A multimodal prehabilitation program for the reduction of post-operative complications after surgery in advanced ovarian cancer under an ERAS pathway: a randomized multicenter trial (SOPHIE)


Background Multimodal prehabilitation programs that combine exercise training, nutritional support, and optimize psychological status have demonstrated efficacy in reducing post-operative complications in non-gynecological abdominal surgeries; however, the benefit in advanced ovarian cancer is unclear.

Primary Objective To compare the post-operative complications of a multimodal prehabilitation program in patients undergoing cytoreductive surgery for advanced ovarian cancer with standard pre-operative care.

Study Hypothesis Multimodal prehabilitation reduces post-operative complications in patients undergoing cytoreductive surgery for advanced ovarian cancer and subsequently reduces the length of hospital stay and time to initiation of adjuvant therapy.

Trial Design This prospective, multi-institutional, randomized clinical trial will randomize candidates for surgery to either the standard of care or multimodal prehabilitation consisting of (1) 2- or 3-weekly supervised high-intensity resistance training sessions and promotion of physical activity through a mobile phone application; (2) respiratory physiotherapy; (3) nutrition counseling with supplementation as needed; and (4) weekly psychological and cognitive behavioral sessions. Baseline, pre-operative and 1 month post-operative data will be collected. An independent blinded evaluator will collect intra- and post-operative surgical data.

Major Inclusion/Exclusion Criteria Women with advanced ovarian cancer International Federation of Gynecology and Obstetrics (2014) stage III or IV scheduled to undergo primary debulking surgery, interval debulking surgery,or secondary or tertiary cytoreductive surgery will be included. Women are eligible if they are able to undergo a minimum of 2 weeks of prehabilitation prior to surgery. Patients with <75% adherence to the total program will be excluded.

Primary Endpoint Post-operative complications in patients with advanced ovarian cancer undergoing cytoreductive surgery according to the Comprehensive Complication Index.

Sample Size 146 patients will be included, 73 in each group.

Estimated Dates for Completing Accrual and Presenting Results Accrual should be completed in December 2024 with results reported soon thereafter.

Trial Registration Number NCT04862325.
