Fasting InTervention for Endometrial Cancer (FIT-ENDO)

27. května 2026 aktualizováno: Tracy E Crane, PhD, RDN, University of Miami

Fasting InTervention for Endometrial Cancer (FIT-ENDO)

The goal of this study is to find out if it is safe for women with endometrial cancer who are going to have surgery to fast (not eat) overnight. Studies have shown that women with endometrial cancer often have problems with metabolism, like high blood sugar. These problems can cause inflammation and may help cancer grow or make treatment less effective. Early research shows that fasting overnight might help improve these problems.

Percentage Change in Metabolic Biomarker Levels at Post-Surgery Compared to Pre-Surgery, in the Intervention Versus Control Group
Časové okno: Baseline, about 28 Days
Change in metabolic biomarker levels (insulin, glucose, IGF-1, HbA1c) at post-surgery compared to pre-surgery, among participants in both the prolonged overnight fasting (POF) intervention and attention control groups. Blood specimens collected at baseline (T0), the day of surgery (T1) will be used to analyze changes in metabolic biomarker levels.
Baseline, about 28 Days
Fold Change in Concentration of Blood and Serum Metabolomics at Post-Surgery compared to Pre-Surgery in the Intervention Versus Control Group
Časové okno: Baseline, about 28 Days
Fold change in concentration of blood and serum metabolomics (> 450 water-soluble metabolites and 600 lipid-related metabolites) at post-surgery compared to pre-surgery will be reported among participants in both the prolonged overnight fasting (POF) intervention and attention control groups. Blood specimens collected at baseline (T0), the day of surgery (T1) will be analyzed using Mass Spectrometry (MS) or Nuclear Magnetic Resonance (NMR). Fold Change (FC) represents the ratio of the average metabolite concentration at post-surgery compared to pre-surgery.
Baseline, about 28 Days
Change in Quality of Life As Measured By Scores on the PROMIS-29 Questionnaire
Časové okno: Baseline, about 28 Days
Change in participant quality of life in both the intervention and control groups as measured by scores on the Patient-Reported Outcomes Measurement Information System-29 (PROMIS-29) questionnaire will be reported. PROMIS-29 questionnaire is a 29-item validated measure with seven domains of health, including physical function, anxiety, depression, pain interference, fatigue, sleep disturbance, ability to participate in social roles and activities and pain intensity. Scores collected at baseline (T0) will be compared to scores collected the day of surgery (T1). Higher scores represent worse symptoms for symptom-oriented domains (anxiety, depression, fatigue, pain intensity, pain interference, and sleep disturbance) and better health outcomes for function-oriented domains (physical functioning and ability to participate in social roles and activities).
Baseline, about 28 Days
Change in Quality of Life As Measured By Scores on the Rosenburg Self-Esteem Scale
Časové okno: Baseline, about 28 Days
Change in participant quality of life in both the intervention and control groups as measured by the Rosenburg Self-Esteem Scale will be reported. The Rosenberg Self-Esteem Scale (RSES) is a 10-item self-report questionnaire measuring global self-worth and self-acceptance. It uses a 4-point Likert scale (strongly agree to strongly disagree), with scores ranging from 0-30 (or 10-40). Scores below 15 indicate low self-esteem. Scores collected at baseline (T0) will be compared to scores collected the day of surgery (T1).
Baseline, about 28 Days
Change in Quality of Life As Measured By Scores on the Hopwood's Body Image Scale
Časové okno: Baseline, about 28 Days
Change in participant quality of life in both the intervention and control groups as measured by scores on the Hopwood's Body Image Scale will be reported. The Hopwood's Body Image Scale is a 10-item questionnaire used to measure affective, behavioral, and cognitive body image symptoms. Participants can indicate body image symptoms on a 4-point scale (0 "not at all" to 3 "very much"). The total score ranges from 0 to 30 and can be calculated by summing up the 10 items. A higher score means a higher level of body image disturbance. Scores collected at baseline (T0) will be compared to scores collected the day of surgery (T1).
Baseline, about 28 Days
Change in Sleep Quality As Measured By Scores on the Pittsburgh Sleep Quality Index
Časové okno: Baseline, about 28 Days
Change in participant quality of life in both the intervention and control groups as measured by scores on the Pittsburgh Sleep Quality Index (PSQI) questionnaire will be reported. The PSQI is a self-administered questionnaire for evaluating subjective sleep quality. PSQI global scores range from 0 to 21, with higher scores indicating worse sleep quality. Scores collected at baseline (T0) will be compared to scores collected the day of surgery (T1).
