肿瘤转移在临床上为绝大多数恶性肿瘤的致死性问题。原发肿瘤可进行手术切除或放射治疗,但已播散的癌症却难于用上述手段治疗而不损伤正常组织。因此肿瘤转移对癌症治疗是一种严重的挑战,且由于其致命性,多年来转移已成为癌症基础研究的主要课题。转移性肿瘤细胞是如何发展的?转移性肿 Tumor metastasis is clinically fatal for most malignancies. Primary tumors may undergo surgical resection or radiation therapy, but already disseminated cancers are difficult to treat with the above methods without damaging normal tissues. Therefore, tumor metastasis is a serious challenge for cancer treatment, and due to its fatal nature, metastasis has become the main topic of basic cancer research for many years. How are metastatic tumor cells developed? Metastatic tumors
