Lay Awareness of the Relationship between Age and Cancer Risk

Benefit-Risk Trade-offs and Patient Preferences for Therapy Selection in Ulcerative Colitis: a Multicountry Preference Study

BACKGROUND

To help navigate the complex treatment landscape of ulcerative colitis (UC), we quantified the benefit-risk trade-offs that patients were willing to make when choosing treatment.

METHODS

Patients completed an online discrete choice experiment. Eligible patients had a UC diagnosis for ≥6 months, were aged ≥18 years, and resided in France, Germany, Italy, Spain, or the UK. Patients chose between 2 hypothetical treatments set up to ensure trade-offs were made. Clinical trial data, literature review, and patient interviews identified treatment attributes. Relative attribute importance (RAI) scores and maximum acceptable risks were generated. A patient-centric benefit-risk assessment of 200 mg of filgotinib was conducted as an example to show how measured trade-offs can be used.

RESULTS

Overall, 631 patients participated; patients had a mean age of 42.2 years and were predominantly male (75.3%). Achieving and maintaining clinical remission was the most important factor for patients (RAI 32.4%); to achieve this, patients were willing to accept slightly higher risks of blood clots, serious infections, and malignancies compared with lower risk treatment profiles. Patients also valued the convenience of oral treatments, avoiding steroids, and the ability to attend school/work. The patient-centric benefit-risk assessment suggested patients are significantly more likely to prefer Janus kinase 1 preferential inhibitor filgotinib over placebo.

CONCLUSIONS

Achieving clinical remission was the highest treatment priority for patients. To attain this, patients were willing to accept some slightly higher risk treatment profiles. Patient choices in the benefit-risk assessment suggested patients were significantly more likely to prefer filgotinib over placebo.

Prevalence and predictors of colorectal cancer screening in the United States: evidence from the HINTS database 2018 to 2020

BACKGROUND

The incidence of colorectal cancer (CRC) and CRC-related mortality among young adults (< 50 years) has been on the rise. The American Cancer Society (ACS) reduced the CRC screening age to 45 in 2018. Few studies have examined the barriers to CRC screening among young adults.

METHODS

Analyses were conducted using data from 7,505 adults aged 45-75 years who completed the 2018 to 2020 Health Information National Trends Survey. We examined the sociodemographic characteristics associated with CRC screening overall and by age group using separate multivariable logistic regression models.

RESULTS

76% of eligible adults had received screening for CRC. Increasing age, Black racial group [OR 1.45; 95% CI (1.07, 1.97)], having some college experience, a college degree or higher [OR 1.69; 95% CI (1.24, 2.29)], health insurance coverage [OR 4.48; 95% CI (2.96, 6.76)], primary care provider access [OR 2.48; 95% CI (1.91, 3.22)] and presence of a comorbid illness [OR 1.39; 95% CI (1.12, 1.73)] were independent predictors of CRC screening. Current smokers were less likely to undergo CRC screening [OR 0.59; 95% CI (0.40, 0.87)]. Among adults aged 50-64 years, being of Hispanic origin [OR 0.60; 95% CI (0.39, 0.92)] was associated with a lower likelihood of CRC screening.

CONCLUSION

CRC screening rates among adults 45-49 years are low but are increasing steadily. Odds of CRC screening among Blacks is high which is encouraging while the odds among current smokers is low and concerning given their increased risk of developing CRC.

Using the Multidimensional Health Locus of Control Scale Form C to Investigate Health Beliefs About Bladder Cancer Prevention and Treatment Among Male Patients: Cross-Sectional Study

BACKGROUND

Bladder cancer is a leading cause of death among Chinese male populations in recent years. The health locus of control construct can mediate health status and outcomes, and it has proven helpful in predicting and explaining specific health-related behaviors. However, it has never been used to investigate health beliefs about bladder cancer prevention and treatment.

OBJECTIVE

This study aimed to classify male patients into different latent groups according to their beliefs about bladder cancer prevention and treatment and to identify associated factors to provide implications for the delivery of tailored education and interventions and the administration of targeted prevention and treatment.

METHODS

First, we designed a four-section questionnaire to solicit data: section 1-age, gender, and education; section 2-the communicative subscale of the All Aspects of Health Literacy Scale; section 3-the eHealth Literacy Scale; and section 4-health beliefs about bladder cancer prevention and treatment measured by the Multidimensional Health Locus of Control Scale Form C. We hypothesized that the participants' health beliefs about bladder cancer prevention and treatment measured in section 4 could be closely associated with information collected through sections 1 to 3. We recruited 718 Chinese male patients from Qilu Hospital of Shandong University, China, and invited them to participate in a web-based questionnaire survey. Finally, we used latent class analysis to identify subgroups of men based on their categorical responses to the items on the Multidimensional Health Locus of Control Scale Form C and ascertained factors contributing to the low self-efficacy group identified.

RESULTS

We identified 2 subgroups defined as low and moderate self-efficacy groups representing 75.8% (544/718) and 24.2% (174/718) of the total sample, respectively. Men in the low self-efficacy cluster (cluster 1: 544/718, 75.8%) were less likely to believe in their own capability or doctors' advice to achieve optimal outcomes in bladder cancer prevention and treatment. Men in the moderate self-efficacy cluster (cluster 2: 174/718, 24.2%) had distinct psychological traits. They had stronger beliefs in their own capability to manage their health with regard to bladder cancer prevention and treatment and moderate to high levels of trust in health and medical professionals and their advice to achieve better prevention and treatment outcomes. Four factors contributing to low self-efficacy were identified, including limited education (Year 6 to Year 12), aged ≥44 years, limited communicative health literacy, and limited digital health literacy.

CONCLUSIONS

This was the first study investigating beliefs about bladder cancer prevention and treatment among Chinese male patients. Given that bladder cancer represents a leading cause of death among Chinese male populations in recent years, the low self-efficacy cluster and associated contributing factors identified in this study can provide implications for clinical practice, health education, medical research, and health policy-making.

Risk perception of non-communicable diseases: A systematic review on its assessment and associated factors

BACKGROUND

The burden of non-communicable diseases (NCDs) is increasing. Risk perception of NCDs is an important factor towards the uptake of preventive health interventions. There are various questionnaires assessing risk perception of NCDs, but no internationally standardized questionnaire has been available. Identification of factors associated with risk perception of NCDs may facilitate the development of targeted interventions. This systematic review aims to identify available questionnaire assessing risk perception of NCDs and the factors associated with risk perception of NCDs.

METHODS

The reporting of this systematic review is in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We carried out a literature search through three databases (Scopus, PubMed, Web of Science) and targeted original article published in English between 2012 and 2021. Quality appraisal of the eligible articles was conducted using the Mixed Methods Appraisal Tool. Findings were synthesized using content analysis.

RESULTS

A total of 86 studies were included. We found a variety of questionnaires assessing risk perception of NCDs, with many differences in their development, domains, items and validity. We also identified several personal, sociopsychological and structural factors associated with risk perception of NCDs.

LIMITATIONS

Most of the included studies were of cross-sectional design, and therefore the quality of evidence was considered low and exhibit a high risk of bias. The role of publication bias within this systematic review should be acknowledged as we did not include grey literature. Additionally, language bias must be considered as we only included English-language publications.

CONCLUSION

Further development and testing of available questionnaire is warranted to ensure their robustness and validity in measuring risk perception of NCDs. All the identified factors deserve further exploration in longitudinal and experimental studies.

The epidemiology of multiple primary cancers in Belgium (2004-2017): Incidence, proportion, risk, stage and impact on relative survival estimates

BACKGROUND

As both life expectancy and cancer survival improve, the incidence of multiple primary cancer has augmented and is expected to further increase. This study describes for the first time the epidemiology of multiple invasive tumours in Belgium.

METHODS

This nationwide study, based on all cancers diagnosed between 2004 and 2017 in Belgium, describes the proportion of multiple primary cancer, its evolution over time, the impact of inclusion or exclusion of multiple primary cancer on relative survival estimates, the risk of developing a second primary cancer, and the difference in stage between first and second primary cancer for the same patient.

RESULTS

The proportion of multiple primary cancer increases with age, varies across cancer sites (from 4% for testis cancer to 22.8% for oesophageal cancer), is higher in men than in women, and has linearly increased over time. The inclusion of multiple primary cancer resulted in smaller 5-year relative survival and this impact is more pronounced in cancer sites with high relative survival. Patients with a first primary cancer have an increased risk to develop a new primary cancer compared to the population without a previous cancer history (1.27 and 1.59 times higher in men and women, respectively) and this risk depends on cancer site. Second primary cancers are associated with more advanced stages and more unknown stages than the corresponding first cancer diagnosis.

CONCLUSIONS

This study describes multiple primary cancer according to several measures (proportion, standardised incidence ratio for an second primary cancer, impact of multiple primary cancer on relative survival and differences according to stage) for the first time in Belgium. The results are based on data of a population-based cancer registry with a relatively recent onset (2004).

Disparities in stage at diagnosis for liver cancer in China

Background

The stage at diagnosis is a major factor in making treatment strategies and cancer control policies. However, the stage distribution for liver cancer in China was not well studied. In this multi-center hospital-based study, we aimed to identify the distribution and factors associated with stage at diagnosis for liver cancer in China.

Methods

We included patients diagnosed with primary liver cancer in 13 hospitals of 10 provinces covering various geographic and socioeconomic populations during 2016-2017 in China. The stage distribution overall, and by sex and age at diagnosis were analyzed. We used logistic regression to identify the factors associated with stage III-IV disease. We further compared these estimates with data from the USA.

Results

We included 2,991 patients with known stage at diagnosis in China. The proportion of patients diagnosed with stage I, II, III, and IV was 17.5%, 25.6%, 29.3%, and 27.6%, respectively. The proportion of stage III-IV cases was higher in women [65.1% vs 54.9%, adjusted odds ratio (OR) = 1.5, 95% CI: 1.2, 1.8] and those ≥ 60 years (61.6% vs 52.8%, OR = 1.4, 95% CI: 1.2, 1.6). We found an increased risk of stage III-IV among drinkers and those without a family history of cancer. Compared to the USA, our study population had a substantially higher proportion of stage III-IV cases (56.9% vs 45.6%).

Conclusion

The disparities in liver cancer stage at diagnosis among different populations within China, and between China and the USA, imply the necessity for improving cancer awareness and early detection for liver cancer in China.

[Statutory skin cancer screening in Germany : Motivation and motives for participation versus nonparticipation]

BACKGROUND

In 2008, statutory skin cancer screening (sSCS) was introduced in Germany for people aged ≥ 35 years with statutory health insurance (SHI). The aim is to diagnose malignant skin lesions at an early stage, reduce mortality and improve morbidity and quality of life. Although sSCS was introduced more than a decade ago, only a part of the public is aware of it.

OBJECTIVES

What are the reasons for the low participation rate in sSCS in the eligible population?

MATERIALS AND METHODS

In computer-assisted phone interviews with a representative population sample of N = 1015 persons aged ≥ 18 years with SHI attitude towards skin cancer, rate of use of sSCS and reasons for nonparticipation were surveyed in January 2019. Parts of the data were compared with previous surveys from 2011, 2013 and 2015.

RESULTS

Among the 1015 participants 40% were concerned about skin cancer (2011: 45%; 2013: 51%; 2015: 46%). Of the respondents 75.4% were authorised to use sSCS. Of these 52.6% had never participated in sSCS before. However, participation increased with age. Further, the nonparticipation rate for those with a high school-leaving certificate (45%) was significantly lower than for those with a lower schooling level (58%). The option for sSCS was unknown to 35% of nonparticipants. As a reason for nonparticipation 20% mentioned a lack of time, while 58% saw no need for it because they felt healthy. In general, 91% of all respondents considered early preventive examinations to be useful and 66% had already taken part in other preventive examinations.

CONCLUSIONS

The low participation rate of about 50% in sSCS and the decreasing concern about skin cancer suggest that further education of the general population about the relevance of skin cancer with a focus on risk groups is necessary.

Comprehensive genomic profile of cholangiocarcinomas in China

Cholangiocarcinoma (CCA) is a primary malignancy, which is often diagnosed as locally advanced or metastatic. Previous studies have revealed genomic characteristics of CCA in Western patients, however comprehensive genomic features of CCA in Chinese patients have not been well understood. To explore the specific genomic characteristics of Chinese patients with CCA, a total of 66 patients with CCA, including 44 intrahepatic CCA (iCCA) and 22 extrahepatic CCA (exCCA) cases, were studied. The most commonly altered genes in CCAs were TP53 (62.12%, 41/66), KRAS (36.36%, 24/66), SMAD4 (24.24%, 16/66), TERT (21.21%, 14/66), ARID1A (19.70%, 13/66), CDKN2A (19.70%, 13/66), KMT2C (9.09%, 6/66) and RBM10 (9.09%, 6/66), ERBB2 (7.58%, 5/66) and BRAF (7.58%, 5/66). Many gene mutations, including STK11, CCND1 and FGF19, were only found in iCCA. RBM10 mutations were found to be significantly higher in exCCA. The gene mutations of neurofibromin 1, STK11, CCND1 and FBXW7 specifically occurred in males, whereas gene mutations of ERBB2, AXIN2 and CREBBP specifically occurred in females. ERBB2 mutations were significantly associated with the sex of patients with CCA. Mutations in PIK3CA, FGFR2 and ZNF750 were significantly associated with the age of patients with CCA and TERT mutations were significantly associated with tumor differentiation. Alterations in KMT2C, PBRM1, AXIN2, MAGI2, BRCA2 and SPTA1 were associated with tumor mutational burden. The findings of the present study suggest that targeted sequencing, using next-generation sequencing technology, provides comprehensive and accurate information on genomic alterations, which will provide novel potential biomarkers for the diagnosis of CCA and may guide precise therapeutic strategies for Chinese patients with CCA.

Cancer Knowledge Among Mexican Immigrant Farmworkers in North Carolina

Latino farmworkers are exposed to a number of carcinogens in the workplace. Cancer survival rates for Latinos are below average. This paper describes Mexican immigrant farmworkers' knowledge of colorectal, breast, and testicular cancer, and compares farmworkers' cancer knowledge to that of other Mexican immigrants. Survey interviews for this study were conducted with 100 farmworkers and 100 non-farmworkers in 2015 in North Carolina as part of an ongoing community-based participatory research project. We found low to moderate levels of knowledge about colorectal, breast, and testicular cancer among farmworkers. Compared to non-farmworkers, farmworkers had similar levels of knowledge about breast and testicular cancer, but slightly lower knowledge about colorectal cancer (p = 0.0087). Few studies have used quantitative methods to assess farmworkers' knowledge of specific types of cancer. Our results demonstrate a need for increased dissemination of existing cancer education programs and further research to develop additional educational tools.

CancerClock: A DNA Methylation Age Predictor to Identify and Characterize Aging Clock in Pan-Cancer

Many biological indicators related to chronological age have been proposed. Recent studies found that epigenetic clock or DNA methylation age is highly correlated with chronological age. In particular, a significant difference between DNA methylation age (m-age) and chronological age was observed in cancers. However, the prediction and characterization of m-age in pan-cancer remains an explored area. In this study, 1,631 age-related methylation sites in normal tissues were discovered and analyzed. A comprehensive computational model named CancerClock was constructed to predict the m-age for normal samples based on methylation levels of the extracted methylation sites. LASSO linear regression model was used to screen and train the CancerClock model in normal tissues. The accuracy of CancerClock has proved to be 81%, and the correlation value between chronological age and m-age was 0.939 (P < 0.01). Next, CancerClock was used to evaluate the difference between m-age and chronological age for 33 cancer types from TCGA. There were significant differences between predicted m-age and chronological age in large number of cancer samples. These cancer samples were defined as “age-related cancer samples” and they have some differential methylation sites. The differences between predicted m-age and chronological age may contribute to cancer development. Some of these differential methylation sites were associated with cancer survival. CancerClock provided assistance in estimating the m-age in normal and cancer samples. The changes between m-age and chronological age may improve the diagnosis and prognosis of cancers.

Heart disease versus cancer: understanding perceptions of population prevalence and personal risk

Although the gap is narrowing, Americans are more likely to be diagnosed with and die from heart disease than cancer, and yet many believe cancer is more common and their personal risk of cancer is higher than their heart disease risk. Using nationally representative 2013 Health Information National Trends Survey data, we assessed such beliefs and examined sociodemographic and psychological factors and health behaviors associated with these beliefs. 42.8% of participants rated cancer as more common and 78.5% rated their own cancer risk as equal to or exceeding their heart disease risk. These misperceptions were only modestly correlated. Beliefs about relative population risk were associated with various psychological factors, whereas beliefs about relative personal risk were not. Both beliefs were inconsistently associated with health behaviors. Accuracy in beliefs about cancer and heart disease relative risk and prevalence is low and future research should explore antecedents and consequences of these beliefs.
