Abstract:
Objective To explore changes of topological properties and functional connectivity(FC)of global brain network in breast cancer(BC)patients accompanied by emotional disorders.Methods Forty-three female BC patients(BC group)and 43 age-and education-matched healthy controls(HC group)were prospectively enrolled.The scores of fear of cancer recurrence-total(FCR-total),fear of cancer recurrence inventory(FCRI),general anxiety disorder-7(GAD-7)and patient health questionnaire-9(PHQ-9)for 43 patients in BC group,as well as of anxiety sensitivity index-3(ASI-3),meta-cognitions about health questionnaire(MCQ-HA)and EuroQoL 5-dimension 5-level questionnaire(EQ-5D-5L)for 40 patients in BC group were obtained to evaluate emotional disorders.Meanwhile,the scores of GAD-7 and PHQ-9 were obtained in HC group to exclude for anxiety and depression.Using resting-state functional MRI(rs-fMRI),topological attributes and FC of global brain network were analyzed,and the topological attribute indicators of global brain network were compared between groups.Based on voxel-wise analysis,the regions in global brain related to FC strength(FCS)correlated with each clinical scale score in BC group were analyzed,and spatial similarity analysis of FCS was performed.The correlations of FCS at brain region level and clinical scale scores in BC group were observed.Results All patients in BC group were accompanied by emotional disorders.The clustering coefficient in BC group was lower than that in HC group(t=-2.261,P=0.027).Brain regions related to FCS values correlated with each clinical scale score in BC group were widely distributed in sensorimotor network and higher-order brain network,etc.,and their FCS values were correlated.FCS of ventrolateral nucleus of right thalamus and caudate nucleus were positively correlated with FCR-total(r=0.459,P=0.004)and FCRI(r=0.488,P=0.005).Conclusion BC patients with emotions disorders had dysfunction of brain functional segregation,as well as enhanced FCS in brain regions such as ventrolateral nucleus of right thalamus and caudate nucleus.
