Can Multidisciplinary Inpatient and Outpatient Rehabilitation Provide Sufficient Prevention of Disability in Patients with a Brain Tumor?-A Case-Series Report of Two Programs and A Prospective, Observational Clinical Trial

Impact of Cognitive Rehabilitation on Cognitive and Functional Outcomes in Adult Cancer Survivors: A Systematic Review

OBJECTIVES

This systematic review (PROSPERO CRD42021275421) synthesized evidence on the efficacy of cognitive rehabilitation on cognitive and functional outcomes in adult cancer survivors.

METHODS

Articles were identified though PubMed/MEDLINE, EMBASE, PsycINFO, and Web of Science from inception through June 30, 2023. Studies included participants ≥18 years old, diagnosed with cancer. Primary outcomes were validated measures of subjective and objective cognition. Articles were dual reviewed for eligibility and data extraction. Risk of bias was assessed with the Standard Quality Assessment Criteria for Evaluating Primary Research Papers from a Variety of Fields.

RESULTS

The search yielded 3,811 articles; 65 full-text articles were reviewed; 53 articles (15 cognitive training, 14 strategy-based, 21 combinations, three inpatient rehabilitation), representing 52 unique studies, were included. Positive effects were observed in at least one objective cognitive measure in 93% of strategy training, 81% of cognitive training, 79% of combination rehabilitation interventions. Positive effects were observed in subjective cognition in 100% of strategy training, 55% of cognitive training, and 92% of combination interventions. Among studies with comparator groups, processing speed improved in 60% of cognitive training studies, while strategy training did not improve processing speed; otherwise, cognitive domain effects were similar between intervention types. Impact on functional outcomes was inconclusive.

CONCLUSIONS

Cognitive rehabilitation appear beneficial for cancer-related cognitive impairment (CRCI). Differential effects on specific cognitive domains (eg, processing speed) and subjective cognition may exist between intervention types.

IMPLICATIONS FOR NURSING PRACTICE

Nurses should increase patient and provider awareness of the benefits of cognitive rehabilitation for CRCI.

Neural and Onconeural Autoantibodies and Blood-Brain Barrier Disruption Markers in Patients Undergoing Radiotherapy for High-Grade Primary Brain Tumour

Radiotherapy (RT) plays a key role in brain tumours but can negatively impact functional outcomes and quality of life. The aim of this study was to analyse anti-neural and onconeural autoantibodies and markers of blood-brain barrier (BBB) disruption in patients with primary brain cancer undergoing RT.

MATERIALS AND METHODS

A prospective study was conducted on 45 patients with a brain tumour scheduled for intensity-modulated radiotherapy. Assessments were performed at baseline, post-RT, and at three months. We measured serum levels of BBB disruption biomarkers and anti-neural, onconeural, and organ-specific antibodies.

RESULTS

Antibodies against nucleosome antigens and neuronal surface antigens were detected in 85% and 3% of cases, respectively; anti-neural and onconeural antibodies were observed in 47% and 5.8%. In 44% patients, ≥2 antibody types were detected. No significant changes in BBB biomarkers were observed.

CONCLUSION

The findings of this study show that a humoral immune response is common in patients undergoing RT for brain cancer. This response appears to be non-organ specific but rather directed against nucleosome antigens, but onconeural antibodies were uncommon, suggesting a low risk of a neurological paraneoplastic syndrome. Our data suggested that radiotherapy may not affect BBB integrity, but larger studies are needed to better characterise the pathophysiological effects of RT.

Rehabilitation Exercises Supported by Monitor-Augmented Reality for Patients with High-Grade Glioma Undergoing Radiotherapy: Results of a Randomized Clinical Trial

BACKGROUND

Exercise has been shown to improve quality of life (QoL) and even treatment outcomes in cancer patients. However, the evidence to support the benefits of exercise in patients with high-grade glioma (HGG) is limited. Therefore, we performed a randomized clinical trial (RCT) to examine the effect of augmented-reality-based rehabilitation exercises on physical and functional fitness, cognitive function, fatigue, mood, QoL, selected blood parameters, brain derived neurotrophic factor (BDNF), and S100 protein in patients with HGG.

METHODS

Adult patients with HGG scheduled to undergo radiotherapy after tumor resection were randomized to participate in an exercise program (experimental group, n = 25) or to receive usual care (controls, n = 22). Physical and mental fitness was measured at baseline, after the completion of radiotherapy, and at 3 months. The following tests were administered: Handgrip Strength Test; 6-Minute Walk Test; Time Up and Go test; Functional Independent Measure scale; Addenbrooke's Cognitive Examination III (ACE III); Hospital Anxiety and Depression Scale; Functional Cancer Therapy Assessment-Brain; and Functional Assessment of Chronic Illness Therapy-Fatigue. We also measured blood parameters, BDNF, and S100 protein levels.

RESULTS

No significant changes were observed in the exercise group. However, the controls experienced a significant decrease in HGS and in the ACE III attention domain. No significant changes were observed in QoL, fatigue, BDNF, or S100 levels in either group.

CONCLUSIONS

Augmented-reality-based exercise during radiation therapy may prevent loss of muscle strength and attention in patients with HGG.

Psychological Characteristics Associated with Post-Treatment Physical Status and Quality of Life in Patients with Brain Tumor Undergoing Radiotherapy

Radiotherapy (RT) is a mainstay of treatment for brain tumors. To minimize the risk of side effects while maximizing the therapeutic effects, personalized treatment plans, consisting mainly of genomics, radiomics, and mathematical modeling, are increasingly being used. We hypothesize that personality characteristics could influence treatment outcomes and thus could be used to help personalize RT. Therefore, the aim of this study was to identify the psychological characteristics associated with post-treatment physical status and quality of life (QoL) in patients with brain tumors undergoing RT. Two psychological tests-the Eysenck Personality Questionnaire and the State-Trait Anxiety Inventory-were administered prior to RT. Physical parameters before and after RT were also assessed through the following tests: hand grip strength, Timed Up and Go test, 6 Min Walk Test, and Functional Independence Measure. The Functional Assessment of Cancer Therapy-General (FACT-G) was used to assess QoL. The Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) was administered to assess fatigue. Neuroticism was significantly associated with low FACT-G Physical Well-Being scores. Psychoticism was associated with an improvement in physical fitness scores after RT. These findings suggest that personality traits should be considered when designing a personalized radiotherapy plan.

Predictors of functional outcomes in adults with brain tumor undergoing rehabilitation treatment: a systematic review

INTRODUCTION

The number of diagnosed brain tumors (BT) has increased in recent years. The results of treatment of patients with surgery, chemotherapy and radiotherapy are also improving and their survival rate has increased significantly. Symptoms of the disease and side effects of oncological treatment may reduce the functional performance of patients. It is so important to conduct rehabilitation in this group of patients. The aim of this systematic review is to identify predictors of effective rehabilitation in aspects of physical functioning of BT patients. The study was registered with health and social care, welfare, public health, education, crime, justice and international development departments, where there is a health-related interest outcome PROSPERO. We have received registration number is: CRD42021269398.

EVIDENCE ACQUISITION

To find relevant publications, the algorithm of keywords ("brain tumor") AND (rehabilitation OR "physical activity" OR exercise OR "physical therapy") was used. The search was conducted in PubMed, Web of Science, PEDro, ClinicalTrials.gov and Cochrane Library. Information was extracted using the PICO format (i.e., participants, intervention, comparison, outcomes).

EVIDENCE SYNTHESIS

the initial search identified a total of 1122 results, and 21 articles met the criteria and were selected for analysis.

CONCLUSIONS

The results present that rehabilitation is an important and safe cancer encouraging therapy, brings functional benefits. The type of rehabilitation program, especially in BT patients, depends on many factors such as time and type of oncological treatment, general conditions which is strongly related to the general functioning of the patient. It still is a need for clinical research into the safety and effectiveness of rehabilitation interventions already during radio or chemotherapy in this group of cancer patients.
