Study on the Traditional Chinese Medicine Syndrome Characteristics of Cancer-related Fatigue and Their Correlation with Thyroid Function Level

Background The integration of Traditional Chinese Medicine (TCM) and Western Medicine in a multidisciplinary approach is the future direction for the diagnosis and treatment of Cancer-Related Fatigue (CRF). However, the lack of standard criteria for syndrome differentiation and treatment selection limits the application of TCM in Western and international contexts. Patients with CRF often experience fatigue associated with metabolic and energy balance abnormalities, with thyroid function playing a critical role in the body's energy metabolism and regulation. Objective To analyze the TCM syndrome characteristics of CRF and explore their correlation with thyroid function levels, providing a reference for the integrated diagnosis and treatment of CRF and mechanism research in both TCM and western medicine. Methods The study included cancer patients who visited the oncology outpatient and inpatient departments of the China Academy of Chinese Medical Sciences Xiyuan Hospital in 2021.
