Managing Cancer and Living Meaningfully (CALM) Intervention on Chemotherapy-Related Cognitive Impairment in Breast Cancer Survivors

Objective: To evaluate the effectiveness and feasibility of Managing Cancer and Living Meaningfully (CALM), which is used to reduce chemotherapy-related cognitive impairment (CRCI), relieve psychological distress, and improve quality of life (QOL) in Chinese breast cancer survivors (BCs). Methods: Seventy-four BCs were enrolled in this study. All patients were randomly assigned to either the CALM group or the care as usual (CAU) group. All patients were evaluated by the Functional Assessment of Cancer Therapy–Cognitive Function (FACT-Cog), Distress Thermometer (DT), and the Functional Assessment of Cancer Therapy–Breast (FACT-B) before and after CALM or CAU application to BCs with CRCI. We compared the differences in all these scores between the CALM group and the control group and analyzed the correlation between cognitive function and QOL. Results: Compared with the CAU group, the performance of the CALM group on the FACT-Cog, DT, and FACT-B showed significant differences before and after CALM ( t = −18.909, −5.180, −32.421, P = .000, .000, .000, respectively). Finally, there was a positive correlation between cognitive function and QOL in breast cancer patients before ( r = 0.579, P = .000) and after ( r = 0.797, P = .000) treatment. Conclusions: The present results indicated that CALM has salutary effects on the improvement of cognitive impairment and QOL and relieves psychological distress in breast cancer patients, which may be due to a positive correlation between psychological distress and cognitive function or QOL.
