RESUMO

This article reports the results of an ecological study of cancer incidence rates by state in the US for the period 2016-2020. The goals of this study were to determine the extent to which solar UVB doses reduced cancer risk compared to findings reported in 2006 for cancer mortality rates for the periods 1950-1969 and 1970-1794 as well as cancer incidence rates for the period 1998-2002 and to determine which factors were recently associated with cancer risk. The cancer data for non-Hispanic white (European American) men and women were obtained from the Centers for Disease Control and Prevention. Indices were obtained for solar UVB at the surface for July 1992, and alcohol consumption, diabetes, and obesity prevalence near the 2016-2020 period. Lung cancer incidence rates were also used in the analyses as a surrogate for smoking, diet, and air pollution. The cancers for which solar UVB is significantly associated with reduced incidence are bladder, brain (males), breast, corpus uteri, esophageal, gastric, non-Hodgkin's lymphoma, pancreatic, and renal cancer. Lung cancer was significantly associated with colorectal, laryngeal, and renal cancer. Diabetes was also significantly associated with breast, liver, and lung cancer. Obesity prevalence was significantly associated with breast, colorectal, and renal cancer. Alcohol consumption was associated with bladder and esophageal cancer. Thus, diet has become a very important driver of cancer incidence rates. The role of solar UVB in reducing the risk of cancer has been reduced due to people spending less time outdoors, wearing sunscreen that blocks UVB but not UVA radiation, and population increases in terms of overweight and obese individuals, which are associated with lower 25-hydroxyvitamin D concentrations and the generation of systemic inflammation, which is a risk factor for cancer. A dietary approach that would reduce the risk of diabetes, obesity, lung cancer, and, therefore, cancer, would be one based mostly on whole plants and restrictions on red and processed meats and ultraprocessed foods. Solar UVB exposure for a few minutes before applying sunscreen and taking vitamin D supplements would also help reduce the risk of cancer.

RESUMO

PURPOSE: This paper examines the subjective experience of medical interventions on intersex bodies to reduce cancer risk. METHODS: Twenty-five individuals with intersex variations took part in semi-structured interviews, analysed through thematic discourse analysis. RESULTS: Intersex bodies were positioned as inherently sick and in need of modification, with cancer risk legitimating surgical and hormonal intervention. This resulted in embodied shame, with negative impacts on fertility and sexual wellbeing. However, many participants resisted discourses of bio-pathologisation and embraced intersex status. Some medical interventions, such as HRT, were perceived to have increased the risk of cancer. Absence of informed consent, and lack of information about intersex status and the consequences of medical intervention, was positioned as a human rights violation. This was compounded by ongoing medical mismanagement, including health care professional lack of understanding of intersex variations, and the objectification or stigmatization of intersex people within healthcare. The consequence was non-disclosure of intersex status in health contexts and lack of trust in health care professionals. CONCLUSIONS: The legitimacy of poorly-evidenced cancer risk discourses to justify medical intervention on intersex bodies needs to be challenged. Healthcare practitioners need to be provided with education and training about cultural safety practices for working with intersex people.

RESUMO

The Wnt/ß-Catenin pathway (Wnt/ß-CatP) is implicated in accelerating carcinogenesis and cancer progression, contributing to increased morbidity and treatment resistance. Even though it holds promise as a focus for cancer treatment, its intricate nature and diverse physiological effects pose significant challenges. Recent years have witnessed significant advancements in this domain, with numerous natural products demonstrating promising preclinical anti-tumor effects and identified as inhibitors of the Wnt/ß-CatP through various upstream and downstream mechanisms. This study provides a comprehensive overview of the current landscape of Wnt/ß-Cat-targeted cancer therapy, examining the impact of natural products on Wnt/ß-Cat signaling in both cancer prevention and therapeutic contexts. A comprehensive search was conducted on scientific databases like SciFinder, PubMed, and Google Scholar to retrieve relevant literature on Wnt-signaling, natural products, ß-Catenin (ß-Cat), and cancer from 2020 to January 2024. As per the analysis of the relevant reference within the specified period, it has been noted that a total of 58 phytoconstituents, predominantly phenolics, followed by triterpenoids and several other classes, along with a limited number of plant extracts, have exhibited activity targeting the Wnt/ß-CatP. Most ß-Cat regulating modulators restrict cancer cell development by suppressing ß-Cat expression, facilitating proteasomal degradation, and inhibiting nuclear translocation. Multiple approaches have been devised to block the activity of ß-Cat in cancer therapy, a key factor in cancer progression, leading to the discovery of various Wnt/ß-CatP regulators. However, their exploration remains limited, necessitating further research using clinical models for potential clinical use in cancer prevention and therapeutics.

RESUMO

This Paper argues that to protect at-risk communities - and all Americans - from the deadly effects of environmental racism, Congress must pass the Environmental Justice for All Act. The Act is intended to "restore, reaffirm, and reconcile environmental justice and civil rights." It does so by restoring an individual's right to sue in federal court for discrimination based on race, ethnicity, or national origin regardless of intent under the Civil Rights Act of 1964, strengthening the National Environmental Policy Act, and providing economic incentives focused on environmental justice.

RESUMO

Cancer education programs are regularly conducted in schools in Japan. Previous reports on their effectiveness were based on surveys conducted several months after the education. We aimed to evaluate whether cancer education for children influenced their behavioral changes in adulthood. We targeted schools where the Japan Cancer Society has conducted the programs since 2011 and the program participants are older than 21 years currently. Invitations were sent to the participants and controls who graduated one year before or after the participants, and answers were obtained using an online questionnaire. Data were collected on the willingness to undergo cancer screening, sociodemographic characteristics, healthy behaviors, and health literacy. We compared the data from the program participants with those from controls. We requested cooperation from 13 schools; however, only one agreed. The common reason for refusal was privacy concerns. In the all-boys participating school in Tokyo, there was no significant difference in background information between the cancer education (38 participants) and control (55 participants) groups. Multiple linear regression showed that healthcare or welfare education background (ß = 0.25, p = 0.01) and health literacy (ß = 0.24, p = 0.02) were significant predictors of cancer screening intention, while the presence of cancer education (p = 0.25) was not. Despite severe selection bias, this is the first study to examine the long-term impacts of cancer education. We found no significant impacts on the measured outcome. However, the educational content at that time differed from that of today, and the program's efficacy should not be negated.

RESUMO

BACKGROUND: Clinical practice guidelines (CPGs) synthesize high-quality information to support evidence-based clinical practice. In primary care, numerous CPGs must be integrated to address the needs of patients with multiple risks and conditions. The BETTER program aims to improve prevention and screening for cancer and chronic disease in primary care by synthesizing CPGs into integrated, actionable recommendations. We describe the process used to harmonize high-quality cancer and chronic disease prevention and screening (CCDPS) CPGs to update the BETTER program. METHODS: A review of CPG databases, repositories, and grey literature was conducted to identify international and Canadian (national and provincial) CPGs for CCDPS in adults 40-69 years of age across 19 topic areas: cancers, cardiovascular disease, chronic obstructive pulmonary disease, diabetes, hepatitis C, obesity, osteoporosis, depression, and associated risk factors (i.e., diet, physical activity, alcohol, cannabis, drug, tobacco, and vaping/e-cigarette use). CPGs published in English between 2016 and 2021, applicable to adults, and containing CCDPS recommendations were included. Guideline quality was assessed using the Appraisal of Guidelines for Research and Evaluation (AGREE) II tool and a three-step process involving patients, health policy, content experts, primary care providers, and researchers was used to identify and synthesize recommendations. RESULTS: We identified 51 international and Canadian CPGs and 22 guidelines developed by provincial organizations that provided relevant CCDPS recommendations. Clinical recommendations were extracted and reviewed for inclusion using the following criteria: 1) pertinence to primary prevention and screening, 2) relevance to adults ages 40-69, and 3) applicability to diverse primary care settings. Recommendations were synthesized and integrated into the BETTER toolkit alongside resources to support shared decision-making and care paths for the BETTER program. CONCLUSIONS: Comprehensive care requires the ability to address a person's overall health. An approach to identify high-quality clinical guidance to comprehensively address CCDPS is described. The process used to synthesize and harmonize implementable clinical recommendations may be useful to others wanting to integrate evidence across broad content areas to provide comprehensive care. The BETTER toolkit provides resources that clearly and succinctly present a breadth of clinical evidence that providers can use to assist with implementing CCDPS guidance in primary care.

RESUMO

INTRODUCTION: Cancer Health literacy (CHL) is the health literacy related to cancer knowledge, prevention, treatment, screening, and access to services. It is an important indicator of people's adherence to screening and preventive measures, which helps to reduce the incidence and prevalence of cancer. The study assessed the CHL level and its association with relevant socio-demographic characteristics and sources of information among primary health care patients and visitors in the United Arab Emirates (UAE). METHODS: A cross-sectional study recruited survey participants who consented to respond to an interviewer-administered questionnaire. The assessment of CHL was done by using 15 questions. CHL level was measured as a median score and also categorized as poor/inadequate, moderate, good/excellent. Nominal logistic regression was used to analyze the relationship between CHL categories and participants' sociodemographic characteristics and CHL sources of information. RESULTS: Of the total 492 participants, 45.5% were young adults (30-39 years old), 32.9% were males, and 70.8% were UAE nationals. The overall median CHL score was 8.0 (IQR = 5.0-10). 33.7% of the participants had a poor/inadequate level of CHL, 49.6% had a moderate level and 16.7% had a good to excellent level of CHL. 76.9% of the participants knew the importance of early cancer screening tests, 72.7% acknowledged the metastatic capacity of cancer, and the protective factors of cancer, especially, in colon cancer (71.7%). A high proportion of participants received health information about cancer via the internet (50.7%), television (45.3%), social media (40.2%), and doctors (43.6%). Nationality other than UAE (aOR = 1.62, 95% CI = 1.03-2.56, P = .038), having university education (aOR = 2.20, 95% CI = 1.21-3.99, P = .010) compared to those with lower than high school, and having a family history of cancer (aOR = 2.42, 95% CI = 1.33-4.41, P = .004) were positively associated with CHL. Older age (aOR = .36, 95% CI = .17-.75, P = .007 for 50-59 years, and aOR = .29, 95% CI = .11-.82, P = .019) for 60-69 years, higher-income (aOR = .57, 95% CI = .33-.99, P = .047 for 10,000-19,999 AED; aOR = .53, 95% CI = .33-.88, P = .013 for ≥20,000) compared with those earning <10,000 AED were negatively associated with CHL. CONCLUSIONS: CHL among the resident UAE population was moderately adequate, therefore implementation of awareness campaigns seems to be warranted. Moreover, evaluation research targeting the CHL impact on cancer prevention practices and screening is also advocated.

RESUMO

Introduction: A better understanding of how to promote disease mitigation and prevention behaviors among vulnerable populations, such as cancer survivors, is needed. This study aimed to determine patterns of and factors associated with COVID-19-related preventive behaviors among cancer survivors and assess whether the COVID-19 preventive behaviors of cancer survivors differ from the general population. Methods: In June 2020, an online survey of adults (N = 897) assessed predictors of COVID-19-related preventive behaviors, including socio-demographics, COVID-19 beliefs and perceptions (Health Belief Model [HBM] variables), and cancer statuses (cancer survivors currently in treatment, cancer survivors not currently in treatment, and individuals with no history of cancer). An average score of respondent engagement in eight preventive behaviors was calculated. Differences in HBM variables and preventive behaviors by cancer status were assessed using ANCOVAs. Hierarchical multiple regression analyzed associations among socio-demographics, HBM constructs, cancer statuses, and engagement in COVID-19 preventive behaviors. Results: Participants reported engaging in 3.5 (SD = 0.6) preventive behaviors. Cancer survivors not in treatment engaged in preventive behaviors significantly less than the comparison group. In the final adjusted model, after adding COVID-19 beliefs and perceptions, cancer status was no longer significant. All HBM constructs except perceived susceptibility were significant predictors of preventive behaviors. Conclusions: COVID-19 beliefs and perceptions were more robust predictors preventive behaviors than cancer status. Nonetheless, public health organizations and practitioners should communicate the risk and severity of infection among cancer survivors and emphasize the need to engage in protective behaviors for COVID-19 and other infectious diseases with this vulnerable population.

RESUMO

BACKGROUND: Digital technologies have positively impacted the availability and usability of clinical algorithms through the advancement in mobile health. Therefore, this study aimed to determine if a web-based algorithm designed to support the decision-making process of cancer care providers (CCPs) differentially impacted their self-reported self-efficacy and practices for providing smoking prevention and cessation services in Peru and Colombia. METHODS: A simple decision-making tree algorithm was built in REDCap using information from an extensive review of the currently available smoking prevention and cessation resources. We employed a pre-post study design with a mixed-methods approach among 53 CCPs in Peru and Colombia for pilot-testing the web-based algorithm during a 3-month period. Wilcoxon signed-rank test was used to compare the CCPs' self-efficacy and practices before and after using the web-based algorithm. The usability of the web-based algorithm was quantitatively measured with the system usability scale (SUS), as well as qualitatively through the analysis of four focus groups conducted among the participating CCPs. RESULTS: The pre-post assessments indicated that the CCPs significantly improved their self-efficacy and practices toward smoking prevention and cessation services after using the web-based algorithm. The overall average SUS score obtained among study participants was 82.9 (± 9.33) [Peru 81.5; Colombia 84.1]. After completing the qualitative analysis of the focus groups transcripts, four themes emerged: limited resources currently available for smoking prevention and cessation in oncology settings, merits of the web-based algorithm, challenges with the web-based algorithm, and suggestions for improving this web-based decision-making tool. CONCLUSION: The web-based algorithm showed high usability and was well-received by the CCPs in Colombia and Peru, promoting a preliminary improvement in their smoking prevention and cessation self-efficacy and practices.

RESUMO

OBJECTIVE: Characterize experiences with cancer and perceptions of the preventable cancer burden attributable to diet among firefighters. DESIGN: A cross-sectional survey was distributed to assess cancer history and perceptions of cancer. SETTING: US. PARTICIPANTS: US-based firefighters. MAIN OUTCOME MEASURE(S): History of cancer, perceptions of cancer, and perceptions of diet as a means to prevent cancer. ANALYSIS: Descriptive statistics and use of the Behaviour Change Technique Taxonomy v1 (BCTTv1) to evaluate qualitative responses. RESULTS: A total of 471 firefighters participated. Nearly half (48.4%) voiced they strongly agreed that they were at risk for cancer, whereas 44.6% agreed that changing diet could decrease cancer risk. The most common BCTTv1 codes focused on types of education, including "Instruction on how to perform the behavior" (45.1%, n = 189), followed by those centered on behavior execution (eg, "Action planning" [24.8%, n = 104]). Qualitatively, many were concerned about misinformation. CONCLUSIONS AND IMPLICATIONS: Firefighters acknowledge the role of diet in cancer risk and have a desire for knowledge and behavioral support (eg, goal setting) that includes an emphasis on evidence and tackling misinformation. This information should serve as the basis of future interventions that target diet.

RESUMO

The incidence of distant metastases is associated with most cancer-related mortalities. Extracellular vesicles (EVs), secreted from tumors and cancer-associated fibroblasts, are involved in the metastatic process mediating their organotropism through their involvement in the pre-metastatic niche formation. We have been developing suicide gene therapy mediated by EVs secreted from mesenchymal stem/ stromal cells, tumor cells, and cancer-associated fibroblasts. Suicide gene EVs conjugated with prodrug are tumor tropic, penetrate tumor cells, and kill them by intracellular conversion of nontoxic prodrug to an efficient anti-cancer drug. Here, we discuss findings regarding the possibility of using suicide gene EVs as a novel therapeutic approach for metastases, via pre-metastatic niche modification. The suicide gene EVs provide a future perspective for metastasis prevention.

RESUMO

For over a decade, immunotherapy has been transforming cancer treatment and prognosis. Tumor therapeutic vaccines trigger new immune responses and enhance existing immunity to more effectively combat cancer. These vaccines aim to curb the established disease or prevent recurrence, unlike conventional preventive vaccines. There are four categories of therapeutic vaccines: cellular, viral/bacterial, peptide, and nucleic acid, each with its own benefits and challenges. Advances in the understanding of anti-tumor immunity and advanced technologies such as mRNA vaccines support the development of this new treatment option. Currently in clinical trials, they could lead to promising and personalised anti-cancer therapies.


Depuis plus d'une décennie, l'immunothérapie améliore le traitement et le pronostic des patients atteints de cancer. Les vaccins thérapeutiques tumoraux activent de nouvelles réponses immunitaires et amplifient l'immunité existante pour combattre le cancer plus efficacement. Ces vaccins visent à freiner la maladie établie ou à éviter les récidives, à la différence des vaccins préventifs classiques. Il existe quatre catégories de vaccins thérapeutiques : cellulaire, viral/bactérien, peptidique et à acide nucléique, chacun avec des bénéfices et des défis spécifiques. Les avancées dans la compréhension de l'immunité antitumorale et dans les technologies de pointe, comme les vaccins à ARNm, favorisent le développement de cette nouvelle option de traitement. Actuellement en essais cliniques, ils pourraient aboutir à des thérapies anticancéreuses prometteuses et personnalisées.

RESUMO

CONTEXT: Cardiovascular diseases (CVDs) and cancer are the two main leading causes of death and disability worldwide. Suboptimal diet, poor in vegetables, fruits, legumes and whole grain, and rich in processed and red meat, refined grains, and added sugars, is a primary modifiable risk factor. Based on health, economic and ethical concerns, plant-based diets have progressively widespread worldwide. OBJECTIVE: This umbrella review aims at assessing the impact of animal-free and animal-products-free diets (A/APFDs) on the risk factors associated with the development of cardiometabolic diseases, cancer and their related mortalities. DATA SOURCES: PubMed and Scopus were searched for reviews, systematic reviews, and meta-analyses published from 1st January 2000 to 31st June 2023, written in English and involving human subjects of all ages. Primary studies and reviews/meta-analyses based on interventional trials which used A/APFDs as a therapy for people with metabolic diseases were excluded. DATA EXTRACTION: The umbrella review approach was applied for data extraction and analysis. The revised AMSTAR-R 11-item tool was applied to assess the quality of reviews/meta-analyses. RESULTS: Overall, vegetarian and vegan diets are significantly associated with better lipid profile, glycemic control, body weight/BMI, inflammation, and lower risk of ischemic heart disease and cancer. Vegetarian diet is also associated with lower mortality from CVDs. On the other hand, no difference in the risk of developing gestational diabetes and hypertension were reported in pregnant women following vegetarian diets. Study quality was average. A key limitation is represented by the high heterogeneity of the study population in terms of sample size, demography, geographical origin, dietary patterns, and other lifestyle confounders. CONCLUSIONS: Plant-based diets appear beneficial in reducing cardiometabolic risk factors, as well as CVDs, cancer risk and mortality. However, caution should be paid before broadly suggesting the adoption of A/AFPDs since the strength-of-evidence of study results is significantly limited by the large study heterogeneity alongside the potential risks associated with potentially restrictive regimens.

RESUMO

PURPOSE: Promoting cancer preventive behaviors among adolescents, especially those from lower socioeconomic backgrounds, is crucial due to the significant impact of health behaviors in adolescence on disease risk in adulthood. With India witnessing a rise in cancer incidence and mortality, adolescence becomes a pivotal stage for establishing healthy habits, emphasizing the need for early cancer prevention efforts. METHODS: This cross-sectional study used survey data from 2242 adolescents attending public schools of Mumbai, India. Multiple logistic regression was conducted to determine the associations between cancer preventive behaviors and: (1) the individual and social determinants of health, and (2) media exposure. FINDINGS: Merely 21.5% of the adolescents ate fruits and vegetables daily, 50% of the adolescents exercised 3 or more times a week, and 20% of the adolescents admitted having used tobacco and/or supari. Girls were found to have lower odds of exercising, as well as using tobacco and/or supari. Wealth and father's education were positively associated with all 3 cancer preventive behaviors. Media exposure was negatively associated, with television exposure linked to reduced fruits and vegetables consumption, while movies and social media exposure were associated with increased tobacco and/or supari use. INTERPRETATION: Our findings suggest that individual and social determinants of health and media exposure can influence cancer preventive health behaviors in low socio-economic status (SES) adolescents. Efforts to increase awareness to promote cancer preventive behaviors among the adolescents, particularly low SES adolescents, a population more vulnerable to poor health outcomes, is critical.


This study investigates factors that can influence cancer preventive behaviors among low socioeconomic status (SES) adolescents, focusing on dietary habits, physical activity, and avoidance of tobacco and areca nut. Our study gathered data from an underrepresented population of India, which is more vulnerable to poor health outcomes and have less access to health care. Our findings can alert public health officials, policy makers and non-governmental organizations to target this population and customize their intervention strategies to promote health and prevent cancer.

RESUMO

Increasingly, research demonstrates economic benefits of tobacco cessation in cancer care, as seen in a new study by Kypriotakis and colleagues of the MD Anderson cessation program, demonstrating median health care cost savings of $1,095 per patient over 3 months. While the cost-effectiveness of tobacco cessation programs from a hospital perspective is important, implementation decisions in a predominantly fee-for-service system, such as in the United States, too often insufficiently value this outcome. Economic barriers, stakeholder disincentives, and payment models all impact program implementation. Combining economic evaluation with implementation research, including assessment of return-on-investment, may enhance sustainability and inform decision-making in cancer care settings. See related article by Kypriotakis et al., p. 217.

Peptide antigens derived from tumors have been observed to elicit protective immune responses, categorized as either tumor-associated antigens (TAAs) or tumor-specific antigens (TSAs). Subunit cancer vaccines incorporating these antigens have shown promise in inducing protective immune responses, leading to cancer prevention or eradication. Over recent years, peptide-based cancer vaccines have gained popularity as a treatment modality and are often combined with other forms of cancer therapy. Several clinical trials have explored the safety and efficacy of peptide-based cancer vaccines, with promising outcomes. Advancements in techniques such as whole-exome sequencing, next-generation sequencing, and in silico methods have facilitated the identification of antigens, making it increasingly feasible. Furthermore, the development of novel delivery methods and a deeper understanding of tumor immune evasion mechanisms have heightened the interest in these vaccines among researchers. This article provides an overview of novel insights regarding advancements in the field of peptide-based vaccines as a promising therapeutic avenue for cancer treatment. It summarizes existing computational methods for tumor neoantigen prediction, ongoing clinical trials involving peptide-based cancer vaccines, and recent studies on human vaccination experiments.

RESUMO

The Mediterranean diet, renowned for its health benefits, especially in reducing cardiovascular risks and protecting against diseases like diabetes and cancer, emphasizes virgin olive oil as a key contributor to these advantages. Despite being a minor fraction, the phenolic compounds in olive oil significantly contribute to its bioactive effects. This review examines the bioactive properties of hydroxytyrosol and related molecules, including naturally occurring compounds (-)-oleocanthal and (-)-oleacein, as well as semisynthetic derivatives like hydroxytyrosyl esters and alkyl ethers. (-)-Oleocanthal and (-)-oleacein show promising anti-tumor and anti-inflammatory properties, which are particularly underexplored in the case of (-)-oleacein. Additionally, hydroxytyrosyl esters exhibit similar effectiveness to hydroxytyrosol, while certain alkyl ethers surpass their precursor's properties. Remarkably, the emerging research field of the effects of phenolic molecules related to virgin olive oil on cell autophagy presents significant opportunities for underscoring the anti-cancer and neuroprotective properties of these molecules. Furthermore, promising clinical data from studies on hydroxytyrosol, (-)-oleacein, and (-)-oleocanthal urge further investigation and support the initiation of clinical trials with semisynthetic hydroxytyrosol derivatives. This review provides valuable insights into the potential applications of olive oil-derived phenolics in preventing and managing diseases associated with cancer, angiogenesis, and atherosclerosis.
