Moving on After Breast Cancer Trial for Depressed Breast Cancer Survivors in Pakistan

Problem statement: Breast cancer is the most prevalent cancer among women globally. The comorbidity of mental health conditions, such as depression and anxiety, significantly increases mortality rates in this population. Despite the complex rehabilitation needs of breast cancer survivors, there is limited knowledge on how to provide individualised support effectively. Aims/Objectives: The overarching aim of this trial is to evaluate the clinical and cost-effectiveness of a three-stage adaptive intervention for co-morbid depression among breast cancer survivors in Pakistan. Methods: This study will use a Sequential, Multiple Assignment, Randomised Trial (SMART) design to recruit 26,372 breast cancer survivors who have completed initial treatment (surgery and/or radiotherapy or chemotherapy). Participants, aged 18 years and older, will be recruited from primary care units, medical outpatient units, oncology clinics in public hospitals, and charitable organisations across Pakistan. Eligible participants will be screened for Major Depressive Episode (MDE) using the Patient Health Questionnaire (PHQ-9), with a score of 10 or above indicating potential depression. Diagnosis will be confirmed through the Structured Clinical Interview Schedule (SCID). Participants randomised to the intervention arm will receive a three-stage adaptive intervention, progressing through the following levels based on response: First adaptive intervention - Low-intensity guided self-help. Second adaptive intervention - High intensity "Moving On After Breast Cancer Plus" (Moving on ABC Plus), incorporating Cognitive Behavioural Therapy (CBT). Third adaptive intervention - Moving on ABC Plus combined with pharmacological intervention. All participants, regardless of randomisation, will be assessed at baseline, 6-, 18-, 30-, and 48-weeks post-randomisation using standardised questionnaires to measure: Primary outcome: Depression. Secondary outcomes: Anxiety, self-esteem, intrusive thoughts, health-related quality of life, satisfaction with services, and resource utilisation. Additionally, in-depth interviews and focus group discussions (FGDs) will be conducted with multiple stakeholders-including healthcare providers, policymakers, patients, and caregivers-to explore barriers and facilitators of intervention implementation.
