Alternative therapies used by women with breast cancer in four ethnic populations

Traditional Chinese medicine use among Chinese immigrant cancer patients

Traditional Chinese Medicine (TCM) includes both herbal remedies and non-herbal practices. Chinese cancer patients are particularly at high risk for herb-drug interactions. Providers, both primary care physicians and oncologists, frequently do not ask patients about TCM use, which has potentially dangerous consequences. This study describes an assessment of TCM use while undergoing conventional cancer treatment, among a cohort of Chinese immigrant cancer patients in New York City. The Immigrant Health and Cancer Disparities Service at Memorial Sloan-Kettering Cancer Center assists underserved cancer patients through a patient navigation program, the Cancer Portal Project. Six questions related to TCM are included in the existing Portal Needs Assessment Intake. Mandarin- or Cantonese-speaking Portal patients enrolled between January 2010 and May 2012 were surveyed. One hundred nine Chinese-speaking patients were enrolled in the Portal Project during the study period. Forty-six completed the TCM questions. Ninety-six percent preferred to speak Mandarin, Cantonese, or Fujianese in the healthcare setting. Thirty-nine percent (n = 18) of the 46 participants reported using TCM since being diagnosed with cancer. Nearly all (n = 16) who used TCM reported using herbal medicines. Ten TCM users did not describe sharing their use with Western doctors. Eight (44%) of TCM users reported concurrently using TCM and conventional cancer treatment. Larger scale studies should further explore the concurrent use of TCM and conventional cancer treatment in this unique population. Future research should also address patient-provider communication related to the concurrent use of TCM and cancer treatment. This is also an important area of education for both patients and providers.

Attitudes and barriers towards participation in an acupuncture trial among breast cancer patients: a survey study

Background

As breast cancer patients increasingly use complementary and alternative medicine (CAM), clinical trials are needed to guide appropriate clinical use. We sought to identify socio-demographic, clinical and psychological factors related to willingness to participate (WTP) and to determine barriers to participation in an acupuncture clinical trial among breast cancer patients.

Methods

We conducted a cross-sectional survey study among post-menopausal women with stage I-III breast cancer on aromatase inhibitors at an urban academic cancer center.

Results

Of the 300 participants (92% response rate), 148 (49.8%) reported WTP in an acupuncture clinical trial. Higher education (p = 0.001), increased acupuncture expectancy (p < 0.001), and previous radiation therapy (p = 0.004) were significantly associated with WTP. Travel difficulty (p = 0.002), concern with experimentation (p = 0.013), and lack of interest in acupuncture (p < 0.001) were significant barriers to WTP. Barriers differed significantly by socio-demographic factors with white people more likely to endorse travel difficulty (p = 0.018) and non-white people more likely to report concern with experimentation (p = 0.024). Older patients and those with lower education were more likely to report concern with experimentation and lack of interest in acupuncture (p < 0.05).

Conclusions

Although nearly half of the respondents reported WTP, significant barriers to participation exist and differ among subgroups. Research addressing these barriers is needed to ensure effective accrual and improve the representation of individuals from diverse backgrounds.

Biologically based therapies are commonly self-prescribed by Brazilian women for the treatment of advanced breast cancer or its symptoms

PURPOSE

Breast cancer (BC) might be associated with loss of function in affected patients, with a direct impact on their quality of life (QOL). Many women with metastatic BC seek relief of symptoms, including the use of complementary and alternative medicine (CAM) to cure cancer. The present study aimed to identify the pattern of CAM used by patients with metastatic BC and to assess the correlation between CAM use and scores on anxiety, depression, and QOL scales.

METHODS

A total of 126 women with metastatic BC were interviewed using four instruments: (1) a questionnaire containing socioeconomic, clinical, and demographic data and CAM use; (2) European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ)-C30; (3) EORTC QLQ-BR23; and (4) the Hospital Anxiety and Depression Scale.

RESULTS

Fifty percent of the participants reported the use of at least one CAM modality. Biologically based practices were the most frequently used to treat BC and/or its symptoms, the most commonly discussed with the oncologists, and one of the CAM categories in which more patients reported a desire to learn more about. The overall use of CAM was not correlated with the scores on the anxiety, depression, and QOL scales. However, analysis of the association of the QOL scores with specific CAM modalities revealed some potential associations (especially for food supplements, art therapy, psychotherapy, and prayer).

CONCLUSIONS

Women with metastatic BC frequently make use of CAM to treat the cancer and/or its symptoms. Biologically based practices seem to be particularly important in Brazil. An association between specific CAM modalities and some QOL domains was suggested, but it needs further confirmation.

Reasons to Use and Disclose Use of Complementary Medicine Use - An Insight from Cancer Patients

Studies have shown a high prevalence (40–83%) of complementary and alternative medicine (CAM) use among cancer patients in the U.S.A cross-sectional, mixed-methods pilot study was completed. This paper focuses on the quantitative analysis conducted on demographic predictors of complementary medicine (CM) use, reasons to use CM, and disclosure to healthcare provider data. Surveys were interview-administered at the Loma Linda University Medical Center Cancer Center. Participants, 18 years or older, were selected from a convenient sample. Eighty-seven percent (87.9%) of participants reported to have used CM as a cancer treatment and most reported to have used it “to help fight the cancer.” Women were eight-times more likely to use prayer. All non-Caucasian and Hispanic participants reported to use CM as a cancer therapy and none reported to use a CM provider. More women (72%) disclosed their CM use than men (53.3%). Different prevalences and predictors exist when differentiating CM modalities, reasons to use CM vary by gender, and disclosure proportions vary by gender.

Use of Self-Care and Practitioner-Based Forms of Complementary and Alternative Medicine before and after a Diagnosis of Breast Cancer

Purpose. We examine factors associated with self-care, use of practitioner-based complementary and alternative medicine (CAM), and their timing in a cohort of women with breast cancer. Methods. Study participants were women with breast cancer who participated in the Long Island Breast Cancer Study Project. Self-care is defined as the use of multivitamins, single vitamins, botanicals, other dietary supplements, mind-body practices, special diets, support groups, and prayer. Within each modality, study participants were categorized as continuous users (before and after diagnosis), starters (only after diagnosis), quitters (only before diagnosis), or never users. Multivariable logistic regression was used for the main analyses. Results. Of 764 women who provided complete data, 513 (67.2%) initiated a new form of self-care following breast cancer diagnosis. The most popular modalities were those that are ingestible, and they were commonly used in combination. The strongest predictor of continuous use of one type of self-care was continuous use of other types of self-care. Healthy behaviors, including high fruit/vegetable intake and exercise, were more strongly associated with continuously using self-care than starting self-care after diagnosis. Conclusions. Breast cancer diagnosis was associated with subsequent behavioral changes, and the majority of women undertook new forms of self-care after diagnosis. Few women discontinued use of modalities they used prior to diagnosis.

Do spiritual patients want spiritual interventions?: A qualitative exploration of underserved cancer patients' perspectives on religion and spirituality

OBJECTIVE

This study examines religion and spirituality among advanced cancer patients from an underserved, ethnically-diverse population by exploring patient conceptualizations of religion and spirituality, the role of religion and spirituality in coping with cancer, and patient interest in spiritual support.

METHOD

Qualitative semi-structured interviews were conducted with patients who had participated in a study of a "mind-body" support group for patients with all cancer types. Analysis based on grounded theory was utilized to identify themes and theoretical constructs.

RESULTS

With regard to patient conceptualizations of religion and spirituality, three categories emerged: (1) Spirituality is intertwined with organized religion; (2) Religion is one manifestation of the broader construct of spirituality; (3) Religion and spirituality are completely independent, with spirituality being desirable and religion not. Religion and spirituality played a central role in patients' coping with cancer, providing comfort, hope, and meaning. Patients diverged when it came to spiritual support, with some enthusiastic about interventions incorporating their spiritual values and others stating that they already get this support through religious communities.

SIGNIFICANCE OF RESULTS

Spirituality plays a central role in the cancer experience of this underserved ethnically-diverse population. While spirituality seems to be a universal concern in advanced cancer patients, the meaning of spirituality differs across individuals, with some equating it with organized religion and others taking a more individualized approach. It is important that psychosocial interventions are developed to address this concern. Future research is needed to further explore the different ways that patients conceptualize spirituality and to develop spiritually-based treatments that are not "one size fits all."

Knowledge and perceptions of cancer and cancer prevention among Malaysian traditional healers: a qualitative study

OBJECTIVE

The objective of this study was to explore the knowledge and perceptions of Malaysian tradition healers towards cancer and cancer prevention.

METHODOLOGY

A total of 25 participants agreed to participate in this qualitative study during the period from 20th July 2011 until 24th of September 2011. The proposal of this study was approved by the Ethics Committee of Management and Science University (MSU). Once the participant agreed to be interviewed, date, time and place of the interviews were determined. Consent form was obtained from participants before the interview began. Participants were briefed about the study and its purpose, and after asking their permission, their replies were recorded. The data was organized into themes and analyzed manually.

RESULTS

Twenty-five Malaysian traditional healers participated in this qualitative study. The age of participants ranged between 26 to 78 years old. The majority were in the age group of 31-60 years old, male, Chinese, degree holders with a monthly income ranging from 1,000-5,000 Ringgit Malaysia (RM) and were married (56%, 80%, 48%, 52%, 68%, 84% respectively). The majority defined cancer as having high cholesterol or abscess accumulation. A few of them defined cancer as a type of cell growth. The majority mentioned that food and unhealthy lifestyles are the primary causes of cancer. Surprisingly some of them mentioned that cancer is caused by interference by ghosts. Regarding the diagnosis of cancer, the majority mentioned that they refer their patients to modern physicians' medical report when it comes to diagnosing or treating patients with cancer. The most common cancers that many patients came to seek treatment were breast cancers, followed by colon cancers, liver and lung cancers.

CONCLUSION

Despite good knowledge about the causes of cancer among traditional healers, misconceptions still exist. Insufficient knowledge about the definition of cancer was noted among the traditional healers. This urges immediate action by the Ministry of Health of Malaysia to set up a strict regulation and regular monitoring of the traditional healers nationally. Traditional and Complementary Medicine may be integrated into the healthcare system and need to have sustained cooperation for the benefit of patients since about 80% of patients use traditional medicines.

Complementary and Alternative Medicine Use among Norwegian Cancer Survivors: Gender-Specific Prevalence and Associations for Use

The associations for CAM use are only occasionally differentiated by gender in populations where both male and female cancer survivors occur. The aim of this study is to describe the prevalence of CAM use in individuals with a previous cancer diagnosis and to investigate gender differences regard to factors associated with use. A total of 12982 men and women filled in a questionnaire with questions about life style and health issues. Eight hundred of those had a previous cancer diagnosis of whom 630 answered three questions concerning CAM use in the last 12 months. A total of 33.8% of all cancer survivors reported CAM use, 39.4% of the women and 27.9% of the men (P < 0.01). The relationship between the demographic variables and being a CAM user differed significantly between men and women with regard to age (P = 0.03), education (P = 0.04), and income (P < 0.01). Female CAM users were more likely to have a university degree than the nonusers, while male CAM users were more likely to have a lower income than the nonusers. According to this study, prevalence and factors associated with CAM use differ significantly between male and female survivors of cancer.

Initial evidence of religious practice and belief in depressed african american cancer patients

Objective:

This study examined spiritual coping (beliefs and practices) of depressed African American cancer patients through a comparison with depressed White cancer patients and non-depressed African American cancer patients.

Methods:

Using mixed methods, 74 breast (n=41) and prostate (n=33) cancer survivors including 34 depressed and 23 nondepressed African Americans and 17 depressed Whites were interviewed. The interviews were audiotaped and transcribed. Qualitative data analysis identified themes that were coded. The codes were entered into SPSS software. The Fisher’s exact test was performed to examine group differences in self-reported spiritual coping.

Results:

Significantly more depressed African Americans questioned God when learning of a cancer diagnosis than the non-depressed African Americans (p=.03), but they did not differ from the depressed Whites in this regard (p=.70). Significantly more depressed African Americans reported having faith in God (p=.04), reading the bible (p=.02), and conversing with God (p=.01) than did the depressed Whites. They also reported praying alone (p=.01) more frequently than the depressed Whites who, on the other hand, reported praying with others (non-family members) together for one’s own health more frequently (p=.04).

Conclusions:

Depression is associated with a deepening need for spirituality and it affects religious beliefs and practices more in African American than White cancer patients. Given its important role in the lives of African American cancer patients, spirituality may be utilized as a reasonable, culturally-based approach to better assess and treat depression in these patients.

Complementary and alternative medicine use and breast cancer prognosis: a pooled analysis of four population-based studies of breast cancer survivors

BACKGROUND

Complementary and alternative medicine (CAM) use is common among breast cancer survivors, but little is known about its impact on survival.

METHODS

We pooled data from four studies conducted in Hawaii in 1994-2003 and linked to the Hawaii Tumor Registry to obtain long-term follow-up information. The effect of CAM use on the risk of breast cancer-specific death was evaluated using Cox regression.

RESULTS

The analysis included 1443 women with a median follow-up of 11.8 years who had a primary diagnosis of in situ and invasive breast cancer. The majority were Japanese American (36.4%), followed by white (26.9%), Native Hawaiian (15.9%), other (10.6%), and Filipino (10.3%). CAM use was highest in Native Hawaiians (60.7%) and lowest in Japanese American (47.8%) women. Overall, any use of CAM was not associated with the risk of breast cancer-specific death (hazard ratio [HR] 1.47, confidence interval [CI] 0.91-2.36) or all-cause death (HR 0.82, 95% CI 0.63-1.06). However, energy medicine was associated with an increased risk of breast cancer-specific death (HR 3.19, 95% CI 1.06-8.52). When evaluating CAM use within ethnic subgroups, Filipino women who used CAM were at increased risk of breast cancer death (HR 6.84, 95% CI 1.23-38.19).

CONCLUSIONS

Our findings suggest that, overall, CAM is not associated with breast cancer-specific death but that the effects of specific CAM modalities and possible differences by ethnicity should be considered in future studies.

Utilization of and Attitudes towards Traditional Chinese Medicine Therapies in a Chinese Cancer Hospital: A Survey of Patients and Physicians

Background. In China, the use of traditional Chinese medicine (TCM) is very popular, but little is known about how it is integrated with conventional cancer care. We conducted parallel surveys of patients and physicians on TCM utilization. Methods. Two hundred forty-five patients and 72 allopathic physicians at the Fudan University Shanghai Cancer Center completed questions on their use of and attitude towards TCM. Results. Patient mean age was 51, with 60% female. Eighty-three percent of patients had used TCM. Use was greatest for Chinese herbal medicine (CHM; 55.8%). Only 1.3% of patients used acupuncture and 6.8% Qi Gong or Tai Qi. Sixty-three percent of patients notified their oncologist about TCM use. The most common reason for use was to improve immune function. CHM was often used with a goal of treating cancer (66.4%), a use that 57% of physicians agreed with. Physicians were most concerned with interference with treatment, lack of evidence, and safety. Ninety percent of physicians have prescribed herbs and 87.5% have used TCM themselves. Conclusion. The use of TCM by Chinese cancer patients is exceptionally high, and physicians are generally well informed and supportive of patients' use. Botanical agents are much more commonly used than acupuncture or movement-based therapies.

Effects of yoga on psychologic function and quality of life in women with breast cancer: a meta-analysis of randomized controlled trials

OBJECTIVE

The aim of this meta-analysis was to evaluate the effects of yoga on psychologic function and quality of life (QoL) in women with breast cancer.

DESIGN

A systematic search of PubMed, EMBASE, the Cochrane Library, the Chinese Biomedical Literature Database, and the Chinese Digital Journals Full-text Database was carried out. Randomized control trials (RCTs) examining the effects of yoga, versus a control group receiving no intervention, on psychologic functioning and QoL in women with breast cancer were included. Methodological quality of included RCTs was assessed according to the Cochrane Handbook for Systematic Reviews of Interventions 5.0.1, and data were analyzed using the Cochrane Collaboration's Review Manager 5.1.

RESULTS

Six (6) studies involving 382 patients were included. The meta-analysis showed that yoga can improve QoL for women with breast cancer. A statistically significant effect favoring yoga for the outcome of QoL was found (standard mean difference=0.27, 95% confidence interval [0.02, 0.52], p=0.03). Although the effects of yoga on psychologic function outcomes--such as anxiety, depression, distress and sleep--were in the expected direction, these effects were not statistically significant (p>0.05). Fatigue showed no significant difference (p>0.05).

CONCLUSIONS

The present data provided little indication of how effective yoga might be when they were applied by women with breast cancer except for mildly effective in QOL improvement. The findings were based on a small body of evidence in which methodological quality was not high. Further well-designed RCTs with large sample size are needed to clarify the utility of yoga practice for this population.

Predictors of Use of Complementary and Alternative Medicine by Non-Hodgkin Lymphoma Survivors and Relationship to Quality of Life

Hypotheses. This study hypothesized that non-Hodgkin lymphoma (NHL) patients who used complementary and alternative medicine (CAM) would have higher health-related quality of life (HRQOL) and a greater perceived sense of control than nonusers. However, since CAM may predict HRQOL, and perceived control may be both associated with CAM use as well as being an independent predictor of HRQOL, the authors also sought to test whether perceived control mediated the relationship between CAM use and HRQOL. Study design. This was a cross-sectional study design. NHL survivors diagnosed between June 1, 1998 and August 31, 2001 were selected from the population-based SEER (Surveillance, Epidemiology, and End Results) cancer registry for Los Angeles County and were mailed a survey in 2003 that assessed CAM use and predictors of CAM use. The response rate was 54.8%; 319 provided complete data for analysis. Methods. Categories of CAM were defined according to the National Center for Complementary and Alternative Medicine guidelines. The authors measured survivors’ cancer-related control using the Perceived Personal Control scale, a 4-question scale that was adapted from previously validated scales. HRQOL was measured using the mental component summary and physical component summary scores from the SF-36 v2.0. Bivariate and multivariable logistic and linear regression models were used to assess factors associated with CAM use and the association of CAM use with psychosocial health outcomes, respectively. Results. Sixty-one percent of respondents reported using at least one CAM modality within the past 4 weeks, and 40% did so after excluding personal prayer and support groups. Younger age and higher education were significantly associated with greater CAM use as were higher perception of cancer-related control ( P = .004) and more positive mental functioning ( P = .016). Perception of control significantly mediated the association between CAM use and mental functioning ( P < .001). Conclusions. CAM use may be related to more positive mental health–related quality of life by increasing patients’ perception of perceived control over their health; however, cause and effect cannot be determined. Physicians should be aware that cancer survivors have a need to take an active role in improving their health.

A prospective, multicenter study of complementary/alternative medicine (CAM) utilization during definitive radiation for breast cancer

PURPOSE

Although complementary and alternative medicine (CAM) utilization in breast cancer patients is reported to be high, there are few data on CAM practices in breast patients specifically during radiation. This prospective, multi-institutional study was conducted to define CAM utilization in breast cancer during definitive radiation.

MATERIALS/METHODS

A validated CAM instrument with a self-skin assessment was administered to 360 Stage 0-III breast cancer patients from 5 centers during the last week of radiation. All data were analyzed to detect significant differences between users/nonusers.

RESULTS

CAM usage was reported in 54% of the study cohort (n=194/360). Of CAM users, 71% reported activity-based CAM (eg, Reiki, meditation), 26% topical CAM, and 45% oral CAM. Only 16% received advice/counseling from naturopathic/homeopathic/medical professionals before initiating CAM. CAM use significantly correlated with higher education level (P<.001), inversely correlated with concomitant hormone/radiation therapy use (P=.010), with a trend toward greater use in younger patients (P=.066). On multivariate analysis, level of education (OR: 6.821, 95% CI: 2.307-20.168, P<.001) and hormones/radiation therapy (OR: 0.573, 95% CI: 0.347-0.949, P=.031) independently predicted for CAM use. Significantly lower skin toxicity scores were reported in CAM users vs nonusers, respectively (mild: 34% vs 25%, severe: 17% vs 29%, P=.017).

CONCLUSION

This is the first prospective study to assess CAM practices in breast patients during radiation, with definition of these practices as the first step for future investigation of CAM/radiation interactions. These results should alert radiation oncologists that a large percentage of breast cancer patients use CAM during radiation without disclosure or consideration for potential interactions, and should encourage increased awareness, communication, and documentation of CAM practices in patients undergoing radiation treatment for breast cancer.

Development and Validation of an Instrument for Measuring Attitudes and Beliefs about Complementary and Alternative Medicine (CAM) Use among Cancer Patients

Despite cancer patients' extensive use of complementary and alternative medicine (CAM), validated instruments to measure attitudes, and beliefs predictive of CAM use are lacking. We aimed at developing and validating an instrument, attitudes and beliefs about CAM (ABCAM). The 15-item instrument was developed using the theory of planned behavior (TPB) as a framework. The literature review, qualitative interviews, expert content review, and cognitive interviews were used to develop the instrument, which was then administered to 317 outpatient oncology patients. The ABCAM was best represented as a 3-factor structure: expected benefits, perceived barriers, and subjective norms related to CAM use by cancer patients. These domains had Eigenvalues of 4.79, 2.37, and 1.43, and together explained over 57.2% of the variance. The 4-item expected benefits, 7-item perceived barriers, and 4-item subjective norms domain scores, each had an acceptable internal consistency (Cronbach's alpha) of 0.91, 0.76, and 0.75, respectively. As expected, CAM users had higher expected benefits, lower perceived barriers, and more positive subjective norms (all P < 0.001) than those who did not use CAM. Our study provides the initial evidence that the ABCAM instrument produced reliable and valid scores that measured attitudes and beliefs related to CAM use among cancer patients.

Physical distress and cancer care experiences among Chinese-American and non-Hispanic White breast cancer survivors

OBJECTIVE

The number of Chinese-American breast cancer survivors (BCS) is increasing as a result of increasing incidence rates. There has been little research on Chinese BCS' follow-up cancer care. This qualitative study aims to understand how Chinese-American BCS experience and cope with physical distress relative to non-Hispanic White (NHW) survivors.

METHODS

Seventy-one BCS (37 Chinese immigrant, 7 US-born Chinese, 27 NHW) were recruited from the Greater Bay Area Cancer Registry to participate in focus group discussions or one-on-one interviews about their survivorship experiences. All BCS were diagnosed with breast cancer at stage 0-IIA between 2006 and 2009, and had survived for 1-4 years without recurrence. Interviews were conducted in Cantonese, Mandarin, or English. Data analyses followed established qualitative methods of content analysis.

RESULTS

BCS experienced pain and side effects from radiation, surgery, and hormonal therapy. Physical distress subsequently caused emotional concerns about recurrence or metastasis. Most BCS consulted physicians about their physical distress. Chinese immigrant BCS were less likely to have their issues resolved compared to NHW and US-born Chinese who were more likely to question physicians, ask for referrals, and make repeat attempts if their problems were not resolved. Some Chinese immigrant BCS turned to Traditional Chinese Medicine for relief or accepted the idea that physical distress was part of survivorship.

CONCLUSION

Chinese immigrant BCS may be at risk for greater distress compared with US-born Chinese and NHW BCS because of cultural norms that make them less inclined to express their needs to physicians or challenge physicians when their needs are not met. Furthermore, they may express symptoms in culturally unique ways (e.g., hot-cold imbalances). Further research is needed to determine how to best improve survivorship care experiences in this understudied population, with the goal of decreasing BCS' physical distress and improving quality of life.

Use of complementary medications among older adults with cancer

BACKGROUND

Little is known about complementary medication use among older adults with cancer, particularly those who are receiving chemotherapy. The objective of this study was to evaluate the prevalence of complementary medication use and to identify the factors associated with its use among older adults with cancer.

METHODS

The prevalence of complementary medication use (defined as herbal agents, minerals, or other dietary supplements, excluding vitamins) was evaluated in a cohort of adults aged ≥65 years who were about to start chemotherapy for their cancer. The associations between complementary medication use and patient characteristics (sociodemographics; comorbidities; and functional, nutritional, psychological, and cognitive status), medication use (number of medications and concurrent vitamin use), and cancer characteristics (type and stage) were analyzed.

RESULTS

The cohort included 545 patients (mean age, 73 years; range, 65-91 years; 52% women) with cancer (61% stage IV). Seventeen percent of these patients (N = 93) reported using ≥1 complementary medication; the mean number of complementary medications among users was 2 (range, 1-10 medications). Complementary medication use was associated with 1) earlier cancer stage (29% had stage I-II disease vs 17% with stage III-IV disease; odds ratio [OR], 2.05; 95% confidence interval [CI], 1.21-3.49) and 2) less impairment with instrumental activities of daily living (OR, 1.39; 95% CI, 1.12-1.73).

CONCLUSIONS

Complementary medication use was reported by 17% of older adults with cancer and was more common among those who had less advanced disease (i.e., those receiving adjuvant, potentially curative treatment) and higher functional status. Further studies are needed to determine the association between complementary medication use and cancer outcomes among older adults.

Practices, attitudes, and beliefs associated with complementary and alternative medicine (CAM) use among cancer patients

INTRODUCTION

The high prevalence of complementary and alternative medicine (CAM) use among cancer patients (40%-83%) receiving conventional treatment and the complex relationship between the psychosocial factors that may contribute to or result from CAM use requires further understanding. The authors conducted a descriptive mixed-methods pilot study to understand CAM practices, attitudes, and beliefs among cancer patients at the Loma Linda University Medical Center.

METHODS

This was the qualitative phase of the study, and no hypotheses were set. A total of 23 face-to-face interviews were conducted, and thematic coding was used to analyze 22 interview transcriptions. There were 14 CAM users (64%) and 8 nonusers (36%).

FINDINGS

The themes present among those who used CAM were the following: physicians viewed as one aspect of health care options, a holistic view on well-being, satisfaction with CAM use, and 3 key coping methods (confrontive, supportive, and optimistic) to confront cancer. Themes were not independent of each other. Two themes were present among nonusers; nonusers trusted their physician and were more likely to express evasive coping methods.

DISCUSSION

Perceptions and behavioral patterns are complex predictors of CAM use. A better understanding of CAM, medical pluralism, and the perceptions of patients would help health care providers deliver a better quality of care. The promotion of integrative care may help health care providers better identify medical pluralism and would shift focus to patient-centered care.

Changes in herb and dietary supplement use in the U.S. adult population: a comparison of the 2002 and 2007 National Health Interview Surveys

BACKGROUND

Past national surveys indicate that use of herbs and dietary supplements rose rapidly in the United States during the 1990s and early 2000s. Additional research is needed to determine whether this growth rate and associated patterns of use have persisted over time.

OBJECTIVES

The objectives of this study were: (1) to assess population and subpopulation changes in rates of herb and supplement use; and (2) to assess changes in rates of disclosure of herb and supplement use to conventional medical providers.

METHODS

This study used data from the 2002 (n = 30,427) and 2007 (n = 22,657) Adult Complementary and Alternative Medicine File to the National Health Interview Survey (NHIS). Weighted group and subgroup comparisons used the Wald χ(2) tests to compare differences in herb and supplement use between 2002 and 2007.

RESULTS

The number of adults in the United States that ever used herbs or supplements grew slightly, from 50.6 million in 2002 to 55.1 million in 2007. However, the proportion of adults who reported use of herbs or supplements in the past 12 months dropped significantly: from 18.9% in 2002 to 17.9% in 2007 (P < 0.05). Subpopulation comparisons revealed that younger adults were less likely to use herbs and supplements in 2007 (17.6%) than in 2002 (20.0%), whereas older adults (ie, those aged ≥65 years) were more likely to do so (19.5% in 2007 vs. 13.2% in 2002). Racial and ethnic minorities also reported a significant decline in recent use. The proportion of respondents that disclosed herb or supplement use to their physician or another conventional medical professional rose, from 33.4% in 2002 to 45.4% in 2007. However, <1% of recent herb and supplement users disclosed this use to their pharmacist. Limitations of this research are that the 2 national data sets were not directly comparable and that questionnaires in the 2 surveys assessed were not identical.

CONCLUSIONS

Herbal preparations and dietary supplements remain popular in the United States, but the user population and patterns of use are changing. Ongoing surveillance of this health behavior is a public health priority.

How many cancer patients use complementary and alternative medicine: a systematic review and metaanalysis

BACKGROUND

No comprehensive systematic review has been published since 1998 about the frequency with which cancer patients use complementary and alternative medicine (CAM).

METHODS

MEDLINE, AMED, and Embase databases were searched for surveys published until January 2009. Surveys conducted in Australia, Canada, Europe, New Zealand, and the United States with at least 100 adult cancer patients were included. Detailed information on methods and results was independently extracted by 2 reviewers. Methodological quality was assessed using a criteria list developed according to the STROBE guideline. Exploratory random effects metaanalysis and metaregression were applied.

RESULTS

Studies from 18 countries (152; >65 000 cancer patients) were included. Heterogeneity of CAM use was high and to some extent explained by differences in survey methods. The combined prevalence for "current use" of CAM across all studies was 40%. The highest was in the United States and the lowest in Italy and the Netherlands. Metaanalysis suggested an increase in CAM use from an estimated 25% in the 1970s and 1980s to more than 32% in the 1990s and to 49% after 2000.

CONCLUSIONS

The overall prevalence of CAM use found was lower than often claimed. However, there was some evidence that the use has increased considerably over the past years. Therefore, the health care systems ought to implement clear strategies of how to deal with this. To improve the validity and reporting of future surveys, the authors suggest criteria for methodological quality that should be fulfilled and reporting standards that should be required.

Racial/ethnic differences in initiation of adjuvant hormonal therapy among women with hormone receptor-positive breast cancer

Mortality after breast cancer diagnosis is known to vary by race/ethnicity even after adjustment for differences in tumor characteristics. As adjuvant hormonal therapy decreases risk of recurrence and increases overall survival among women with hormone receptor-positive tumors, treatment disparities may play a role. We explored racial/ethnic differences in initiation of adjuvant hormonal therapy, defined as two or more prescriptions for tamoxifen or aromatase inhibitor filled within the first year after diagnosis of hormone receptor-positive localized or regional-stage breast cancer. The sample included women diagnosed with breast cancer enrolled in Kaiser Permanente Northern California (KPNC). Odds ratios [OR] and 95% confidence intervals [CI] compared initiation by race/ethnicity (Hispanic, African American, Chinese, Japanese, Filipino, and South Asian vs. non-Hispanic White [NHW]) using logistic regression. Covariates included age and year of diagnosis, area-level socioeconomic status, co-morbidities, tumor stage, histology, grade, breast cancer surgery, radiation and chemotherapy use. Our sample included 13,753 women aged 20-79 years, diagnosed between 1996 and 2007, and 70% initiated adjuvant hormonal therapy. In multivariable analysis, Hispanic and Chinese women were less likely than NHW women to initiate adjuvant hormonal therapy ([OR] = 0.82; [CI] 0.71-0.96 and [OR] = 0.78; [CI] 0.63-0.98, respectively). Within an equal access, insured population, lower levels of initiation of adjuvant hormonal therapy were found for Hispanic and Chinese women. Findings need to be confirmed in other insured populations and the reasons for under-initiation among these groups need to be explored.

Coping resources and self-rated health among Latina breast cancer survivors

PURPOSE/OBJECTIVES

To examine relationships between coping resources and self-rated health among Latina breast cancer survivors.

DESIGN

Cross-sectional telephone survey.

SETTING

Four northern California counties.

SAMPLE

330 Latina breast cancer survivors within one to five years of diagnosis.

METHODS

Telephone survey conducted by bilingual and bicultural interviewers.

MAIN RESEARCH VARIABLES

Predictors were sociodemographic and clinical factors, cancer self-efficacy, spirituality, and social support from family, friends, and oncologists. Outcomes were functional limitations and self-rated health.

FINDINGS

Twenty-two percent of women reported functional limitations (n = 73) and 27% reported poor or fair self-rated health (n = 89). Unemployment (adjusted odds ratio [AOR] = 7.06; 95% confidence interval [CI] [2.04, 24.46]), mastectomy (AOR = 2.67; 95% CI [1.06, 6.77]), and comorbidity (AOR = 4.09; 95% CI [1.69, 9.89]) were associated with higher risk of functional limitations; cancer self-efficacy had a protective effect (AOR = 0.4, 95% CI [0.18, 0.9]). Comorbidity was associated with higher risk of poor or fair self-rated health (AOR = 4.95; 95% CI [2.13, 11.47]); cancer self-efficacy had a protective effect (AOR = 0.3; 95% CI [0.13, 0.66]).

CONCLUSIONS

Comorbidities place Latina breast cancer survivors at increased risk for poor health. Cancer self-efficacy deserves more attention as a potentially modifiable protective factor.

IMPLICATIONS FOR NURSING

Nurses need to assess the impact of comorbidity on functioning and can reinforce patients' sense of control over cancer and clinician support.

Complementary and alternative medicine use among women receiving chemotherapy for ovarian cancer in 2 patient populations

OBJECTIVE

The authors evaluated attitudes toward complementary and alternative medicine (CAM) use in 2 populations of women receiving chemotherapy for epithelial ovarian cancer (EOC).

METHODS

Women with EOC currently being treated with chemotherapy at 2 tertiary cancer centers, in Canada and the United Kingdom, completed a self-administered questionnaire on attitudes and perceptions of CAM and types of CAM used within the previous month.

RESULTS

One hundred ninety-two patients (94 from Canada, 98 from United Kingdom) completed the questionnaire. Overall, 85 women (44%) were identified as CAM users. Complementary and alternative medicine use was more common among Canadian women (52%) compared with women from the United Kingdom (37%), P = 0.02. Participants used 71 different types of CAM, the majority (61%) taking multiple CAM. The frequency of CAM use was the same in primary compared with recurrent disease. Eighty-nine percent of CAM users considered it important for their oncologist to be aware of CAM use. Canadian women, however, were less likely to inform their physician (Canada: 50%; United Kingdom: 81%), P = 0.02. Motivations for CAM use were the same in both populations including assist healing (60%), boost the immune system (57%), improve quality of life (48%), and relieve symptoms (45%). Thirteen percent thought CAM could cure cancer, whereas 17% thought it would prevent recurrence.

CONCLUSIONS

Complementary and alternative medicine use is common in women receiving chemotherapy for EOC. Increasingly, interactions between CAM and prescribed medication are being identified. Oncologists should be aware and actively inquire about CAM use. Although patterns of CAM use differed, the motivation for starting CAM was similar, highlighting the need to address supportive care in all patients.

Use of Chinese medicine by women with breast cancer: a nationwide cross-sectional study in Taiwan

OBJECTIVES

The National Health Insurance (NHI) provided Western medicine (WM) and Chinese medicine (CM) in Taiwan. This study aims to explore CM use by women with breast cancer under NHI.

METHODS

Using NHI Research Database, a retrospective cross-sectional study was conducted. Women with breast cancer were identified by diagnosis codes. Their claims of CM and WM outpatient services of 2007 were analyzed.

RESULTS

Among 70,012 female breast cancer patients, the prevalence of insurance covered CM was 35.6%. Among all CM users, 4379 (17.5%) patients visited CM for breast cancer. More than half CM users (67.6%) had less than 6 visits and 16.3% users had more than 12 visits. The majority of CM users (87.6%) also used WM ambulatory services. Private clinics (76.7%) provided the most CM services, followed by private hospitals (16.9%). The most frequently used CM therapies were Chinese herbal medicine (80.5%), followed by acupuncture/traumatology manipulative therapies (22.3%). The average cost of CM was US$17.6 per visit and US$119.7 per user annually. CM users were more likely to be younger than 60 years old, employees, with higher income, and not living in Northern Taiwan.

CONCLUSIONS

A significant portion of breast cancer patients used insurance covered CM. Most CM users also used WM. The potential of drug-herb interactions should be concerned.

Use of multivitamins, folic acid and herbal supplements among breast cancer survivors: the black women's health study

BACKGROUND

Complementary and alternative medicine (CAM) use, including herbals and multivitamin supplements, is quite common in the U.S., and has been shown to be highest in breast cancer survivors. However, limited data are currently available for CAM usage among African Americans. Thus, we sought to determine the prevalence of multivitamins, folic acid and herbal supplement usage in African American breast cancer survivors, and to compare the characteristics of users and nonusers.

METHODS

A cohort study of breast cancer survivors, who completed the 1999 Black Women's Health Study questionnaire and self-reported having been diagnosed with breast cancer between 1995 and 1999, comprised the study population. In this study, the intake of natural herbs, multivitamins and folic acid at least three days per week within the past two years was used as a proxy for typical usage of this complimentary alternative medicine (CAM) modality.

RESULTS

A total of 998 breast cancer survivors were identified. Overall, 68.2% had used either herbals or multivitamin supplements or both. The three most frequently used herbals were garlic (21.2%), gingko (12.0%), and echinacea (9.4%). The multivariate analysis determined that single marital status (OR=1.58; 95%CI: 1.04-2.41), and alcohol consumption of 1-3 drinks per week (OR=1.86, 95%CI: 1.28-2.68) were significantly associated with increased herbal use. Multivitamin use was significantly lower among obese women (OR=0.66, 95%CI: 0.46-0.94) and current smokers (OR=0.53, 95%CI: 0.34-0.82).

CONCLUSIONS

A significant number of African American breast cancer survivors are using herbals and multivitamins as CAM modality. Additional research is needed to understand the impact of herbals and multivitamins in African American breast cancer survivors.

Predictors of yoga use among patients with breast cancer

OBJECTIVE

Emerging research suggests that yoga may be beneficial for reducing symptoms and improving quality of life among breast cancer patients. However, very little is known about the characteristics of breast cancer patients who use yoga; thus, this study seeks to identify the sociodemographic and clinical characteristics of yoga users among this population.

DESIGN

A cross-sectional survey study was conducted.

SETTING

The study was conducted at an outpatient breast oncology clinic at a large university hospital.

PARTICIPANTS

Three hundred postmenopausal breast cancer patients currently receiving aromatase inhibitors were included in this study.

MAIN OUTCOME MEASUREMENT

Self-reported use of yoga following the cancer diagnosis was collected along with sociodemographic and clinical data. Multivariate logistic regression was used to identify independent predictors of yoga use among breast cancer patients.

RESULTS

Of 300 participants, 53 (17.7%) reported having used yoga following cancer diagnosis. White patients were significantly more likely to use yoga than nonwhite patients (P = .02). Higher education level, lower BMI (body mass index), part-time employment status, previous chemotherapy, and radiation therapy were all associated with greater yoga use (all P < .05). Controlling for other factors, greater yoga use was independently associated with higher education level (adjusted odds ratio [AOR] 2.72, 95% confidence interval [CI], 1.15-6.46), and lower BMI (AOR 0.25, 95% CI, 0.09-0.66).

CONCLUSION

Yoga use following breast cancer diagnosis was substantially higher for white patients and those with lower BMI and higher education levels. Considering its potential benefits for symptom management in cancer, more research is needed to understand the attitudes and barriers to yoga use among individuals with nonwhite race, lower education, and higher BMI level. Such investigation will help design yoga programs that are aligned to the needs of these populations.

Methodological reflections on body-mind intervention studies with cancer patients

OBJECTIVE

Methodological reflection on the content, results and limitations of three body-mind intervention studies with cancer patients (CPs) in order to improve the quality of studies on body-mind interventions and to raise the potential value for CPs.

METHODS

A secondary analysis of a study on haptotherapy and two studies applying relaxing face massage, using a variety of well-being effect measures. Six methodological themes are discussed: (1) drop-out; (2) characteristics of participating patients, (3) participation of patients in other complementary interventions; (4) satisfaction of participants; (5) effects of the three interventions, and (6) role of response shift.

RESULTS

The three interventions showed limited effects after controlling for relevant confounding factors. They are mainly the small sample sizes, the low intensity of the intervention, the possible inadequate measure moments and the use of other CAM that may be responsible for the absence of effects.

CONCLUSIONS

Body-mind interventions require more methodological reflections to develop attractive and effective interventions for CPs. Attention needs to be paid to measuring short term effects, practically fitting research designs, and response shift.

PRACTICE IMPLICATIONS

Interventions should be intensive, repeated and not too short. The implementation of interventions requires attention to several organizational factors in the health care.

Antiproliferative effects of cucurbitacin B in breast cancer cells: down-regulation of the c-Myc/hTERT/telomerase pathway and obstruction of the cell cycle

Naturally occurring cucurbitacins have been shown to have anticancer, antimicrobial and anti-inflammatory activities. In this study, we determined the effects of cucurbitacin B extracted from the Thai herb Trichosanthes cucumerina L. on telomerase regulation in three human breast cancer cell lines (T47D, SKBR-3, and MCF-7) and a mammary epithelium cell line (HBL-100). Cell viability after treatment with cucurbitacin B, which is an active ingredient of this herb, was assessed. Telomeric Repeat Amplification Protocol (TRAP) assays and RT-PCR (qualitative and realtime) were performed to investigate activity of telomerase as well as expression of human telomerase reverse transcriptase (hTERT) and c-Myc. The c-Myc protein level was also determined in SKBR-3 and HBL-100 cells. Our results show that the cucurbitacin B inhibits growth and telomerase activity in the three breast cancer cell lines and exerts an obvious inhibitory effect in the estrogen receptor (ER)-negative breast cancer SKBR-3 cells. The expression of hTERT and c-Myc were also inhibited by cucurbitacin B, In addition, a clear reduction of c-Myc protein was observed after treatment in SKBR-3 cells even with a concentration of cucurbitacin B that was ten-times lower compared to the concentration used for HBL-100. Our findings imply that cucurbitacin B exerts an anticancer effect by inhibiting telomerase via down regulating both the hTERT and c-Myc expression in breast cancer cells.

Enhanced mammary progesterone receptor-A isoform activity in the promotion of mammary tumor progression by dietary soy in rats

Dietary contribution to breast cancer risk, recurrence, and progression remains incompletely understood. Increased consumption of soy and soy isoflavones is associated with reduced mammary cancer susceptibility in women and in rodent models of carcinogenesis. In rats treated with N-methyl-N-nitrosourea, dietary intake of soy protein isolate (SPI) reduced mammary tumor occurrence but increased incidence of more invasive tumors in tumored rats, relative to the control diet casein. Here we evaluated whether mammary tumor progression in tumor-bearing rats lifetime exposed to SPI is associated with deregulated progesterone receptor (PR) isoform expression. In histologically normal mammary glands of rats with invasive ductal carcinoma lesions, PR-A protein levels were higher for SPI- than casein-fed rats, whereas PR-B was undetectable for both groups. Increased mammary PR-A expression was associated with higher transforming growth factor-beta1, stanniocalcin-1, and CD44 transcript levels; lower E-cadherin and estrogen receptor-alpha expression; and reduced apoptotic status in ductal epithelium. Serum progesterone (ng/ml) (CAS: 25.94 +/- 3.81; SPI: 13.19 +/- 2.32) and estradiol (pg/ml) (CAS: 27.9 +/- 4.49; SPI: 68.48 +/- 23.87) levels differed with diet. However, sera from rats of both diet groups displayed comparable mammosphere-forming efficiency in human MCF-7 cells. Thus, soy-rich diets may influence the development of more aggressive tumors by enhancing PR-A-dependent signaling in premalignant breast tissues.

The ethyl acetate extract of PGP (Phellinus linteus grown on Panax ginseng) suppresses B16F10 melanoma cell proliferation through inducing cellular differentiation and apoptosis

ETHNOPHARMACOLOGICAL RELEVANCE

Phellinus linteus and Panax ginseng have been widely used as traditional herbal medicines to treat various diseases including cancer in East Asia.

AIM OF THE STUDY

The present study sought to investigate the possible mechanism in anti-proliferative effect of Phellinus linteus that was grown on Panax ginseng (PGP) on B16F10 melanoma cells.

MATERIALS AND METHODS

The anti-proliferative effect of PGP on B16F10 was evaluated by CCK-8 assays. Apoptotic cells were detected by flow cytometry analysis. The proteins involved in apoptosis and cellular differentiation were assessed by immunoblot analysis. Ginsenosides contents of PG or PGP were analyzed using HPLC.

RESULTS

The ethyl acetate fraction (EtOAc) of PGP exhibited the strongest anti-proliferative activity among PGP fractions (butanol or water) on B16F10 cells. PGP EtOAc extract showed stronger inhibitory effect than Panax ginseng (PG) or Phellinus linteus (PL) EtOAc extract on B16F10 melanoma cell proliferation. PGP EtOAc extract induced the dendrite-like structures and the melanin production in B16F10 cells. PGP EtOAc extract increased a sub-G1 cell population through inducing p53/p21 and activated caspase-8 protein expression in B16F10 cells. Notably, PGP EtOAc extract contained ginsenosides Rd, Rg3, Rb2, Rg1 and Rb1 more than PG EtOAc extract. Rd and Rg3 significantly inhibited B16F10 cell proliferation.

CONCLUSION

Our data suggest that PGP EtOAc extract inhibits B16F10 cell proliferation through inducing apoptosis and cellular differentiation.

A systematic literature review on response rates across racial and ethnic populations

OBJECTIVE

To conduct a systematic review examining whether minority ethnic populations participate in surveys as actively as the majority ethnic population.

METHODS

A literature and grey literature search was conducted using five online databases as well as government databases and reports, including the search terms: survey response rates or non-response rates and racial or ethnic populations (White, African American, Asian, and Hispanic); survey modes or methods (mail, telephone, face to face, e-mail); and response bias (non-response bias, response bias or social desirability). The search was limited to English language and articles published from January 1990 to June 2009. Article exclusions were based on further inclusion and exclusion criteria.

SYNTHESIS

Thirty-five articles were identified on ethnicities and response rates to survey modes. Six articles compared survey mode and response rate for multiple ethnic populations. Response rates ranged from 22.0% to 68.8% in Whites, and in other ethnic groups ranged from 15.4% in African Americans to 70.9% in Latino Americans. Among the 29 articles that presented survey mode and response rate for a specific ethnicity, the highest response rate reported was from African Americans (92.5%) and the lowest was from Cambodian Americans (30.3%).

CONCLUSION

Response rate varied across studies but was similar across ethnicities. Response rate may be related to many factors, including survey mode, length of questionnaire, survey language and cultural sensitivity to content. Our review indicates that ethnic populations who participate in surveys are as likely to participate in research as Whites. In literature, data validity across ethnicity is still unknown and should be studied in the future.

A qualitative investigation of cancer survivorship experiences among rural Hispanics

Cancer survivorship experiences were explored among Hispanic men and women with cancer and family members of cancer survivors, recruited from two rural Washington communities in the Lower Yakima Valley. Five focus groups were conducted from February 2006 to October 2007 with 31 women and 10 men. Disbelief, fear, sadness, strength, courage, faith, and hope were common reactions to diagnosis. Concerns about family/children, losing medical coupons, and feelings of depression/isolation were identified as challenges faced after diagnosis. Participants identified smoking and environmental exposures as causes of cancer, but many believed operating on tumors caused cancer to spread. Participants used conventional treatments but identified herbal/natural remedies as cures. Most participants reported negative experiences with physicians and believed their community would benefit from language-appropriate information regarding prevention and treatment. The importance of linking survivors through support groups was emphasized and information elicited from sessions has been used to organize survivor support groups in these two communities.

Use of complementary and alternative medicine for treatment among African-Americans: a multivariate analysis

BACKGROUND

The use of complementary and alternative medicine (CAM) is substantial among African-Americans; however, research on characteristics of African-Americans who use CAM to treat specific conditions is scarce.

OBJECTIVE

To determine what predisposing, enabling, need, and disease-state factors are related to CAM use for treatment among a nationally representative sample of African-Americans.

METHODS

A cross-sectional study design was employed using the 2002 National Health Interview Survey (NHIS). A nationwide representative sample of adult (> or =18 years) African-Americans who used CAM in the past 12 months (n=16,113,651 weighted; n=2,952 unweighted) was included. The Andersen Health Care Utilization Model served as the framework with CAM use for treatment as the main outcome measure. Independent variables included the following: predisposing (eg, age, gender, and education); enabling (eg, income, employment, and access to care); need (eg, health status, physician visits, and prescription medication use); and disease state (ie, most prevalent conditions among African-Americans) factors. Multivariate logistic regression was used to address the study objective.

RESULTS

Approximately 1 in 5 (20.2%) who used CAM in the past 12 months used CAM to treat a specific condition. Ten of the 15 CAM modalities were used primarily for treatment by African-Americans. CAM for treatment was significantly (P<.05) associated with the following factors: graduate education, smaller family size, higher income, region (northeast, midwest, west more likely than south), depression/anxiety, more physician visits, less likely to engage in preventive care, more frequent exercise behavior, more activities of daily living (ADL) limitations, and neck pain.

CONCLUSIONS

Twenty percent of African-Americans who used CAM in the past year were treating a specific condition. Alternative medical systems, manipulative and body-based therapies, and folk medicine, prayer, biofeedback, and energy/Reiki were used most often. Health care professionals should routinely ask patients about the use of CAM, but when encountering African-Americans, there may be a number of factors that may serve as cues for further inquiry.

Botanicals in dermatology: an evidence-based review

Botanical extracts and single compounds are increasingly used in cosmetics but also in over-the-counter drugs and food supplements. The focus of the present review is on controlled clinical trials with botanicals in the treatment of acne, inflammatory skin diseases, skin infections, UV-induced skin damage, skin cancer, alopecia, vitiligo, and wounds. Studies with botanical cosmetics and drugs are discussed, as well as studies with botanical food supplements. Experimental research on botanicals was considered to a limited extent when it seemed promising for clinical use in the near future. In acne therapy, Mahonia, tea tree oil, and Saccharomyces may have the potential to become standard treatments. Mahonia, Hypericum, Glycyrrhiza and some traditional Chinese medicines appear promising for atopic dermatitis. Some plant-derived substances like dithranol and methoxsalen (8-methoxypsoralen) [in combination with UVA] are already accepted as standard treatments in psoriasis; Mahonia and Capsicum (capsaicin) are the next candidates suggested by present evidence. Oral administration and topical application of antioxidant plant extracts (green and black tea, carotenoids, coffee, and many flavonoids from fruits and vegetables) can protect skin from UV-induced erythema, early aging, and irradiation-induced cancer. Hair loss and vitiligo are also traditional fields of application for botanicals. According to the number and quality of clinical trials with botanicals, the best evidence exists for the treatment of inflammatory skin diseases, i.e. atopic dermatitis and psoriasis. However, many more controlled clinical studies are needed to determine the efficacy and risks of plant-derived products in dermatology. Safety aspects, especially related to sensitization and photodermatitis, have to be taken into account. Therefore, clinicians should not only be informed of the beneficial effects but also the specific adverse effects of botanicals used for dermatologic disorders and cosmetic purposes.

A pilot trial of spirituality counseling for weight loss maintenance in African American breast cancer survivors

A continuing challenge in weight loss treatment is attaining maintenance of weight loss. The goal of this study was to develop a counseling method that would assist African American breast cancer survivors with weight loss maintenance. In this pilot study, 31 obese breast cancer survivors were recruited. Individualized, dietitian-led counseling by telephone and free Weight Watchers coupons were provided to all participants for 18 months. At the 6-month time point, women were randomized to receive spirituality counseling or not in addition to the standard program. The spirituality counseling was delivered via telephone using an 8-step framework. Subjects were asked to utilize daily meditation or prayer, daily readings, and the recording of thoughts in a journal. Mean weight loss from baseline to 6 months was a modest 2.0% of baseline weight. From 6 to 18 months, there was no further weight change in the spirituality arm and a gain of 0.7% in the dietitian-only arm. Despite little effect on weight loss, it did appear that spirituality counseling positively affected spiritual well-being (FACIT-Sp) scores and dietary quality. The spirituality counseling framework therefore may be further refined and useful for other health promotion studies with African American populations.

Patterns of the use of complementary and alternative medicine in women with metastatic cancer

BACKGROUND

Complementary and alternative medicine (CAM) has been widely used in the general population and in patients with cancer. Female sex and advanced cancer are 2 reported factors contributing to CAM use.

OBJECTIVE

The aim of this study was to examine the patterns of CAM use among women with metastatic cancer.

METHODS

A total of 68 women were enrolled into this cross-sectional study. All participants were receiving conventional treatment in a single inpatient oncology center. Data were collected from the women through a face-to-face interview guided by a questionnaire. On the basis of women's responses, all participants were divided into 2 groups: CAM users and nonusers.

RESULTS

The 2 cancers most frequently diagnosed in these women were gastrointestinal cancer (36.8%) and breast cancer (33.8%). Of 68 women, 40 (58.8%) reported the use of at least 1 type of CAM therapy after the diagnosis of cancer. There were no significant differences in the sociodemographic and clinical characteristics between CAM users and nonusers (P > .05). The most frequently used CAM method was herbal therapy (34.6%) and the second was nutritional supplements (17.9%). A considerable proportion (60.0%) of CAM users had not discussed their CAM use with their physicians or nurses. Four (10%) patients reported an adverse effect due to CAM use.

CONCLUSIONS

Our findings indicate that Turkish women with metastatic cancer seek to use CAM, with a small minority being at risk of potential adverse effects of certain CAM products.

IMPLICATIONS FOR PRACTICE

Because of the high prevalence of CAM therapies among women with metastatic cancer, oncology specialists and nurses should increase their knowledge about CAM therapies. Nurses are in a position to provide knowledge and education about CAM therapies and to develop protocols and guidelines about CAM use for patients with cancer.

Influence of ferutinin on bone metabolism in ovariectomized rats. II: role in recovering osteoporosis

The aim of the present investigation, which represents an extension of a previous study, was to investigate the effect of ferutinin in recovering severe osteoporosis due to estrogen deficiency after rat ovariectomy and to compare phytoestrogen effects with those of estrogens commonly used in hormone replacement therapy (HRT) by women with postmenopausal osteoporosis. The animal model used was the Sprague-Dawley ovariectomized rat. Ferutinin was orally administered (2 mg kg(-1) per day) for 30 or 60 days starting from 2 months after ovariectomy (i.e. when osteoporosis was clearly evident) and its effects were compared with those of estradiol benzoate (1.5 microg per rat twice a week, subcutaneously injected) vs. vehicle-treated ovariectomized (OVX) and sham-operated (SHAM) rats. Histomorphometric analyses were performed on trabecular bone of lumbar vertebrae (4th and 5th) and distal femoral epiphysis, as well as on cortical bone of femoral diaphysis. Bone histomorphometric analyses showed that ferutinin seems to display the same effects on bone mass recorded with estradiol benzoate, thus suggesting that it could enhance the recovery of bone loss due to severe estrogen deficiency in OVX rats. On this basis, the authors propose listing ferutinin among the substances representing a potential alternative for the treatment of postmenopausal osteoporosis, which occurs as a result of estrogen deficiency.

Polypharmacy in older adults with cancer

The definition of "polypharmacy" ranges from the use of a large number of medications; the use of potentially inappropriate medications, which can increase the risk for adverse drug events; medication underuse despite instructions to the contrary; and medication duplication. Older adults are particularly at risk because they often present with several medical conditions requiring pharmacotherapy. Cancer-related therapy adds to this risk in older adults, but few studies have been conducted in this patient population. In this review, we outline the adverse outcomes associated with polypharmacy and present polypharmacy definitions offered by the geriatrics literature. We also examine the strengths and weaknesses of these definitions and explore the relationships among these definitions and what is known about the prevalence and impact of polypharmacy.
