The number of subjects participating in this study is up to 40 advanced cancer patients. The research subject is responsible for the medical expenses incurred in the usual standard medical procedures, and the researcher is responsible for the examination expenses (brain magnetic resonance imaging, blood sampling) performed by participating in other studies.~This study runs until Feb 01, 2024. After enrolling in the study, patients with advanced cancer participate in mindfulness-based behavioral therapy once a week for eight weeks. All research subjects participating in this study will have an interview to collect basic information, fill out a questionnaire for index evaluation, blood collection, and brain magnetic resonance imaging. Participants participating in this study will receive specific evaluations as follows.~Interview to gather basic information: demographic information, (if applicable) psychiatric symptoms and treatment-related information are collected.~Filling out questionnaires for psychological evaluation and behavioral data collection: 4 times [Baseline, 2 weeks later, 4 weeks later, 8 weeks later (Post-treatment)], Psychiatry Fill out a questionnaire to comprehensively evaluate your symptoms and psychological state.~Blood collection: 6ml of blood is collected twice before and after treatment.~Brain Magnetic Resonance Imaging: Make an appointment and visit the examination room in the hospital to perform a total of 2 times before and after treatment.~Clinical symptom and progress data are collected if patients have previously been treated at this hospital, and medical information that occurs after study registration is collected every one month during the study participation period.~Distress Indicators~2022 NCCN Guidelines for Distress Management's Korean version of Distress Thermometer (DT) and Problem List (PL)~Perceived Stress Scale-4 (PSS-4) Indicators of depression and anxiety characteristics~Brief Edinburgh Depression Scale (BEDS)~Beck Depression Inventory-ll (BDI-ll)~Beck Anxiety Inventory (BAI)~Hospital Anxiety and Depression Scale (HADS) Mindfulness Characteristics and Symptom Related Indicators~Toronto Mindfulness Scale (TMS)~Self-Compassion Scale-Short Form (SCS-SF)~Demoralization Scale-II (DS-II-Kr)~Thought-Action Fusion Scale (TAFS) Quality of life and resilience indicators~Functional Assessment Cancer Therapy-General (FACT-G)~WHO Quality of Life-BREF (WHOQOL-BREF)~The Brief Resilience Scale (BRS) Epigenetic data~DNA methylation analysis flow DNA preparation → uracil change of non-methylated cytosine using bisulfate → amplification using PCR → methylation detection by methylation specific PCR~Selection of candidate genes - Experience in prior research on OXTR and FKBP5gene → Application to same gene methylation studies Brain imaging data~Acquisition of magnetic resonance imaging (MRI) - structural imaging (T1), functional imaging (fMRI), diffusion tensor imaging (DTI)
'Distress' refers to emotional distress, including psychological distress, in cancer patients. This study aims to explore whether mindfulness-based cognitive-behavioral therapy for cancer patients is effective in relieving distress and to discover neurophysiological factors that contribute to relieving distress. Mindfulness meditation, which is the core of mindfulness-based cognitive behavioral therapy, can develop cognitive flexibility through 'awareness of what is happening now'. In this study, a mindfulness-based cognitive behavioral therapy program is implemented for patients with advanced cancer, and clinical characteristics and conditions including distress level are observed through questionnaires and interviews. In addition, genetic data and brain imaging data are collected through blood sampling and brain magnetic resonance imaging. The ultimate goal of this study is to prove the therapeutic efficacy of a mindfulness-based cognitive behavioral therapy program for distress of patients with advanced cancer through an in-depth and multifaceted integrated approach, and to understand the related neurophysiological mechanisms.
