Oncofertility‐related psycho‐educational therapy for young adult patients with breast cancer and their partners: Randomized controlled trial

A couples' psycho-educational program called Oncofertility! Psycho-Education and Couple Enrichment (O!PEACE) therapy was created and its effect when provided before cancer treatment was examined.This multicenter randomized controlled trial with nonmasking, parallel two-group comparison enrolled women aged 20 to 39 years with early-stage breast cancer and their partners. They were randomly assigned to receive O!PEACE (37 couples) or usual care (37 couples). Primary end points were cancer-related posttraumatic stress symptoms, symptoms of depression, and anxiety. Secondary end points were stress-coping strategies, resilience, and marital relationship.Women receiving psycho-educational therapy had significantly reduced Impact of Event Scale-revised version for Japanese scores (p = .011, ηp2 = = .089). For patients with Impact of Event Scale-revised version for Japanese scores at baseline ≥18.27, O!PEACE therapy improved these scores when compared with usual care (U = 172.80, p = .027, r = 0.258). A >5-point reduction was present in 59.3% and 30% of women in the O!PEACE therapy and usual-care groups, respectively. For partners, O!PEACE therapy significantly improved stress-coping strategies (95% CI, -0.60 to -0.05; p = .018, ηp2 = = .074) and escape-avoidance marital communication (95% CI, -0.33 to -0.08; p = .001, ηp2 = .136). O!PEACE therapy significantly improved the partners' support (95% CI, 0.10-0.50; p = .001, ηp2 = .127), the rate of receiving fertility preservation consultations, and knowledge levels.O!PEACE therapy before cancer treatment can improve posttraumatic stress symptoms, stress-coping behavior, and marital relationships. Larger sample sizes and longer term follow-up are required.A psycho-educational program, the Oncofertility! Psycho-Education and Couple Enrichment (O!PEACE) therapy program was developed and evaluated for women diagnosed with breast cancer and their partners. A multicenter randomized controlled trial showed that the O!PEACE psycho-educational therapy, with only two precancer treatment sessions, can reduce cancer-related posttraumatic stress symptoms and improve oncofertility knowledge and marital relationships in young adult patients with breast cancer. The therapy could also improve stress-coping strategies in marital communications with their partners. Couples may use O!PEACE psycho-educational therapy to consider fertility preservation and improve their psychosocial aspects.
