Photobiomodulation for thinking and memory problems after breast cancer chemotherapy

Breast Cancer and Chemobrain : Effects of Photobiomodulation on the Improvement of Perceived Cognitive Impairment - REGAIN

Not applicable Interventional Centre Hospitalier de Valenciennes · NCT06995443

This trial will try photobiomodulation (a non-drug light therapy) to see if it helps thinking and memory problems in women who finished chemotherapy for breast cancer.

What this trial studies

Adult women who developed perceived cognitive problems during or shortly after intravenous chemotherapy for breast cancer will receive photobiomodulation sessions. Eligibility is determined using FACT-Cog score thresholds and other clinical criteria, and participants must have completed chemotherapy within the past 12 months. The intervention is a non-invasive light therapy delivered in clinic with standardized baseline and follow-up assessments of self-reported cognitive function. Outcomes focus on changes in perceived cognitive impairment and the feasibility of delivering this non‑medicinal treatment.

Who should consider this trial

Good fit: Women aged 18 or older who completed intravenous chemotherapy within the last 12 months, report new or worsening cognitive complaints confirmed by FACT-Cog scores, speak French, and can attend photobiomodulation sessions are ideal candidates.

Not a fit: Patients with cognitive disorders present before chemotherapy, those with psychiatric or behavioral conditions that prevent photobiomodulation, or those without measurable chemo-related complaints are unlikely to benefit.

Why it matters

Potential benefit: If successful, the treatment could reduce chemo-related thinking and memory complaints and improve daily functioning for breast cancer survivors.

How similar studies have performed: Photobiomodulation has been examined in small or pilot studies for cognitive symptoms but evidence is limited and larger trials are needed to confirm benefit.
