Targeting glucose metabolism has emerged as a promising strategy for inhibiting tumor growth. However, we herein uncover an unexpected paradox: while glucose deprivation through a low-carbohydrate diet or impaired in situ metabolism suppresses primary tumor growth, it simultaneously promotes lung metastasis by depleting natural killer (NK) cells via lung macrophages. Mechanistically, glucose deprivation induces endoplasmic reticulum (ER) stress, activating HMG-CoA reductase degradation protein 1 (HRD1) to catalyze K63-linked ubiquitination of TRAIL, which is then packaged into exosomes via the endosomal sorting complex required for transport (ESCRT) complex. These exosomal TRAIL molecules polarize PVR+ macrophages, triggering NK cell exhaustion and establishing a pre-metastatic niche. Notably, TIGIT blockade not only prevents metastasis induced by glucose deprivation but also enhances its anti-tumor effects. Clinically, low glucose metabolism correlates with higher 2-year postoperative recurrence across 15 cancer types. Furthermore, plasma exosomal TRAIL outperforms traditional markers, such as α-fetoprotein (AFP) and tumor size, in predicting early postoperative lung metastasis, revealing both the risks and therapeutic potential of targeting glucose metabolism.
