Cognitive impairment in patients with melanoma before adjuvant immune checkpoint inhibitor therapy and associations with brain gray matter, catechol-O-methyltransferase genotype, and psychological factors.

Background: Cancer-related cognitive impairment (CRCI) is a significant concern in patients with cancer but understanding its prevalence and risk factors in patients with malignant melanoma (MMPs) remains limited. This study explores CRCI via a multifaceted approach integrating neurobiological, genetic, and psychological assessments.

Methods: Cognitive functioning across multiple domains was assessed via neuropsychological tests in 47 MMPs before adjuvant immune checkpoint inhibitor therapy, compared with 53 matched healthy controls (HCs).

Biological and psychological predictors of cognitive function in breast cancer patients before surgery.

Purpose: Research suggests that cancer-related cognitive impairment (CRCI) can occur before breast cancer (BC) treatment. The limited extant evidence suggests the underlying mechanisms could be stress-related. Potential psychological and biological predictors of CRCI prior to any BC treatment were examined.

Sleep is important for brain health, having both a restorative function and playing an important role in cognitive functions, e.g., attention, memory, learning, and planning.

Psychological and behavioral symptoms in patients with melanoma: A systematic review and meta-analysis.

Objective: Improved survival rates have made it increasingly important for clinicians to focus on cancer survivorship issues affecting the quality of life of melanoma patients. To provide a comprehensive overview of the disease and treatment-related issues affecting such patients, we conducted a systematic review and meta-analysis of the literature to estimate the prevalence of symptoms of depression, anxiety, fatigue, sleep disturbance, and cognitive problems among melanoma patients, both uveal and cutaneous, before, during and after treatment.

Methods: The review was preregistered with PROSPERO (#CRD42020189847) and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Neurocognitive function and health-related quality of life in a nationwide cohort of long-term childhood brain tumor survivors.

Background: Childhood brain tumor survivors are at high risk of late effects, especially neurocognitive impairment. Limited data are available examining neurocognitive function and associations with quality of life (QoL) in childhood brain tumor survivors. Our aim was to examine neurocognitive function in childhood brain tumor survivors, and associations with QoL and symptom burden.

Circadian disruption and cancer- and treatment-related symptoms.

Cancer patients experience a number of co-occurring side- and late-effects due to cancer and its treatment including fatigue, sleep difficulties, depressive symptoms, and cognitive impairment. These symptoms can impair quality of life and may persist long after treatment completion. Furthermore, they may exacerbate each other's intensity and development over time.

Cancer-related cognitive impairment in non-CNS cancer patients: Targeted review and future action plans in Europe.

Cancer-related cognitive impairment (CRCI) has increasingly been identified over the last two decades in non-CNS system cancer patients. Across Europe, researchers have contributed to this effort by developing preclinical models, exploring underlying mechanisms and assessing cognitive and quality of life changes. The ultimate goal is to develop interventions to treat patients experiencing CRCI.

Examining the Efficacy of Bright Light Therapy on Cognitive Function in Hematopoietic Stem Cell Transplant Survivors.

Patients who have undergone hematopoietic stem cell transplant (HSCT) may experience cognitive impairment that can persist after treatment. Several studies have shown that bright light therapy may improve cognition, potentially due to its effects on the circadian system via brain regions that respond preferentially to light. In this double-blind randomized controlled trial, the efficacy of bright light therapy on cognition was examined in HSCT survivors.

Sleep and allostatic load: A systematic review and meta-analysis.

The detrimental effects of sleep disturbances on health and wellbeing are well-established but not fully understood. The allostatic load model has been suggested as a framework for understanding the adverse effects of sleep disturbances. We conducted a systematic review and meta-analysis to examine the associations of sleep disturbance and sleep duration with allostatic load.

Sleep During Oncological Treatment - A Systematic Review and Meta-Analysis of Associations With Treatment Response, Time to Progression and Survival.

Introduction: Disrupted sleep and sleep-wake activity are frequently observed in cancer patients undergoing oncological treatment. These disruptions are often associated with aggravated symptom burden and diminished health-related quality of life that in turn may compromise treatment adherence and, thus, effectiveness. In addition, disrupted sleep has been linked to carcinogenic processes, which ultimately could result in worse prognostic outcomes.

Systematic Review: Sleep Disorders Based on Objective Data in Children and Adolescents Treated for a Brain Tumor.

Background: Tumors of the central nervous system (CNS) are the most common solid childhood malignancy. Over the last decades, treatment developments have strongly contributed to the improved overall 5-year survival rate, which is now approaching 75%. However, children now face significant long-term morbidity with late-effects including sleep disorders that may have detrimental impact on everyday functioning and quality of life.

Cognitive impairment following radiation to hippocampus and other brain structures in adults with primary brain tumours.

Background: Radiation therapy (RT) to the brain may result in cognitive impairment. The primary objective of the present study was to examine the relationship between RT dose to the hippocampus and learning and memory functions. Secondary objective was to examine relationships between doses to other brain structures and specific cognitive functions.

Feasibility and Preliminary Efficacy of a Bright Light Intervention in Ovarian and Endometrial Cancer Survivors.

Background: Cancer-related sleep disturbance is common and can adversely affect physical and mental health. Bright light (BL) therapy is a novel intervention that targets sleep by promoting circadian regulation. Emerging evidence suggests BL can improve sleep disturbance, symptom burden, and health-related quality of life in cancer and other populations; however, this research is limited.

Long-term cognitive dysfunction after radiation therapy for primary brain tumors.

The extent of radiation therapy (RT)-induced changes in cognitive function is unknown. RT with protons instead of photons spares the healthy brain tissue more and is believed to reduce the risk of cognitive dysfunction. There is modest knowledge on which parts of the brain we need to spare, to prevent cognitive dysfunction.

Longitudinal dyadic associations of fear of cancer recurrence and the impact of treatment in prostate cancer patients and their spouses.

Fear of cancer recurrence (FCR) in patients and their spouses is associated with reduced quality of life, but little is known about longitudinal dyadic associations of FCR between them. This study examined (i) the trajectory of FCR from pre-treatment to 12 months later; (ii) dyadic associations of FCR over time; and (iii) whether cancer treatment type predicted later FCR among prostate cancer patients and their spouses. Sixty-nine patients and 71 spouses of patients with localized prostate cancer completed a FCR measure at baseline (pre-treatment), 6 months and 12 months later (post-treatment).

Structural brain alterations following adult non-CNS cancers: a systematic review of the neuroimaging literature.

Cancer and cancer treatments may impact the brain through several pathways leading to cognitive impairment. Neuroimaging evidence has begun to elucidate the neurobiological underpinnings of cancer-related cognitive impairment. The aim of this paper was to systematically review available literature on structural brain alterations following adult non-central nervous system (CNS) cancers and associated treatments.

A mixed methods analysis of perceived cognitive impairment in hematopoietic stem cell transplant survivors.

Objective: Hematopoietic stem cell transplant (HSCT) survivors may show evidence of objective cognitive impairment; however, perceived cognitive problems and their impact on quality of life are less well-understood. The purpose of this study was to explore HSCT survivors' perceptions of cognitive impairment and its effect on daily life functioning.

Method: Sixty-nine autologous and allogeneic HSCT survivors nine months to three years posttransplant experiencing mild survivorship problems completed a brief structured interview regarding perceived cognitive impairment since transplant.

Programmed environmental illumination during autologous stem cell transplantation hospitalization for the treatment of multiple myeloma reduces severity of depression: A preliminary randomized controlled trial.

Background: Over a third of multiple myeloma (MM) patients report clinical levels of depression during autologous stem cell transplant (ASCT) hospitalization. We report preliminary results from a randomized clinical trial investigating the effect of Programmed Environmental Illumination (PEI) of hospital rooms on depression.

Methods: Patients (N = 187) scheduled to receive an ASCT were assessed for eligibility.

Changes in Brain Structural Networks and Cognitive Functions in Testicular Cancer Patients Receiving Cisplatin-Based Chemotherapy.

Background: Cisplatin-based chemotherapy may have neurotoxic effects within the central nervous system. The aims of this study were 1) to longitudinally investigate the impact of cisplatin-based chemotherapy on whole-brain networks in testicular cancer patients undergoing treatment and 2) to explore whether possible changes are related to decline in cognitive functioning.

Methods: Sixty-four newly orchiectomized TC patients underwent structural magnetic resonance imaging (T1-weighted and diffusion-weighted imaging) and cognitive testing at baseline prior to further treatment and again at a six-month follow-up.

Computerized cognitive training in prostate cancer patients on androgen deprivation therapy: a pilot study.

Purpose: Prostate cancer patients who have undergone androgen deprivation therapy (ADT) may experience cognitive impairment, yet there is an unmet need for nonpharmacological interventions to address cognitive impairment in this population. This study examines the feasibility, acceptability, and preliminary efficacy of a home-based computerized cognitive training (CCT) program to treat cancer-related cognitive impairment.

Methods: Sixty men who had received ≥ 3 months of ADT were screened for at least mild cognitive or neurobehavioral impairment and randomized to 8 weeks of CCT or usual care.

The Effect of Systematic Light Exposure on Sleep in a Mixed Group of Fatigued Cancer Survivors.

Study Objectives: Sleep disturbances are commonly reported by cancer survivors. Systematic light exposure using bright light has been used to improve sleep in other populations. In this secondary data analysis, the effect of morning administration of bright light on sleep and sleep quality was examined in a mixed group of fatigued cancer survivors.

Personal resilience resources predict post-stem cell transplant cancer survivors' psychological outcomes through reductions in depressive symptoms and meaning-making.

This longitudinal study examined whether post-transplant cancer survivors (N = 254, 9 months to 3 years after stem cell transplant treatment) with greater personal resilience resources demonstrated better psychological outcomes and whether this could be attributed to reductions in depressive symptoms and/or four meaning-making processes (searching for and finding reasons for one's illness; searching for and finding benefit from illness). Hierarchical linear regression analyses examined associations of survivors' baseline personal resilience resources (composite variable of self-esteem, mastery, and optimism), which occurred an average of 1.7 years after transplant, and 4-month changes in psychological outcomes highly relevant to recovering from this difficult and potentially traumatic treatment: post-traumatic stress disorder (PTSD) symptoms and purpose in life.
