目的 了解结肠癌患者循环肿瘤细胞(CTCs)与临床病理分期之间的相关性。方法 应用Cell Search 技术检测未经治疗的结肠癌患者外周血中CTCs数量,并观察与临床病理分期的相关性。结果 在32例首诊为结肠癌患者中,术前外周血检出CTCs阳性13例,阳性率40.6%;CTCs阳性率与患者年龄、性别、肿瘤大小、神经侵犯无关;与结肠癌浸润深度、TNM分期、脉管侵犯相关(P<0.05),TNM分期高(Ⅲ+Ⅳ)患者的CTCs阳性率显著高于TNM分期低(Ⅰ+Ⅱ)患者(P<0.05)。结论 结肠癌患者外周血中检测到CTCs,提示其临床病理分期也可能较差。
Objective To understand the relationship between circulating tumor cells (CTCs) and clinical pathologic stages in patients with colon cancer.Methods CTCs counts in peripheral blood of untreated patients with colon cancer were detected by CellSearch technique.The relationship between CTCs and clinical pathologic stages of colon cancer was analyzed.Results CTCs in peripheral blood were detected in 40.6% (13/32) untreated cases of colon cancer.Significant relationships of positive CTCs were identified with colon cancer infiltration, TNM stage, and blood vessel infiltration (P<0.05), but not with age, sex, tumor size, and nerve infiltration.The Ⅲ+Ⅳ TNM stage patients had a much higher positive rate of CTCs than the Ⅰ+Ⅱ TNM stage patients (P<0.05).Conclusion CTCs can be detected in the peripheral blood of colon cancer patients, indicating higher clinicopathological stages.
