Project description:BackgroundThe aim of this study was to evaluate the knowledge, attitudes and behaviors towards prostate cancer and its prevention.MethodsA cross-sectional survey was conducted on a random sample of 625 fathers of students attending eight public schools. The self-administered questionnaire included questions on: socio-demographic characteristics, personal and familiar medical history of prostate cancer, knowledge about prostate cancer and the prostate-specific antigen (PSA) test, perception of risk towards prostate cancer, perception of the benefits of having a PSA-test, willingness to receive the PSA-test and sources of and needs of information regarding prostate cancer and the PSA-test.Results72.7% of respondents had heard about the PSA-test and 51.1% of those had heard about it through their physicians. This knowledge was higher: in men with older age, in those that had a higher level of education, in those who had a relative with prostrate problems or prostate cancer and in those with prostate problems. Perceived personal risk of contracting prostate cancer was associated with a higher level of education, in those who had received information about prostate cancer from a physician and in those with prostate problems. Only 29.6% of men had undergone a PSA-test and 59.4% were willing to do so in the future. The significant predictors of the willingness to receive a PSA-test were the belief that the PSA-test was useful, the perception of not very good personal health status, and need of additional information about the PSA-test.ConclusionRespondents have a moderate knowledge about prostate cancer and a good propensity to undergo the PSA-test. Therefore, it would be necessary to increase information on the risks of prostate cancer and the benefits of prostate cancer prevention.

Project description:The incidence of anal cancer has increased in the past decade, especially among men who have sex with men (MSM) and HIV-infected individuals. There is controversy about whether to routinely screen for anal cancer in MSM.To determine whether current anal cancer screening behaviors, intention, and concern differ by HIV serostatus and to identify characteristics of men who intend to seek anal cancer screening.Cross-sectional analysis of data collected from 901 HIV-infected and 1,016 HIV-uninfected MSM from the Multicenter AIDS Cohort Study (MACS) in 2005-2006.Self-reported anal cancer screening history, attitudes, and intentions.A history of anal warts was relatively common in these men (39%), whereas having a recent anal Pap test (5%), intention to seek anal cancer screening in the next 6 months (12%), and concern about anal cancer (8.5%) were less common. Intention to seek anal cancer screening was associated with enabling factors (screening availability, health insurance), need factors (HIV-infection, history of anal warts), concern about anal cancer, and recent sexual risk taking. Among four large US cities, there was significant regional variability in anal cancer screening behaviors, intention, and concern (all p<0.001). Most MSM (76%) indicated they would go to their primary care physician for an anal health problem or question.This study demonstrates a low rate of anal cancer screening and intention to screen among MSM. As more evidence emerges regarding screening, primary care physicians should be prepared to discuss anal cancer screening with their patients.

Project description:Background:Late diagnosis of prostate cancer is common in low and middle income countries and contributes to high morbidity and mortality of the disease. Utilization of prostate cancer screening services plays a major role in prevention of adverse outcomes. However, there is limited information on the knowledge about, the perceived risk of, and the utilization of prostate cancer screening in Tanzania. Objective:To determine knowledge and perceived risk of prostate cancer, and the utilization of prostate cancer screening services, and associated factors, among men in Dar es Salaam, Tanzania. Design:A population-based cross-sectional study involving men aged 40 years and above living in Dar es Salaam was conducted between May and August, 2018. Methodology:Participants were recruited through multistage random sampling and took part in structured face-to-face interviews. Categorical variables were summarized using proportions while continuous variables were summarized as medians and inter-quarterly range (IQR). Chi square test was used to compare differences between proportions, and logistic regression modelling was used to determine factors associated with utilization of prostate cancer screening. Both crude and adjusted odds ratios (OR), with corresponding 95% confidence intervals, are reported. All analyses were two-tailed and the significance level set at 5%. Results:A total of 388 men with a median age of 53 years (IQR 44-55) participated. Half (52.1%) had poor knowledge about prostate cancer and prostate cancer screening. A third (32.3%, n = 125) perceived the risk of prostate cancer to be low. Only 30 respondents (7.7%) had ever been screened for prostate cancer. Utilization of prostate cancer screening services was independently associated with age above 60 years [AOR?=?21.46, 95% CI: 6.23, 73.93], monthly income above 305 US Dollars [AOR?=?15.68, 95% CI: 4.60, 53.48], the perceived risk of prostate cancer [AOR?=?16.34, 95% CI: 7.82, 14.92] and knowledge about prostate cancer [AOR?=?67.71, 95% CI: 8.20, 559.57]. Conclusions:Knowledge about prostate cancer and prostate cancer screening services was low among men in Dar es Salaam with a third perceiving themselves to be at no risk for the disease. Utilization of screening services was low and associated with low income, younger age, low perceived risk of prostate cancer and low knowledge about the disease. Intervention measures aiming to increase knowledge about prostate cancer and screening services, and affordable provision of services, are urgently called for.

Project description:This study explores knowledge, attitudes and lifestyle behaviors related to cancer in a sample of adolescents. Data were collected through a self-administered questionnaire. 871 adolescents agreed to participate, with a response rate of 96.8%. Only 26.1% had a good level of knowledge on most risk factors for cancer. Adolescents with both parents employed, with a personal, familiar or friend history of cancer or having received information about cancer prevention from a physician, were more likely to have good knowledge about the risk factors for cancer. In total, 41% of participants declared that they consumed alcohol and 25.3% declared they were current smokers, 19.2% consumed fruits or vegetables more than once a day and 75.2% reported poor physical activity. Older adolescents, with a personal, familiar or friend history of cancer, not having one parent in the healthcare sector or not physically active were significantly more likely to be current smokers, whereas physical activity was significantly more likely in adolescents who had been informed by physicians on cancer prevention, and had one parent in the healthcare sector. This study highlights a need for improved education of adolescents about cancer prevention and lifestyle cancer-related behaviors.

Project description:Diabetic men have decreased risk for prostate cancer (PCa) overall and lower PSA compared to non-diabetics. This may affect the outcomes of PSA-based screening. We investigated the effect of PSA-based screening at 4-year intervals on PCa incidence and mortality separately among users and non-users of antidiabetic medication with the hypothesis that screening would detect less low-grade cancer and more high-grade cancer in diabetic men. A cohort of 80,458 men from the Finnish Randomized Study of Screening for Prostate Cancer (FinRSPC) were linked to national prescription database to obtain information on antidiabetic medication purchases. PCa risk and mortality were compared between the FinRSPC screening arm (SA) and the control arm (CA) separately among users and non-users of antidiabetic medication. Among antidiabetic medication users median PSA was lower than in non-users (0.93 and 1.09 ng/ml, respectively, P for difference = 0.001). Screening increased overall PCa incidence compared to CA after the first screen both among medication users and non-users (HR 1.31, 95% CI 1.08-1.60 and HR 1.55, 95% CI 1.44-1.66, respectively). On the second and third screen the difference between SA and CA attenuated only among medication users. Detection of Gleason 6 tumors was lower among medication users, whereas no difference was observed in detection of Gleason 8-10 cancers. Concordantly, screening affected PCa mortality similarly regardless of antidiabetic medication use (HR 0.38, 95% CI 0.14-1.07 and HR 0.19, 95% CI 0.11-0.33 among users and non-users after three screens, respectively. P for difference = 0.18). Median PSA is lower in men using antidiabetic drugs than among non-users. Systematic PSA screening detects less low-risk tumors among medication users, whereas detection of high-risk tumors and mortality effects are similar regardless of medication use. This suggests that antidiabetic medication users may form a suitable target group for PCa screening, with less screening-related overdiagnosis of indolent tumors.

Project description:IntroductionThe primary objective of the ReIMAGINE Prostate Cancer Screening Study is to explore the uptake of an invitation to prostate cancer screening using MRI.Methods and analysisThe ReIMAGINE Prostate Cancer Screening Study is a prospective single-centre feasibility study. Eligible men aged 50-75 years with no prior prostate cancer diagnosis or treatment will be identified through general practitioner practices and randomly selected for invitation. Those invited will be offered an MRI scan and a prostate-specific antigen (PSA) blood test. The screening MRI scan consists of T2-weighted, diffusion-weighted and research-specific sequences, without the use of intravenous contrast agents. Men who screen positive on either MRI or PSA density will be recommended to have standard of care (National Health Service) tests for prostate cancer assessment, which includes multiparametric MRI. The study will assess the acceptability of an MRI-based prostate screening assessment and the prevalence of cancer detected in MRI-screened men. Summary statistics will be used to explore baseline characteristics in relation to acceptance rates and prevalence of cancer.Ethics and disseminationReIMAGINE Prostate Cancer Screening is a single-site screening study to assess the feasibility of MRI as a screening tool for prostate cancer. Ethical approval was granted by London-Stanmore Research Ethics Committee Heath Research Authority (reference 19/LO/1129). Study results will be published in peer-reviewed journals after completion of data analysis and used to inform the design of a multicentre screening study in the UK.Trial registration numberClinicalTrials.gov Registry (NCT04063566).

Project description:BACKGROUND:In Zambia, cervical cancer screening was started in 2006 and the human papillomavirus vaccine was piloted in 2013. Nevertheless, cervical cancer remains the leading cancer. It is assumed that knowledge, social interaction, health behaviors and religion are factors that can influence screening and vaccination practices. This study addresses the question, what is the relationship between knowledge about cervical cancer, attitudes, self-reported behavior, and immediate support system, towards screening and vaccination of cervical cancer of Zambian women and men. The results of this study serve as a basis for future research, an input for improvement and adjustment of the existing prevention program and build on documented health behavior frameworks. METHODS:A cross-sectional mixed methods study was conducted from February to May 2016. Two separate questionnaires were used to collect data from women (N?=?300) and men (N?=?300) residing in Chilenje and Kanyama (two townships in the capital city Lusaka). Respondent's knowledge of cervical cancer was operationalized by grading their ability to correctly identify causes and protective factors if they were aware of cervical cancer. Besides providing descriptive statistics of all study variables, we tested four research hypotheses concerning the link between knowledge, attitudes and practices suggested by the literature, by applying appropriate statistical tests (chi square test, analysis of variance, logistic regression). RESULTS:Less than half of the respondents (36.8%) had heard of cervical cancer, 20.7% of women had attended screening and 6.7% of the total sample had vaccinated their daughter. Knowledge of causes and prevention was very low. There was a strong association between having awareness of cervical cancer and practicing screening (odds ratio?=?20.5, 95% confidence interval?=?[9.214, 45.516]) and vaccination (odds ratio?=?5.1, 95% confidence interval?=?[2.473, 10.423]). Social interactions were also found to greatly influence screening and vaccination behaviors. CONCLUSIONS:The low level of knowledge of causes and prevention of cervical cancer suggests a need to increase knowledge and awareness among both women and men. Interpersonal interactions have great impact on practicing prevention behaviors, for instance, vaccination of daughters.

Project description:To assess the correlates for bisexual behaviors, HIV knowledge, and HIV/AIDS-related stigmatizing/discriminatory attitudes among men who have sex with men (MSM).A cross-sectional survey among MSM was conducted in 2011 to provide demographics, sexual behaviors, HIV knowledge, HIV/AIDS-related stigmatizing/discriminatory attitudes, and services in Jinan, Qingdao, and Yantai of Shandong Province of China.Of 1230 participants, 82.8% were single, 85.7% aged <35 years, and 47.2% received college or higher education. There were 28.6% MSM who reported to be married or cohabitating or ever had sex with woman in the past 6 months (P6M). 74.5% had ≥6 HIV-related knowledge score. The average total score of stigmatizing/discriminatory attitude was 37.4±4.4(standard deviation). Bisexual behavior was independently associated with higher levels of HIV/AIDS-related stigma/discrimination(AOR = 1.1, 95% CI:1.0-1.1), older age(AOR = 1.2, 95%CI:1.1-1.2), and lower HIV-related knowledge score(AOR = 1.6, 95%CI:1.2-2.2). HIV knowledge score ≥6 was independently associated with lower levels of HIV/AIDS-related stigma/discrimination(AOR = 1.3, 95%CI:1.2-1.3), less bisexual behaviors(AOR = 0.6, 95%CI:0.5-0.9), ever received a test for HIV in the past 12 months (P12M)(AOR = 3.2, 95%CI:2.3-4.5), college or higher level education(AOR = 1.9, 95%CI:1.4-2.6), consistent condom use with men in P6M(AOR=6.9, 95%CI:4.6-10.6), recruited from internet or HIV testing sites(AOR = 11.2, 95%CI:8.0-16.1) and bars, night clubs, or tea houses(AOR = 2.5, 95%CI:1.7-4.8). Expressing higher levels of HIV/AIDS-related stigmatizing/discriminatory attitudes was independently associated with bisexual behaviors(Aβ = 0.9, 95%CI:0.4-1.4), lower HIV-related knowledge score(Aβ = 3.6, 95%CI:3.0-4.1), the number of male sex partners in the past week ≥2(Aβ = 1.4, 95%CI:1.0-1.9), unprotected male anal sex in P6M(Aβ = 1.0, 95%CI:0.5-1.6), and inversely associated with ever received HIV test(Aβ = 1.4, 95%CI:0.8-2.0) and peer education in P12M(Aβ = 1.4, 95%CI:0.9-1.9).HIV/AIDS-related stigmatizing/discriminatory attitudes were associated with bisexual behaviors, low HIV testing rate, lower HIV-related knowledge and risk behaviors. This study called for innovative programs that would reduce HIV/AIDS-related stigmatizing/discriminatory attitudes and bisexual behaviors and improve the uptake of prevention service among MSM.

Project description:Underutilization of screening mammography by Latinas continues unabated and may contribute to disparities in disease-free survival and mortality.Comparison of two discussion group-centered educational interventions at enhancing breast cancer knowledge, breast self-exams (BSE), and screening mammography.Pre-test post-test study design. Two cohorts of 200 Latinas each participated in survey screening and discussion groups at baseline. One cohort also viewed an animated video and had BSE training. Breast cancer knowledge, self-reported BSE and mammography history were measured at baseline and three months post-intervention.Breast cancer knowledge scores were good for both groups at baseline, and significantly increased at three month follow-up for both groups (p<.05) but no significant difference was observed between groups at baseline or post-intervention.Community-based discussion groups are a cost-effective method for improving breast cancer knowledge and promoting screening behaviors.

Project description:Men with prostate cancer suffer substantially from bone-related complications. Androgen deprivation therapy itself is a cause of loss of bone mineral density and is associated with an increased incidence of osteoporotic fractures. In advanced disease, bone is by far the most common site of metastasis. Complications of bone metastases prominently include pain and the potential for skeletal events such as spinal cord compression and pathologic fractures. Elevated osteoclast activity is an important aspect of the pathophysiology of both treatment-related osteoporosis and skeletal complications due to metastases. The osteoclast is therefore a therapeutic target. Denosumab is a fully human monoclonal antibody to receptor activator of nuclear factor-?-B ligand that was designed to potently inhibit osteoclast activity and is the central focus of this review. Bisphosphonates, radiopharmaceuticals and systemically-active hormonal agents such as abiraterone acetate and enzalutamide have each been shown to improve skeletal morbidity in specific clinical situations. Denosumab is the only agent that has been shown to prevent osteoporotic fractures in men receiving androgen deprivation therapy and at elevated risk for fracture. It has also demonstrated superiority to the potent bisphosphonate zoledronic acid for the prevention of skeletal-related events in men with castration-resistant prostate cancer metastatic to bone. Efficacy and toxicity data will be discussed.
