简要总结
Rationale/ gaps in existing knowledge: Intermittent fasting(IF) is a novel dietary intervention that has been demonstrated to improve the efficacy of anticancer therapy. Time-restricted eating (TRE), a specific form of IF that restricts the daily eating window without calorie
restriction, is safe, affordable, acceptable, and sustainable for patients. TRE synchronizes the circadian rhythm as well as exerts its metabolic effects mediated by IGF1 and modulation of autophagy. However, the effects of TRE on human cancer prognosis remain unknown because of a lack of randomized clinical trials (RCT).
Novelty: TRE has not been systematically evaluated in an RCT to see its impact on survival in cancer. Objectives We propose to study the impact of TRE on progression-free survival in patients with ovarian and endometrial cancers through an RCT.
Methods We will include patients with epithelial ovarian and endometrial cancers who have
completed their surgery and adjuvant therapies. Diabetics will be excluded. They will be randomized 1:1 to a 6-month TRE schedule (eating time: 8 am to 8 pm without any calorie restriction, followed by 12 hours of fasting) versus the usual diet. The primary endpoint will
be the 2-year PFS rates. The other objectives will include changes in metabolic health parameters (HbA1c, Lipid profile, hs-CRP, IGF1, and Insulin levels) and stool samples for changes in the gut microbiome.
Expected outcome: We expect to find a significantly better PFS in the TRE arm and significant differences in metabolic parameters as well as the gut microbiome.
