Zhang Y, Stopsack KH, Wu K, Song M, Mucci LA, Giovannucci E. Multivitamin use after diagnosis and prostate cancer survival among men with nonmetastatic prostate cancer. Br J Cancer 2024; 130:1709-1715. [PMID: 38491175 DOI: 10.1038/s41416-024-02651-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2023] [Revised: 02/29/2024] [Accepted: 03/04/2024] [Indexed: 03/18/2024] Open
Abstract
BACKGROUND Multivitamin use is common among cancer patients. Whether post-diagnostic multivitamin supplementation is beneficial for prostate cancer survival is largely unknown, and some evidence even suggests potential harm. METHODS We prospectively assessed post-diagnostic multivitamin use in relation to prostate cancer survival among 4756 men with nonmetastatic prostate cancer at diagnosis in the Health Professionals Follow-up Study (1986-2016). Cox regression models were used to evaluate the association between post-diagnostic multivitamin use and frequency and risk of lethal prostate cancer (distant metastases or prostate cancer-specific death) and all-cause mortality. RESULTS We observed 438 lethal prostate cancer and 2609 deaths during a median follow-up of 11 years. Compared to non-users, post-diagnostic multivitamin use was not associated with risk of lethal prostate cancer (HR [95% CI], 0.98 [0.74-1.30]) or all-cause mortality (1.00 [0.88-1.12]), after adjustment for potential confounders. Similarly, null associations were observed across various categories of use frequency. Compared to non-users, men who used multivitamins regularly (6-9 tablets/week) after cancer diagnosis had similar risk of lethal prostate cancer (0.96 [0.72-1.28]) and all-cause mortality (0.99 [0.88-1.12]). CONCLUSIONS We found no evidence that post-diagnostic multivitamin use among men with nonmetastatic prostate cancer was associated with better or worse survival in a well-nourished population.

Lilly MB, Wu C, Ke Y, Chen W, Soloff AC, Armeson K, Yokoyama NN, Li X, Song L, Yuan Y, McLaren CE, Zi X. A phase I study of docetaxel plus synthetic lycopene in metastatic prostate cancer patients. Clin Transl Med 2024; 14:e1627. [PMID: 38515274 PMCID: PMC10958125 DOI: 10.1002/ctm2.1627] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Revised: 02/20/2024] [Accepted: 02/25/2024] [Indexed: 03/23/2024] Open
Abstract
PURPOSE Our preclinical studies showed that lycopene enhanced the anti-prostate cancer efficacy of docetaxel in animal models. A phase I trial (NCT0149519) was conducted to identify an optimum dose of synthetic lycopene in combination with docetaxel (and androgen blockade [androgen deprivation therapy, ADT]), and to evaluate its effect on the safety and pharmacokinetics of docetaxel in men with metastatic prostate cancer. METHODS Subjects were treated with 21-day cycles of 75 mg/m2 docetaxel (and ADT), plus lycopene at 30, 90 or 150 mg/day. A Bayesian model averaging continual reassessment method was used to guide dose escalation. Pharmacokinetics of docetaxel and multiple correlative studies were carried out. RESULTS Twenty-four participants were enrolled, 18 in a dose escalation cohort to define the maximum tolerated dose (MTD), and six in a pharmacokinetic cohort. Docetaxel/ADT plus 150 mg/day synthetic lycopene resulted in dose-limiting toxicity (pulmonary embolus) in one out of 12 participants with an estimated probability of .106 and thus was chosen as the MTD. Lycopene increased the AUCinf and Cmax of plasma docetaxel by 9.5% and 15.1%, respectively. Correlative studies showed dose-related changes in circulating endothelial cells and vascular endothelial growth factor A, and reduction in insulin-like growth factor 1R phosphorylation, associated with lycopene therapy. CONCLUSIONS The combination of docetaxel/ADT and synthetic lycopene has low toxicity and favourable pharmacokinetics. The effects of lycopene on biomarkers provide additional support for the toxicity-dependent MTD definition. HIGHLIGHTS The maximum tolerated dose was identified as 150 mg/day of lycopene in combination with docetaxel/ADT for the treatment of metastatic prostate cancer patients. Small increases in plasma exposure to docetaxel were observed with lycopene co-administration. Mechanistically significant effects were seen on angiogenesis and insulin-like growth factor 1 signalling by lycopene co-administration with docetaxel/ADT.

Abstract
Prostate cancer (PCa) remains both a global health burden and a scientific challenge. We present a review of the molecular targets driving current drug discovery to fight this disease. Moreover, the preventable nature of most PCa cases represents an opportunity for phytochemicals as chemopreventive when adequately integrated into nutritional interventions. With a renovated interest in natural remedies as a commodity and their essential role in cancer drug discovery, Malaysia is looking towards capitalizing on its mega biodiversity, which includes the oldest rainforest in the world and an estimated 1200 medicinal plants. We here explore whether the list of top Malay plants prioritized by the Malaysian government may fulfill the potential of becoming newer, sustainable sources of prostate cancer chemotherapy. These include Andrographis paniculate, Centella asiatica, Clinacanthus nutans, Eurycoma longifolia, Ficus deltoidea, Hibiscus sabdariffa, Marantodes pumilum (syn. Labisia pumila), Morinda citrifolia, Orthosiphon aristatus, and Phyllanthus niruri. Our review highlights the importance of resistance factors such as Smac/DIABLO in cancer progression, the role of the CXCL12/CXCR4 axis in cancer metastasis, and the regulation of PCa cells by some promising terpenes (andrographolide, Asiatic acid, rosmarinic acid), flavonoids (isovitexin, gossypin, sinensetin), and alkylresorcinols (labisiaquinones) among others.

Prevalence of the Use of Herbal Medicines among Patients with Cancer: A Systematic Review and Meta-Analysis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:9963038. [PMID: 34055029 PMCID: PMC8149249 DOI: 10.1155/2021/9963038] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/10/2021] [Revised: 04/01/2021] [Accepted: 05/08/2021] [Indexed: 12/24/2022]
Abstract
Background Although herbal medicines are used by patients with cancer in multiple oncology care settings, the magnitude of herbal medicine use in this context remains unclear. The purpose of this review was to establish the prevalence of herbal medicine use among patients with cancer, across various geographical settings and patient characteristics (age and gender categories). Methods Electronic databases that were searched for data published, from January 2000 to January 2020, were Medline (PubMed), Google Scholar, Embase, and African Index Medicus. Eligible studies reporting prevalence estimates of herbal medicine use amongst cancer patients were pooled using random-effects meta-analyses. Studies were grouped by World Bank region and income groups. Subgroup and meta-regression analyses were performed to explore source of heterogeneity. Results In total, 155 studies with data for 809,065 participants (53.95% female) met the inclusion criteria. Overall, the pooled prevalence of the use of herbal medicine among patients with cancer was 22% (95% confidence interval (CI): 18%–25%), with the highest prevalence estimates for Africa (40%, 95% CI: 23%–58%) and Asia (28%, 95% CI: 21%–35%). The pooled prevalence estimate was higher across low- and middle-income countries (32%, 95% CI: 23%–42%) and lower across high-income countries (17%, 95% CI: 14%–21%). Higher pooled prevalence estimates were found for adult patients with cancer (22%, 95% CI: 19%–26%) compared with children with cancer (18%, 95% CI: 11%–27%) and for female patients (27%, 95% CI: 19%–35%) compared with males (17%, 95% CI: 1%–47%). Conclusion Herbal medicine is used by a large percentage of patients with cancer use. The findings of this review highlight the need for herbal medicine to be integrated in cancer care.

Abstract
The aim of this study was to assess the extent of Complementary and Alternative Medicine (CAM) usage, especially herbal preparations, in treating urinary tract illnesses, and their perceived efficacy. This was a cross-sectional survey that used a convenience sample of 278 adults who reported having any form of urinary tract illness. During the last 3 months, 105 (37.8%) of participants had used CAM for various urinary tract conditions, of which, 87 (82.9%) used herbal remedies. Urinary tract infections (UTIs) were the most reported urinary condition (n = 77, 73.3%) among CAM users. The most commonly used herbs were, parsley (n = 54, 19.2%), followed by chamomile (n = 29, 10.4%), barley (n = 20, 7.4%) and ginger (n = 18, 6.7%).The study provides an overview of various CAM remedies used to treat urinary tract illnesses in the Jordanian society, which would draw attention to the necessity of conducting interventional studies to evaluate the efficacy and safety of CAMs in treating urinary tract illnesses, either as stand-alone or adjuvant treatment.

Abstract
Several randomized controlled trials (RCTs) have investigated the effect of lycopene supplementation on serum levels of prostate-specific antigen (PSA) in patients with prostate cancer. However, results have been inconclusive. We systematically searched PubMed, Embase, and Scopus up to January 2020 to find RCTs investigating the effect of lycopene supplementation on serum levels of PSA in patients with non-metastatic prostate cancer. Using a random-effects model, the reported risk estimates were pooled. A total of six trials were included in the final analysis. we found no significant effect of lycopene on circulating PSA (WMD: -0.60, 95% CI: -2.01, 0.81 µg/L). However, we observed a significant reducing effect when the analysis was confined to studies that included patients with higher baseline levels of PSA (≥6.5 µg/L) (WMD: -3.74 µg/L, 95% CI: -5.15, -2.32, P < 0.001). Subgroup analysis based on the duration of intervention did not result in any significant effect. Non-linear dose-response analysis did not show any significant effects of lycopene dosage (Pnon-linearity = 0.50) and duration of the intervention (Pnon-linearity = 0.63) on serum levels of PSA. Although lycopene supplementation did not produce any reduction in PSA levels overall, a significant reducing effect was observed in patients with higher levels of baseline PSA. Due to the heterogeneity of our results, further high-quality clinical trials with long-term duration are required to determine the efficacy of lycopene in patients with non-metastatic prostate cancer.

BMJ Open 2020; 10:e033159.

Abstract
OBJECTIVE This study aimed to use the Korean Health Panel Survey (KHPS) data to identify the key factors that influence decisions regarding the use of traditional Korean medicine (TKM) by privately insured persons. DESIGN A retrospective study on episodic KHPS data from 2009 to 2013. SETTING Nationwide-based survey using the KHPS data. PARTICIPANTS The study included outpatients aged ≥20 years who had used private medical insurance at least once during the 5 years of the survey. After excluding cases where TKM was not used and those with missing values, this study ultimately included 1874 patients. PRIMARY AND SECONDARY OUTCOME MEASURES The main dependent variable was TKM utilisation (number of outpatient visits and outpatient costs of TKM). We used multiple linear regression analysis to identify determinants of TKM while controlling for clustered errors. RESULTS Approximately 6.1% (1874) of all doctor visits (30 982) were characterised as TKM services. For therapeutic purposes, TKM visits increased despite not being guaranteed in private health insurance (coefficient=3.0, p=0.045) and TKM outpatient costs decreased (coefficient=-0.3, p=0.001). Women used more therapeutic TKM services than men (coefficient=2.8, p<0.001). Older patient groups used more therapeutic TKM services than younger patient groups (coefficient=11.5, p=0.012), but paid less on outpatient costs than younger groups (coefficient=-1.0, p=0.001). For preventive services, sex and age were not statistically significant factors. Regardless of the purpose of the visit, the more chronic diseases, the more people who have previously experienced TKM service use more TKM services (p<0.001). CONCLUSIONS Despite a policy to reduce services that are not guaranteed by private health insurance, the increase in the number of outpatient visits for uncovered therapeutic TKM services implies a high public need for TKM in Korea.

Abstract
In Australia, it is estimated that around 17% to 87% of cancer patients have used
one form of complementary therapy during their cancer treatment. There are
numerous reasons and contributing factors for cancer patients to consider using
complementary and alternative medicine (CAM). CAM information and products are
readily available. However, the level of evidence to support the benefits of use
in the cancer setting is limited, and the associated adverse effects and
interactions with conventional medicine may not be fully studied. Besides, not
all health professionals favor the concept of integrative health approaches, or
have the confidence in dealing with CAM due to a lack of knowledge and
standardization of practices. A thematic review of the literature was performed
on the main contributing factors to cancer patients’ use of CAM, as well as the
current issues that may be encountered by the patients and health
professionals.

J Cancer Surviv 2017; 11:421-430. [PMID: 28150122 DOI: 10.1007/s11764-017-0599-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2016] [Accepted: 01/16/2017] [Indexed: 10/20/2022]
Abstract
PURPOSE The purpose of this study was to assess the use of non-conventional medicine (NCM) in a representative sample of French patients 2 years after cancer diagnosis. METHODS The study was based on data obtained in the VICAN survey (2012) on a representative sample of 4349 patients 2 years after cancer diagnosis. Self-reported data were collected at telephone interviews with patients. The questionnaire addressed the various types of non-conventional treatments used at the time of the survey. RESULTS Among the participants, 16.4% reported that they used NCM, and 45.3% of this group had not used NCM before cancer diagnosis (new NCM users). Commonly, NCMs used were homeopathy (64.0%), acupuncture (22.1%), osteopathy (15.1%), herbal medicine (8.1%), diets (7.3%) and energy therapies (5.8%). NCM use was found to be significantly associated with younger age, female gender and a higher education level. Previous NCM use was significantly associated with having a managerial occupation and an expected 5-year survival rate ≥80% at diagnosis; recent NCM use was associated with cancer progression since diagnosis, impaired quality of life and higher pain reports. CONCLUSION This is the first study on NCM use 2 years after cancer diagnosis in France. In nearly half of the NCM users, cancer diagnosis was one of the main factors which incited patients to use NCM. Apart from the NCM users' socioeconomic profile, the present results show that impaired health was a decisive factor: opting for unconventional approaches was therefore a pragmatic response to needs which conventional medicine fails to meet during the course of the disease. IMPLICATIONS FOR CANCER SURVIVORS Better information of patients and caregivers is needed to allow access to these therapies to a larger population of survivors.

Lesson From Comparison of CAM Use by Women With Female-Specific Cancers to Others: It's Time to Focus on Interaction Risks With CAM Therapies. Integr Cancer Ther 2016; 6:313-44.

Abstract
There has been no examination as to whether the prevalence of complementary and alternative medicine (CAM) use, as well as personal factors associated with CAM use and predictive of CAM use for women with female-specific cancers, is similar to those in other diagnostic groups. The purpose of this review is to compare CAM use and personal factors associated with and predictive of CAM use by women with female-specific cancers to samples of other diagnostic groups. If it is the case that CAM use is similar across various types of samples, then it may be unnecessary to continue to study detailed CAM use by those in separate diagnostic groups and instead focus energies on the examination of CAM therapies that may have risks for interaction with conventional therapies, such as biologically based therapies. The researcher concludes that we are now in an era in which we need to use our restricted time, human resources, and finances to examine biologically based CAM use that may carry high risks for interactions or toxicities for specific groups under examination, rather than examine global CAM use, unless the situation warrants such all-inclusive study.

Low-lycopene containing tomato powder diet does not protect against prostate cancer in TRAMP mice. Nutr Res 2015; 35:882-890.

Abstract
Previously, tomato powder (TP) diets initiated postweaning have been shown to be effective in reducing prostate cancer in the transgenic adenocarcinoma of the mouse prostate (TRAMP) model. The TRAMP model develops and progresses through all stages of carcinogenesis similarly to humans. We hypothesized that a 10% TP diet intervention after puberty would reduce carcinogenesis at 12, 16, and 20 weeks of age in TRAMP mice. Eight-week-old male C57BL/6 X FVB F1 TRAMP mice were randomized to consume either an AIN-93G + 10% TP diet (n = 90) or the AIN-93G control diet (n = 88) and randomized to 1 of 3 end point ages: 12 (n = 59), 16 (n = 60), or 20 (n = 59) weeks of age. There was no difference between diets in overall cancer incidence at any time point. However, at 16 weeks of age, TP significantly increased high-grade PIN (P = .014) and significantly decreased poorly differentiated (P = .024) lesions compared with the control diet suggesting a delay in the progression of prostate cancer. Two variables that may explain the modest effect of TP in this study are as follows: the low amount of lycopene in the TP diet (12.3 ppm) and the timing of the intervention (8 weeks of age). The TP diet contained 30-fold less lycopene than previous studies in our laboratory. In addition, the initiation of the diet intervention time of 8 weeks of age instead of 4 weeks of age may have been too late in cancer progression to substantially impact carcinogenesis. In conclusion, a low-lycopene TP intervention failed to reduce carcinogenesis in TRAMP mice.

Abstract
OBJECTIVE Many patients use complementary and alternative medicine (CAM) as primary treatment or symptom relief for a variety of illnesses. This study was designed to investigate the influence of surgical removal of a tumor-bearing urogenital organ on CAM use. METHODS From 2007 to 2011, 350 patients underwent major urological surgery for kidney, prostate, or bladder cancer at the Goethe-University Hospital, Frankfurt, Germany. Data from 172 patients (49%), who returned a questionnaire, were retrospectively evaluated using the hospital information system along with the questionnaire to objectify CAM use 2 years before and after surgery. RESULTS From the 172 patients returning questionnaires, 56 (33%) used CAM before and/or after surgery and 116 (67%) never used CAM. Of the 56 CAM users, 30 (54%) used CAM presurgery and 53 (95%) used CAM postsurgery, indicating a significant change of mind about CAM use. Patients of German nationality used CAM significantly more than patients of other nationalities. Higher educational status (high-school diploma or higher) was a significant factor in favor of CAM use. The most common type of CAM used before/after surgery was an alternative medical system (63/49%), a manipulative and body-based method (50/19%), and a biological-based therapy (37/32%). Information about CAM, either provided by medical professionals or by other sources, was the main reason determining whether patients used CAM or not. CONCLUSION The number of patients using CAM almost doubled after surgical removal of a cancer-bearing organ. Better awareness and understanding of CAM use by medical professionals could improve patient counseling.

Abstract
BACKGROUND In Germany, many prostate cancer patients use complementary medicine (CM) or have an interest in these treatment approaches; however, the information and consultation situation of cancer patients is insufficient and therefore the Competence Network Complementary Medicine in Oncology (COCON) was launched by the German Cancer Aid Society. One of the projects of the COCON examines the use of CM and the information and counseling needs regarding these topics in various groups of cancer patients. The focus of this article is on the qualitative study reporting selected results for the subgroup of prostate cancer patients. STUDY DESIGN AND STUDY METHODS A total of 19 semi-structured qualitative interviews with prostate cancer patients were conducted regarding the use of CM as well as their information and consultation needs. RESULTS It was found that the patients interviewed discussed various issues surrounding nutrition, particularly a healthy diet, the selective use of certain foods and the use of dietary supplements. Additional themes mentioned by interviewees were physical exercise, psychological well-being, mistletoe therapy, homeopathy and traditional Chinese medicine. Patients indicated that they wanted more information and counseling opportunities with regards to CM. They also expressed a desire for more holistic care. CONCLUSION The results show that prostate cancer patients use a range of CM and have a need for information about CM. Prostate cancer patients are in a special situation because of a regular feedback on the prostate-specific antigen (PSA) value. This should be taken into consideration in consultation with prostate cancer patients regarding CM.

Abstract
Lycopene/tomato has been discussed as a potential effecter in the prevention and therapy of prostate cancer; however, no systematic review has been reported to illustrate its effect recently. In the present study, a meta-analysis was carried out to determine whether intake of lycopene and tomato/tomato products could reduce the risk of prostate cancer. Eleven cohort studies and six nested case-control studies were identified through searching of international journal databases and reference lists of relevant publications. Two reviewers independently assessed the study quality and extracted data from each identified study; only studies with sufficient quality were included in the review. The main outcome of interest was incidence of prostate cancer. Compared with consumers of lower raw tomato intake, the odds ratio (OR) of incidence of prostate cancer among consumers of higher raw tomato intake was 0.81 [95% confidential interval (CI) 0.59-1.10]; for consumers of higher level of cooked tomato intake versus lower cooked tomato intake, this OR was 0.85 (95% CI 0.69-1.06); the OR of higher lycopene intake versus lower lycopene intake for prostate cancer was 0.93 (95% CI 0.86-1.01) and the OR for higher level of serum lycopene versus lower serum lycopene level was 0.97 (95% CI 0.88-1.08). It's suggested that tomato may play a modest role in the prevention of prostate cancer. Further research would be needed to determine the type and quantity of tomato products regarding their potential in preventing prostate cancer.

Abstract
Lycopene is a phytochemical that belongs to a group of pigments known as carotenoids. It is red, lipophilic and naturally occurring in many fruits and vegetables, with tomatoes and tomato-based products containing the highest concentrations of bioavailable lycopene. Several epidemiological studies have linked increased lycopene consumption with decreased prostate cancer risk. These findings are supported by in vitro and in vivo experiments showing that lycopene not only enhances the antioxidant response of prostate cells, but that it is even able to inhibit proliferation, induce apoptosis and decrease the metastatic capacity of prostate cancer cells. However, there is still no clearly proven clinical evidence supporting the use of lycopene in the prevention or treatment of prostate cancer, due to the only limited number of published randomized clinical trials and the varying quality of existing studies. The scope of this article is to discuss the potential impact of lycopene on prostate cancer by giving an overview about its molecular mechanisms and clinical effects.

Abstract
Men receiving radiation for prostate cancer frequently want to know what steps they can take to optimize their chance of cure and reduce their risk of side effects. A variety of modifiable behaviors, medications, and complementary alternative medicine interventions have been investigated in this regard. In this review, we summarize data on tobacco use, exercise, statins and aspirin, and vitamins. There is limited randomized data supporting any of the interventions and additional studies are needed before clinicians can confidently inform their patients regarding what steps to take to improve their outcomes.

Abstract
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.

Abstract
The experience of men who have completed cancer treatment and transitioned into survivorship is not well understood; therefore, a qualitative, descriptive, narrative analysis was conducted with open-ended questions that participants responded to annually during the course of a 10-year period. The participants expressed that the experience was complex and three themes were identified: "symptoms," "can't go back," and "needs." Time also emerged as an important concern. Participants indicated that sexual and physical symptoms impacted their entire life and that acknowledgment, information, and help from others were important to their recovery. Returning to baseline functioning was no longer possible; rather, a new normal now existed. The findings will help oncology nurses better understand the experience of being a prostate cancer survivor. The need for long-term interventions with information delivered prior to, during, and beyond the treatment process was identified. Clinical interventions should move toward a more integrated approach that helps men develop their new normal.

Abstract
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.

Abstract
UNLABELLED The purpose of this study was to examine the prevalence and predictors of complementary and alternative medicine (CAM) use among rural patients with localized prostate cancer. The study also examined the participants' disclosure of CAM use to their physicians. Baseline and 6-month follow-up data were taken from a study examining the factors that influence treatment choice and quality of life among men diagnosed with and being treated for localized prostate cancer residing in rural southwest Georgia (N = 321). A total of 291 participants were interviewed at baseline and 6-month follow-up. FINDINGS At baseline, 26.4% reported ever using CAM. Among them, dietary supplements were the most commonly used (75%), and 56% of patients did not disclose their CAM use to their physicians. At 6-month follow-up, 11% of the study sample reported using CAM since starting treatment (half of these were new users). The proportions of CAM users who reported taking dietary supplements after treatment were significantly lower than the corresponding proportions before treatment. CAM use after treatment was more common among those who selected surgery and watchful waiting. While 44% of the sample disclosed using CAM to their doctors before treatment, 61% after treatment began (P = 0.05). We found that CAM use after cancer treatment in this population was markedly less common than in nationally reported data for cancer patients. In line with national patterns, younger and more educated rural patients were significantly more likely to have ever used CAM and to use it after treatment.

Abstract
BACKGROUND Selenium supplementation is a popular and broadly adopted complementary oncological treatment option. The aim of the study was the evaluation of the necessity and the indication for selenium therapy in prostate cancer patients. METHODS 295 consecutive patients after radical prostatectomy were evaluated for oncological, basic laboratory and lifestyle characteristics. The selenium level was measured using graphite furnace atom absorption spectroscopy. RESULTS The median selenium level was 103.4 (72.9–142.1) μg/l. Correlations were found between a low selenium level and progressed cancer disease, positive lymph node status, chronic nicotine and alcohol abuse, and chronic multiple medications. CONCLUSION Based on a documented low selenium level in 96.3% of investigated prostate cancer patients and the known consequences of an insufficient selenium supply, a targeted selenium supplementation is recommended. Selenium therapy should be part of an individual medical nutritional and lifestyle intervention.

Abstract
BACKGROUND Prostate cancer is a common cause of death in developed countries, yet the benefits of screening for prostate cancer still remain controversial. A prostate-specific antigen (PSA) test result greater than 4 ng/mL (nanograms/millilitre) has commonly been used as the cut-off level for seeking further tests to diagnose the presence (or absence) of prostate cancer. An increase in PSA levels may not necessarily be associated with an increased risk of prostate cancer, as PSA levels may also be increased in men with benign prostatic hyperplasia and prostatitis. Despite the uncertainty of the net benefit of early detection and treatment, safe and effective methods to prevent prostate cancer are of value. Consumers, seeking greater involvement in their healthcare, are increasingly turning to lifestyle modification and complementary and alternative medicines (CAMs) to maintain their health and prevent disease. Lycopene is a member of the carotenoid family, which is found abundantly in tomatoes, tomato-based products, strawberries, and watermelon. It has been hypothesised that lycopene is a strong antioxidant, which may lower the risk of cancer (including prostate cancer) in people who have diets rich in lycopene. OBJECTIVES To determine whether lycopene reduces the incidence of prostate cancer and prostate cancer-specific mortality. Secondary objectives include changes in PSA levels, prostate symptoms and the nature of adverse events associated with lycopene use. SEARCH METHODS Electronic searches were conducted across MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials (CENTRAL) databases. No language or other limitations were imposed. SELECTION CRITERIA Randomised controlled trials (RCTs) that investigated the use of lycopene for the prevention of prostate cancer were eligible for inclusion in this review. DATA COLLECTION AND ANALYSIS A search of electronic databases, performed in August 2011, identified 64 citations. All articles were selected for full-text review. From these citations, three studies were identified as meeting the inclusion criteria. Handsearching did not provide any additional studies. MAIN RESULTS Three RCTs, with a total of 154 participants were included in this review. None of the studies reported data on prostate cancer mortality. All of the included studies differed with respect to design, participants included and allocation of lycopene. This clinical heterogeneity limits the value on the pooled estimated of the meta-analyses. The methodological quality of two of the three included studies was assessed as posing a 'high' risk of bias. Meta-analysis indicated no statistical difference in PSA levels between men randomised to receive lycopene and the comparison group (MD (mean difference) -0.34, 95% CI (confidence interval) -2.01, 1.32). Only one study reported incidence of prostate cancer (10% in the lycopene group versus 30% in control group). The level of lycopene was also not statistically different in men randomised to receive lycopene and the comparison group (MD 0.39 µg/mL (micrograms/millilitre), 95% CI -0.19, 0.98). No other meta-analyses were possible since other outcomes assessed only had one study contributing data. AUTHORS' CONCLUSIONS Given that only three RCTs were included in this systematic review, and the high risk of bias in two of the three studies, there is insufficient evidence to either support, or refute, the use of lycopene for the prevention of prostate cancer. Similarly, there is no robust evidence from RCTs to identify the impact of lycopene consumption upon the incidence of prostate cancer, prostate symptoms, PSA levels or adverse events.

Abstract
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.

Abstract
Use of herbal medicine is popular among cancer patients. This study aimed to explore the coprescription of CHM and WM among prostate cancer patients in Taiwan. This cross-sectional retrospective study used a population-based database containing one million beneficiaries of National Health Insurance. Claims and prescriptions were analyzed. In 2007, 218 (22.4%) prostate cancer patients were CHM users. Among CHM users, 200 (91.7%) patients with 5618 (79.5%) CHM prescriptions were on coprescription of CHM and WM. A total of 484 types of CHM and 930 types of WM were used. The most commonly used CHMs on coprescription were Shu Jing Huo Xue Tang, Ma Zi Ren Wan, and Xue Fu Zhu Yu Tang. The most commonly used WMs on coprescription were magnesium oxide, amlodipine, and aspirin. The average number of prescriptions per user per year was 261.2 versus 151.7 in all (P < 0.001), 123.6 versus 76.9 in WM (P = 0.033), and 34.8 versus 5.1 in CHM (P < 0.001) for patients with and without coprescription, respectively. In conclusion, use of CHM among prostate cancer patients was popular in Taiwan. Most CHMs were used with WM concurrently. The potential drug-herb interactions should be investigated, especially for patients with more prescriptions.

Abstract
The National Health Insurance (NHI) covers Western medicine and Chinese medicine (CM) in Taiwan. The present study aimed to investigate the trends and characteristics of CM use among prostate cancer patients before and after diagnosis. A retrospective longitudinal cohort study was carried out using the NHI research database. The present study cohort consisted of 4720 prostate cancer patients diagnosed in 2004. Claims of CM services of these patients between 2003 and 2008 were analyzed. The prevalence of CM use of this cohort was 25.8%, 26.8%, 23.6%, 22.4%, 22.0% and 21.1% in 2003-2008, respectively. Overall, 52.6% of this cohort had ever used CM. In the first year of diagnosis, there was the greatest increase of new CM users (12.1%). The total number of CM users and visits reached the peak in 2004 and decreased in the subsequent years (2005-2008). The average number of CM visits per user was 6.7, 6.7, 7.0, 7.1, 7.3 and 7.2 in 2003-2008, respectively. The most frequently recorded principal diagnosis of CM visits was musculoskeletal diseases (21.4%), symptoms/signs (17.6%) and neoplasms (11.7%). Chinese herbal medicine (75.1%) was the most commonly used, followed by acupuncture/traumatological manipulative therapies (29.7%). Patients using CM before diagnosis tended to be CM users after diagnosis. The increase of CM use over the first year of prostate cancer diagnosis can be primarily attributed to an increase of new CM users, rather than of CM visits per users.

Abstract
BACKGROUND Taiwan National Health Insurance (NHI) provides Western medicine and Chinese medicine (CM). This study aims to explore the trends of CM use among prostate cancer patients under NHI. METHODS Claims of CM outpatient services from 1996 to 2008 were obtained from NHI Research Database. CM visits of prostate cancer patients were identified. Claims with diagnosis code of prostate cancer were defined as cancer-specific visits. RESULTS Among 78 323 prostate cancer patients identified during 1996-2008, there were 30 383 (38.8%) CM users and 327 063 CM outpatient visits. The prevalence of CM use in each cross-sectional year increased slightly from 24.9% to 25.6%. Most CM visits (92.7%) were non-cancer-specific. There were greater increases in the proportion of cancer-specific CM visits (from 2.3% to 10.6%) and high-utility CM users (from 3.1% to 19.7%). Most CM services were provided by private clinics (68.1% to 79.2%). The most frequently used CM therapies were Chinese herbal medicine (72.8% to 78.8%), followed by acupuncture/traumatology manipulative therapies (28.1% to 36.8%). Total CM cost increased from $122 247 to $825 454. The average cost per CM visit increased from $14.0 to $19.6. The annual cost per CM user increased from $88.0 to $134.4. Copayment accounted for 6.6% to 11.7%. CONCLUSIONS There was a trend of increased CM use among prostate cancer patients under NHI. Although prostate cancer patients used CM mostly for noncancer diseases, CM visits for prostate cancer increased remarkably. The utilization patterns of CM visits for cancer and for noncancer diseases were distinctly different.

Long-term prostate cancer survivors with low socioeconomic status reported worse mental health-related quality of life in a population-based study. Urology 2010; 76:1224-30.

Abstract
OBJECTIVE To explore whether socioeconomic status (SES) was associated with health-related quality of life (HRQL) and health care use among long-term prostate cancer survivors. PATIENTS AND METHODS Through urologists in the Comprehensive Cancer Center South, all 5- to 10-year prostate cancer survivors known in the Eindhoven Cancer Registry without disease progression were invited to complete the 36-item Short Form Health Survey (SF-36), the Expanded Prostate Cancer Index, and the Dutch sexual activities module. Multivariate linear regression assessed the effect of SES (based on home value and household income) on HRQL and health care use. RESULTS Five-hundred eighty-four patients (response rate 81%) were included. Survivors with a low SES exhibited lower mental SF-36 scores (6-16 points on a 0-100 scale), independent of sociodemographic and clinical characteristics (P < .05), and hardly any differences in physical SF-36 subscales, sexual function, and urinary and bowel function and bother. Presence of serious comorbidity had a stronger predictive value for HRQL than SES. Health care use did not seem to be associated with SES. CONCLUSIONS Prostate cancer survivors with a low SES exhibited a worse mental but not physical HRQL than those with a higher SES. Long-term health outcomes of patients with low SES may be maximized by paying extra attention to comorbid conditions.

Abstract
BACKGROUND This pilot randomized controlled trial (RCT) examined the clinical effects of 2 complementary (CAM) therapies, relaxation response therapy (RRT) and Reiki therapy, in men being treated with external beam radiotherapy (EBRx) for prostate cancer. METHODS Study participants were randomly assigned to weekly RRT, Reiki therapy twice weekly, or wait-list control. Well-validated instruments measured anxiety (STAI), depression (CES-D), and quality of life in cancer patients (FACT-G) at randomization and 3 subsequent time points. RESULTS Fifty-four men were randomized, and 16 of 18 (89%) of RRT and 15 of 18 (83%) of Reiki patients completed the intervention protocol. No statistically significant difference was found between the RRT, Reiki, and control groups on total scores for the STAI, CES-D, or FACT-G instruments at any time point. However, at the end of the intervention, significant improvement was found on the emotional well-being subscale of the FACT-G quality of life scale in the RRT group compared with the Reiki and control groups (P = .01). In participants who were classified as "anxious" at baseline, statistically significant improvement occurred in the RRT group (P = .02), and a positive trend was found in the Reiki group (P = .10). CONCLUSIONS This pilot study documented the feasibility of conducting a RCT of CAM therapies in men undergoing EBRx for prostate cancer. Relaxation response therapy improved emotional well being and eased anxiety in participants. Reiki therapy also had a positive effect in anxious patients. A larger study to verify and better define the benefits of these therapies in men with prostate cancer is warranted.

Abstract
The aim of this paper is to evaluate the reliability of websites providing health food information for cancer patients and, to assess the status to get this information online. We used four common Japanese search engines (Yahoo!, Google, goo, and MSN) to look up websites on Dec. 2, 2008. The search keywords were "health food" and "cancer". The websites for the first 100 hits generated by each search engine were screened and extracted by three conditions. We extracted 64 unique websites by the result of retrieval, of which 54 websites had information about health food factors. The two scales were used to evaluate the quality of the content on 54 websites. On the scale of reliability of information on the Web, the average score was 2.69+/-1.70 (maximum 6) and the median was 2.5. The other scale was matter need to check whether listed to use safely this information. On this scale, the average score was 0.72+/-1.22 (maximum 5) and the median was 0. Three engines showed poor correlation between the ranking and the latter score. But several websites on the top indicated 0 score. Fifty-four websites were extracted with one to four engines and the average number of search engines was 1.9. The two scales were positively correlated with the number of search engines, but these correlations were very poor. Ranking high and extraction by multiple search engines were of minor benefit to pick out more reliable information.

Abstract
BACKGROUND Taiwan's National Health Insurance (NHI) is a comprehensive and universal program, providing Western medicine (WM) and Chinese medicine (CM). This study aims to explore CM use among prostate cancer patients in NHI. METHODS A cross-section retrospective analysis was conducted using registration and claim data sets from the NHI Research Database. In 2007, 22,352 prostate cancer patients with 265,497 visits of CM and WM ambulatory services were identified. Patient demographics, patterns of therapies, and costs were analyzed. RESULTS In 2007, 592 prostate cancer patients (2.6%) had 4141 CM outpatient visits (7.0 on average). The median age was 73.9. The majority (90.5%) of CM users also used WM ambulatory services. About one third of CM outpatient services were provided by private clinics. The most frequently used CM therapies were Chinese herbal medication (93.6%), followed by acupuncture/traumatology manipulative therapies (7.0%). CM accounted for 0.2% expenditure ($87,500) and 1.6% visits of ambulatory services. The average cost per visit for WM was 6.3 times higher than that for CM ($133.6 vs $21). CONCLUSIONS The prevalence and costs of insurance-covered CM among prostate cancer patients were low. Most prostate cancer patients did not use insurance-covered CM. The majority of CM users also used WM. CM appeared to play a complementary rather than an alternative role.

Abstract
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.

Abstract
BACKGROUND AND AIM Little is known about the use of herbal medicines by people living with cancer in the UK. This systematic review aimed to estimate the prevalence of herbal medicine use by this group, the characteristics of users, factors motivating use, and attitudes towards herbal remedies. DESIGN AND METHODS Fifteen electronic databases were searched. People who were research-active in the field were contacted and asked about further published or unpublished work. All studies identified as relevant to the purpose of the review were assessed. Searches were not restricted by publication type or date. RESULTS Of 1288 unique references identified, 11 met the eligibility criteria. Studies were excluded where research had been conducted outside the UK; where information on herbal medicine use was not differentiated from that relating to complementary and alternative therapies more broadly, and where neither prevalence of use nor information on user characteristics was included. Prevalence estimates ranged from 3.1 to 24.9%. Most studies did not obtain information specifically on herbal medicines and only one examined the characteristics and motivations of users of herbal medicines as distinct from complementary and alternative therapies in general. CONCLUSION The high degree of heterogeneity of methodology, sample selection and characteristics, and research design resulted in a wide range of estimates of prevalence. Well-designed research is needed to define the evidence base about the herbal medicines taken by people with cancer in the UK, the reasons for use, knowledge about possible effects and potential risks, and where people seek information.

Abstract
Lycopene has a chemopreventive effect against prostate cancer but its role in prostate cancer progression is unknown; many patients increase their intake of lycopene, although there are no evidence-based guidelines to suggest an effect. Our objective was to conduct a systematic review of literature to evaluate the association between lycopene intake and prostate cancer progression. MEDLINE, EMBASE CINAHL Plus, Web of Science, AMED and CENTRAL databases were systematically searched using terms for lycopene and prostate cancer progression to identify studies published before January 2009. Eight intervention studies were identified (five with no control group; one with an unmatched control group; and two randomized controlled trials (RCTs)). An inverse association was observed between lycopene intake and PSA levels in six studies. The rates of progression measured by bone scan in one RCT were lower in the intervention group. Lycopene resulted in lowering cancer-related symptoms (pain, urinary tract symptoms), and severe toxicity or intolerance was not evident. However, the evidence available to date is insufficient to draw a firm conclusion with respect to lycopene supplementation in prostate cancer patients and larger RCTs are required in broader patient groups.

Abstract
The medical field has undergone a quiet revolution during the past three decades. Patients have been brought into the treatment decision process as never before. Gone are the days when the patient was delivered the diagnosis and simply told how their disorder was to be treated. Rather, widespread use of shared decision making has changed the way that patients and their physicians interact. The development of best clinical practices from concepts of evidence-based medicine has shown that, for many disorders, the various treatment options result in near-equivalent outcomes. More recently, the democratization of medical information by the internet has made the patient a much better informed consumer, and thus a more active participant in his or her own care.

Abstract
OBJECTIVES To create physician awareness of complementary and alternative medicine therapy use in patients with prostate cancer so that physicians can monitor for adverse events. Approximately one fourth to one third of patients diagnosed with prostate cancer reported complementary and alternative medicine use, and many of these patients are taking a supplement called "Dr. Donsbach's Prostasol." METHODS We discuss the cases of 2 patients with prostate cancer who were taking Dr. Donsbach's Prostasol and developed venous thromboembolic events while taking this supplement, in the absence of other obvious risk factors. We review these 2 cases and the time-line for the development of the venous thromboembolic events and use of Dr. Donsbach's Prostasol. We compared Prostasol with PC-SPES, a similar supplement that was associated with thrombosis and was ultimately taken off the market because of patient safety concerns. RESULTS Prostasol contains phytoestrogens that could result in both the suppression of testosterone and the predisposition to thrombosis. Both patients had suppression of their testosterone to castrate levels with an associated decrease in prostate-specific antigen at the time of their thrombotic event. CONCLUSIONS These cases are suggestive of an association between Prostasol use and venous thromboembolic events. Physicians should be aware of the use of this agent in their patients, although it is not known whether it would be appropriate to prescribe prophylactic low-dose warfarin therapy. If possible, additional study of complementary and alternative medicine therapies for safety and efficacy are indicated.

Abstract
PURPOSE/OBJECTIVES To explore the cancer symptom experience, self-care strategies, and quality of life (QOL) among Chinese Americans during outpatient chemotherapy. DESIGN Descriptive, exploratory cohort study. SETTING An outpatient infusion unit at a public urban county medical center. SAMPLE 25 Chinese-speaking patients with cancer completed the study. Participants were first-generation immigrants with low levels of acculturation; 88% could not read English; 64% had an annual household income of less than $20,000. METHODS Participants completed a basic demographics data sheet, the Suinn-Lew Acculturation Scale, the Memorial Symptom Assessment Scale and Self-Care Diary weekly for three weeks, and the Multidimensional QOL Scale-Cancer and Short-Form 36 Health Survey at the start and end of one chemotherapy cycle. Study instruments were translated into Chinese. MAIN RESEARCH VARIABLES Symptoms, self-care, QOL, and acculturation. FINDINGS Participants reported experiencing about 14 symptoms weekly. Lack of energy, hair loss, dry mouth, sleep difficulty, and loss of appetite were reported most frequently. On average, about two self-care strategies per symptom were reported and were low to moderate in effectiveness. About 20% of the sample listed Chinese medicine as part of their self-care strategies. A moderate level of QOL was reported. CONCLUSIONS Using translated standardized questionnaires can be a feasible method of data collection in studies with non-English-speaking patients. However, having well-trained, bilingual data collectors is important. More attention to long-term cancer self-management in minority patients with cancer is needed. IMPLICATIONS FOR NURSING Further research is needed with larger samples, more efficient community-based recruitment strategies, and the development and testing of culturally sensitive interventions.

Abstract
Vitamin and mineral supplement use is thought to be common among the 10 million adults in the United States who have been diagnosed with cancer; however, well-conducted studies of this topic are sparse. Moreover, the biologic effects of supplement use among cancer survivors are not well established and not necessarily beneficial. We present a systematic summary of studies published between 1999 and 2006, 32 in total, addressing vitamin and mineral supplement use among US adult cancer patients and survivors. Supplement use is widespread among cancer patients and longer-term survivors. In studies combining different cancer sites, 64% to 81% of survivors reported using any vitamin or mineral supplements and 26% to 77% reported using any multivitamins. In contrast, approximately 50% of US adults use dietary supplements and 33% use multivitamin/multimineral supplements. Between 14% and 32% of survivors initiate supplement use after diagnosis, and use differs by cancer site. Breast cancer survivors reported the highest use, whereas prostate cancer survivors reported the least. Higher level of education and female sex emerged as factors most consistently associated with supplement use. Up to 68% of physicians are unaware of supplement use among their cancer patients. These results highlight the need for further studies of the association between dietary supplement use and cancer treatment toxicity, recurrence, survival, and quality of life to support evidence-based clinical guidelines for dietary supplement use among cancer patients and longer-term survivors.
