PET/MRI, psychobehavioral tests and questionnaires, serum biomarkers and stool sample
PET/MRI, psychobehavioral tests and questionnaires, serum biomarkers and stool sample: Neuroimaging data were collected by integrated PET/MRI machine, and collected the psychobehavioral data, the serum and stool samples of participants.
Study summary
To explore the cognitive impairment caused by chemotherapy and endocrine therapy in premenopausal breast cancer patients and to find biomarkers with early predictive effect on this cognitive impairment by using multimodal integrated PET/MRI technology combined with psychobehavioral technology.

Primary outcome measure(s)
Change of gray matter volume of whole brain — Baseline, 6,18,30 months later Gray matter volume will be measured with magnetic resonance imaging (high resolution T1-weighted image)
Change of white matter integrity of whole brain. — Baseline, 6,18,30 months later Fractional anisotropy, axial diffusivity and radial diffusivity will be measured with magnetic resonance imaging (diffusion tensor imaging)
Change of metabolism of glucose in the brain — Baseline, 6,18,30 months later Accumulation of 18F-fluorodeoxyglucose(18F-FDG) will be analyzed by time-related Positron emission tomography
Change of functional connectivity of whole brain — Baseline, 6,18,30 months later Functional connectivity will be measured with magnetic resonance imaging based on blood oxygen level dependence
Change of verbal learning and memory — Baseline, 6,18,30 months later Verbal learning and memory scores will be assessed with Hopkins Verbal Learning Test-Revised.The minimum value is 0, and the maximum value is 12. The higher scores mean a better outcome.
Change of information processing speed — Baseline, 6,18,30 months later Information processing speed scores will be assessed with Wechsler Adult Intelligence Scale(WAIS-III) Digit Symbol Coding score.The minimum value is 0, and the maximum value is 90. The higher scores mean a better outcome.
Change of executive function — Baseline, 6,18,30 months later Executive function scores will be assessed with Stroop color-word test.The minimum value is 0, and the maximum value is 50. The higher scores mean a better outcome.
Change of attention, verbal short term and working memory — Baseline, 6,18,30 months later Attention, verbal short term and working memory scores will be assessed with Digit span.The minimum value is 0, and the maximum value is 12. The higher scores mean a better outcome.
Change of life quality. — Baseline, 6,18,30 months later Quality of life scores will be assessed with Quality-of-Life Questionnaire C30. The minimum value is 30, and the maximum value is 126. The higher scores mean a worse outcome.
Change of anxiety — Baseline, 6,18,30 months later Anxiety scores will be assessed with Self-Rating Anxiety Scale.The minimum value is 20, and the maximum value is 80. The higher scores mean a worse outcome.
Change of depression — Baseline, 6,18,30 months later Depression scores will be assessed with Self-rating depression scale.The minimum value is 20, and the maximum value is 80. The higher scores mean a worse outcome.
Change of fatigue — Baseline, 6,18,30 months later Fatigue scores will be assessed with Fatigue Severity Scale. The minimum value is 9, and the maximum value is 63. The higher scores mean a worse outcome.
Change of sleep — Baseline, 6,18,30 months later Sleep scores will be assessed with Pittsburgh sleep quality index.The minimum value is 9, and the maximum value is 36. The higher scores mean a worse outcome.
