摘要:

背景:肿瘤复发的原因是具有自我更新特性的肿瘤干细胞未能彻底清除,于是如何标记并消灭肿瘤干细胞成为治疗肿瘤的关键所在。

目的:观察结直肠癌组织中CD44+/C-myc+细胞的形态分布及数量,并探讨其表达与患者肿瘤复发转移的关系。
方法:选取150例结直肠腺癌患者的病理组织制成组织芯片,采用免疫组化双重染色观察并计数CD44+/ C-myc+细胞,并与正常组织、腺瘤组织比较。使用手机、书信等方式对患者进行随访,统计患者的复发转移与CD44+/C-myc+细胞表达的关系。
结果与结论:CD44+/C-myc+细胞在正常组织中无分布,在腺瘤组织中极少散在分布,在腺癌组织中少量单个点状或灶性分布,双阳细胞数量与腺癌分化程度、浸润深度、淋巴结转移有关(P < 0.05)。单因素分析患者腺癌的总生存率、无进展生存率均与双阳性细胞数量、淋巴结有无转移、Ducks分期有关(P < 0.05),多因素分析患者的总生存率与双阳性细胞数有关,无进展生存率与双阳性细胞数及Ducks分期有关。结果表明结直肠组织中CD44+/C-myc+细胞极有可能为腺癌干细胞;Ducks分期、CD44+/C-myc+细胞的数量是影响患者预后的重要因素。

Abstract:

BACKGROUND: Tumor recurrence results from the incomplete removal of cancer stem cells with self-renewal characteristics, and then how to label and eliminate cancer stem cells becomes the key to cancer treatment.

OBJECTIVE: To observe the morphology,distribution and number of CD44+/C-myc+ cells in colorectal cancer, and to explore the relationship between the expression and postoperative metastasis.
METHODS: Pathological tissues from 150 patients with colorectal cancer were taken to prepare tissue microarray, in order to observe and count CD44+/C-myc+ cells by using immunohistochemical double staining. Patients were followed up through mobile phones , letters , and so on, and the relationship between the expression of CD44+/C-myc+ cells and postoperative metastasis were statistically recorded.
RESULTS AND CONCLUSION: There was no CD44+/C-myc+ cells in normal tissue and little in adenoma. A small number of CD44+/C-myc+ cells distributed as dots or focal lesions in adenocarcinoma. The number of CD44+/C-myc+ cells was related to the degree of adenocarcinoma differentiation, depth of invasion, and lymph node metastasis (P < 0.05). The univariate analysis showed that the overall survival rate and progression-free survival rate were associated with the number of CD44+/C-myc+ cells, lymph node metastasis and Ducks staging in adenocarcinoma (P < 0.05). The multivariate analysis showed that the overall survival rate was related to CD44+/C-myc+ cell amount and the progression-free survival rate was related to CD44+/C-myc+ cell amount and the Ducks staging. Therefore, CD44+/C-myc+ cells are probably cancer stem cells, and Ducks staging and CD44+/C-myc+ cell amount are important prognostic factors for colorectal cancer.
