RESUMO

BACKGROUND: A substantial proportion of patients with stage III colorectal cancer (CRC) are older than 70 years. Optimal adjuvant chemotherapy (AC) for older patients (OP) continues to be debated, with subgroup analyses of randomized trials not demonstrating a survival benefit from the addition of oxaliplatin to a fluoropyrimidine backbone. PATIENTS AND METHODS: We analyzed the multisite Australian ACCORD registry, which prospectively collects patient, tumor and treatment data along with long term clinical follow-up. We compared OP (≥70) with stage III CRC to younger patients ([YP] <70), including the proportion recommended AC and any reasons for not prescribing AC. AC administration, regimen choice, completion rates, and survival outcomes were also examined. RESULTS: One thousand five hundred twelve patients enrolled in the ACCORD registry from 2005 to 2018 were included. Median follow-up was 57.0 months. Compared to the 827 YP, the 685 OP were less likely to be offered AC (71.5% vs. 96.5%, P < .0001) and when offered, were more likely to decline treatment (15.1% vs. 2.8%, P < .0001). Ultimately, 60.0% of OP and 93.7% of YP received AC (P < .0001). OP were less likely to receive oxaliplatin (27.5% vs. 84.7%, P < .0001) and to complete AC (75.9% vs. 85.7%, P < .0001). The probability of remaining recurrence-free was significantly higher in OP who received AC compared to those not treated (HR 0.73, P = .04) but not significantly improved with the addition of oxaliplatin (HR 0.75, P = .18). CONCLUSION: OP were less likely than YP to receive AC. Receipt of AC reduced recurrences in OP, supporting its use, although no significant benefit was observed from the addition of oxaliplatin.

RESUMO

INTRODUCTION: To promote comprehensive care of patients throughout the androgen deprivation therapy (ADT) prescribing process, the Prostate Cancer 360 (PC360) Working Group developed monitoring and management recommendations intended to mitigate or prevent ADT-associated adverse events. METHODS: The PC360 Working Group included 14 interdisciplinary experts with a dedicated clinical interest in prostate cancer and ADT management. The working group defined challenges associated with ADT adverse event management and then collaboratively developed comprehensive care recommendations intended to be practical for ADT prescribers. RESULTS: The PC360 Working Group developed both overarching recommendations for ADT adverse event management and specific recommendations across 5 domains (cardiometabolic, bone, sexual, psychological, and lifestyle). The working group recommends an interdisciplinary, team-based approach wherein the ADT prescriber retains an oversight role for ADT management while empowering patients and their primary and specialty care providers to manage risk factors. The PC360 recommendations also emphasize the importance of proactive patient education that involves partners or other support providers. Recommended monitoring and assessment tools, risk factor management, and patient counseling points are also included for the 5 identified domains, with an emphasis on lifestyle and behavioral interventions that can improve quality of life and reduce the risk for ADT-associated complications. CONCLUSIONS: Comprehensive care of patients receiving ADT requires early and ongoing coordinated management of a variety of health domains, including cardiometabolic, bone, sexual, psychological health. Patient education and primary care provider involvement should begin prior to ADT initiation and continue throughout treatment to improve patient and partner quality of life.

RESUMO

Autoimmunity is a multifaceted disorder influenced by both genetic and environmental factors, and metal exposure has been implicated as a potential catalyst, especially in autoimmune diseases affecting the central nervous system. Notably, metals like mercury, lead, and aluminum exhibit well-established neurotoxic effects, yet the precise mechanisms by which they elicit autoimmune responses in susceptible individuals remain unclear. Recent studies propose that metal-induced autoimmunity may arise from direct toxic effects on immune cells and tissues, coupled with indirect impacts on the gut microbiome and the blood-brain barrier. These effects can activate self-reactive T cells, prompting the production of autoantibodies, inflammatory responses, and tissue damage. Diagnosing metal-induced autoimmunity proves challenging due to nonspecific symptoms and a lack of reliable biomarkers. Treatment typically involves chelation therapy to eliminate excess metals and immunomodulatory agents to suppress autoimmune responses. Prevention strategies include lifestyle adjustments to reduce metal exposure and avoiding occupational and environmental risks. Prognosis is generally favorable with proper treatment; however, untreated cases may lead to autoimmune disorder progression and irreversible organ damage, particularly in the brain. Future research aims to identify genetic and environmental risk factors, enhance diagnostic precision, and explore novel treatment approaches for improved prevention and management of this intricate and debilitating disease.

RESUMO

Late-life dementia is a growing public health concern lacking effective treatment. Neurodegenerative disorders such as Alzheimer's disease (AD) develop over a preclinical period of many years beginning in midlife. The prevalence of insulin resistance, a prominent risk factor for late-life dementia, also accelerates in middle-age. Consumption of berry fruits, including strawberries, has been shown to influence metabolism as well as cognitive performance suggesting potential to mitigate risk for dementia. In this controlled trial, we enrolled overweight middle-aged men and women with insulin resistance and subjective cognitive decline and performed a 12-week intervention with daily administration of whole-fruit strawberry powder. Diet records showed that participants in both groups maintained the prescribed abstinence from berry product consumption outside the study. We observed diminished memory interference (p = 0.02; Cohen's f = 0.45) and a reduction of depressive symptoms (p = 0.04; Cohen's f = 0.39) for the strawberry-treated participants; benefits consistent with improved executive ability. However, there was no effect of the intervention on metabolic measures, possibly a consequence of the sample size, length of the intervention, or comparatively low anthocyanin dose. Anti-inflammatory actions of anthocyanins were considered as a primary mechanistic factor. The findings support the notion that strawberry supplementation has a role in dementia risk reduction when introduced in midlife. However, further investigation with longer intervention periods, larger samples, and differing dosing regimens will be required to assess the benefits of strawberry intake with respect to cognition and metabolic function in the context of aging.

RESUMO

Introduction Both osteoporosis and osteopenia are prevalent public health concerns worldwide and can lead to debilitating bone fractures. This study aimed to assess the efficacy of Asthiposhak® Tablets in individuals with Asthikshaya (osteopenia) by measuring changes in the bone mineral density (BMD) score before and after the intervention, specifically between visit 1 (baseline) and visit 8 (after 180 days of treatment). Methods The single-arm study involved the screening of participants for Asthikshaya (osteopenia) using baseline investigations, which included a bone mineral density (BMD) assessment through a dual-energy X-ray absorptiometry (DEXA) scan. A total of 36 participants were enrolled in the study, who took two Asthiposhak Tablets three times a day with lukewarm water, for a period of 180 days. Safety assessments, along with evaluations of BMD (DEXA Scan), Ayurvedic Symptom Score, and serum biochemical markers, were conducted through blood investigations. Efficacy and safety data were analyzed using 'intention-to-treat' analysis. Descriptive statistics were used to express data in percentages, mean ± SD, or median (IQR). Data at different intervals were compared using paired t-tests or Wilcoxon signed-rank tests. One-way analysis of variance (ANOVA) with Bonferroni correction tested the significance between visits for the Ayurvedic Symptom Score, and Friedman's two-way analysis of variance by ranks measured differences in vital parameters. The significance level used was p<0.05. Results Out of the initially recruited 36 participants, 30 successfully completed the study, consisting of 12 males and 18 females, with an age range of 40 to 70 years and a mean age of 51.33 years. After 180 days of treatment with Asthiposhak Tablets, a statistically significant (p<0.05) improvement in hip and spine BMD (T-score) was observed. Additionally, significant reductions in the mean Total Ayurvedic Symptom Score were noted at both 90 and 180 days of treatment compared to day 0. Moreover, the levels of bone-specific alkaline phosphatase and osteocalcin, serum bone markers, showed statistically significant (p<0.05) reduction after 180 days of treatment compared to day 0. Importantly, all safety variables, including laboratory investigations, remained within the normal range following the 180-day treatment with Asthiposhak Tablets. Conclusion Asthiposhak Tablets exhibited significant efficacy in enhancing both BMD (T-score) and Ayurvedic Symptom Score, thereby substantiating their osteoprotective potential in individuals with Asthikshaya (osteopenia). Furthermore, the tablets were found to reduce the levels of biochemical markers, such as serum bone-specific alkaline phosphatase and osteocalcin, suggesting their anti-resorptive action.

RESUMO

BACKGROUND: While additional folic acid (FA) treatment has a neutral effect on lowering overall vascular risk in countries that mandate FA fortification of food, meta-analytic data suggest that folate supplementation reduces stroke risk in certain patient subgroups, and among people living in countries without mandatory folate food fortification. However, the burden of folate deficiency among adults with stroke in the world's poorest continent is unknown. PURPOSE: To assess the prevalence and predictors of folate deficiency among recent ischemic stroke survivors. METHODS: We analyzed data among consecutively encountered ischemic stroke patients aged ≥18 years at a tertiary medical center in Kumasi, Ghana between 10/2020 - 08/2021. We identified a modest sample of stroke free adults to serve as a comparator group. Fasting serum folate was measured using a radioimmunoassay and a cut-off of 4ng/mL used to define folate deficiency. Factors associated with serum folate concentration were assessed using a multilinear regression model. RESULTS: Comparing stroke cases (n = 116) with stroke-free comparators (n = 20), mean folate concentration was lower among stroke cases (7 ng/ml vs. 10.2 ng/ml, p = 0.004). Frequency of folate deficiency was higher among stroke cases vs. stroke-free controls (31% vs 5%, p = 0.02). Male sex (beta coefficient of -2.6 (95% CI: -4.2, -0.9) and LDL (ß: -0.76; -1.4, -0.07) were significantly associated with serum folate concentration. CONCLUSION: Almost one in three ischemic stroke survivors have folate deficiency potentially accentuating their risk for further adverse atherosclerotic events in a setting without folate fortification. A clinical trial of folate supplementation among stroke survivors is warranted.

RESUMO

Dyslipidemia is a treatable risk factor for atherosclerotic cardiovascular disease that can be addressed through lifestyle changes and/or lipid-lowering therapies. Adherence to statins can be a clinical challenge in some patients due to statin-associated muscle symptoms and other side effects. There is a growing interest in integrative cardiology and nutraceuticals in the management of dyslipidemia, as some patients desire or are actively seeking a more natural approach. These agents have been used in patients with and without established atherosclerotic cardiovascular disease. We provide an updated review of the evidence on many new and emerging nutraceuticals. We describe the mechanism of action, lipid-lowering effects, and side effects of many nutraceuticals, including red yeast rice, bergamot and others.

RESUMO

INTRODUCTION: The UK Government partnered with industry to tackle cardiovascular disease (CVD) in the first NHS population health agreement. The ambition was to prevent 150 000 strokes, heart attacks and dementia cases over the next 10 years with a new siRNA LDL-C lowering therapy (Inclisiran) delivered within Integrated Care Services by primary care to support a comprehensive approach to lipid management. Following the approval of inclisiran, and guidance published by the National Institute for Health & Care Excellence (NICE) on its use, this paper has been created by a UK general practice to share real-world observations of cases and the potential service benefits of rolling out this innovative drug treatment. The process of identifying patients at risk of atherosclerotic cardiovascular disease (ASCVD) and lessons learned from implementing in practice is also addressed. Workstreams were developed to rapidly roll out a low clinical burden enhanced lipid management program incorporating siRNA LDL-C lowering therapy into primary care practice. APPROACH/METHOD: (1) Multi-disciplinary team (MDT) education program based on freely available Academic Health Science Network (AHSN), National Institute for Health & Care Excellence (NICE), and commercial materials. (2) Automated searches using a software program were run to identify "at-risk" patients alongside manual case-finding in everyday clinics. (3) Patients were invited for review using multi-channel modalities. (4) Where appropriate, treatment was commenced after consent was obtained. (5) Automated recall systems are used to ensure follow-up; initially at 3 months, then every 6 months. DISCUSSION AND CONCLUSIONS: Enhanced lipid management as a secondary prevention measure is achievable in line with national guidance and objectives. The methodology and education/training processes used in combination with reconstructing the management process can help practice staff realize the program benefits, which in turn can lead to a shift in behavior where all staff embed manual case-finding of high-risk patients into everyday consultations and reviews; enabling rapid identification of eligible patients. Taking a multi-disciplinary, holistic approach to new initiatives reduces service burden, particularly for GPs. Leveraging resources from the AHSN and others removes additional training pressures often associated with new initiatives and provides a wealth of educational material to support primary care MDT upskilling.

RESUMO

OBJECTIVE: The objective of this study was to determine the proportion of patients meeting the National Comprehensive Cancer Network (NCCN)'s BRCA genetic testing criteria prior to a diagnosis of a BRCA-related cancer. METHODS: This was a cross-sectional study of patients with BRCA pathogenic variants and a diagnosis of a BRCA-related cancer. Patients were included if they had known dates of genetic testing and cancer diagnosis. NCCN criteria (version 2.2021) were applied to determine if patients met criteria for testing before a BRCA-related cancer diagnosis. The outcome of interest was the proportion of patients undergoing genetic testing following a diagnosis of a BRCA-related cancer who qualified for genetic testing based on NCCN criteria. Chi-square, Mann-Whitney U test, and logistic regression were performed with significance at p < 0.05. RESULTS: Of 270 patients with a BRCA-related cancer, 229 (85%) underwent genetic testing after a cancer diagnosis. Most patients (97%) met at least one NCCN criteria for BRCA testing; 166 (73%) of patients who were tested following a BRCA-related cancer diagnosis also met the criteria for testing by family history. Publicly insured or uninsured patients were three times more likely to undergo BRCA testing after a diagnosis of cancer (odds ratio [OR] 3.03, 95% confidence interval [CI] 1.09-8.40). Patients with a family history of pathogenic variants were more likely to undergo testing before a cancer diagnosis (OR 0.10, 95% CI 0.05-0.23). CONCLUSION: Most patients with BRCA-associated cancers undergo genetic testing after their cancer diagnosis. Increased education on genetic testing criteria and novel methods to improve testing are desperately needed.

RESUMO

Guava (Psidium guajava L.) tree (Myrtaceae family) bears fruit rich in vitamins, fiber, and other nutrients. While native to Latin America, guava is grown in many tropical and subtropical regions across the globe where it has long been used in traditional medicine to treat a myriad of ailments. Guava has been shown to exhibit a number of biological and pharmacological activities, such as antioxidant, anti-inflammatory, immunomodulatory, antimicrobial, antidiabetic, and anticancer properties. Several parts of the plant, including the leaves, fruits, seeds, peels, pulp, bark, and oil, produce phytochemicals with medicinal properties. Emerging research has found that guava bioactive phytochemicals exert antitumorigenic effects against various human malignancies through multiple mechanisms. While there are numerous individual studies that document the anticancer effects of guava constituents, an up-to-date, comprehensive, and critical review of available research data has not been performed. Therefore, the purpose of this review is to present a complete analysis of the cancer preventive and anticancer therapeutic potential of guava-derived products and guava constituents, with a focus on the cellular and molecular mechanisms of action. The bioavailability, pharmacokinetics, and toxicity of guava as well as limitations, challenges, and future directions of research have also been discussed.

RESUMO

This review shows that relatively simple changes to diet and lifestyle can significantly, and rapidly, reduce the risks associated with coronavirus disease 2019 (COVID-19) in terms of infection risk, severity of disease, and even disease-related mortality. A wide range of interventions including regular exercise, adequate sleep, plant-based diets, maintenance of healthy weight, dietary supplementation, and time in nature have each been shown to have beneficial effects for supporting more positive health outcomes with COVID-19, in addition to promoting better overall health. This paper brings together literature from these areas and presents the argument that non-pharmaceutical approaches should not be overlooked in our response to COVID-19. It is noted that, in several cases, interventions discussed result in risk reductions equivalent to, or even greater than, those associated with currently available vaccines. Where the balance of evidence suggests benefits, and the risk is minimal to none, it is suggested that communicating the power of individual actions to the public becomes morally imperative. Further, many lives could be saved, and many harms from the vaccine mandates avoided, if we were willing to embrace this lifestyle-centred approach in our efforts to deal with COVID-19.

RESUMO

@#Breast cancer, the most common malignancy in the world, also causes the most death cases of women among malignancies. Breast cancer risk reduction guidelines (version 2023) was updated by National Comprehensive Cancer Network (NCCN). Based on high-level evidences from evidence-based medicine and the latest research progress, the guidelines provided standardized guidance for breast cancer risk assessment and risk reduction strategies for individuals without a history of invasive breast cancer or ductal carcinoma in situ, which has attracted widespread attention from clinicians worldwide. Breast cancer is also the most common malignancy in Chinese women, and the number of newly diagnosed breast cancer cases each year in China ranks first in the world due to the large population, so the breast cancer prevention has become a major public health challenge in China. Aimed to provide reference for breast cancer prevention in China, this article interpreted the guidelines (the new version) based on the characteristics of breast structure in Asian women and the epidemiological characteristics of breast cancer in China.

RESUMO

Machine learning (ML) is a novel method of data analysis with potential to overcome limitations of traditional composting experiments. In this study, four ML models (multi-layer perceptron regression, support vector regression, decision tree regression, and gradient boosting regression) were integrated with genetic algorithm to predict and optimize heavy metal immobilization during composting. Gradient boosting regression performed best among the four models for predicting both heavy metal bioavailability variations and immobilization. Gradient boosting regression-based feature importance analysis revealed that the heavy metal initial bioavailability factor, total phosphorus, and composting duration were the determinant factors for heavy metal bioavailability variations (together contributing >75%). After genetic algorithm optimization, the maximum immobilization rates of Cu, Zn, Cd, As, and Cr were 79.53, 31.30, 14.91, 46.25, and 66.27%, respectively, superior to over 90% of the measured data. These findings demonstrate the potential application of ML to risk-control for heavy metals in livestock manure composting.

RESUMO

Given the long induction time of many cancers and the fact that modifiable risk factors (e.g., cigarette smoking) including preventive factors (e.g., human papillomavirus [HPV] vaccination, healthy dietary and physical activity patterns) are influenced in adolescence, educating adolescents about cancer causation and risk reduction may have a large impact on reducing the cancer burden. We conducted a systematic review of literature evaluating the impact of cancer education interventions on adolescent knowledge of cancer risk reduction. We searched for articles published from 2000 to 2019 and identified 33 studies meeting our criteria. Given the methodological heterogeneity across studies, we briefly assessed effectiveness but focused on examining the design of the intervention and study. The majority of studies took place outside of the United States (67%). Most studies solely addressed skin or cervical cancer (67%) with only 18% (n = 6) discussing multiple cancers. The majority of interventions were a single-session (55%), did not involve a control or comparison group (67%), and were evaluated using a pre-test and a single post-test (61%); some studies administered multiple post-tests. Few studies (12%) investigated adolescents' knowledge of lifestyle and environmental risk factors at both the individual and community level. Most studies (94%) reported improvement in knowledge following an intervention. Our review revealed wide methodological variation and a deficit in research evaluating interventions that address multiple cancer types and risk factors. Future research should robustly test whether comprehensive cancer education for adolescents can reduce the cancer burden, particularly in communities with major cancer health disparities.

RESUMO

AIM: To review the literature exploring how general practice nurses support lifestyle risk reduction. DESIGN: Integrative literature review. SOURCES: CINAHL, Emcare, MEDLINE, Proquest and Scopus were searched for peer-reviewed primary research published in English from 2010 to 2022. METHODS: Sixteen papers met the inclusion criteria and were assessed for methodological quality using the Mixed Methods Appraisal Tool. Findings were extracted and thematically analysed. RESULTS: Four themes described general practice nurses: (1) Establishing relational connections; (2) Empowering active participation; (3) Engaging mutual motivation and (4) Enabling confident action. General practice nurses used complex interpersonal, risk communication and health coaching skills to build collaborative partnerships that supported patients' self-determination and self-efficacy. While mutual motivation and confidence were reciprocally enabling, gaps in skills, experience and knowledge plus time, resource and role constraints limited general practice nurses' ability to support lifestyle risk reduction. CONCLUSION: General practice nurses play a key role in lifestyle risk reduction. Ongoing education, funding, organizational and professional support are needed to enhance their commitment, confidence and capacity. IMPACT: What problem did the study address? While general practice nurses play a key role in health promotion and risk reduction, their potential is yet to be fully realized. Research examining methods by which nurses working in general practice support lifestyle risk reduction is limited. What were the main findings? Successful interactions depended on personal, professional, organisational and systemic factors which either enhanced or inhibited relational quality, shared decision-making, mutual commitment, and nurses' confidence and capacity to address lifestyle risks. Targeted professional development and peer mentoring are needed to build proficient practice. Where and on whom will the research have impact? Understanding how general practice nurses support risk reduction can inform policy and identify training and support needs to advance their skills and role. Research exploring synergies between themes may illuminate this process.

RESUMO

AIMS: Low blood 25(OH)D level is associated with increased cardiovascular disease (CVD) risk. Additionally, individuals with prediabetes are at higher risk for CVD than individuals with normoglycemia. We investigated the effects of vitamin D supplementation on CVD outcomes in the vitamin D and type 2 diabetes (D2d) study, a large trial among adults with prediabetes. METHODS: 2423 participants were randomized to 4000 IU/day of vitamin D3 or placebo and followed for median 3.0 years for new-onset diabetes. In pre-specified secondary analyses, we examined the effect of vitamin D supplementation on composite Major Adverse Cardiovascular Events (MACE); expanded MACE (MACE + revascularization); atherosclerotic CVD (ASCVD) risk score; and individual CVD risk factors (blood pressure, lipids, high-sensitivity C-reactive protein). Cox models compared hazard ratios (HR) between the two groups on MACE and expanded MACE. RESULTS: Mean age was 60 years, 45 % were women, 13 % had history of CVD. Twenty-one participants assigned to vitamin D and 12 participants assigned to placebo met the MACE outcome (HR 1.81, 95%CI 0.89 to 3.69). There were 27 expanded MACE outcomes in each group (HR 1.02, 95%CI, 0.59 to 1.76). There were no significant differences between vitamin D and placebo in individual CVD risk factors, but change in ASCVD risk score favored the vitamin D group (-0.45 %, 95%CI -0.75 to -0.15). CONCLUSIONS: In people with prediabetes not selected for vitamin D insufficiency and with intermediate CVD risk, vitamin D supplementation did not decrease MACE but had a small favorable effect on ASCVD risk score. TRIAL REGISTRATION: D2d ClinicalTrials.gov number, NCT01942694, prospectively registered September 16, 2013.

RESUMO

Depending on personal and hereditary factors, each woman has a different risk of developing breast cancer, one of the leading causes of death for women. For women with a high-risk of breast cancer, their risk can be reduced by two main therapeutic approaches: 1) preventive treatments such as hormonal therapies (i.e., tamoxifen, raloxifene, exemestane); or 2) a risk reduction surgery (i.e., mastectomy). Existing national clinical guidelines either fail to incorporate or have limited use of the personal risk of developing breast cancer in their proposed risk reduction strategies. As a result, they do not provide enough resolution on the benefit-risk trade-off of an intervention policy as personal risk changes. In addressing this problem, we develop a discrete-time, finite-horizon Markov decision process (MDP) model with the objective of maximizing the patient's total expected quality-adjusted life years. We find several useful insights some of which contradict the existing national breast cancer risk reduction recommendations. For example, we find that mastectomy is the optimal choice for the border-line high-risk women who are between ages 22 and 38. Additionally, in contrast to the National Comprehensive Cancer Network recommendations, we find that exemestane is a plausible, in fact, the best, option for high-risk postmenopausal women.

RESUMO

PURPOSE: The Comprehensive Cancer Control Cancer Communication Mentorship Program ("Mentorship Program") was created by the George Washington University Cancer Center (GWCC) to provide technical assistance (TA) in implementing evidence-based cancer screening communication interventions and support networking for comprehensive cancer control (CCC) professionals. The Mentorship Program matched entry-to mid-level CCC professionals with health communication and/or CCC experts and offered monthly web-based discussions with academic researchers and practitioners who shared their knowledge and provided applied learning opportunities throughout mentees' project planning, implementation and evaluation. The program objective was for mentees to improve health communication skills and apply evidence-based knowledge to reduce the burden of cancer. METHODS: A mixed methods evaluation was conducted, including a qualitative description of each project and its outcomes as well as quantitative measures of satisfaction with the program and self-rated changes in competence. RESULTS: Mentees represented the following locations: New Jersey, Arkansas, Michigan, West Virginia, and Republic of Palau. Project topics ranged from increasing Human papillomavirus (HPV) vaccinations to increasing screening uptake for colorectal cancer, lung cancer, cervical cancer, and breast cancer. Evaluation results from pre- and post-program communication competency self-assessments and mid- and post-program surveys revealed that the Mentorship Program advanced personal and professional goals and improved public health communication skills. CONCLUSION: The Mentorship Program achieved its objectives for peer networking and offering expert TA in cancer prevention and control communication, offering a promising model for others involved in supporting implementation of evidence in practice.

RESUMO

The primary prevention of non-communicable diseases is one of the most challenging and exciting aspects of medicine and primary care this century. For cancer, it is an urgent matter in light of the increasing burden of the disease among younger people and the higher frequency of more aggressive forms of the disease for all ages. Most chronic disorders result from the influence of the environment on the expression of genes within an individual. The environment at-large encompasses lifestyle (including nutrition), and chemical/physical and social exposures. In cancer, the interaction between the (epi)genetic makeup of an individual and a multiplicity of environmental risk and protecting factors is considered key to disease onset. Thus, like for precision therapy developed for patients, personalized or precision prevention is envisioned for individuals at risk. Prevention means identifying people at higher risk and intervening to reduce the risk. It requires biological markers of risk and non-aggressive preventive actions for the individual, but it also involves acting on the environment and the community. Social scientists are considering micro (individual/family), meso (community), and macro (country population) levels of care to illustrate that problems and solutions exist on different scales. Ideally, the design of interventions in prevention should integrate all these levels. In this perspective article, using the example of breast cancer, we are discussing challenges and possible solutions for a multidisciplinary community of scientists, primary health care practitioners and citizens to develop a holistic approach of primary prevention, keeping in mind equitable access to care.
