Characteristics of cancer patients using homeopathy compared with those in conventional care: a cross-sectional study

Working with patients' treatment expectations - what we can learn from homeopathy

The usual homeopathic remedy, "globules," does not contain any pharmacologically active ingredient. However, many patients and practitioners report beneficial effects of homeopathic treatment on various health outcomes. Experimental and clinical research of the last two decades analyzing the underlying mechanisms of the placebo effect could explain this phenomenon, with patients' treatment expectations as the predominant mechanism. Treatment expectations can be optimized through various factors, such as prior information, communication, and treatment context. This narrative review analyses how homeopathy successfully utilizes these factors. Subsequently, it is discussed what evidence-based medicine could learn from homeopathic practice to optimize treatment expectations (e.g., using an empathic, patient-centered communication style, deliberately selecting objects in practice rooms, or using clear treatment rituals and salient contextual stimuli) and thereby treatment effectiveness. Homeopathic remedy does not work beyond the placebo effect but is recommended or prescribed as an active treatment by those who believe in it. Thus, practitioners need to understand the manner in which homeopathy (as an example of inert treatment) works and are advised to reintegrate its underlying effective placebo mechanisms into evidence-based medicine. This promises to increase treatment efficacy, tolerability, satisfaction, and compliance with evidence-based treatments, and addresses the desires patients are trying to satisfy in homeopathy in an ethical, fully informed way that is grounded in evidence-based medicine.

Homeopathy as Praxis: Integration of Homeopathy as Supportive Care into Daily Life in Early Breast Cancer Patients

INTRODUCTION

Homeopathy is one of most widely used non-conventional supportive care methods used by women with breast cancer. This article aims to describe the routines and practices related to homeopathy as supportive care used by women with non-metastatic breast cancer in France.

METHODS

This qualitative study used Grounded Theory. Participants were women with early breast cancer and healthcare professionals (General Practitioner homeopaths & oncologists). Inclusion depended on specific criteria and the aim of theoretical sampling until data saturation. Data were collected through individual semi-structured interviews and focus groups following evolving topic guides. Transcribed interviews underwent in-depth thematic analysis. Inclusion, interviewing, transcription and coding occurred iteratively. Data was reported according to COREQ guidelines.

RESULTS

The therapeutic agency of homeopathy was distributed to different actors and ritualized material activities highly involving the patient. The choice of remedy was mostly delegated by patients to General Practitioner homeopaths (GPH) during consultations. Individualization, that is to say adaptation to the patient, differed from other modes of access to homeopathy (self-medication and oncologists). Self-medication was mostly limited to known products in a limited time frame. However, we identified a supported self-medication using trusted homeopathic protocols. Following homeopathic prescriptions involves a high level of commitment on behalf of the patient and follows different rules for homeopathy intake. This knowledge was either acquired earlier for users or discovered along breast cancer treatment for non-users. Taking homeopathy involved small daily actions for intake of different products at different times of the day. New users used strategies to ease the integration of homeopathy into their daily life. The stance toward such rules differed among patients. Some followed rules to optimize their effects while others simplified the rules and took those rituals as part of homeopathy benefits.

CONCLUSION

Homeopathy as supportive care in breast cancer is distributed toward different actors and ritualized activities. Homeopathy is a supported practice where GPH played a role in the prescription. Health Literacy in homeopathy played a role to ease its integration into daily life and identify the potential benefits. The high involvement of patients in their homeopathic treatment is a form of treatment reappropriation and empowerment.

Utilisation of complementary medicine in cancer patients and survivors: Expected benefits and its association to psychosocial factors

INTRODUCTION

Previous research showed that various factors are associated with the use of complementary medicine (CM) in cancer patients. This study aimed to analyse the expected benefits of CM use in its association with medical, sociodemographic and psychosocial variables.

METHODS

In a cross-sectional survey, we assessed the use of CM, expected benefits of CM, depression and quality of life. An exploratory factor analysis (EFA) was performed. Multiple regression analysis was carried out with the factors derived from the EFA as dependent variables.

RESULTS

Based on 292 cancer CM user, EFA revealed two factors: a supportive effect (SPE) and an antitumoral effect (ATE). In the multiple regression analysis, reduced emotional functioning and the diagnosis of breast cancer are associated with the higher expectation of a supportive effect of CM (p < 0.001), explaining 7.1% of the variance. Emotional functioning, educational level and metastases are associated with higher expectation of an antitumoral effect of CM (p < 0.001) and explained 14.8% of the variance.

DISCUSSION

This study provides evidence that two overall domains (supportive effect and anti-tumoural effect) characterise the benefits of CM expected by cancer patients. Psychosocial and medical variables are associated with both domains, but explain only small proportion of the variance.

Prevalence of the Use of Herbal Medicines among Patients with Cancer: A Systematic Review and Meta-Analysis

Background

Although herbal medicines are used by patients with cancer in multiple oncology care settings, the magnitude of herbal medicine use in this context remains unclear. The purpose of this review was to establish the prevalence of herbal medicine use among patients with cancer, across various geographical settings and patient characteristics (age and gender categories).

Methods

Electronic databases that were searched for data published, from January 2000 to January 2020, were Medline (PubMed), Google Scholar, Embase, and African Index Medicus. Eligible studies reporting prevalence estimates of herbal medicine use amongst cancer patients were pooled using random-effects meta-analyses. Studies were grouped by World Bank region and income groups. Subgroup and meta-regression analyses were performed to explore source of heterogeneity.

Results

In total, 155 studies with data for 809,065 participants (53.95% female) met the inclusion criteria. Overall, the pooled prevalence of the use of herbal medicine among patients with cancer was 22% (95% confidence interval (CI): 18%–25%), with the highest prevalence estimates for Africa (40%, 95% CI: 23%–58%) and Asia (28%, 95% CI: 21%–35%). The pooled prevalence estimate was higher across low- and middle-income countries (32%, 95% CI: 23%–42%) and lower across high-income countries (17%, 95% CI: 14%–21%). Higher pooled prevalence estimates were found for adult patients with cancer (22%, 95% CI: 19%–26%) compared with children with cancer (18%, 95% CI: 11%–27%) and for female patients (27%, 95% CI: 19%–35%) compared with males (17%, 95% CI: 1%–47%).

Conclusion

Herbal medicine is used by a large percentage of patients with cancer use. The findings of this review highlight the need for herbal medicine to be integrated in cancer care.

Motivations of patients seeking supportive care for cancer from physicians prescribing homeopathic or conventional medicines: results of an observational cross-sectional study

BACKGROUND & AIMS

The motivations of patients who consult a homeopathic (GP-Ho) or conventional (GP-CM) general practitioner for supportive care during cancer treatment have not been widely studied. We investigated the reasons why cancer patients consult a GP-Ho versus a GP-CM for supportive care and the GPs' motivations for their prescriptions.

METHODS

This observational survey was carried out in France between October 2008 and October 2011. GPs across France were randomly selected and asked to recruit four cancer patients each. At inclusion, the sociodemographic and clinical (including psychological) characteristics and medical history of the patients were recorded by the GPs and the patients noted their quality of life (QoL) and anxiety/depression using the Quality of Life Questionnaire-C30 (QLQ-C30) and Hospital Anxiety and Depression Scale (HADS) self-questionnaires. The main motivations of the patients regarding the type of GP consultation and the main reasons for the GPs' prescriptions were recorded.

RESULTS

Six hundred and forty four patients were included in the analysis: 399 consulted a GP-CM (n = 112) and 245 a GP-Ho (n = 73). Patients consulting a GP-Ho were more often female [OR = 1.93; 95%CI: 1.11-3.35; p = 0.02], employed in a professional capacity [OR = 6.57; 95%CI: 1.96-21.99; p = 0.002], have a shorter time since cancer diagnosis [OR = 2.19; 95%CI: 1.24-3.87; p = 0.007], have received targeted anticancer therapy [OR = 3.70; 95%CI: 1.67-8.18; p = 0.001] and have a high QLQ-C30 score for constipation [OR = 1.01; 95%CI: 1.00-1.02; p = 0.001]. Patients mainly consulted a GP-Ho to receive overall care (73.5% vs. 64.9%; p = 0.024) and medicines to prevent anticancer treatment-related side-effects (63.7% vs. 41.4%; p < 0.0001). In contrast, patients consulted a GP-CM to receive psychological care (50.1% vs. 40.8%; p = 0.021) and more information regarding the oncologists' strategic decisions (p < 0.0001). There was a significantly greater prescription of psychotropic drugs by GP-CM (53.7% vs. 22.4%, p < 0.0001).

CONCLUSIONS

Patients consulting a GP-Ho or GP-CM had different motivations for seeking supportive care. There was a significantly greater prescription of psychotropic drugs by GP-CM.

Characteristics of Homeopathy Users among Internal Medicine Patients in Germany

BACKGROUND

Homeopathy use continues to grow in many European countries, and some studies have examined the characteristics of patients using homeopathy within the general population. The aim of this study was to identify predictors for homeopathy use among internal medicine patients.

PATIENTS AND METHODS

A cross-sectional analysis was conducted among all patients being referred to the Department of Internal and Integrative Medicine at Essen, Germany, over a 3-year period. The analysis examined whether patients had used homeopathy for their primary medical complaint before, the perceived benefit, and the perceived harm of homeopathy use. Odds ratios with 95% confidence intervals were calculated using multiple logistic regression analysis.

RESULTS

Of 2,045 respondents, 715 (35.0%) reported having used homeopathy for their primary medical complaint (diagnosis according to the International Statistical Classification of Diseases and Related Health Problems), with 359 (50.2%) reporting perceived benefits and 15 (2.1%) reporting harm. Homeopathy use was positively associated with female gender, high school level education, suffering from fibromyalgia or subthreshold depression, and being fast food abstinent, while patients with osteoarthritis, spinal or other pain, smokers, and patients with a high external-social health locus of control were less likely to use homeopathy.

CONCLUSION

Personal characteristics and health status may impact on the use and the perceived helpfulness of homeopathy.

The development of tumours under a ketogenic diet in association with the novel tumour marker TKTL1: A case series in general practice

Since the initial observations by Warburg in 1924, it has become clear in recent years that tumour cells require a high level of glucose to proliferate. Therefore, a ketogenic diet that provides the body with energy mainly through fat and proteins, but contains a reduced amount of carbohydrates, has become a dietary option for supporting tumour treatment and has exhibited promising results. In the present study, the first case series of such a treatment in general practice is presented, in which 78 patients with tumours were treated within a time window of 10 months. The patients were monitored regarding their levels of transketolase-like-1 (TKTL1), a novel tumour marker associated with aerobic glycolysis of tumour cells, and the patients' degree of adherence to a ketogenic diet. Tumour progression was documented according to oncologists' reports. Tumour status was correlated with TKTL1 expression (Kruskal-Wallis test, P<0.0001), indicating that more progressed and aggressive tumours may require a higher level of aerobic glycolysis. In palliative patients, a clear trend was observed in patients who adhered strictly to a ketogenic diet, with one patient experiencing a stagnation in tumour progression and others an improvement in their condition. The adoption of a ketogenic diet was also observed to affect the levels of TKTL1 in those patients. In conclusion, the results from the present case series in general practice suggest that it may be beneficial to advise tumour patients to adopt a ketogenic diet, and that those who adhere to it may have positive results from this type of diet. Thus, the use of a ketogenic diet as a complementary treatment to tumour therapy must be further studied in rigorously controlled trials.

Open-label observational study of the homeopathic medicine Passiflora Compose for anxiety and sleep disorders

BACKGROUND

Anxiety and sleep disorders (SDS) are frequently treated with psychotropic drugs. Health authorities in France have been advised to improve access to alternative treatments such as homeopathic medicines. Our aim was to describe the socio-demographic characteristics and clinical progression of patients prescribed homeopathic medicine Passiflora Compose (PC) for anxiety and/or SDS.

MATERIAL AND METHODS

This was an open-label, observational study. Randomly selected general practitioners (GPs) known to prescribe homeopathic medicines recruited consecutive patients (≥18-years) prescribed PC. The following data were recorded at inclusion by the GP: socio-demographic data and anxiety severity (Hamilton anxiety rating scale or HAM-A); and by the patients: level of anxiety (STAI Spielberger self-assessment questionnaire) and SDS (Jenkins sleep scale or JSS). Anxiety and SDS were reassessed after 4 weeks of treatment using the same scales.

RESULTS

A total of 639 patients (mean age: 46.3 ± 17.5 years; 78.6% female) were recruited by 98 GPs. Anxiety was present in 85.4% (HAM-A) and 93.3% (Spielberger State) at inclusion (mean scores: 17.8 ± 8.91 and 54.59 ± 11.69, respectively) and SDS was present in 74.0% (mean score: 15.24 ± 5.28). A total of 401 (62.7%) patients received PC alone and 167 (26.1%) PC + psychotropics. After 4 weeks, mean anxiety scores decreased by more than 7, 12 and 6 points (HAM-A, Spielberger State and Trait respectively), and SDS score by more than 4 points (JSS).

CONCLUSION

Anxiety and/or SDS improved significantly in patients included on this study. PC could be an alternative to the use of psychotropic drugs for first intention treatment of anxiety and SDS. Further studies are needed to confirm those results.

[Importance of complementary medicine approaches for patients with prostate cancer]

BACKGROUND

In Germany, many prostate cancer patients use complementary medicine (CM) or have an interest in these treatment approaches; however, the information and consultation situation of cancer patients is insufficient and therefore the Competence Network Complementary Medicine in Oncology (COCON) was launched by the German Cancer Aid Society. One of the projects of the COCON examines the use of CM and the information and counseling needs regarding these topics in various groups of cancer patients. The focus of this article is on the qualitative study reporting selected results for the subgroup of prostate cancer patients.

STUDY DESIGN AND STUDY METHODS

A total of 19 semi-structured qualitative interviews with prostate cancer patients were conducted regarding the use of CM as well as their information and consultation needs.

RESULTS

It was found that the patients interviewed discussed various issues surrounding nutrition, particularly a healthy diet, the selective use of certain foods and the use of dietary supplements. Additional themes mentioned by interviewees were physical exercise, psychological well-being, mistletoe therapy, homeopathy and traditional Chinese medicine. Patients indicated that they wanted more information and counseling opportunities with regards to CM. They also expressed a desire for more holistic care.

CONCLUSION

The results show that prostate cancer patients use a range of CM and have a need for information about CM. Prostate cancer patients are in a special situation because of a regular feedback on the prostate-specific antigen (PSA) value. This should be taken into consideration in consultation with prostate cancer patients regarding CM.

Predictors of complementary and alternative medicine use in cancer care: results of a nationwide multicenter survey in Korea

Background. Although studies have shown that the use of complementary and alternative medicine (CAM) is common in cancer patients, few surveys have assessed CAM use and associated factors in various cancers in Korea. Objectives. We explored factors predicting CAM use among a nationally representative sample of cancer patients. Methods. In total, 2,661 cancer patients were administered questionnaires about their CAM use and factors that might predict CAM use including sociodemographics, clinical and quality-of-life factors, time since diagnosis, trust in physicians, trust in hospitals, satisfaction, and informational needs. Data were analyzed using Pearson's χ² tests and multivariate logistic regression analysis. Results. Overall, 25.5% reported that they had used or were using CAM. Higher income, presence of metastasis, longer time since diagnosis, less trust in hospitals, lower overall satisfaction, and higher degree of informational need were significantly associated with CAM use. Conclusions. The use of CAM in patients with cancer can be interpreted as an attempt to explore all possible options, expression of an active coping style, or expression of unmet needs in the cancer care continuum. Physicians need to openly discuss the use of CAM with their patients and identify whether they have other unmet supportive needs.

Classical homeopathy in the treatment of cancer patients--a prospective observational study of two independent cohorts

BACKGROUND

Many cancer patients seek homeopathy as a complementary therapy. It has rarely been studied systematically, whether homeopathic care is of benefit for cancer patients.

METHODS

We conducted a prospective observational study with cancer patients in two differently treated cohorts: one cohort with patients under complementary homeopathic treatment (HG; n = 259), and one cohort with conventionally treated cancer patients (CG; n = 380). For a direct comparison, matched pairs with patients of the same tumour entity and comparable prognosis were to be formed. Main outcome parameter: change of quality of life (FACT-G, FACIT-Sp) after 3 months. Secondary outcome parameters: change of quality of life (FACT-G, FACIT-Sp) after a year, as well as impairment by fatigue (MFI) and by anxiety and depression (HADS).

RESULTS

HG: FACT-G, or FACIT-Sp, respectively improved statistically significantly in the first three months, from 75.6 (SD 14.6) to 81.1 (SD 16.9), or from 32.1 (SD 8.2) to 34.9 (SD 8.32), respectively. After 12 months, a further increase to 84.1 (SD 15.5) or 35.2 (SD 8.6) was found. Fatigue (MFI) decreased; anxiety and depression (HADS) did not change. CG: FACT-G remained constant in the first three months: 75.3 (SD 17.3) at t0, and 76.6 (SD 16.6) at t1. After 12 months, there was a slight increase to 78.9 (SD 18.1). FACIT-Sp scores improved significantly from t0 (31.0 - SD 8.9) to t1 (32.1 - SD 8.9) and declined again after a year (31.6 - SD 9.4). For fatigue, anxiety, and depression, no relevant changes were found. 120 patients of HG and 206 patients of CG met our criteria for matched-pairs selection. Due to large differences between the two patient populations, however, only 11 matched pairs could be formed. This is not sufficient for a comparative study.

CONCLUSION

In our prospective study, we observed an improvement of quality of life as well as a tendency of fatigue symptoms to decrease in cancer patients under complementary homeopathic treatment. It would take considerably larger samples to find matched pairs suitable for comparison in order to establish a definite causal relation between these effects and homeopathic treatment.

Dose-effect study of Gelsemium sempervirens in high dilutions on anxiety-related responses in mice

INTRODUCTION

This study was designed to investigate the putative anxiolytic-like activity of ultra-low doses of Gelsemium sempervirens (G. sempervirens), produced according to the homeopathic pharmacopeia.

METHODS

Five different centesimal (C) dilutions of G. sempervirens (4C, 5C, 7C, 9C and 30C), the drug buspirone (5 mg/kg) and solvent vehicle were delivered intraperitoneally to groups of ICR-CD1 mice over a period of 9 days. The behavioral effects were assessed in the open-field (OF) and light-dark (LD) tests in blind and randomized fashion.

RESULTS

Most G. sempervirens dilutions did not affect the total distance traveled in the OF (only the 5C had an almost significant stimulatory effect on this parameter), indicating that the medicine caused no sedation effects or unspecific changes in locomotor activity. In the same test, buspirone induced a slight but statistically significant decrease in locomotion. G. sempervirens showed little stimulatory activity on the time spent and distance traveled in the central zone of the OF, but this effect was not statistically significant. In the LD test, G. sempervirens increased the % time spent in the light compartment, an indicator of anxiolytic-like activity, with a statistically significant effect using the 5C, 9C and 30C dilutions. These effects were comparable to those of buspirone. The number of transitions between the compartments of the LD test markedly increased with G. sempervirens 5C, 9C and 30C dilutions.

CONCLUSION

The overall pattern of results provides evidence that G. sempervirens acts on the emotional reactivity of mice, and that its anxiolytic-like effects are apparent, with a non-linear relationship, even at high dilutions.
