RecruitingBehavioural interventionTrial of Exercise and Lifestyle for Women With Ovarian and Endometrial CancerAn anticipated 200 women with newly diagnosed ovarian and endometrial cancer scheduled to receive chemotherapy (adjuvant chemotherapy after surgery or neoadjuvant chemotherapy before surgery) will be recruited from Smilow Cancer Hospital Network at Yale Cancer Center (YCC) and Sylvester Comprehensive Cancer Center (SCCC) at University of Miami. Participants will be randomized to an exercise and medical nutrition intervention arm with weekly counseling sessions throughout chemotherapy, or a control arm. Study assessments will be conducted at baseline, post-chemotherapy/end of intervention and at 1-year post diagnosis. Women who are prescribed neoadjuvant therapy will have additional assessments prior to surgery. Data required to calculate the primary endpoint (relative dose intensity of chemotherapy) will be abstracted from the medical record directly following each chemotherapy session.
