Growing evidences for tumor heterogeneity confirm that single-tumor biopsies frequently fail to reveal the widespread mutagenic profile of tumor. Repeated biopsies are in most cases unfeasible, especially in advanced cancers. We describe here how circulating tumor cells (CTCs) isolated from minimally invasive blood sample might inform us about intratumor heterogeneity, tumor evolution and treatment resistance. We also discuss the advances of CTCs research, most notably in molecularly selected non-small cell lung cancer (NSCLC) patients, highlighting challenges and opportunities related to personalized therapy.
越来越多关于肿瘤异质性的证据证实,单次肿瘤活检常常无法揭示肿瘤广泛的诱变特征。在大多数情况下,重复活检并不可行,尤其是在晚期癌症中。我们在此描述了如何从微创血样中分离出的循环肿瘤细胞(CTC)能够让我们了解肿瘤内异质性、肿瘤演变和治疗耐药性。我们还讨论了CTC研究的进展,最显著的是在分子选择的非小细胞肺癌(NSCLC)患者中的进展,强调了与个性化治疗相关的挑战和机遇。
