Abstract
Purpose: This study examined the relationships between a single-nucleotide polymorphism (SNP) of brain-derived neurotrophic factor (BDNF) rs6265 and psychoneurological (PN) symptoms in female cancer survivors.
Methods: This secondary analysis examined 393 study participants. In addition to demographic variables, self-reported PN symptom scores (anxiety, bodily pain, depression, fatigue, neuropathic pain, and sleep disturbance) were collected using the Patient-Reported Outcomes Measurement Information System and 36-Item Short-Form Health Survey. Buccal swab samples were collected to obtain genotypes for BDNF rs6265 (Val/Val, Val/Met, or Met/Met). The PN symptom scores were compared across genotypes, and the relationships were examined using a regression model. We also explored correlations between different symptoms within each genotype.
Results: Participants with the Met/Met genotype reported significantly worse cancer-related fatigue and neuropathic pain, which was confirmed by rank-based regression analysis. In addition, cancer-related fatigue was correlated with other PN symptoms, particularly depression. These correlations were stronger in study participants with the Met/Met genotype than those with other genotypes.
Conclusion: Our study suggests that female cancer survivors with the Met/Met genotype of BDNF rs6265 are likely to experience worse cancer-related fatigue and neuropathic pain and that cancer-related fatigue is a good predictor of co-occurring PN symptoms in this population.
Implications for cancer survivors: Our findings advance the scientific community's understanding of cancer-related PN symptoms experienced by female cancer survivors, especially the unique role of BDNF rs6265 polymorphism in these symptoms. Our findings offer valuable insights for clinical practice that the symptom experience among female cancer survivors may vary based on BDNF genotypes.
期刊介绍：
Cancer survivorship is a worldwide concern. The aim of this multidisciplinary journal is to provide a global forum for new knowledge related to cancer survivorship. The journal publishes peer-reviewed papers relevant to improving the understanding, prevention, and management of the multiple areas related to cancer survivorship that can affect quality of care, access to care, longevity, and quality of life. It is a forum for research on humans (both laboratory and clinical), clinical studies, systematic and meta-analytic literature reviews, policy studies, and in rare situations case studies as long as they provide a new observation that should be followed up on to improve outcomes related to cancer survivors. Published articles represent a broad range of fields including oncology, primary care, physical medicine and rehabilitation, many other medical and nursing specialties, nursing, health services research, physical and occupational therapy, public health, behavioral medicine, psychology, social work, evidence-based policy, health economics, biobehavioral mechanisms, and qualitative analyses. The journal focuses exclusively on adult cancer survivors, young adult cancer survivors, and childhood cancer survivors who are young adults. Submissions must target those diagnosed with and treated for cancer.
