肿瘤相关成纤维细胞（cancer-associated fibroblasts，CAFs）是组成肿瘤微环境最主要的基质细胞之一，在肿瘤的生长、转移、耐药和调节肿瘤免疫中起着重要的作用。肿瘤细胞利用自噬来降解代谢过程中的产物，并重新加以利用，以应对环境的变化。自噬将细胞内稳态与影响免疫和新陈代谢的细胞外环境联系起来，其对于癌症的发生、发展和对治疗的反应是至关重要的。本文通过介绍CAFs中自噬的作用和CAFs自噬的调控机制，对CAFs自噬与肿瘤代谢、进展、转移、以及治疗抵抗的研究进展加以阐述。

Cancer-associated fibroblasts (CAFs) are one of the predominant stromal cells that constitute the tumor microenvironment,and play an essential role in tumor growth, metastasis, chemoresistance and tumor immunity. Autophagy is a cellular process through which cells degrade products in the metabolic process and reuse them to respond to environmental stress. Autophagy is important for tumor initiation, progression and response to therapy, as it connects cellular homeostasis with the extracellular environment that affects immunity and metabolism. This review, by introducing the role of autophagy in CAFs and its regulatory mechanism, summarizes the research progress on studies of autophagy in CAFs and tumor metabolism, progression, metastasis and resistance to therapy.
