Supportive effect of Viscum album L. extracts on the sense of coherence in non-metastasized breast cancer patients

Validation of the Internal Coherence Scale (ICS) in Healthy Geriatric Individuals and Patients Suffering from Diabetes Mellitus Type 2 and Cancer

BACKGROUND

With increased life expectancy, the coexistence of functional impairment and multimorbidity can negatively impact life quality and coherence in geriatric individuals. The self-report 10-item Internal Coherence (ICS) measures how individuals cope with and make sense of disease-specific life challenges. The aim of this study was to validate the ICS in a sample of geriatric individuals.

METHODS AND PROCEDURE

In a cross-sectional study, geriatric individuals with and without chronic diseases were recruited. A factor analysis with principal component extraction (PCA) and a structural equation model (SEM) was conducted to assess the ICS factor structure in a geriatric sample. To measure convergent validity, the following scales were used: Short Health Survey (SF-12), Karnofsky Performance Index (KPI), Trait autonomic regulation (Trait aR), Sense of Coherence Scale (SOC), and Geriatric Depression Scale (GDS).

RESULTS

A sample of n = 104 (70-96 years of age) patients with Diabetes Mellitus Type 2 (n = 22), cancer diseases (n = 31) and healthy controls (n = 51) completed the ICS. PCA and SEM yielded the original two-factor solution: 1. Inner resilience and coherence and 2. Thermo coherence. Overall internal consistency for this cohort was satisfying (Cronbach's α with rα = 0.72), and test-retest reliability was moderate (rrt = 0.53). ICS scores were significantly correlated to all convergent criteria ranging between r = 0.22 * and 0.49 ** (p < 0.05 *; p < 0.01 **).

CONCLUSION

Study results suggest that the ICS appears to be a reliable and valid tool to measure internal coherence in a geriatric cohort (70-96 years). However, moderate test-retest reliability prompts the consideration of potential age-effects that may bias the reliability for this specific cohort.

Systematic analysis of mistletoe prescriptions in clinical studies

Purpose

Mistletoe treatment is discussed controversial as a complementary treatment for cancer patients. Aim of this systematic analysis is to assess the concept of mistletoe treatment in the clinical studies with respect to indication, type of mistletoe preparation, treatment schedule, aim of treatment, and assessment of treatment results.

Methods

In the period from August to December 2020, the following databases were systematically searched: Medline, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), PsycINFO, CINAHL, and “Science Citation Index Expanded” (Web of Science). We assessed all studies for study types, methods, endpoints and mistletoe preparations including their ways of application, host trees and dosage schedules.

Results

The search concerning mistletoe therapy revealed 3296 hits. Of these, 102 publications and at total of 19.441 patients were included. We included several study types investigating the application of mistletoe in different groups of participants (cancer patients of any type of cancer were included as well as studies conducted with healthy volunteers and pediatric patients). The most common types of cancer were breast cancer, pancreatic cancer, colorectal cancer and malignant melanoma. Randomized controlled studies, cohort studies and case reports make up most of the included studies. A huge variety was observed concerning type and composition of mistletoe extracts (differing pharmaceutical companies and host trees), ways of applications and dosage schedules. Administration varied e. g. between using mistletoe extract as sole treatment and as concomitant therapy to cancer treatment. As the analysis of all studies shows, there is no relationship between mistletoe preparation used, host tree and dosage, and cancer type.

Conclusions

Our research was not able to deviate transparent rules or guidelines with respect to mistletoe treatment in cancer care.

Exploring the resources of the genus Viscum for potential therapeutic applications

ETHNOPHARMACOLOGICAL RELEVANCE

The genus Viscum comprises approximately 100 species that are mainly distributed across Africa, Asia and Europe. The extracts and preparations of Viscum species are widely used as common complementary and alternative medicines in the treatment of rheumatism and cancer.

AIM OF THE REVIEW

This review aims to explore the medicinal properties of twelve species belonging to the genus Viscum for potential therapeutic applications.

MATERIALS AND METHODS

We collected online information (including PubMed, CNKI, Google Scholar, and Web of Science) from January 1915 to April 2021 and knowledge from classical books on Chinese herbal medicines available for 12 species of the genus Viscum, including Viscum coloratum (Kom.) Nakai, Viscum album L., Viscum articulatum Burm. f., Viscum liquidambaricola Hayata, Viscum ovalifolium DC., Viscum capitellatum Sm., Viscum cruciatum Sieber ex Boiss., Viscum nudum Danser, Viscum angulatum B.Heyne ex DC., Viscum tuberculatum A.Rich., Viscum multinerve Hayata, and Viscum diospyrosicola Hayata.

RESULTS

At least 250 different compounds have been reported across twelve Viscum species, including amino acid and peptides, alkaloids, phenolic acids, flavonoids, terpenoids, carbohydrates, fatty acids, lipids, and other types of compounds. In particular, for Viscum coloratum (Kom.) Nakai and Viscum album L., the plants, preparations, and bioactive components have been thoroughly reviewed. This has allowed to elucidate the role of active components, including lectins, viscotoxins, flavonoids, terpenoids, phenolic acids, and polysaccharides, in multiple bioactivities, such as anti-cancer, anti-rheumatism arthralgia, anti-inflammation, anti-cardiovascular diseases, enhancing immunity, and anti-chemotherapy side effects. We also evaluated quality control methods based on active compounds, in vivo exposure compounds, and discriminated chemical markers.

CONCLUSIONS

This is the first report to systematically review the pharmaceutical development history, chemical composition, clinical evidence, pharmacological activity, discriminated chemical markers, in vivo exposure, and quality control on twelve distinct species of Viscum plants with medicinal properties. The significant safety and efficacy, along with the minor side effects are constantly confirmed in clinics. The genus Viscum is thus an important medicinal resource that is worth exploring and developing in future pharmacological and chemical studies.

Impact of Oncological Therapy and Viscum album L Treatment on Cancer-Related Fatigue and Internal Coherence in Nonmetastasized Breast Cancer Patients

Introduction:Viscum album L extracts (VA) are frequently used in integrative oncology. Aim of this study was to evaluate the impact of add-on VA applications on various patient-reported outcome measures. Methods: A longitudinal real-world study was conducted, using data from the Network Oncology clinical registry. Primary, nonmetastasized breast cancer patients treated with oncological standard therapy partly combined with VA applications were included. Internal Coherence Cancer-related Fatigue, and EORTC QLQ-C30 questionnaires were assessed at baseline and 6, 12, and 24 months later. Results: A total of 319 patients received standard oncological therapy and 40% of them additionally VA applications. After 6 and 12 months for patients treated with chemotherapy (Ctx) only a significant decline of the thermo-coherence, and worsening of fatigue was observed. For patients receiving VA applications but no Ctx, significant beneficial effects on thermo-coherence, fatigue, and seven EORTC QLQ-C30 scales were observed 24 months later. Adjusted multivariable long-term subgroup (n = 106) regression analysis revealed that Ctx, immuno-, and endocrine therapies had a worsening of 17, 17, and 6 point changes, respectively, for EORTC QLQ-C30 fatigue (P = .0004), while VA applications showed an improvement of 12 point change. A similar impact of improvement (add-on VA) and worsening (standard oncological treatment regimens) on EORTC QLQ-C30 insomnia (P = .009) and physical functioning (P = .005) were observed. Conclusions: In the present real-world study, add-on VA applications had a supportive effect on cancer-related fatigue, insomnia, physical functioning, and thermo-coherence. Thus, VA applications might be suited to alleviate symptom burden during anticancer therapy in breast cancer patients.

Assessment of integrative non-pharmacological interventions and quality of life in breast cancer patients using real-world data

BACKGROUND

Treatments with non-pharmacological interventions (NPIs), comprising art and exercise therapies, nursing interventions, and educational components, are considered to improve quality of life of cancer patients. The aim of this study was to assess the longitudinal changes in self-reported quality of life of breast cancer patients receiving an integrative medicine program consisting of hospital-based NPIs and standard oncological treatments.

METHODS

This real-world data study was conducted using data from the Network Oncology clinical registry of the Gemeinschaftskrankenhaus Havelhöhe. Primary breast cancer patients of all tumor stages, who answered the European Organization of Research and Treatment Health-Related Quality of Life Core Questionnaire scale (EORTC QLQ-C30) at first diagnosis and 12 months later, were included. Association factors between received NPIs and longitudinal EORTC QLQ-C30-changes were analyzed with additive non-parametric regression tests, considering treatment regimens and demographic variables, using the software R.

RESULTS

A total of 231 primary breast cancer patients were enrolled and separate regression analyses were carried out. Significant associations between the received NPIs elaborate consultations and life review, nursing compresses, music and eurythmy therapy and improvements of 8-13 points for global health, all five functional EORTC-scales, and symptoms fatigue, dyspnea, insomnia, and financial difficulties were observed.

CONCLUSION

Our findings support the beneficial impact of NPIs for breast cancer patients. Further research could be directed towards synergistic effects of multimodal applied NPIs.

Evaluation of the effects of integrative non-pharmacological interventions on the internal coherence and resilience of breast cancer patients

PURPOSE

In the breast cancer center at the Gemeinschaftskrankenhaus Havelhöhe (GKH), integrative strategies are implemented in the routine care of breast cancer patients. The aim of this breast cancer real-world study was to systematically evaluate changes in patients' internal coherence and resilience, associated with the use of non-pharmacological interventions (NPIs).

METHODS

This study included 231 primary breast cancer patients treated with standard oncological therapy and NPIs, which comprise art and movement therapies, nursing interventions, and educational components, and had answered the internal coherence scale (ICS) questionnaire at first diagnosis and 12 months later. Data were collected from the Network Oncology clinical registry of the GKH, and effects of NPIs on ICS changes were analyzed with adjusted linear multivariable regression analyses, using the software R.

RESULTS

Two hundred twenty breast cancer patients of all tumor stages were eligible for a total of 27 separate adjusted multivariable linear regression analyses. The NPIs elaborate consultations and life review (ECLR); nursing compresses, music therapy, and rhythmic massages were significantly associated with increases of about 2-point changes in inner resilience and coherence (p < 0.05). Furthermore, a significant association with an elevation of the thermo coherence was observed for the application of nursing compresses.

CONCLUSIONS

The evaluation of real-world data carried out here shows that the application of the multimodal treatment concept can lead to an enhancement of the internal coherence and resilience in breast cancer patients. To improve the care of cancer patients, this multimodal program should be further expanded into routine clinical practices.

Analysis of Changes in Cancer-Related Fatigue of Breast Cancer Patients Receiving an Integrative Medicine Program

INTRODUCTION

Cancer-related fatigue (CRF) occurs frequently in breast cancer patients. The aim of this real-world study was to analyze the longitudinal changes of CRF in breast cancer patients receiving an integrative medicine program, which includes the application of non-pharmacological interventions (NPIs) and Viscum album L. (VA) extracts.

METHODS

All data were collected from the clinical register of the Network Oncology of a German certified breast cancer center of the Gemeinschaftskrankenhaus Havelhöhe (GKH). Primary breast cancer patients, treated upon initial diagnosis with integrated NPIs, comprising art and exercise therapy, nursing interventions, and educational components, during their hospital stay, and who had answered the German Cancer-Fatigue Scale (CFS-D) questionnaire at first diagnosis and 12 months later, were included. The associations between NPIs and CFS-D changes were analyzed with adjusted multivariable regression analyses, considering received treatment regimens and demographic variables, using the software R.

RESULTS

231 female breast cancer patients of all tumor stages were evaluated. While chemotherapy exhibited significant severe deterioration, add-on VA applications seem to partially mitigate this impairment on CRF. 36 separate multivariable regression analyses for all NPIs showed that in particular significant associations between CFS-D improvements and the interventions nursing compresses (6 point change; P = .0002; R² = 28%) or elaborate consultations and life review (ECLR) (4 point change; P = .0002; R² = 25%) were observed.

CONCLUSIONS

Breast cancer patients benefit from a hospital-based integrative medicine program. To alleviate fatigue symptoms during oncological therapy, an expansion of this concept should be developed in the future.
