Complementary and alternative medicine use in oncology: a questionnaire survey of patients and health care professionals

Complementary and Alternative Medicine Among Adult Cancer Patients: A Cross-sectional Study

Although there is limited information on efficacy and safety of complementary and alternative medicine (CAM), they are increasingly used by patients with cancer. We aimed to determine the prevalence and predictors of CAM use among a sample of Iranian cancer patients. In this cross-sectional study, conducted in an outpatient cancer clinic, patients with solid tumors or hematologic malignancies in different stages were asked to complete a questionnaire to measure CAM usage. A total of 131 patients with a median age of 58 years (18-86 years) participated in this study. CAM use was reported by 51.9% (n = 68) of the patients. Female gender and higher education level were significantly associated with the use of CAM (OR = 2.47, P value = .01 and OR = 2.55, P value = .02, respectively). Vitamins and minerals were the most frequently used CAM (n = 37, 54.4%). The main reasons for CAM use were to improve immune system and fight cancer (n = 48, 70.6%) followed by relieve side-effects from conventional cancer treatments (n = 26, 38.2%). Although three (4.4%) patients reported side-effects, most patients (n = 53, 77.9%) were satisfied with their CAM use. Among CAM users, 55 (80.9%) patients had reported their CAM use to physician. The CAM use is highly prevalent among adult cancer patients. Health care providers need to raise their awareness on probable disadvantages or benefits of CAMs and discuss these issues with patients.

Attitude of healthcare professionals toward the use of complementary and alternative medication during anti-cancer therapy

OBJECTIVE

Patients with cancer often use complementary and alternative medication (CAM). This research aims to study the current attitude of healthcare professionals toward the use of CAM to improve current care.

METHODS

A questionnaire on both the current practice and opinions about CAM use was sent to healthcare professionals in Amsterdam UMC, who work for the department of hematology or oncology. Oncologists, hematologists, residents, (specialized) nurses, dieticians, (hospital)pharmacists, and pharmacy technicians were asked to participate in this study.

RESULTS

Among eligible healthcare professionals, 77 responded to the questionnaire (34%). Overall, 87% of healthcare professionals indicate it is important to be aware of their patient's CAM use, and all find the potential of drug-herb interactions important. However, more than half of the healthcare professionals inquire about the patient's CAM use infrequently. In addition, only 15% of the healthcare professionals stated they had sufficient knowledge of CAM to advise patients on their use of CAM.

CONCLUSIONS

Healthcare professionals are aware of the potential risks of CAM use in combination with anti-cancer treatment. However, CAM use is not yet discussed with every patient. This may be due to healthcare professionals' lack of knowledge about CAM.

Microbiome-Modifiers for Cancer-Related Fatigue Management: A Systematic Review

OBJECTIVES

This study systematically investigates the evidence regarding the use of probiotics in managing cancer-related fatigue (CRF).

STUDY DESIGN

We conducted a systematic review of randomized controlled trials.

DATA SOURCES

The systematic search encompassed six databases: PubMed, CINHAL, Cochrane Database of Systematic Reviews, Web of Science, Scopus, and EMBASE, covering the period from inception to December 2023. The assessment of risk of bias employed the Cochrane risk of bias tool (RoB 2). A narrative synthesis and an exploratory meta-analysis were conducted to summarize the evidence.

RESULTS

Among 460 records, three studies met the eligibility criteria and were included in the review. These studies involved a total of 284 participants with colorectal and breast cancer. One study demonstrated a marginal improvement in CRF postchemotherapy in colorectal cancer patients using probiotics. Another study, also using probiotics, reported a significant reduction in CRF among colorectal cancer patients undergoing chemotherapy. Additionally, a study employing synbiotics showed a substantial decrease in CRF severity in breast cancer patients receiving chemotherapy.

CONCLUSION

The study presents initial but varied evidence suggesting the potential of probiotics and synbiotics as adjunctive therapies in managing CRF alongside anticancer treatments.

IMPLICATIONS FOR NURSING PRACTICE

In nursing practice, large-scale clinical trials are urgently needed to evaluate the effectiveness of probiotics in treating cancer-related fatigue during cancer therapy. Insights from this review could guide nurses in selecting appropriate probiotic strains and integrating microbiome modifiers into comprehensive care plans, potentially enhancing the quality of life for cancer patients.

Effects of blended learning training for oncology physicians to advise their patients about complementary and integrative therapies: results from the multicenter cluster-randomized KOKON-KTO trial

BACKGROUND

Many oncology physicians are confronted with the topic of complementary and integrative medicine (CIM) by cancer patients. This study examined whether a blended learning (e-learning and a workshop) to train oncology physicians in providing advice on CIM therapies to their cancer patients, in addition to distributing an information leaflet about reputable CIM websites, had different effects on physician-reported outcomes in regard to consultations compared with only distributing the leaflet.

METHODS

In a multicenter, cluster-randomized trial, 48 oncology physicians were randomly allocated to an intervention group (CIM consultation and an information leaflet) or a control group (information leaflet only). After the training, the oncology physicians conducted 297 consultations with their cancer patients. Measurements were assessed at oncology physician, physician-patient-interaction (measured by external reviewers), and patient levels. This analysis focused on the physician outcomes of stress reaction and perceived consultation skill competency. In addition, qualitative interviews were conducted with a subsample of oncology physicians who experienced both, the intervention and control condition.

RESULTS

The oncology physicians in the intervention group showed a lower stress reaction in all measured dimensions after CIM consultations than those in the control group. There was no significant difference between oncology physicians in the intervention and control groups regarding the perceived consultation skill competency (overburden: intervention 1.4 [95% CI: 0.7;2.1]; control 2.1 [95% CI: 1.4;2.7], tension: 1.3 [95% CI: 0.7;2.0] vs. 1.9 [95% CI: 1.3;2.5], and discomfort with consultation situations: 1.0 [95% CI: 0.4;1.7]; vs. 1.7 [95% CI: 1.2;2.3]). The qualitative data showed that only providing the leaflet seemed impersonal to oncology physicians, while the training made them feel well prepared to conduct a full conversation about CIM and provide the information leaflet.

CONCLUSIONS

In our exploratory study providing structured CIM consultations showed positive effects on the perceived stress of oncology physicians, and the training was subjectively experienced as an approach that improved physician preparation for advising cancer patients about CIM, however no effects regarding perceived consultation skill competency were found.

Perception, attitudes, knowledge of using complementary and alternative medicine for cancer patients among healthcare professionals: A mixed-methods systematic review

BACKGROUND

With the rapid increase in the prevalence of cancer worldwide, the utilization of complementary and alternative medicine (CAM) has increased among cancer patients. This review aimed to understand the perception, attitudes, and knowledge of healthcare professionals toward using CAM for cancer patients.

METHODS

A mixed-methods systematic review was undertaken in four databases. Inclusion criteria were primary studies reporting perception, attitudes, and knowledge of healthcare professionals for using CAM for cancer patients were eligible. A mixed-methods convergent synthesis was carried out, and the findings were subjected to a GRADE-CERQual assessment of confidence.

RESULTS

Forty-two studies were chosen. The majority of the studies were quantitative and had less than 100 participants. Most publications were from European countries, and oncology was the highest among the specialties. The review found the following themes: feasibility of having negative adverse effects, low expectations of using CAM among HCPs, potential positive effects of using CAM, specific CAM training may be helpful, no concrete regulations to promote CAM practice, and poor physician-patient communication.

CONCLUSIONS

Nurses had more positive views than other professions; oncologists were concerned regarding herb-drug interactions; integration of CAM into the healthcare system was favorable; HCPs felt the need to participate in specific CAM training; and HCPs agreed that CAM education should be provided more regularly. Future studies should explore the studies views of cancer patients and details of in-depth evidence of CAM in oncology settings.

Endorsement of alternative medicine and vaccine hesitancy among physicians: A cross-sectional study in four European countries

Vaccine hesitancy has become a threat to public health, especially as it is a phenomenon that has also been observed among healthcare professionals. In this study, we analyzed the relationship between endorsement of complementary and alternative medicine (CAM) and vaccination attitudes and behaviors among healthcare professionals, using a cross-sectional sample of physicians with vaccination responsibilities from four European countries: Germany, Finland, Portugal, and France (total N = 2,787). Our results suggest that, in all the participating countries, CAM endorsement is associated with lower frequency of vaccine recommendation, lower self-vaccination rates, and being more open to patients delaying vaccination, with these relationships being mediated by distrust in vaccines. A latent profile analysis revealed that a profile characterized by higher-than-average CAM endorsement and lower-than-average confidence and recommendation of vaccines occurs, to some degree, among 19% of the total sample, although these percentages varied from one country to another: 23.72% in Germany, 17.83% in France, 9.77% in Finland, and 5.86% in Portugal. These results constitute a call to consider health care professionals' attitudes toward CAM as a factor that could hinder the implementation of immunization campaigns.

Cancer Patient Motives and Expectations on Non-medical Practitioners

BACKGROUND/AIM

Non-medical practitioners (NMPs) are an ill-defined group of professionals offering patient diagnostic and therapeutic methods mostly in the field of complementary and alternative medicine (CAM). Despite a lack of quality-assessed structured professional formation, many patients with cancer visit NMPs for advice. This study aimed to learn more on patients' motives and expectations for consulting an NMP.

PATIENTS AND METHODS

A standardized questionnaire was distributed to adult cancer patients addressing attitudes towards NMPs, motives and expectations for consulting an NMP.

RESULTS

A total of 279 patients took part in the survey. Of the included patients 44.8% had already visited an NMP and 16.5% planned to do so. Reasons to visit an NMP were seeking for a supplementary treatment (72.0%) or control of side-effects (68.0%). While the oncologist ranked higher than the NMP in all aspects of physician-patient interaction and patients more often trusted in the oncologist, those patients rating their oncologist rather low in any of these questions significantly more often consulted an NMP. The methods applied or recommended by the NMPs were highly heterogenous ranging from biologically-based methods to mind-body-techniques. Most often used methods were homeopathy (72.0%) vitamin D (62.7%), selenium (42.7%), acupuncture (38.7%).

CONCLUSION

There is a high proportion of cancer patients visiting NMPs mostly for additional treatment. Biologically-based treatments may induce side-effects and interactions, especially as NMPs are not trained on medically accepted cancer treatment and medications. Offering information on CAM and improving the physician-patient relationship are important means to answer unmet needs from the side of the patient.

Traditional and complementary medicine use among cancer patients in Nepal: a cross-sectional survey

BACKGROUND

Traditional and complementary medicine (T&CM) is commonly used in South Asian countries such as Nepal. There are various causes and contributing factors for patients with cancer to consider using T&CM. However, little is known about the use of T&CM among the cancer population in this region.

METHODS

The study followed a cross-sectional design using a structured survey questionnaire. Survey participants were recruited from two National hospitals in Kathmandu, Nepal. The survey instrument comprised 30 questions, including variables on demographics, use of T&CM, and perceived level of disease severity, and cancer treatment. Chi-square test and logistic regression were used for data analysis using SPSS ver. 23.0.

RESULTS

Of 908 participants, 31.6% used one or more modalities of T&CM after a cancer diagnosis. The most commonly used T&CM was Ayurveda (46.5%), followed by yoga (32.4%). About 46% of T&CM users discussed their use with their doctors. The main source of information on T&CM was their family members and relatives (55.7%). Cancer type (head and neck cancer OR: 2.30, CI: 1.23-4.29; abdominal cancer OR: 2.69, CI: 1.47-4.95; lung cancer OR: 5.88, CI: 2.69-12.89), cancer stage (Stage I OR: 1.92¸CI: 1.14-3.25; Stage II OR: 1.76, CI: 1.06-2.94), and the patients' self-rated disease severity (high perceived severity OR: 1.50, CI: 1.05-2.16) were strong predictors of T&CM use.

CONCLUSION

This study underlined that despite the widespread use of T&CM among cancer patients in Nepal, most patients obtained information on T&CM from informal sources and did not disclose their use to physicians. To ensure the safe use of T&CM modalities, physicians should integrate questions on T&CM use into routine patient assessments in order to facilitate active communication and improve the quality of care.

Acceptance and use of complementary and alternative medicine among medical specialists: a 15-year systematic review and data synthesis

BACKGROUND

Complementary and Alternative Medicine (CAM) has gained popularity among the general population, but its acceptance and use among medical specialists have been inconclusive. This systematic review aimed to identify relevant studies and synthesize survey data on the acceptance and use of CAM among medical specialists.

METHODS

We conducted a systematic literature search in PubMed and Scopus databases for the acceptance and use of CAM among medical specialists. Each article was assessed by two screeners. Only survey studies relevant to the acceptance and use of CAM among medical specialists were reviewed. The pooled prevalence estimates were calculated using random-effects meta-analyses. This review followed both PRISMA and SWiM guidelines.

RESULTS

Of 5628 articles published between 2002 and 2017, 25 fulfilled the selection criteria. Ten medical specialties were included: Internal Medicine (11 studies), Pediatrics (6 studies), Obstetrics and Gynecology (6 studies), Anesthesiology (4 studies), Surgery (3 studies), Family Medicine (3 studies), Physical Medicine and Rehabilitation (3 studies), Psychiatry and Neurology (2 studies), Otolaryngology (1 study), and Neurological Surgery (1 study). The overall acceptance of CAM was 52% (95%CI, 42-62%). Family Medicine reported the highest acceptance, followed by Psychiatry and Neurology, Neurological Surgery, Obstetrics and Gynecology, Pediatrics, Anesthesiology, Physical Medicine and Rehabilitation, Internal Medicine, and Surgery. The overall use of CAM was 45% (95% CI, 37-54%). The highest use of CAM was by the Obstetrics and Gynecology, followed by Family Medicine, Psychiatry and Neurology, Pediatrics, Otolaryngology, Anesthesiology, Internal Medicine, Physical Medicine and Rehabilitation, and Surgery. Based on the studies, meta-regression showed no statistically significant difference across geographic regions, economic levels of the country, or sampling methods.

CONCLUSION

Acceptance and use of CAM varied across medical specialists. CAM was accepted and used the most by Family Medicine but the least by Surgery. Findings from this systematic review could be useful for strategic harmonization of CAM and conventional medicine practice.

Perceptions of homeopathy in supportive cancer care among oncologists and general practitioners in France

OBJECTIVES

In France, homeopathy is the most frequently used complementary therapy in supportive care in oncology (SCO); its use is steadily increasing. However, data is limited about the perception and relevance of homeopathy by oncologists and general practitioners (GPs) both with and without homeopathic training (HGPs and NHGPs, respectively). Our aim was to evaluate French physicians' perceptions of homeopathy to clarify its place in SCO through two original observation survey-based studies.

MATERIALS AND METHODS

Two cross-sectional surveys of French physicians were conducted involving (1) 150 specialist oncologists; (2) 97 HGPs and 100 NHGPs. Questions evaluated physician attitudes to homeopathy and patterns of use of homeopathic therapies in patients requiring SCO. Survey responses were described and analyzed on the basis of physician status.

RESULTS

Ten percent of oncologists stated they prescribe homeopathy; 36% recommend it; 54% think that homeopathy is potentially helpful in SCO. Two-thirds of the NHGPs sometimes prescribe homeopathy in the context of SCO and 58% regularly refer their patients to homeopathic doctors. HGPs have a positive perception of homeopathy in SCO.

CONCLUSIONS

Homeopathy is viewed favorably as an integrated SCO therapy by the majority of French physicians involved with cancer patients-oncologists and GPs. Symptoms of particular relevance include fatigue, anxiety, peripheral neuropathy, sleep disturbance, and hot flashes. In such clinical situations, response to conventional therapies may be suboptimal and homeopathy is considered a reliable therapeutic option. These two studies highlight the fact that homeopathy has gained legitimacy as the first complementary therapy in SCO in France.

A pre-post evaluation of oncology healthcare providers' knowledge, attitudes, and practices following the implementation of a complementary medicine practice guideline

PURPOSE

Complementary medicine (CM) use is prevalent among cancer patients, yet it is often not assessed by oncology healthcare providers (HCPs). The purpose of this study was to evaluate oncology HCPs' knowledge, attitudes, and practices surrounding CM use before and after the implementation of a practice guideline focusing on standardizing assessment and documentation of CM.

METHODS

Oncology HCPs across a provincial cancer agency were invited to participate in the study. The implementation strategy included an initial education session for HCPs and standardized CM assessment forms. Pre-post surveys assessing knowledge, attitudes, and practices related to CM were completed by HCPs prior to attending the education session and following the 4-month implementation period. Paired t-tests were conducted to determine differences between baseline and follow-up surveys.

RESULTS

A total of 31 oncology HCPs completed both baseline and follow-up surveys, with over 3700 patient CM assessment forms being completed during the 4-month study period. At the end of the study, HCPs reported greater CM knowledge (p < 0.001), readiness to support cancer patients' CM decisions (p = 0.002), and willingness to consult with another HCP about CM (p = 0.004). No significant change in HCPs' reported attitudes towards CM, or other clinical practices related to CM were observed.

CONCLUSION

Implementing a practice guideline, including a CM education session and a standardized assessment form, was found to improve oncology HCPs' self-reported CM knowledge and readiness to answer cancer patients' questions about CM. The findings provide support for future knowledge translation research aimed at standardizing how CM is addressed within cancer care settings.

Effects of training oncology physicians advising patients on complementary and integrative therapies on patient-reported outcomes: A multicenter, cluster-randomized trial

BACKGROUND

Many patients with cancer do not disclose complementary medicine use but want their physician's advice on this matter. This study evaluated whether using blended learning (e-learning plus a workshop) to train oncology physicians in providing advice on complementary and integrative medicine (CIM) therapies to their patients with cancer, in addition to distributing an information leaflet on reputable CIM websites, had different effects on patient-reported outcomes for the consultation than only distributing the leaflet.

METHODS

In this multicenter, cluster-randomized trial, patients from private practices/hospital departments, recruited by 48 oncology physicians randomly allocated to an intervention group (CIM consultation plus information leaflet) or a control group (information leaflet), received CIM information. Patient-reported outcomes included satisfaction (Patient Satisfaction With Information on Cancer Treatment), readiness to make a decision (Preparation for Decision Making), and physician-patient communication (European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire and Communication 26 [EORTC QLQ-COMU26]) for the consultation. Qualitative interviews were conducted with a physician subsample.

RESULTS

A total of 291 patients (128 in the intervention group and 169 in the control group) advised by 41 physicians participated. Patients in the intervention group rated physician-patient communication higher on all EORTC QLQ-COMU26 scales (mean total score, 84.3 [95% CI, 79.5-89.2] vs 73.6 [95% CI, 69.3-78.0]; P = .002), were more satisfied with the advice (mean, 4.2 [95% CI, 4.0-4.4] vs 3.7 [95% CI, 3.5-3.8]; P < .001), and were readier to make a decision (mean, 63.5 [95% CI, 57.4-69.6] vs 53.2 [95% CI, 47.8-58.7]; P = .016) than the control group. Physicians who reported patients in both settings seemed satisfied with the advice given.

CONCLUSIONS

This study evaluated a novel education intervention for training oncology physicians in providing CIM advice in routine care. Providing structured CIM consultations had positive effects on patient satisfaction, readiness to make decisions, and physician-patient communication.

Complementary and integrative medicine mention and recommendations: A systematic review and quality assessment of lung cancer clinical practice guidelines

BACKGROUND

Complementary and integrative medicine (CIM) use is widely sought by those diagnosed with cancer, with up to 50% of lung cancer patients seeking these therapies in the United States. The purpose of this study was to identify the quantity and assess the quality of CIM recommendations in clinical practice guidelines (CPGs) for the treatment and/or management of lung cancer.

METHODS

A systematic review was conducted to identify lung cancer CPGs. MEDLINE, EMBASE and CINAHL were searched from 2008 to 2018, along with the Guidelines International Network and the National Center for Complementary and Integrative Health websites. Eligible guidelines containing recommendations for the treatment and/or management of lung cancer were assessed with the Appraisal of Guidelines, Research and Evaluation II (AGREE II) instrument.

RESULTS

From 589 unique search results, 4 guidelines mentioned CIM, of which 3 guidelines made CIM recommendations. Scaled domain percentages from highest to lowest were: scope and purpose (82.4% overall, 76.9% CIM), clarity and presentation (96.3% overall, 63.0% CIM), editorial independence (61.1% overall, 61.1% CIM), rigour of development (62.5% overall, 54.9% CIM), stakeholder involvement (66.7% overall, 42.6% CIM) and applicability (29.9% overall, 18.8% CIM). Quality varied within and across guidelines.

CONCLUSION

Guidelines that scored well could serve as a framework for discussion between patients and healthcare professionals regarding use of CIM therapies in the context of lung cancer. Guidelines that scored lower could be improved according to the AGREE II instrument, with insight from other guidelines development resources.

Comparison of eight screening tools to detect interactions between herbal supplements and oncology agents

INTRODUCTION

Patients with cancer are increasingly using herbal supplements, unaware that supplements can interact with oncology treatment. Herb-drug interaction management is critical to ensure optimal treatment outcomes. Several screening tools exist to detect drug-drug interactions, but their performance to detect herb-drug interactions is not known. This study compared the performance of eight drug-drug interaction screening tools to detect herb-drug interaction with anti-cancer agents.

METHODS

The herb-drug interaction detection performance of four subscription (Micromedex, Lexicomp, PEPID, Facts & Comparisons) and free (Drugs.com, Medscape, WebMD, RxList) drug-drug interaction tools was assessed. Clinical relevance of each herb-drug interaction was determined using Natural Medicine and each drug-drug interaction tool. Descriptive statistics were used to calculate sensitivity, specificity, positive predictive value, and negative predictive value. Linear regression was used to compare performance between subscription and free tools.

RESULTS

All tools had poor sensitivity (<0.20) for detecting herb-drug interaction. Lexicomp had the highest positive predictive value (0.98) and best overall performance score (0.54), while Medscape was the best performing free tool (0.52). The worst subscription tools were as good as or better than the best free tools, and as a group subscription tools outperformed free tools on all metrics. Using an average subscription tool would detect one additional herb-drug interaction for every 10 herb-drug interactions screened by a free tool.

CONCLUSION

Lexicomp is the best available tool for screening herb-drug interaction, and Medscape is the best free alternative; however, the sensitivity and performance for detecting herb-drug interaction was far lower than for drug-drug interactions, and overall quite poor. Further research is needed to improve herb-drug interaction screening performance.

Complementary medicine use during cancer treatment and potential herb-drug interactions from a cross-sectional study in an academic centre

Complementary medicine (CM) is used by one third to one half of cancer patients throughout the world. The objective of this study was to describe the prevalence of CM use and the potential for interactions with cancer treatments in an academic oncology centre. A cross-sectional study was conducted among patients undergoing current cancer treatment. Among 132 included patients, 56% had used CM since their cancer diagnosis and 45% were using CM during cancer treatment at the time of the survey. The main CM used were green tea (35%), herbal tea (35%), homeopathy (27%), dietary supplements (27%), and herbal medicines (27%). A small majority of patients (58%) spontaneously mentioned the use of CM to their oncologist. Of 42 identified combinations of concomitant use of biologically based CM and anticancer agents among the study patients, the potential for pharmacokinetic interactions of clinical relevance was not expected in 17 combinations (40%), hypothetical and deemed unlikely in 23 (55%), and of probable low clinical relevance in 2 (5%). Considering the high prevalence of CM use, active enquiries should be made by healthcare professionals to detect symptoms that may relate to CM tolerance and effects or that suggest interactions between CM and cancer treatments.

Use of complementary and alternative medicine among breast cancer patients in Hungary: A descriptive study

BACKGROUND AND PURPOSE

This study aimed to explore the prevalence of the use of complementary and alternative medicine (CAM) before diagnosis and during oncology therapy, and reveal the disclosure of CAM use among Hungarian breast cancer patients.

MATERIALS AND METHODS

In a cross-sectional survey a self-administered questionnaire was used covering patients' demographics, oncology-related variables and various aspects of CAM use. Data were collected from 135 patients. Data analysis included descriptive analysis and Chi-square tests.

RESULTS

The prevalence of CAM use was 52.6% before diagnosis while it was 84.4% during therapy. The most commonly used CAM practices before diagnosis and during therapy were vitamins/minerals (37%, 60%, respectively) and herbs (31.9%, 78.5%, respectively). The frequency of CAM use before diagnosis was higher among more educated patients (p < 0.001) and those living in cities (p = 0.001) while during therapy it was higher among patients with higher income (p = 0.020). Over 40% of the patients informed their physician about each CAM practice they used.

CONCLUSION

Besides conventional medicine, CAM practices are also regarded as an important part of therapy by cancer patients. The higher frequency of CAM use during therapy and the relatively modest disclosure towards physicians indicate a greater need for patients' education regarding CAM practices.

Complementary and alternative medicine use in cancer: A systematic review

BACKGROUND AND PURPOSE

Complementary and alternative medicine (CAM) use in cancer is increasing. The purpose of this study was to systematically review the literature to determine demographic profiles and prevalence and reasons for use in cancer patients.

METHODS

In this systematic review, the databases OVID, PubMed, and Scopus were searched for studies on CAM use in cancer between 2009 and June 2018.

RESULTS

The results showed that an average of 51% of cancer patients used CAM. Common independent demographic characteristics associated with CAM use were younger, female cancer patients, having higher education, earning a higher income and having previously used CAM. Frequent reasons for use, grouped into themes were shown to be to influence their cancer and general health and to treat complications of the cancer or therapy.

CONCLUSION

The review provides an insight and will serve to better inform health professionals on how this population is using CAM.

Health-care providers' perspectives on traditional and complementary alternative medicine of childhood cancer in Kenya

PURPOSE

Traditional and complementary alternative medicine (TCAM) use is rising globally. In many African countries, TCAM has been a way of life as the first and last resort remedy for many ailments, including cancer. Health-care providers (HCP) should address this need properly. This study explores HCP perspectives on TCAM in Kenya.

METHODS

This cross-sectional study used questionnaires. HCP involved in the care of children with cancer at a Kenyan academic hospital were interviewed.

RESULTS

In total, 155 HCP (response rate 79%) participated. Only 18% of HCP were positive about TCAM use. However, most HCP (85%) use TCAM themselves. More doctors (90%) than other HCP (56%) think that chemotherapy can cure cancer (P < 0.001).Thirty-three percent of HCP believe a combination of TCAM and chemotherapy is the best way to cure cancer, while 56% think that usefulness of TCAM is underestimated in conventional medicine. Self-prayer is regarded as most effective (58%) and safe (76%). Most harmful is witchcraft (80%). Most HCP (71%) think their knowledge about safety and efficacy of TCAM is inadequate. HCP think that their cancer patients use TCAM (97%) and that it is important that parents inform them about this (97%). However, only 5% of HCP always openly discuss TCAM with parents.

CONCLUSIONS

HCP need to improve their knowledge of TCAM and facilitate open communication about TCAM with families so parents feel safe to discuss their interest in it.

Integrative oncology and complementary medicine cancer services in Australia: findings from a national cross-sectional survey

Background

Individuals living with and beyond a cancer diagnosis are increasingly using complementary therapies and medicines (CM) to enhance the effectiveness of cancer treatment, manage treatment-related side effects, improve quality-of-life, and promote self-efficacy. In response to the increasing use and demand for CM by cancer patients, interest in the implementation of Integrative Oncology (IO) services that provide CM alongside conventional cancer care in Australia and abroad has developed. The extent that cancer services in Australia are integrating CM is uncertain. Thus, the aim of this study was to identify IO services in Australia and explore barriers and facilitators to IO service provision.

Methods

A national, cross-sectional survey of healthcare organisations was conducted in 2016. Organisations in the public and private sectors, including not-for-profit organisations that provided cancer care in hospital or community setting, were included.

Results

A response rate of 93.2% was achieved (n = 275/295). Seventy-one organisations (25.8%) across all states/territories, except the Northern Territory, offered IO albeit in a limited amount by many. Most common IO services included massage, psychological-wellbeing, and movement modalities in hospital outpatient or inpatient settings. There were only a few instances where biological-based complementary medicine (CM) therapies were prescribed. Funding was often mixed, including patient contributions, philanthropy, funding by the organisation, and volunteer practitioners.

Of the 204 non-IO providers, 80.9% had never provided any IO service. Overwhelmingly, the most common barrier to IO was a lack of funding, followed by uncertainty about patient demand, choice of services, and establishing such services. Less-common barriers were a lack of evidence, and support from oncologists or management. More funding, education and training, and building the evidence-base for CM were the most commonly suggested solutions.

Conclusion

IO is increasingly being provided in Australia, although service provision remains limited or non-existent in many areas. Mismatches appear to exist between low IO service provision, CM evidence, and high CM use by cancer patients. Greater strategic planning and policy guidance is indicated to ensure the appropriate provision of, and equitable access to IO services for all Australian cancer survivors.

Characterizing Websites That Provide Information About Complementary and Integrative Health: Systematic Search and Evaluation of Five Domains

BACKGROUND

In recent years, there has been an increase in the utilization of complementary and integrative health (CIH) care, and an increase in information-seeking behavior focused on CIH. Thus, understanding the quality of CIH information that is available on the internet is imperative. Although there have been a limited number of studies evaluating the quality of websites providing information about specific CIH-related topics, a broad evaluation of CIH websites has not been conducted.

OBJECTIVE

This study was designed to fill that gap. We set out to assess website quality in 5 CIH domains: (1) acupuncture, (2) homeopathy, (3) massage, (4) reiki, and (5) yoga. This study aimed to 1) characterize the websites by type and quality; 2) evaluate website characteristics which may affect readers' perceptions, specifically message content, structural features, and presentation style, and 3) investigate the extent to which harms, benefits and purposes of use are stated on websites.

METHODS

This study employed a systematic search strategy to identify websites in each of the target domains to be evaluated. The websites were then classified by type, and a set of checklists focusing on quality, message content, structural features, and presentation style was used to evaluate the websites. Lastly, we performed content analysis to identify harms, benefits, and perceived purposes of use.

RESULTS

There were similarities across domains regarding their overall quality and their message content. Across all domains, a high proportion of websites received strong scores in terms of ownership, currency, interactivity and navigability. Scores were more variable concerning authorship, balanced presentation of information and the use of sources of information. However, there were differences regarding their structural features and presentation style. Acupuncture and reiki sites tended to include more external links, and yoga, fewer. There was variation across domains in the extent to which the websites contained domain-specific terminology. Websites tended to provide an extensive list of potential benefits, while reporting of harms was scarce.

CONCLUSIONS

This is the first study to perform a multidimensional assessment of websites in multiple CIH domains. This review showed that while there are similarities among websites of different CIH domains, there are also differences. The diverse distribution of website types suggests that, regardless of CIH domain, the public encounters information through many different types of media, and it would be useful to consider how the presentation of this content may differ depending on the medium. The characteristics for which variability exist are areas that warrant greater attention from researchers, policy makers, clinicians and patients. There is also a need to better understand how individuals may interact with CIH websites, and to develop tools to assist people to interpret the CIH-related information that they encounter.

Evidence for and Against Green Tea and Turmeric in the Management of Chronic Lymphocytic Leukemia

Complementary and alternative medicine (CAM) is a diverse group of medical and health care systems, practices, and products that are not generally considered part of conventional medicine. Chronic lymphocytic leukemia (CLL) is the most common leukemia diagnosed in the western hemisphere, and 16.5% to 66% of patients have reported using CAM. Most patients use spiritual/mind-body techniques and high doses of vitamins and herbs (most commonly polyphenols, including teas). We have reviewed the reported data on green tea and turmeric use in CLL patients.

Perspectives of Oncology Nurses on Complementary and Alternative Medicine in Turkey: A Cross-Sectional Survey

In Turkey, between 22.1% and 84.1% of patients with cancer use complementary and alternative medicine (CAM). However, few CAM-related studies have focused on the perspective of oncology nurses. This study aimed to determine the knowledge, attitudes, and practices of Turkish oncology nurses regarding CAM. A descriptive cross-sectional survey of 127 participants was conducted in Ankara, Turkey. A semistructured questionnaire including characteristics, knowledge, attitudes, and practices of oncology nurses toward CAM was administered to participants. We found that more than half of nurses (54.0%) surveyed had no information on CAM modalities. Most oncology nurses (81.1%) used audiovisual media sources to obtain CAM information. Many nurses (81.3%) reported not using any CAM in cancer care, and only 26.8% recommended CAM to patients. Most nurses used CAM to accelerate wound healing (19.7%) and to manage symptoms, including constipation and diarrhea (8.8%) and anxiety (7.9%). Music (52.8%), massage (49.6%), and exercise (48.8%) were stated to be beneficial. Important barriers to use CAM for patients with cancer involved a lack of knowledge (60.6%); needing physician approval to apply any CAM methods to patients (52.1%); legal and institutional issues (47.2%); and limited educational, training, or certificate programs (44.1%). There is a need for increased knowledge about CAM by oncology nurses, considering their vital role in symptom management of patients with cancer. This can be achieved through solving legal and institutional problems, structured and comprehensive education/training programs, and the integration of CAM therapy into cancer care guidelines.

Use of Complementary Traditional Chinese Medicines by Adult Cancer Patients in Taiwan: A Nationwide Population-Based Study

BACKGROUND

Many patients with cancer seek complementary and alternative medicine treatments. We investigated the use of traditional Chinese medicine (TCM) by adult cancer patients in Taiwan.

METHODS

We reviewed the Registry for Catastrophic Illness Patients Database of Taiwan, and included all adult patients diagnosed cancer, based on the International Classification of Diseases (ninth revision), from 2001 to 2009 and followed until 2011. This database allowed categorization of patients as TCM users (n = 74 620) or non-TCM users (n = 508 179). All demographic and clinical claims data were analyzed.

RESULTS

Compared with non-TCM users, TCM users were younger and more likely to be female, white-collar workers, and reside in highly urbanized areas. The average interval between cancer diagnosis and TCM consultation was 15.3 months. The most common cancer type was breast cancer in TCM users (19.4%), and intrahepatic bile duct cancer in non-TCM users (13.6%). The major condition for which TCM users visited clinics were endocrine, nutritional and metabolic diseases, and immunity disorders (23.2%). A total of 33.1% of TCM users visited TCM clinics more than 9 times per year and their time from diagnosis to first TCM consultation was 5.14 months. The most common TCM treatment was Chinese herbal medicine. The common diseases for which cancer patients sought TCM treatment were insomnia, malaise and fatigue, dizziness and headache, gastrointestinal disorders, myalgia and fasciitis, anxiety, and depression. Overall, TCM users had a lower adjusted hazard ratio (aHR) for mortality (aHR = 0.69, 95% CI = 0.68-0.70) after adjustment for age, sex, urbanization of residence, occupation, annual medical center visits, and annual non-medical center visits.

CONCLUSIONS

This study provides an overview of TCM usage among adult cancer patients in Taiwan. TCM use varied among patients with different types of cancer. Physicians caring for cancer patients should pay more attention to their patients' use of complementary TCM.

Discrepant Views of Oncologists and Cancer Patients on Complementary and Alternative Medicine in a Chinese General Hospital

PURPOSE

Complementary and alternative medicine (CAM) has been widely used by cancer patients but rarely discussed by oncologists. This study was designed to evaluate the communication gap between China's oncologists and cancer patients on CAM.

METHODS

Two parallel cross-sectional studies assessed 83 oncologists and 402 cancer patients on CAM communication between patients and oncologists, and attitudes toward CAM use and clinical decisions about CAM.

RESULTS

A majority (75.1%) of the cancer patients (302/402) were identified as CAM users within the most recent three months while 77.6% of the cancer patients (312/402) were identified as CAM users since diagnosis of cancer. Oncologists and patients responded differently ( P < .001) on CAM communications. Both oncologists and patients expected that CAM could improve the immune system. They both agreed that oncologists usually discouraged their patients from using CAM. Regarding the effectiveness of CAM, cancer patients were more likely to believe that CAM was effective while oncologists had more concerns about adverse effects of CAM use. CAM use by patients was predicted by disease duration (≥9 months) in the multivariable logistic regression model.

CONCLUSION

China's oncologists and cancer patients may hold discrepant views on CAM. China's oncologists are encouraged to improve their knowledge on CAM and to initiate more discussions with their patients regarding effective and the safe use of CAM.

Complementary and Alternative Medicine Use in Minority and Medically Underserved Oncology Patients: Assessment and Implications

Introduction: Complementary and alternative medicine (CAM) use in minority and medically underserved oncology patients is not well documented. We assessed knowledge and utilization of CAM in a sample of these patients receiving treatment at an urban community hospital. Methods: Patients with cancer were interviewed using an electronic application that depicted specific CAM therapies. Patients were questioned on their knowledge and utilization of therapies, deterrents to use, and interest in using these therapies if they were made available. Results: Patients (n = 165) reported a high awareness and use of CAM therapies. CAM use was highest for prayer (85%), relaxation (54%), special diet (29%), meditation (19%), and massage (18%). Patients’ interest in using CAM was high for nearly all therapies. Lack of adequate knowledge and cost of use were reported as deterrents to use. Female patients reported higher use of aromatherapy relative to males (37.1% vs 19.4%, P = .02); those with higher education reported greater use of relaxation (60.8% vs 28.6%, P = .02); non-Hispanics reported higher use of relaxation relative to Hispanics (63.5% vs 44.2%, P = .03), and African American patients reported higher use of relaxation relative to White patients (69.2% vs 50%, P = .03). Conclusions: CAM use in minority and medically underserved cancer patients is common, but not professionally guided; thus, concerns remain regarding its safe use. Our data underscore the importance of patient-physician dialogue regarding CAM use in this patient population, and interest in access to the medically guided integration of evidence-based CAM therapies.

National survey of China's oncologists' knowledge, attitudes, and clinical practice patterns on complementary and alternative medicine

It is common for cancer patients to use complementary and alternative medicine (CAM). This study was designed to explore China's oncologists’ knowledge, attitudes and clinical practices regarding CAM use by their patients. An online survey was conducted of China's oncologists. Among 11,270 participants who completed the online survey, 6,007 (53.3%) were identified as oncologists. Most were men (75.2%), with a mean age of 33.4 (standard deviation: 6.5) years. The 6,007 oncologists discussed with 36.5% of their patients about CAM. Most of them (75.6%) did not want to initiate discussions due to lack of knowledge on CAM. Oncologists estimated that 40.0% of their patients used CAM treatments. Oncologists reported that 28.7% of their patients underwent anticancer therapy with the concurrent use of CAM. Four out of five of the responding oncologists self-reported inadequate knowledge and only 22.0% reported receiving professional education on CAM. Nearly half (44.9%) of the oncologists believed CAM treatment was effective for symptoms and treatment of cancer. Physician factors associated with initiating discussions with patients about CAM use included sex, age (≥ 33 years), medical license for traditional Chinese medicine, enough knowledge and professional education experience. China's oncologists infrequently discussed with their patients about CAM due to lack of knowledge. Most of the oncologists did not encourage CAM use.

Key stakeholder perspectives on the barriers and solutions to pharmacy practice towards complementary medicines: an Australian experience

BACKGROUND

Although pharmacists are entrusted to play a role in ensuring the safe and appropriate use of all medicines, in general, the inclusion of complementary medicines (CMs) into their professional practice has not been observed. The purpose of this study was to explore the perceptions and opinions of pharmacists and 8 key stakeholder leaders regarding the barriers that hinder pharmacists from providing care related to the use of CMs by patients/consumers and to identify solutions that would support pharmacists' in extending their role in this area.

METHODS

Semi-structured key informant interviews were conducted with 2 practicing pharmacists, 1 pharmacy owner, 1 key representative of a pharmacist professional organization, 1 key representative of a consumer advocacy group, 1 key representative of a medical professional organization, 1 key representative from a complementary medicine practitioner professional organization, 1 leader within a pharmacy school, 2 senior staff from a regulatory authority, and 1 key representative of the complementary medicine industry in Australia.

RESULTS

A total of 9 barriers were identified in this study. Barriers including a lack of CMs knowledge, doubts about the evidence-base, a lack of research skills and access to reliable and reputable information dominated the discussions. A total of 7 solutions were proposed. Of those, the integration of CMs curricula into under-graduate and professional pharmacy education, and defining a clearer role for pharmacists' standard of practice were considered the most important. Apposing opinions about the role of naturopaths in pharmacies were identified..

CONCLUSION

It is anticipated that pharmacists will be required to formalise a role in ensuring the safe and appropriate use of complementary medicines to fulfil their professional and ethical responsibilities. However, pharmacists in general are not ready to take up this extended role. Individual key stakeholder groups have considered the existing barriers and have proposed solutions that are isolated measures. To facilitate further developments related to CMs and the professional practice of pharmacy, collaborative efforts between key stakeholders are needed to strategically plan and execute an extended role in a unified manner.

Complementary and Alternative Medicine: Italian Validation of a Questionnaire on Nurses' Personal and Professional Use, Knowledge, and Attitudes

BACKGROUND

Patients are showing an increasing interest in the use of complementary and alternative medicine (CAM). Most nurses are open to the adoption of CAM into clinical nursing practice, but they may experience a lack of knowledge about the safe and effective use of these therapies. Several studies concerning nurses' knowledge and attitudes toward CAM have been published, but only in one, the authors (Shorofi and Arbon) used a validated questionnaire. In Italy, there are no validated questionnaires to investigate this aspect of nursing practice.

PURPOSE

To test the psychometric properties of the Italian Shorofi and Arbon questionnaire for use with Italian nurses.

METHODS

A forward-backward translation method was used to translate the questionnaire from English to Italian. Content validity, face validity and reliability were established.

RESULTS AND CONCLUSIONS

This study examined the potential usefulness of the Shorofi and Arbon questionnaire for the evaluation of CAM knowledge of Italian speaking nurses, which showed good content validity and good reliability.

Gynecologic oncologists' attitudes and practices relating to integrative medicine: results of a nationwide AGO survey

Purpose

The growing popularity and acceptance of integrative medicine is evident both among patients and among the oncologists treating them. As little data are available regarding health-care professionals’ knowledge, attitudes, and practices relating to the topic, a nationwide online survey was designed.

Methods

Over a period of 11 weeks (from July 15 to September 30, 2014) a self-administered, 17-item online survey was sent to all 676 members of the Research Group on Gynecological Oncology (Arbeitsgemeinschaft Gynäkologische Onkologie) in the German Cancer Society. The questionnaire items addressed the use of integrative therapy methods, fields of indications for them, advice services provided, level of specific qualifications, and other topics.

Results

Of the 104 respondents (15.4%) using integrative medicine, 93% reported that integrative therapy was offered to breast cancer patients. The second most frequent type of tumor in connection with which integrative therapy methods were recommended was ovarian cancer, at 80% of the participants using integrative medicine. Exercise, nutritional therapy, dietary supplements, herbal medicines, and acupuncture were the methods the patients were most commonly advised to use.

Conclusion

There is considerable interest in integrative medicine among gynecological oncologists, but integrative therapy approaches are at present poorly implemented in routine clinical work. Furthermore there is a lack of specific training. Whether future efforts should focus on extending counseling services on integrative medicine approaches in gynecologic oncology or not, have to be discussed. Evidence-based training on integrative medicine should be implemented in order to safely guide patients in their wish to do something by themselves.

Curcumin suppresses epithelial-to-mesenchymal transition and metastasis of pancreatic cancer cells by inhibiting cancer-associated fibroblasts

Pancreatic cancer is one of the most lethal malignancies and the fourth leading cause of cancer-related deaths worldwide, because of its aggressive and highly metastatic ability even in its early stages. Cancer-associated fibroblasts (CAFs) have been reported to be vital to pancreatic cancer progression via regulating tumorigenesis and metastasis. Studies have shown that CAFs also mediate epithelial-to-mesenchymal transition (EMT) in tumor cells. Curcumin has recently been reported to have anticancer effects by modulating pathways involved in cancer progression. Therefore, we hypothesized that curcumin might inhibit EMT by targeting CAFs in pancreatic cancer. In this study, we show that the CAF-mediated enhancement of pancreatic cancer cell migration and metastasis was blocked by curcumin. In conclusion, our data provide the first evidence that curcumin inhibits the migration and metastasis of pancreatic cancer cells by reducing the mesenchymal characteristics of CAFs, which reverses the EMT phenotypes of pancreatic cancer cells.

Complementary and alternative medicine use amongst patients with cardiovascular disease in Singapore

BACKGROUND

Data on complementary and alternative medicine (CAM) use in patients with cardiovascular disease (CVD) are lacking. We aim to investigate the prevalence of CAM use among patients with CVD attending a tertiary centre for cardiovascular care, their attitudes and beliefs towards CAM, and factors associated with CAM usage.

METHODS

A cross-sectional, self-administered written survey was conducted on consecutive patients attending outpatient cardiovascular clinics at our tertiary institution over 2 months from June to July 2014. Information gathered included demographic data and various aspects of CAM use.

RESULTS

A total of 768 responses (562 males, mean age 57 ± 13 years, 74 % Chinese, 6 % Malay, 14 % Indian) were included. The prevalence of CAM use in the cohort was 43.4 % (333/768). Biologically-based systems (29.4 %) was the most common type of CAM used. Some patients (19.0 %) used multiple types of CAM simultaneously. External influences (78.1 %) were cited more than internal influences (47.8 %) to affect CAM use. Malay ethnicity (compared to Chinese) was the only significant negative multivariate predictor of CAM use (OR = 0.531 (95 % CI 0.147 to 0.838), p = 0.018). A significantly higher proportion of CAM users compared to non-CAM users were non-compliant to medications (35.6 %, n = 114 vs. 20.5 %, n = 84, p < 0.001) and consults (41.4 %, n = 130 vs. 28.1 %, n = 112, p < 0.001) respectively.

CONCLUSION

The usage of CAM is prevalent amongst our patients with CVD. CAM use was associated with poorer reported compliance to medications and consults. Understanding the factors influencing CAM use amongst CVD patients provides medical professionals with an opportunity to better discuss CAM use and potentially enhance the patient-physician interaction.

Mechanisms and therapeutic effectiveness of pulsed electromagnetic field therapy in oncology

Cancer is one of the most common causes of death worldwide. Available treatments are associated with numerous side effects and only a low percentage of patients achieve complete remission. Therefore, there is a strong need for new therapeutic strategies. In this regard, pulsed electromagnetic field (PEMF) therapy presents several potential advantages including non-invasiveness, safety, lack of toxicity for non-cancerous cells, and the possibility of being combined with other available therapies. Indeed, PEMF stimulation has already been used in the context of various cancer types including skin, breast, prostate, hepatocellular, lung, ovarian, pancreatic, bladder, thyroid, and colon cancer in vitro and in vivo. At present, only limited application of PEMF in cancer has been documented in humans. In this article, we review the experimental and clinical evidence of PEMF therapy discussing future perspectives in its use in oncology.

Information and Training Needs Regarding Complementary and Alternative Medicine: A Cross-sectional Study of Cancer Care Providers in Germany

BACKGROUND

Among cancer care providers (CCPs), lack of knowledge constitutes an important barrier to the discussion of complementary and alternative medicine (CAM) use with patients. This study assessed CCPs' needs and preferences regarding CAM information and training (I&T).

METHODS

An online survey was completed by 209 general practitioners, 437 medical specialists, 159 oncology nurses and medical assistants, and 244 psychologists and social workers engaged in cancer care. Latent class analysis (LCA) was used to identify subgroups of individuals with distinct preference patterns regarding I&T content.

RESULTS

CCPs prefer CAM I&T to be provided as lectures, information platforms on the internet, workshops, and e-mail newsletters. Concerning subject matters, many CCPs considered CAM therapy options for the treatment of a variety of cancer disease- and therapy-related symptoms to be very important (75%-72% of the sample); the same applies to an "overview of different CAM therapies" (74%). LCA identified 5 latent classes (LCs) of CCPs. All of them attached considerable importance to "medical indication," "potential side effects," and "tips for usage." LCs differed, however, in terms of overall importance ratings, the perceived importance of "patients' reasons" for using specific CAM therapies, "case examples," and "scientific evidence." Notably, the 5 LCs were clearly present in all 4 occupational groups.

CONCLUSIONS

CAM I&T should provide CCPs with an overview of different CAM therapies and show how CAM might help in treating symptoms cancer patients frequently demonstrate (eg, fatigue). Moreover, I&T programs should be flexible and take into account that individual information needs vary even within the same occupational group.

Expected and perceived efficacy of complementary and alternative medicine: A comparison views of patients with cancer and oncologists

BACKGROUND & AIMS

This study sought to identify discrepancies between the expectations of patients with cancer and oncologists regarding the efficacy of complementary and alternative medicines (CAMs), and to determine how patients evaluate CAM efficacy after its use.

METHODS

Data from the Cancer Patient Experience Study, a nationwide survey, were used. Seven subdivided efficacy domains were included in the survey. An oncologist-patient matching analysis was done to assess the concordance of CAM efficacies between oncologists and patients with cancer. In addition, the patients' expectations of CAM efficacies were compared before and after use.

RESULTS

Out of 719 participants, 201 patients with cancer (28.0%) reported using CAMs. The patients with cancer generally tended to be more positive about CAM efficacies than the oncologists. The largest discrepancy in efficacy perception was found in the efficacy domain of survival benefit, which included complete disease remission and prolonged survival. Many patients reported that they did not experience the positive efficacy they had anticipated before use. However, a substantial proportion of patients indicated that CAMs were as effective as they had expected, even though there is little evidence supporting the CAM efficacies.

CONCLUSIONS

There was a marked discrepancy and a lack of concordance in expectations of CAM efficacy between patients with cancer and oncologists. Better communication between the patients and oncologists regarding CAM efficacy would be needed to make the patients to have shared expectations, and to reduce unnecessary CAM use.

Chinese Herbal Medicine as an Adjunctive Therapy for Breast Cancer: A Systematic Review and Meta-Analysis

Chinese herbal medicine (CHM) has been widely used as an adjunctive therapy for breast cancer, while its efficacy remains unexplored. The purpose of this study is to evaluate the efficacy of CHM combined with chemotherapy for breast cancer. The study results showed that CHM combined with chemotherapy significantly increased tumor response and KPS as compared to using chemotherapy alone (RR = 1.36; 95% CI = 1.24–1.48; P < 0.00001; RR = 1.38; 95% CI = 1.26–1.52; P < 0.00001, resp.). Besides, CHM as an adjunctive therapy significantly reduced the nausea and vomiting at toxicity grade of III–IV (RR = 0.37; 95% CI = 0.27–0.52; P < 0.00001). Moreover, the combined therapy significantly prevented the decline of WBC in patients under chemotherapy at toxicity grade of III–IV (RR = 0.49; 95% CI = 0.34–0.69; P < 0.00001) and prevented the decline of platelet at toxicity grade of III–IV or I–IV (RR = 0.29; 95% CI = 0.12–0.73; P = 0.008; RR = 0.77; 95% CI = 0.63–0.94; P = 0.009, resp.). This study suggests that CHM combined with chemotherapy in comparison with chemotherapy alone can significantly enhance tumor response, improve KPS, and alleviate toxicity induced by chemotherapy in breast cancer patients. However, a firm conclusion could not be reached due to the lack of high quality trials and large-scale RCTs, so further trials with higher quality and larger scale are needed.

The Effectiveness of Hologram Bracelets in Reducing Chemotherapy-Induced Nausea and Vomiting Among Adult Patients With Cancer

BACKGROUND

Chemotherapy-induced nausea and vomiting (CINV) affects cancer patients' quality of life, despite the provision of antiemetic medication.

OBJECTIVES

The aim of this study is to assess the clinical effectiveness of the hologram bracelet in the management of CINV among adult patients with cancer.

METHODS

An experimental, double-blinded design spanning 3 courses of chemotherapy was used; 175 oncology patients were randomly assigned to 3 groups: placebo (n = 53), control (n = 54), and intervention (hologram bracelet) (n = 68). Daily diaries were used to detect the severity and the frequency of CINV and to detect the frequency of using antiemetic medications. The Functioning Living Index-Emesis was used to examine the impact of CINV on the activities of daily living.

RESULTS

Significant CINV differences existed between groups. The mean total Functioning Living Index-Emesis score was significantly lower in the intervention group for total vomiting and total nausea.

CONCLUSION

Hologram bracelet use among patients with cancer had a positive effect on CINV. The level of CINV decreased and activity of daily living scores increased. However, effects varied among the types of CINV.

IMPLICATIONS FOR PRACTICE

Further study is recommended to explore the benefits of the bracelet.

Comparing Health-Care Providers' Perspectives on Complementary and Alternative Medicine in Childhood Cancer Between Netherlands and Indonesia

BACKGROUND

Use of complementary and alternative medicine (CAM) is common among patients with childhood cancer. Health-care providers (HCP) should address this need properly. Geographical and cultural differences seem likely. This study explores perspectives on CAM of HCP involved in the care of children with cancer in Netherlands and Indonesia. Health beliefs, components of CAM, encouraging or discouraging CAM, and knowledge about CAM were assessed.

PROCEDURE

We conducted a cross-sectional study using semi-structured questionnaires at a Dutch and Indonesian academic hospital.

RESULTS

A total of 342 HCP participated: 119 Dutch (response rate 80%) and 223 Indonesian (response rate 87%). Chemotherapy can cure cancer according to more Dutch than Indonesian HCP (87% vs. 53% respectively, P < 0.001). Combination of chemotherapy and CAM is the best way to cure cancer according to more Indonesian than Dutch HCP (45% vs. 25%, P < 0.001). Dutch and Indonesian HCP recommend and discourage CAM use differently. Most Dutch (77%) and Indonesian HCP (84%) consider their knowledge about CAM to be inadequate (P = ns). Fewer Dutch doctors than other HCP want to learn more about CAM (51% vs. 76%, P = 0.007), whereas there is no significant difference in eagerness to learn about CAM between Indonesian doctors (64%) and other HCP (72%).

CONCLUSIONS

Indonesian HCP have more positive views about CAM than their Dutch colleagues. Both Dutch and Indonesian HCP consider their knowledge about CAM to be inadequate. Therefore, education programs about CAM tailored to the needs of HCP are recommended, knowing that CAM is used frequently.

Chinese herbal medicine as maintenance therapy for improving the quality of life for advanced non-small cell lung cancer patients

OBJECTIVE

The purpose of the study was to assess the efficacy and safety of using Chinese herbal medicine (CHM) as maintenance therapy considering the survival of advanced non-small-cell lung cancer (NSCLC) patients after first-line conventional platinum-based chemotherapy.

DESIGN

An open-label, randomized, controlled trial.

SETTING

Four hospitals in China.

INTERVENTIONS AND MAIN OUTCOME MEASURES

A total of 106 patients were eligible and randomly divided into two groups from four hospitals in China. Both groups received the best supporting care (BSC). Additionally, patients in the trial group were given CHM every day until the disease became aggravated or the patients resigned. The study took both progression-free survival (PFS) and quality of life (QOL) as the primary outcomes to comprehensively evaluate the effect of the treatment. QOL was measured by the Functional Assessment of Cancer Therapy-Lung (FACT-L) 4.0 questionnaire. Side effects and safety were evaluated at the same time.

RESULTS

Of the 106 patients, 99 completed the study. After treatment and follow-up for PFS, there were no significant differences in the median PFS time and the 6-month PFS probability between the two groups. However, the 3-month PFS probability in the trial group was significantly higher than that in the control group (FAS, PPS: P<0.01). For QOL, there were significant differences between the two groups in the following: physical well-being, emotional well-being, functional well-being, lung cancer symptom domain and total score of the FACT-L4.0 (FAS, PPS: P<0.05). There was no significant difference in the social well-being domain. No serious adverse side effects to the treatment were observed.

CONCLUSIONS

CHM is well tolerated and may improve the QOL of advanced NSCLC patients. CHM is worth studying in future investigations.

Andrographis paniculata elicits anti-invasion activities by suppressing TM4SF3 gene expression and by anoikis-sensitization in esophageal cancer cells

Esophageal cancer is the sixth most common cancer in male causing death worldwide. It is usually diagnosed at advanced stage with high postoperative recurrence and systemic metastasis, which leads to poor prognosis. The potential inhibitory effect of herbal medicines on metastasis of esophageal cancer has drawn researchers' great attention. In the present study, the anti-invasion activities of Andrographis paniculata (AP) have been evaluated in two esophageal cancer cell lines, EC-109 and KYSE-520, as well as human microvascular endothelial cells (HMEC-1). The anti-tumor and anti-metastatic activities of AP were also evaluated in human esophageal xenograft-bearing mouse models. Our results demonstrated for the first time that aqueous extract of AP inhibited the motility and invasion of esophageal cancer cells, which is the initial step of metastasis, without cytotoxicity. Anoikis resistance has also been reversed in AP-treated cancer cells. Besides, the expression of metastasis-related gene TM4SF3 in EC-109 cells was significantly decreased in AP extract-treated cells in a concentration-dependent manner. Furthermore, the anti-tumor and anti-metastatic efficacies in subcutaneous and intraperitoneal esophageal xenograft-bearing mice were demonstrated after oral administration of AP aqueous extract for 3 weeks. Last but not least, the active component, isoandrographolide, responsible for the anti-migratory activity was firstly revealed here. In conclusion, the AP aqueous extract exerted inhibitory activities on the migration and anoikis resistance of esophageal cancer cells EC-109 and KYSE-520, as well as suppressed the proliferation and motility of endothelial cells. Combining the mentioned effects may account for the anti-tumor and anti-metastasis effects of AP aqueous extract in xenograft-bearing mice. The findings in the present study further enhance the understanding of the therapeutic mechanisms of the herb AP, which may lead to clinical applications.

Surveys of Cancer Patients and Cancer Health Care Providers Regarding Complementary Therapy Use, Communication, and Information Needs

BACKGROUND

Complementary therapies (CTs) are increasingly utilized by cancer patients. Nonetheless, patients report insufficient support from health care practitioners (HCPs) and there is a general lack of patient-practitioner communication about CT use. Best care practices suggest that HCPs should address the needs of patients, including CT use. This study examined current practices of patients and HCPs as well as their interactions relating to CTs.

METHODS

A total of 481 cancer outpatients and 100 HCPs completed questionnaires. Patient questions addressed CT use and information needs; HCP questions addressed knowledge, opinions and beliefs about complementary and alternative medicine. Patient-practitioner communication around CT was also examined.

RESULTS

47% of patients reported using CTs since diagnosis. Many commenced CT use to improve quality of life (65%) based on recommendations from family or friends. Patients acknowledged the need for trusted sources of information and would attend a hospital-based education program (72%). HCPs reported limited training about CTs but most (90%) expressed interested in receiving more training. The majority of HCPs (>80%) reported limited knowledge about the role of CTs in cancer care or evidence to support CT use. Questions about communication and interactions revealed that 80% of patients reported not having had an HCP speak to them about CTs. However, 63% of HCPs reported addressing CT use.

CONCLUSION

Results demonstrate a need for improved CT education and training for patients and HCPs. increasing HCP knowledge and clinical skills will ensure patients' information needs about CTs are acknowledged and attended to, thereby providing safer and comprehensive cancer care.

A systematic review of barriers to optimal outpatient specialist services for individuals with prevalent chronic diseases: what are the unique and common barriers experienced by patients in high income countries?

Health utilization and need assessment data suggest there is considerable variation in access to outpatient specialist care. However, it is unclear if the types of barriers experienced are specific to chronic disease groups or experienced universally. This systematic review provides a detailed summary of common and unique barriers experienced by chronic disease groups when accessing and receiving care, and a synthesized list of possible health service initiatives to improve equitable delivery of optimal care in high-income countries. Quantitative articles describing barriers to specialist outpatient services were retrieved from CINAHL, MEDLINE, Embase, and PyscINFO. To be eligible for review, studies: were published from 2002 to May 2014; included samples with cancer, diabetes mellitus, osteoporosis, arthritis, ischaemic heart disease, stroke, asthma, chronic pulmonary disorder (COPD) or depression; and, were conducted in high-income countries. Using a previously validated model of access (Penchansky and Thomas' model of fit), barriers were grouped according to five overarching domains and defined in more detail using 33 medical subject headings. Results from reviewed articles, including the scope and frequency of reported barriers, are conceptualized using thematic analysis and framed as possible health service initiatives. A total of 3181 unique records were screened for eligibility, of which 74 studies were included in final analysis. The largest proportion of studies reported acceptability barriers (75.7 %), of which demographic disparities (44.6 %) were reported across all diseases. Other frequently reported barriers included inadequate need assessment (25.7 %), information provision (32.4 %), or health communication (20 %). Unique barriers were identified for oncology, mental health, and COPD samples. Based on the scope, frequency and measurement of reported barriers, eight key themes with associated implications for health services are presented. Examples include: common accommodation and accessibility barriers caused on service organization or physical structure, such as parking and appointment scheduling; common barriers created by poor coordination of care within the healthcare team; and unique barriers resulting from inadequate need assessment and referral practices. Consideration of barriers, across and within chronic diseases, suggests a number of specific initiatives are likely to improve the delivery of patient-centered care and increase equity in access to high-quality health services.

The effect of complementary and alternative medicine on quality of life, depression, anxiety, and fatigue levels among cancer patients during active oncology treatment: phase II study

BACKGROUND

During the past decade, there has been growing interest in complementary and alternative medicine (CAM) among cancer patients and it is being integrated more frequently within conventional cancer centers. The long-term effect of mind-body therapies on quality of life (QoL), depression, anxiety, and fatigue was tested prospectively in this study.

PATIENTS AND METHODS

Cancer patients who received six weekly sessions of CAM during their oncological treatments participated in the study. The Hospital Anxiety and Depression Scale (HADS), Brief Fatigue Inventory (BFI) and QoL-EORTC-C30 were completed during the intervention and follow-up period.

RESULTS

Over a two-year period, 163 patients entered the study, 135 of whom completed all six CAM sessions. An improvement was demonstrated in the median of BFI from 4.8 to 3.9 (p < 0.001), HADS-Anxiety from 8 to 7 (p < 0.001) and HADS-Depression from 7 to 6 (p < 0.001) after 12 weeks. In addition, the median of global QoL improved from 50 to 67 (p < 0.001), and a significant improvement was noticed in several parameters on the functioning and symptoms scales of the QoL-EORTC-C30.

CONCLUSION

Cancer patients who completed six weekly sessions of CAM improved significantly on measured outcomes, regardless of their demographic characteristics.

National survey of US oncologists' knowledge, attitudes, and practice patterns regarding herb and supplement use by patients with cancer

PURPOSE

Patients with cancer commonly use complementary and alternative medicine, including herbs and supplements (HS), during cancer treatment. This national survey explored oncologists' knowledge, attitudes, and practice patterns regarding HS use by their patients.

METHODS

A survey was sent by mail and e-mail to a random sample of 1,000 members of the American Society for Clinical Oncology. The questions covered several topics: communication patterns, attitudes about HS, education about HS, response to HS use among hypothetical patients with cancer, knowledge of HS adverse effects, and demographic information.

RESULTS

Among eligible oncologists, 392 (42%) responded to the questionnaire. Most were white (75%) men (71%), with a mean age of 48 years (standard deviation, 9.8 years). On average, oncologists discussed use of HS with 41% of their patients; only 26% of discussions were initiated by the oncologist. Two of three oncologists indicated they did not have enough knowledge to answer questions from patients regarding HS, and 59% had not received any education about the topic. Physician factors associated with having initiated discussions with patients about the use of HS included female sex, higher self-reported knowledge, prior education about HS, increased knowledge about HS adverse effects and interactions, and estimating that > 40% of one's patients with cancer use HS.

CONCLUSION

Fewer than one half of oncologists are initiating discussions with patients about HS use, and many indicate that lack of knowledge and education is a barrier to such discussions. Improving physician education about HS may facilitate more physician-patient communication about this important topic.

Complementary and alternative medicine use amongst Malaysian orthopaedic oncology patients

BACKGROUND

Although studies have shown that a large proportion of cancer patients use CAM, no study on CAM use amongst orthopaedic oncology patients has been published. Therefore, this study aims to determine the prevalence, characteristics and factors associated with CAM use amongst orthopaedic oncology patients.

METHODS

All consecutive consenting patients/parents who presented at the Orthopaedic Oncology Clinic, University Malaya Medical Centre (1st January to 31st December 2013) were interviewed using a structured questionnaire.

RESULTS

Overall, one hundred sixty-eight of the 274 patients recruited (61.3%) had used CAM at some time during their current illness. The prevalence of CAM used was 68% (123/181) for patients with malignant tumours and 48.4% (45/93) for patients with benign tumours. The most popular CAMs were biological-based therapies (90.5%), followed by mind-body techniques (40.5%). The most frequently used biological therapies were mega/multivitamins (31%), snakehead (Chana striatus) (28%) and sea cucumber (Stichopus horrens) (18%); whereas prayers (31%) and holy water (13%) dominated the mind-body category. Common reasons for CAM use were to improve physical well-being (60.1%), try out everything that would help (59.5%) and to enhance wound-healing (39.3%). Independent predictors for CAM use in multivariate analysis were paediatric patients [OR 2.46; 95% CI 0.99-6.06; p = 0.05], malignant tumours [OR 1.90; 95% CI 1.12-3.25; p = 0.018] and patients who underwent surgery [OR 2.06; 95% CI 1.15-3.69; p = 0.015]. Majority patients started taking CAMs following suggestions from family members (53%) and friends (49%). Sixty-six percent of patients felt they actually benefitted from CAM and 83.3% were satisfied/very satisfied. Only 5 patients reported side-effects. Majority of CAM users planned to continue CAM use or recommend it to others. However, only 31.5% of patients disclosed their CAM usage to their doctors.

CONCLUSIONS

This survey revealed a high prevalence of CAM usage amongst orthopaedic oncology patients, with majority patients expressing satisfaction towards CAM. Oncologists should proactively ask patients about CAM to prevent potential adverse effects, as most patients do not share this information with them.
