Evaluating the Effect of Perioperative Caloric Restriction Program on Perioperative Outcomes in Patients With Obesity and Endometrial Cancer

Evaluating the Effect of Perioperative Caloric Restriction Program on Perioperative Outcomes in Patients With Obesity and Endometrial Cancer

80% of endometrial cancer patients are overweight or obese. Preclinical and clinical data have shown that caloric restriction (CR) protects against organ injury and decreases perioperative morbidity. This is a feasibility trial to evaluate the effect of a 6 week perioperative CR on surgical and patient-reported outcomes in 20 obese newly diagnosed endometrial cancer patients. The intervention will provide individualized CR program, meal replacement products and nutritional counselling sessions.

Inclusion Criteria:

• Newly diagnosed with Endometrial Cancer
• BMI30 kg/m2

• Have ECOG performance status of 0-1
• Have a life expectancy of at least 1 year

Exclusion Criteria:

• Inability to communicate in English
