In tumor-bearing mice, cyclic fasting or fasting-mimicking diets (FMD) enhance the activity of antineoplastic treatments by modulating systemic metabolism and boosting antitumor immunity. Here we conducted a clinical trial to investigate the safety and biological effects of cyclic, five-day FMD in combination with standard antitumor therapies. In 101 patients, the FMD was safe, feasible, and resulted in a consistent decrease of blood glucose and growth factor concentration, thus recapitulating metabolic changes that mediate fasting/FMD anticancer effects in preclinical experiments. Integrated transcriptomic and deep-phenotyping analyses revealed that FMD profoundly reshapes anticancer immunity by inducing the contraction of peripheral blood immunosuppressive myeloid and regulatory T-cell compartments, paralleled by enhanced intratumor Th1/cytotoxic responses and an enrichment of IFNγ and other immune signatures associated with better clinical outcomes in patients with cancer. Our findings lay the foundations for phase II/III clinical trials aimed at investigating FMD antitumor efficacy in combination with standard antineoplastic treatments. Significance: Cyclic FMD is well tolerated and causes remarkable systemic metabolic changes in patients with different tumor types and treated with concomitant antitumor therapies. In addition, the FMD reshapes systemic and intratumor immunity, finally activating several antitumor immune programs. Phase II/III clinical trials are needed to investigate FMD antitumor activity/efficacy. This article is highlighted in the In This Issue feature, [p. 1][1] [1]: /lookup/volpage/12/1?iss=1

禁食模拟饮食是安全的,可重塑癌症患者的新陈代谢和抗肿瘤免疫力

在荷瘤小鼠中,周期性禁食或模拟禁食饮食 (FMD) 通过调节全身代谢和增强抗肿瘤免疫力来增强抗肿瘤治疗的活性。在这里,我们进行了一项临床试验,以研究周期性、为期五天的 FMD 与标准抗肿瘤疗法相结合的安全性和生物学效应。在 101 名患者中,FMD 是安全、可行的,并导致血糖和生长因子浓度持续下降,从而重现了在临床前实验中介导禁食/FMD 抗癌作用的代谢变化。整合的转录组学和深度表型分析表明,FMD 通过诱导外周血免疫抑制性骨髓和调节性 T 细胞区室的收缩,深刻地重塑了抗癌免疫,同时增强肿瘤内 Th1/细胞毒性反应,以及 IFNγ 和其他免疫特征的富集,这些特征与癌症患者更好的临床结果相关。我们的研究结果为 II/III 期临床试验奠定了基础,该试验旨在研究 FMD 与标准抗肿瘤治疗相结合的抗肿瘤疗效。意义:周期性 FMD 具有良好的耐受性,并在患有不同肿瘤类型并接受伴随抗肿瘤治疗的患者中引起显着的全身代谢变化。此外,FMD 重塑全身免疫和肿瘤内免疫,最终激活多种抗肿瘤免疫程序。需要进行 II/III 期临床试验来研究 FMD 抗肿瘤活性/功效。这篇文章在本期专题中突出显示,[p。1][1] [1]: /lookup/volpage/12/1?iss=1 我们的研究结果为 II/III 期临床试验奠定了基础,该试验旨在研究 FMD 与标准抗肿瘤治疗相结合的抗肿瘤疗效。意义:周期性 FMD 具有良好的耐受性,并在患有不同肿瘤类型并接受伴随抗肿瘤治疗的患者中引起显着的全身代谢变化。此外,FMD 重塑全身免疫和肿瘤内免疫,最终激活多种抗肿瘤免疫程序。需要进行 II/III 期临床试验来研究 FMD 抗肿瘤活性/功效。这篇文章在本期专题中突出显示,[p。1][1] [1]: /lookup/volpage/12/1?iss=1 我们的研究结果为 II/III 期临床试验奠定了基础,该试验旨在研究 FMD 与标准抗肿瘤治疗相结合的抗肿瘤疗效。意义:周期性 FMD 具有良好的耐受性,并在患有不同肿瘤类型并接受伴随抗肿瘤治疗的患者中引起显着的全身代谢变化。此外,FMD 重塑全身免疫和肿瘤内免疫,最终激活多种抗肿瘤免疫程序。需要进行 II/III 期临床试验来研究 FMD 抗肿瘤活性/功效。这篇文章在本期专题中突出显示,[p。1][1] [1]: /lookup/volpage/12/1?iss=1 周期性 FMD 具有良好的耐受性,并在患有不同肿瘤类型并接受伴随抗肿瘤治疗的患者中引起显着的全身代谢变化。此外,FMD 重塑全身免疫和肿瘤内免疫,最终激活多种抗肿瘤免疫程序。需要进行 II/III 期临床试验来研究 FMD 抗肿瘤活性/功效。这篇文章在本期专题中突出显示,[p。1][1] [1]: /lookup/volpage/12/1?iss=1 周期性 FMD 具有良好的耐受性,并在患有不同肿瘤类型并接受伴随抗肿瘤治疗的患者中引起显着的全身代谢变化。此外,FMD 重塑全身免疫和肿瘤内免疫,最终激活多种抗肿瘤免疫程序。需要进行 II/III 期临床试验来研究 FMD 抗肿瘤活性/功效。这篇文章在本期专题中突出显示,[p。1][1] [1]: /lookup/volpage/12/1?iss=1 这篇文章在本期专题中突出显示,[p。1][1] [1]: /lookup/volpage/12/1?iss=1 这篇文章在本期专题中突出显示,[p。1][1] [1]: /lookup/volpage/12/1?iss=1
