Complementary and alternative medicine use among cancer survivors: a population-based study.

ABSTRACT: The use of complementary and alternative medicine (CAM) among cancer survivors is high, yet less is known about reasons behind such use or the communication of CAM with conventional medical providers.Cross-sectional, multivariate logistic regression models were developed to evaluate the similarities and differences between cancer survivors and non-cancer controls in the 2007 National Health Interview Survey with 23,393 participants, including 1,471 cancer survivors.Among cancer survivors, 66.5% reported ever using CAM and 43.3% having used CAM in the past year. When compared with the general population, cancer survivors used CAM more often for general disease prevention, immune enhancement, and for pain (Adjusted Odds Ratio [AOR] 1.27, 95% Confidence Interval [CI] 1.10-1.48; AOR 1.32, 95% CI 1.05-1.62; AOR 1.42, 95% CI 1.05-1.92, respectively). Cancer survivors were more likely to use CAM because of recommendations from their provider (AOR 1.54, 95% CI 1.26-1.88) and were more likely to disclose their CAM use to their provider (AOR 1.45, 95% CI 1.22-1.72).When compared to the general population, cancer survivors were more likely to use CAM and communicate this use with providers, indicating a growing integration of CAM in conventional medical care.Cancer survivors are more likely than the general population to communicate CAM use with providers, suggesting greater integration of CAM use in conventional care. However, the majority of CAM use is still not being communicated to providers, indicating an important area for improvement in patient-centered care.

Project description:BackgroundThe use of complementary and alternative medicines (CAM) among cancer patients varies greatly. The available data suggest an increasing use of CAM over time and a higher prevalence in low- and middle-income countries. However, no reliable data are available from Latin America. Accordingly, we examined the prevalence of CAM use among cancer patients from six Colombian regions.MethodsWe conducted a survey on cancer patients attending comprehensive cancer centres in six capital cities from different regions. The survey was designed based on a literature review and information gathered through focus groups on CAM terminology in Colombia. Independent random samples of patients from two comprehensive cancer centres in every city were obtained. Patients 18 years and older with a histopathological diagnosis of cancer undergoing active treatment were eligible. The prevalence of CAM use is reported as a percentage with the corresponding confidence interval. CAM types are reported by region. The sociodemographic and clinical characteristics of CAM users and non-users were compared using Chi square and t tests.ResultsIn total, 3117 patients were recruited. The average age 59.6 years old, and 62.8% were female. The prevalence of CAM use was 51.7%, and compared to non-users, CAM users were younger, more frequently women, affiliated with the health insurance plan for low-income populations and non-Catholic. We found no differences regarding the clinical stage or treatment modality, but CAM users reported more treatment-related side effects. The most frequent types of CAM were herbal products, specific foods and vitamins, and individually, soursop was the most frequently used product. Relevant variability between regions was observed regarding the prevalence and type of CAM used (range: 36.6% to 66.7%). The most frequent reason for using CAM was symptom management (30.5%), followed by curative purposes (19.5%).ConclusionsThe prevalence of CAM use among cancer patients in Colombia is high in general, and variations between regions might be related to differences in cultural backgrounds and access to comprehensive cancer care. The most frequently used CAM products and practices have little scientific support, suggesting the need to enhance integrative oncology research in the country.

Project description:PurposeWe explored the prevalence and trends of self-reported complementary and alternative medicine use among patients with prostate cancer using CaPSURE™ (Cancer of the Prostate Strategic Urologic Research Endeavor).Materials and methodsA total of 7,989 CaPSURE participants completed questionnaires between 1996 and 2016 on the use of nearly 70 complementary and alternative medicine types. Participants were defined as users if they indicated that they had ever used complementary and alternative medicines. To evaluate trends among 7,696 patients with newly diagnosed prostate cancer we considered complementary and alternative medicine use within 24 months of diagnosis and calculated the percent change in complementary and alternative medicine use between groups defined by the year of diagnosis.ResultsOf patients with prostate cancer 56% reported complementary and alternative medicine use on at least 1 questionnaire. Multivitamin and omega-3 fatty acid use was common at 40% and 24% of patients, respectively. Compared to nonusers greater proportions of complementary and alternative medicine users were college educated, had a higher household income and lived in the West and Midwest. Median prostate specific antigen at diagnosis was 5.8 (IQR 4.4-8.4) and 6.2 ng/ml (IQR 4.7-10.1) among users and nonusers, respectively (p <0.01). Between those diagnosed in 1996 to 2000 and 2011 to 2016, complementary and alternative medicine use increased 128% from 24% to 54%. When comparing participants diagnosed in 2006 to 2010 with those diagnosed in 2011 to 2016, a 108% increase was seen in supplemental vitamin D use and a -48% decrease was seen in supplemental vitamin E use.ConclusionsMany patients with prostate cancer reported complementary and alternative medicine use. Multivitamins and omega-3 fatty acids were commonly ingested and vitamin D use increased dramatically from 2006 to 2010 compared to 2011 to 2016. These data can guide clinical discussions and decision making such as nutritionist referral and help prioritize future research.

Project description:BackgroundThe use of complementary and alternative medicine (CAM) among type 2 diabetes mellitus (T2DM) patients is increasing worldwide. It can affect optimum glycemic management. This study was to determine the rate and influencing factors of CAM use among diabetes patients as well as their effect on glycemic control.MethodsThis cross-sectional study was conducted among T2DM patients attending the outpatient department of Rajshahi Medical College Hospital. It is a tertiary hospital in the northern part of Bangladesh. A face-to-face interview with a pretested structured questionnaire was used for data collection. Chi-square (χ2) test and multivariate logistic regression model were used in this study for data analysis.ResultsOut of 244 T2DM patients, 86 (35.2%) used CAM. Multivariate logistic regression model showed that lower family income group (AOR = 8.7, 95% CI: 2.15-35.22, p-value 0.002), having no institutional education (AOR = 3.4, 95% CI: 1.17-9.87, p-value 0.025) and having diabetes for more than five years (AOR = 2.821, 95% CI: 1.34-5.94, p-value 0.006) were the most influential predictors of CAM use. The most commonly used CAMs were herbal products (67.4%) and homeopathic medicine (37.2%). Most of the CAM users (72%) were influenced by friends, neighbors, and family members. The most common reasons behind CAM use were reported to be the belief that CAM helped control diabetes better (44.2%) and easy availability and lower cost (27.9%). More than half of the users reported the efficacy of CAM as 'nothing significant', while others reported as somewhat good. 14% of CAM users experienced side-effects, especially gastrointestinal upset. It was observed that using CAM was associated with poor glycemic control (AOR = 2.25, 95% CI: 1.14-4.44, p-value 0.018).ConclusionOur study demonstrated that some modifiable factors are associated with the use of CAM, and it cannot maintain good glycemic control. So, patients should be made aware of the ineffectiveness and bad effects of CAM by enhancing educational and poverty-alleviating programs.

Project description:BackgroundThere is growing interest in the use of complementary and alternative medicine (CAM) throughout the world, however previous research done in Japan has focused primarily on CAM use in major cities. The purpose of this study was to develop and distribute a Japanese version of the International Complementary and Alternative Medicine Questionnaire (I-CAM-Q) to assess the use of CAM among people who visit rural Japanese family medicine clinics.MethodsUsing a Japanese version of the International Complementary and Alternative Medicine Questionnaire (I-CAM-Q), a cross-sectional survey was conducted in three rural family medicine clinics. All patients and those accompanying patients who met inclusion criteria were eligible to participate. Data were entered into SPSS Statistics and analyzed for use by age, gender, and location.ResultsOf the 519 respondents who participated in the project, 415 participants reported CAM use in the past 12 months (80.0%). When prayer is excluded, the prevalence of CAM use drops to 77.3% in the past year, or 403 respondents. The most common forms of CAM used by respondents were pain relief pads (n = 170, 32.8%), herbal medicines/supplements (n = 167, 32.2%), and massage by self or family (n = 166, 32.0%). Female respondents, individuals with higher levels of education, and those with poorer overall health status were more likely to use CAM than respondents without these characteristics. Only 22.8% of CAM therapies used were reported to physicians by survey participants.ConclusionsThese data indicate that CAM use in rural Japan is common. The results are consistent with previous studies that show that Japanese individuals are more interested in forms of CAM such as pain relief pads and massage, than in mind-body forms of CAM like relaxation and meditation. Due to the high utilization of certain CAM practices, and given that most CAM users do not disclose their CAM use to their doctors, we conclude that physicians in rural Japan would benefit by asking about CAM use during patient interviews, and by familiarizing themselves with the potential benefits and risks of commonly used CAM modalities.

Project description:Integrative oncology aims to coordinate the delivery of conventional medicine and evidence-supported complementary and alternative medicine (CAM) to patients receiving cancer care. This field developed out of an increased interest in CAM usage among cancer patients. However, CAM use among medically underserved cancer patients remains to be well characterized. We evaluated CAM awareness as well as prevalence and characteristics of CAM use in 170 consecutive, medically underserved cancer patients presenting to a large, academic, inner-city cancer clinic, using a survey tool. Fifty-three participants declined participation and 17 survey results were incomplete. Therefore, 100 survey results were included in the final analysis. There were 65 males and 35 females in the survey with a mean age of 64.2 years. About 98% of the respondents were African American while 2% identified themselves as Hispanic. About 45% of patients had metastatic cancer, 24% had early-stage disease while 31% of patients were not aware of the stage of their cancer. About 55% patients had elementary school or lower level of education while only 16% had a college degree or higher. About 92% of respondents were unemployed. Some knowledge of CAM was reported by 22% of patients, while CAM use was reported in only 16% of patients. Female sex and college degree were significantly associated with CAM use. The most commonly used CAM modality was meditation (56%), followed by herbal remedies (31%), yoga (31%), and acupuncture (12%). Among CAM users, a majority used multiple CAM therapies. All users reported benefit from CAM use. Emotional wellbeing was the most common benefit followed by improvement in treatment related adverse effects, chemotherapy related symptoms, pain, and sleep. Even though the majority of our surveyed patients never used CAM, 90% of non-users were interested in gaining more information about the various CAM options and exploring its use and potential benefits. The majority (70%) wanted their primary oncologist to provide information about CAM options and discuss its safety and potential complementary benefit in management of their cancer and associated symptoms.
