Reasons for and Characteristics Associated With Complementary and Alternative Medicine Use Among Adult Cancer Patients: A Systematic Review

Purpose: To conduct a systematic review of reasons for and sociodemographic and disease characteristics associated with complementary and alternative medicine (CAM) use in cancer patients. Methods: Eligible studies were identified by searching the following databases: Alt Health Watch, AMED, CINAHL, CancerLit, PremMEDLINE, MEDLINE, Pub-Med, Ingenta, EMBASE, and Health Star, as well as reference lists in review articles. Only English-language articles published between 1994 and 2004 were included. Search terms included CAM and oncology/cancer , decision making and CAM and oncology/cancer , treatment decision making and CAM and oncology/cancer , and health care choices and CAM and oncology/cancer . Results: Fifty-two eligible studies were identified and summarized. These studies were conducted in 14 different countries, with the largest number of studies being completed in the United States (34.6%). A therapeutic response, wanting control, a strong belief in CAM, CAM as a last resort, and finding hope were the most commonly cited reasons for using CAM. Age, socioeconomic status, and gender were the dominant characteristics associated with CAM use. Conclusion: Reasons for and characteristics associated with CAM use among cancer patients have been studied extensively. Future CAM research among cancer patients should focus on identifying decision-making processes and building theoretical decision-making models. These can be used in the development of decisional aids for patients when confronted with the choice to use CAM as part of their cancer treatment.

Beliefs related to breast health practices: the perceptions of South Asian women living in Canada.

Breast cancer is becoming a major concern for many South Asian women. Clinical observations of women from a South Asian community living in Canada revealed an under use of early detection strategies. The purpose of this qualitative ethnoscience study was to examine breast health practices from the perspective of South Asian women to provide a foundation for the development of culturally suitable breast health services for this group. Open-ended interviews were conducted with a convenience sample of 50 South Asian women over the age of 30 who had not been diagnosed with breast cancer. Adequate representation of the main religious groups (i.e. Sikh, Hindu, Muslim and Christian) was ensured through sampling techniques. Analysis of translated interviews involved identification of themes and the development of a taxonomy to represent relationships among emerging cultural themes and domains. Four central domains of beliefs related to breast health practices were identified: beliefs about a womans calling, beliefs about cancer, beliefs about taking care of your breasts and beliefs about accessing services. These beliefs hold important implications for how health promotion strategies should be structured and offered, In particular, attention must be paid to the language that is used to talk about breast cancer, the importance of the role of the family in womens health decisions and traditions related to using narratives to share information and advice.

Clinical Practice Guidelines on the Use of Integrative Therapies as Supportive Care in Patients Treated for Breast Cancer

BACKGROUND The majority of breast cancer patients use complementary and/or integrative therapies during and beyond cancer treatment to manage symptoms, prevent toxicities, and improve quality of life. Practice guidelines are needed to inform clinicians and patients about safe and effective therapies. METHODS Following the Institute of Medicines guideline development process, a systematic review identified randomized controlled trials testing the use of integrative therapies for supportive care in patients receiving breast cancer treatment. Trials were included if the majority of participants had breast cancer and/or breast cancer patient results were reported separately, and outcomes were clinically relevant. Recommendations were organized by outcome and graded based upon a modified version of the US Preventive Services Task Force grading system. RESULTS The search (January 1, 1990-December 31, 2013) identified 4900 articles, of which 203 were eligible for analysis. Meditation, yoga, and relaxation with imagery are recommended for routine use for common conditions, including anxiety and mood disorders (Grade A). Stress management, yoga, massage, music therapy, energy conservation, and meditation are recommended for stress reduction, anxiety, depression, fatigue, and quality of life (Grade B). Many interventions (n = 32) had weaker evidence of benefit (Grade C). Some interventions (n = 7) were deemed unlikely to provide any benefit (Grade D). Notably, only one intervention, acetyl-l-carnitine for the prevention of taxane-induced neuropathy, was identified as likely harmful (Grade H) as it was found to increase neuropathy. The majority of intervention/modality combinations (n = 138) did not have sufficient evidence to form specific recommendations (Grade I). CONCLUSIONS Specific integrative therapies can be recommended as evidence-based supportive care options during breast cancer treatment. Most integrative therapies require further investigation via well-designed controlled trials with meaningful outcomes.

Beyond convention: describing complementary therapy use by women living with breast cancer

Using a descriptive survey design, 52 women living with breast cancer were interviewed to explore their use of complementary therapy and the relationships between complementary therapy use and key demographic variables and health beliefs. Sixty-seven percent of the women reported complementary therapy use, with meditation/relaxation therapies, vitamins and spiritual healing being the three most frequently reported treatments. Women using complementary therapies were more likely to have completed post-secondary education than women using only conventional medical treatment (chi 2 = 7.1, P = 0.008). Preferred decisional role was found to be significantly associated with the use of complementary therapies (chi 2 = 11.7, P = 0.003); women using complementary therapies preferred a more active/collaborative role in treatment decisions than women using only conventional medical treatment. No significant associations were found between complementary therapy use and beliefs about cause of cancer, treatments, satisfaction with health care providers, and perceived quality of life. The findings point to the pervasiveness of complementary therapy use by women living with breast cancer and contradict past research which has supported a distinct demographic profile of complementary therapy users and associated belief system.

Bridging the gap: decision-making processes of women with breast cancer using complementary and alternative medicine (CAM)

Goals of workThe purpose of this study was to explore the personal and social processes women with breast cancer engaged in when making decisions about complementary and alternative medicine (CAM). The overall aim was to develop a conceptual model of the treatment decision-making process specific to breast cancer care and CAM that will inform future information and decision support strategies.Materials and methodsGrounded theory methodology explored the decisions of women with breast cancer using CAM. Semistructured interviews were conducted with 20 women diagnosed with early-stage breast cancer. Following open, axial, and selective coding, the constant comparative method was used to identify key themes in the data and develop a conceptual model of the CAM decision-making process.Main resultsThe final decision-making model, Bridging the Gap, was comprised of four core concepts including maximizing choices/minimizing risks, experiencing conflict, gathering and filtering information, and bridging the gap. Women with breast cancer used one of three decision-making styles to address the paradigmatic, informational, and role conflict they experienced as a result of the gap they perceived between conventional care and CAM: (1) taking it one step at a time, (2) playing it safe, and (3) bringing it all together.ConclusionsWomen with breast cancer face conflict and anxiety when making decisions about CAM within a conventional cancer care context. Information and decision support strategies are needed to ensure women are making safe, informed treatment decisions about CAM. The model, Bridging the Gap, provides a conceptual framework for future decision support interventions.

Perinatal Beliefs and Practices of Immigrant Punjabi Women Living in Canada

OBJECTIVE To describe new immigrant Punjabi womens perinatal experiences and the ways that traditional beliefs and practices are legitimized and incorporated into the Canadian health care context. DESIGN Naturalistic qualitative descriptive. PARTICIPANTS/SETTING Fifteen first-time mothers who had immigrated in the past 5 years to Canada from Punjab, India, and had given birth to a healthy infant in the past 3 months in a large urban center in British Columbia, Canada. Five health professionals and community leaders also took part in a focus group to confirm the study findings and to offer recommendations. RESULTS Three major categories emerged: the pervasiveness of traditional health beliefs and practices related to the perinatal period (e.g., diet, lifestyle, and rituals), the important role of family members in supporting women during the perinatal experiences, and the positive and negative interactions women had with health professionals in the Canadian health care system. CONCLUSIONS Change is required at the levels of the health professional, the heath care system, and the community to ensure that culturally safe care is provided to immigrant Punjabi women and their families during the perinatal period, which is an important and sensitive period of interaction with the Canadian health care system.

Canadian Network for Mood and Anxiety Treatments (CANMAT) 2016 Clinical Guidelines for the Management of Adults with Major Depressive Disorder Section 5. Complementary and Alternative Medicine Treatments

Background: The Canadian Network for Mood and Anxiety Treatments (CANMAT) conducted a revision of the 2009 guidelines by updating the evidence and recommendations. The scope of the 2016 guidelines remains the management of major depressive disorder (MDD) in adults, with a target audience of psychiatrists and other mental health professionals. Methods: Using the question-answer format, we conducted a systematic literature search focusing on systematic reviews and meta-analyses. Evidence was graded using CANMAT-defined criteria for level of evidence. Recommendations for lines of treatment were based on the quality of evidence and clinical expert consensus. “Complementary and Alternative Medicine Treatments” is the fifth of six sections of the 2016 guidelines. Results: Evidence-informed responses were developed for 12 questions for 2 broad categories of complementary and alternative medicine (CAM) interventions: 1) physical and meditative treatments (light therapy, sleep deprivation, exercise, yoga, and acupuncture) and 2) natural health products (St. John’s wort, omega-3 fatty acids; S-adenosyl-L-methionine [SAM-e], dehydroepiandrosterone, folate, Crocus sativus, and others). Recommendations were based on available data on efficacy, tolerability, and safety. Conclusions: For MDD of mild to moderate severity, exercise, light therapy, St. John’s wort, omega-3 fatty acids, SAM-e, and yoga are recommended as first- or second-line treatments. Adjunctive exercise and adjunctive St. John’s wort are second-line recommendations for moderate to severe MDD. Other physical treatments and natural health products have less evidence but may be considered as third-line treatments. CAM treatments are generally well tolerated. Caveats include methodological limitations of studies and paucity of data on long-term outcomes and drug interactions.

Women's decision making about risk-reducing strategies in the context of hereditary breast and ovarian cancer: a systematic review.

Women who have a mutation in the BRCA1 or BRCA2 genes have up to an 87% lifetime risk of breast cancer and up to a 40% lifetime risk of ovarian cancer. Cancer prevention and early detection strategies are often considered by these women to address this heightened risk. Risk-reducing strategies include risk-reducing mastectomy and oophorectomy, breast and ovarian cancer screening, and chemoprevention. This systematic literature review summarizes the factors and contexts that influence decision making related to cancer risk-reducing strategies among women at high-risk for hereditary breast and ovarian cancer. In the 43 published research articles reviewed, three main types of factors are identified that influence high-risk women’s decisions about risk-reducing strategies: a) medical and physical factors, b) psychological factors and c) social context factors. How these factors operate in women’s lives over time remains unknown, and would best be elucidated through prospective, longitudinal research, as well as qualitative research.

Perceptions of cannabis as a stigmatized medicine: a qualitative descriptive study

BackgroundDespite its increasing prevalence and acceptance among the general public, cannabis use continues to be viewed as an aberrant activity in many contexts. However, little is known about how stigma associated with cannabis use affects individuals who use cannabis for therapeutic purposes (CTP) and what strategies these individuals employ to manage associated stigma. The aim of this Canadian study was to describe users’ perceptions of and responses to the stigma attached to using CTP.MethodsTwenty-three individuals who were using CTP for a range of health problems took part in semi-structured interviews. Transcribed data were analyzed using an inductive approach and comparative strategies to explore participants’ perceptions of CTP and identify themes.ResultsParticipant experiences of stigma were related to negative views of cannabis as a recreational drug, the current criminal sanctions associated with cannabis use, and using cannabis in the context of stigmatizing vulnerability (related to existing illness and disability). Strategies for managing the resulting stigma of using CTP included: keeping CTP ‘undercover’; educating those who did not approve of or understand CTP use; and using cannabis responsibly.ConclusionsUnderstanding how individuals perceive and respond to stigma can inform the development of strategies aimed at reducing stigma associated with the use of CTP and thereby address barriers faced by those using this medicine.
