Sleep Changes and Biomarkers After Breast Cancer Treatment

The Sleep After Breast Cancer (ABC) Study - Examining Sleep Changes and Biomarkers Among Breast Cancer Patients

Observational Ohio State University Comprehensive Cancer Center · NCT07341503

This project will see how sleep patterns and stress-related biological markers change from treatment through survivorship in people with stage I–III hormone receptor–positive breast cancer.

What this trial studies

This observational study follows people with stage I–III hormone receptor–positive breast cancer from after primary surgery through survivorship to track sleep and related biomarkers. Participants wear a wrist actigraphy device, provide cheek swab, saliva, and hair samples, complete repeated surveys, and allow review of medical records. Researchers will analyze actigraphy-measured sleep duration and self-reported sleep quality over time and link these measures to sociodemographic, treatment, social support, and built environment factors, with attention to race, ethnicity, and underserved communities. The study will also examine associations between sleep and markers of biological aging, stress, and inflammation.

Who should consider this trial

Good fit: Adults (≥18) with stage I–III hormone receptor–positive breast cancer who are post-primary surgery but before chemotherapy or radiation, able to consent, read English, and access their medical records.

Not a fit: People with stage IV/metastatic disease, those unable to consent or complete study tasks, non–English speakers, or patients with other active new malignancies are unlikely to be eligible or to gain direct benefit from the study’s findings.

Why it matters

Potential benefit: If successful, the findings could help identify patients at risk for persistent sleep problems and elevated biological stress so clinicians can target supportive interventions during and after treatment.

How similar studies have performed: Prior observational studies have linked sleep disruption to inflammation and stress markers in cancer survivors, but few have longitudinally tracked actigraphy-measured sleep and biomarkers from treatment through survivorship across diverse communities.
