal circulating tumor cells, M CTCs) 在结肠癌 (colon cancer, CC) 中的预后价值。 方法 选取2015 年1 月至2016 年6 月在武汉大学中南医院胃肠外科住院治疗 的 115 例 CC 患者为研究对象, 在入院后 24 h 内经外周静脉采取静脉血 2. 5 mL 于 EDTA 抗凝管中, 采用团 队前期自主研发的 CTCBIOPSY ® 设备结合免疫荧光染色 ( immunofluorescence staining, IF) 检测患者外周血 中间质表型 CTCs 的数目, 分析其与患者临床病理因素的相关性; 继而, 采用 Kaplan-Meier 生存曲线和 COX 回归分析方法探究间质型 CTCs 与患者预后的关系。 结果 不同肿瘤位置患者外周血中的间质表型 CTCs 的 数目无明显差异, 而肿瘤低中分化患者外周血中间质表型 CTCs 的数目显著多于高分化患者, Ⅲ期患者外 周血中间质表型 CTCs 的数目显著多于Ⅱ期和Ⅰ期; 进一步分析表明, 间质表型 CTCs 阳性与肿瘤分化程度 (P = 0. 013)、 肿瘤浸润深度 (P = 0. 010)、 淋巴结转移 (P = 0. 043)、 TNM 分期 (P< 0. 001)、 脉管浸润 (P< 0. 001)、 神经侵犯 (P = 0. 004) 以及 CEA 水平 (P< 0. 001) 相关; 生存分析显示, 间质表型 CTCs 阳 性患者的总生存期显著低于阴性者 (χ 2 = 9. 726, P = 0. 002), 且间质表型 CTCs 阳性是影响 CC 患者总生存 期的独立危险因素 (HR = 1. 752, 95 % CI: 1. 104 ~ 3. 871, P = 0. 015)。 结论 结肠癌患者外周血中间质表 型 CTCs 与肿瘤的恶性进展及患者的不良预后密切相关, 有望成为临床预后评估的新型生物标志物。

Abstract: Objective To investigate the prognostic value of mesenchymal circulating tumor cells ( M CTCs) in colon cancer (CC). Methods A total of 115 CC patients hospitalized in the Department of Gastrointestinal Surgery, Zhongnan Hospital of Wuhan University from January 2015 to June 2016 were selected as the research objects. Within the 24 h after admission, 2. 5 mL of peripheral venous blood was administered through peripheral veins into EDTA-containing tube. The number of M CTCs in blood sample was detected by using CTCBIOPSY ® which was previously developed by our team combined with the immunofluorescence ( IF) staining, and the correlation between the number of M CTCs and clinicopathologic factors was analyzed. Furthermore, Kaplan-Meier survival curve and COX regression analysis were used to explore the relationship between M CTCs and patients’ prognosis. Results There was no significant difference in the number of M CTCs in peripheral blood of patients with different tumor locations, but the number of M CTCs in patients with low and middle tumor differentiation was significantly higher than that of patients with high tumor differentiation. Moreover, the number of M CTCs in peripheral blood of patients with stage Ⅲ was significantly higher than that of patients with stage Ⅱ and stage Ⅰ. Further analysis showed that M CTCs positive were correlated with tumor differentiation grade ( P = 0. 013 ), depth of tumor invasion (P = 0. 010), lymph node metastasis (P = 0. 043), TNM stage (P < 0. 001), vascular infiltration (P< 0. 001), nerve invasion ( P = 0. 004) and CEA level ( P < 0. 001). Survival analysis showed that the overall survival time of patients with M CTCs positive was significantly lower than that of patients with M CTCs negative (χ2 = 9. 726, P = 0. 002), and M CTCs positive was an independent risk factor for overall survival of patients with CC (HR = 1. 752, 95 % CI: 1. 104 ~ 3. 871, P = 0. 015). Conclusion Mesenchymal CTCs in the peripheral blood of patients with CC are closely related to the malignant progression of tumors and poor prognosis of patients, which is expected to be a novel biomarker for the clinical prognosis evaluation.
