Although the prevalence and impact of cancer-related fatigue has been well established, very little is known about its predictors, mechanisms for development, and persistence post-treatment. A new research study at the Cedars-Sinai Samuel Oschin Comprehensive Cancer Institute, in partnership with UCLA, is aimed at identifying breast cancer patients most susceptible to post-treatment fatigue by measuring biological, behavioral and social risk factors.
"Understanding who is at risk for post-treatment fatigue, and why, is the first critical step in the development of personalized, targeted interventions for the treatment and prevention of breast cancer-related fatigue," said Arash Asher, MD, director of cancer rehabilitation and survivorship at the Cedars-Sinai Samuel Oschin Comprehensive Cancer Institute and the medical center's primary investigator on the study. "It is our hope to identify the biological and behavioral risk factors that contribute to a patient's overall risk for fatigue."
The research study aims to identify biological factors that may cause more severe fatigue in patients post-treatment. Among the biological markers studied, researchers will evaluate the role of inflammation as a key mechanism for cancer-related fatigue. Extensive research has shown a correlation between inflammatory markers in the blood and levels of fatigue among patients during and after breast cancer treatment.
The study also will examine psychological factors, including a history of depression and early-life stressors, that may increase risk for developing post-treatment fatigue in women with early-stage disease.
