肿瘤细胞与疾病进展有关,会影响治疗敏感度。循环肿瘤细胞(CTC)被认为是远处转移的种子。循环肿瘤细胞的存在使得通过简单的血标本检测肿瘤组织信息成为可能。CLIN CANCER RES近期发表了一篇文章,研究不同循环肿瘤细胞亚型及其他细胞在前列腺癌中发挥的预后作用。

肿瘤细胞与疾病进展有关,会影响治疗敏感度。循环肿瘤细胞(CTC)被认为是远处转移的种子。循环肿瘤细胞的存在使得通过简单的血标本检测肿瘤组织信息成为可能。CLIN CANCER RES近期发表了一篇文章,研究不同循环肿瘤细胞亚型及其他细胞在前列腺癌中发挥的预后作用。

作者分析了81例前列腺癌患者(43例趋势抵抗患者和38例未治疗的局部肿瘤患者)循环肿瘤细胞亚组,并将其与疾病进展特征相联系。利用AUC分析比较单独血浆PSA水平和PSA联合EMTing CTC数对远处转移的预测效力。利用Cox模型分析循环巨核细胞和肿瘤患者生存之间的关系。研究结果表明,大部分VIM+/CD45-细胞是恶性的,在几个遗传区域存在遗传改变。CK-/VIM+/CD45- CTC与肿瘤负荷,肿瘤侵袭性和不良预后有关。在有限的样本量中,与其他CTCs亚型相比,CK+/VIM+/CD45- CTCs与远处转移关系更大。PSA水平联合CK+/VIM+/CD45- CTCs增强肿瘤远处转移的预测效力。循环巨核细胞数与晚期前列腺癌患者较好的预后有关,间充质CTCs与巨核细胞数量之间的差异与不良预后显着相关。

文章最后认为,CTC分析以及巨核细胞与肿瘤预后的关系可以增强对肿瘤远处转移的理解及对肿瘤进展的检测。
