Abstract

Adolescent and young adult cancer patients (AYACPs) experience a high incidence of psychological distress. However, the effect of psychological distress on the functional connectivity between the hemispheres in AYACPs remains unknown. Voxel-mirrored homotopy connectivity detection is an effective way to explore the effects of psychological distress on functional connectivity throughout the brain in AYACPs. Twenty-four AYACPs underwent structural magnetic resonance imaging. Voxel-mirrored homotopy connectivity in the psychological distress group was significantly lower in the superior parietal gyrus, middle frontal gyrus (orbital part), superior frontal gyrus (dorsolateral), superior occipital gyrus, precuneus, lingual gyrus, calcarine fissure and surrounding cortex than in the non-psychological distress group, while in the inferior temporal gyrus and middle frontal gyrus (orbital part), voxel-mirrored homotopy connectivity was significantly higher (p < 0.05). ROC curve analysis showed that the decrease in voxel-mirrored homotopy connectivity in the following brain regions was helpful in distinguishing the psychological distress group from the non-psychological distress group: left superior frontal gyrus (dorsolateral), left calcarine fissure and surrounding cortex, right postcentral gyrus, and left precuneus. Activity imbalances in multiple brain regions exist in AYACPs with psychological distress. Voxel-mirrored homotopy connectivity detection is an effective way to explore the potential neural mechanisms of mental disorders in AYACPs and optimize the treatment of mental disorders.

Highlights

  • Patients diagnosed with cancer between 15–39 years old are defined as adolescent and young adult cancer patients (AYACPs) [1]

  • Negative correlations were found between decreased voxelmirrored homotopy connectivity (VMHC) in some brain areas and Hospital anxiety and depression scale (HADS)-D scores: bilateral superior parietal gyrus and left superior frontal gyrus (r = –0.563, p = 0.029) (Table 4)

  • There were no significant correlations between VMHC values in abnormal brain regions and HADS total scores or HADS-A scores (p > 0.05)

Summary

Introduction

Patients diagnosed with cancer between 15–39 years old are defined as adolescent and young adult cancer patients (AYACPs) [1]. Adolescence and young adulthood are important transitional phases of life with many essential developmental changes. During this time, being diagnosed with cancer may cause unique developmental challenges at this vulnerable point for them [6]. The prevalence and severity of psychological distress (PD) are higher and more common among AYACPs [7, 8]. Objective and accurate early identification of psychological distress in AYACPs is beneficial to cancer treatment.
