Systematic analysis of mistletoe prescriptions in clinical studies. J Cancer Res Clin Oncol 2022:10.1007/s00432-022-04511-2. [PMID: 36481925 PMCID: PMC10356894 DOI: 10.1007/s00432-022-04511-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Accepted: 12/01/2022] [Indexed: 12/13/2022]
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.

Abstract
Retroperitoneal sarcomas are rare. Dedifferentiated liposarcomas (DDLs) are high-grade tumors with a high propensity for local recurrence and metastasis and are associated with reduced survival. Radical resection remains the standard treatment of sarcomas. Meanwhile, Viscum album L. extract (VAE) is used in cancer patients owing to its cytostatic and immunomodulating effects and to its ability to improve patients’ quality of life.

Abstract
RATIONALE Thymic neuroendocrine tumor (TNET) is very rare and characterized by a tendency to invade adjacent structures, frequent metastasis, resistance to therapy, and a poor prognosis. Viscum album extracts (VAE) have shown immunological, apoptogenic, and cytotoxic properties. PATIENT CONCERNS A 54-year-old Peruvian man was suffering from constant fatigue, cough, dyspnea, and fever for a couple of months. DIAGNOSES He was diagnosed with TNET (12.8 cm × 10 cm × 7 cm) stage IIIa, G1. Due to the size and extensive invasiveness (vena cava superior, also obstructing 85% of its lumen, pericardium, and pleura), the TNET was inoperable. INTERVENTIONS We report the case of this patient who declined chemotherapy and was treated instead with sole subcutaneous VAE 3 times per week for 85 months. No other tumor-specific intervention was applied. OUTCOMES Quality of life (QoL) improved substantially. The patient returned to work, and the tumor remained stable for 71 months. Thereafter, the tumor progressed, and the patient died 90 months after initial diagnosis. Besides self-limited local skin reactions around the application site, no side effects occurred. LESSONS This is an exceptionally good course of disease of an inoperable, large, obstructing, and invasive TNET with a reduced baseline condition (Karnofsky index: 50-60) due to pronounced symptoms. Given the considerable reduction of symptoms and improved QoL following the onset of VAE therapy and other reports describing long disease stability and improvement of the QoL using VAE in different cancer types, we presume that the VAE treatment was supportive in this case. As TNETs are rare and few trials are available, future treatments of TNETs using VAE should be carefully documented and published to help determine whether further investigation of the use of VAE in TNET treatment is worthwhile.

Abstract
INTRODUCTION Epithelial ovarian cancer (EOC) has a poor prognosis in advanced stages. High-dose chemotherapy (HDC) was pursued in the 1990s but was not found to improve survival of patients with EOC in larger studies. Many patients with cancer use Viscum album extracts (VAE). Also called European mistletoe, Viscum album can lead to improved quality of life and reduced chemotherapy side effects and may have synergistic cytotoxic and proliferation-inhibiting effects when used together with chemotherapy. CASE PRESENTATION A high-grade serous epithelial ovarian carcinoma with peritoneal, adrenal, and hepatic metastases (FIGO Stage IV) was diagnosed in a 50-year-old premenopausal woman. Tumor and metastases were surgically removed in cytoreductive surgery, and the patient received adjuvant chemotherapy, without experiencing side effects from treatment. After a second-look surgery revealed lymph node metastases, HDC and autologous hematopoietic stem cell transplantation were performed. Additionally, the patient opted for treatment with VAE, which she continuously received. The patient remained tumor-free in follow-up examinations and has enjoyed good health for 20 years after initial diagnosis. DISCUSSION Treatment with VAE in this case might have contributed to the reduction of side effects from HDC and may have acted synergistically with HDC in tumor control. Cases of VAE in EOC should be carefully documented and reported to further illustrate the influence of VAE on this cancer presentation.

Abstract
Background Skull metastases are rare, they can eventually cause pain, and can invade the brain. Viscum album extracts (VAEs) are used as an adjuvant treatment in cancer. Methods and Results A 68‐year‐old patient with rectal cancer presented with lung metastases, and metastases to multiple bone sites, the chest wall, and the liver were later identified. Histological examination of one of the bone lesions revealed an additional thyroid carcinoma. An osteolytic parietal bone lesion progressed to a painful metastasis of the skull despite radiotherapy and chemotherapy. The VAEs were applied weekly into the metastasis, followed by pain relief and softening of the lesion. The lesion partially regressed (>50%) after 8 months of continued VAE treatment and remained stable for 2 years. Conclusion This case shows a durable clinical remission of a skull metastasis under VAE. Further investigations of intratumoral VAE treatment seem worthwhile—especially in symptomatic skull metastases not responding to radiotherapy or systemic therapies.

Abstract
INTRODUCTION Metastatic malignant cutaneous melanoma (MCM)-a highly immunogenic cancer-typically has a poor prognosis. Viscum album extracts (VAEs) have strong immune-stimulating, apoptogenic, and cytotoxic effects. CASE PRESENTATION A 66-year-old MCM patient with newly diagnosed lymph node metastases opted for sole VAE treatment. VAEs were initially applied subcutaneously, and then later in exceptionally high, fever-inducing doses, both intravenously and intralesionally. The metastases shrunk over the following months, and after 2 years, all lesions had completely remitted (regional and hilar lymph nodes). The patient has been tumor free for 3.5 years at the time of publication (and for 5 years since initiation of intensified VAE treatment). Besides fever and flu-like symptoms, no side effects occurred. DISCUSSION We presume that VAE triggered an increased release of tumor-associated antigens, enhanced immunologic recognition, and increased immune response against the tumor tissue and induced tumor remission.

Abstract
Background Cancer patients widely seek integrative oncology which embraces a wide variety of treatments and system approaches. Objective To investigate the concepts, therapeutic goals, procedures, and working conditions of integrative oncology doctors in the field of anthroposophic medicine. Methods This qualitative study was based on in-depth interviews with 35 highly experienced doctors working in hospitals and office-based practices in Germany and other countries. Structured qualitative content analysis was applied to examine the data. Results The doctors integrated conventional and holistic cancer concepts. Their treatments aimed at both tumor and symptom control and at strengthening the patient on different levels: living with the disease, overcoming the disease, enabling emotional and cognitive development, and addressing spiritual or transcendental issues according to the patient's wishes and initiatives. Therapeutic procedures were conventional anticancer and symptom-relieving treatments, herbal and mineral remedies, mistletoe therapy, art therapies, massages and other external applications, nutrition and lifestyle advice, psychological support, and multiple forms of empowerment. The approach emphasised good patient-doctor relationships and sufficient time for patient encounters and decision-making. Individualization appeared in several dimensions and was interwoven with standards and mindlines. The doctors often worked in teams and cooperated with other cancer care-related specialists. Conclusion Integrative cancer care pursues an individualized and patient-centered approach, encompassing conventional and multimodal complementary interventions, and addressing, along with physical and functional needs, the emotional and spiritual needs of patients. This seems to be important for tumor and symptom control, and addresses major challenges and important goals of modern cancer care.

Abstract
Background. Mistletoe therapy (MT) is widely used in patient-centered integrative cancer care. The objective of this study was to explore the concepts, procedures, and observations of expert doctors, with a focus on intravenous MT. Method. A qualitative interview study was conducted with 35 highly experienced doctors specialized in integrative and anthroposophic medicine. Structured qualitative content analysis was applied. For triangulation, the results were compared with external evidence that was systematically collected, reviewed, and presented. Results. Doctors perform individualized patient assessments that lead to multimodal treatment approaches. The underlying goal is to help patients to live with and overcome disease. Mistletoe infusions are a means of accomplishing this goal. They are applied to stabilize disease, achieve responsiveness, induce fever, improve quality of life, and improve the tolerability of conventional cancer treatments. The doctors reported long-term disease stability and improvements in patients' general condition, vitality, strength, thermal comfort, appetite, sleep, pain from bone metastases, dyspnea in pulmonary lymphangitis carcinomatosa, fatigue, and cachexia; chemotherapy was better tolerated. Also patients' emotional and mental condition was reported to have improved. Conclusion. Individualized integrative cancer treatment including MT aims to help cancer patients to live well with their disease. Further research should investigate the reported observations.
