Abstract

Cancer cells that leave the primary tumor can seed metastases in distant organs, and it is thought that this is a unidirectional process. Here we show that circulating tumor cells (CTCs) can also colonize their tumors of origin, in a process that we call "tumor self-seeding." Self-seeding of breast cancer, colon cancer, and melanoma tumors in mice is preferentially mediated by aggressive CTCs, including those with bone, lung, or brain-metastatic tropism. We find that the tumor-derived cytokines IL-6 and IL-8 act as CTC attractants whereas MMP1/collagenase-1 and the actin cytoskeleton component fascin-1 are mediators of CTC infiltration into mammary tumors. We show that self-seeding can accelerate tumor growth, angiogenesis, and stromal recruitment through seed-derived factors including the chemokine CXCL1. Tumor self-seeding could explain the relationships between anaplasia, tumor size, vascularity and prognosis, and local recurrence seeded by disseminated cells following ostensibly complete tumor excision.

摘要

癌细胞离开原发性肿瘤后可以在远处器官播种转移灶,人们认为这是一个单向的过程。在这里,我们表明循环肿瘤细胞(CTC)也可以定植其起源肿瘤,这个过程我们称之为“肿瘤自播种”。在小鼠中,乳腺癌、结肠癌和黑色素瘤肿瘤的自播种主要由侵袭性 CTC 介导,包括具有骨、肺或脑转移倾向的 CTC。我们发现,肿瘤来源的细胞因子 IL-6 和 IL-8 作为 CTC 的趋化因子,而 MMP1/胶原酶-1 和肌动蛋白细胞骨架成分 fascin-1 是 CTC 浸润到乳腺肿瘤的介质。我们表明,自播种可以通过种子来源的因子加速肿瘤生长、血管生成和基质募集,包括趋化因子 CXCL1。肿瘤自播种可以解释间变、肿瘤大小、血管生成和预后之间的关系,以及在看似完全切除肿瘤后,播散细胞引发的局部复发。
