Behaviors and Attitudes toward the Use of Complementary and Alternative Medicine among Korean Cancer Patients

Bridging the gap: attitudes and practices toward complementary and alternative medicine among oncology patients and healthcare professionals in Croatia

The prevalence of complementary and alternative medicine (CAM) use among oncology patients ranges from 30 to 80%, particularly higher in the United States compared to Europe. However, limited research exists on the attitudes of healthcare professionals and oncology patients toward CAM, especially within Western evidence-based medical settings. This study aims to address this gap by assessing CAM use prevalence among healthcare professionals and oncology patients and analyzing their cognitive, affective, and behavioral attitudes. Additionally, it explores the influence of sociodemographic factors and personal experiences on these attitudes. A cross-sectional survey was conducted between November 2022 and May 2023 at University Hospital Center Sisters of Mercy, Zagreb, Croatia. The study included 832 participants: 411 oncology patients and 421 healthcare professionals (100 physicians, 321 nurses/technicians). Data were collected using modified versions of the Health Belief Questionnaire (CHBQ) and Integrative Medicine Attitude Questionnaire (IMAQ). Statistical analysis included descriptive methods and tests such as Chi-square, Mann-Whitney U, Kruskal-Wallis, ANOVA, and post hoc Tukey tests. The results showed that 55.6% of oncology patients and 32.2% of healthcare workers had used CAM at least once. Oncology patients were more likely to use CAM than healthcare professionals, and among healthcare professionals, nurses/technicians used CAM more frequently than physicians. Significant differences in attitudes were observed based on sociodemographic factors. Positive attitudes were more common among women, older adults, individuals with lower education levels, nurses/technicians, those with longer work experience, non-oncology healthcare workers, believers, and those with lower incomes. Marital status and place of residence showed no significant effect. This study highlights a gap between cancer patients' frequent, unsupervised CAM use and healthcare providers' often skeptical attitudes, particularly among physicians. The findings underscore the need for targeted education for healthcare professionals, development of CAM management guidelines in oncology, and fostering open dialogue between patients and providers to optimize outcomes. Longitudinal research is recommended to explore CAM's impact on clinical outcomes.

The Relationship Between Cancer Patients' Supportive Care Needs and Their Attitudes Toward Complementary and Alternative Medicine

BACKGROUND

Cancer patients have high supportive care needs related to the nature of the disease and treatment methods. To meet these needs or reduce symptoms, patients can be expected to resort to alternative treatment methods.

AIM

To examine the relationship between the supportive care needs of cancer patients and their attitudes toward complementary and alternative medicine (CAM).

METHODS

This was a cross-sectional study involving 289 cancer patients at the Oncology Hospital in east of Turkey. Short-Form Supportive Care Needs Survey Questionnaire (SCNS-SF 29) and Holistic Complementary and Alternative Medicine Questionnaire (HCAMQ) were standard instruments used for data collection. The association between supportive care needs and attitude toward CAM was determined.

RESULTS

The mean age of the study participants was 56.7 ± 12.7 years. There were 180 females (62.3%) and 109 males (37.7%). The mean score of the SCNS-SF 29 of the study participant was 101.19 ± 33.97. It was found that the patients' psychological needs were the highest, followed by health services and information, daily life, and sexuality needs, respectively. The mean score of the HCAMQ was 27.16 ± 9.54. There was a weak, significant negative correlation between HCAM and psychological supportive care needs (r: -0.240, P: 0.003). However, there was no significant relationship between needs related to health services information, daily life sexuality, and attitudes toward CAM.

CONCLUSIONS

Cancer patients have high supportive care requirements. Those with high psychological needs have a positive attitude toward HCAM. Incorporation of HCAM in the care of cancer patients may improve their quality of care.

Effects of COVID-19 fear and anxiety on attitudes towards complementary and alternative medicine use in women with gynecological cancer during the COVID-19 pandemic

OBJECTIVE

Patients with gynecological cancer commonly use complementary and alternative medicine (CAM) methods to cope with the disease. However, despite the existence of treatment strategies, the effect of fear and anxiety caused by coronavirus disease 2019 (COVID-19) pandemic on attitudes about CAM use is unclear. This study was carried out to investigate the effect of fear and anxiety experienced by patients with gynecological cancer during the COVID-19 pandemic on their attitudes towards the use of CAM.

METHODS

This is a cross-sectional and descriptive study that included 177 women with gynecological cancer; participants were recruited from a social networking site for cancer patients in Turkey between June and December 2021. Data were collected using an online survey that included the Personal Information Form, the Fear of COVID-19 Scale, the Coronavirus Anxiety Scale, and the Attitude Towards Holistic Complementary and Alternative Medicine Scale. Descriptive statistics, t-test, Pearson's correlation test, and simple linear and multiple regression analyses were performed to analyze the data.

RESULTS

During the pandemic, 55.4% of the participants reported using CAM methods, but only 22.6% were using CAM before the pandemic. The participants who used CAM during the pandemic also scored higher on the fear of COVID-19 and coronavirus anxiety scales (20.69 ± 5.37 and 13.09 ± 6.29, respectively) compared to the participants who did not use CAM (9.29 ± 2.72 and 6.35 ± 2.06, respectively). Fear of COVID-19 accounted for 52% of the CAM attitude score, while coronavirus anxiety accounted for 15% of the CAM attitude score. Fear of COVID-19 and coronavirus anxiety together accounted for 53% of CAM attitude.

CONCLUSION

Gynecological cancer patients with high levels of COVID-19-related anxiety and fear during the pandemic used CAM more. Given that the psychological effects of the pandemic will continue in the coming years, CAM use should be evaluated as a coping strategy, especially due to the COVID-19-related anxiety and fear experienced by patients with gynecological cancer. While the rational and effective CAM methods should be supported, strategies should be developed to prevent misuse of CAM and its interference in prescribed medical treatments.

Alternative and complementary medicine in neurological disorders and neurological disability patients: Prevalence, factors, opinions and reasons

OBJECTIVES

This cross-sectional study is aimed to investigate the prevalence of the use of complementary and alternative medicine (CAM), types of CAMs used, as well as reasons and factors found in patients with neurological diseases or neurological disability.

METHODS

An anonymous, self-administered survey was designed to collect information about demographics, personal medical history, CAM usage habits, and different opinions about CAM vs. conventional medicine (CM). The survey was applied by non-medical personnel in a rehabilitation hospital to patients older than 18 years, with a confirmed diagnosis of neurological disorder or neurological disability.

RESULTS

453 patients were included, 59.7 % were female. Mean age: 49 years (SD: 18.2). 200 patients (44.2 %) had a history of chronic diseases. Depression was found in 139 patients (30.7 %). Neurological disorders were: peripheral neuropathy: 97 (21.4 %), headache or migraine: 78 (17.2 %), neurodegenerative diseases: 69 (15.2 %) and stroke: 58 (12.8 %). 60.2 % (n = 273) had some degree of disability. Prevalence of CAM use was 36 % (n = 163). Most common CAMs were: Biological therapies: 133 (71.1 %), energy-based therapies: 63 (33.7 %) and body manipulation therapies: 51 (27.3 %). Reasons to use CAM were: "to complement the pharmacological treatment" (45 = 27.6 %), and "treatment failure with CM" (43 = 26.4 %). Finally, older age (p = 0.0280) and having a chronic disease (p = 0.0229) or depression (p < 0.001) were the factors associated with the current use of CAM.

CONCLUSION

One third of patients with neurological pathologies use CAM, the most popular type of CAM is biologic therapies. As in other pathologies, CAM use was associated with older age, history of depression, and chronic diseases. Therefore, it is suggested that physicians routinely ask patients about the use of CAM, if they need more information about CAM, and even verify the possibility of drug interactions or adverse effects.

Use of Complementary and Alternative Medicine (CAM) in Patients With Colorectal Cancer

This study was conducted to analyze the relationship between cancer-related stress and the types of complementary and alternative medicine (CAM) used by subjects diagnosed with colorectal cancer. The number of study subjects was 142, and for data analysis, descriptive statistics, t-test, χ2 test, logistic regression procedures were performed. Of the subjects, 114 were CAM users, who accounted for 79.6%. When it came to using CAM, 82 (72.6%) said they did "to prevent cancer recurrence." The most popular reason for not using CAM was "to focus on treatment as instructed by the doctor," with 22 (75.8%) respondents selecting the answer. Of those who used CAM, 79 (55.6%) said they took "dietary supplements," followed by 65 (45.8%) who picked "vitamins and minerals." Regarding CAM usage, ginger, aloe, swimming, and walking had the highest satisfaction (4.25 ± 0.71). The cancer-related stress of subjects who use CAM (18.21 ± 15.37) was higher than that of subjects who did not use CAM (10.11 ± 12.08). Logistic regression analysis determined that cancer-related stress were factors significantly associated with CAM use. Patients using CAM had higher cancer-related stress, suggesting that stress on cancer increased CAM interest. Safe and reliable CAM information and standardized recommendations should be provided to cancer survivors. We propose the development of training programs for CAM to improve communication between medical staff and patients and to protect patients.

The effect of cancer on traditional, complementary and alternative medicine utilization in Korea: a fixed effect analysis using Korea Health Panel data

BACKGROUND

Cancer-related incidence and mortality rates are rapidly increasing worldwide. However, no studies have examined the effect of cancer as a single factor on the use of traditional, complementary, and alternative medicine (T&CAM). We aimed to determine the effect of cancer occurrence on T&CAM utilization using Korea Health Panel (KHP) data.

METHODS

We analyzed longitudinal data (49,380 observations) derived from 12,975 Korean adult participants with complete KHP data from 2011 to 2014 and 2016, and divided them into two groups based on cancer diagnosis. A panel multinomial logit model was used to assess whether the participants used T&CAM or conventional medicine or both in outpatient settings. Additionally, a negative binomial regression model was used to examine the effect of cancer on the number of outpatient visits for T&CAM.

RESULTS

In total, 25.54% of the study participants in the cancer group used T&CAM, which was higher than that in the non-cancer group (18.37%, p < 0.0001). A panel multinomial logistic regression analysis using KHP data showed that cancer occurrence was significantly more likely to be associated with 'Using both Korean medicine and conventional medicine' (Coef. = 0.80, p = 0.017) and 'Not using Korean medicine but using conventional medicine' (Coef. = 0.85, p = 0.008) than 'Not using Korean medicine and conventional medicine.' A panel negative binomial regression showed a significant effect of cancer on increasing the number of T&CAM outpatient visits (Coef. = 0.11, p = 0.040).

CONCLUSIONS

Our findings showed that cancer occurrence within an individual led to the simultaneous use of conventional medicine and T&CAM. In addition, the occurrence of cancer significantly increased the number of T&CAM outpatient visits among participants already using T&CAM. It was also found that T&CAM has been utilized more often by the most vulnerable people, such as medical beneficiaries and those with a low level of education.

Attitudes and Beliefs of Cancer Patients Demanding Medical Cannabis Use in North Thailand

OBJECTIVE

Cannabis is therapeutic for numerous medical conditions. The demand for medical cannabis (MC) use in cancer patients is increasing, even with many patients lacking proper knowledge about MC. Therefore, this study aimed to describe the attitudes and beliefs of cancer patients demanding MC use in northern Thailand.

METHODS

This cross-sectional study administered multistage random sampling to recruit 565 cancer patients who indicated that they demand MC use in northern Thailand. These patients responded to a self-administered structured questionnaire about their feelings on MC. We used descriptive statistics, including frequency and percentage, to describe categorical data, whereas we used mean and standard deviation for continuous data.

RESULTS

Out of a total of 565 participants, 59.7% were female, 40.3% were male, and 46.4% were middle-aged adults, with a mean age of 58.3 ± 13.0 years. Of these participants who demanded the use of MC, the top three most common types of cancers were breast cancer (27.8%), colorectal cancer (21.4%), and lung cancer (10.6%). Most of the participants (51.2%) had early-stage cancer, and 46.5% received chemotherapy. We found that patients who demanded MC use had a generally positive attitude (53.3%). Among the patients who required MC use, 55.4% believed that it would help relieve side effects caused by modern treatments, cure cancer (38.8%), relieve suffering from cancer symptoms (30.6%), and cause one to live longer and to improve their health (16.3%). Most patients' decisions regarding MC use (45.3%) demanded MC use after receiving modern treatments, and 95.6% demanded MC use with modern treatment. Overall, these patients (65.3%) needed MC from the MC clinic in the Government Hospital.

CONCLUSIONS

This study highlights the attitudes and beliefs towards MC use among cancer patients, their positive expectations of the outcome, and the need for MC use.

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.

The Current Status of Integrative Oncology in Korea

Cancer is one of the leading causes of death worldwide, and Korea is no exception. Humanity has been fighting cancer for many years, and as a result, we now have effective treatments such as chemotherapy, radiation, and surgery. However, there are other issues that we are only now beginning to address, such as cancer patients’ quality of life. Moreover, numerous studies show that addressing these issues holistically is critical for overall cancer treatment and survival rates. This paper describes how Korea is attempting to reduce cancer incidence and recurrence rates while also managing the quality of life of cancer patients. Integrative Oncology is the field that addresses these broad issues, and understanding the current state of integrative oncology in Korea is critical. The goal of this paper is to provide an overview of the current state of integrative oncology in Korea as well as to look ahead to future developments.

Use of Complementary and Alternative Medicine for Prostate Cancer among African Americans, African Immigrants and Caribbean Immigrants

Black men have the highest rate of prostate cancer (PCa) morbidity and mortality in the US, and often receive delayed and/or poorer-quality treatment. This inequity has led many to turn to complementary and alternative medicine/therapies (CAM). However, little is known about the use of these therapies within the Black community. The purpose of this study was to describe types of CAM therapies used, and the reasons behind their use for overall health and PCa treatment and prevention among three groups of Black males, namely African Americans, Caribbean Immigrants and African Immigrants. This study used a mixed-methods design with a quantitative phase (n = 575) followed by a qualitative phase (n = 61) with participants recruited from various parts of the country. Results revealed differences among subgroups in CAM use for overall health and PCa, as well as differences in the types of CAM therapies used and differences in the reasons behind their use. The findings of this study reveal a prevalence of CAM use for overall health and PCa within three different groups of Black men and identifies the specific CAM used. There were significant differences in the types of CAM used by each subgroup for both overall health and PCa. This study also shows that there is value in looking at Black subgroups distinctively, for their rates of CAM use and reasons for use, are distinctly different.

Efficacy of Chemotherapy Integrated With Traditional Korean Medicine in Patients With Metastatic Pancreatic Cancer: A Single-Center Retrospective Study

Background:

This retrospective study investigated the efficacy and safety of chemotherapy (CTX) integrated with Traditional Korean Medicine (TKM) in patients with metastatic pancreatic cancer, in a single Korean center.

Methods:

From January, 2014 to February, 2019, patients with metastatic pancreatic cancer who had received CTX were enrolled. Overall survival (OS), demographic characteristics, and adverse events were examined. Statistical analysis was utilized to evaluate the differences in characteristics and to compare the survival rates between the CTX group and CTX+TKM group. Kaplan-Meier curves were used to compare the differences in survival time. A Cox regression analysis was performed to determine the hazard ratio of the risk of mortality.

Results:

A total 37 participants were included and visited a TKM hospital 7.4 ± 8.3 months after being diagnosed with metastatic pancreatic cancer. The median age of the participants was 62 years; 26 patients (70.3%) had an Eastern Cooperative Oncology Group (ECOG) performance status between 0 and 2, and 23 patients (62.2 %) had first-line CTX failure. The median OS of all patients was 3.8 months (95% CI, 3.1-4.6). The CTX + TKM group showed longer survival (4.1 months; 95% CI, 2.4- .8) than the CTX group (2.4 months, 95% CI 0.2-4.6) but this was not statistically significant (P = .217). Chemotherapy with TKM treatment for more than 30 days (CTX + TKM ≥ 30) significantly prolonged median OS (9.1 months; 95% CI, 3.6-14.5; P = .025) compared to chemotherapy alone. Cox hazard ratio analysis revealed that CTX + TKM ≥ 30 and prior chemotherapy were significantly independent prognostic factors for OS. The main herbs in the TKM treatment were Rhus verniciflua Stokes and Astragalus. Severe adverse events with respect to TKM treatment were not reported.

Conclusions:

TKM treatment integrated with chemotherapy may prolong OS in patients with metastatic pancreatic cancer compared to chemotherapy treatment alone. More rigorous prospective clinical trials are needed to confirm this result.

Biologically-Based Complementary and Alternative Medicine (CAM) Use in Cancer Patients: The Good, the Bad, the Misunderstood

As complementary and alternative medicine (CAM) becomes more popular, it is being used in cancer patients to aid in recovery or to treat symptoms associated with the current chemotherapy. Numerous papers exist that discuss patients using CAM with cancer chemotherapy and their outcomes-both positive and negative. However, in the case of the negative outcomes, the reason for the dangers or interactions with drugs are not made clear. Indeed, many chemotherapy regimens are rendered less effective by the well-meaning but uninformed patient or their family members and friends. Similarly, reports of positive outcomes with CAM and chemotherapy provide a strong basis for further research, but do not identify specific mechanisms of action. These small clinical studies and in vitro studies identify a necessary area for further research and provide a much needed, although often rejected, alternative look at whole treatment plans. Careful review of the available information and evaluation of the nature of the CAM effects are necessary to combat the misunderstanding and sometimes unwarranted claims over CAM use. This mini review will explore some of the commonly used CAM agents and their mechanisms of interactions with other treatments. Suggestions as to which agents can be safe and when to use them will be an integral part of this review.
