Outcome-expectation beliefs and knowledge may ultimately influence behavior for cancer prevention. The aims of this study were to measure changes in knowledge and beliefs about cancer prevention before and after viewing a television advertisement and identify the factors affecting receptivity to its messages. A one-group pretest-posttest design was used in this study of 1,000 individuals aged 20 to 65 years who were recruited online in November 2014. The outcome variables included cancer prevention beliefs based on the Health Belief Model (five items) and knowledge about risk factors for cancer (seven items). Perceived susceptibility, perceived benefits, and self-efficacy increased significantly and their perceived severity and perceived barriers decreased significantly, after participants viewed the television advertisement. Correct responses to questions about risk factors also increased significantly, except for smoking. The main factors affecting changes in the outcome variables were age, interest in cancer prevention, social network, satisfaction with the ad, and pretest scores. Television advertisements with positive frameworks can be an efficient channel of improving beliefs and knowledge about cancer prevention in a short period. The continuous development of intervention materials that consider the demographics, needs, and satisfaction of the target group will be necessary for future studies.

Background: Skin cancer is a serious public health problem in the world. Its prevalence in many countries has been increased in recent years. This study aimed to assess the effects of a theory-based educational intervention to promote skin cancer preventive behaviors (SCPBs) among rural farmers in Chalderan County, Iran. Methods: This was a quasi-randomized controlled field trial study conducted on 238 rural farmers. The data were collected by a questionnaire containing the constructs of the Protection Motivation Theory (PMT) as well as the items of SCPBs. The differences between the groups before and 3 months after the intervention were determined by independent t-test, paired t-test, and chi-square applying SPSS software. Results: Before the intervention, no significant difference was found in the scores of the PMT constructs between the two groups (p>0.05). However, significant differences were found between the scores of all the variables, as well as SCPBs, in the two groups after the intervention (p<0.05). Conclusion: The PMT was found to be an appropriate framework for designing educational interventions aiming at promoting SCPBs among rural farmers. It was concluded that designing an educational program with a focus on promoting perceived susceptibility increased the level of performing SCPBs among the rural farmers.

Activator protein 1 (AP-1) is a key transcription factor in the control of several cellular processes responsible for cell survival proliferation and differentiation. Dysfunctional AP-1 expression and activity are involved in several severe diseases, especially inflammatory disorders and cancer. Therefore, targeting AP-1 has recently emerged as an attractive therapeutic strategy for cancer prevention and therapy. This review summarizes our current understanding of AP-1 biology and function as well as explores and discusses several natural bioactive compounds modulating AP-1-associated signaling pathways for cancer prevention and intervention. Current limitations, challenges, and future directions of research are also critically discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

The dramatic increase in breast cancer incidence compels a paradigm shift in our preventive efforts. There are several barriers to overcome before prevention becomes an established part of breast cancer management. The objective of this review is to identify the clinical challenges for improved breast cancer prevention and discuss current knowledge on breast cancer risk assessment methods, risk communication, ethics, and interventional efforts with the aim of covering the aspects relevant for a breast cancer prevention trial. Herein, the following five areas are discussed: (i) Adequate tools for identification of women at high risk of breast cancer suggestively entitled Prevent! Online. (ii) Consensus on the definition of high risk, which is regarded as mandatory for all risk communication and potential prophylactic interventions. (iii) Risk perception and communication regarding risk information. (iv) Potential ethical concerns relevant for future breast cancer prevention programs. (v) Risk-reducing programs involving multileveled prevention depending on identified risk. Taken together, devoted efforts from both policy makers and health care providers are warranted to improve risk assessment and risk counseling in women at risk for breast cancer to optimize the prevention of breast cancer.

Rapid developments in technology have encouraged the use of mobile phones in smoking cessation, promoting healthy diet, nutrition, and physical activity, sun safety, and cancer screening. Although many apps relating to the prevention of cancer and other chronic diseases are available from major mobile phone platforms, relatively few have been tested in research studies to determine their efficacy. In this paper, we discuss issues related to the development and testing of new apps for preventing cancer through smoking cessation, sun safety, and other healthy behaviors, including key methodologic issues and outstanding challenges. An exploratory literature review was conducted using bibliographic searches in PubMed and CINAHL with relevant search terms (eg, smartphones, smoking cessation, cancer prevention, cancer screening, and carcinogens) to identify papers published in English through October 2015. Only 4 randomized controlled trials of the use of mobile phone apps for smoking cessation and 2 trials of apps for sun safety were identified, indicating that it is premature to conduct a systematic search and meta-analysis of the published literature on this topic. Future studies should utilize randomized controlled trial research designs, larger sample sizes, and longer study periods to better establish the cancer prevention and control capabilities of mobile phone apps. In developing new and refined apps for cancer prevention and control, both health literacy and eHealth literacy should be taken into account. There is a need for culturally appropriate, tailored health messages to increase knowledge and awareness of health behaviors such as smoking cessation, cancer screening, and sun safety. Mobile phone apps are likely to be a useful and low-cost intervention for preventing cancer through behavioral changes.

To examine the impact of a skin cancer prevention intervention that promoted sunless tanning as a substitute for sunbathing. Randomized controlled trial. Public beaches in Massachusetts. Women (N = 250) were recruited to participate in the study during their visit to a public beach. Intervention The intervention included motivational messages to use sunless tanning as an alternative to UV tanning, instructions for proper use of sunless tanning products, attractive images of women with sunless tans, a free trial of a sunless tanning product, skin cancer education, and UV imaging. The control participants completed surveys. The primary outcome was sunbathing 2 months and 1 year after the intervention. Secondary outcomes included sunburns, sun protection use, and sunless tanning. At 2 months, intervention participants reduced their sunbathing significantly more than did controls and reported significantly fewer sunburns and greater use of protective clothing. At 1 year, intervention participants reported significant decreases in sunbathing and increases in sunless tanning relative to control participants but no differences in the other outcomes. This intervention, which promoted sunless tanning as an alternative to UV tanning, had a short-term effect on sunbathing, sunburns, and use of protective clothing and a longer-term effect on sunbathing and sunless tanning. clinicaltrials.gov Identifier: NCT00403377.

The cancer-preventive activity of vitamin E has been studied. Whereas some epidemiological studies have suggested a protective effect of vitamin E against cancer formation, many large-scale intervention studies with alpha-tocopherol (usually large doses) have not demonstrated a cancer-preventive effect. Studies on alpha-tocopherol in animal models also have not demonstrated robust cancer prevention effects. One possible explanation for the lack of demonstrable cancer-preventive effects is that high doses of alpha-tocopherol decrease the blood and tissue levels of delta-tocopherols. It has been suggested that gamma-tocopherol, due to its strong anti-inflammatory and other activities, may be the more effective form of vitamin E in cancer prevention. Our recent results have demonstrated that a gamma-tocopherol-rich mixture of tocopherols inhibits colon, prostate, mammary and lung tumorigenesis in animal models, suggesting that this mixture may have a high potential for applications in the prevention of human cancer. In this review, we discuss biochemical properties of tocopherols, results of possible cancer-preventive effects in humans and animal models and possible mechanisms involved in the inhibition of carcinogenesis. Based on this information, we propose that a gamma-tocopherol-rich mixture of tocopherols is a very promising cancer-preventive agent and warrants extensive future research.

Among the known risk factors, smoking is clearly related to the incidence of lung cancer and alcohol consumption is to breast cancer. In this manuscript we modelled the potential benefits of reductions in smoking or alcohol prevalence for the burden of these cancers. We used Prevent v.3.01 to assess the changes in incidence as a result of risk factor changes. Incidence of lung and breast cancer until 2050 was predicted under two scenarios: ideal (total elimination of smoking and reduction of alcohol intake to maximum 1 units/d for women) and optimistic (decreasing prevalence of risk factors because of a 10% increase in cigarette and alcohol beverage price, repeated every 5 years). Danish data from the household surveys, cancer registration and Eurostat were used. Up to 49% less new lung cancer cases can be expected in 2050 if smoking were to be completely eliminated. Five-yearly 10% price increases may prevent 521 new lung cancer cases in 2050 (21% less cases). An intervention that immediately reduces population alcohol consumption to the recommended level (below 12 g/d) may lower breast cancer by 7%, preventing 445 out of the 6060 expected new cases in 2050. Five-yearly 10% price increases in alcoholic beverages achieved a reduction of half as expected by the ideal scenario, i.e. 4% (262) preventable cases in 2050. The future burden of lung and breast cancer could be markedly reduced by intervening in their risk factors. Prevent illustrates the benefit of interventions and may serve as guidance in political decision-making. Copyright © 2010 Elsevier Ltd. All rights reserved.

Early Nutrition and Physical Activity Interventions in Childhood Cancer Survivors.

Zhang, Fang Fang; Kelly, Michael J; Must, Aviva

2017-06-01

Childhood cancer survivors experience excessive weight gain early in treatment. Lifestyle interventions need to be initiated early in cancer care to prevent the early onset of obesity and cardiovascular disease (CVD). We reviewed the existing literature on early lifestyle interventions in childhood cancer survivors and consider implications for clinical care. Few lifestyle interventions focus on improving nutrition in childhood cancer survivors. A consistent effect on reducing obesity and CVD risk factors is not evident from the limited number of studies with heterogeneous intervention characteristics, although interventions with a longer duration and follow-up show more promising trends. Future lifestyle interventions should be of a longer duration and include a nutrition component. Interventions with a longer duration and follow-up are needed to assess the timing and sustainability of the intervention effect. Lifestyle interventions introduced early in cancer care are both safe and feasible.

One third of cancer deaths are attributable to modifiable lifestyle, behaviour and psychosocial risk factors. Psycho-oncology can contribute significantly to prevention initiatives such as those described in national cancer control plans (NCCPs), to reduce or eliminate these risk factors. However, the extent to which psycho-oncology expertise has informed prevention objectives in plans is unclear. Accordingly, 35 English language NCCPs were located via existing databases and were searched using Adobe text searches ('psycho', 'social', 'behav' and 'intervention') to identify (a) representations of psycho-oncology, its dimensions (psychological, social and behavioural) and roles (e.g. psychologist); and (b) behaviour/lifestyle change interventions. A third of NCCPs included the term psycho- or psychosocial-oncology; approximately half referred to a psycho-oncology dimension regarding prevention and early detection and half included actions/objectives relating to health professionals and provision of psychosocial care. The majority of cancer plans included prevention outcomes and focussed primarily on smoking cessation and alcohol reduction. Interventions commonly proposed were education, regulation and service provision; however, many were aspirational statements of intent rather than specific interventions. Psycho-oncology was represented in NCCPs but was limited in reference to prevention with few behavioural interventions utilised. Psycho-oncology input is needed to prescribe evidence-based interventions in cancer plans that not only educate, regulate and provide resources but also motivate, empower and create a supportive normative environment for behaviour change. In this manuscript, and throughout this Special Issue on Cancer Prevention, important principles, ideas and evidence within psycho-oncology are outlined which, if properly implemented, can help reduce the global cancer burden.

Developments in breast cancer treatment have resulted in reduction in breast cancer mortality in the developed world. However incidence continues to rise and greater use of preventive interventions including the use of therapeutic agents is needed to control this burden. High quality evidence from 9 major trials involving more than 83000 participants shows that selective oestrogen receptor modulators (SERMs) reduce breast cancer incidence by 38%. Combined results from 2 large trials with 8424 participants show that aromatase inhibitors (AIs) reduce breast cancer incidence by 53%. These benefits are restricted to prevention of ER positive breast cancers. Restricting preventive therapy to high-risk women improves the benefit-harm balance and many guidelines now encourage healthcare professionals to discuss preventive therapy in these women. Further research is needed to improve our risk-prediction models for the identification of high risk women for preventive therapy with greater accuracy and to develop surrogate biomarkers of response. Long-term follow-up of the IBIS-I trial has provided valuable insights into the durability of benefits from preventive therapy, and underscores the need for such follow up to fully evaluate other agents. Full utilisation of preventive therapy also requires greater knowledge and awareness among both doctors and patients about benefits, harms and risk factors. Healthcare professionals should routinely discuss preventive therapy with women at high-risk of breast cancer. Copyright © 2017 Elsevier Ltd. All rights reserved.

The aim of this study was to evaluate the effects of an educational intervention on breast self-examination, cancer prevention-related knowledge, practices, and behavior change in scholars from a low-income area in Bogota, Colombia. Uncontrolled trial was conducted in 155 scholars. Two educational sessions, 90 min each, were carried out in March 2015 according to the Colombian guidelines for educational communication in the framework of cancer control. All participants completed a self-reported questionnaire at pre- and post-intervention, as well as 1, 3, and 6 months after the intervention. Breast self-examination was practiced by 78.1% of the scholars, and the overall knowledge of breast cancer risk factors was poor. The educational intervention resulted in significant improvements on breast self-examination practice, the knowledge of the technique, and the knowledge of the main risk factors for breast cancer as well as the practice of physical activity and vegetable intake at 6 months follow-up. An educational intervention according to the Colombian guidelines for educational communication in the framework of cancer control improved the practice of breast self-examination, cancer prevention-related knowledge, as well as the practice of physical activity and vegetable consumption in scholars from a low-income area in Bogota, Colombia. Further randomized controlled studies are warranted.

Epigenetic biomarkers, such as DNA methylation, can increase cancer risk through altering gene expression. The Cancer Genome Atlas (TCGA) Network has demonstrated breast cancer-specific DNA methylation signatures. DNA methylation signatures measured at the time of diagnosis may prove important for treatment options and in predicting disease-free and overall survival (tertiary prevention). DNA methylation measurement in cell free DNA may also be useful in improving early detection by measuring tumor DNA released into the blood (secondary prevention). Most evidence evaluating the use of DNA methylation markers in tertiary and secondary prevention efforts for breast cancer comes from studies that are cross-sectional or retrospective with limited corresponding epidemiologic data, raising concerns about temporality. Few prospective studies exist that are large enough to address whether DNA methylation markers add to the prediction of tertiary and secondary outcomes over and beyond standard clinical measures. Determining the role of epigenetic biomarkers in primary prevention can help in identifying modifiable pathways for targeting interventions and reducing disease incidence. The potential is great for DNA methylation markers to improve cancer outcomes across the prevention continuum. Large, prospective epidemiological studies will provide essential evidence of the overall utility of adding these markers to primary prevention efforts, screening, and clinical care.

National colorectal cancer (CRC) screening rates have plateaued. To optimize interventions targeting those unscreened, a better understanding is needed of how this preventive service fits in with multiple preventive and chronic care needs managed by primary care providers (PCPs). This study examines whether PCP practices of other preventive and chronic care needs correlate with CRC screening. We performed a retrospective cohort study of 90 PCPs and 33,137 CRC screening-eligible patients. Five PCP quality metrics (breast cancer screening, cervical cancer screening, HgbA1c and LDL testing, and blood pressure control) were measured. A baseline correlation test was performed between these metrics and PCP CRC screening rates. Multivariable logistic regression with clustering at the clinic-level estimated odds ratios and 95% confidence intervals for these PCP quality metrics, patient and PCP characteristics, and their relationship to CRC screening. PCP CRC screening rates have a strong correlation with breast cancer screening rates (r = 0.7414, p < 0.001) and a weak correlation with the other quality metrics. In the final adjusted model, the only PCP quality metric that significantly predicted CRC screening was breast cancer screening (OR 1.25; 95% CI 1.11-1.42; p < 0.001). PCP CRC screening rates are highly concordant with breast cancer screening. CRC screening is weakly concordant with cervical cancer screening and chronic disease management metrics. Efforts targeting PCPs to increase CRC screening rates could be bundled with breast cancer screening improvement interventions to increase their impact and success.

Cultural Effects on Cancer Prevention Behaviors: Fatalistic Cancer Beliefs and Risk Optimism Among Asians in Singapore.

2017-10-01

Although culture is acknowledged as an important factor that influences health, little is known about cultural differences pertaining to cancer-related beliefs and prevention behaviors. This study examines two culturally influenced beliefs-fatalistic beliefs about cancer prevention, and optimistic beliefs about cancer risk-to identify reasons for cultural disparity in the engagement of cancer prevention behaviors. We utilized data from national surveys of European Americans in the United States (Health Information National Trends Survey 4, Cycle3; N = 1,139) and Asians in Singapore (N = 1,200) to make cultural comparisons. The odds of an Asian adhering to prevention recommendations were less than half the odds of a European American, with the exception of smoking avoidance. Compared to European Americans, Asians were more optimistic about their cancer risk both in an absolute and a comparative sense, and held stronger fatalistic beliefs about cancer prevention. Mediation analyses revealed that fatalistic beliefs and absolute risk optimism among Asians partially explain their lower engagement in prevention behaviors, whereas comparative risk optimism increases their likelihood of adhering to prevention behaviors. Our findings underscore the need for developing culturally targeted interventions in communicating cancer causes and prevention.

To evaluate the robustness of an appearance-focused intervention to prevent skin cancer in individuals reporting seasonal affective disorder (SAD) symptoms and pathological tanning motives. Randomized, controlled clinical trial. College campus. Four hundred thirty adult female indoor tanners (200 in the intervention group and 230 control participants). A booklet discussing the history of tanning, current tanning norms, UV radiation's effects on skin, recommendations for indoor tanning use focusing on abstinence and harm reduction recommendations, and information on healthier, appearance-enhancing alternatives to tanning. Self-reported attitudes, intentions, and tanning behaviors; pathological tanning motives assessed by a questionnaire developed for this study; and SAD symptoms assessed by the Seasonal Pattern Assessment Questionnaire. Two of the 4 pathological tanning scales, opiatelike reactions to tanning and dissatisfaction with natural skin tone, were significant moderators demonstrating stronger treatment effects for individuals scoring higher on these scales. Treatment effects were equivalently positive (ie, no significant moderator effects) for all levels of SAD symptoms and all levels of the other 2 pathological tanning motive scales (ie, perceiving tanning as a problem and tolerance to the effects of tanning). The appearance-focused skin cancer prevention intervention is robust enough to reduce indoor tanning among tanners who exhibit SAD symptoms or pathological tanning motives. Tailored interventions may address individuals' motivations for tanning and their relation to maladaptive behavior, such as dissatisfaction with appearance or the need for relaxation because of anxiety.

The Prostate Cancer Prevention Trial was the first clinical trial to show that a direct intervention (5 mg of finasteride daily for 7 years) could reduce a man's risk of developing prostate cancer. Initial results also suggested that men taking finasteride had an increased risk of developing what appeared to be higher-grade disease (Gleason score 7-10). The National Cancer Institute has a congressional mandate to communicate health information to the public and has established methods to reach the public directly and to reach information intermediaries in the media, professional societies, and advocacy groups. The groundbreaking yet complicated results of the Prostate Cancer Prevention Trial were widely disseminated by National Cancer Institute using the social marketing and public-relations strategies and tactics detailed here.

The study evaluates the effectiveness of an ongoing, community-based breast cancer prevention program offered by a local social services agency in the Washington, DC, metropolitan area. Korean American women who participated in this breast cancer prevention program were compared with those who did not participate in their knowledge, attitude, and screening behaviors. The study found that the intervention group was more knowledgeable on breast cancer and related services and reported more positive attitudes toward breast cancer screening services than the comparison group. The participants in the intervention group were also more likely to plan to receive a mammogram than those in the comparison group. However, significant differences were not observed in the two groups in their intention to receive a clinical breast examination. The study findings suggest that an ongoing, community-based breast cancer prevention program can be an effective method of addressing breast cancer prevention disparities observed among Korean American women.

Health initiatives for the prevention of skin cancer.

2014-01-01

Skin cancer is the most frequent type of cancer in white population worldwide. However, because the most prominent risk factor-solar UV-radiation and/or artificial UV from sunbeds-is known, skin cancer is highly preventable be primary prevention. This prevention needs, that the public is informed by simple and balanced messages about the possible harms and benefits of UV-exposure and how a person should behave under certain conditions of UV-exposure. For this purpose information and recommendations for the public must be age- and target-group specific to cover all periods of life and to reach all sub-groups of a population, continuously. There is a need that political institutions together with Health Institutions and Societies (e.g., European Commission, WHO, EUROSKIN, ICNIRP, etc.), which are responsible for primary prevention of skin cancer, find a common language to inform the public, in order not to confuse it. This is especially important in connection with the ongoing Vitamin D debate, where possible positive effects of UV have to be balanced with the well known skin cancer risk of UV. A continuously ongoing evaluation of interventions and programs in primary prevention is a pre-requisite to assess the effectiveness of strategies. There is surely no "no message fits all" approach, but balanced information in health initiatives for prevention of skin cancer, which use evidence-base strategies, will further be needed in the future to reduce the incidence, morbidity and mortality skin cancer.

The objectives of this study are to assess undergraduate awareness of cancer risk factors, prevention strategies, and warning signs and to evaluate whether an educational intervention increases cancer awareness. This study adopts a nonequivalent control group pretest-posttest design. Of the 386 students who completed the pretest, only 35-39 % identified low fruit and vegetable intake, being overweight, and physical inactivity as cancer risk factors, and cancer warning signs. After the educational intervention, the analysis of variance of changes from baseline (the pretest score) for all four experimental groups were all significantly higher than those of the two control groups (p ≤.001), except for the change of the retention test score from the pretest score for experimental group 3. This study highlights the need to improve undergraduates' cancer awareness and the effectiveness of educational intervention.

Historically, cancer has occurred at a lower rate in aboriginal populations; however, it is now dramatically increasing. Unless preventive measures are taken, cancer rates among aboriginal peoples are expected to soon surpass those in non-aboriginal populations. Because a large proportion of malignant disorders are preventable, primary prevention through socioeconomic interventions, environmental changes, and lifestyle modification might provide the best option for reducing the increasing bur...

The Allium genus includes garlic, onions, shallots, leeks, and chives. These vegetables are popular in cuisines worldwide and are valued for their potential medicinal properties. Epidemiological studies, while limited in their abilities to assess Allium consumption, indicate some associations of Allium vegetable consumption with decreased risk of cancer, particularly cancers of the gastrointestinal tract. Limited intervention studies have been conducted to support these associations. The majority of supportive evidence on Allium vegetables cancer preventive effects comes from mechanistic studies. These studies highlight potential mechanisms of individual sulfur-containing compounds and of various preparations and extracts of these vegetables, including decreased bioactivation of carcinogens, antimicrobial activities, and redox modification. Allium vegetables and their components have effects at each stage of carcinogenesis and affect many biological processes that modify cancer risk. This review discusses the cancer preventive effects of Allium vegetables, particularly garlic and onions, and their bioactive sulfur compounds and highlights research gaps. PMID:25586902

The step-wise development of colorectal neoplasia from adenoma to carcinoma suggests that specific interventions could delay or prevent the development of invasive cancer. Several key factors involved in colorectal cancer pathogenesis have already been identified including cyclooxygenase 2 (COX-2), nuclear factor kappa B (NF-κB), survivin and insulin-like growth factor-I (IGF-I). Clinical trials of COX-2 inhibitors have provided the "proof of principle" that inhibition of this enzyme can prevent the formation of colonic adenomas and potentially carcinomas, however concerns regarding the potential toxicity of these drugs have limited their use as a chemopreventative strategy. Curcumin, resveratrol and quercetin are chemopreventive agents that are able to suppress multiple signaling pathways involved in carcinogenesis and hence are attractive candidates for further research.

Nanotechnology is emerging as a promising modality for cancer treatment; however, in the realm of cancer prevention, its full utility has yet to be determined. Here, we discuss the potential of integrating nanotechnology in cancer prevention to augment early diagnosis, precision targeting, and controlled release of chemopreventive agents, reduced toxicity, risk/response assessment, and personalized point-of-care monitoring. Cancer is a multistep, progressive disease; the functional and acquired characteristics of the early precancer phenotype are intrinsically different from those of a more advanced anaplastic or invasive malignancy. Therefore, applying nanotechnology to precancers is likely to be far more challenging than applying it to established disease. Frank cancers are more readily identifiable through imaging and biomarker and histopathologic assessment than their precancerous precursors. In addition, prevention subjects routinely have more rigorous intervention criteria than therapy subjects. Any nanopreventive agent developed to prevent sporadic cancers found in the general population must exhibit a very low risk of serious side effects. In contrast, a greater risk of side effects might be more acceptable in subjects at high risk for cancer. Using nanotechnology to prevent cancer is an aspirational goal, but clearly identifying the intermediate objectives and potential barriers is an essential first step in this exciting journey. ©2014 American Association for Cancer Research.

Backgrounds. The aim of this study was to describe the preventive behaviors of industrial workers and factors influencing occupational cancer prevention behaviors using protection motivation theory. Methods. A self-administered questionnaire was completed by 161 petrochemical workers in Iran in 2014 which consisted of three sections: background information, protection motivation theory measures, and occupational cancers preventive behaviors. Results. A statistically significant positive correlation was found between PM and self-efficacy, response efficacy, and the cancer preventive behaviors. Meanwhile, statistically significant negative correlations were found between PM, cost, and reward. Conclusions. Among available PMT constructs, only self-efficacy and cost were significant predictors of preventive behaviors. Protection motivation model based health promotion interventions with focus on self-efficacy and cost would be desirable in the case of occupational cancers prevention.

Occurring from ultraviolet radiation combined with impairing ozone levels, uncritical sun exposure and use of tanning beds an increasing number of people are affected by different types of skin cancer. But preventive interventions like skin cancer screening are still missing the evidence for effectiveness and therefore are criticised. Fundamental for an appropriate course of action is to approach the defined parameters as measures for effectiveness critically. A prerequisite should be the critical application of used parameter that are defined as measures for effectiveness. This research seeks to establish, through the available literature, the effects and conditions that prove the effectiveness of prevention strategies in skin cancer. A mixed-method approach is employed to combine quantitative to qualitative methods and answer what effects can display effectiveness considering time horizon, perspective and organisational level and what are essential and sufficient conditions to prove effectiveness and cost-effectiveness in skin cancer prevention strategies. A systematic review will be performed to spot studies from any design and assess the data quantitatively and qualitatively. Included studies from each key question will be summarised by characteristics like population, intervention, comparison, outcomes, study design, endpoints, effect estimator and so on. Beside statistical relevancies for a systematic review the qualitative method of qualitative comparative analysis (QCA) will be performed. The estimated outcomes from this review and QCA are the accomplishment and absence of effects that are appropriate for application in effectiveness assessments and further cost-effectiveness assessment. Formal ethical approval is not required as primary data will not be collected.

Cervical cancer is a preventable disease which causes significant morbidity and mortality, particularly in developing countries. Although technology for early detection continues to improve, prevention programs suffer from significant barriers. Community-based participatory research is an approach to research which focuses on collaboration with the community to surmount these barriers. The objective of this study was to evaluate the utility of community-based participatory research techniques in a mother-child screen/treat and vaccinate program for cervical cancer prevention in Manchay, Peru. Human papillomavirus (HPV) self-sampling and cryotherapy were used for the screen/treat intervention, and the Gardasil vaccine was used for the vaccine intervention. Community health workers from Manchay participated in a 3-day educational course, designed by the research team. The community health workers then decided how to implement the interventions in their community. The success of the program was measured by (1) the ability of the community health workers to determine an implementation plan, (2) the successful use of research forms provided, (3) participation and retention rates, and (4) satisfaction of the participants. (1) The community health workers used a door-to-door approach through which participants were successfully registered and both interventions were successfully carried out; (2) registration forms, consent forms, and result forms were used correctly with minimal error; (3) screen/treat intervention: 97% of registered participants gave an HPV sample, 94% of HPV-positive women were treated, and 90% returned for 6-month follow-up; vaccine intervention: 95% of registered girls received the first vaccine, 97% of those received the second vaccine, and 93% the third; (4) 96% of participants in the screen/treat intervention reported high satisfaction. Community-based participatory research techniques successfully helped to implement a screen/treat and vaccinate

Full Text Available Despite declines in cervical cancer mortality in developed countries, cervical cancer incidence and mortality rates remain high in Jamaica due to low levels of screening. Effective interventions are needed to decrease barriers to preventive behaviors and increase adoption of behaviors and services to improve prospects of survival. We enrolled 225 women attending health facilities in an intervention consisting of a pre-test, educational presentation and post-test. The questionnaires assessed attitudes, knowledge, risk factors, and symptoms of cervical cancer among women. Changes in knowledge and intention to screen were assessed using paired t-tests and tests for correlated proportions. Participants were followed approximately six months post-intervention to determine cervical cancer screening rates. We found statistically significant increases from pre-test to post-test in the percentage of questions correctly answered and in participants’ intention to screen for cervical cancer. The greatest improvements were observed in responses to questions on knowledge, symptoms and prevention, with some items increasing up to 62% from pre-test to post-test. Of the 123 women reached for follow-up, 50 (40.7% screened for cervical cancer. This theory-based education intervention significantly increased knowledge of and intention to screen for cervical cancer, and may be replicated in similar settings to promote awareness and increase screening rates.

Preventative therapies for healthy women at high risk of breast cancer

International Nuclear Information System (INIS)

Sestak, Ivana

2014-01-01

Tamoxifen has been shown to reduce the risk of developing estrogen receptor (ER)-positive breast cancer by at least 50%, in both pre- and postmenopausal women. The current challenge is to find new agents with fewer side effects and to find agents that are specifically suitable for premenopausal women with ER-negative breast cancer. Other selective estrogen receptor modulators (SERMs), such as raloxifene, arzoxifene, and lasofoxifene, have been shown to reduce the incidence of breast cancer by 50%–80%. SERMs are interesting agents for the prevention of breast cancer, but longer follow-up is needed for some of them for a complete risk–benefit profile of these drugs. Aromatase inhibitors have emerged as new drugs in the prevention setting for postmenopausal women. In the Mammary Prevention 3 (MAP3) trial, a 65% reduction in invasive breast cancer with exemestane was observed, and the Breast Cancer Intervention Study-II trial, which compared anastrozole with placebo, reported a 60% reduction in those cancers. Although SERMs and aromatase inhibitors have been proven to be excellent agents in the preventive setting specifically for postmenopausal women and ER-positive breast cancer, newer agents have to be found specifically for ER-negative breast cancers, which mostly occur in premenopausal women

Background This review is an update of the first Cochrane publication on selenium for preventing cancer (Dennert 2011). Selenium is a metalloid with both nutritional and toxicological properties. Higher selenium exposure and selenium supplements have been suggested to protect against several types of cancers. Objectives Two research questions were addressed in this review: What is the evidence for: an aetiological relation between selenium exposure and cancer risk in humans? andthe efficacy of selenium supplementation for cancer prevention in humans? Search methods We conducted electronic searches of the Cochrane Central Register of Controlled Trials (CENTRAL, 2013, Issue 1), MEDLINE (Ovid, 1966 to February 2013 week 1), EMBASE (1980 to 2013 week 6), CancerLit (February 2004) and CCMed (February 2011). As MEDLINE now includes the journals indexed in CancerLit, no further searches were conducted in this database after 2004. Selection criteria We included prospective observational studies (cohort studies including sub-cohort controlled studies and nested case-control studies) and randomised controlled trials (RCTs) with healthy adult participants (18 years of age and older). Data collection and analysis For observational studies, we conducted random effects meta-analyses when five or more studies were retrieved for a specific outcome. For RCTs, we performed random effects meta-analyses when two or more studies were available. The risk of bias in observational studies was assessed using forms adapted from the Newcastle-Ottawa Quality Assessment Scale for cohort and case-control studies; the criteria specified in the Cochrane Handbook for Systematic Reviews of Interventions were used to evaluate the risk of bias in RCTs. Main results We included 55 prospective observational studies (including more than 1,100,000 participants) and eight RCTs (with a total of 44,743 participants). For the observational studies, we found lower cancer incidence (summary odds ratio (OR) 0

African-American men have the highest prostate cancer rates worldwide, and innovative efforts are needed to increase cancer prevention and screening behaviors among this population. Formative research was conducted to assess attitudes and behaviors linked to prostate cancer prevention activities that could be used to develop a culturally relevant intervention for an African-American church-based population. Four gender-specific focus groups were conducted with 29 men and women at two African-American churches in central North Carolina. Three primary themes emerged from the focus group discussions: culturally and gender-influenced beliefs and barriers about cancer prevention and screening; barriers related to the healthcare system: and religious influences, including the importance of spiritual beliefs and church support. These discussions revealed the importance of the black family, the positive influence of spouses/partners on promoting cancer screening and healthy behaviors, the roles of faith and church leadership, and beliefs about God's will for good health. These findings also revealed that there are still major barriers and challenges to cancer prevention among African Americans, including continued mistrust of the medical community and negative attitudes toward specific screening tests. Findings provide important insights to consider in implementing successful prostate cancer prevention interventions designed for church-based audiences.

Despite high-quality evidence demonstrating that screening reduces mortality from breast, cervical, colorectal, and lung cancers, a substantial portion of the population remains inadequately screened. There is a critical need to identify interventions that increase the uptake and adoption of evidence-based screening guidelines for preventable cancers at the community practice level. Text messaging (short message service, SMS) has been effective in promoting behavioral change in various clinical settings, but the overall impact and reach of text messaging interventions on cancer screening are unknown. The objective of this systematic review was to assess the effect of text messaging interventions on screening for breast, cervical, colorectal, and lung cancers. We searched multiple databases for studies published between the years 2000 and 2017, including PubMed, EMBASE, and the Cochrane Library, to identify controlled trials that measured the effect of text messaging on screening for breast, cervical, colorectal, or lung cancers. Study quality was evaluated using the Cochrane risk of bias tool. Our search yielded 2238 citations, of which 31 underwent full review and 9 met inclusion criteria. Five studies examined screening for breast cancer, one for cervical cancer, and three for colorectal cancer. No studies were found for lung cancer screening. Absolute screening rates for individuals who received text message interventions were 0.6% to 15.0% higher than for controls. Unadjusted relative screening rates for text message recipients were 4% to 63% higher compared with controls. Text messaging interventions appear to moderately increase screening rates for breast and cervical cancer and may have a small effect on colorectal cancer screening. Benefit was observed in various countries, including resource-poor and non-English-speaking populations. Given the paucity of data, additional research is needed to better quantify the effectiveness of this promising intervention

Radiation oxidative stress in cancer induction and prevention

International Nuclear Information System (INIS)

Meher, Prabodha Kumar; Mishra, Kaushala Prasad

2017-01-01

Exposure of cells to ionizing radiation causes generation of intracellular reactive oxygen species (ROS) which are implicated in the mechanism of carcinogenesis. Molecular steps involved in the transformation of normal cells to cancer cells have been enigmatic but generally believed to arise from aberration in cellular redox homeostasis. In normal cell function, a delicate balance is maintained between ROS generated in the metabolic process and level of endogenous antioxidant defense. ROS are known to regulate various cellular functions, such as cell division, signal transduction, and apoptosis. Cells experience oxidative stress when excess production of ROS occurs inside a cell upon exposure to external stress or agents. This redox imbalance affects the cellular functions due to DNA strand breaks, chromosomal aberrations, gene mutations, alteration in signal transduction, and inhibition of apoptosis leading to induction of cancer and other diseases. Radiation-induced ROS are involved in initiation and promotion of carcinogenesis. Therefore, detoxification of ROS by exogenous antioxidants including dietary polyphenols offers an important strategy for cancer prevention. Recent research results have shown that resistance of cancer stem cells to therapies is linked to low level of ROS. Interestingly, in vitro and in vivo experiments have reported that radiotherapy- and chemotherapy-induced ROS in cytosol sensitize the tumor cells to death, resulting in tumor growth retardation. This review is an attempt to delineate mechanisms of ROS in carcinogenesis and prevention by dietary compounds. Natural polyphenols and dietary antioxidants hold potential to prevent cancer. Interventions in ROS-mediated signal alteration, apoptosis activation, and modulation of epigenetic processes may offer effective cancer prevention strategy. (author)

Increasing evidence suggests that tomato lycopene may be preventive against the formation and the development of lung cancer. Experimental studies demonstrated that lycopene may inhibit the growth of several cultured lung cancer cells and prevent lung tumorigenesis in animal models through various mechanisms, including a modulation of redox status, cell cycle arrest and/or apoptosis induction, a regulation of growth factor signaling, changes in cell growth-related enzymes, an enhancement of gap junction communication and a prevention of smoke-induced inflammation. In addition, lycopene also inhibited cell invasion, angiogenesis, and metastasis. Several lycopene metabolites have been identified, raising the question as to whether the preventive effects of lycopene on cancer risk is, at least in part, due to its metabolites. Despite these promising reports, it is difficult at the moment to directly relate available experimental data to human pathophysiology. More well controlled clinical intervention trials are needed to further clarify the exact role of lycopene in the prevention of lung cancer cell growth. Such studies should take into consideration subject selection, specific markers of analysis, the levels of carotenoids being tested, metabolism and isomerization of lycopene, interaction with other bioactive food components. This article reviews data on the cancer preventive activities of lycopene, possible mechanisms involved, and the relationship between lycopene consumption and human cancer risk.

2009-02-01

Full Text Available Abstract Background Skin cancer is the most prevalent yet most preventable cancer in the US. While protecting oneself from ultraviolet radiation (UVR can largely reduce risk, rates of unprotected sun exposure remain high. Because the desire to be tan often outweighs health concerns among sunbathers, very few interventions have been successful at reducing sunbathing behavior. Sunless tanning (self-tanners and spray tans, a method of achieving the suntanned look without UVR exposure, might be an effective supplement to prevention interventions. Methods and Design This cluster randomized trial will examine whether a beach-based intervention that promotes sunless tanning as a substitute for sunbathing and includes sun damage imaging and sun safety recommendations is superior to a questionnaire only control group in reducing sunbathing frequency. Female beach visitors (N = 250 will be recruited from 2 public beaches in eastern Massachusetts. Beach site will be the unit of randomization. Follow-up assessment will occur at the end of the summer (1-month following intervention and 1 year later. The primary outcome is average sunbathing time per week. The study was designed to provide 90% power for detecting a difference of .70 hours between conditions (standard deviation of 2.0 at 1-year with an intra-cluster correlation coefficient of 0.01 and assuming a 25% rate of loss to follow-up. Secondary outcomes include frequency of sunburns, use of sunless tanning products, and sun protection behavior. Discussion Interventions might be improved by promoting behavioral substitutes for sun exposure, such as sunless tanners, that create a tanned look without exposure to UVR.

Vietnamese American women’s beliefs and perceptions on cervical cancer, cervical cancer screening, and cancer prevention vaccines: A community-based participatory study

Full Text Available Cervical cancer remains commonly diagnosed in Vietnamese American women. Despite efforts to increase cervical cancer screening among Vietnamese American women, participation rates are persistently lower than the national goal. The objective of this study is to explore beliefs of Vietnamese American women about cervical cancer, cervical cancer screening, and cancer prevention vaccines. A qualitative descriptive investigation captured group perceptions about meaning and beliefs of cervical cancer, screening, and cancer prevention vaccines, and participants’ stories using a community-based participatory research approach. Forty Vietnamese American women were recruited from the Portland, Oregon metropolitan area into four focus groups. Using a process of directed content analysis, focus group transcripts were coded for themes. We found that cervical cancer continues to be a difficult topic to discuss, and Vietnamese American women may not bring the topic up themselves to their health care providers. Some women experienced intense emotions of fear or shame of having their cervix examined. Women delayed seeking cervical cancer screening and needed to have early warning signs, which guided them as to when to seek health care. Women focused on cleanliness through vaginal and/or perineal washing as primary prevention for cervical cancer. There were limited awareness and knowledge about cancer prevention vaccines, specifically the human papillomavirus. Some women relied heavily on their informal social networks of family, friends, or community for health knowledge. Fear and misunderstanding dominated the beliefs of Vietnamese American women about cervical cancer screening and prevention. These findings underscored the importance of having culturally-specific findings, which will inform a multicomponent intervention to promote cervical cancer screening and cancer prevention vaccine uptake within this population.

Skin cancer prevention and detection campaigns targeting specific groups are necessary and have proven to be more effective than those aimed at the general population. Interventions in outdoor tourist spots have proven successful, although none have specifically targeted golf courses. The aims of this study were to describe the risk profile of golfers and golf course workers and evaluate the impact of a skin cancer prevention and early detection intervention. This was a cross-sectional descriptive study conducted at 6 golf courses. The intervention included a skin examination and completion of a questionnaire about demographic details, risk factors, and sun exposure and sun protection habits. Participants were also given advice on sun protection measures, self-examination, and use of sunscreens, and were asked about their satisfaction with the intervention and their intention to change their current behaviors. The effect was measured in terms of the diagnoses made, satisfaction with the intervention, reported intention to change, and potential effect in terms of existing risk factors. Of the 351 participants (57% golfers and 43% golf course workers), 70.4% had fair skin, 11.7% had a family history of skin cancer, and 8.5% had a personal history of skin cancer. Skin cancer and actinic keratoses were diagnosed in 10.7% and 40% of the golfers, respectively. The session was rated positively by 99.4% of the participants; 93.9% stated that they intended to improve their sun exposure habits and 93.4% said that they planned to examine their skin more frequently. Our findings confirm that golf course workers and, in particular, golfers are an important target for skin cancer prevention campaigns. This is the first intervention to specifically target golf courses, and it proved to be both feasible and useful. Its success appears to be attributable to numerous factors: it was conducted at golf courses, had multiple components, and was preceded by a motivational campaign

Deaf persons, a documented minority population, have low reading levels and difficulty communicating with physicians. The effect of these on their knowledge of cancer prevention recommendations is unknown. A cross-sectional study of 222 d/Deaf persons in Michigan, age 18 and older, chose one of four ways (voice, video of a certified American Sign Language interpreter, captions, or printed English) to complete a self-administered computer video questionnaire about demographics, hearing loss, language history, health-care utilization, and health-care information sources, as well as family and social variables. Twelve questions tested their knowledge of cancer prevention recommendations. The outcome measures were the percentage of correct answers to the questions and the association of multiple variables with these responses. Participants averaged 22.9% correct answers with no gender difference. Univariate analysis revealed that smoking history, types of medical problems, last physician visit, and women having previous cancer preventive tests did not affect scores. Improved scores occurred with computer use (p = 0.05), higher education (p internet (p = 0.02), and believing that smoking is bad (p bad (p = 0.05) were associated with improved scores. Persons with profound hearing loss have poor knowledge of recommended cancer prevention interventions. English use in multiple settings was strongly associated with increased knowledge.

Infections caused by high-risk human papillomavirus (HPV) are responsible for 7.7% of cancers in developing countries, mainly cervical cancer. This disease is steadily increasing in sub-Saharan Africa, with more than 75,000 new cases and 50,000 deaths yearly, further increased by HIV infection. Areas covered: The current status of cervical cancer associated with HPV in sub-Saharan Africa has been systematically revised. The main issues discussed here are related to the public health burden of cervical cancer in sub-Saharan Africa and predictions for the coming decades, including molecular epidemiology and determinants of HPV infection in Africa, and promising prevention measures currently being evaluated in Africa. Expert commentary: By the year 2030, cervical cancer will kill more than 443,000 women yearly worldwide, most of them in sub-Saharan Africa. The increase in the incidence of cervical cancer in Africa could counteract the progress made by African women in reducing maternal mortality and longevity. Nevertheless, cervical cancer is a potentially preventable noncommunicable disease, and intervention strategies to eliminate cervical cancer as a public health concern should be urgently implemented.

2015-12-23

Oral mucositis is a side effect of chemotherapy, head and neck radiotherapy, and targeted therapy, affecting over 75% of high risk patients. Ulceration can lead to severe pain and difficulty eating and drinking, which may necessitate opioid analgesics, hospitalisation and nasogastric or intravenous nutrition. These complications may lead to interruptions or alterations to cancer therapy, which may reduce survival. There is also a risk of death from sepsis if pathogens enter the ulcers of immunocompromised patients. Ulcerative oral mucositis can be costly to healthcare systems, yet there are few preventive interventions proven to be beneficial. Oral cryotherapy is a low-cost, simple intervention which is unlikely to cause side-effects. It has shown promise in clinical trials and warrants an up-to-date Cochrane review to assess and summarise the international evidence. To assess the effects of oral cryotherapy for preventing oral mucositis in patients with cancer who are receiving treatment. We searched the following databases: the Cochrane Oral Health Group Trials Register (to 17 June 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (Cochrane Library 2015, Issue 5), MEDLINE via Ovid (1946 to 17 June 2015), EMBASE via Ovid (1980 to 17 June 2015), CANCERLIT via PubMed (1950 to 17 June 2015) and CINAHL via EBSCO (1937 to 17 June 2015). We searched the US National Institutes of Health Trials Registry, and the WHO Clinical Trials Registry Platform for ongoing trials. No restrictions were placed on the language or date of publication when searching databases. We included parallel-design randomised controlled trials (RCTs) assessing the effects of oral cryotherapy in patients with cancer receiving treatment. We used outcomes from a published core outcome set registered on the COMET website. Two review authors independently screened the results of electronic searches, extracted data and assessed risk of bias. We contacted study authors for information

To that effect, the National Cancer Registry of The Gambia (NCR, a population-based cancer registry (PBCR, was established in 1986 to actively collect data on all cancer diagnosis nation-wide. We extracted 20-years (1990-2009 of data to assess for the first time, the evolution of the most common cancers, also describe and demonstrate the role of the PBCR in a hepatitis B and liver cancer prevention programme in this population.We estimated Age-Standardised Incidence Rates (ASR (W of the most common cancers registered during the period by gender. The registration period was divided into four 5-year intervals and incidence rates were estimated for each interval. The most common cancers in males were liver, prostate, lung plus bronchus, non-Hodgkin lymphoma (NHL and stomach, accounting for 60%, 5%, 4%, 5% and 3%, respectively. Similarly, cancers of the cervix uteri, liver, breast and NHL, were the most common in females, accounting for 33%, 24%, 11% and 4% of the female cancers, respectively.Cancer incidence has remained relatively stable over time, but as shown elsewhere in sub-Saharan Africa the disease is a threat in The Gambia. The infection related cancers which are mostly preventable (HBV in men and HPV/HIV in women were the most common. At the moment the data is not enough to detect an effect of hepatitis B vaccination on liver cancer incidence in The Gambia. However, we observed that monitoring case occurrence through PBCR is a key public health pre-requisite for rational planning and implementation of targeted interventions for improving the health of the population.

Cancer prevention and early detection strategies are fundamental to reducing breast cancer burden. Offering prevention guidance on modifiable risk factors within early detection settings is rare. We aimed to evaluate the acceptability of a magazine focused on lifestyle and cancer prevention for use in breast screening clinics. A lifestyle magazine was developed and distributed within two breast screening settings in the West of Scotland over a 2-month period. Women were either offered the magazine on arrival or in a self-service format. Uptake was recorded by NHS staff. Women's views were sought via an evaluation questionnaire. Staff were interviewed on their experiences of intervention delivery. Uptake was greatest when offered to attendees (95% vs. 20% self-service). The evaluation questionnaire response rate was 17.3%. Almost 60% of respondents reported an increased knowledge about breast cancer and lifestyle and felt motivated to find out more about cancer prevention and 40% expressed intentions to make lifestyle changes. Over 90% of respondents thought lifestyle factors were important in breast cancer prevention. Staff feedback was positive, indicating no detrimental effects on workloads. In conclusion, a cancer prevention lifestyle magazine can be successfully delivered in the breast screening setting and deserves further exploration for roll out. © 2018 John Wiley & Sons Ltd.

Excessive exposure to the sun during childhood is strongly associated with the development of skin cancer in the future. The only way to prevent the development of skin cancer is to protect against ultraviolet radiation, which can be achieved through strategic awareness during childhood and adolescence. The aim of this work was to evaluate the impact of educational activities for rural and urban students to promote the use of sunscreens and prevent skin cancer. This study was carried out with students (9-12 years) of rural (n=70) and urban (n=70) schools in Rio Grande do Sul state, Brazil. The educational interventions were lectures and games. The impact of this strategy was evaluated through the application of a questionnaire before and after the interventions. Before the intervention, it was found around 50% of rural and urban students were not aware of the damage caused by sun exposure, often exposing themselves to UV radiation without use sunscreen ( ~ 25 %) and at the most critical times of the day/year. After the lectures we observed an improvement in the behavior of the students with regard to sun exposure and knowledge about skin cancer. The results of this study emphasize the importance of prevention strategies for skin cancer and promoting the use of sunscreens based educational strategies. The interventions were of great value in relation to disseminating knowledge on the subject.

Obesity prevention is an international public health priority. The prevalence of obesity and overweight is increasing in child populations throughout the world, impacting on short and long-term health. Obesity prevention strategies for children can change behaviour but efficacy in terms of preventing obesity remains poorly understood. To assess the effectiveness of interventions designed to prevent obesity in childhood through diet, physical activity and/or lifestyle and social support. MEDLINE, PsycINFO, EMBASE, CINAHL and CENTRAL were searched from 1990 to February 2005. Non-English language papers were included and experts contacted. Randomised controlled trials and controlled clinical trials with minimum duration twelve weeks. Two reviewers independently extracted data and assessed study quality. Twenty-two studies were included; ten long-term (at least 12 months) and twelve short-term (12 weeks to 12 months). Nineteen were school/preschool-based interventions, one was a community-based intervention targeting low-income families, and two were family-based interventions targeting non-obese children of obese or overweight parents. Six of the ten long-term studies combined dietary education and physical activity interventions; five resulted in no difference in overweight status between groups and one resulted in improvements for girls receiving the intervention, but not boys. Two studies focused on physical activity alone. Of these, a multi-media approach appeared to be effective in preventing obesity. Two studies focused on nutrition education alone, but neither were effective in preventing obesity. Four of the twelve short-term studies focused on interventions to increase physical activity levels, and two of these studies resulted in minor reductions in overweight status in favour of the intervention. The other eight studies combined advice on diet and physical activity, but none had a significant impact. The studies were heterogeneous in terms of study design

Group interventions have assumed a growing role in primary prevention and supportive care for cancer and HIV disease. Earlier sections of this Special Report examined empirical findings for these interventions and provided recommendations for future research. The current section offers brief recommendations for service providers, policymakers, and stakeholders. Group services now occupy an increasingly prominent place in primary prevention programs and medical settings. In previous sections of this Special Report (Sherman, Leszcz et al., 2004; Sherman, Mosier et al., 2004a, 2004b) we examined the efficacy of different group interventions at different phases of cancer or HIV disease, considered characteristics of the intervention and the participants that might influence outcomes, and discussed mechanisms of action. Methodological challenges and priorities for future research were highlighted. In this, the final section, we offer brief recommendations for service providers, policymakers, and other stakeholders. We consider some of the barriers that constrain use of empirically-based group interventions and note how these programs might be implemented more widely and effectively.

Targeted Therapy for Breast Cancer Prevention

den Hollander, Petra; Savage, Michelle I.; Brown, Powel H.

2013-01-01

With a better understanding of the etiology of breast cancer, molecularly targeted drugs have been developed and are being testing for the treatment and prevention of breast cancer. Targeted drugs that inhibit the estrogen receptor (ER) or estrogen-activated pathways include the selective ER modulators (tamoxifen, raloxifene, and lasofoxifene) and aromatase inhibitors (AIs) (anastrozole, letrozole, and exemestane) have been tested in preclinical and clinical studies. Tamoxifen and raloxifene have been shown to reduce the risk of breast cancer and promising results of AIs in breast cancer trials, suggest that AIs might be even more effective in the prevention of ER-positive breast cancer. However, these agents only prevent ER-positive breast cancer. Therefore, current research is focused on identifying preventive therapies for other forms of breast cancer such as human epidermal growth factor receptor 2 (HER2)-positive and triple-negative breast cancer (TNBC, breast cancer that does express ER, progesterone receptor, or HER2). HER2-positive breast cancers are currently treated with anti-HER2 therapies including trastuzumab and lapatinib, and preclinical and clinical studies are now being conducted to test these drugs for the prevention of HER2-positive breast cancers. Several promising agents currently being tested in cancer prevention trials for the prevention of TNBC include poly(ADP-ribose) polymerase inhibitors, vitamin D, and rexinoids, both of which activate nuclear hormone receptors (the vitamin D and retinoid X receptors). This review discusses currently used breast cancer preventive drugs, and describes the progress of research striving to identify and develop more effective preventive agents for all forms of breast cancer.

We determined the effectiveness of a community-based breast cancer education intervention among understudied populations in the New York State (NYS) Capital Region by assessing and comparing baseline and post-education breast cancer knowledge. Participants included 417 students recruited from five colleges/universities and 67 women from four community group organizations. Baseline and post-education knowledge was assessed via self-administered mostly multiple-choice questionnaires. An open-ended question soliciting opinions about public health prevention strategies against breast cancer was included on college/university students' questionnaires. Effectiveness of education intervention was estimated through a paired t test. Stratified analysis was done using demographic and descriptive variables. Answers to the open-ended questions were analyzed qualitatively. The mean percentage of correct answers increased from 39.9% at baseline to 80.8% post-education (P raising awareness about modifiable risk factors and inspiring proactive thinking about public health prevention strategies. This community-based education intervention was effective in increasing breast cancer knowledge among demographically diverse groups with low levels of baseline knowledge in the NYS Capital Region. Our findings provide leads for future public health prevention strategies.

Persistent new HIV infections and risky behaviors underscore the need for enhanced HIV prevention. Social media interventions may promote safe sexual behaviors, increase HIV testing uptake, and promote safe injection behaviors. This review discusses how social media interventions tap into the wisdom of crowds through crowdsourcing, build peer-mentored communities, and deliver interventions through social networks. Social media HIV prevention interventions are constrained by ethical issues, low social media usage among some key populations, and implementation issues. Comprehensive measurement of social media interventions to prevent HIV is necessary, but requires further development of metrics.

Prevention programs have not achieved the expected results in preventing mortality from breast and cervical cancer in Mexico. Therefore, we propose a complementary strategy. An educational strategy for high school students in Mexico (2011-2013) was designed (longitudinal design, two measurements and a single intervention). The postintervention assessment included: 1) knowledge acquired by students about cancer prevention and 2) The performance of the student as a health promoter in their household. The strategy was based on analysis of cases and developed in three sessions. An assessment tool was designed and validated (Test-Retest). The levels of knowledge according to the qualifications expected by chance were determined. Wilcoxon test compared results before and after intervention. An assessment instrument with 0.80 reliability was obtained. 831 high school students were analyzed. Wilcoxon rank-sum test showed a significant learning after the intervention (Z = - 2.64, p = 0.008) with improvement of levels of knowledge in a 154.5%. 49% of students had a good performance as health promoters. The learning in preventive measures is important to sensitize individuals to prevention campaigns against cancer. This strategy proved to improve the level of knowledge of students in an easy and affordable way.

We have entered a transformative period in cancer prevention (including early detection). Remarkable progress in precision medicine and immune-oncology, driven by extraordinary recent advances in genome-wide sequencing, big-data analytics, blood-based technologies, and deep understanding of the tumor immune microenvironment (TME), has provided unprecedented possibilities to study the biology of premalignancy. The pace of research and discovery in precision medicine and immunoprevention has been astonishing and includes the following clinical firsts reported in 2015: driver mutations detected in circulating cell-free DNA in patients with premalignant lesions (lung); clonal hematopoiesis shown to be a premalignant state; molecular selection in chemoprevention randomized controlled trial (RCT; oral); striking efficacy in RCT of combination chemoprevention targeting signaling pathway alterations mechanistically linked to germline mutation (duodenum); molecular markers for early detection validated for lung cancer and showing promise for pancreatic, liver, and ovarian cancer. Identification of HPV as the essential cause of a major global cancer burden, including HPV16 as the single driver of an epidemic of oropharyngeal cancer in men, provides unique opportunities for the dissemination and implementation of public health interventions. Important to immunoprevention beyond viral vaccines, genetic drivers of premalignant progression were associated with increasing immunosuppressive TME; and Kras vaccine efficacy in pancreas genetically engineered mouse (GEM) model required an inhibitory adjuvant (Treg depletion). In addition to developing new (e.g., epigenetic) TME regulators, recent mechanistic studies of repurposed drugs (aspirin, metformin, and tamoxifen) have identified potent immune activity. Just as precision medicine and immune-oncology are revolutionizing cancer therapy, these approaches are transforming cancer prevention. Here, we set out a brief agenda for the

The death rate from colorectal cancer is high and affects poor and medically underserved populations disproportionately. In the United States, health disparities are particularly acute in the Lower Mississippi River Delta region. Because many in the region have limited access to basic health care resources, they are not screened for cancer, even though screening is one of the most effective strategies to prevent colorectal cancer. Community-based participatory research is a promising approach to prevent colorectal cancer in this population. The Empowering Communities for Life program was implemented in 2 underserved counties in the Arkansas Lower Mississippi River Delta. The program arose from a 9-year partnership between the University of Arkansas for Medical Sciences and 9 cancer councils across Arkansas. Empowering Communities for Life is a community-based participatory intervention designed to increase colorectal cancer screening in rural, underserved communities through fecal occult blood testing. Community and academic partners collaborated to develop research infrastructure, intervention materials and methods, and the assessment instrument. Project outcomes were strengthened community-academic partnerships, certification of community partners in conducting human subjects research, development of a randomized controlled design to test the intervention's efficacy, an interactive PowerPoint presentation, an informational pamphlet, the certification of 6 lay health advisors and 22 role models to provide the intervention, and an assessment tool using an audience response system. Lessons learned in working collaboratively with diverse groups include the importance of meeting face to face and listening.

As a commensal or a pathogen, Helicobacter pylori can change the balance of a complex interaction that exists among gastric epithelial cells, microbes, and their environment. Therefore, unraveling this complex relationship of these mixtures can be expected to help prevent cancer as well as troublesome unmet medical needs of H. pylori infection. Though gastric carcinogenesis is a multi-step process, precancerous lesion can be reversible in the early phase of mucosal damage before reaching the stage of no return. However, biomarkers to predict rejuvenation of precancerous atrophic gastritis have not been identified yet and gastric cancer prevention is still regarded as an impregnable fortress. However, when we take the journey from H. pylori-associated gastritis to gastric cancer, it provides us with the clue for prevention since there are two main preventive strategies: eradication and anti-inflammation. The evidence supporting the former strategy is now ongoing in Japan through a nation-wide effort to eradicate H. pylori in patients with chronic gastritis, but suboptimal apprehension to increasing H. pylori resistance to antibiotics and patient non-compliance still exists. The latter strategy has been continued in the author'sresearch center under siTRP (short-term intervention to revert premalignant lesion) strategy. By focusing on the role of inflammation in the development of H. pylori-associated gastric carcinogenesis, this review is intended to explain the connection between inflammation and gastric cancer. Strategies on H. pylori eradication, removal of inflammation, and reverting preneoplastic lesion will also be introduced. In the end, we expect to be able to prevent gastric cancer by take a detour from the unpleasant journey, i.e. from H. pylori-associated gastritis to gastric cancer.

In the second study, women's breast cancer preventive behaviours increased significantly one month post intervention in the educational group (MD 1.21, SD 2.54; 65 women; low-quality evidence) compared to the control group (MD 0.15, SD 2.94; 65 women; P Cancer AwarenessWomen's overall breast cancer awareness did not change in intervention group 1 compared to control at two years postintervention (OR 1.8, 95% CI 0.6 to 5.30; P = 0.32; 435 women; moderate-quality evidence) while overall awareness increased in the intervention group 2 compared to control at two years postintervention (OR 8.1, 95% CI 2.7 to 25.0; P awareness and perceived susceptibility) at one month postintervention in the educational group (mean 1.21, SD 2.54; 65 women) compared to the control group (mean 0.15, SD 2.94; 65 women; P = 0.045).Neither study reported outcomes relating to motivation to check their breasts, confidence to seek help, time from breast symptom discovery to presentation to a healthcare professional, intentions to seek help, quality of life, adverse effects of the interventions, stages of breast cancer, survival estimates or breast cancer mortality rates. Based on the results of two RCTs, a brief intervention has the potential to increase women's breast cancer awareness. However, findings of this review should be interpreted with caution, as GRADE assessment identified moderate-quality evidence in only one of the two studies reviewed. In addition, the included trials were heterogeneous in terms of the interventions, population studied and outcomes measured. Therefore, current evidence cannot be generalised to the wider context. Further studies including larger samples, validated outcome measures and longitudinal approaches are warranted.

Nutritional interventions for survivors of childhood cancer.

Childhood cancer survivors are at a higher risk of developing health conditions such as osteoporosis, and cardiovascular disease than their peers. Health-promoting behaviour, such as consuming a healthy diet, could lessen the impact of these chronic issues, yet the prevalence rate of health-protecting behaviour amongst survivors of childhood cancer is similar to that of the general population. Targeted nutritional interventions may prevent or reduce the incidence of these chronic diseases. The primary aim of this review was to assess the efficacy of a range of nutritional interventions designed to improve the nutritional intake of childhood cancer survivors, as compared to a control group of childhood cancer survivors who did not receive the intervention. Secondary objectives were to assess metabolic and cardiovascular risk factors, measures of weight and body fat distribution, behavioural change, changes in knowledge regarding disease risk and nutritional intake, participants' views of the intervention, measures of health status and quality of life, measures of harm associated with the process or outcomes of the intervention, and cost-effectiveness of the intervention We searched the electronic databases of the Cochrane Central Register of Controlled Trials (CENTRAL; 2013, Issue 3), MEDLINE/PubMed (from 1945 to April 2013), and Embase/Ovid (from 1980 to April 2013). We ran the search again in August 2015; we have not yet fully assessed these results, but we have identified one ongoing trial. We conducted additional searching of ongoing trial registers - the International Standard Randomised Controlled Trial Number register and the National Institutes of Health register (both screened in the first half of 2013) - reference lists of relevant articles and reviews, and conference proceedings of the International Society for Paediatric Oncology and the International Conference on Long-Term Complications of Treatment of Children and Adolescents for Cancer (both 2008 to

Towards prevention of ovarian cancer.

2018-01-01

Ovarian cancer is the leading cause of death of all gynaecological cancers. To date, there is no reliable, specific screening procedure for detecting ovarian cancer. The risk factors of ovarian cancer include modifiable and non-modifiable factors. The main goal of the ovarian cancer prevention program is to significantly reduce the risk of development of ovarian cancer and other cancers such as breast and/or peritoneal cancer. The application of non-surgical preventive approaches such as oral contraceptives, parity and breastfeeding has been shown to be highly protective against ovarian cancer development. Targeting inflammation has been also reported to be associated with a protective trend against ovarian cancer and can be achieved through either non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin or lifestyle modifications or both. Lifestyle modification that includes regular exercise, healthy diet supplemented with anti-oxidants and anti-inflammatory elements reduces the risk of the disease even further. Surgical protective approaches include; tubal ligation, hysterectomy and prophylactic bilateral salpingo-oophorectomy and the former is the most effective approach to protect against ovarian cancer. A better understanding of the risk factors of ovarian cancer and the current approaches to prevent it may increase the awareness and help to decrease the incidence of ovarian cancer, increase the five-year survival rate and decrease the mortality rate significantly in the general population especially among those at high risk for ovarian cancer. This review is an attempt to outline a potential program of ovarian cancer prevention and the potential challenges.

2012-02-01

Endocrine therapy with selective estrogen receptor modulators (SERMs) has been the mainstay of breast cancer prevention trials to date. The aromatase inhibitors, which inhibit the final chemical conversion of androgens to estrogens, have shown increased disease-free survival benefit over tamoxifen in patients with primary hormone receptor-positive breast cancer, as well as reducing the risk of developing contralateral breast cancers. The aromatase inhibitors are being actively evaluated as prevention agents for women with a history of ductal carcinoma in situ as well as for women who are considered to be at high risk for developing primary invasive breast cancer. This review evaluates the available prevention data, as evidenced by the decrease in contralateral breast cancers, when aromatase inhibitors are used in the adjuvant setting, as well as the emerging data of the aromatase inhibitors specifically tested in the prevention setting for women at high risk. Exemestane is a viable option for breast cancer prevention. We continue to await further follow-up on exemestane as well as other aromatase inhibitors in the prevention setting for women at high risk of developing breast cancer or with a history of ductal carcinoma in situ.

[Economic and political aspects of prostate cancer prevention].

Science.gov (United States)

Durand-Zaleski, I

2008-04-01

Deciding on a health policy in practice means dedicating human and financial resources and prioritising spendings. The economic evaluation of prevention strategies attempts to establish a relationship between the medical benefit of prevention and its additional cost (or in some cases cost reduction) compared to no prevention. Decisions on reimbursing drugs, interventions or funding health programmes do not usually follow efficiency criteria which define economic rationality. Politics may for example decide to make prostate cancer a public health priority if mortality in a country or in some regions of the country appears to be excessively high. Economic rationality alone is not an appropriate factor on which to base a decision which may be purely political, reflecting the actual values of the society at a given point in time.

Review article: Medical decision models of Helicobacter pylori therapy to prevent gastric cancer.

Science.gov (United States)

Sonnenberg, A; Inadomi, J M

1998-02-01

The aim of the present article is to study the utility of Helicobacter pylori eradication programmes in decreasing the incidence of gastric cancer. Three types of decision models are employed to pursue this aim, i.e. decision tree, present value, and declining exponential approximation of life expectancy (DEALE). 1) A decision tree allows one to model the interaction of multiple variables in great detail and to calculate the marginal cost, as well as the marginal cost-benefit ratio, of a preventive strategy. The cost of gastric cancer, the efficacy of H. pylori therapy in preventing cancer, and the cumulative probability of developing gastric cancer exert the largest influence on the marginal cost of cancer prevention. The high cost of future gastric cancer and a high efficacy of therapy make screening for H. pylori and its eradication the preferred strategy. 2) The present value is an economic method to adjust future costs or benefits to their current value using a discount rate and the length of time between now and a given time point in the future. It accounts for the depreciation of money and all material values over time. During childhood, the present value of future gastric cancer is very low. Vaccination of children to prevent gastric cancer would need to be very inexpensive to be practicable. Cancer prevention becomes a feasible option, only if the time period between the preventive measures and the occurrence of gastric cancer can be made relatively short. 3) The DEALE provides a means to calculate the increase in life expectancy that would occur, if death from a particular disease became preventable. Life expectancy of the general population is hardly affected by gastric cancer. For life expectancy to increase appreciably by vaccination or antibiotic therapy directed against H. pylori infection, these interventions would need to be focused towards a sub-population with an a priori high risk for gastric cancer.

Identifying molecular targets of lifestyle modifications in colon cancer prevention

Full Text Available One in four deaths in the United States is cancer-related, and colorectal cancer (CRC is the second leading cause of cancer-associated deaths. Screening strategies are utilized but have not reduced disease incidence or mortality. In this regard, there is an interest in cancer preventive strategies focusing on lifestyle intervention, where specific etiologic factors involved in cancer initiation, promotion, and progression could be targeted. For example, exposure to dietary carcinogens, such as nitrosamines and polycyclic aromatic hydrocarbons influences colon carcinogenesis. Furthermore, dietary deficiencies could alter sensitivity to genetic damage and influence carcinogen metabolism contributing to CRC. High alcohol consumption increases the risk of mutations including the fact that acetaldehyde, an ethanol metabolite, is classified as a group 1 carcinogen. Tobacco smoke exposure is also a risk factor for cancer development; ~20% of CRCs are associated with smoking. Additionally, obese patients have a higher risk of cancer development, which is further supported by the fact that physical activity decreases CRC risk by 55%. Similarly, chronic inflammatory conditions also increase the risk of CRC development. Moreover, the circadian clock alters digestion and regulates other biochemical, physiological and behavioral processes that could positively influence CRC. Taken together, colon carcinogenesis involves a number of etiological factors, and therefore, to create effective preventive strategies, molecular targets need to be identified and beleaguered prior to disease progression. With this in mind, the following is a comprehensive review identifying downstream target proteins of the above lifestyle risk factors, which are modulated during colon carcinogenesis and could be targeted for CRC prevention by novel agents including phytochemicals.

Modeling Cervical Cancer Prevention in Developed Countries

2009-01-01

Cytology-based screening has reduced cervical cancer mortality in countries able to implement, sustain and financially support organized programs that achieve broad coverage. These ongoing secondary prevention efforts considerably complicate the question of whether vaccination against Human Papillomavirus (HPV) types -16 and 18 should be introduced. Policy questions focus primarily on the target ages of vaccination, appropriate ages for a temporary “catch-up” program, possible revisions in screening policies to optimize synergies with vaccination, including the increased used of HPV DNA testing, and the inclusion of boys in the vaccination program. Decision-analytic models are increasingly being developed to simulate disease burden and interventions in different settings in order to evaluate the benefits and cost-effectiveness of primary and secondary interventions for informed decision-making. This article is a focused review on existing mathematical models that have been used to evaluate HPV vaccination in the context of developed countries with existing screening programs. Despite variations in model assumptions and uncertainty in existing data, pre-adolescent vaccination of girls is consistently found to be attractive in the context of current screening practices, provided there is complete and lifelong vaccine protection and widespread vaccination coverage. Questions related to catch-up vaccination programs, potential benefits of other non-cervical cancer outcomes and inclusion of boys are subject to far more uncertainty, and results from these analyses have reached conflicting conclusions. Most analyses find that some catch-up vaccination is warranted but becomes increasingly unattractive as the catch-up age is extended, and vaccination of boys is unlikely to be cost-effective if reasonable levels of coverage are achieved in girls or coverage among girls can be improved. The objective of the review is to highlight points of consensus and qualitative

Full Text Available Introduction: Preventive behaviors such as screening tests have an important role in prevention and control of breast cancer. Therefore, this study aimed to determine the effect of educational programs on preventive behaviors of breast cancer based on the health belief model among female teachers of guidance schools in Zahedan city. Materials and Methods: This quasi-experimental study was performed on 240 female teachers from (120 participants in each of the control and intervention groups Zahedan guidance schools. The data-gathering tool was a multipart questionnaire containing demographic variables, knowledge and health belief model structures. An educational program was performed based on the health belief model in five sessions through lectures, training videos, question and answer session for participants in the intervention group. Questionnaires were filled before and two months after the intervention in the two groups. Data was analyzed by independent T-test, chi-square and multiple linear regressions using SPSS-15 software. Results: There was no meaningful difference in the mean scores of knowledge, health belief model constructs, and performance between the two groups before the educational intervention, but the mean scores of variables increased significantly after the intervention (P< 0.05. Conclusion: The health belief model was effective to promote preventive behaviors. Hence, educational interventions with an emphasis on raising awareness, change in beliefs and improving self-efficacy regarding breast cancer are recommended

The missing piece: cancer prevention within psycho-oncology - a commentary.

Rosberger, Zeev; Perez, Samara; Bloom, Joan; Shapiro, Gilla K; Fielding, Richard

2015-09-10

In this commentary, we review the place of prevention within the field of Psycho-Oncology. The thrust of Psycho-Oncology's clinical and research efforts have historically focused on behavioral and social factors implicated in the cancer patients' experience from detection and diagnosis, to treatment, survivorship and end of life along the cancer trajectory. This conceptualization has raised the standards for research, leading to a better understanding of the patient experience and the delivery of highly effective interventions to improve quality of life. Emerging data on the role of potential prevention behaviors (e.g., diet and exercise, smoking cessation, screening, etc.) suggests that Psycho-Oncology has a significant role to play in understanding and intervening on a population level to reduce cancer incidence. We present and describe an expanded model of research in Psycho-Oncology which incorporates psychosocial variables in prevention research to complement Holland et al.'s (1998, 2010) original model. The implications of this model are discussed in relation to research, clinical work and training within the discipline of Psycho-Oncology. Copyright © 2015 John Wiley & Sons, Ltd.

To assess the role of Intervention Mapping (IM) in designing disease prevention interventions worldwide. Systematic search and review of the relevant literature-peer-reviewed and grey-was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. Only five of the twenty two included studies reviewed were RCTs that compared intervention using IM protocol with placebo intervention, and provided the outcomes in terms of percentage increase in the uptake of disease-prevention programmes, and only one of the five studies provided an effect measure in the form of relative risk (RR = 1.59, 95% CI = 1.08-2.34, p = 0.02). Of the five RCTs, three were rated as strong evidences, one as a medium evidence and one as a weak evidence, and they all reported statistically significant difference between the two study groups, with disease prevention interventions that have used the intervention mapping approach generally reported significant increases in the uptake of disease-prevention interventions, ranging from 9% to 28.5% (0.0001 ≤ p ≤ 0.02), On the other hand, all the 22 studies have successfully identified the determinants of the uptake of disease prevention interventions that is essential to the success of disease prevention programmes. Intervention Mapping has been successfully used to plan, implement and evaluate interventions that showed significant increase in uptake of disease prevention programmes. This study has provided a good understanding of the role of intervention mapping in designing disease prevention interventions, and a good foundation upon which subsequent reviews can be guided.

Diet and Pancreatic Cancer Prevention

Directory of Open Access Journals (Sweden)

Ilaria Casari

Full Text Available Pancreatic cancer is without any doubt the malignancy with the poorest prognosis and the lowest survival rate. This highly aggressive disease is rarely diagnosed at an early stage and difficult to treat due to its resistance to radiotherapy and chemotherapy. Therefore, there is an urgent need to clarify the causes responsible for pancreatic cancer and to identify preventive strategies to reduce its incidence in the population. Some circumstances, such as smoking habits, being overweight and diabetes, have been identified as potentially predisposing factors to pancreatic cancer, suggesting that diet might play a role. A diet low in fat and sugars, together with a healthy lifestyle, regular exercise, weight reduction and not smoking, may contribute to prevent pancreatic cancer and many other cancer types. In addition, increasing evidence suggests that some food may have chemo preventive properties. Indeed, a high dietary intake of fresh fruit and vegetables has been shown to reduce the risk of developing pancreatic cancer, and recent epidemiological studies have associated nut consumption with a protective effect against it. Therefore, diet could have an impact on the development of pancreatic cancer and further investigations are needed to assess the potential chemo preventive role of specific foods against this disease. This review summarizes the key evidence for the role of dietary habits and their effect on pancreatic cancer and focuses on possible mechanisms for the association between diet and risk of pancreatic cancer.

Oncologists have a critical opportunity to utilize risk assessment and cancer prevention strategies to interrupt the initiation or progression of cancer in cancer survivors and individuals at high risk of developing cancer. Expanding knowledge about the natural history and prognosis of cancers positions oncologists to advise patients regarding the risk of second malignancies and treatment-related cancers. In addition, as recognized experts in the full spectrum of cancer care, oncologists are afforded opportunities for involvement in community-based cancer prevention activities. Although oncologists are currently providing many cancer prevention and risk assessment services to their patients, economic barriers exist, including inadequate or lack of insurance, that may compromise uniform patient access to these services. Additionally, insufficient reimbursement for existing and developing interventions may discourage patient access to these services. The American Society of Clinical Oncology (ASCO), the medical society representing cancer specialists involved in patient care and clinical research, is committed to supporting oncologists in their wide-ranging involvement in cancer prevention. This statement on risk assessment and prevention counseling, although not intended to be a comprehensive overview of cancer prevention describes the current role of oncologists in risk assessment and prevention; provides examples of risk assessment and prevention activities that should be offered by oncologists; identifies potential opportunities for coordination between oncologists and primary care physicians in prevention education and coordination of care for cancer survivors; describes ASCO's involvement in education and training of oncologists regarding prevention; and proposes improvement in the payment environment to encourage patient access to these services.

"War on cancer" was declared through the National Cancer Act by President Richard Nixon in 1971, but cancer statistics from the American Cancer Society and other sources indicated the failure of this war, suggesting instead focus on the message that a "prevention strategy" might be much more effective than cancer treatment. While cancer statistics notoriously showed sharp increases in incidence as well as in mortality concurrent with economic growth in Asia, fortunately Asian countries benefit from plentiful resources of natural compounds, which can prevent cancer. Just like cancer chemotherapeutics targeted to kill cancer cells in Western countries, natural agents activating molecular mechanisms for cancer prevention, reversion of premalignant tumors, and even ablation of cancer stem cells, are very abundant in Asia. Currently, these natural agents are under very active investigations targeting the hallmarks of cancer prevention, including selective induction of apoptosis in cancer cells, suppression of growth factors or their signaling, suppression of cell proliferation and of cancer-promoting angiogenesis, induction of mesenchymal-epithelial transition, and disruption of the tumor microenvironment, developing promising cancer preventive agents. However, Asia is the most populous continent in the world and some Asian countries do not have the resources to implement cancer screening programs for early detection or treatment. In addition, despite the excellent cancer preventive screening strategies in some Asian countries, well-designed clinical trials for cancer prevention are somewhat delayed compared to Western countries. In this review article, several phytochemicals/phytoceuticals produced and studied in different Asian countries will be introduced, including Korean red ginseng (pride of Korea), curcumin (Indian spice for life), black or green tea (popular in Japan/Sri Lanka), genistein from tofu (famous Chinese food), diallylsulfide or S-allylcysteine (garlic

OVERVIEW Given the number of lives affected by cancer and the great potential for optimizing well-being via lifestyle changes, patients, providers, health care systems, advocacy groups, and entrepreneurs are looking to digital solutions to enhance patient care and broaden prevention efforts. Thousands of health-oriented mobile websites and apps have been developed, with a majority focused upon lifestyle behaviors (e.g., exercise, diet, smoking). In this review, we consider the use and potential of social media and mHealth technologies for cancer prevention, cancer treatment, and survivorship. We identify key principles in research and practice, summarize prior reviews, and highlight notable case studies and patient resources. Further, with the potential for scaled delivery and broad reach, we consider application of social media and mHealth technologies in low-resource settings. With clear advantages for reach, social media and mHealth technologies offer the ability to scale and engage entire populations at low cost, develop supportive social networks, connect patients and providers, encourage adherence with cancer care, and collect vast quantities of data for advancing cancer research. Development efforts have been rapid and numerous, yet evaluation of intervention effects on behavior change and health outcomes are sorely needed, and regulation around data security issues is notably lacking. Attention to broader audiences is also needed, with targeted development for culturally diverse groups and non-English speakers. Further investment in research to build the evidence base and identify best practices will help delineate and actualize the potential of social media and mHealth technologies for cancer prevention and treatment.

The environment is an underutilized pathway to breast cancer prevention. Current research approaches and funding streams related to breast cancer and the environment are unequal to the task at hand. We undertook the California Breast Cancer Prevention Initiatives, a four-year comprehensive effort to set a research agenda related to breast cancer, the environment, disparities and prevention. We identified 20 topics for Concept Proposals reflecting a life-course approach and the complex etiology of breast cancer; considering the environment as chemical, physical and socially constructed exposures that are experienced concurrently: at home, in the community and at work; and addressing how we should be modifying the world around us to promote a less carcinogenic environment. Redirecting breast cancer research toward prevention-oriented discovery could significantly reduce the incidence and associated disparities of the disease among future generations.

The concept of intraepithelial neoplasm (IEN) as a near-obligate precursor of cancers has generated opportunities to examine drug or device intervention strategies that may reverse or retard the sometimes lengthy process of carcinogenesis. Chemopreventive agents with high therapeutic indices, well-monitored for efficacy and safety, are greatly needed, as is development of less invasive or minimally disruptive visualization and assessment methods to safely screen nominally healthy but at-risk patients, often for extended periods of time and at repeated intervals. Imaging devices, alone or in combination with anticancer drugs, may also provide novel interventions to treat or prevent precancer.

Breast cancer is an increasing public health problem. Substantial advances have been made in the treatment of breast cancer, but the introduction of methods to predict women at elevated risk and prevent the disease has been less successful. Here, we summarize recent data on newer approaches to risk prediction, available approaches to prevention, how new approaches may be made, and the difficult problem of using what we already know to prevent breast cancer in populations. During 2012, the Breast Cancer Campaign facilitated a series of workshops, each covering a specialty area of breast cancer to identify gaps in our knowledge. The risk-and-prevention panel involved in this exercise was asked to expand and update its report and review recent relevant peer-reviewed literature. The enlarged position paper presented here highlights the key gaps in risk-and-prevention research that were identified, together with recommendations for action. The panel estimated from the relevant literature that potentially 50% of breast cancer could be prevented in the subgroup of women at high and moderate risk of breast cancer by using current chemoprevention (tamoxifen, raloxifene, exemestane, and anastrozole) and that, in all women, lifestyle measures, including weight control, exercise, and moderating alcohol intake, could reduce breast cancer risk by about 30%. Risk may be estimated by standard models potentially with the addition of, for example, mammographic density and appropriate single-nucleotide polymorphisms. This review expands on four areas: (a) the prediction of breast cancer risk, (b) the evidence for the effectiveness of preventive therapy and lifestyle approaches to prevention, (c) how understanding the biology of the breast may lead to new targets for prevention, and (d) a summary of published guidelines for preventive approaches and measures required for their implementation. We hope that efforts to fill these and other gaps will lead to considerable advances in our

Global cancer patterns: causes and prevention.

Science.gov (United States)

Vineis, Paolo; Wild, Christopher P

2014-02-08

Cancer is a global and growing, but not uniform, problem. An increasing proportion of the burden is falling on low-income and middle-income countries because of not only demographic change but also a transition in risk factors, whereby the consequences of the globalisation of economies and behaviours are adding to an existing burden of cancers of infectious origin. We argue that primary prevention is a particularly effective way to fight cancer, with between a third and a half of cancers being preventable on the basis of present knowledge of risk factors. Primary prevention has several advantages: the effectiveness could have benefits for people other than those directly targeted, avoidance of exposure to carcinogenic agents is likely to prevent other non-communicable diseases, and the cause could be removed or reduced in the long term--eg, through regulatory measures against occupational or environmental exposures (ie, the preventive effort does not need to be renewed with every generation, which is especially important when resources are in short supply). Primary prevention must therefore be prioritised as an integral part of global cancer control. Copyright © 2014 Elsevier Ltd. All rights reserved.

Selenium for preventing cancer

Full Text Available BACKGROUND: Selenium is a trace element essential to humans. Higher selenium exposure and selenium supplements have been suggested to protect against several types of cancers. OBJECTIVE: Two research questions were addressed in this review: What is the evidence for: 1. an aetiological relationship between selenium exposure and cancer risk in women and men?; 2. the efficacy of selenium supplementation for cancer prevention in women and men? SEARCH STRATEGY: We searched electronic databases and bibliographies of reviews and included publications. SELECTION CRITERIA: We included prospective observational studies to answer research question (a and randomised controlled trials (RCTs to answer research question (b. DATA COLLECTION AND ANALYSIS: We conducted random effects meta-analyses of epidemiological data when five or more studies were retrieved for a specific outcome. We made a narrative summary of data from RCTs. MAIN RESULTS: We included 49 prospective observational studies and six RCTs. In epidemiologic data, we found a reduced cancer incidence (summary odds ratio, OR, 0.69; 95% confidence interval, CI, 0.53 to 0.91 and mortality (OR 0.55, 95% CI 0.36 to 0.83 with higher selenium exposure. Cancer risk was more pronouncedly reduced in men (incidence: OR 0.66, 95% CI 0.42 to 1.05 than in women (incidence: OR 0.90, 95% CI 0.45 to 1.77. These findings have potential limitations due to study design, quality and heterogeneity of the data, which complicated the interpretation of the summary statistics. The RCTs found no protective efficacy of selenium yeast supplementation against non-melanoma skin cancer or L-selenomethionine supplementation against prostate cancer. Study results for the prevention of liver cancer with selenium supplements were inconsistent and studies had an unclear risk of bias. The results of the Nutritional Prevention of Cancer Trial (NPCT and SELECT raised concerns about possible harmful effects of selenium supplements. AUTHORS

Skin cancer is the most common cancer, and it often is preventable. The authors sought to evaluate behavior and knowledge regarding skin cancer among students at a Texas university. The authors recruited a diverse group of students in terms of sex, age, and ethnicity to participate in a survey regarding knowledge of skin cancer signs, use of tanning beds, and performance of self-assessment for skin cancer. Participating students could complete surveys in classrooms, at health fairs, or online via Survey Monkey. The authors examined data for the 3 variables in relation to sex, ethnicity, and age. A total of 512 responses were completed. Female students completed 371 (72.46%) surveys, and male students completed 141 (27.54%). The ethnicity of student participants was nearly evenly split among whites, African Americans, and Hispanics. Ethnicity was the most significant factor influencing the knowledge of skin cancer and behaviors to prevent it. Specifically, Hispanic and African American students possessed a lower level of skin cancer awareness. More female students than male students used tanning beds, and although use was self-reported as infrequent, the results imply that 4500 of the university's students might use tanning beds, which is concerning if extrapolated to other university student populations in Texas. Behavioral intervention is critical in reducing students' risk of skin cancer in later years, and university students must acquire knowledge to increase their awareness of skin health and to minimize their risk of developing skin cancer. Radiation therapists are uniquely positioned to share knowledge of skin cancer. ©2017 American Society of Radiologic Technologists.

Cancer is a major chronic disease threatening the people's health in China. We reviewed the latest advances on cancer surveillance, prevention and control in our country, which may provide important clues for future cancer control. We used data from the National Central Cancer Registry, to describe and analyze the latest cancer statistics in China. We summarized updated informations on cancer control policies, conducting network, as well as programs in the country. We provided important suggestions on the future strategies of cancer prevention and control. The overall cancer burden in China has been increasing during the past decades. In 2014, there were about 3 804 000 new cancer cases and 2 296 000 cancer deaths in China. The age-standardized cancer incidence and mortality rates were 190.63/100 000 and 106.98/100 000, respectively. China has formed a comprehensive network on cancer prevention and control. Nationwide population-based cancer surveillance has been built up. The population coverage of cancer surveillance has been expanded, and the data quality has been improved. As the aging population is increasing and unhealthy life styles persist in our country, there will be an unnegligible cancer burden in China. Based on the comprehensive rationale of cancer control and prevention, National Cancer Center of China will perform its duty for future precise cancer control and prevention, based on cancer surveillance statistics.

The heterogeneity and complexity of advanced cancers strongly supports the rationale for an enhanced focus on molecular prevention as a priority strategy to reduce the burden of cancer. Molecular prevention encompasses traditional chemopreventive agents as well as vaccinations and therapeutic approaches to cancer-predisposing conditions. Despite challenges to the field, we now have refined insights into cancer etiology and early pathogenesis; successful risk assessment and new risk models; agents with broad preventive efficacy (e.g., aspirin) in common chronic diseases, including cancer; and a successful track record of more than 10 agents approved by the FDA for the treatment of precancerous lesions or cancer risk reduction. The development of molecular preventive agents does not differ significantly from the development of therapies for advanced cancers, yet has unique challenges and special considerations given that it most often involves healthy or asymptomatic individuals. Agents, biomarkers, cohorts, overall design, and endpoints are key determinants of molecular preventive trials, as with therapeutic trials, although distinctions exist for each within the preventive setting. Progress in the development and evolution of molecular preventive agents has been steadier in some organ systems, such as breast and skin, than in others. In order for molecular prevention to be fully realized as an effective strategy, a number of challenges to the field must be addressed. Here we provide a brief overview of the context for and special considerations of molecular prevention along with a discussion of the results of major randomized controlled trials. PMID:26284997

Knowing family history is important for understanding cancer risk, yet communication within families is suboptimal. Providing strategies to enhance communication may be useful. Four hundred ninety women were recruited from urban, safety-net, hospital-based primary care women's health clinics. Participants were randomized to receive the KinFact intervention or the control handout on lowering risks for breast/colon cancer and screening recommendations. Cancer family history was reviewed with all participants. The 20-minute KinFact intervention, based in communication and behavior theory, included reviewing individualized breast/colon cancer risks and an interactive presentation about cancer and communication. Study outcomes included whether participants reported collecting family history, shared cancer risk information with relatives, and the frequency of communication with relatives. Data were collected at baseline, 1, 6, and 14 months. Overall, intervention participants were significantly more likely to gather family cancer information at follow-up (odds ratio [OR]: 2.73; 95% confidence interval [CI]: 2.01, 3.71) and to share familial cancer information with relatives (OR: 1.85; 95% CI: 1.37, 2.48). Communication frequency (1=not at all; 4=a lot) was significantly increased at follow-up (1.67 vs. 1.54). Differences were not modified by age, race, education, or family history. However, effects were modified by pregnancy status and genetic literacy. Intervention effects for information gathering and frequency were observed for nonpregnant women but not for pregnant women. Additionally, intervention effects were observed for information gathering in women with high genetic literacy, but not in women with low genetic literacy. The KinFact intervention successfully promoted family communication about cancer risk. Educating women to enhance their communication skills surrounding family history may allow them to partner more effectively with their families and ultimately

Breast cancer is the most common cancer among women and is the second cancer frequently occurring worldwide of newly-diagnosed cancers. There is much evidence showing the influence of life style and environmental factors on the development of mammary gland cancer (high-fat diet, alcohol consumption, lack of physical exercise), the elimination of which (primary prevention) may contribute to a decrease in morbidity and mortality. Secondary prevention, comprising diagnostic tests (e.g. mammography, ultrasonography, magnetic resonance imaging, breast self-examination, as well as modern and more precise imaging methods) help the early detection of tumours or lesions predisposing to tumours. The aim of this study paper is to review current knowledge and reports regarding primary and secondary prevention of breast cancer. It is estimated that nearly 70% of malign tumours are caused by environmental factors, whereas in breast cancer this percentage reaches 90-95%. There are national programmes established in many countries to fight cancer, where both types of prevention are stressed as serving to decrease morbidity and mortality due to cancers. Cancer prevention is currently playing a key role in the fight against the disease. Behaviour modification, as well as greater awareness among women regarding breast cancer, may significantly contribute towards reducing the incidence of this cancer. Another important aspect is the number of women undergoing diagnostic tests, which still remains at an unsatisfactory level.

Flavin-Dependent Enzymes in Cancer Prevention

Directory of Open Access Journals (Sweden)

Danuta Wojcieszyńska

2012-12-01

Full Text Available Statistical studies have demonstrated that various agents may reduce the risk of cancer’s development. One of them is activity of flavin-dependent enzymes such as flavin-containing monooxygenase (FMOGS-OX1, FAD-dependent 5,10-methylenetetrahydrofolate reductase and flavin-dependent monoamine oxidase. In the last decade, many papers concerning their structure, reaction mechanism and role in the cancer prevention were published. In our work, we provide a more in-depth analysis of flavin-dependent enzymes and their contribution to the cancer prevention. We present the actual knowledge about the glucosinolate synthesized by flavin-containing monooxygenase (FMOGS-OX1 and its role in cancer prevention, discuss the influence of mutations in FAD-dependent 5,10-methylenetetrahydrofolate reductase on the cancer risk, and describe FAD as an important cofactor for the demethylation of histons. We also present our views on the role of riboflavin supplements in the prevention against cancer.

Clinical practice guidelines provide separate recommendations for different diseases that may be prevented or treated by the same intervention. Also, they commonly provide recommendations for entire populations but not for individuals. To address these two limitations, our aim was to conduct benefit-harm analyses for a wide range of individuals using the example of low dose aspirin for primary prevention of cardiovascular disease and cancer and to develop Benefit-Harm Charts that show the overall benefit-harm balance for individuals. We used quantitative benefit-harm modeling that included 16 outcomes to estimate the probability that low dose aspirin provides more benefits than harms for a wide range of men and women between 45 and 84 years of age and without a previous myocardial infarction, severe ischemic stroke, or cancer. We repeated the quantitative benefit-harm modeling for different combinations of age, sex, and outcome risks for severe ischemic and hemorrhagic stroke, myocardial infarction, cancers, and severe gastrointestinal bleeds. The analyses considered weights for the outcomes, statistical uncertainty of the effects of aspirin, and death as a competing risk. We constructed Benefit-Harm Charts that show the benefit-harm balance for different combinations of outcome risks. The Benefit-Harm Charts ( http://www.benefit-harm-balance.com ) we have created show that the benefit-harm balance differs largely across a primary prevention population. Low dose aspirin is likely to provide more benefits than harms in men, elderly people, and in those at low risk for severe gastrointestinal bleeds. Individual preferences have a major impact on the benefit-harm balance. If, for example, it is a high priority for individuals to prevent stroke and severe cancers while severe gastrointestinal bleeds are deemed to be of little importance, the benefit-harm balance is likely to favor low dose aspirin for most individuals. Instead, if severe gastrointestinal bleeds are

Over 70% of human cancers are associated with lifestyle and about half of cancer deaths could be prevented by relatively simple individual actions: no smoking, moderate consumption of alcohol, increased consumption of fruit and vegetables, avoidance of sunbathing, obesity and a too high consumption of saturated lipids. Most of these efforts would also markedly decrease the incidence of cardiovascular and respiratory diseases. However, the concept of prevention is currently neither well accepted nor understood by the medical community and the general public. It is often felt that it restricts freedom, imposes a choice between pleasure and duty, and that passing judgement on lifestyle is a form of intolerance. The case of tobacco illustrates the difficulties encountered by prevention, notably among adolescents. The fight against smoking requires information, a societal approach (ban on advertising, increase in price), and a reduction of the example given by adult smoking (parents, peers, teachers, physicians, TV presenters, movie stars, have a great influence on adolescents), while tobacco cessation programs must be promoted. The various approaches should be integrated into a global program of health prevention, including health education at school from 5 to 12 years of age. The efficacy of each of the global program's components should be evaluated. Misconceptions such as overestimation of the impact of pollution on health should also be corrected. Health is created and experienced by people within the setting of their daily lives, in particular during childhood. Prevention is the responsibility of individual members of the community but also of the community as a whole.

Nutritional Interventions in Head and Neck Cancer Patients Undergoing Chemoradiotherapy: A Narrative Review

Directory of Open Access Journals (Sweden)

Maurizio Bossola

2015-01-01

Full Text Available The present review aimed to define the role of nutritional interventions in the prevention and treatment of malnutrition in HNC patients undergoing CRT as well as their impact on CRT-related toxicity and survival. Head and neck cancer patients are frequently malnourished at the time of diagnosis and prior to the beginning of treatment. In addition, chemo-radiotherapy (CRT causes or exacerbates symptoms, such as alteration or loss of taste, mucositis, xerostomia, fatigue, nausea and vomiting, with consequent worsening of malnutrition. Nutritional counseling (NC and oral nutritional supplements (ONS should be used to increase dietary intake and to prevent therapy-associated weight loss and interruption of radiation therapy. If obstructing cancer and/or mucositis interfere with swallowing, enteral nutrition should be delivered by tube. However, it seems that there is not sufficient evidence to determine the optimal method of enteral feeding. Prophylactic feeding through nasogastric tube or percutaneous gastrostomy to prevent weight loss, reduce dehydration and hospitalizations, and avoid treatment breaks has become relatively common. Compared to reactive feeding (patients are supported with oral nutritional supplements and when it is impossible to maintain nutritional requirements enteral feeding via a NGT or PEG is started, prophylactic feeding does not offer advantages in terms of nutritional outcomes, interruptions of radiotherapy and survival. Overall, it seems that further adequate prospective, randomized studies are needed to define the better nutritional intervention in head and neck cancer patients undergoing chemoradiotherapy.

Among the most prevalent and distressing concerns endorsed by breast cancer survivors is fear of cancer recurrence (FOR), and one of the most salient facets is the worry that a recurrence of cancer could cause one's death. The primary goal of the present study was to test the effects of a brief, low-cost gratitude intervention on overall FOR and death-related FOR, positing pursuit of meaningful goals as a theoretically driven putative mediator. To replicate published tests of similar gratitude-eliciting interventions, positive affect (PA) was also considered as an outcome. Sixty-seven women with early stage breast cancer were randomly assigned to either a 6-week online gratitude intervention or a 6-week online control condition. Outcomes were assessed at pre- and posttreatment, as well as 1 month and 3 months after the end of treatment. The mediator, meaningful goal pursuit, was measured via assessments over the 6-week intervention period. Results revealed that patients in the gratitude intervention experienced a significant decrease in death-related FOR compared to the control condition. Moreover, this effect was significantly mediated by meaningful goal pursuit (and not by PA). The gratitude intervention was also found to prevent declines in PA observed in the control condition. Overall, findings support the notion that a brief gratitude intervention can promote well-being and psychological adaptation to cancer by stimulating the pursuit of meaningful goals and subsequently reducing death-related FOR.

Purpose: Human Papillomavirus (HPV) has been identified as a causal agent for oropharyngeal cancers, suggesting a new role for dental hygienists in HPV-related cancer prevention strategies. Health literacy assessment is an approach that can be used to understand providers' informational assets and needs for educating and discussing HPV prevention with patients. This study aimed to understand dental hygienists' level of health literacy regarding HPV-related oropharyngeal cancers. Methods: Four focus group sessions with dental hygienists (n=48) were conducted at a national conference. The constant comparison method, with a priori codes for health literacy competencies (i.e., access/understand/appraise/apply), was utilized for this qualitative study. Results: Participants mentioned a variety of modes (e.g., magazines, journals) for accessing HPV-information; however, descriptions of understanding HPV and its relationship to oropharyngeal cancer varied. Participants considered patients' personal characteristics, the dental practice environment, and professional factors to appraise HPV-related information. Additionally, participants self-described themselves as being "prevention specialists." These factors influenced how dental hygienists applied primary and secondary prevention of HPV-related care issues with their patients (e.g., education and oral-cancer screenings). Conclusions: Dental hygienists recognized the importance of HPV and oropharyngeal cancer prevention efforts, including oral-cancer screenings and promotion of the HPV vaccine. The study findings identified opportunities for intervention focusing on primary prevention. Copyright © 2017 The American Dental Hygienists’ Association.

Full Text Available Starting with patient’ diagnose and continuing throughout the treatment and thereafter, cancer-related fatigue (CRF is a distressing and disabling symptom, highly prevalent across the cancer continuum2. This is a review article mainly focusing on the rehabilitation objectives and interventions in CRF, and implementation issues, according to the report of an NCCN member institution4. Implementation is the most problematic, considering the large number of patients to whom it is addressed to and the variety of pathologies within this group of patients. The onset of CRF is difficult to establish, because of the limitations of reporting this symptom4, but it is a valuable predictor in prognosis. The main interventions in rehabilitation applicable to these patients are discussed in correlation to the objectives of each phase of therapeutic management in cancer: pre-operatory, before, during or after radio and/or chemotherapy Conclusion: Rehabilitation interventions should be applied to all patients diagnosed with cancer, according to their phase of oncologic treatment and the objectives. This should be practiced as preventive measure, but as a therapeutic one to, considering the high incidence of CFR before diagnose.

Health psychology and translational genomic research: bringing innovation to cancer-related behavioral interventions.

McBride, Colleen M; Birmingham, Wendy C; Kinney, Anita Y

2015-01-01

The past decade has witnessed rapid advances in human genome sequencing technology and in the understanding of the role of genetic and epigenetic alterations in cancer development. These advances have raised hopes that such knowledge could lead to improvements in behavioral risk reduction interventions, tailored screening recommendations, and treatment matching that together could accelerate the war on cancer. Despite this optimism, translation of genomic discovery for clinical and public health applications has moved relatively slowly. To date, health psychologists and the behavioral sciences generally have played a very limited role in translation research. In this report we discuss what we mean by genomic translational research and consider the social forces that have slowed translational research, including normative assumptions that translation research must occur downstream of basic science, thus relegating health psychology and other behavioral sciences to a distal role. We then outline two broad priority areas in cancer prevention, detection, and treatment where evidence will be needed to guide evaluation and implementation of personalized genomics: (a) effective communication, to broaden dissemination of genomic discovery, including patient-provider communication and familial communication, and (b) the need to improve the motivational impact of behavior change interventions, including those aimed at altering lifestyle choices and those focusing on decision making regarding targeted cancer treatments and chemopreventive adherence. We further discuss the role that health psychologists can play in interdisciplinary teams to shape translational research priorities and to evaluate the utility of emerging genomic discoveries for cancer prevention and control.

Cancer prevention in Africa: a review of the literature.

Science.gov (United States)

Busolo, David S; Woodgate, Roberta L

2015-06-01

Cancer is an emerging crisis in Africa. Cancer was the seventh leading cause of death in 2004. If not controlled, cancer incidence in Africa is expected to reach 1.28 million cases annually and claim 970,000 lives yearly by 2030. This paper presents a review of the literature on current cancer prevention approaches in Africa, and consists of cancer prevention studies conducted in African countries (e.g. South Africa and Nigeria) from PubMed, Scopus, and CINAHL databases. Common female cancers in Africa are breast and cervical cancer while prostate cancer is the most common neoplasm among African males. Other common cancers are liver, colorectal, and non-Hodgkin's lymphoma. Mortality related to these cancers comes as a result of delays in screening and treatment, unfamiliarity with cancer and cancer prevention, inaccessibility and unaffordability of care, and inefficiency of healthcare systems. Cancer prevention efforts are deficient because many governments lack cancer prevention and control policies. Also contributing to the lack of cancer prevention and control policies are low levels of awareness, scarce human and financial resources, and inadequacy of cancer registries. Overall, governments grapple with limited funds and competing healthcare priorities. As cancer continues to increase in Africa, the need for rigorous interdisciplinary research on cancer etiology and monitoring in Africa has never been timelier. Cost-effective cancer prevention programs, coordination of donor funding, advocacy, and education should be aggressively pursued. The call for more collaborative approaches in research and policy is urgently needed. © The Author(s) 2014.

Cancers constitute a significant public health problem in Nigeria. Breast, cervix and prostate cancers are leading causes of cancer-related deaths. Changing diets, lifestyles, HIV/AIDS and macro-structural factors contribute to cancer morbidity and mortality. Poor health information linking cancer risk to individual behaviors, environmental pollutants and structural barriers undermine prevention/control efforts. Studies suggest increasing health literacy and empowering individuals to take preventive action will improve outcomes and mitigate impact on a weak health system. We obtained qualitative data from 80 men, women, and young adults in 11 focus groups to assess beliefs, risk-perceptions, preventive behaviors and perceptions of barriers and facilitators to cancer control in Ibadan, Nigeria and conducted thematic analysis. Participants demonstrated awareness of cancers and mentioned several risk factors related to individual behaviors and the environment. Nonetheless, myths and misconceptions as well as micro, meso and macro level barriers impede prevention and control efforts. Developing and implementing comprehensive context-relevant health literacy interventions in community settings are urgently needed.Copyright © 2016 John Wiley & Sons, Ltd.

There is increasing interest in complementary and holistic approaches for cancer prevention and management. We sought to review the latest literature regarding dietary interventions for prostate cancer with a special emphasis on dietary fat and carbohydrate intake for modulating prognosis among men with prostate cancer. Several recent prospective trials have investigated various dietary and lifestyle investigations on malignant prostate tissue biology. These interventions included a very low-fat (12% fat kcals) vegan diet with various supplements and lifestyle changes, a more traditional low-fat diet (25% fat kcals) with flaxseed supplementation, and a low-glycemic index diet. Low-glycemic index and very low-fat vegan diets (with supplements and lifestyle changes) alter tumor biology as assessed by tumor gene expression changes, with a common mechanism perhaps being weight loss whereas no effects were seen with a traditional low-fat diet. In mice, either very low-fat or low-carbohydrate diets significantly slow tumor growth independent of weight loss. Epidemiologic and preclinical data also suggest cholesterol intake and serum cholesterol levels may be linked with the development and progression of prostate cancer. Small clinical trials suggest that tumor biology can be altered by either a vegan low-fat diet or eliminating simple carbohydrates accompanied by weight loss. Larger and longer term studies are needed to determine the clinical relevance of these findings.

Background The incidence of melanoma is increasing faster than any other major cancer both in Brazil and worldwide. Southeast Brazil has especially high incidences of melanoma, and early detection is low. Exposure to ultraviolet (UV) radiation is a primary risk factor for developing melanoma. Increasing attractiveness is a major motivation among adolescents for tanning. A medical student-delivered intervention that takes advantage of the broad availability of mobile phones and adolescents’ interest in their appearance indicated effectiveness in a recent study from Germany. However, the effect in a high-UV index country with a high melanoma prevalence and the capability of medical students to implement such an intervention remain unknown. Objective In this pilot study, our objective was to investigate the preliminary success and implementability of a photoaging intervention to prevent skin cancer in Brazilian adolescents. Methods We implemented a free photoaging mobile phone app (Sunface) in 15 secondary school classes in southeast Brazil. Medical students “mirrored” the pupils’ altered 3-dimensional (3D) selfies reacting to touch on tablets via a projector in front of their whole grade accompanied by a brief discussion of means of UV protection. An anonymous questionnaire capturing sociodemographic data and risk factors for melanoma measured the perceptions of the intervention on 5-point Likert scales among 356 pupils of both sexes (13-19 years old; median age 16 years) in grades 8 to 12 of 2 secondary schools in Brazil. Results We measured more than 90% agreement in both items that measured motivation to reduce UV exposure and only 5.6% disagreement: 322 (90.5%) agreed or strongly agreed that their 3D selfie motivated them to avoid using a tanning bed, and 321 (90.2%) that it motivated them to improve their sun protection; 20 pupils (5.6%) disagreed with both items. The perceived effect on motivation was higher in female pupils in both tanning bed

Cancer is a leading cause of death worldwide, accounting for approximately 7.6 million deaths (13% of all deaths) in 2008. Cancer mortality is projected to increase to 11 million deaths in 2030, with the majority occurring in regions of the world with the least capacity to respond. However, cancer is not only a personal, societal and economic burden but also a potential societal opportunity in the context of functional life - the years gained through effective prevention and treatment, and strategies to enhance survivorship. The United Nations General Assembly Special Session in 2011 has served to focus attention on key aspects of cancer prevention and control. Firstly, cancer is largely preventable, by feasible means. Secondly, cancer is one of a number of chronic, non- communicable diseases that share common risk factors whose prevention and control would benefit a majority of the world's population. Thirdly, a proportion of cancers can be attributed to infectious, communicable causal factors (e.g., HPV, HBV, H.pylori, parasites, flukes) and that strategies to control the burden of infectious diseases have relevance to the control of cancer. Fourthly, that the natural history of non-communicable diseases, including cancer, from primary prevention through diagnosis, treatment and care, is underwritten by the impact of social, economic and environmental determinants of health (e.g., poverty, illiteracy, gender inequality, social isolation, stigma, socio-economic status). Session 1 of the 4th International Cancer Control Congress (ICCC-4) focused on the social, economic and environmental, as well as biological and behavioural, modifiers of the risk of cancer through one plenary presentation and four interactive workshop discussions. The workshop sessions concerned 1) the Global Adult Tobacco Survey and social determinants of tobacco use in high burden low- and middle-income countries; 2) the role of diet, including alcohol, and physical activity in modifying the

Full Text Available Abstract Background To achieve widespread cancer control, a better understanding is needed of the factors that contribute to successful implementation of effective skin cancer prevention interventions. This study assessed the relative contributions of individual- and setting-level characteristics to implementation of a widely disseminated skin cancer prevention program. Methods A multilevel analysis was conducted using data from the Pool Cool Diffusion Trial from 2004 and replicated with data from 2005. Implementation of Pool Cool by lifeguards was measured using a composite score (implementation variable, range 0 to 10 that assessed whether the lifeguard performed different components of the intervention. Predictors included lifeguard background characteristics, lifeguard sun protection-related attitudes and behaviors, pool characteristics, and enhanced (i.e., more technical assistance, tailored materials, and incentives are provided versus basic treatment group. Results The mean value of the implementation variable was 4 in both years (2004 and 2005; SD = 2 in 2004 and SD = 3 in 2005 indicating a moderate implementation for most lifeguards. Several individual-level (lifeguard characteristics and setting-level (pool characteristics and treatment group factors were found to be significantly associated with implementation of Pool Cool by lifeguards. All three lifeguard-level domains (lifeguard background characteristics, lifeguard sun protection-related attitudes and behaviors and six pool-level predictors (number of weekly pool visitors, intervention intensity, geographic latitude, pool location, sun safety and/or skin cancer prevention programs, and sun safety programs and policies were included in the final model. The most important predictors of implementation were the number of weekly pool visitors (inverse association and enhanced treatment group (positive association. That is, pools with fewer weekly visitors and pools in the enhanced

New cancer cases are expected to surge 57% worldwide in the next two decades. The greatest burden will be in low- and middle-income countries that are ill equipped to face this epidemic. Similarly, in the United States, low-income populations are at greater risk for cancer. As most cancers contain over 50 genetic alterations, and as these alterations define dysregulation of over 10 different critical cellular signaling pathways, a "silver bullet" treatment is not effective against most cancers. Instead, the latest World Cancer Report (2012) suggests a research shift toward developing prevention strategies for cancer. Accumulating evidence suggests that a diet high in plant-based foods is preventive of a variety of chronic diseases, including cancer. A plethora of bioactive compounds-such as polyphenols, glucosinolates and carotenoids in fruits, vegetables, grains, and legumes-are shown to suppress a variety of biological capabilities required for tumor growth. While much research has shown that plant bioactive compounds can suppress sustained proliferative signaling, angiogenesis, and metastasis, as well as promote cancer stem cell apoptosis, public health campaigns to increase fruit and vegetable consumption have, overall, been less effective than desired. Thus, there is a need for innovative strategies to support increased consumption of bioactive compounds for cancer prevention particularly in vulnerable populations. Many practices of the farm-to-fork continuum, including preharvest practices, postharvest storage, and processing and consumer practices, affect a food's bioactive compound content, composition, and chemopreventive bioactivity. Food system practices may be adjusted to reduce the toxic compound levels (e.g., glycoalkaloids in potatoes) and improve the bioactive compound profile, thus, elevate the cancer fighting properties of fruits, vegetables, and other food products. This review presents current scientific evidence outlining farm-to-fork effects

Sestak, Ivana; Cuzick, Jack

Breast cancer is the most common cancer in women worldwide. This review will focus on current prevention strategies for women at high risk. The identification of women who are at high risk of developing breast cancer is key to breast cancer prevention. Recent findings have shown that the inclusion of breast density and a panel of low-penetrance genetic polymorphisms can improve risk estimation compared with previous models. Preventive therapy with aromatase inhibitors has produced large reductions in breast cancer incidence in postmenopausal women. Tamoxifen confers long-term protection and is the only proven preventive treatment for premenopausal women. Several other agents, including metformin, bisphosphonates, aspirin and statins, have been found to be effective in nonrandomized settings. There are many options for the prevention of oestrogen-positive breast cancer, in postmenopausal women who can be given a selective oestrogen receptor modulator or an aromatase inhibitor. It still remains unclear how to prevent oestrogen-negative breast cancer, which occurs more often in premenopausal women. Identification of women at high risk of the disease is crucial, and the inclusion of breast density and a panel of genetic polymorphisms, which individually have low penetrance, can improve risk assessment.

Objective: To evaluate the point plaster therapy with ginger powder combined with ondansetron hydrochloride in preventing nausea and vomiting usually occurred after platinum-based interventional chemotherapy in patients with primary or metastatic liver cancer, and to compared its effectiveness with that by using ondansetron hydrochloride only. Method: Sixty-two patients with primary or metastatic liver cancer, who were scheduled to receive platinum-based interventional chemotherapy, were randomly and equally divided into two groups with 31 cases in each group. The patients in the study group (n = 31) were given point plaster therapy, i.e. externally applying ginger powder (20 g) to the point of Shenque, for four days together with arterial infusion of ondansetron hydrochloride (8 mg) during interventional procedure,while the patients in the control group (n = 31) were given point plaster therapy with placebo (potato powder) together with arterial infusion of ondansetron hydrochloride (8 mg) during interventional procedure. The questionnaire of INVR (index form for evaluating nausea and vomiting) was used to assess the effectiveness, and the results were compared between two groups. Results: The incidence of nausea and vomiting in study group was significantly lower than that in control group at all observed points of time during the period of 0 -72 hours after the treatment (P 0.05). After the treatment the scores of nausea, vomiting and retching in the study group were 0.45, 0.25 and 0.19 respectively, while these in the control group were 2.77, 0.87 and 0.97 respectively, the differences between two groups were statistically significant (P < 0.05). Conclusion: The external application of ginger powder to points of Shenque can markedly decrease the incidence and severity of nausea and vomiting after platinum-based interventional chemotherapy in patients with primary or metastatic liver cancer.

Colorectal cancer is the third most commonly diagnosed cancer and the fourth leading cause of death in the world. There are few published studies that have used theory-based interventions designed to increase colorectal cancer screening in community lay health organizations. The present study was guided by the theoretical concepts of the preventive health model. Twelve health clubs of a municipal district in Tehran were randomized to two study groups with equal ratio. The control group received usual services throughout the study while the intervention group also received a theory-based educational program on colorectal cancer screening plus a reminder call. Screening behavior, the main outcome, was assessed 4 months after randomization. A total of 360 members aged 50 and older from 12 health clubs completed a baseline survey. Participants in the intervention group reported increased knowledge of colorectal cancer and screening tests at 4 months follow-up (p's theory-based intervention significantly improved self-efficacy, perceived susceptibility, efficacy of screening, social support, and intention to be screened for colorectal cancer, from baseline to 4 months follow-up (p's theory-based intervention was found to have a significant effect on colorectal cancer screening use as measured by self-report. The findings could have implications for colorectal cancer screening program development and implementation in primary health care settings and through other community organizations.

Despite the increasing breast cancer incidence and mortality rates, Korean American immigrant women have one of the lowest rates of breast cancer screening across racial groups in the United States. Mobile health (mHealth), defined as the delivery of health care information or services through mobile communication devices, has been utilized to successfully improve a variety of health outcomes. This study adapted the principles of mHealth to advance breast cancer prevention efforts among Korean American immigrant women, an underserved community. Using a randomized controlled trial design, 120 Korean American women aged 40 to 77 years were recruited and randomly assigned to either the mMammogram intervention group (n=60) to receive culturally and personally tailored multilevel and multimedia messages through a mobile phone app along with health navigator services or the usual care control group (n=60) to receive a printed brochure. Outcome measures included knowledge, attitudes, and beliefs about breast cancer screening, readiness for mammography, and mammogram receipt. The feasibility and acceptability of the mMammogram intervention was also assessed. The intervention group showed significantly greater change on scores of knowledge of breast cancer and screening guidelines (P=.01). The intervention group also showed significantly greater readiness for mammography use after the intervention compared with the control group. A significantly higher proportion of women who received the mMammogram intervention (75%, 45/60) completed mammograms by the 6-month follow-up compared with the control group (30%, 18/60; Pservice was a feasible, acceptable, and effective intervention mechanism to promote breast cancer screening in Korean American immigrant women. A flexible, easily tailored approach that relies on recent technological advancements can reach underserved and hard-to-recruit populations that bear disproportionate cancer burdens.

Hochberg, Uri; Elgueta, Maria Francisca; Perez, Jordi

2017-01-01

Lung cancer is one of the four most prevalent cancers worldwide. Comprehensive patient care includes not only adherence to clinical guidelines to control and when possible cure the disease but also appropriate symptom control. Pain is one of the most prevalent symptoms in patients diagnosed with lung cancer; it can arise from local invasion of chest structures or metastatic disease invading bones, nerves, or other anatomical structures potentially painful. Pain can also be a consequence of therapeutic approaches like surgery, chemotherapy, or radiotherapy. Conventional medical management of cancer pain includes prescription of opioids and coadjuvants at doses sufficient to control the symptoms without causing severe drug effects. When an adequate pharmacological medical management fails to provide satisfactory analgesia or when it causes limiting side effects, interventional cancer pain techniques may be considered. Interventional pain management is devoted to the use of invasive techniques such as joint injections, nerve blocks and/or neurolysis, neuromodulation, and cement augmentation techniques to provide diagnosis and treatment of pain syndromes resistant to conventional medical management. Advantages of interventional approaches include better analgesic outcomes without experiencing drug-related side effects and potential for opioid reduction thus avoiding central side effects. This review will describe various pain syndromes frequently described in lung cancer patients and those interventional techniques potentially indicated for those cases.

Poor voice quality due to a voice disorder can lead to a reduced quality of life. In occupations where voice use is substantial it can lead to periods of absence from work. To evaluate the effectiveness of interventions to prevent voice disorders in adults. We searched MEDLINE (PubMed, 1950 to 2006), EMBASE (1974 to 2006), CENTRAL (The Cochrane Library, Issue 2 2006), CINAHL (1983 to 2006), PsychINFO (1967 to 2006), Science Citation Index (1986 to 2006) and the Occupational Health databases OSH-ROM (to 2006). The date of the last search was 05/04/06. Randomised controlled clinical trials (RCTs) of interventions evaluating the effectiveness of treatments to prevent voice disorders in adults. For work-directed interventions interrupted time series and prospective cohort studies were also eligible. Two authors independently extracted data and assessed trial quality. Meta-analysis was performed where appropriate. We identified two randomised controlled trials including a total of 53 participants in intervention groups and 43 controls. One study was conducted with teachers and the other with student teachers. Both trials were poor quality. Interventions were grouped into 1) direct voice training, 2) indirect voice training and 3) direct and indirect voice training combined.1) Direct voice training: One study did not find a significant decrease of the Voice Handicap Index for direct voice training compared to no intervention.2) Indirect voice training: One study did not find a significant decrease of the Voice Handicap Index for indirect voice training when compared to no intervention.3) Direct and indirect voice training combined: One study did not find a decrease of the Voice Handicap Index for direct and indirect voice training combined when compared to no intervention. The same study did however find an improvement in maximum phonation time (Mean Difference -3.18 sec; 95 % CI -4.43 to -1.93) for direct and indirect voice training combined when compared to no

Full Text Available BACKGROUND: This study aimed to explore the effectiveness of the cyber bullying prevention WebQuest course implementation. METHODOLOGY/FINDINGS: The study adopted the quasi-experimental design with two classes made up of a total of 61 junior high school students of seventh grade. The study subjects comprised of 30 students from the experimental group and 31 students from the control group. The experimental group received eight sessions (total 360 minutes of the teaching intervention for four consecutive weeks, while the control group did not engage in any related courses. The self-compiled questionnaire for the student's knowledge, attitudes, and intentions toward cyber bullying prevention was adopted. Data were analysed through generalized estimating equations to understand the immediate results on the student's knowledge, attitudes, and intentions after the intervention. The results show that the WebQuest course immediately and effectively enhanced the knowledge of cyber bullying, reduced the intentions, and retained the effects after the learning. But it produced no significant impact on the attitude toward cyber bullying. CONCLUSIONS/SIGNIFICANCE: The intervention through this pilot study was effective and positive for cyber bulling prevention. It was with small number of students. Therefore, studies with large number of students and long experimental times, in different areas and countries are warranted.

H. pylori infection causes gastritis, peptic ulcers and gastric cancer. Eradicating H. pylori prevents ulcers, but to what extent this prevents cancer remains unknown, especially if given after intestinal metaplasia has developed. H. pylori infected wild-type (WT) mice do not develop cancer, but mice lacking the tumor suppressor p27 do so, thus providing an experimental model of H. pylori-induced cancer. We infected p27-deficient mice with H. pylori strain SS1 at 6-8 weeks of age. Persistently H. pylori-infected WT C57BL/6 mice served as controls. Mice in the eradication arms received antimicrobial therapy (omeprazole, metronidazole and clarithromycin) either "early" (at 15 weeks post infection, WPI) or "late" at 45 WPI. At 70 WPI, mice were euthanized for H. pylori determination, histopathology and cytokine/chemokine expression. Persistently infected mice developed premalignant lesions including high-grade dysplasia, whereas those given antibiotics did not. Histologic activity scores in the eradication groups were similar to each other, and were significantly decreased compared with controls for inflammation, epithelial defects, hyperplasia, metaplasia, atrophy and dysplasia. IP-10 and MIG levels in groups that received antibiotics were significantly lower than controls. There were no significant differences in expression of IFN-γ, TNF-α, IL-1β, RANTES, MCP-1, MIP-1α or MIP-1β among the three groups. Thus, H. pylori eradication given either early or late after infection significantly attenuated gastric inflammation, gastric atrophy, hyperplasia, and dysplasia in the p27-deficient mice model of H. pylori-induced gastric cancer, irrespective of the timing of antibiotic administration. This was associated with reduced expression of IP-10 and MIG. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Epigenetic changes in DNA and associated chromatin proteins are increasingly being considered as important mediators of the linkage between obesity and cancer. Although multiple agents, targeted at epigenetic changes, are being tested for therapy of established cancers, this issue of Cancer Prevention Research carries two articles demonstrating that the bromodomain inhibitor I-BET-762 can attenuate adipose tissue-promoted cancers. Although I-BET-762 significantly delayed, rather than completely prevented, the onset of adiposity-promoted transformation and malignancy, these experiments provide important proof of principle for the strategies of targeting epigenetic changes to disrupt the obesity-cancer linkage. Because bromodomain proteins represent only one of multiple epigenetic mediators, it is probable that targeting other epigenetic processes, alone or in combination, may serve to even more effectively disrupt the obesity promotion of cancer. Given the magnitude of the current obesity pandemic and its impact on cancer, preventive measures to disrupt this linkage are critically important.

Possibilities for the prevention of cancer

International Nuclear Information System (INIS)

Doll, Richard

1986-01-01

Two types of evidence suggest that the prevention of cancer is a practical possibility: first, our increasing knowledge of the causes of cancer, many of which can be avoided without difficulty, and second, evidence that all common cancers whose causes are still unknown vary in incidence with place, time or social group. Many known causes still exist, however, and are responsible for hundreds of thousands of cases annually throughout the world. Practical possibilities for prevention now and in the near future include changes in personal habits (tobacco, alcohol, diet), control of exposure to known cancer-producing substances (carcinogens) in both industry and the general environment, and immunization against viruses causing cancer.

Decisions to smoke are made within a broad social context. Community interventions use co-ordinated, widespread, multi-component programmes to try and influence behaviour. To determine the effectiveness of community interventions in preventing the uptake of smoking in young people. The Tobacco Addiction group specialised register, Medline and other health, psychology and public policy electronic databases were searched, the bibliographies of identified studies were checked and contact was made with content area specialists. Searches were updated in September 2002. Randomised and non randomised controlled trials that assessed the effectiveness of multi-component community interventions compared to no intervention or to single component or school-based programmes only. Reported outcomes had to include smoking behaviour in young people under the age of 25 years. Information relating to the characteristics and the content of community interventions, participants, outcomes and methods of the study was extracted by one reviewer and checked by a second. Studies were combined using qualitative narrative synthesis. Seventeen studies were included in the review, 46 studies did not meet all of the inclusion criteria. All studies used a controlled trial design, with six using random allocation of schools or communities. Of thirteen studies which compared community interventions to no intervention controls, two, which were part of cardiovascular disease prevention programmes, reported lower smoking prevalence. Of three studies comparing community interventions to school-based programmes only, one found differences in reported smoking prevalence. One study reported a lower rate of increase in prevalence in a community receiving a multi-component intervention compared to a community exposed to a mass media campaign alone. One study reported a significant difference in smoking prevalence between a group receiving a media, school and homework intervention compared to a group

Full Text Available Objective: The aim of this study was to determine the awareness about skin cancer, prevention, and early detection among university students. Methods: This descriptive cross-sectional study was carried out with 404 students in a university located in Ankara, the capital city of Turkey. A 35-item questionnaire was used for data collection. Results: Less than half of the students (37.9% had knowledge about skin cancer mostly through the internet (24.5% and media (24.1%. Half of them aware of the risk factors; mostly as avoiding direct exposure to the Sun between 10 am and 4 pm (45.3%; smoking and alcohol (38.4%; having fair skin color (34.9%; and ultraviolet light exposure (25.7%. Only one-third of them (32.9% are knowledgeable about skin cancer signs and symptoms, such as a change in color and appearance of the nevus/moles (24%. The majority of the responders (77.3% did not know about screening tests for skin cancer and only 18 (4.5% students were practicing skin self-examination. Conclusions: This study showed a lack of knowledge about skin cancer, prevention, and early detection among university students and reported the need for educational interventions to raise awareness in this target group.

Federal structures and associated behavioural interventions in prevention of cigarette smoking

2008-10-01

Full Text Available Objectives: The recently published HTA-report “Effectiveness and cost-effectiveness of behavioural strategies in the prevention of cigarette smoking” detects a lack of high-quality publications considering the national prevention structures. Included publications do not give any information regarding current interventions in Germany. The goal of this addendum is to give an overview of the federal prevention system and associated measures for behavioural smoking prevention. Methods: Firstly, relevant tobacco prevention structures with associated tasks and activities were identified. Further, a survey of available project information was conducted in December 2007. This procedure based on systematic analysis in PrevNet-network as well as on manual search on the web sites of primary network centres (PrevNet-Knotenpunkte or other relevant federal state organisations. A written, postal questionnaire was conducted among network centres, federal state organisations and selected health insurance funds. Results: Interventions regarding primary prevention of smoking cover a variety of activities and campaigns issued by the Federal Government, several national organisations, federal and local authorities as well as health insurance funds. Institutions such as the German Ministry of Health, the Federal Centre for Health Education (BZGA, the German Cancer Research Center (DKFZ contribute to smoking prevention on national level. Diverse professional associations, workshops or authorities set up the organisational framework for coordination and planning of tobacco prevention on federal state level. Even on communal level institutional structures in terms of local professional departments and committees are established. The health insurance companies and their associations also play a major role in prevention of smoking uptake. “Rauchfrei”, “Be smart, don´ t start”, “Klasse 2000”, “ALF” or “Just be smokefree” are among the most well

2015-01-01

The benefits associated with some cancer treatments do not come without risk. A serious side effect of some common cancer treatments is cardiotoxicity. Increased recognition of the public health implications of cancer treatment-induced cardiotoxicity has resulted in a proliferation of systematic reviews in this field to guide practice. Quality appraisal of these reviews is likely to limit the influence of biased conclusions from systematic reviews that have used poor methodology related to clinical decision-making. The aim of this meta-review is to appraise and synthesise evidence from only high quality systematic reviews focused on the prevention, detection or management of cancer treatment-induced cardiotoxicity. Using Cochrane methodology, we searched databases, citations and hand-searched bibliographies. Two reviewers independently appraised reviews and extracted findings. A total of 18 high quality systematic reviews were subsequently analysed, 67 % (n = 12) of these comprised meta-analyses. One systematic review concluded that there is insufficient evidence regarding the utility of cardiac biomarkers for the detection of cardiotoxicity. The following strategies might reduce the risk of cardiotoxicity: 1) The concomitant administration of dexrazoxane with anthracylines; 2) The avoidance of anthracyclines where possible; 3) The continuous administration of anthracyclines (>6 h) rather than bolus dosing; and 4) The administration of anthracycline derivatives such as epirubicin or liposomal-encapsulated doxorubicin instead of doxorubicin. In terms of management, one review focused on medical interventions for treating anthracycline-induced cardiotoxicity during or after treatment of childhood cancer. Neither intervention (enalapril and phosphocreatine) was associated with statistically significant improvement in ejection fraction or mortality. This review highlights the lack of high level evidence to guide clinical decision-making with respect to the detection

2010-01-01

Aims To develop and test cancer prevention messages based on Prospect theory on motivation to improve dietary intake in African American adolescents, and to explore other salient factors that may inform dietary intervention design and implementation in this population. Methods Semi-structured in-person qualitative interviews were conducted with 13 African-American male and female adolescents, 12-16 years, in North Carolina. Prospect theory and message framing were used to guide the design of the four sets of diet-related messages related to cancer prevention: short-term gain-, long-term gain-, short-term loss-, and long-term loss-framed messages. Data were also collected on demographic, behavioral, and psychological factors; usual health behaviors; and preferences for intervention delivery. Results The majority of respondents found the gain-framed, short-term messages most salient for both fruits/vegetables (8 (61.5%)), and fat consumption (7 (53.8%)). For fat consumption only, 2 (15.4%) found the loss-framed, short-term messages pertinent; none found the loss-framed, long-term messages relevant for either dietary variable. All indicated interest in participating in a dietary intervention/education program; most preferred the Internet as a channel for intervention delivery. Participants expressed diverse views regarding knowledge, attitudes, and beliefs regarding healthy eating. Conclusions Researchers conducting dietary interventions and education initiatives and medical professionals who counsel African American adolescents should consider using Prospect Theory as a theoretical framework, should focus on gain-framed short-term messages regarding cancer prevention, and should employ the Internet for data collection and intervention and information delivery.

White Mary C

2011-06-01

Full Text Available Abstract Background Diet is thought to play an important role in cancer risk. This paper summarizes dietary recommendations for cancer prevention and compares these recommendations to the dietary behaviors of U.S. youth ages 8-18. Methods We identified cancer prevention-related dietary recommendations from key health organizations and assessed dietary consumption patterns among youth using published statistics from the National Health and Nutrition Examination Survey, the national Youth Risk Behavior Survey, and other supplemental sources. Results Cancer prevention guidelines recommend a diet rich in fruits, vegetables, and whole grains, recommend limiting sugary foods and beverages, red and processed meats, sodium, and alcohol, and recommend avoiding foods contaminated with carcinogens. However, youth typically do not meet the daily recommendations for fruit, vegetable, or whole grain consumption and are over-consuming energy-dense, sugary and salty foods. Conclusions A large discrepancy exists between expert recommendations about diet and cancer and actual dietary practices among young people and points to the need for more research to better promote the translation of science into practice. Future research should focus on developing and evaluating policies and interventions at the community, state and national levels for aligning the diets of youth with the evolving scientific evidence regarding cancer prevention.

Abstract The prevention of the infectious diseases was accomplished long before there was any understanding of the molecular biology of bacteria and viruses. As for cancer, the sharp drop in frequency of the once-commonest lethal cancer, stomach cancer, was achieved without any contribution from biological research, and the current drop in lung cancer is the end-result of the observation by epidemiologists that most lung cancer is caused by smoking. So the basis for both these triumphs was es...

Positive psychology interventions in breast cancer. A systematic review.

2014-01-01

Positive psychology is an emerging area of empirical study, not only in clinical, but also in health psychology. The present systematic review aims to synthesize the evidence about the positive psychology interventions utilized in breast cancer. Relevant studies were identified via Pubmed, PsycINFO, Web of Science, Scopus, Cochrane, CINAHL, Wiley Online Library, TDX, and DIALNET databases (up to April 2013). Only those papers focused on interventions related to positive psychology and carried out on breast cancer patients were included. Of the 7266 articles found through databases, 16 studies were finally included in this review. Five groups of therapies were found: mindfulness-based approaches, expression of positive emotions, spiritual interventions, hope therapy, and meaning-making interventions. These specific interventions promoted positive changes in breast cancer participants, such as enhanced quality of life, well-being, hope, benefit finding, or optimism. However, the disparity of the interventions and some methodological issues limit the outcomes. Some studies provided relevant evidence about the clear development of positive aspects from the breast cancer experience. Positive interventions applied to patients and survivors of breast cancer were found to be able to promote positive aspects. A global consensus of a positive therapies classification is needed to take one more step in structuring positive psychology. Copyright © 2013 John Wiley & Sons, Ltd.

The principal effect of Helicobacter pylori infection is lifelong chronic gastritis, affecting up to 20% of younger adults but 50% to 80% of adults born in resource-rich countries before 1950. We conducted a systematic overview, aiming to answer the following clinical question: What are the effects of H pylori eradication treatment on the risk of developing gastric cancer? We searched: Medline, Embase, The Cochrane Library, and other important databases up to July 2014 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). At this update, searching of electronic databases retrieved 208 studies. After deduplication and removal of conference abstracts, 166 records were screened for inclusion in the overview. Appraisal of titles and abstracts led to the exclusion of 124 studies and the further review of 42 full publications. Of the 42 full articles evaluated, one systematic review was added at this update. We performed a GRADE evaluation for two PICO combinations. In this systematic overview, we categorised the efficacy for one intervention based on information about the effectiveness and safety of H pylori eradication treatment for the prevention of gastric cancer.

This study aims to examine the effect of school-based preventive intervention on cannabis use in Czech adolescents with different levels of risk factors and provide evidence of its universality. A randomized controlled prevention trial with six waves was conducted over a period of 33 months. We used a two-level logistic random-intercept model for panel data; we first looked at the statistical significance of the effect of the intervention on cannabis use, controlling for the characteristics of the children and time dummies. Then we analyzed the effects of the interactions between the intervention and the characteristics of the children on cannabis use and related it to the definition of universal preventive interventions. The setting for the study was in basic schools in the Czech Republic in the years 2007-2010. A total of 1,874 sixth-graders (mean age 11.82 years) who completed the baseline testing. According to our results, the prevention intervention was effective. We found all the selected characteristics of the children to be relevant in relation to cannabis use, except their relationships with their friends. We showed empirically that the intervention is universal in two dimensions for the selected characteristics of the children. First, all adolescents who undergo the intervention are expected to benefit. Second, with respect to the effect of the intervention on cannabis use, the total level of individual risk of cannabis use is superior to the composition of the risk factors in the individual risk profile. We present indicative evidence that the drug prevention intervention may be considered a true universal preventive intervention.

The Carolina Framework for Cervical Cancer Prevention describes 4 main causes of cervical cancer incidence: human papillomavirus (HPV) infection, lack of screening, screening errors, and not receiving follow-up care. We present 2 applications of the Carolina Framework in which we identify high-need counties in North Carolina and generate recommendations for improving prevention efforts. We created a cervical cancer prevention need index (CCPNI) that ranked counties on cervical cancer mortality, HPV vaccine initiation and completion, Pap smear screening, and provision of Pap tests to rarely- or never-screened women. In addition, we conducted in-depth interviews with 19 key informants from programs and agencies involved in cervical cancer prevention in North Carolina. North Carolina's 100 counties varied widely on individual CCPNI components, including annual cervical cancer mortality (median 2.7/100,000 women; range 0.0-8.0), adolescent girls' HPV vaccine initiation (median 42%; range 15%-62%), and Pap testing in the previous 3 years among Medicaid-insured adult women (median 59%; range 40%-83%). Counties with the greatest prevention needs formed 2 distinct clusters in the northeast and south-central regions of the state. Interviews generated 9 recommendations to improve cervical cancer prevention in North Carolina, identifying applications to specific programs and policies in the state. This study found striking geographic disparities in cervical cancer prevention need in North Carolina. Future prevention efforts in the state should prioritize high-need regions as well as recommended strategies and applications in existing programs. Other states can use the Carolina Framework to increase the impact of their cervical cancer prevention efforts. Copyright © 2013 Elsevier Inc. All rights reserved.

Van Patten, Cheri L; de Boer, Johan G; Tomlinson Guns, Emma S

2008-12-01

We review the effect of diet and dietary supplement interventions on prostate cancer progression, recurrence and survival. A literature search was conducted in MEDLINE, EMBASE and CINAHL to identify diet and dietary supplement intervention studies in men with prostate cancer using prostate specific antigen or prostate specific antigen doubling time as a surrogate serum biomarker of prostate cancer recurrence and/or survival. Of the 32 studies identified 9 (28%) were randomized controlled trials and the focus of this review. In these studies men had confirmed prostate cancer and elevated or increasing prostate specific antigen. Only 1 trial included men with metastatic disease. When body mass index was reported, men were overweight or obese. A significant decrease in prostate specific antigen was observed in some studies using a low fat vegan diet, soy beverage or lycopene supplement. While not often reported as an end point, a significant increase in prostate specific antigen doubling time was observed in a study on lycopene supplementation. In only 1 randomized controlled trial in men undergoing orchiectomy was a survival end point of fewer deaths with lycopene supplementation reported. A limited number of randomized controlled trials were identified in which diet and dietary supplement interventions appeared to slow disease progression in men with prostate cancer, although results vary. Studies were limited by reliance on the surrogate biomarker prostate specific antigen, sample size and study duration. Well designed trials are warranted to expand knowledge, replicate findings and further assess the impact of diet and dietary supplement interventions on recurrence and treatment associated morbidities.

Increasing evidence suggests that Mediterranean Diet (MD) is correlated with reduced risk of breast cancer (BC) and cancer mortality, since it modifies patients' serum antioxidant capacity, body composition and biochemical parameters. The aim of the study was to investigate whether a dietary intervention based on MD has a beneficial effect on these factors. In this intervention study, seventy female BC survivors were randomly assigned to (1) the intervention group (personalized dietary intervention based on MD) and (2) the control group (received the updated American Cancer Society Guidelines on Nutrition and Physical Activity for Cancer Prevention and ad libitum diet). Both groups were assessed twice [beginning, end of study (after 6 months)] regarding their anthropometric and biochemical parameters, serum vitamin C, vitamin A, a-tocopherol and CoQ10 levels, dietary intake and adherence to MD. An additional intermediate analysis was conducted on participants' body composition and biochemical profile. Concerning the intervention group, body weight, body fat mass, waist circumference, body mass index as well as HDL-cholesterol were significantly decreased (P body weight, body fat mass and serum total cholesterol rose (P body composition, adherence to MD and glycemic profile of postmenopausal BC survivors.

Penile cancer: epidemiology, pathogenesis and prevention.

Penile cancer is a disease with a high morbidity and mortality. Its prevalence is relatively rare, but the highest in some developing countries. Insight into its precursor lesions, pathogenesis and risk factors offers options to prevent this potentially mutilating disease. This review presents an overview of the different histologically and clinically identified precursor lesions of penile cancer and discusses the molecular pathogenesis, including the role of HPV in penile cancer development. A systematic review of the literature evaluating penile carcinogenesis, risk factors and molecular mechanisms involved. Careful monitoring of men with lichen sclerosis, genital Bowen's disease, erythroplasia of Queyrat and bowenoid papulosis seems useful, thereby offering early recognition of penile cancer and, subsequently, conservative therapeutic options. Special attention is given to flat penile lesions, which contain high numbers of HPV. Their role in HPV transmission to sexual partners is highlighted, but their potential to transform as a precursor lesion into penile cancer has been unsatisfactorily explored. Further research should not only focus on HPV mediated pathogenic pathways but also on the non-HPV related molecular and genetic factors that play a role in penile cancer development. Options for prevention of penile cancer include (neonatal) circumcision, limitation of penile HPV infections (either by prophylactic vaccination or condom use), prevention of phimosis, treatment of chronic inflammatory conditions, limiting PUVA treatment, smoking cessation and hygienic measures.

Ionizing radiation and cancer prevention

International Nuclear Information System (INIS)

Hoel, D.G.

1995-01-01

Ionizing radiation long has been recognized as a cause of cancer. Among environmental cancer risks, radiation in unique in the variety of organs and tissues that it can affect. Numerous epidemiological studies with good dosimetry provide the basis for cancer risk estimation, including quantitative information derived from observed dose-response relationships. The amount of cancer attributable to ionizing radiation is difficult to estimate, but numbers such as 1 to 3% have been suggested. Some radiation-induced cancers attributable to ionizing radiation is difficult to estimate, but numbers such as 1 to 3% have been suggested. Some radiation-induced cancers attributable to naturally occurring exposures, such as cosmic and terrestrial radiation, are not preventable. The major natural radiation exposure, radon, can often be reduced, especially in the home, but not entirely eliminated. Medical use of radiation constitutes the other main category of exposure, radon, can often be reduced, especially in the home, but not entirely eliminated. Medical use of radiation constitutes the other main category of exposure; because of the importance of its benefits to one's health, the appropriate prevention strategy is to simply work to minimize exposures. 9 refs., 1 fig., 5 tabs

Women with a BRCA1 or BRCA2 mutation are at high risk for breast cancer and must make important decisions about breast cancer prevention and screening. In the current study, we report a multisite, randomized, controlled trial evaluating the effectiveness of a decision aid for breast cancer prevention in women with a BRCA mutation with no previous diagnosis of cancer. Within 1 month of receiving a positive BRCA result, women were randomized to receive either usual care (control group) or decision aid (intervention group). Participants were followed at 3, 6, and 12 months; were asked about preventive measures; and completed standardized questionnaires assessing decision making and psychosocial functioning. One hundred fifty women were randomized. Mean cancer-related distress scores were significantly lower in the intervention group compared with the control group at 6 months (P = 0.01) and at 12 months postrandomization (P = 0.05). Decisional conflict scores declined over time for both groups and at no time were there statistical differences between the two groups. The decision aid for breast cancer prevention in women with a BRCA1 or BRCA2 mutation is effective in significantly decreasing cancer-related distress within the year following receipt of positive genetic test results.Genet Med 19 3, 330-336.

To respond to the rapid surge in the incidence of suicide in Japan, which appears to be an ongoing trend, the Japanese Multimodal Intervention Trials for Suicide Prevention (J-MISP) have launched a multimodal community-based suicide prevention program, NOCOMIT-J. The primary aim of this study is to examine whether NOCOMIT-J is effective in reducing suicidal behavior in the community. This study is a community intervention trial involving seven intervention regions with accompanying control regions, all with populations of statistically sufficient size. The program focuses on building social support networks in the public health system for suicide prevention and mental health promotion, intending to reinforce human relationships in the community. The intervention program components includes a primary prevention measures of awareness campaign for the public and key personnel, secondary prevention measures for screening of, and assisting, high-risk individuals, after-care for individuals bereaved by suicide, and other measures. The intervention started in July 2006, and will continue for 3.5 years. Participants are Japanese and foreign residents living in the intervention and control regions (a total of population of 2,120,000 individuals).

As the emphasis on preventing obesity has grown, so have calls for interventions that extend beyond individual behaviors and address changes in environments and policies. Despite the need for policy action, little is known about policy approaches that are most effective at preventing obesity. The Centers for Disease Control and Prevention (CDC) and others are funding the implementation and evaluation of new obesity prevention policies, presenting a distinct opportunity to learn from these practice-based initiatives and build the body of evidence-based approaches. However, contributions from this policy activity are limited by the incomplete and inconsistent evaluation data collected on policy processes and outcomes. We present a framework developed by the CDC-funded Center of Excellence for Training and Research Translation that public health practitioners can use to evaluate policy interventions and identify the practice-based evidence needed to fill the gaps in effective policy approaches to obesity prevention.

The Community Preventive Services Task Force recommends combined diet and physical activity promotion programs for people at increased risk of type 2 diabetes, as evidence continues to show that intensive lifestyle interventions are effective for overweight individuals with prediabetes. To illustrate the potential clinical and economic benefits of treating prediabetes with lifestyle intervention to prevent or delay onset of type 2 diabetes and sequelae. This 2014 analysis used a Markov model to simulate disease onset, medical expenditures, economic outcomes, mortality, and quality of life for a nationally representative sample with prediabetes from the 2003-2010 National Health and Nutrition Examination Survey. Modeled scenarios used 10-year follow-up results from the lifestyle arm of the Diabetes Prevention Program and Outcomes Study versus simulated natural history of disease. Over 10 years, estimated average cumulative gross economic benefits of treating patients who met diabetes screening criteria recommended by the ADA ($26,800) or USPSTF ($24,700) exceeded average benefits from treating the entire prediabetes population ($17,800). Estimated cumulative, gross medical savings for these three populations averaged $10,400, $11,200, and $6,300, respectively. Published estimates suggest that opportunistic screening for prediabetes is inexpensive, and lifestyle intervention similar to the Diabetes Prevention Program can be achieved for ≤$2,300 over 10 years. Lifestyle intervention among people with prediabetes produces long-term societal benefits that exceed anticipated intervention costs, especially among prediabetes patients that meet the ADA and USPSTF screening guidelines.

2013-01-01

Tocopherols (vitamin E) and tea polyphenols have been reported to have cancer preventive activities. Large-scale human trials with high doses of alpha-tocopherol, however, have produced disappointing results. This review presents data showing that γ- and δ-tocopherols inhibit colon, lung, mammary and prostate carcinogenesis in animal models, whereas α-tocopherol is ineffective in animal and human studies. Possible mechanisms of action are discussed. A broad cancer preventive activity of green tea polyphenols has been demonstrated in animal models, and many mechanisms have been proposed. The cancer preventive activity of green tea in humans, however, has not been conclusively demonstrated and remains to be further investigated. PMID:23403075

The emerging field of cancer prevention through chemoprevention agents and cancer vaccines offers significant promise for reducing suffering and death from cancer. However, that promise may not be kept unless major barriers to progress are lowered or eliminated. Among the most significant barriers are the relatively small investment from government and industry in research and development of cancer preventive agents; a predominant emphasis of translational cancer research on therapeutic interventions for metastatic or advanced cancer; complexities of prevention trial design; a relatively uncharted Food and Drug Administration (FDA) approval process for preventive agents; insufficient public and patient understanding of the importance and potential for cancer preventive measures, with consequent unpredictable public and patient willingness to take preventive agents; an uncertain reimbursement from payors; and limitations in patent law, liability protection, and data package exclusivity that undermine the opportunity for recouping investment. Viewed individually or collectively, each of these barriers serves as a substantial deterrent to intellectual and financial investment by all sectors of the cancer community. In an effort to ultimately overcome these barriers, a Cancer Prevention Research Summit was assembled June 12-13, 2006 in Bethesda, Maryland, organized by C-Change with support from the AACR. The Summit brought together some 120 leaders from private, public, and not-for-profit entities, including cancer researchers and clinicians; federal health officials; regulatory agency representatives; pharmaceutical, biotech, and food industry leaders; patent attorneys; economists; public and private provider group executives; and advocates. Participants engaged in a detailed process to more carefully define the major barriers, identify potential solutions, and formulate initial priorities and recommendations for action.

2011-01-01

Cancer-induced cachexia remains a significant cause of morbidity and mortality in cancer treatment. Cancer research and development continues at an aggressive pace and yet a degree of cancer-induced cachexia is experienced by up to 80% of advanced stage cancer patients. Unfortunately, there are no established treatment regimens for this condition. Weight loss and fatigue consistently appear in patient oncologic histories and progress notes. However, few oncologists fully understand the pathologic mechanisms causing cachexia resulting in well-meaning advice to increase caloric intake with minimal results. Our goal is to describe the pathologic basis of cancer-induced cachexia and to detail accompanying metabolic derangements. Understanding the causes of cachexia sheds light on the subsequent need for multi-modality therapy including clinical intervention with specialized nutrition support, drug therapy, lifestyle and diet changes. In addition to nutrition support modalities, practicing oncologists may prescribe medical therapies designed to increase body weight and lean body mass, including megestrol acetate, tetrahydrocannibinol, oxandrolone, and non-steroidal anti-inflammatory drugs. A variety of experimental therapies are also being investigated for cancer-induced cachexia including tumor necrosis factor-alpha inhibitors and ghrelin infusions. We review the available data to support nutrition-oriented interventions in cancer-induced cachexia, including omega-3 fatty acids, amino-acid loading/protein supplementation, parenteral and enteral nutrition support, and food-derived compounds such as curcumin, reservatrol, and pomegranate.

2013-01-01

The Selenium and Vitamin E Cancer Prevention Trial (SELECT) was conducted to assess the efficacy of selenium and vitamin E alone, and in combination, on the incidence of prostate cancer. This randomized, double-blind, placebo-controlled, 2 × 2 factorial design clinical trial found that neither selenium nor vitamin E reduced the incidence of prostate cancer after seven years and that vitamin E was associated with a 17% increased risk of prostate cancer compared to placebo. The null result was surprising given the strong preclinical and clinical evidence suggesting chemopreventive activity of selenium. Potential explanations for the null findings include the agent formulation and dose, the characteristics of the cohort, and the study design. It is likely that only specific subpopulations may benefit from selenium supplementation; therefore, future studies should consider the baseline selenium status of the participants, age of the cohort, and genotype of specific selenoproteins, among other characteristics, in order to determine the activity of selenium in cancer prevention.

In France, women carrying BRCA1/2 mutation, at an identified high risk of breast cancer are recommended to undergo breast MRI screening. That screening does not however prevent the risk of developing a breast cancer. The only alternative to breast cancer screening available in France is surgical prevention by prophylactic mastectomy. An interesting option for women who wish to reduce their breast cancer risk, but are unready for prophylactic mastectomy is a preventive hormonal treatment by aromatase inhibitors, or selective estrogens receptor modulators (SERMs). Reliable clinical trials show the efficiency of tamoxifen, raloxifen, exemestane, and anastrozole especially, in reducing breast cancer incidence by 33%, 34%, 65% and 53% respectively. This article tries to sum up the main published trials of breast cancer prevention with hormonal treatment, and presents the latest American and English clinical guidelines concerning hormonal prevention for women at high risk of breast cancer, and starts thinking about the possibilities of hormonoprevention, especially among women carrying a BRCA1/2 mutation in France.

Aromatase inhibitors for prevention of breast cancer in postmenopausal women: a narrative review.

Science.gov (United States)

Behan, Lucy Ann; Amir, Eitan; Casper, Robert F

2015-03-01

The increasing incidence of breast cancer (BC) worldwide has resulted in widespread interest in primary prevention therapies. A number of large randomized trials have shown that selective estrogen receptor modulators can reduce the relative risk for BC by 30% to 40% in high-risk women. In early-stage BC, aromatase inhibitors (AIs) showed a 35% relative reduction in the risk of contralateral BCs compared with tamoxifen. In this narrative review, we discuss the role of AIs in the primary prevention of BC and novel research on combination hormone therapy-medical therapy for the primary prevention of BC. Using PubMed/Medline, we comprehensively searched for studies of BC primary prevention using AIs, including studies of novel methods of prevention using combination hormone therapy-BC prevention. Two large multicenter, prospective, randomized, placebo-controlled trials have evaluated AIs--anastrozole (International Breast Cancer Intervention Study II) and exemestane (Mammary Prevention 3)--for BC risk reduction in women at increased risk for BC, which we summarize. We identified five studies (three completed and two ongoing) of combination AI-hormone therapy that are undergoing investigation for BC risk reduction. AIs are effective at BC risk reduction, although long-term follow-up data are required to assess whether this risk reduction will result in reduced mortality. Combination hormone therapy-AI for BC risk reduction is experimental and warrants further investigation.

Interventions for preventing obesity in children

Full Text Available BACKGROUND: Prevention of childhood obesity is an international public health priority given the significant impact of obesity on acute and chronic diseases, general health, development and well-being. The international evidence base for strategies that governments, communities and families can implement to prevent obesity, and promote health, has been accumulating but remains unclear. OBJECTIVE: This review primarily aims to update the previous Cochrane review of childhood obesity prevention research and determine the effectiveness of evaluated interventions intended to prevent obesity in children, assessed by change in Body Mass Index (BMI. Secondary aims were to examine the characteristics of the programs and strategies to answer the questions "What works for whom, why and for what cost?" METHODS: Search methods: The searches were re-run in CENTRAL, MEDLINE, EMBASE, PsychINFO and CINAHL in March 2010 and searched relevant websites. Non-English language papers were included and experts were contacted. Selection criteria: The review includes data from childhood obesity prevention studies that used a controlled study design (with or without randomisation. Studies were included if they evaluated interventions, policies or programs in place for twelve weeks or more. If studies were randomized at a cluster level, six clusters were required. Data collection and analysis: Two review authors independently extracted data and assessed the risk of bias of included studies. Data was extracted on intervention implementation, cost, equity and outcomes. Outcome measures were grouped according to whether they measured adiposity, physical activity (PA-related behaviours or diet-related behaviours. Adverse outcomes were recorded. A meta-analysis was conducted using available BMI or standardized BMI (zBMI score data with subgroup analysis by age group (0-5, 6-12, 13-18 years, corresponding to stages of developmental and childhood settings.

The influence of health disparities on targeting cancer prevention efforts.

Zonderman, Alan B; Ejiogu, Ngozi; Norbeck, Jennifer; Evans, Michele K

2014-03-01

Despite the advances in cancer medicine and the resultant 20% decline in cancer death rates for Americans since 1991, there remain distinct cancer health disparities among African Americans, Hispanics, Native Americans, and the those living in poverty. Minorities and the poor continue to bear the disproportionate burden of cancer, especially in terms of stage at diagnosis, incidence, and mortality. Cancer health disparities are persistent reminders that state-of-the-art cancer prevention, diagnosis, and treatment are not equally effective for and accessible to all Americans. The cancer prevention model must take into account the phenotype of accelerated aging associated with health disparities as well as the important interplay of biological and sociocultural factors that lead to disparate health outcomes. The building blocks of this prevention model will include interdisciplinary prevention modalities that encourage partnerships across medical and nonmedical entities, community-based participatory research, development of ethnically and racially diverse research cohorts, and full actualization of the prevention benefits outlined in the 2010 Patient Protection and Affordable Care Act. However, the most essential facet should be a thoughtful integration of cancer prevention and screening into prevention, screening, and disease management activities for hypertension and diabetes mellitus because these chronic medical illnesses have a substantial prevalence in populations at risk for cancer disparities and cause considerable comorbidity and likely complicate effective treatment and contribute to disproportionate cancer death rates.

Brief interventions for smoking cessation and alcohol moderation may contribute considerably to the prevention of cancer among populations at risk, such as cancer survivors, in addition to improving their general wellbeing. There is accumulating evidence for the effectiveness of internet-based brief health behaviour interventions. The objective of this study is to assess the effectiveness, patient-level cost-effectiveness and cost-utility of two new online theory-based self-help interventions among adult cancer survivors in the Netherlands. One of the interventions focuses on alcohol moderation, the other on smoking cessation. Both interventions are tailored to cancer survivors. Effectiveness will be assessed in two separate, nearly identical 2-armed RCTs: alcohol moderation (AM RCT) and smoking cessation (SC RCT). Participants are randomly allocated to either the intervention groups or the control groups. In the intervention groups, participants have access to one of the newly developed interventions. In the control groups, participants receive an online static information brochure on alcohol (AM RCT) or smoking (SC RCT). Main study outcome parameters are the number of drinks post-randomisation (AM RCT) and tobacco abstinence (SC RCT). In addition, cost-data and possible effect moderators and mediators will be assessed. Both treatments are internet-based minimally guided self-help interventions: MyCourse - Moderate Drinking (in Dutch: MijnKoers - Minderen met Drinken) and MyCourse - Quit Smoking (MijnKoers - Stoppen met Roken). They are based on cognitive behaviour therapy (CBT), motivational interviewing (MI) and acceptance and commitment therapy (ACT). Both interventions are optimized in collaboration with the target population of cancer survivors in focus groups and interviews, and in collaboration with several experts on eHealth, smoking cessation, alcohol misuse and cancer survivorship. The present study will add to scientific knowledge on the (cost

Objective: To investigate the interventional therapy and its curative effect for progressing stage gastric cancer. Methods: two hundred and twelve patients with progressing stage gastric cancer were treated with arterial perfusion and arterial embolization. Gastric cardia cancer was treated through the left gastric artery and the left inferior phrenic artery or splenic artery. Cancers of lesser and greater gastric curvature was treated either through the left and right gastric arteries or common hepatic artery or through gastroduodenal artery, right gastroomental artery or splenic artery. Gastric antrum cancers were perfused through gastroduodenal artery or after the middle segmental embolization of right gastroomental artery. Results: One hundred and ninety three cases undergone interventional management were followed up. The CR + PR of gastric cardia cancer was 53.13%; gastric body cancer 44.44%; gastric antrum cancer 10%; recurrent cancer and remnant gastric cancer 0. There was no significant difference in outcome between gastric cardia cancer and gastric body cancer (P>0.05) but significant differences were shown both between gastric cardia cancer and gastric antrum cancer, and between gastric body cancer and gastric antrum cancer (P<0.05), with 1 year and 2 years survival rates of 81% and 56% respectively. Conclusion: The interventional therapeutic effect of progressing stage gastric cancers is different due to the different sites of the lesions in the gastric tissue. The curative effect of gastric cardia cancer and gastric body cancer is better than that of gastric antrum cancer, recurrent cancer and remnant gastric cancer. (authors)

Physical Activity and Nutrition in Primary and Tertiary Prevention of Colorectal Cancer.

Lifestyle factors play a pivotal role in the primary and tertiary prevention of colorectal cancer. The purpose of this review article is to summarize data concerning the effect of the lifestyle factors physical activity (PA) and nutrition in primary and, more importantly, tertiary prevention of colorectal cancer (CRC). Focusing on the influence of lifestyle factors on prognosis und quality of life (QOL), a comprehensive literature search of clinical studies published mainly in the years 2000 until 2015 was performed and the current knowledge based on these clinical studies reviewed. Besides avoiding risk factors (such as smoking and overindulgence in alcohol), healthy weight, regular and moderate PA as well as a diet which contains fruit, vegetables, poultry, and fish (so-called 'Mediterranean' diet) may reduce the risk of the disease significantly. Patients already diagnosed with CRC can also actively improve the prognosis of CRC and QOL by changing their lifestyle. Patients commencing moderate exercise and modifying their eating habits in terms of a 'Mediterranean' diet can reduce cancer-specific and overall mortality by up to 40% and significantly increase their quality of life already during chemotherapy. Therefore, moderate physical exercise, calorie restriction, and a Mediterranean dietary pattern for patients with CRC should be recommended by physicians treating these patients. In fact, the World Cancer Research Fund/American Institute for Cancer Research (AICR/WCRF) systematic literature review from 2007 shows that the lifestyle changes recommended after diagnosis are the same for primary prevention of this disease. Lifestyle changes such as moderate PA and a Mediterranean diet significantly improve the QOL as well as the prognosis of patients suffering from colorectal disease. However, the effect of lifestyle changes is mostly based on observational studies, while only few studies are prospective and none are randomized. Therefore, these observational

Evidence-based obesity prevention in childhood and adolescence: critique of recent etiological studies, preventive interventions, and policies.

Science.gov (United States)

Reilly, John J

2012-07-01

Prevention of obesity in childhood and adolescence remains a worthwhile and realistic goal, but preventive efforts have been beset by a number of problems, which are the subject of this review. The review draws on recent systematic reviews and evidence appraisals and has a United Kingdom (UK) perspective because there is a rich evidence base in the United Kingdom that may be helpful to obesity prevention researchers elsewhere. Recent evidence of a leveling off in child and adolescent obesity prevalence in some Western nations should not encourage the belief that the obesity prevention problem has been solved, although a better understanding of recent secular trends might be helpful for prevention strategy in future. An adequate body of evidence provides behavioral targets of preventive interventions, and there are frameworks for prioritizing these targets logically and models for translating them into generalizable interventions with a wide reach (e.g., school-based prevention interventions such as Planet Health). An improved understanding of the "energy gap" that children and adolescents experience would be helpful to the design of preventive interventions and to their tailoring to particular groups. In the United Kingdom, some recent etiological evidence has been taken as indicative of the need for paradigm shifts in obesity prevention, but this evidence from single studies has not been replicated, and paradigm shifts probably occur only rarely. Ensuring that the evidence base on etiology and prevention influences policy effectively remains one of the greatest challenges for childhood obesity researchers.

People with advanced cancer face difficulties with their everyday activities at home that may reduce their health-related quality of life. To address these difficulties, we developed the 'Cancer Home-Life Intervention'. To evaluate the efficacy of the 'Cancer Home Life-Intervention' compared with usual care with regard to patients' performance of, and participation in, everyday activities, and their health-related quality of life. A randomised controlled trial ( ClinicalTrials.gov NCT02356627). The 'Cancer Home-Life Intervention' is a brief, tailored, occupational therapy-based and adaptive programme for people with advanced cancer targeting the performance of their prioritised everyday activities. Home-living adults diagnosed with advanced cancer experiencing functional limitations were recruited from two Danish hospitals. They were assessed at baseline, and at 6 and 12 weeks of follow-up. The primary outcome was activities of daily living motor ability. Secondary outcomes were activities of daily living process ability, difficulty performing prioritised everyday activities, participation restrictions and health-related quality of life. A total of 242 participants were randomised either to the intervention group ( n = 121) or the control group ( n = 121). No effect was found on the primary outcome (between-group mean change: -0.04 logits (95% confidence interval: -0.23 to 0.15); p = 0.69). Nor was any effect on the secondary outcomes observed. In most cases, the 'Cancer Home-Life Intervention' was delivered through only one home visit and one follow-up telephone contact, which not was effective in maintaining or improving participants' everyday activities and health-related quality of life. Future research should pay even more attention to intervention development and feasibility testing.

Background New screening and vaccination technologies will provide women with more options for cervical cancer prevention. Because the risk of cervical cancer diminishes with effective routine screening, women may wish to consider additional attributes, such as the likelihood of false-positive results and diagnostic procedures for mild abnormalities likely to resolve without intervention in their screening choices. Methods We used an empirically calibrated simulation model of cervical cancer in the United States to assess the benefits and potential risks associated with prevention strategies differing by primary screening test, triage test for abnormal results (cytologic testing, human papillomavirus [HPV] DNA test), and screening frequency. Outcomes included colposcopy referrals, cervical intraepithelial neoplasia (CIN) types 1 and 2 or 3, lifetime cancer risk, and quality-adjusted life expectancy. Results Across strategies, colposcopy referrals and diagnostic workups varied 3-fold, although diagnostic rates of CIN 2 or 3 were similar and 95% of positive screening test results were for mild abnormalities likely to resolve on their own. For a representative group of a thousand 20-year-old women undergoing triennial screening for 10 years, we expect 1038 colposcopy referrals (7 CIN 2 or 3 diagnoses) from combined cytologic and HPV DNA testing and fewer than 200 referrals (6–7 CIN 2 or 3 diagnoses) for strategies that use triage testing. Similarly, for a thousand 40-year-old women, combined cytologic and HPV DNA testing led to 489 referrals (9 CIN 2 or 3), whereas alternative strategies resulted in fewer than 150 referrals (7–8 CIN 2 or 3). Using cytologic testing followed by triage testing in younger women minimizes both diagnostic workups and positive HPV test results, whereas in older women diagnostic workups are minimized with HPV DNA testing followed by cytologic triage testing.

Both human papillomavirus (HPV) vaccination and screening/treatment are relatively simple and inexpensive to implement at all resource levels, and cervical cancer screening has been acknowledged as a "best buy" by the WHO. However, coverage with these interventions is low where they are needed most. Failure to launch or expand cervical cancer prevention programs is by and large due to the absence of dedicated funding, along with a lack of recognition of the urgent need to update policies that can hinder access to services. Clear and sustained communication, robust advocacy, and strategic partnerships are needed to inspire national governments and international bodies to action, including identifying and allocating sustainable program resources. There is significant momentum for expanding coverage of HPV vaccination and screening/preventive treatment in low-resource settings as evidenced by new global partnerships espousing this goal, and the participation of groups that previously had not focused on this critical health issue. © 2017 The Authors.

Breast cancer currently accounts for 14% of new cancers in women in developing countries. As urbanization accelerates and more Third World women adopt Western diets and reproductive patterns, this rate can be expected to increase. Researchers have accumulated a significant knowledge base of the risk factors associated with breast cancer. Early 1st menstruation, having a 1st fullterm pregnancy after age 30 years, and going through menopause after age 50 years are all believed to increase this risk. Although studies have failed to reveal any consistent association between oral contraceptive (OC) use and breast cancer, there is some evidence of an increased risk among women under age 45 years who started OC use early or used this contraceptive method for a long time. Obesity, and the diet prevalent in developed countries--high in fat, low in fiber, and high in calories--are other risk factors for breast cancer. Several studies have shown that women who moved to the US from countries such as Japan with low breast cancer rates approached the risk levels of US women within 1 generation as a result of the adoption of a Western lifestyle. Of particular concern in developing countries is the fact that most breast cancers go undiagnosed or are not detected early enough to allow for effective treatment, if treatment is even available. Cultural taboos often prevent both women and physicians from examining the breasts for lumps. Both developed and developing countries must begin devoting more attention to the prevention of breast cancer. An important preventive step is for mothers to breastfeed their infants for at least 1 years.

The goal of this review is to raise awareness about refeeding syndrome (RFS) and to give a comprehensive presentation of recent guidelines and latest scientific data about nutritional management among head and neck cancer (HNC) patients while focusing on RFS prevention. A review of literature for nutritional assessment and RFS management was conducted. Electronic searches of Medline, Cochrane, PubMed and Embase databases for articles published in peer-reviewed journals were conducted from February to September 2017 using the keywords: "nutrition assessment", "head and neck cancer", "refeeding syndrome" and "guidelines". Articles, reviews, book references as well as national and international guidelines in English and French were included. The prevalence of malnutrition is high in HNC patients and a large number of them will need artificial nutritional support or refeeding intervention. RFS is characterized by fluid and electrolyte imbalance associated with clinical manifestations induced by rapid refeeding after a period of malnutrition or starvation. Regarding risk factors for malnutrition and RFS, HNC patients are particularly vulnerable. However, RFS remains unrecognized among head and neck surgeons and medical teams. Practical data are summarized to help organizing nutritional assessment and refeeding interventions. It also summarizes preventive measures to reduce RFS incidence and morbidity in HNC population. Nutritional assessment and early refeeding interventions are crucial for HNC patients care. As prevention is the key for RFS management, early identification of patients with high risks is crucial and successful nutritional management requires a multidisciplinary approach.

Colorectal cancer (CRC) is the third most common cancer diagnosis and the second and third leading cause of cancer mortality in men and women, respectively. However, the majority of CRC cases are the result of sporadic tumorigenesis via the adenoma–carcinoma sequence. This process can take up to 20 years, suggesting an important window of opportunity exists for prevention such as switching toward healthier dietary patterns. The Mediterranean diet (MD) is a dietary pattern associated with various health benefits including protection against cardiovascular disease, diabetes, obesity, and various cancers. In this article, we review publications available in the PubMed database within the last 10 years that report on the impact of a MD eating pattern on prevention of CRC. To assist the reader with interpretation of the results and discussion, we first introduce indexes and scoring systems commonly used to experimentally determine adherence to a MD, followed by a brief introduction of the influence of the MD pattern on inflammatory bowel disease, which predisposes to CRC. Finally, we discuss key biological mechanisms through which specific bioactive food components commonly present in the MD are proposed to prevent or delay the development of CRC. We close with a discussion of future research frontiers in CRC prevention with particular reference to the role of epigenetic mechanisms and microbiome related to the MD eating pattern.

Spices have been widely used as food flavorings and folk medicines for thousands of years. Numerous studies have documented the antioxidant, anti-inflammatory and immunomodulatory effects of spices, which might be related to prevention and treatment of several cancers, including lung, liver, breast, stomach, colorectum, cervix, and prostate cancers. Several spices are potential sources for prevention and treatment of cancers, such as Curcuma longa (tumeric), Nigella sativa (black cumin), Zingiber officinale (ginger), Allium sativum (garlic), Crocus sativus (saffron), Piper nigrum (black pepper) and Capsicum annum (chili pepper), which contained several important bioactive compounds, such as curcumin, thymoquinone, piperine and capsaicin. The main mechanisms of action include inducing apoptosis, inhibiting proliferation, migration and invasion of tumors, and sensitizing tumors to radiotherapy and chemotherapy. This review summarized recent studies on some spices for prevention and treatment of cancers, and special attention was paid to bioactive components and mechanisms of action.

To conduct a meta-analysis of computer technology-based HIV prevention behavioral interventions aimed at increasing condom use among a variety of at-risk populations. Systematic review and meta-analysis of existing published and unpublished studies testing computer-based interventions. Meta-analytic techniques were used to compute and aggregate effect sizes for 12 randomized controlled trials that met inclusion criteria. Variables that had the potential to moderate intervention efficacy were also tested. The overall mean weighted effect size for condom use was d = 0.259 (95% confidence interval = 0.201, 0.317; Z = 8.74, P partners, and incident sexually transmitted diseases. In addition, interventions were significantly more efficacious when they were directed at men or women (versus mixed sex groups), utilized individualized tailoring, used a Stages of Change model, and had more intervention sessions. Computer technology-based HIV prevention interventions have similar efficacy to more traditional human-delivered interventions. Given their low cost to deliver, ability to customize intervention content, and flexible dissemination channels, they hold much promise for the future of HIV prevention.

During the last two decades, there have been spiritual/religious interventions in cancer patients to prevent or treat a range of physical problems, including managing chronic pain, coping with the disease, boosting hope and mental health. Although societies are of different faiths and belief systems, what they all share is spirituality. Upon this we put forward the hypothesis of changes in gene receptor expressions as a result of spiritual intervention for the first time in the world. In this study, the spiritual intervention was conducted on 57 volunteer females with early breast cancer involvement. Blood samples were collected prior to and after the spiritual intervention to analyze the changes in dopamine gene receptor expressions as the main site of effect. In order to administer the spiritual intervention backed by Quran, Islam and international standards, issues, with emphasis on peace, human growth and perfection, accepting God as an eternal source of power and kindness to build trust and reduce stress, were selected. They included prayer, patience, reliance, self-sacrifice and forgiveness, altruism and kindness, remission and repentance, thankfulness, zikr (mantra), meditation, and death concept. Obtained results from peripheral blood mononuclear cell samples analyzed by real time-PCR showed significant reduction in dopamine gene receptor (DRD1-5) expressions in comparison with those of pre-test scores and the control group. Spiritual intervention based on Islamic principals can bring back mental health, increase hope and quality of life and eventually change dopamine gene receptor expressions resulting in reduction of cell proliferation, thus better prevention and management in breast cancer patients compared to other forms of treatment.

Several medical management approaches have been shown to be effective in preventing breast cancer and detecting it early among women at elevated risk: 1) prophylactic mastectomy; 2) prophylactic oophorectomy; 3) chemoprevention; and 4) enhanced screening routines. To varying extents, however, these approaches are substantially underused relative to clinical practice recommendations. This article reviews the existing research on the uptake of these prevention approaches, the characteristics of women who are likely to use various methods, and the decision-making processes that underlie the differing choices of women. It also highlights important areas for future research, detailing the types of studies that are particularly needed in four key areas: documenting women's perspectives on their own perceptions of risk and prevention decisions; explicit comparisons of available prevention pathways and their likely health effects; the psychological, interpersonal, and social processes of prevention decision making; and the dynamics of subgroup variation. Ultimately, this research could support the development of interventions that more fully empower women to make informed and values-consistent decisions, and to move towards favorable health outcomes.

The Prevention of Hereditary Breast and Ovarian Cancer: A Personal View

Directory of Open Access Journals (Sweden)

Narod Steven

2004-02-01

Full Text Available Abstract Options for the prevention of hereditary breast and ovarian cancer include screening, preventive surgery and chemoprevention. Screening studies with magnetic resonance imaging of the breast are promising but the technology is not widespread and MRI is unlikely to be available as a screening tool in the near future. Prophylactic oophorectomy and mastectomy are effective preventive measures and are gaining in acceptance by patients and physicians. Preventive mastectomy is effective against both primary and contralateral breast cancer. Oophorectomy prevents ovarian cancer, and if done prior to menopause, will prevent breast cancer as well. Tamoxifen has been shown to prevent contralateral breast cancers in BRCA1 and BRCA2 carriers but is not widely accepted as a means of primary prevention. Oral contraceptives and tubal ligation will reduce the risk of hereditary ovarian cancer and should be considered in women who wish to retain ovarian function.

Protein restriction without malnutrition is currently an effective nutritional intervention known to prevent diseases and promote health span from yeast to human. Recently, low protein diets are reported to be associated with lowered cancer incidence and mortality risk of cancers in human. In murine models, protein restriction inhibits tumor growth via mTOR signaling pathway. IGF-1, amino acid metabolic programing, FGF21, and autophagy may also serve as potential mechanisms of protein restriction mediated cancer prevention. Together, dietary intervention aimed at reducing protein intake can be beneficial and has the potential to be widely adopted and effective in preventing and treating cancers.

Full Text Available Breast cancer survivors are at risk of developing a second primary cancer. Colorectal cancer (CRC is one of the leading second primary cancers, and it is often preventable. We developed a multi-component educational tool to inform and encourage women breast cancer survivors to engage in CRC screening. To assess the strengths and weakness of the tool and to improve the relevancy to the target audience, we convened four focus groups of women breast cancer survivors in Missouri. We also assessed the potential impact of the tool on the knowledge, attitudes, and beliefs regarding CRC and collected information on the barriers to CRC screening through pre- and post-focus groups’ questionnaires. A total of 43 women breast cancer survivors participated and provided very valuable suggestions on design and content to update the tool. Through the process and comparing pre- and post-focus group assessments, a significantly higher proportion of breast cancer survivors strongly agreed or agreed that CRC is preventable (78.6% vs. 96.9%, p = 0.02 and became aware that they were at a slightly increased risk for CRC (18.6% vs. 51.7%, p = 0.003. The most cited barrier was the complexity of preparation for colonoscopy.

Full Text Available Pancreatic ductal adenocarcinoma (PDA accounts for 95% of all pancreatic cancers. About 230,000 PDA cases are diagnosed worldwide each year. PDA has the lowest five-year survival rate as compared to others cancers. PDA in Poland is the fifth leading cause of death after lung, stomach, colon and breast cancer. In our paper we have analysed the newest epidemiological research, some of it controversial, to establish the best practical solution for pancreatic cancer prevention in the healthy population as well as treatment for patients already diagnosed with pancreatic cancer. We found that PDA occurs quite frequently but is usually diagnosed too late, at its advanced stage. Screening for PDA is not very well defined except in subgroups of high-risk individuals with genetic disorders or with chronic pancreatitis. We present convincing, probable, and suggestive risk factors associated with pancreatic cancer, many of which are modifiable and should be introduced and implemented in our society.

Life style prevention of cancer recurrence: the yin and the yang.

Science.gov (United States)

Berrino, Franco

2014-01-01

There is increasing evidence that lifestyle after the diagnosis of cancer may affect prognosis. Several studies have shown that a Western dietary pattern, obesity, weight gain, a sedentary lifestyle, metabolic syndrome, high serum levels of insulin, growth factors, and inflammatory cytokines after the diagnosis of cancer are associated with an increased incidence of recurrences. Most studies have been on breast and colon cancer. However, in the clinical management of cancer, little attention is presently paid to improving lifestyle and controlling body weight. Lifestyle intervention trials are needed to corroborate or confute the observational results on cancer recurrences, but, even now, there is no contraindication to promoting moderate physical exercise, moderate calorie restriction (CR), and a Mediterranean dietary pattern. In fact, the AICR/WCRF 2007 systematic literature review recommends cancer patients to adopt the lifestyle recommended for the prevention of cancer. Interestingly, the evidence-based AICR/WCRF recommendations coincide with traditional rules, based on far Eastern philosophy, of avoiding extremely yin food, such as sugared beverages and calorie-dense foods, and extremely yang food, such as processed meat, and relying on the equilibrium of slightly yang food, such as whole-grain unprocessed cereals, eaten with slightly yin food, such as legumes and vegetables.

Physician Training in Cancer Prevention and Control: A Population Health Imperative.

Science.gov (United States)

Moore, Miranda A; Goodman, Richard A

2018-03-01

Cancer is the second leading cause of morbidity and mortality in the U.S. Although reducing the number of new cancer cases is a national health goal, the continuing growth of the older adult population ensures that the burden of cancer will increase. Despite documentation of the shortage of oncologists to meet the growing need, relatively limited attention has been focused on increasing the physician workforce trained in the prevention and control of cancer. The existing physician workforce with such specialized training in cancer prevention and control is small, aging, increasing at a low rate, and likely to decrease because of an imbalance between retiring physicians and new entrants. This commentary addresses the imperative for increasing the number of physicians trained in preventive medicine with a specialization in cancer prevention and control by first providing a brief overview of U.S. cancer morbidity and mortality, then describing the status of, and trends in, physician training in cancer prevention and control, and concluding by suggesting opportunities for bolstering physician training in cancer prevention and control.

Psychosocial intervention effects on adaptation, disease course and biobehavioral processes in cancer.

Science.gov (United States)

Antoni, Michael H

2013-03-01

A diagnosis of cancer and subsequent treatments place demands on psychological adaptation. Behavioral research suggests the importance of cognitive, behavioral, and social factors in facilitating adaptation during active treatment and throughout cancer survivorship, which forms the rationale for the use of many psychosocial interventions in cancer patients. This cancer experience may also affect physiological adaptation systems (e.g., neuroendocrine) in parallel with psychological adaptation changes (negative affect). Changes in adaptation may alter tumor growth-promoting processes (increased angiogenesis, migration and invasion, and inflammation) and tumor defense processes (decreased cellular immunity) relevant for cancer progression and the quality of life of cancer patients. Some evidence suggests that psychosocial intervention can improve psychological and physiological adaptation indicators in cancer patients. However, less is known about whether these interventions can influence tumor activity and tumor growth-promoting processes and whether changes in these processes could explain the psychosocial intervention effects on recurrence and survival documented to date. Documenting that psychosocial interventions can modulate molecular activities (e.g., transcriptional indicators of cell signaling) that govern tumor promoting and tumor defense processes on the one hand, and clinical disease course on the other is a key challenge for biobehavioral oncology research. This mini-review will summarize current knowledge on psychological and physiological adaptation processes affected throughout the stress of the cancer experience, and the effects of psychosocial interventions on psychological adaptation, cancer disease progression, and changes in stress-related biobehavioral processes that may mediate intervention effects on clinical cancer outcomes. Very recent intervention work in breast cancer will be used to illuminate emerging trends in molecular probes of

Full Text Available Abstract Background UK NHS Stop Smoking Services provide cost effective smoking cessation interventions but, as yet, there has been no assessment of their provision of relapse prevention interventions. Methods Electronic questionnaire survey of 185 UK Stop Smoking Services Managers. Results Ninety six Stop Smoking Service managers returned completed questionnaires (52% response rate. Of these, 58.3% (n = 56 ran NHS Stop Smoking Services which provided relapse prevention interventions for clients with the most commonly provided interventions being behavioural support: telephone (77%, group (73%, and individual (54%. Just under half (48%, n = 27 offered nicotine replacement therapy (NRT, 21.4% (n = 12 bupropion; 19.6% (n = 11 varenicline. Over 80% of those providing relapse prevention interventions do so for over six months. Nearly two thirds of all respondents thought it was likely that they would either continue to provide or commence provision of relapse prevention interventions in their services. Of the remaining respondents, 66.7% (n = 22 believed that the government focus on four-week quit rates, and 42.9% (14 services believed that inadequate funding for provision of relapse prevention interventions, were major barriers to introducing these interventions into routine care. Conclusions Just over half of UK managers of NHS Stop Smoking Services who responded to the questionnaire reported that, in their services, relapse prevention interventions were currently provided for clients, despite, at that time, there being a weak evidence base for their effectiveness. The most commonly provided relapse prevention interventions were those for which there was least evidence. If these interventions are found to be effective, barriers would need to be removed before they would become part of routine care.

Interventions addressing general parenting to prevent or treat childhood obesity.

2011-06-01

Observational studies increasingly emphasize the impact of general parenting on the development of childhood overweight and obesity. The aim of the current literature review was to provide an overview of interventions addressing general parenting in order to prevent or treat childhood obesity. Electronic literature databases were systematically searched for relevant studies. Seven studies were eligible for inclusion. The studies described four different general parenting programs, which were supplemented with lifestyle components (i.e., physical activity and nutrition). All studies showed significant small to moderate intervention effects on at least one weight-related outcome measure. The current review shows that despite the emerging observational evidence for the role of parenting in children's weight-related outcomes, few interventions have been developed that address general parenting in the prevention of childhood obesity. These interventions provide evidence that the promotion of authoritative parenting is an effective strategy for the prevention and management of childhood obesity.

Improving surgical site infection prevention practices through a multifaceted educational intervention.

Owens, P

2015-03-01

As part of the National Clinical Programme on healthcare-associated infection prevention, a Royal College of Surgeons in Ireland (RCSI) and Royal College of Physicians of Ireland (RCPI) working group developed a quality improvement tool for prevention of surgical site infection (SS). We aimed to validate the effectiveness of an educational campaign, which utilises this quality improvement tool to prevent SSI in a tertiary hospital. Prior to the SSI educational campaign, surgical patients were prospectively audited and details of antibiotic administration recorded. Prophylactic antibiotic administration recommendations were delivered via poster and educational presentations. Post-intervention, the audit was repeated. 50 patients were audited pre-intervention, 45 post-intervention. Post-intervention, prophylaxis within 60 minutes prior to incision increased from 54% to 68% (p = 0.266). Appropriate postoperative prescribing improved from 71% to 92% (p = 0.075). A multifaceted educational program may be effective in changing SSI prevention practices.

Lorenzo Tomatis and primary prevention of environmental cancer

Full Text Available Abstract The leading 20th century proponent for primary prevention of environmental cancer was Dr. Lorenzo Tomatis, the former Director of the International Agency for Research on Cancer and founder of the IARC Monographs program. This paper is dedicated to the memory of Dr. Tomatis – eminent scientist, scholar, teacher, humanitarian, and public health champion - and includes many perspectives that he promoted throughout his career, with original quotations from some of his scientific writings on primary prevention of environmental cancer. Any attempt by us to simply summarize his views would only detract from the power and logic of his language. “Cancer still remains a mainly lethal disease. Primary prevention remains the most relevant approach to reduce mortality through a reduction in incidence”1.

[Scientific Evidence on Preventive Interventions in Childhood Obesity].

Alba-Martín, Raquel

The increasing prevalence of obesity or overweight at all ages, their associated morbidity and mortality associated, and the increased perception of the problem by the society have generated several hypotheses in response to the scientific and the international community. Investigate the preventive interventions in childhood obesity so far. Integrative review during the study period from April 2013 to November 2014. The MEDLINE international database was used, including PubMed, the Cochrane Library (Issue 4 2002), the national database Isooc (CSIC) national database, as well as the Internet. The review included health articles published in Spanish and English between 1990 and 2014 that focused on or included education, prevention, diagnostic, and treatment of obesity interventions. Of the 726 articles identified, 34 of most relevant (peer reviewed) were selected. It was noted that there is limited generisable evidence on interventions that could be implemented in Primary Care or referral services available, although numerous studies suggest that improvements in the overweight are possible. Despite the abundant literature and that many institutions place childhood obesity as one of the priorities of Public Health, we face the paradox that the evidence on cost-effectiveness of prevention interventions is sparse. Knowing these gaps in knowledge should lead to filling them with rigorous and well-designed studies. Copyright © 2016 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

2017-09-23

The high prevalence of prediabetes and success of the diabetes prevention program (DPP) has led to increasing efforts to provide readily accessible, cost-effective DPP interventions to the general public. Technology-assisted DPP interventions are of particular interest since they may be easier to widely distribute and sustain as compared to traditional in-person DPP. The purpose of this article is to provide an overview of currently available technology-assisted DPP interventions. This review focuses on studies that have examined the use of mobile phone text messaging, smartphone/web-based apps, and telehealth programs to help prevent or delay the onset of incident type 2 diabetes. While there is variability in the results of studies focused on technology-assisted DPP and weight loss interventions, there is evidence to suggest that these programs have been associated with clinically meaningful weight loss and can be cost-effective. Patients who are at risk for diabetes can be offered technology-assisted DPP and weight loss interventions to lower their risk of incident diabetes. Further research should determine what specific combination of intervention features would be most successful.

Priority Setting for Occupational Cancer Prevention

Full Text Available Background: Selecting priority occupational carcinogens is important for cancer prevention efforts; however, standardized selection methods are not available. The objective of this paper was to describe the methods used by CAREX Canada in 2015 to establish priorities for preventing occupational cancer, with a focus on exposure estimation and descriptive profiles. Methods: Four criteria were used in an expert assessment process to guide carcinogen prioritization: (1 the likelihood of presence and/or use in Canadian workplaces; (2 toxicity of the substance (strength of evidence for carcinogenicity and other health effects; (3 feasibility of producing a carcinogen profile and/or an occupational estimate; and (4 special interest from the public/scientific community. Carcinogens were ranked as high, medium or low priority based on specific conditions regarding these criteria, and stakeholder input was incorporated. Priorities were set separately for the creation of new carcinogen profiles and for new occupational exposure estimates. Results: Overall, 246 agents were reviewed for inclusion in the occupational priorities list. For carcinogen profile generation, 103 were prioritized (11 high, 33 medium, and 59 low priority, and 36 carcinogens were deemed priorities for occupational exposure estimation (13 high, 17 medium, and 6 low priority. Conclusion: Prioritizing and ranking occupational carcinogens is required for a variety of purposes, including research, resource allocation at different jurisdictional levels, calculations of occupational cancer burden, and planning of CAREX-type projects in different countries. This paper outlines how this process was achieved in Canada; this may provide a model for other countries and jurisdictions as a part of occupational cancer prevention efforts.

Functional breast cancer literacy was assessed among African-American women and measured at the domain level over time. We used the Kin Keeper(SM) Cancer Prevention Intervention to educate 161 African-American women on three domains of breast cancer literacy: (i) cancer awareness, (ii) knowledge of breast cancer screening modalities and (iii) cancer prevention and control. A breast cancer literacy assessment was administered pre- and post-educational intervention at two time points followed by another assessment 12 months after the second intervention. Generalized estimating equations were specified to predict the probability of correctly answering questions in each domain over time. Domain-level literacy differentials exist; at baseline, women had higher test scores in the breast cancer prevention and control domain than the cancer awareness domain (odds ratio = 1.67, 95% confidence interval 1.19-2.34). After Kin Keeper(SM) Cancer Prevention Intervention, African-American women consistently improved their breast cancer literacy in all domains over the five time stages (P < 0.001) though at different rates for each domain. Differences in domain-level breast cancer literacy highlight the importance of assessing literacy at the domain level. Interventions to improve African-American women's breast cancer literacy should focus on knowledge of breast cancer screening modalities and cancer awareness domains.

Chinese Anti-Cancer Association as a non-governmental organization undertakes systematic cancer prevention work in China

2015-01-01

Cancer has become the first leading cause of death in the world, particularly in low- and middle-income countries. Facing the increasing trend of cancer incidence and mortality, China issued and implemented “three-early (early prevention, early diagnosis and early treatment)” national cancer prevention plan. As the main body and dependence of social governance, non-governmental organizations (NGOs) take over the role of government in the field of cancer prevention and treatment. American Cancer Society (ACS) made a research on cancer NGOs and civil society in cancer control and found that cancer NGOs in developing countries mobilize civil society to work together and advocate governments in their countries to develop policies to address the growing cancer burden. Union for International Cancer Control (UICC), Cancer Council Australia (CCA), and Malaysian cancer NGOs are the representatives of cancer NGOs in promoting cancer control. Selecting Chinese Anti-Cancer Association (CACA) as an example in China, this article is to investigate how NGOs undertake systematic cancer prevention work in China. By conducting real case study, we found that, as a NGO, CACA plays a significant role in intensifying the leading role of government in cancer control, optimizing cancer outcomes, decreasing cancer incidence and mortality rates and improving public health.

Full Text Available Abstract Background Information on cost-effectiveness of the range of HIV prevention interventions is a useful contributor to decisions on the best use of resources to prevent HIV. We conducted this assessment for the state of Andhra Pradesh that has the highest HIV burden in India. Methods Based on data from a representative sample of 128 public-funded HIV prevention programs of 14 types in Andhra Pradesh, we have recently reported the number of HIV infections averted by each type of HIV prevention intervention and their cost. Using estimates of the age of onset of HIV infection, we used standard methods to calculate the cost per Disability Adjusted Life Year (DALY saved as a measure of cost-effectiveness of each type of HIV prevention intervention. Results The point estimates of the cost per DALY saved were less than US $50 for blood banks, men who have sex with men programmes, voluntary counselling and testing centres, prevention of parent to child transmission clinics, sexually transmitted infection clinics, and women sex worker programmes; between US $50 and 100 for truckers and migrant labourer programmes; more than US $100 and up to US $410 for composite, street children, condom promotion, prisoners and workplace programmes and mass media campaign for the general public. The uncertainty range around these estimates was very wide for several interventions, with the ratio of the high to the low estimates infinite for five interventions. Conclusions The point estimates for the cost per DALY saved from the averted HIV infections for all interventions was much lower than the per capita gross domestic product in this Indian state. While these indicative cost-effectiveness estimates can inform HIV control planning currently, the wide uncertainty range around estimates for several interventions suggest the need for more firm data for estimating cost-effectiveness of HIV prevention interventions in India.

Conventional cancer therapies, the second leading cause of death worldwide, result in serious side effects and, at best, merely extend the patient's lifespan by a few years. Searching for effective prevention is of high priority in both basic and clinical sciences. In recent decades natural products have been considered to be an important source of cancer chemopreventive agents. Red wine polyphenols, which consisted of various powerful antioxidants such as flavonoids and stilbenes, have been implicated in cancer prevention and that promote human health without recognizable side effects. Since resveratrol, a major component of red wine polyphenols, has been studied and reviewed extensively for its chemopreventive activity to interfere with the multi-stage carcinogenesis, this review focuses on recent progress in studies on cancer chemopreventive activities of red wine polyphenol extracts and fractions as well as other red wine polyphenols, like procyanidin B5 analogues and myricetin.

Cancer-related fatigue (CrF) is the most common and disruptive symptom experienced by cancer survivors. We aimed to develop a theory-based, interactive Web-based intervention designed to facilitate self-management and enhance coping with CrF following cancer treatment. The aim of our study was to outline the rationale, decision-making processes, methods, and findings which led to the development of a Web-based intervention to be tested in a feasibility trial. This paper outlines the process and method of development of the intervention. An extensive review of the literature and qualitative research was conducted to establish a therapeutic approach for this intervention, based on theory. The psychological principles used in the development process are outlined, and we also clarify hypothesized causal mechanisms. We describe decision-making processes involved in the development of the content of the intervention, input from the target patient group and stakeholders, the design of the website features, and the initial user testing of the website. The cocreation of the intervention with the experts and service users allowed the design team to ensure that an acceptable intervention was developed. This evidence-based Web-based program is the first intervention of its kind based on self-regulation model theory, with the primary aim of targeting the representations of fatigue and enhancing self-management of CrF, specifically. This research sought to integrate psychological theory, existing evidence of effective interventions, empirically derived principles of Web design, and the views of potential users into the systematic planning and design of the intervention of an easy-to-use website for cancer survivors. ©Teresa Corbett, Jane C Walsh, AnnMarie Groarke, Rona Moss-Morris, Eimear Morrissey, Brian E McGuire.

Evidence-Based Obesity Prevention in Childhood and Adolescence: Critique of Recent Etiological Studies, Preventive Interventions, and Policies123

Reilly, John J.

2012-01-01

Prevention of obesity in childhood and adolescence remains a worthwhile and realistic goal, but preventive efforts have been beset by a number of problems, which are the subject of this review. The review draws on recent systematic reviews and evidence appraisals and has a United Kingdom (UK) perspective because there is a rich evidence base in the United Kingdom that may be helpful to obesity prevention researchers elsewhere. Recent evidence of a leveling off in child and adolescent obesity prevalence in some Western nations should not encourage the belief that the obesity prevention problem has been solved, although a better understanding of recent secular trends might be helpful for prevention strategy in future. An adequate body of evidence provides behavioral targets of preventive interventions, and there are frameworks for prioritizing these targets logically and models for translating them into generalizable interventions with a wide reach (e.g., school-based prevention interventions such as Planet Health). An improved understanding of the “energy gap” that children and adolescents experience would be helpful to the design of preventive interventions and to their tailoring to particular groups. In the United Kingdom, some recent etiological evidence has been taken as indicative of the need for paradigm shifts in obesity prevention, but this evidence from single studies has not been replicated, and paradigm shifts probably occur only rarely. Ensuring that the evidence base on etiology and prevention influences policy effectively remains one of the greatest challenges for childhood obesity researchers. PMID:22798005

Estimating intervention effects of prevention programs: accounting for noncompliance.

Individuals not fully complying with their assigned treatments is a common problem encountered in randomized evaluations of behavioral interventions. Treatment group members rarely attend all sessions or do all "required" activities; control group members sometimes find ways to participate in aspects of the intervention. As a result, there is often interest in estimating both the effect of being assigned to participate in the intervention, as well as the impact of actually participating and doing all of the required activities. Methods known broadly as "complier average causal effects" (CACE) or "instrumental variables" (IV) methods have been developed to estimate this latter effect, but they are more commonly applied in medical and treatment research. Since the use of these statistical techniques in prevention trials has been less widespread, many prevention scientists may not be familiar with the underlying assumptions and limitations of CACE and IV approaches. This paper provides an introduction to these methods, described in the context of randomized controlled trials of two preventive interventions: one for perinatal depression among at-risk women and the other for aggressive disruptive behavior in children. Through these case studies, the underlying assumptions and limitations of these methods are highlighted.

Recurrent urinary tract infections (RUTI) are common in women who are pregnant and may cause serious adverse pregnancy outcomes for both mother and child including preterm birth and small-for-gestational-age babies. Interventions used to prevent RUTI in women who are pregnant can be pharmacological (antibiotics) or non-pharmacological (cranberry products, acupuncture, probiotics and behavioural modifications). So far little is known about the best way to prevent RUTI in pregnant women. To assess the effects of interventions for preventing recurrent urinary tract infections in pregnant women.The primary maternal outcomes were RUTI before birth (variously defined) and preterm birth (before 37 weeks). The primary infant outcomes were small-for-gestational age and total mortality. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (8 June 2012) and reference lists of retrieved articles. Published, unpublished and ongoing randomised controlled trials (RCTs), quasi-RCTs, clustered-randomised trials and abstracts of any intervention (pharmacological and non-pharmacological) for preventing RUTI during pregnancy (compared with another intervention, placebo or with usual care). Two review authors independently evaluated the one identified trial for inclusion and assessed trial quality. Two review authors extracted data. Data were checked for accuracy. The review included one trial involving 200 women. The trial compared a daily dose of nitrofurantoin and close surveillance (regular clinic visit, urine cultures and antibiotics when a positive culture was found) with close surveillance only. No significant differences were found for the primary outcomes: recurrent pyelonephritis (risk ratio (RR) 0.89, 95% confidence interval (CI) 0.31 to 2.53, one study, 167 women), recurrent urinary tract infection before birth (RR 0.30, 95% CI 0.06 to 1.38; one study 167 women) and preterm birth (before 37 weeks) (RR 1.18, 95% CI 0.42 to 3.35; one study 147 women).

It is well documented that cancer is disproportionately distributed in racial/ethnic minority groups and medically underserved communities. In addition, cancer prevention and early detection represent the key defenses to combat cancer. The purpose of this article is to showcase the comprehensive health education and community outreach activities at the H. Lee Moffitt Cancer Center and Research Institute (Moffitt) designed to promote and increase access to and utilization of prevention and early detection services among underserved populations. One of Moffitt's most important conduits for cancer prevention and early detection among underserved populations is through its community education and outreach initiatives, in particular, the Moffitt Program for Outreach Wellness Education and Resources (M-POWER). M-POWER works to empower underserved populations to make positive health choices and increase screening behaviors through strengthening collaboration and partnerships, providing community-based health education/promotion, and increasing access to care. Effective, empowering, and culturally and linguistically competent health education and community outreach, is key to opening the often impenetrable doors of cancer prevention and early detection to this society's most vulnerable populations.

Worldwide, transgender women who engage in sex work have a disproportionate risk for HIV compared with natal male and female sex workers. We reviewed recent epidemiological research on HIV in transgender women and show that transgender women sex workers (TSW) face unique structural, interpersonal, and individual vulnerabilities that contribute to risk for HIV. Only six studies of evidence-based prevention interventions were identified, none of which focused exclusively on TSW. We developed a deterministic model based on findings related to HIV risks and interventions. The model examines HIV prevention approaches in TSW in two settings (Lima, Peru and San Francisco, CA, USA) to identify which interventions would probably achieve the UN goal of 50% reduction in HIV incidence in 10 years. A combination of interventions that achieves small changes in behaviour and low coverage of biomedical interventions was promising in both settings, suggesting that the expansion of prevention services in TSW would be highly effective. However, this expansion needs appropriate sustainable interventions to tackle the upstream drivers of HIV risk and successfully reach this population. Case studies of six countries show context-specific issues that should inform development and implementation of key interventions across heterogeneous settings. We summarise the evidence and knowledge gaps that affect the HIV epidemic in TSW, and propose a research agenda to improve HIV services and policies for this population. PMID:25059941

Fatigue is a prevalent and burdensome symptom for patients with incurable cancer receiving cancer treatment with palliative intent and is associated with reduced quality of life. Psychosocial interventions seem promising for management of fatigue among cancer patients. To assess the effects of psychosocial interventions for fatigue in adult patients with incurable cancer receiving cancer treatment with palliative intent. We searched the following databases: CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, and seven clinical trial registries; we also searched the reference lists of articles. The date of our most recent search was 29 November 2016. We included randomised controlled trials that compared psychosocial interventions in adults aged 18 years or over undergoing cancer treatment with palliative intent for incurable cancer versus usual care or other controls. Psychosocial interventions were defined as various kinds of interventions provided to influence or change cognitions, emotions, behaviours, social interactions, or a combination of these. Psychosocial interventions of interest to this review had to involve at least two interactions between the patient and the care provider in which the care provider gave the patient personal feedback concerning changes sought by these interventions. We included trials that reported fatigue as an outcome of interest. We used standard methodological procedures expected by Cochrane. Two review authors independently considered trials for inclusion in the review, assessed risk of bias, and extracted data, including information on adverse events. We assessed the quality of evidence using GRADE (Grading of Recommendations Assessment, Development, and Evaluation) and created a 'Summary of findings' table. We identified 14 studies (16 reports) that met inclusion criteria for this review and involved 3077 randomised participants in total. Most of these studies included a mixed sample of participants; we obtained data for the subset of

The Intervention Mapping (IM) protocol provides a structured framework to develop, implement, and evaluate complex interventions. The main objective of this review was to identify and describe the content of the interventions developed in the field of cancer with the IM protocol. Secondary objectives were to assess their fidelity to the IM protocol and to review their theoretical frameworks. Medline, Web of Science, PsycINFO, PASCAL, FRANCIS, and BDSP databases were searched. All titles and abstracts were reviewed. A standardized extraction form was developed. All included studies were reviewed by 2 reviewers blinded to each other. Sixteen studies were identified, and these reported 15 interventions. The objectives were to increase cancer screening participation (n = 7), early consultation (n = 1), and aftercare/quality of life among cancer survivors (n = 7). Six reported a complete participatory planning group, and 7 described a complete logic model of the problem. Ten studies described a complete logic model of change. The main theoretical frameworks used were the theory of planned behaviour (n = 8), the transtheoretical model (n = 6), the health belief model (n = 6), and the social cognitive theory (n = 6). The environment was rarely integrated in the interventions (n = 4). Five interventions were reported as effective. Culturally relevant interventions were developed with the IM protocol that were effective to increase cancer screening and reduce social disparities, particularly when they were developed through a participative approach and integrated the environment. Stakeholders' involvement and the role of the environment were heterogeneously integrated in the interventions. Copyright © 2017 John Wiley & Sons, Ltd.

There is a dearth of knowledge regarding factors that may motivate African American adolescents to consume healthier diets. To develop and test cancer prevention messages based on Prospect Theory on motivation to improve dietary intake in African American adolescents and to explore other salient factors that may inform dietary intervention design and implementation in this population. Semistructured in-person qualitative interviews were conducted with 13 African American male and female adolescents, aged 12 to 16 years, in North Carolina. Prospect Theory and message framing were used to guide the design of the 4 sets of diet-related messages related to cancer prevention: short-term, gain-framed; long-term, gain-framed; short-term, loss-framed; and long-term, loss-framed messages. Data were also collected on demographic, behavioral, and psychological factors; usual health behaviors; and preferences for intervention delivery. Most respondents found the gain-framed, short-term messages most salient for both fruits/vegetables (8 [61.5%]) and fat consumption (7 [53.8%]). For fat consumption only, 2 (15.4%) found the loss-framed, short-term messages pertinent; none found the loss-framed, long-term messages relevant for either dietary variable. All indicated interest in participating in a dietary intervention/education program; most preferred the Internet as a channel for intervention delivery. Participants expressed diverse views regarding knowledge, attitudes, and beliefs regarding healthy eating. The gain-framed, short-term messages were most salient for motivating the majority of respondents to consume a healthy diet and most expressed a strong interest in participating in programs about diet and nutrition, with the Internet as the preferred communication channel. Researchers conducting dietary interventions and education initiatives and medical professionals who counsel African American adolescents should consider using Prospect Theory as a theoretical framework

Sexual concerns continue to be poorly addressed for women treated for breast cancer and evidence-based interventions that adequately address these concerns are scarce. The objective of this study was to adapt a telephone-based intimacy enhancement intervention, previously tested in couples facing colorectal cancer, to the needs of women with breast cancer through qualitative focus groups, cognitive interviews, and expert review. Three semistructured qualitative focus groups in partnered posttreatment breast cancer survivors (n = 15) reporting sexual concerns were conducted to investigate experiences of breast cancer-related sexual concerns and intervention preferences. Focus group data were coded using the framework approach to qualitative analysis; 8 key themes were identified and used to develop the content and format of the intervention. Feedback from cognitive interviews with study-naïve breast cancer survivors (n = 4) and expert review of materials were also incorporated in finalizing the intervention materials. Qualitative findings centered on the impact of breast cancer and its treatment on women's sexuality and on the intimate relationship, experiences of helpful and unhelpful coping methods, and explicit intervention preferences. Focus group data were particularly helpful in identifying the scope of educational topics and in determining how to structure intervention skills practice (e.g., intimacy-related communication) to be optimally relevant and helpful for both women and their partners. Cognitive interview feedback helped refine intervention materials. An intimacy enhancement intervention was adapted for women with breast cancer and their partners. This intervention offers a promising, potentially disseminable approach to addressing breast cancer-related sexual concerns. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Persistently increased blood levels of estrogens are associated with an increased risk of breast cancer. Selective estrogen receptor modulators (SERMs) are a class of compounds that act on the estrogen receptor (ER). Several clinical trials have demonstrated the effectiveness of its prophylactic administration. Incidence of invasive ER-positive breast cancer was reduced by SERMs treatment, especially for those women with high risk of developing breast cancer. In this study, we reviewed the clinical application of SERMs in breast cancer prevention. To date, four prospective randomized clinical trials had been performed to test the efficacy of tamoxifen for this purpose. Concerning on the benefit and cost of tamoxifen, various studies from different countries demonstrated that chemoprevention with tamoxifen seemed to be cost-effective for women with a high risk of invasive breast cancer. Based above, tamoxifen was approved for breast cancer prevention by the US Food and Drug Administration in 1998. Raloxifene was also approved for postmenopausal women in 2007 for breast cancer prevention which reduces the risk of invasive breast cancer with a lower risk of unwanted stimulation of endometrium. Thus, raloxifene is considered to have a better clinical possesses as prophylactic agent. Several other agents, such as arzoxifene and lasofoxifene, are currently being investigated in clinic. The American Society of Clinical Oncology and National Comprehensive Cancer Network had published guidelines on breast cancer chemoprevention by SERMs. However, use of tamoxifen and raloxifene for primary breast cancer prevention was still low. A broader educational effort is needed to alert women and primary care physicians that SERMs are available to reduce breast cancer risk.

Modifiable lifestyle factors may reduce the risk of developing breast cancer. Obesity is associated particularly with post-menopausal breast cancer. Diet is important, and exercise equivalent to running for up to 8 hours each week reduces the risk of breast cancer, both in its own right and through reducing obesity. Alcohol consumption may be responsible for 5.8% of breast cancers in Australia and it is recommended to reduce this to two standard drinks per day. Drinking alcohol and smoking increases the risk for breast cancer and, therefore, it is important to quit tobacco smoking. Prolonged use of combined oestrogen and progesterone hormone replacement therapy and oral contraceptives may increase breast cancer risk and this must be factored into individual decisions about their use. Ionising radiation, either from diagnostic or therapeutic radiation or through occupational exposure, is associated with a high incidence of breast cancer and exposure may be reduced in some cases. Tamoxifen chemoprevention may reduce the incidence of oestrogen receptor positive cancer in 51% of women with high risk of breast cancer. Uncommon but serious side effects include thromboembolism and uterine cancer. Raloxifene, which can also reduce osteoporosis, can be used in post-menopausal women and is not associated with the development of uterine cancer. Surgical prophylaxis with bilateral mastectomy and salpingo-oophorectomy can reduce the risk of breast cancer in patients carrying BRCA1 or BRCA2 mutations. For preventive treatments, mammographic screening can identify other women at high risk.

In the U.S., overweight/obesity among African American (AA) girls has become epidemic. Since parental factors may be associated with improved weight status, it is important to understand the empirical evidence for including parents in obesity prevention interventions with AA girls. The purpose of this integrative review was to identify effectiveness and characteristics of obesity prevention interventions for AA girls (6-17 years) and their parent. Included interventions addressed physical activity (PA), dietary/eating behaviors, and body composition. Of 708 studies published through March 2014, eight met inclusion criteria. Though effects were in the intended direction for most, statistically significant effects were found only for dietary intake and eating behavior. Interventions were characterized by exclusion of girls ages 13-17, failure to link parent involvement to child outcomes, the absence of family systems theory, and modest effects. Further research is needed to ascertain the effectiveness of daughter/parent obesity prevention interventions.

Full Text Available Nicole Kiss1,2 1Nutrition and Speech Pathology Department, Peter MacCallum Cancer Centre, East Melbourne, VIC, Australia; 2Department of Cancer Experiences Research, Peter MacCallum Cancer Centre, East Melbourne, VIC, Australia Abstract: Malnutrition and weight loss are prevalent in patients with lung cancer. The impact of malnutrition on patients with cancer, and specifically in patients with lung cancer, has been demonstrated in a large number of studies. Malnutrition has been shown to negatively affect treatment completion, survival, quality of life, physical function, and health care costs. Emerging evidence is providing some insight into which lung cancer patients are at higher nutritional risk. In lung cancer patients treated with radiotherapy, stage III or more disease, treatment with concurrent chemotherapy and the extent of radiotherapy delivered to the esophagus appear to confer a higher risk of weight loss during and post-treatment. Studies investigating nutrition interventions for lung cancer patients have examined intensive dietary counseling, supplementation with fish oils, and interdisciplinary models of nutrition and exercise interventions and show promise for improved outcomes from these interventions. However, further research utilizing these interventions in large clinical trials is required to definitively establish effective interventions in this patient group.

Evidence-based (EB) fall prevention interventions to mitigate patient-specific fall risk factors are readily available but not routinely used in practice. Few studies have examined nurses' perceptions about both the use of these EB interventions and implementation strategies designed to promote their adoption. This article reports qualitative findings of nurses' perceptions about use of EB fall prevention interventions to mitigate patient-specific fall risks, and implementation strategies to promote use of these interventions. The findings revealed five major themes: before-study fall prevention practices, use of EB fall prevention interventions tailored to patient-specific fall risk factors, beneficial implementation strategies, overall impact on approach to fall prevention, and challenges These findings are useful to guide nurses' engagement and use of EB fall prevention practices tailored to patient-specific fall risk factors. © The Author(s) 2016.

Full Text Available Behavioral interventions can prevent the transmission of HIV and sexually transmitted infections. This systematic review and meta-analysis assesses the effectiveness and quality of available evidence of HIV prevention interventions for people living with HIV in high-income settings. Searches were conducted in MEDLINE, EMBASE, PsycINFO, and CDC Compendium of Effective Interventions. Interventions published between January, 1998 and September, 2015 were included. Quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE. Forty-six articles and 63 datasets involving 14,096 individuals met inclusion criteria. Included articles were grouped by intervention type, comparison group and outcome. Few of these had high or moderate quality of evidence and statistically significant effects. One intervention type, group-level health education interventions, were effective in reducing HIV/STI incidence when compared to attention controls. A second intervention type, comprehensive risk counseling and services, was effective in reducing sexual risk behaviors when compared to both active and attention controls. All other intervention types showed no statistically significant effect or had low or very low quality of evidence. Given that the majority of interventions produced low or very low quality of evidence, researchers should commit to rigorous evaluation and high quality reporting of HIV intervention studies.

We examined the interventions used by nurses to prevent pressure ulcers in 3 hospitals in south west Nigeria and perceived barriers to effective nursing pressure ulcer prevention interventions. One hundred ninety-three nurses were purposively selected from neurological, orthopedic, intensive care, and accident and emergency units of participating hospitals. Study sites were 3 teaching hospitals in south west Nigeria (Lagos State University Teaching Hospital, Lagos; University College Hospital, Ibadan; and Obafemi Awolowo Teaching Hospital Ile-Ife). Data were collected via a structured questionnaire designed for this study. It included 3 sections: demographic information, practices used for pressure ulcer prevention, and perceived barriers to prevention. Sections of the questionnaire that queried interventions and perceived barriers to pressure ulcer prevention were evaluated for face and content validity. Reliability was evaluated via internal consistency; the split half reliability was 0.82. Similar practices regarding pressure ulcer prevention were found across the 3 hospitals. The most commonly used intervention was patient repositioning every 2 hours; the least used intervention was completion of a validated pressure ulcer risk scale. Nurses described using interventions that have not proved effective for pressure ulcer prevention such as massaging bony prominences and application of talcum powder. Nurses identified 2 principal factors that act as barriers to successful prevention of pressure ulcers: inadequate manpower and inadequate supply of linens on the wards. Nurses use a combination of evidence-based interventions, along with interventions that have not proved effective for pressure ulcer prevention. We recommend development of national standards for pressure ulcer prevention in Nigeria that are based on current best evidence and consistent with current international guidelines.

In Argentina almost 7% of deaths are due to different cancers with screening strategies. Evaluate knowledge about cancer prevention compared with other tumors. Materials. A descriptive and comparative study. A survey between April and June 2013 in Salta City, province of Salta, Argentina. Correct answers were considered. Statistical analysis: Descriptive (mean and percentage), comparative Chi square Test (significance level Pmama and cervix. 20% (CI 0,13-0,28) knew that colon cancer has a genetic predisposition and 58% (CI 0,48-0,67) about mama. 73% (CI 0,63-0,8) received information about cancer prevention. The main source of information was the physician. 46% (CI 0,36-0,55) received medical care in private institutions. Those who had social security, higher educational levels and medical care in private institutions had better knowledge about cancer prevention except in colon cancer. The global results showed levels below 70% in general but extremely low in colon cancer. Not having social security, receiving medical care in public institutions and having a low educational level are related with poor knowledge about cancer prevention except for colon and prostate cancer.

New perspectives of curcumin in cancer prevention

Park, Wungki; Amin, A.R.M Ruhul; Chen, Zhuo Georgia; Shin, Dong M.

2013-01-01

Numerous natural compounds have been extensively investigated for their potential for cancer prevention over decades. Curcumin, from Curcuma longa, is a highly promising natural compound that can be potentially used for chemoprevention of multiple cancers. Curcumin modulates multiple molecular pathways involved in the lengthy carcinogenesis process to exert its chemopreventive effects through several mechanisms: promoting apoptosis, inhibiting survival signals, scavenging reactive oxidative species (ROS), and reducing the inflammatory cancer microenvironment. Curcumin fulfills the characteristics for an ideal chemopreventive agent with its low toxicity, affordability, and easy accessibility. Nevertheless, the clinical application of curcumin is currently compromised by its poor bioavailability. Here we review the potential of curcumin in cancer prevention, its molecular targets, and action mechanisms. Finally, we suggest specific recommendations to improve its efficacy and bioavailability for clinical applications. PMID:23466484

Purpose The incidence of sexually transmitted infections (STIs) and human immunodeficiency virus (HIV) is high among young Chilean women, and there are no STI or HIV prevention interventions available to them that incorporate technology. The purpose of this study was to investigate the preliminary efficacy of an Internet-based STI and HIV prevention intervention (I-STIPI) for Chilean young women on measures of STI- and HIV-related information, motivation, behavioral skills, and preventive behaviors. Design This is a pretest-posttest study. Forty young Chilean women between 18 and 24 years of age participated in an investigation of the I-STIPI’s preliminary efficacy on STI and HIV prevention-related outcomes between baseline and a postintervention assessment. The intervention consisted of four online modules. Data collection was conducted in Santiago, Chile. Paired-samples t test analysis was used to determine whether there were significant differences in each of the outcome variables. Findings After receiving I-STIPI, women reported a significant increase in levels of STI- and HIV-related knowledge, attitudes toward the use of condoms and perceived self-efficacy, and a reduction of risky sexual behaviors with uncommitted partners. Conclusions The I-STIPI showed promise as an Internet-based intervention that can reduce barriers to accessing preventive interventions and increase STI and HIV preventive behaviors in young Chilean women. Clinical Relevance The study provided important information about the ability of an Internet-based intervention to reduce young women’s risk factors and to provide positive preliminary efficacy on STI- and HIV-related outcomes. Internet-based interventions can eliminate many barriers to receiving prevention interventions and may prove to be cost effective. PMID:25410132

Increasing research is available on the preconditions for child mental health and optimal development in traumatic conditions, whereas less is known how to translate the findings into effective interventions to help traumatized children. This literature review analyses the effectiveness of psychosocial preventive interventions and treatments and their theoretical bases among children traumatized in the context of armed conflicts (war, military violence, terrorism and refugee). The first aim is to evaluate the effectiveness of preventive interventions in preventing emotional distress and impairment and promoting optimal emotional-cognitive and social development. The second task is to analyze the nature of the underlying mechanisms for the success of preventive interventions, and the theoretical premises of the choice of intervention techniques, procedures and tools. We found 16 relevant published studies, but an examination of them revealed that only four of them had experimental designs strong enough that they could be included in the meta-analysis. While the subjective reports of the researchers suggested that systematic preventive interventions were effective in decreasing PTSD and depressive symptoms among children traumatized due to armed conflict, the more objective results of the meta-analysis and the weaknesses in designs uncovered during the meta-analysis undermine such a conclusion. Additionally, a majority of the reported preventive interventions focused only on children's biased cognitive processes and negative emotions, while only a few aimed at influencing multiple domains of child development and improving developmental functioning on emotional, social and psychophysiological levels. It is concluded that substantial additional work needs to be done in developing effective preventive interventions and treatments for children traumatized by exposure to war and violence.

This review is the third update of the Cochrane review "Selenium for preventing cancer". Selenium is a naturally occurring element with both nutritional and toxicological properties. Higher selenium exposure and selenium supplements have been suggested to protect against several types of cancer. To gather and present evidence needed to address two research questions:1. What is the aetiological relationship between selenium exposure and cancer risk in humans?2. Describe the efficacy of selenium supplementation for cancer prevention in humans. We updated electronic searches of the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 2), MEDLINE (Ovid, 2013 to January 2017, week 4), and Embase (2013 to 2017, week 6), as well as searches of clinical trial registries. We included randomised controlled trials (RCTs) and longitudinal observational studies that enrolled adult participants. We performed random-effects (RE) meta-analyses when two or more RCTs were available for a specific outcome. We conducted RE meta-analyses when five or more observational studies were available for a specific outcome. We assessed risk of bias in RCTs and in observational studies using Cochrane's risk assessment tool and the Newcastle-Ottawa Scale, respectively. We considered in the primary analysis data pooled from RCTs with low risk of bias. We assessed the certainty of evidence by using the GRADE approach. We included 83 studies in this updated review: two additional RCTs (10 in total) and a few additional trial reports for previously included studies. RCTs involved 27,232 participants allocated to either selenium supplements or placebo. For analyses of RCTs with low risk of bias, the summary risk ratio (RR) for any cancer incidence was 1.01 (95% confidence interval (CI) 0.93 to 1.10; 3 studies, 19,475 participants; high-certainty evidence). The RR for estimated cancer mortality was 1.02 (95% CI 0.80 to 1.30; 1 study, 17,444 participants). For the most frequently

The 2013 Campus Sexual Violence Elimination Act requires U.S. colleges to provide bystander-based training to reduce sexual violence, but little is known about the efficacy of such programs for preventing violent behavior. This study provides the first multiyear evaluation of a bystander intervention's campus-level impact on reducing interpersonal violence victimization and perpetration behavior on college campuses. First-year students attending three similarly sized public university campuses were randomly selected and invited to complete online surveys in the spring terms of 2010-2013. On one campus, the Green Dot bystander intervention was implemented in 2008 (Intervention, n=2,979) and two comparison campuses had no bystander programming at baseline (Comparison, n=4,132). Data analyses conducted in 2014-2015 compared violence rates by condition over the four survey periods. Multivariable logistic regression was used to estimate violence risk on Intervention relative to Comparison campuses, adjusting for demographic factors and time (2010-2013). Interpersonal violence victimization rates (measured in the past academic year) were 17% lower among students attending the Intervention (46.4%) relative to Comparison (55.7%) campuses (adjusted rate ratio=0.83; 95% CI=0.79, 0.88); a similar pattern held for interpersonal violence perpetration (25.5% in Intervention; 32.2% in Comparison; adjusted rate ratio=0.79; 95% CI=0.71, 0.86). Violence rates were lower on Intervention versus Comparison campuses for unwanted sexual victimization, sexual harassment, stalking, and psychological dating violence victimization and perpetration (pSexual Violence Elimination Act bystander training requirements.

Fatigue is a common symptom in cancer patients that can persist beyond the curative treatment phase. Some evidence has been reported for interventions for fatigue during active treatment. However, to date, there is no systematic review on psychological interventions for fatigue after the completion of curative treatment for cancer. This is a protocol for a systematic review that aims to evaluate the effectiveness of psychological interventions for cancer-related fatigue in post-treatment cancer survivors. This systematic review protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO) database. We will search the Cochrane Central Register of Controlled Trials (CENTRAL; The Cochrane Library), PubMed, MEDLINE, EMBASE, CINAHL, PsycINFO, and relevant sources of grey literature. Randomised controlled trials (RCTs) which have evaluated psychological interventions in adult cancer patients after the completion of treatment, with fatigue as an outcome measure, will be included. Two review authors will independently extract data from the selected studies and assess the methodological quality using the Cochrane Collaboration Risk of Bias Tool. Most existing evidence on cancer-related fatigue is from those in active cancer treatment. This systematic review and meta-analysis will build upon previous evaluations of psychological interventions in people during and after cancer treatment. With the growing need for stage-specific research in cancer, this review seeks to highlight a gap in current practice and to strengthen the evidence base of randomised controlled trials in the area.

Music may be a valuable and low-cost coping strategy for cancer patients. We conducted a systematic review and meta-analysis to identify the psychological and physical effects of music interventions in cancer treatment. We included randomized, controlled trials with adult patients in active cancer treatment exposed to different music interventions versus control conditions. Qualitative studies and systematic reviews were excluded. We identified a total of 2624 records through 2 systematic searches (June 2015 and September 2016) in PubMed, Scopus, EMBASE, Cinahl, Web of Science, Cochrane, and PsycINFO and used Risk of Bias Assessment, GRADE and Checklist for Reporting Music-Based Interventions to evaluate the music applied and quality of the studies. We conducted meta-analyses using Review Manager (version 5.3). PROSPERO reg. no. CRD42015026024. We included 25 RCT's (N = 1784) of which 20 were eligible for the meta-analysis (N = 1565). Music reduced anxiety (SMD -0·80 [95% CI, -1.35 to -0.25]), pain (SMD -0.88 [95% CI -1.45 to -0.32]), and improved mood (SMD -0.55 [95% CI, -0.98 to -0.13]). However, studies were hampered by heterogeneity with I 2 varying between 54% and 96%. Quality of the studies ranged from very low to low. The most effective mode of music intervention appeared to be passive listening to self-selected, recorded music in a single session design. Music may be a tool in reducing anxiety, pain, and improving mood among patients with cancer in active treatment. However, methodological limitations in the studies conducted so far prevent firm conclusions. Copyright © 2017 John Wiley & Sons, Ltd.

Parent-based HIV prevention programming may play an important role in reaching youths early to help establish lifelong patterns of safe and healthy sexual behaviors. Families Matter! is a 5-session, evidence-based behavioral intervention designed for primary caregivers of children aged 9 to 12 years to promote positive parenting and effective parent–child communication about sexuality and sexual risk reduction. The program’s 5-step capacity-building model was implemented with local government, community, and faith-based partners in 8 sub-Saharan African countries with good intervention fidelity and high levels of participant retention. Families Matter! may be useful in other resource-constrained settings. PMID:24028229

Developing preventive mental health interventions for refugee families in resettlement.

Weine, Stevan Merrill

2011-09-01

In refugee resettlement, positive psychosocial outcomes for youth and adults depend to a great extent on their families. Yet refugee families find few empirically based services geared toward them. Preventive mental health interventions that aim to stop, lessen, or delay possible negative individual mental health and behavioral sequelae through improving family and community protective resources in resettled refugee families are needed. This paper describes 8 characteristics that preventive mental health interventions should address to meet the needs of refugee families, including: Feasibility, Acceptability, Culturally Tailored, Multilevel, Time Focused, Prosaicness, Effectiveness, and Adaptability. To address these 8 characteristics in the complex environment of refugee resettlement requires modifying the process of developmental research through incorporating innovative mental health services research strategies, including: resilience framework, community collaboration, mixed methods with focused ethnography, and the comprehensive dynamic trial. A preventive intervention development cycle for refugee families is proposed based on a program of research on refugees and migrants using these services research strategies. Furthering preventive mental health for refugee families also requires new policy directives, multisystemic partnerships, and research training. 2011 © FPI, Inc.

This paper presents projections for cancer mortality, incidence and burden of disease (as disability adjusted life years) for 2005, 2015 and 2030. The projections are based on the latest available WHO mortality estimates from 2002, updated with mortality data from 107 countries and augmented by region and site-specific cancer survival models. Cancer accounted for an estimated 7.6 million deaths in 2005, and 72% of these deaths were in low-income and middle-income countries. For cancer deaths under age 70, 79% are estimated to occur in low-income and middle-income countries. Without intervention, the number of global deaths is projected to rise to 9 million in 2015 and a further 11.5 million in 2030. The rising burden of this disease, especially in low-income and middle-income countries, leads us to propose a global goal for cancer: a 2% reduction per annum over and above that which may happen as a result of current trends in prevention, case management and treatment. Achieving this goal would result in 7.7 million fewer deaths from cancer over the period from 2005 to 2015. More of these deaths will be averted in low-income and middle-income countries than in high-income countries. The scientific knowledge to achieve this goal already exists, and the target could be reached through effective cancer prevention strategies, including tobacco control, hepatitis B vaccination and prevention of cervical cancer.

Child injuries represent an important public health problem. The aim of this paper is to review the current scientific knowledge on interventions designed to prevent child injuries. The current state of knowledge in this area was assessed by means of a specific method involving a review of literature reviews and a classification of health promotion interventions identified in these reviews (rapid reviews). We found a large number of effective or promising programmes devoted to the prevention of the most common child injuries: drowning, burns, falls, poisoning, electrocution, sports and leisure injuries. Some interventions are based on environmental measures, while others are educational or use law and regulatory processes. Some are primary prevention measures, others are secondary prevention measures, while others are multidimensional and can effectively reduce several types of injuries. For example, home safety education and provision of safety equipment, or home-based parenting interventions, can have an impact on injury rates. These findings present a number of limitations due to the marked diversity of the quality of the documents reviewed. It should also be stressed that interventions that are not listed in this article are not necessarily ineffective: they may simply lack a rigorous evaluation enabling them to be identified in our review.

Despite recognition that parents are critical stakeholders in childhood obesity prevention, obesity research has overwhelmingly focused on mothers. In a recent review, fathers represented only 17% of parent participants in >600 observational studies on parenting and childhood obesity. The current study examined the representation of fathers in family interventions to prevent childhood obesity and characteristics of interventions that include fathers compared with those that only include mothers. Eligible studies included family-based interventions for childhood obesity prevention published between 2008 and 2015 identified in a recent systematic review. Data on intervention characteristics were extracted from the original review. Using a standardized coding scheme, these data were augmented with new data on the number of participating fathers/male caregivers and mothers/female caregivers. Out of 85 eligible interventions, 31 (37%) included mothers and fathers, 29 (34%) included only mothers, 1 (1%) included only fathers, and 24 (28%) did not provide information on parent gender. Of the interventions that included fathers, half included 10 or fewer fathers. Across all interventions, fathers represented a mere 6% of parent participants. Father inclusion was more common in interventions targeting families with elementary school-aged children (6-10 years) and those grounded in Ecological Systems Theory, and was less common in interventions focused on very young children (0-1 years) or the prenatal period and those targeting the sleep environment. This study emphasizes the lack of fathers in childhood obesity interventions and highlights a particular need to recruit and engage fathers of young children in prevention efforts.

Full Text Available Introduction: In recent years, evidence has shown the growing trend of published studies on family-oriented interventions in children with cancer. Besides shedding light on the current status of knowledge, a review of the existing evidence can serve an effective step toward designing and implementing appropriate interventions in this domain. Methods: This systematic review was carried out to categorize and report the findings of all types of psychosocial interventions on the family caregivers of children with cancer. The English keywords "family career", "family caregiver", “children with cancer", "psychosocial", "intervention”, “educational", and "childhood cancer" were searched in CINAHL, Web of Science (ISI, PsychINFO, Pubmed and Scopus databanks, and equivalent Persian keywords were searched in the SID of Jihad University, IRANDOC, and IranPsych and Magiran databanks. From among 819 papers found between 1994 and 2014, a total of 17 articles were included in the study after qualitative evaluation. Results: Interventions were often performed on mothers and indicated various interventional approaches. The majority of the interventions were cognitive-behavioral which were reported to be effective in improving the measured criteria such as increasing the quality of life, decreasing emotional distress, anxiety and depression, and increasing adaptive behaviors. Conclusion: The findings were generally reported to be hopeful and most of interventions were reported to have positive effects on the participants, among which behavioral-cognitive interventions were found to show the strongest evidence. Supportive interventions must be considered as an indispensable part of care for children with cancer.

Cancer will continue to be a leading cause of ill health and death unless we can capitalize on the potential for 30-40% of these cancers to be prevented. In this light, cancer prevention represents an enormous opportunity for public health, potentially saving much of the pain, anguish, and cost associated with treating cancer. However, there is a challenge for governments, and the wider community, in prioritizing cancer prevention activities, especially given increasing financial constraints. This paper describes a method for identifying cancer prevention priorities. This method synthesizes detailed cancer statistics, expert opinion, and the published literature for the priority setting process. The process contains four steps: assessing the impact of cancer types; identifying cancers with the greatest impact; considering opportunities for prevention; and combining information on impact and preventability. The strength of our approach is that it is straightforward, transparent and reproducible for other settings. Applying this method in Western Australia produced a priority list of seven adult cancers which were identified as having not only the biggest impact on the community but also the best opportunities for prevention. Work conducted in an additional project phase went on to present data on these priority cancers to a public consultation and develop an agenda for action in cancer prevention.

The Child Anxiety Prevention Study: intervention model and primary outcomes.

Ginsburg, Golda S

2009-06-01

The article presents the intervention model and primary outcomes of a preventive intervention designed to reduce anxiety symptoms and prevent the onset of anxiety disorders in the offspring of parents with anxiety disorders. Participants were 40 volunteer children (mean age = 8.94 years; 45% girls; 90% Caucasian) whose parents met criteria for a broad range of anxiety disorders. Families were randomly assigned to an 8-week cognitive-behavioral intervention, the Coping and Promoting Strength program (CAPS; n = 20) or a wait list control condition (WL; n = 20). Independent evaluators (IEs) conducted diagnostic interviews, and children and parents completed measures of anxiety symptoms. Assessments were conducted pre- and postintervention and 6 and 12 months after the postintervention assessment. On the basis of intent to treat analyses, 30% of the children in the WL group developed an anxiety disorder by the 1-year follow-up compared with 0% in the CAPS group. IE and parent-reported (but not child-reported) levels of anxiety showed significant decreases from the preintervention assessment to the 1-year follow-up assessment in the CAPS but not the WL group. Parental satisfaction with the intervention was high. Findings suggest that a family-based intervention may prevent the onset of anxiety disorders in the offspring of parents with anxiety disorders.

Diet, genes, and microbes: complexities of colon cancer prevention.

Science.gov (United States)

Birt, Diane F; Phillips, Gregory J

2014-01-01

Colorectal cancer is one of the leading causes of cancer-related deaths in the United States, and generally, as countries climb the economic ladder, their rates of colon cancer increase. Colon cancer was an early disease where key genetic mutations were identified as important in disease progression, and there is considerable interest in determining whether specific mutations sensitize the colon to cancer prevention strategies. Epidemiological studies have revealed that fiber- and vegetable-rich diets and physical activity are associated with reduced rates of colon cancer, while consumption of red and processed meat, or alcoholic beverages, and overconsumption as reflected in obesity are associated with increased rates. Animal studies have probed these effects and suggested directions for further refinement of diet in colon cancer prevention. Recently a central role for the microorganisms in the gastrointestinal tract in colon cancer development is being probed, and it is hypothesized that the microbes may integrate diet and host genetics in the etiology of the disease. This review provides background on dietary, genetic, and microbial impacts on colon cancer and describes an ongoing project using rodent models to assess the ability of digestion-resistant starch in the integration of these factors with the goal of furthering colon cancer prevention.

This article provides the findings of a survey of previous and current students in the UDC/GU-LCCC master's degree program. This master's degree program, Cancer Biology, Prevention, and Control is administered and taught jointly by faculty of a Minority Serving Institution, the University of the District of Columbia, and the Lombardi Comprehensive Cancer Center to incorporate the strengths of a community-based school with a research intensive medical center. The program was initiated in 2008 through agreements with both University administrations and funding from the National Cancer Institute. The master's degree program is 36 credits with a focus on coursework in biostatistics, epidemiology, tumor biology, cancer prevention, medical ethics, and cancer outreach program design. For two semesters during the second year, students work full-time with a faculty person on a laboratory or outreach project that is a requirement for graduation. Students are supported and encouraged to transition to a doctoral degree after they obtain the master's and many of them are currently in doctorate programs. Since the inception of the program, 45 students have initiated the course of study, 28 have completed the program, and 13 are currently enrolled in the program. The survey was designed to track the students in their current activities, as well as determine which courses, program enhancements, and research experiences were the least and most useful, and to discern students' perceptions of knowledge acquired on various aspects of Cancer Biology Prevention, and Control Master's Program. Thirty of the 35 individuals to whom email requests were sent responded to the survey, for a response rate of 85.7%. The results of this study will inform the strengthening of the Cancer Biology program by the Education Advisory Committee. They can also be used in the development of comparable collaborative master's degree programs designed to address the significant disparities in prevalence of

Studies evaluating the benefit and safety of combined behavioral and biomedical interventions are needed, especially considering the attributable fraction of each component. Integration of behavioral and biomedical interventions is required to achieve complete suppression of the virus, and thus reducing viral replication, infectivity and the number of cases.

As part of a 2-day conference on October 15 and 16, 2009, a nine-member task force composed of scientists, clinicians, educators, administrators, and students from across the USA was formed to discuss research, discovery, and technology obstacles to progress in cancer prevention and control, specifically those related to the cancer prevention workforce. This article summarizes the task force's findings on the current state of the cancer prevention workforce in this area and its needs for the future. The task force identified two types of barriers impeding the current cancer prevention workforce in research, discovery, and technology from reaching its fullest potential: (1) limited cross-disciplinary research opportunities with underutilization of some disciplines is hampering discovery and research in cancer prevention, and (2) new research avenues are not being investigated because technology development and implementation are lagging. Examples of impediments and desired outcomes are provided in each of these areas. Recommended solutions to these problems are based on the goals of enhancing the current cancer prevention workforce and accelerating the pace of discovery and clinical translation.

Full Text Available Cervical cancer is a deadly cancer that clutches lives of the women in most of the cases due to lack of consciousness about the disease in the developing countries. It remains a threat which is second only to breast cancer in overall disease burden for women throughout the world. Cervical cancer is almost a preventable disease by prophylactic vaccine and routine screening. Both Cervarix and Gardasil vaccines have been effective in preventing persistent infection with targeted HPV types and in preventing cervical intraepithelial lesions. It is safe and nearly 100% effective if given before onset of sexual activity. This review article is aimed to explore different aspects of this vaccine as well as to develop awareness among health professionals of different disciplines.

Full Text Available The purpose of this study was to examine the career paths of alumni from the National Cancer Institute (NCI Cancer Prevention Fellowship Program (CPFP, a structured in-house postdoctoral training program of 3-4 years duration, and specifically what proportion of the alumni were currently performing cancer prevention-related activities. The analyses here included 119 CPFP alumni and 85 unsuccessful CPFP applicants, all of whom completed postdoctoral training between 1987-2011 and are currently employed. Postdoctoral training experiences and current career outcomes data were collected via online surveys. Differences between groups were assessed using chi-square and Fisher's exact test p-values and subsequent regression analyses adjusted for differences between the groups. Compared to 15.3% of unsuccessful CPFP applicants, 52.1% of CPFP alumni (odds ratio [OR] = 4.99, 95% confidence interval [95% CI: 1.91-13.0 were currently spending the majority of their time working in cancer prevention. Among those doing any cancer prevention-focused work, 54.3% of CPFP alumni spent the majority of their time performing cancer prevention research activities when compared to 25.5% of unsuccessful applicants (OR = 4.26, 95% CI: 1.38-13.2. In addition to the independent effect of the NCI CPFP, scientific discipline, and employment sector were also associated with currently working in cancer prevention and involvement in cancer prevention research-related activities. These results from a structured postdoctoral training program are relevant not only to the cancer prevention community but also to those interested in evaluating alignment of postdoctoral training programs with available and desired career paths more broadly.

The human papillomavirus (HPV) is associated with the diagnosis of anal, penile, and oropharyngeal cancers in men. Evidence indicates that correct condom use in addition to obtaining the HPV vaccine provides the greatest protection from HPV infections. To explore young men's beliefs and behavioral intention in relation to receiving the HPV vaccine and using a condom correctly and consistently for sexual contact. A cross-sectional study underpinned by the theory of planned behavior (TPB) was conducted with male participants (n = 359, 18-28 years) who completed an online survey. Descriptive, correlational, and hierarchical regression analyses were performed on both status variables and variables of the TPB. Subjective norms (β = 0.519, P HPV vaccine, while relationship status (β = -0.215, P HPV vaccine and 44% in intention to use a condom were explained by the TPB model. Results from this study will impact on future sexual health research, education programs, and interventions for both HPV preventative behaviors towards the elimination of HPV-related cancers in men.

Hashemi, Seyed Hesam Bani; Karimi, Samieh; Mahboobi, Hamidreza

2014-01-01

Breast cancer is the second most common cause of death from cancer among women. Lifestyle changes are shown to be important in the prevention of breast cancer. Diet, physical activity, smoking, alcohol use, and vitamin and mineral use are key factors influencing the risk of breast cancer among women. Because these factors are related to each other, it is difficult to assess their individual roles in breast cancer. Some of these factors are alterable, meaning that women can decrease their risk...

Facial aging is a complex interplay of extrinsic and intrinsic factors leading to progressive changes in the skin, subcutaneous tissue, and bone. Clinical experience suggests that early aesthetic intervention may slow the signs of aging, but treatment in the absence of symptoms or with minimal signs of aging has not yet been properly addressed. To provide treatment recommendations for primary prevention and early intervention in individuals with no or minimal signs of aging. Fourteen specialists in aesthetic medicine convened over a full-day meeting under the guidance of a certified moderator. Tailored treatment recommendations have been provided for prevention and early intervention of fine wrinkles, static lines and folds, irregular pigmentation, laxity, and subcutaneous volume loss by protecting the epidermis, stimulating neocollagenesis, reducing hyperkinetic musculature, and reinforcing supporting structures. Preventive measures and early therapeutic interventions that may alter the course of facial aging were defined. Further studies are needed to support these recommendations with the best possible evidence. J Drugs Dermatol. 2017;16(9):846-854..

Web and mobile technologies appear to hold promise for delivering evidence-informed and evidence-based intervention to cancer survivors and others living with trauma and other psychological concerns. Health-space.net was developed as a comprehensive online social networking and coping skills training program for cancer survivors living with distress. The purpose of this study was to evaluate the effects of a 12-week social networking intervention on distress, depression, anxiety, vigor, and fatigue in cancer survivors reporting high levels of cancer-related distress. We recruited 347 participants from a local cancer registry and internet, and all were randomized to either a 12-week waiting list control group or to immediate access to the intervention. Intervention participants received secure access to the study website, which provided extensive social networking capabilities and coping skills training exercises facilitated by a professional facilitator. Across time, the prevalence of clinically significant depression symptoms declined from 67 to 34 % in both conditions. The health-space.net intervention had greater declines in fatigue than the waitlist control group, but the intervention did not improve outcomes for depression, trauma-related anxiety symptoms, or overall mood disturbance. For those with more severe levels of anxiety at baseline, greater engagement with the intervention was associated with higher levels of symptom reduction over time. The intervention resulted in small but significant effects on fatigue but not other primary or secondary outcomes. Results suggest that this social networking intervention may be most effective for those who have distress that is not associated with high levels of anxiety symptoms or very poor overall psychological functioning. The trial was registered with the ClinicalTrials.gov database ( ClinicalTrials.gov #NCT01976949).

The Effects of Expressive Writing Interventions for Patients With Cancer: A Meta-Analysis.

To evaluate the effects of expressive writing (EW) interventions in patients with cancer.
. Electronic databases searched included both international and Korean databases through January 2015.
. Of the 20 trials that met the eligibility criteria of this review, a meta-analysis was conducted of 14 articles involving 13 randomized and 1 nonrandomized trials with 1,718 patients with cancer. EW interventions were compared with a neutral writing intervention or usual care (no writing). A significant small effect was noted on relieving cancer symptoms; however, the effects on psychological and cognitive outcomes were not significant. When subgroup analysis by control condition was performed, a significant effect on health-related quality of life was found between the EW intervention group and the usual care group. 
. EW had significant small effects only on cancer symptoms. The findings suggest that the traditional EW intervention protocol may need to be intensified to confirm its effect on patients with cancer.
. Current evidence for EW as a nursing intervention for improving physical, psychological, and cognitive outcomes among patients with cancer is promising, but not conclusive.

Scientific advances have improved our ability to target cancer interventions to individuals who will benefit most and spare the risks and costs to those who will derive little benefit or even be harmed. Several approaches are currently used for targeting interventions for cancer risk reduction, screening, and treatment, including risk prediction algorithms for identifying high-risk subgroups and diagnostic tests for tumor markers and germline genetic mutations. Economic evaluation can inform decisions about the use of targeted interventions, which may be more costly than traditional strategies. However, assessing the impact of a targeted intervention on costs and health outcomes requires explicit consideration of the method of targeting. In this study, we describe the importance of this principle by reviewing published cost-effectiveness analyses of targeted interventions in breast cancer. Few studies we identified explicitly evaluated the relationships among the method of targeting, the accuracy of the targeting test, and outcomes of the targeted intervention. Those that did found that characteristics of targeting tests had a substantial impact on outcomes. We posit that the method of targeting and the outcomes of a targeted intervention are inextricably linked and recommend that cost-effectiveness analyses of targeted interventions explicitly consider costs and outcomes of the method of targeting.
