[PMID: 38672690 PMCID: PMC11049173 DOI: 10.3390/cancers16081609] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Revised: 04/09/2024] [Accepted: 04/17/2024] [Indexed: 04/28/2024] Open
Abstract
Immunotherapy with PD-1/PD-L1 inhibitors has significantly improved the survival rates of patients with metastatic non-small-cell lung cancer (NSCLC). Results of a real-world data study investigating add-on VA (Viscum album L.) to chemotherapy have shown an association with the improved overall survival of patients with NSCLC. We sought to investigate whether the addition of VA to PD-1/PD-L1 inhibitors in patients with advanced or metastasised NSCLC would have an additional survival benefit. In the present real-world data study, we enrolled patients from the accredited national registry, Network Oncology, with advanced or metastasised NSCLC. The reporting of data was performed in accordance with the ESMO-GROW criteria for the optimal reporting of oncological real-world evidence (RWE) studies. Overall survival was compared between patients receiving PD-1/PD-L1 inhibitor therapy (control, CTRL group) versus the combination of anti-PD-1/PD-L1 therapy and VA (combination, COMB group). An adjusted multivariate Cox proportional hazard analysis was performed to investigate variables associated with survival. From 31 July 2015 to 9 May 2023, 415 patients with a median age of 68 years and a male/female ratio of 1.2 were treated with anti-PD-1/PD-L1 therapy with or without add-on VA. Survival analyses included 222 (53.5%) patients within the CRTL group and 193 (46.5%) in the COMB group. Patients in the COMB group revealed a median survival of 13.8 months and patients in the CRTL group a median survival of 6.8 months (adjusted hazard ratio, aHR: 0.60, 95% CI: 0.43-0.85, p = 0.004) after adjustment for age, gender, tumour stage, BMI, ECOG status, oncological treatment, and PD-L1 tumour proportion score. A reduction in the adjusted hazard of death by 56% was seen with the addition of VA (aHR 0.44, 95% CI: 0.26-0.74, p = 0.002) in patients with PD-L1-positive tumours (tumour proportion score > 1%) treated with first-line anti-PD-1/PD-L1 therapy. Our findings suggest that add-on VA correlates with improved survival in patients with advanced or metastasised NSCLC who were treated with PD-1/PD-L1 inhibitors irrespective of age, gender, tumour stage, or oncological treatment. The underlying mechanisms may include the synergistic modulation of the immune response. A limitation of this study is the observational non-randomised study design, which only allows limited conclusions to be drawn and prospective randomised trials are warranted.

Abstract
PURPOSE OF REVIEW The goal of this review was to examine the role and practical applications of integrative oncology strategies in supporting immune checkpoint inhibitor (ICI) treatment of adult solid tumours. RECENT FINDINGS Beyond tumour-intrinsic factors, several patient-associated factors affect ICI response, including germline genetics, systemic inflammation, the gut microbiota, and diet. Current promising supportive interventions include a Mediterranean-style diet with over 20 g of fibre, regular exercise, use of live biotherapeutics, minimisation of PPI and antibiotic use, and ensuring vitamin D repletion, with many other integrative oncology approaches under study. Caution around medical cannabis use in patients on ICIs is advised due to previously documented adverse impact on overall survival, while VAE (Viscum album extract) therapy studies have not highlighted any safety concerns so far. With expanding ICI use, it is important to investigate and apply low-cost integrative oncology strategies to support better treatment outcomes and minimise adverse events. Further research may lead to pre-treatment assessment of both tumour and patient-associated biomarkers and personalised multimodal prehabilitation care plans, as well as on-treatment support with targeted nutrition, physical activity, and supplementation regimes, including both systemic inflammation and gut microbiome modulating strategies. Given the emerging understanding of chronic stress impact on ICI treatment outcomes, mind-body approaches require further investigation.

Nicoletti M. The Antioxidant Activity of Mistletoes ( Viscum album and Other Species). PLANTS (BASEL, SWITZERLAND) 2023; 12:2707. [PMID: 37514321 PMCID: PMC10384781 DOI: 10.3390/plants12142707] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Revised: 07/17/2023] [Accepted: 07/17/2023] [Indexed: 07/30/2023]
Abstract
In addition to the European mistletoe, Viscum album, which is the most known and utilized one, there are several species commonly known as mistletoe. They are spread in various regions of the planet and are all characterized by hemiparasitism and epiphytic behaviour. The published studies evidence other similarities, including the sharing of important biological properties, with the common presence of antioxidant effects. However, whereas the European mistletoe is largely utilized in medical treatments, although with controversial aspects, the scientific knowledge and medical uses of other mistletoes are still insufficient. This review focuses on the controversial medical story of European mistletoe regarding its antioxidant activity and the potentiality of the other species named mistletoe pertaining to botanical families and genera different from Viscum.

Abstract
The therapeutic story of European mistletoe (Viscum album L.) presents a seesawing profile. In ancient times, this hemiparasitic plant was considered a panacea and even to be endowed with exceptional beneficial properties. In more recent times, despite its multiple uses in traditional medicines, some parts of the plant, in particular the berries, were considered poisonous and dangerous, including concerns of cytotoxicity, which spread serious suspicion on its medicinal utility. However, since the last century, medical interest in mistletoe has come back in force due to its utilization in clinical cancer treatments, based on its selective action on tumor cells. In Central Europe, the hydro-alcoholic extracts of European mistletoe register a relevant and continuous utilization in anthroposophic medicine, which is a holistic system that includes the utilization of phytomedicinal substances. In Switzerland and Germany, most physicians and patients use these products as complementary therapy in oncological treatments. However, despite its increasing use in this field, the results of mistletoe's use are not always convincing, and other aspects have appeared. Nowadays, products that contain mistletoe are utilized in several fields, including diet, phytotherapy, veterinary medicine and homeopathy, but in particular in cancer therapies as coadjuvant factors, in consideration of several positive effects including effects in the improvement of quality-of-life conditions and reinforcement of the immune system. In this review, based on the understanding of the association between cancer and inflammation, we propose a relationship between these recent uses of mistletoe, based on its antioxidant properties, which are supported by phytochemical and pharmacological data. The unicity of mistletoe metabolism, which is a direct consequence of its hemiparasitism, is utilized as a key interpretation element to explain its biological properties and steer its consequent therapeutic uses.

Abstract
BACKGROUND Viscum album L. (VA) preparations possess immunomodulatory properties and are used in complementary medicine to support cancer therapy. It is unclear if there is an impact of VA on the expression of immune checkpoint proteins on the surface of cancer cells. This study was designed to investigate the role of commercially available VA preparations on checkpoint programmed death ligand 1, 2 (PD-L1, PD-L2) and on major histocompatibility complex class I (MHC-I). METHODS Four human cancer cell lines (prostate, colon, lung, and breast) were assayed for their PD-L1, PD-L2, and MHC-I level after stimulation with interferon-gamma (IFN-γ). The toxicity of mistletoe preparations for the cells was analysed. Afterwards, the effect of mistletoe preparations on the PD ligands and MHC-I was investigated. RESULTS Surface protein analysis demonstrated that all tested tumour cell lines increased the PD-L1, PD-L2, and MHC-I-expression, but to different extents, after IFN-γ stimulation. Treatment with VA extracts did not influence the viability of the cells. The expression of PD ligands and MHC-I was not affected by incubation with the VA preparations. CONCLUSION Our investigation concludes that VA treatment does not interfere with the expression of PD ligands or MHC-I among selected cancer cells. Hintergrund Viscum album L. (VA)-Präparate besitzen immunmodulatorische Eigenschaften und werden in der Komplementärmedizin zur Unterstützung in der Krebstherapie eingesetzt. Es ist jedoch unklar, ob VA einen Einfluss auf die Expression von Immuncheckpoint-Proteinen auf Krebszellen hat. In der vorliegenden Arbeit wurde ein Einfluss von handelsüblichen VA-Präparaten auf die Checkpoint-Proteine programmed death ligand 1, 2 (PD-L1, PD-L2) und major histocompatibility complex class I (MHC-I) untersucht. Methoden Vier humane Krebszelllinien der Prostata, des Dickdarms, der Lunge und Brust wurden nach Stimulation mit Interferon-gamma (IFN-γ) auf ihre PD-L1, PD-L2 und MHC-I Konzentration untersucht. Zunächst wurde die Toxizität von Mistelpräparaten auf die Tumorzellen analysiert. Anschließend erfolgte eine Charakterisierung der Wirkung von Mistelpräparaten auf die PD-Liganden und MHC-I. Ergebnisse Die Oberflächenproteinanalysen zeigten, dass alle getesteten Tumorzelllinien nach einer IFN-γ-Stimulation die PD-L1, PD-L2 und MHC-I Expression in unterschiedlichem Ausmaß erhöhten. Die Behandlung mit verschiedenen VA-Extrakten hatte keinen Einfluss auf die Viabilität der Zellen, sowie auf die Expression der PD-Liganden und MHC-I. Schlussfolgerung Unsere Untersuchung kommt zu dem Schluss, dass eine VA-Behandlung die Expression von PD-Liganden oder MHC-I in den untersuchten Krebszellen nicht beeinflusst.

Abstract
BACKGROUND Newer personalized medicines including targeted therapies such as PARP inhibitors and CDK 4/6 inhibitors have been shown to improve the survival of breast and gynaecological cancer patients. However, efficacy outcomes may be ham5pered by treatment discontinuation due to targeted therapy-related adverse drug reactions or resistance. Studies have suggested that add-on mistletoe (Viscum album L., VA) improves the quality of life and ameliorates the cytotoxic side effects of standard oncological therapy in cancer patients. The primary objective of this real-world data study was to determine the safety profile of targeted therapy in combination with add-on Helixor® VA therapy compared to targeted therapy alone in breast and gynecological cancer patients. METHODS The present study is a real-world data observational cohort study utilizing demographic and treatment data from the accredited national Network Oncology (NO) registry. The study has received ethics approval. The safety profile of targeted therapies with or without Helixor® VA therapy and safety-associated variables were evaluated by univariate and adjusted multivariable regression analyses. RESULTS All stages of breast and gynecological cancer patients (n = 242) were on average 54.5 ± 14.2 years old. One hundred and sixty patients (66.1%) were in the control (CTRL, targeted therapy) and 82 patients (33.9%) were in the combinational (COMB, targeted plus Helixor® VA therapy) group. The addition of Helixor® VA did not hamper the safety profile (χ2 = 0.107, p-value = 0.99) of targeted therapy. Furthermore, no adverse events and a trend towards an improved targeted therapy adherence were observed in the COMB group. CONCLUSIONS The present study is the first of its kind showing the applicability of Helixor® VA in combination with targeted therapies. The results indicate that add-on Helixor® VA does not negatively alter the safety profile of targeted therapies in breast and gynaecological cancer patients.

Abstract
BACKGROUND Complementary and alternative medicine (CAM) is used by about 40-90% of all patients with cancer. CAM also includes phytotherapy, which is considered to be a biologically based therapy. Depending on the survey, the users of phytotherapy account for up to 80%. The intention of the users is to fight cancer or to alleviate its symptoms. OBJECTIVES Frequently used phytotherapeutics with their level of evidence and possible pitfalls are presented in a narrative review. Special attention is given to the uro-oncological context. MATERIALS AND METHODS Popular phytotherapeutics (mistletoe, pomegranate, aloe vera, sage, ginger, ginseng) as well as three uronephrological plants (juniper, horsetail, bearberry) are classified and evaluated according to existing guidelines and by using a selective literature search. RESULTS A total of nine plants were considered. Currently, there is no sufficient evidence for the use of pomegranate or mistletoe for tumor therapy. Guideline recommendations for or against symptom-oriented use exist for ginger (nausea; may be used), ginseng (fatigue; may be used), aloe vera (radiation dermatitis, should not be recommend), and bearberry (recurrent cystitis, may be used). A small number of studies on other symptoms and medicinal plants could be found (e.g., ginger - xerostomia, aloe vera - constipation, sage - oral mucositis or sweating). CONCLUSIONS An integration of phytotherapeutic drugs into uro-oncological treatments concept can be considered. The benefits and risks of complementary herbal medicines (e.g., potential interactions with tumor therapy) must always be carefully weighed.

Abstract
Abstract
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.

Specificity of viscumin revised. As probed with a printed glycan array. Biochimie 2022; 202:94-102.

Abstract
Viscumin, a lectin used in anti-cancer therapy, was originally considered as βGal recognizing protein; later, an ability to bind 6'-sialyl N-acetyllactosamine (6'SLN) terminated gangliosides was found. Here we probed viscumin with a printed glycan array (PGA) containing a large number of mammalian sulfated glycans, and found a strong binding to glycans with 6-O-SuGal moiety as lactose, N-acetyllactosamine (LN), di-N-acetyllactosamine (LacdiNAc), and even 6-O-SuGalNAcα (but not SiaTn). Also, the ability to bind some of αGal terminated glycans, including Galα1-3Galβ1-4GlcNAc, was observed. Unexpectedly, only weak interaction was detected with parent neutral β-galactosides including LN-LN-LN and branched (LN)2LN oligolactosamines; in the light of these data, one should not confidently classify viscumin as a β-galactoside-binding lectin. Carrying out PGA in the presence of neutral or sulfated/sialylated glycan, together with sequential elution from lactose-sepharose and consideration of the protein structure, lead to the conclusion that two glycan-binding sites of viscumin have different specificities, one of which prefers charged sulfated and sialylated moieties.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 103:154247. [PMID: 35716539 DOI: 10.1016/j.phymed.2022.154247] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Revised: 05/14/2022] [Accepted: 06/05/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND The concurrent use of conventional drugs and herbal medicines is becoming popular among patients with cancer. However, the potential risk of herb-drug interactions (HDI) remains under-addressed in the literature. Previous reviews have mainly focused on the prevalence of interactions, with less attention paid to the methods used by pharmacoepidemiological studies on evaluating HDI. This scoping review aims to summarize the existing pharmacoepidemiological studies that evaluate HDI using real-world data and to identify gaps to be addressed in future research. METHODS A comprehensive search was performed in nine English- and Chinese-language databases from their inception to May 2021. Gray literature and manual searches were conducted to identify additional studies. The recommended components of the pharmacoepidemiological studies and key findings related to HDI were summarized. The proportion (%) of patients with cancer at risk of HDI was estimated by combining data from eligible studies. RESULTS Twenty-eight studies were included in the review. More than half of these studies were cross-sectional studies (n = 18, 64.3%), followed by retrospective cohort studies (n = 5, 17.9%) and prospective cohort studies (n = 2, 7.1%). The three cancer drugs most commonly studied for their interaction potential with herbs were tamoxifen (n = 11, 39.3%), cyclophosphamide (n = 6, 21.4%), and paclitaxel (n = 6, 21.4%). Most cross-sectional studies identified potential HDI using tertiary databases and primary literature searches. Conversely, prospective and retrospective studies mainly investigated actual clinical outcomes, such as adverse events and secondary cancer occurrences. Most interaction outcomes identified using real-world data did not lead to negative clinical consequences. Collectively, 45.4% of herbal medicine users of the included studies were found to be at risk of HDI. We infer from this review that the common limitations of these studies were limited sample size, lack of data on herbal medicine use and details of HDI, and lack of evidence of HDI. Based on the study limitations, several recommendations to enrich the data sources and optimize the study designs were proposed. CONCLUSIONS There is a high demand for pharmacoepidemiological research on HDI, considering the increasing popularity of herbal medicine among patients with cancer. It is anticipated that emerging real-world data in this field can guide the development of safe and effective approaches to integrative oncology.

Abstract
Herbal food supplements are commonly used and can be an important part of patient self-care. Like all other bio-active and therapeutic products, they have a benefit/risk balance. These products are not without adverse effects and potentially interact with other therapies. Educating patients and providing information for health professionals about the risk of herb-drug interactions is key. One of the purposes of the biomedical literature is to inform prescribers. Scientific literature accessible on databases such as PubMed is dense and careful reading is time consuming. We propose a reading aid tool named "HDI highlighter" to help readers to find key information in clinical studies and case reports describing herb-drug interactions. It uses natural language processing algorithms (artificial intelligence) with a pharmaceutical focus. Semantic relation extraction for herb-drug interactions from the biomedical literature are overexpressed using keywords. We have tested it to review 120 published articles over the last 10 years. In these articles, we have shown that case reports often involved long-term or semi-long-term treatments such as cancer or human immunodeficiency virus therapies, antiepileptic drugs, or central nervous system drugs. Similarly, these classes of drugs are more extensively targeted by clinical studies. Herb-drug interactions described in case reports are identified in medicinal, recreational, and alimentary uses. They also usually lack a rigorous description of the herb(s) involved. Typically, clinical studies provide a complete description of protocols and dosages, with a few exceptions explained by patients' needs. Clinical studies on herbs are nevertheless conducted on a limited number of patients. All these limitations make the interpretation of herb-drug interactions complicated, but the HDI highlighter provides a quick overview of the herb-drug interaction literature.

Abstract
This review examines three bodies of literature related to herb-drug interactions: case reports, clinical studies, evaluations found in six drug interaction checking resources. The aim of the study is to examine the congruity of resources and to assess the degree to which case reports signal for further study. A qualitative review of case reports seeks to determine needs and perspectives of case report authors. Methods: Systematic search of Medline identified clinical studies and case reports of interacting herb-drug combinations. Interacting herb-drug pairs were searched in six drug interaction resources. Case reports were analyzed qualitatively for completeness and to identify underlying themes. Results: Ninety-nine case-report documents detailed 107 cases. Sixty-five clinical studies evaluated 93 mechanisms of interaction relevant to herbs reported in case studies, involving 30 different herbal products; 52.7% of these investigations offered evidence supporting reported reactions. Cohen's kappa found no agreement between any interaction checker and case report corpus. Case reports often lacked full information. Need for further information, attitudes about herbs and herb use, and strategies to reduce risk from interaction were three primary themes in the case report corpus. Conclusions: Reliable herb-drug information is needed, including open and respectful discussion with patients.

Abstract
Complementary and alternative medicine (CAM) is widespread in oncology patients with a user rate of approximately 40-50%. An accompanying supportive effect can arise through improved adherence, especially in long-term (e.g. endocrine) therapies through active patient involvement. When assessing the evidence on frequently requested methods, there is no high-quality evidence that homeopathy or anthroposophy leads to an improved prognosis. Mistletoe therapy can be considered to improve the quality of life, although the data quality is weak. In prostate cancer, pomegranate has an influence on the prostate-specific antigen. It is currently unclear whether this will also result in an improved prognosis. In contrast the evidence on selenium and vitamin D speaks in favor of integration into the aftercare concept. Supplementation is recommended after the serum level has been determined.

Abstract
Mistletoe (Viscum album L.) continues to be the medical herb prescribed most frequently for cancer patients in German-speaking countries. Demand for this therapy often comes from patients themselves and requires careful consideration by the attending physician during consultation.In German-speaking countries, mistletoe extracts are available as approved drugs (based on monographs of the commissions C and E of the German Federal Institute for Drugs and Medical Devices). In Switzerland, treatment costs are generally covered by statutory health insurance. In Germany, coverage is limited to palliative care. In adjuvant cases, treating physicians can request coverage by the health insurance if patients suffer from side effects due to the antitumoral treatment.The spectrum of Viscum album extract includes mistletoe lectin I; II, and III, viscotoxins, flavonoids, amino acids, polysaccharides, and membrane lipids. Preclinical studies have demonstrated cytotoxic, apoptosis-inducing, and immunomodulatory effects.Many clinical studies indicate a supportive efficacy of mistletoe extracts in tumor patients, even though methodological quality is discussed controversially in many cases. Clinical data regarding effects on survival of patients is inconsistent; effects concerning quality of life as well as the tolerability of antitumoral treatments are evaluated more positively.In view of the high demand on the patient side and increasing scientific evidence, the general conditions for prescriptions should continue as well as the ongoing scientific evaluation.

Abstract
Conventional methods in treating non–small cell lung cancer contain surgery,
chemotherapy, radiotherapy, and targeted therapy, which have various defects.
Recently, with the deeper research on tumor immunity, immunotherapy has made the
breakthrough in the treatment of cancers. Especially developments of programmed
cell death-1/programmed cell death ligand-1 (PD-1/PD-L1) inhibitors bring the
therapy into a new stage. This review mainly focuses on introducing existing
monoclonal antibodies containing nivolumab, pembrolizumab, atezolizumab,
avelumab, and durvalumab, along with 3 ordinary biomarkers such as PD-L1
expression, tumor mutation burden, and microsatellite instability. By
understanding the resistance mechanism of anti-PD-1/L1 blockade, research is
further improving the survival benefit and expanding the benefit population. So,
PD-1/PD-L1 inhibitors begin to be combined with various therapeutic strategies
clinically. Discussion and comparison of their effectiveness and safety are also
comprehensively reviewed. Meanwhile, we explore the potential, the impact, and
mechanisms of combining traditional Chinese medicine with immunotherapy.

Abstract
OBJECTIVE The aim of this study was to assess the potential risks of interactions between biologically based complementary and alternative medication (BB-CAM) and conventional drugs during systemic therapy in breast and gynecological cancer patients by analyzing the actual CAM-drug combinations from individual patients' records. METHODS From September 2014 to December 2014 and from February 2017 to May 2017, all patients (n = 717) undergoing systemic therapy at the Gynecologic Oncology Day Care Unit in the Gynecology and Obstetrics Department of the Technical University of Munich, Germany, were asked to participate in a questionnaire about all their medications. To assess the potential risk of CAM-drug interactions (CDIs), we initially utilized the Lexicomp drug interaction database. This assessment was then expanded with a systematic search of other digital databases, such as the National Center for Complementary and Integrative Health, Memorial Sloan Kettering Cancer Center, PubMed, and MEDLINE as well as the Cochrane Library. RESULTS Among 448 respondents, 74.1% reported using BB-CAM simultaneously with their systemic therapy. The assessment showed 1 patient with a potentially clinically relevant CDI, where the interaction was based on a self-medicated combination of Echinacea and cyclophosphamide. Furthermore, 81 patients (18.1%) were thought to have interactions because of a combination of BB-CAMs and cytochrome P450 3A4-metabolized anticancer drugs. CONCLUSIONS Our data demonstrated high overall use of BB-CAMs by cancer patients undergoing systemic therapy. The analyses showed only 1 clinically relevant CDI.

Abstract
Background Whole medicine and health systems like traditional and complementary medicine systems (T&CM) are part of healthcare around the world. One key feature of T&CM is its focus on patient-centered and multimodal care and the integration of intercultural perspectives in a wide range of settings. It may contribute to good health and well being for people as part of the Sustainable Development Goals of the United Nations. The authentic, rigorous, and fair evaluation of such a medical system, with its inherent complexity and individualization, imposes methodological challenges. Hence, we propose a broad research strategy to test and characterize its possible contribution to health. Methods To develop a research strategy for a specific T&CM system, Anthroposophic Medicine (AM), applying multimodal integrative healthcare based on a four-level concept of man, we used a three-phase consensus process with experts and key stakeholders, consisting of (1) premeeting methodological literature and AM research review and interviews to supplement or revise items of the research strategy and tailor them to AM research, (2) face-to-face consensus meetings further developing and tailoring the strategy, and (3) postmeeting feedback and review, followed by finalization. Results Currently, AM covers many fields of medical specialties in varied levels of healthcare settings, such as outpatient and inpatient; primary, secondary, and tertiary care; and health education and pedagogy. It is by definition integrated with conventional medicine in the public healthcare system. It applies specific medicines, nursing techniques, arts therapies, eurythmy therapy, rhythmical massage, counseling, and psychotherapy, and it is provided by medical doctors, nurses, therapists, midwives, and nutritionists. A research strategy authentic to this level of complexity should comprise items with a focus on (I) efficacy and effectiveness, divided into (a) evaluation of the multimodal and multidisciplinary medical system as a whole, or of complex multimodal therapy concept, (b) a reasonable amount of methodologically rigorous, confirmatory randomized controlled trials on exemplary pharmacological and nonpharmacological therapies and indications, (c) a wide range of interventions and patient-centered care strategies with less extensive formats like well-conducted small trails, observational studies, and high-quality case reports and series, or subgroup analyses from whole-system studies, or health service research; (II) safety; (III) economics; (IV) evidence synthesis; (V) methodologic issues; (VI) biomedical, physiological, pharmacological, pharmaceutical, psychological, anthropological, and nosological issues as well as innovation and development; (VI) patient perspective and involvement, public needs, and ethics; (VII) educational matters and professionalism; and (IX) disease prevention, health promotion, and public health. Conclusion The research strategy extends to and complements the prevailing hierarchical system by introducing a broad “evidence house” approach to evaluation, something many health technology assessment boards today support. It may provide transparent and comprehensive insight into potential benefits or risks of AM. It can serve as a framework for an evidence-informed approach to AM for a variety of stakeholders and collaborating networks with the aim of improving global health.

Abstract
In early tumor development, cancer cells develop a plethora of strategies to escape surveillance from the adaptive and innate immune system. Cancer immunotherapies, in particular immune checkpoint inhibitors, are becoming a highly promising cancer therapeutic approach that has remarkable increased progress in combating various cancer types. Unfortunately, their mechanisms of action induce some complications, such as inflammatory reactions and immune-related adverse events. In the management of side effects during anticancer therapy, complementary and integrative therapy approaches are becoming of growing interest. Particularly, mistletoe, Viscum album L. (VA), has a long traditional history of about 100 years as an add-on therapy of cancer treatment in German-speaking countries. Besides antitumoral and quality of life-promoting activities, VA applications reduce side effects of modern conventional anticancer therapies and exert immunomodulatory characteristics. As these properties may provide a good basis for a combination with modern oncological therapies, the biological activities of VA applications and mechanisms involved have to be understood. In this review, the impact of VA compounds on different cellular pathways and immunological reactions in the fight against cancerous cells is discussed.

Abstract
INTRODUCTION Metastatic renal cell carcinoma has a poor prognosis. Treatment approaches with immunotherapy show promising results in subpopulations. Viscum album extracts - used as an adjunct to cancer treatment - have cytotoxic, apoptogenic, and immune-stimulating properties and show synergistic effects with chemotherapy agents. CASE REPORT A 51-year-old man was diagnosed with metastatic renal cell carcinoma of clear cell histology which was classified as pT3a, N1, M1, G3. Nephrectomy was performed, and the patient received chemoimmunotherapy (interferon-α2a, interleukin-2, fluorouracil, isotretinoin). Additionally, he received V. album extracts as intravenous infusions and subcutaneous injections. One year after surgery, the patient was in complete remission, which is ongoing 18 years after the initial diagnosis. DISCUSSION This case shows an extraordinarily long survival of a metastasized renal cell carcinoma patient under chemoimmunotherapy and fever-inducing V. album extracts. This combined treatment might have synergistically contributed to tumor remission and control. With regard to clinical relevance, further investigations are needed.

Abstract
BACKGROUND Viscum album L (VA, mistletoe) extracts are commonly used in integrative oncology. Here the clinical safety profile of additional VA-treatments to standard care in cancer patients with preexisting autoimmune diseases was analyzed. METHODS In this observational cohort study medical data and recorded adverse events (AEs) of treated patients were retrieved from the Network Oncology registry and a safety analysis was performed. RESULTS A total of 106 patients (median age 63 years) treated with add-on VA-extracts were analyzed. Most frequent autoimmune diseases were Hashimoto's thyroiditis (27%), psoriasis (19%), and ulcerative colitis (15%). Seventeen patients (16%) experienced VA-related AEs, but neither long-term side effects nor VA-therapy discontinuations were recorded. In a subgroup of 30 patients receiving long-term VA-therapy no exacerbations or flares of underlying autoimmune diseases were recorded. Additionally, a significant halving of overall AE-rates was observed during VA-treatment periods (p= 0.019). CONCLUSIONS Our findings suggest that add-on VA-therapy in cancer patients with preexisting autoimmune diseases as Hashimoto's thyroiditis, psoriasis, ulcerative colitis, Grave's disease, and some rheumatic diseases is safe. No higher rates of VA-associated AEs were observed and the overall AE-rates were significantly lowered in VA-therapy periods. However, results should be interpreted with caution in light of the study's observational character.

Abstract
BACKGROUND Intrahepatic sarcomatoid chonalgiocarcinoma (s-CCC) is an extremely rare disease, accounting for less than 1% of hepatobiliary system malignancies, and its pathophysiology is not well known. On the hypothesis that its clinical, serologic, or radiologic diagnosis are not fully understood and its prognosis is poor, we investigated the distinguishing features of s-CCC compared with those of intrahepatic bile duct adenocarcinoma [cholangiocellular carcinoma (CCC)] in patients from a single center.
AIM To analyze the clinical, serologic, imaging, and histopathologic characteristics of intrahepatic s-CCC patients diagnosed in a single center.
METHODS The clinical, serologic, imaging, and histopathologic features of 227 patients diagnosed with intrahepatic cholangiocarcinoma (IHCC) in a single medical center during the last 17 years were analyzed. The characteristics of 11 patients with s-CCC were compared with those of 216 patients with CCC.
RESULTS The number of patients with s-CCC who presented fever and abdominal pain and past history of chronic viral hepatitis or liver cirrhosis (LC) was higher than that of patients with CCC. In imaging studies, patients with s-CCC showed relatively aggressive features. However, no clear distinction was observed between s-CCC and CCC based on other clinical, serologic or radiologic examination results. An accurate diagnosis could be made only via a histopathologic examination through immunohistochemical staining. The clinical course of s-CCC was generally aggressive, and patients had a relatively poor prognosis.
CONCLUSION In patients with s-CCC, early diagnosis through biopsy and aggressive treatment, including surgical resection, are important.

Abstract
Background: Despite improvement of tumor response rates, targeted therapy may induce toxicities in cancer patients. Recent studies indicate amelioration of adverse events (AEs) by add-on mistletoe (Viscum album L., VA) in standard oncological treatment. The primary objective of this multicenter observational study was to determine the safety profile of targeted and add-on VA therapy compared to targeted therapy alone. Methods: Demographic and medical data were retrieved from the Network Oncology registry. Allocation to either control (targeted therapy) or combinational group (targeted/add-on VA) was performed. Safety-associated variables were evaluated by adjusted multivariable analyses. Results: The median age of the study population (n = 310) at first diagnosis was 59 years; 67.4% were female. In total, 126 patients (40.6%) were in the control and 184 patients (59.4%) in the combination group. Significant differences were observed between both groups with respect to overall AE frequency (χ2 = 4.1, p = 0.04) and to discontinuation of standard oncological treatment (χ2 = 4.8, p = 0.03) with lower rates in the combinational group (20.1%, 35% respectively) compared to control (30.2%, 60.5%, respectively). Addition of VA to targeted therapy significantly reduced the probability of oncological treatment discontinuation by 70% (Odds ratio (OR) 0.30, p = 0.02). Conclusions: Our results indicate a highly significant reduction of AE-induced treatment discontinuation in all-stage cancer patients when treated with VA in addition to targeted therapy.
