Trajectories of Symptom Clusters, Performance Status, and Quality of Life During Concurrent Chemoradiotherapy in Patients With High-Grade Brain Cancers

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.

The Mediating Effect of Uncertainty in Illness on Cancer Coping in Patients With Primary Malignant Brain Tumors

BACKGROUND

Patients with primary malignant brain tumors (PMBTs) experience uncertainty in illness (UI) because of the high recurrence rate and symptoms that occur during treatment.

OBJECTIVE

To develop and test a model based on the Uncertainty in Illness Theory to predict the UI and cancer coping experienced by PMBT patients.

METHODS

This was a cross-sectional study using path analysis. The participants were adults diagnosed with PMBT who completed a questionnaire about demographic and disease-related characteristics, UI, cancer coping, brain tumor symptoms, and social support. Clinical data (eg, the diagnosis, tumor location, and grade) were obtained from electronic health records. Data were analyzed using SPSS 26.0 and the MVN , psych , and lavaan packages in R 4.1.0.

RESULTS

This study included 203 PMBT patients. The hypothesized model satisfied all statistical criteria (comparative fit index = 0.998, root mean square error of approximation = 0.044, standardized root mean square residual = 0.016). The indirect and direct associations of UI in the path from social support to cancer coping were all significant with a 95% bootstrapping confidence interval. Although the indirect and direct associations of UI in the path of brain tumor symptoms and cancer coping did not have direct or total effects, the indirect effect was statistically significant.

CONCLUSIONS

Uncertainty in illness mediated brain tumor symptoms and social support to predict cancer coping.

IMPLICATIONS FOR PRACTICE

A nurse-led intervention for cancer coping among PMBT patients can be developed by considering symptoms and social support and UI as a mediator.

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.

Symptom management in adult brain tumours: A literature review

AIM

To review the literature related to symptom management, clinical significance and related theoretical framework systems in adult patients with brain tumours.

BACKGROUND

As understanding of symptoms or symptom clusters and underlying biologic mechanisms has grown, it is apparent that symptom science is moving forward. Although some progress has been made in the symptom science of solid tumours such as breast and lung neoplasms, insufficient attention has been paid to symptom management for patients suffering from brain tumours. Further research is needed to achieve effective symptom management for these patients.

DESIGN

A literature review with a systematic search of symptom management in adult brain tumours.

METHODS

Electronic data bases were searched to obtain relevant published literature on symptom management in adults with brain tumours. This was then analysed and a synthesis of relevant findings is presented.

FINDINGS

Four significant general themes relating to symptom management of brain tumours in adults were identified: (1) The potential theoretical foundation related to symptom management was revealed. (2) Widely accepted validated scales or questionnaires for the assessment of single symptoms or symptom clusters were recommended. (3) Several symptom clusters and the underlying biologic mechanisms have been reported. (4) Specific symptom interventions for adults with brain tumours were collected and classified as evidence-based or insufficient evidence.

CONCLUSION

There are still many challenges in the effective management of symptoms in adults with brain tumours. The guiding role of theoretical frameworks or models related to symptom management should be utilized in future research. Using the concept of symptom clustering for research into symptoms found in patients with brain tumours, exploring common biological mechanisms for specific symptom clusters and making full use of modern big data resources to build a strong evidence base for an effective intervention or management program may inform the management of symptoms among these patients leading to better results.

NO PATIENT OR PUBLIC CONTRIBUTION

This is a literature review.

IMPLICATIONS FOR SYMPTOM MANAGEMENT

The ultimate goal is obviously not only improving the survival rate of patients with brain tumours, but also enhancing their quality of life. Several important findings from our review include the theoretical foundations, validated assessment tools, the assessment of symptom clusters and the underlying biologic mechanism, and the identification of the evidence base for symptom interventions. These are of relevance for managers, researchers and practitioners and may function as a reference to help the effective symptom management for adults with brain tumours.

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.

Symptom clusters change over time among patients with gynecological cancer receiving chemotherapy

PURPOSE

This study aimed to explore symptom clusters at different time points among patients with gynecological cancer undergoing chemotherapy.

METHODS

A longitudinal design was used to explore the patterns of symptom clusters four times: during prechemotherapy (T0), first (T1), second (T2), and third (T3) cycles of chemotherapy. The Memorial Symptom Assessment Scale was used to assess the dimension of symptoms. The study was conducted in Indonesia. Exploratory factor analysis was used to analyze the structures of symptom clusters across time.

RESULTS

A total of 120 subjects provided baseline data, and 82 were retained at T3. Before chemotherapy, the most prevalent symptoms were pain and difficulty in sleeping. However, after starting chemotherapy, the patients suffered from chemotherapy-related side effects, including nausea, change in taste, lack of appetite, hair loss, fatigue, and feeling of "I don't look like myself." Six symptom clusters were identified in patients with gynecological cancer across four time points during chemotherapy: pain-related, nutritional, emotional, hormonal-related, fatigue-related, and body-image symptom clusters. Nutrition and emotion symptom clusters occurred consistently from T0 to T3, fatigue-related clusters appeared after chemotherapy at T1 and T2, and body-image symptom clusters emerged at late T2 and T3.

CONCLUSION

The structures of symptom clusters in this study were dynamic and various. The nutrition and emotional-related symptoms constituted a cluster during chemotherapy. Oncology nurses should provide physical and psychosocial interventions to relieve these symptoms in patients with gynecological cancer undergoing chemotherapy.

Factors influencing quality of life among childhood cancer survivors in Korea: A quantile regression approach

Cancer treatment in childhood may negatively affect survivors' quality of life. In this study, we aimed to determine the contributing factors for health-related quality of life (HRQOL) in survivors of childhood cancer in Korea using quantile regression analysis. This study was a secondary analysis. Data were collected from 130 childhood cancer survivors (CCS) from November 2018 to July 2019. Participants completed the Memorial Symptom Assessment Scale, Depression Anxiety Stress Scale, Health-Promoting Lifestyle Profile-II, and 36-Item Short Form Health Survey (physical component summary [PCS] and mental component summary [MCS]). Quantile and multiple linear regressions were used to analyze the factors contributing to HRQOL. The quantile and linear regression models revealed different results on the contributing factors to HRQOL in CCS. Mean PCS and MCS scores were 78.55 (SD = 15.08) and 64.02 (SD = 18.00), respectively. Symptoms (e.g., difficulty concentrating, worrying, pain, and lack of energy), physical activity, spiritual growth, interpersonal relationships, stress management, depression, and anxiety were significant influencing factors in some PCS quantiles, while symptoms, spiritual growth, interpersonal relationships, depression, and stress were significant influencing factors in some MCS quantiles. The findings of this study showed specific contributing factors in CCS with different levels of HRQOL. There is a need for targeted interventions related to risk reduction and stratification for CCS with different HRQOL levels. Symptom management strategies, early detection programs for CCS with psychological distress, and clinical and counseling interventions for CCS with poor HRQOL need to be developed.

Determination of Self-Efficacy, Body Image and Sexual Adjustment of Women with Breast Cancer

Objective

The determination of the self-efficacy levels of women with breast cancer, as well as their body image (BI) and sexual adjustment status, is very important for their empowerment. The purpose of this study was to determine the self-efficacy, BI, and sexual adjustment levels of women with breast cancer that received chemotherapy, as well as the factors that influence these characteristics.

Materials and Methods

This descriptive study included women (n=117) that were diagnosed with breast cancer, had received at least two sessions of chemotherapy. The study data were collected using a sociodemographic form which also included questions about the breast cancer. Also, the Strategies Used by Patients to Promote Health (SUPPH) scale, and the Sexual Adjustment and Body Image Scale (SABIS) were used.

Results

The average age of the women participating in the study was 56.64±8.78 years. In the study, the women with breast cancer undergone a mastectomy, and those who lacked the support of their spouses, as well as education on sexuality, obtained lower scores on the SUPPH and SABIS. There was a positive correlation between the self-efficacy in self-care and sexual adjustment, sexual functions, and body images.

Conclusion

This study found that the women with breast cancer had low self-efficacy, and that their former sexual adjustment and low body image had a negative effect on their post-diagnosis sexual functions.

The Correlation of Symptom Clusters and Functional Performance in Adult Acute Leukemia Patients Under Chemotherapy

BACKGROUND

Adult acute leukemia (AL) patients who receive chemotherapy usually experience multiple symptoms during the treatment course. The symptom clusters (SCs) as well as subsets of concurrent symptoms in AL patients have not yet been demonstrated.

OBJECTIVE

To investigate the SCs of adult AL patients who were receiving chemotherapy and to determine their correlations with functional performance.

METHODS

A total of 132 hospitalized adult AL patients were included in this study. A cross-sectional survey aimed to examine symptoms and functional performance was conducted. The patients' symptoms were assessed using the Chinese version of the Condensed Memorial Symptom Assessment Scale, and functional performance was evaluated through activities of daily living and quality of life.

RESULTS

We identified 4 SCs in adult AL patients: psychological SC, pain-fatigue-sleep SC, dry mouth-constipation SC, and nutrition-impaired SC. The psychological SC was the most common and most distressing SC. The different SCs were each differentially correlated with patient characteristics. The distress of the psychological SC, pain-fatigue-sleep SC, and nutrition-impaired SC was adversely correlated with functional performance.

CONCLUSIONS

Adult AL patients undergoing chemotherapy experience multiple symptoms that can be further categorized into 4 SCs. The distress from some SCs is negatively associated with patients' functional performance.

IMPLICATIONS FOR PRACTICE

Symptom burden remains a major problem for adult AL patients undergoing chemotherapy. Identifying SCs of AL patients should be the basis for accurate and cost-effective interventions. Personalized SC management may improve the functional performance and healthcare quality of adult AL patients.

Sensory changes and lipoprotein ratios in patients with brain cancers during cancer-related therapy: A prospective cross-sectional study

AIM

To identify the sensory changes and lipoprotein ratios and their relationship in brain cancer patients during cancer-related therapy (CRT).

METHODS

This was a prospective cross-sectional study with three observation times: before CRT, at 2-3 weeks, and 4-6 weeks after beginning CRT. The changes in patients' symptoms were evaluated using the Memorial Symptom Assessment Scale, and lipoprotein ratios were measured using total cholesterol/ high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol/HDL-c, and triglyceride/HDL-c at the three time points.

RESULTS

Sensory changes such as itching, swelling of the arms and legs, numbness in the hands or feet, tingling in the hands or feet, and changes in the way food tastes and lipoprotein ratios were altered in patients with brain cancer during CRT. The lipoprotein ratios showed a significant positive correlation with sensory changes at each observation time (p < .05).

CONCLUSION

Sensory changes and lipoprotein ratios varied, and their significant relationship was identified during CRT. Lipoprotein ratios should be considered as an indicator for symptom management in patients with malignant brain cancer during CRT.
