A multimodal intervention program to improve sexual health and self-perceived quality of life in patients treated for cervical cancer: a randomized prospective study (PROVIDENCE trial).

Abstract

Background: Patients with cervical cancer treatment experience an impairment of sexual function and quality of life. This issue is usually underreported and undertreated, and evidence-based interventions are lacking. Prevention of sexual dysfunction is a crucial pillar in improving the quality of life of these patients. The primary objective of this trial is to evaluate the impact of a multimodal intervention, encompassing prevention of vaginal dysfunction and patient education, on sexual function and quality of life in cervical cancer survivors utilizing patient-reported outcome measurements. Methods: Multi-institutional, randomized clinical trial where patients will be randomized 1:2 at diagnosis of initial or locally advanced cervical cancer to control arm or intervention arm. After treatment, control arm patients will undergo standard follow-up by their referring physician. The multimodal intervention for patients in the intervention group includes application of vaginal estrogens plus hyaluronic-acid cream along with use of vaginal vibrator, systematic evaluation of the need of systemic hormone replacement therapy and treatment if needed, and access to online content about sexuality, nutrition, sports and lifestyle habits. Through 4 appointments (at diagnosis, 1, 6, and 12 months after treatment), sexual health, vaginal trophism and self-perceived quality of life of patients in both arms will be assessed with validated questionnaires as female sexual function index (FSFI), European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire 30, and Cx-24, Cervantes Scale, vaginal health index and vaginal thickness assessed by ultrasound. The major inclusion criteria will be patients aged ≥18 years with the International Federation of Gynecology and Obstetrics stage I-III cervical cancer treated with surgery and/or radiotherapy. The primary endpoint will be FSFI score 12 months after treatment, which will be compared between groups. Uni- and multivariate analysis will be performed to identify factors influencing sexual function recovery after treatment. The sample size will be of 120 eligible patients, who will be randomized to detect an improvement of 5.2 points in FSFI score. Complete accrual is estimated in March 2026. To date, the present study has no external funding.
