简要总结
Extensive preclinical evidence suggests that short-term fasting and fasting mimicking diets (FMDs) can protect healthy cells and render cancer cells more vulnerable to chemotherapy and other therapies. However, fasting is difficult for the old and frail subjects.Therefore, FMDs may be more suitable for postoperative dietary intervention in cancer patients. Colorectal tumors have high glucose consumption, which makes tumor cells very sensitive to changes in nutritional metabolism of the surrounding environment (such as diet restriction / fasting). Previous studies have shown that cyclic FMDs are safe and feasible for cancer patients receiving chemotherapy alone. However, the effects of the FMD in patients under radical surgery for colorectal cancer have not been evaluated so far. This study aims to evaluate the impact of FMDs on postoperative recovery and outcomes of patients with colorectal cancer.

研究组 & 干预措施
Fasting mimicking diet
The cyclic FMD diet consists of a 5 day regimen: day 1 diet of the diet supplies ~1000 kcal (10% protein, 56% fat, 34% carbohydrate), day 2-5 are identical in formulation and provide 800 kcal (9% protein, 44% fat, 47% carbohydrate). At least 4 cyclic FMDs will be performed after operation.

结局指标
主要结局
Disease-free Survival
时间窗: 3 years
DFS is defined as the time from randomisation to the first occurrence of locoregional recurrence, distant metastasis, or death from any cause, whichever occurs first. The data of participants without an event will be censored at the date of the last follow-up. Follow-up of survival will be conducted at least every 3 months beginning at 6 months after surgery. Postoperative recurrence or metastasis will be determined on the basis of imaging studies, endoscopic examination, or histopathological assessment of biopsy specimens, with a review also performed by an expert panel.
