Introduction To assess the association between perceived susceptibility of developing cancer and being screened via sigmoidoscopy/colonoscopy and prostate-specific antigen, respectively. Methods Participants aged 35–69, who resided in Alberta, Canada, were enrolled into the study between 2000 and 2008. We used general linear mixed models, adjusted for age, marital status, work status, education, family history and place of residence, to explore the association. Results Perceived susceptibility of developing cancer was associated with both screening tests at baseline and a maximum of 14-year follow-up: (i) colorectal cancer screening – adjusted odds ratios were 1.97 (95% CI = 1.52–2.55) per one-unit increase in participants' personal belief in susceptibility to cancer, and 1.03 (95% CI = 1.00–1.04) per one-percent increase in participants’ estimate of their own chance of developing cancer; (ii) prostate cancer screening – adjusted odds ratios were 1.36 times greater (95% CI = 1.07–1.72), and 1.02 times higher (95% CI = 1.01–1.03), for each respective perceived susceptibility measure. Conclusion Health promotion can focus on targeting and heightening personal perceived susceptibility of developing cancer in jurisdictions with low screening rates for colorectal or prostate cancer.

The Cost

Recognition of the mortality and morbidity associated with prostate cancer has resulted in employer based screening programs. This retrospective cohort study identified the employer costs of prostate cancer screening and referrals due to abnormal test results. The subjects were 385 men enrolled in a workplace screening program at a single employer between 1993 and 1995. Screening consisted of digital rectal examination (DRE) annually for enrolled employees aged 40 years and older, plus annual prostate specific antigen (PSA) testing for those 50 and older, and those 40 and older and considered at high risk. Data related to the health care and lost productivity costs of screening and referrals for abnormal test results were collected and analyzed. The total cost of screening was $44,355, or approximately $56 per screening encounter (788 DREs; 437 PSAs). Abnormal screening tests resulted in 52 referrals. Upon further evaluation, 42% were found to have an enlargement, 29% a node, and 12% benign prostatic hyperplasia. Only one malignancy was found. The total cost of additional referrals was $31,815, or 42% of the cost of screening plus referrals. As the cost per screening encounter was low, prostate cancer screening in the workplace is an efficient alternative.

 Prostate-specific antigen (PSA)-based early detection for prostate cancer is the subject of intense debate. Imple­mentation of organized prostate cancer screening has been challenging, in part because the PSA test is so amenable to opportunistic screening. To the extent that access to cancer screening tests increases in low- and middle-income countries (LMICs), there is an urgent need to thoughtfully evaluate existing and future cancer screening strategies to ensure benefit and control costs. We used Mexico’s prostate cancer screening efforts to illustrate the challenges LMICs face. We provide five considerations for policymakers for a smarter approach and implementation of PSA-based screening.

Objective: To compare all-cause-mortality in screening-detected prostate cancer cases versus non-cases after a median 12.2-year follow-up. Methods: In this prospective, population-based study of 3089 Afro-Caribbean men aged 40–79 years in Tobago, Trinidad and Tobago, West Indies, all men were screened for prostate cancer (serum prostate specific antigen and/or digital rectal exam) one to three times between 1997 and 2007 and followed for mortality to 2012. Among 502 men diagnosed with prostate cancer, 81 younger men underwent radical retropubic prostatectomy. Minimal treatment was available for older men. Survival curves compared all-cause-mortality in cases versus non-cases within 10-year age groups at first screening. Results: There were 350 all-cause-deaths over 34 089 person-years of follow-up. All-cause-survival curves in men aged 60 years or above at first screening did not diverge between cases and non-cases until after 10–12 years of follow-up (p > 0.36). In contrast, among men first screened at age 50–59 years, survival was lower in cases, with survival curves diverging at seven years (p = 0.003). Survival in men aged 50–59 years who underwent prostatectomy was similar to survival in non-cases (p = 0.63). Conclusion: Among men aged 60 years or above, the absence of excess all-cause-mortality among screening-detected prostate cancer cases provides argument against the utility of routine prostate cancer screening in this older population of African descent. However, the significantly poorer survival in men aged 50–59 years with screening-detected prostate cancer, compared with screened men without prostate cancer, along with the potential for prostate cancer treatment to improve survival, supports the continuation of prostate cancer screening in this age group, pending further research to assess the risks and benefits.

BACKGROUND International guidelines recommend avoiding prostate-specific antigen (PSA)-based prostate cancer screening in the elderly when life expectancy is less than 10 years. For younger men, most recommendations encourage a shared decision-making process taking into account patient comorbidities. OBJECTIVE The objective was to assess the performance of PSA-based prostate cancer screening in men older than 74 years and assess whether the presence (vs absence) of comorbidities was related to the performance of PSA testing in younger men aged 50 to 74 years who were eligible for screening. METHODS We analyzed data from the French national health care database (Loire-Atlantique geographic area). We reported the follow-up of two cohorts of men from April 1, 2014, to March 31, 2016: 22,480 men aged over 74 years and 98,107 men aged 50 to 74 years. We analyzed whether these patients underwent PSA testing after 2 years of follow-up and whether PSA testing performance was related to the following patient-related variables: age, low income, proxy measures indicative of major comorbidities (repeated ambulance transportation, having one of 30 chronic diseases, taking 5 or more drugs per day), or proxy measures indicative of specific comorbidities (cancer diseases, cardiovascular diseases, or psychiatric disorders). Statistical analysis was based on a multivariate mixed-effects logistic regression. RESULTS The proportion of patients who underwent a PSA-based screening test was 41.35% (9296/22,480) among men older than 74 years versus 41.05% (40,275/98,107) among men aged 50 to 74 years. The following factors were associated with less frequent PSA testing in men older than 74 years—age (odds ratio [OR] 0.89, 95% CI 0.88-0.89), low income (OR 0.18, 95% CI 0.05-0.69), suffering from a chronic disease (OR 0.82, 95% CI 0.76-0.88), repeated ambulance transportation (OR 0.37, 95% CI 0.31-0.44), diabetes requiring insulin (OR 0.51, 95% CI 0.43-0.60), dementia (OR 0.68, 95% CI 0.55-0.84), and antipsychotic treatment (OR 0.62, 95% CI 0.51-0.75)—whereas cardiovascular drug treatment was associated with more frequent PSA testing (OR 1.6, 95% CI 1.53-1.84). The following factors were associated with less frequent PSA testing in men aged 50 to 74 years—low income (OR 0.61, 95% CI 0.55-0.68); nonspecific conditions related to frailty: suffering from a chronic disease (OR 0.80, 95% CI 0.76-0.83), repeated ambulance transportation (OR 0.29, 95% CI 0.23-0.38), or chronic treatment with 5 or more drugs (OR 0.89, 95% CI 0.83-0.96); and various specific comorbidities: anticancer drug treatment (OR 0.67, 95% CI 0.55-0.83), diabetes requiring insulin (OR 0.55, 95% CI 0.49-0.61), and antiaggregant treatment (OR 0.91, 95% CI 0.86-0.96)—whereas older age (OR 1.07, 95% CI 1.07-1.08) and treatment with other cardiovascular drugs (OR 2.23, 95% CI 2.15-2.32) were associated with more frequent PSA testing. CONCLUSIONS In this study, 41.35% (9296/22,480) of French men older than 74 years had a PSA-based screening test. Although it depends on patient comorbidities, PSA testing remains inappropriate in certain populations.

Objectives: The aims of this study were to assess the knowledge of medical students in Lomé about these means of screening for prostate cancer in a context of limited resources and controversy about prostate cancer screening, and to identify the determinants associated with these results. Methods: This was a prospective descriptive and cross-sectional study conducted in the form of a survey of medical students regularly enrolled at the Faculty of Health Sciences of the University of Lomé for the 2019–2020 academic years. Results: Of the 1635 eligible students, 1017 correctly completed the form, corresponding to a rate of 62.20%. The average age was 22 ± 3.35 years. The sex ratio (M/F) was 2.5. Undergraduate students were the most represented (53.69%). Students who had not received any training on prostate cancer were the most represented (57.13%). Only 12.88% of the students had completed a training course in urology. Concerning the prostate-specific antigen blood test, there was a statistically significant relationship between the students’ knowledge and some of their socio-demographic characteristics, namely age (p value = 0.0037; 95% confidence interval (0.50–1.77)); gender (p value = 0.0034; 95% confidence interval (1.43–2.38)); study cycle (p value ˂ 0.0001; 95% confidence interval (0.56–5.13)) and whether or not they had completed a placement in a urology department (p value ˂ 0.0001; 95% confidence interval (0.49–1.55)). On the contrary, there was no statistically significant relationship between students’ knowledge of the digital rectal examination and their study cycle (p value = 0.082; 95% confidence interval (0.18–3.44)). Conclusion: Medical students in Lomé have a good theoretical knowledge and a fair practical level of the digital rectal examination clinical examination and an average theoretical knowledge and a below average practical level of prostate-specific antigen, increasing however along the curriculum in the context of prostate cancer screening.
