Awareness of general public towards cancer prostate and screening practice in Arabic communities: a comparative multi-center study

Prostate cancer across four countries in the Middle East: a multi-centre, observational, retrospective and prognostic study

Prostate cancer (PC) is the second most prevalent cancer in males, with a steadily increasing incidence in the Middle East (ME). The aim of this study was to capture real-world data on the characteristics, disease progression, and treatment patterns among PC patients in the ME. This was a retrospective, observational, multi-centre study conducted across ten hospitals/research centers in Lebanon, Kingdom of Saudi Arabia, Iraq and Kuwait. Data were abstracted from medical records of 615 male patients who were diagnosed with PC between January 2012 and the site initiation date (December 2018-May 2019) and received at least one PC treatment/intervention. The observation period ranged between 84 and 88 months. Data were collected on demographics, clinical characteristics, time to progression to the subsequent clinical state or therapy (progression from localised/locally advanced PC to castration and to metastatic PC (metastatic castration-sensitive PC (mCSPC) or metastatic castration-resistant PC (mCRPC)), progression from mCSPC to mCRPC, and mCRPC patients' progression to first subsequent line of therapy), treatment patterns, and mortality. Most patients had localised/locally advanced PC (57.7%), followed by mCSPC (37.4%), and mCRPC (4.1%) at the time of inclusion in the study. Most patients were at tumours, nodes and metastases (TNM) stage IIIa (40.1%) or TNM stage IVb (27.8%) at study entry. Median time to metastatic disease, castration-resistance and next line therapy was 84 months (95% CI: 68-84), 41 months (95% CI: 30-56) and 7 months (95% CI: 0-41), respectively. The mortality rate was 3.6%. Disease progression was most common among patients with mCSPC (35.1%) or mCRPC (14.8%), and treatment discontinuation was most common among patients with mCRPC (36.6% treatments discontinued). The results show that most patients were at an advanced TNM stage at study entry, suggestive of a lack of awareness regarding PC. Disease progression was most common among patients with metastatic disease, reflecting the challenge of treating metastatic disease and highlighting the need for novel treatments.

Awareness and prevalence of self-reported benign prostatic hyperplasia: a cross-sectional study in Saudi Arabia

Background

Benign prostatic hyperplasia (BPH) is a prevalent condition in older men, causing significant morbidity. Despite recent progress, essential concerns of the disease remain under-researched. This study aims to assess knowledge and estimate self-reported prevalence of BPH in Saudi Arabian men. Understanding BPH prevalence in Saudi Arabia is essential for healthcare planning, resource allocation, public awareness, early detection, intervention, research, and addressing regional variations.

Method

A cross-sectional study was conducted from February to May 2022 using a validated questionnaire. Univariate and multivariate statistical methods assessed knowledge of BPH among 559 adult Saudi men (mean age: 47.2 years) and its association with demographic variables.

Results

The self-reported prevalence rate of BPH for Saudi Arabian men was 12.0%. Most adults (74.2%) were aware that BPH is a risk factor for prostate cancer and 75% were aware of the increased risk of BPH in older people. Furthermore, 44.5% of participants associated nocturia with BPH, while 76.6% related urinary tract infection (UTI) with BPH. The study demonstrated a significant association between BPH awareness and marital status (p = 0.02), level of education (p = 0.02), and employment status (p = 0.04).

Conclusion

While men in Saudi Arabia generally had sufficient knowledge about BPH, there was a knowledge gap regarding certain risk factors like obesity and cardiac diseases. To address this, an educational program should be developed for both the general population and those at high risk of BPH.

Knowledge and Awareness of Screening for Prostate Cancer Risk Factors and Symptoms Among the General Population in Tabuk City, Saudi Arabia

Background Early-stage prostate cancer may not show any signs. Digital rectal examination and the prostate-specific antigen test are frequently used in the screening for prostate cancer. The objective of this research is to assess the knowledge and awareness of screening prostate cancer among males in Tabuk, Saudi Arabia. Methodology A cross-sectional study was performed among Saudi males in Tabuk City. A structured interviewing technique based on a questionnaire was used based on the objectives and research questions. Data were collected by well-trained data collectors from the general population in Tabuk City who were randomly chosen in proportion to the city's population density. A multivariate logistic regression analysis was done to evaluate the variables related to knowledge and awareness in this study. Results This questionnaire was completed by a total of 417 male participants. In the studied group, 86.8% of participants had heard about prostate cancer through friends (59%), TV/radio/newspaper (53.24%), and other health services (41.49%). In addition, around 67.6% of participants knew about the prostate cancer screening test. In addition, 32.4% of participants had no prior knowledge of prostate cancer or a screening test. Conclusions There was a good level of awareness and attitude toward screening methods for prostate cancer (54.7%). Aside from having good knowledge regarding prostate cancer symptoms among males in Tabuk City, all participants with regard to demographic distribution showed a significant level of good knowledge and awareness of screening prostate cancer methods and the necessity of performing regular prostate examinations.

Awareness of prostate cancer and its associated factors among male patients attending care in the urology unit at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia

BACKGROUND

Globally, prostate cancer is the most common cancer among men. It is the second most common cause of cancer-related deaths in men. Symptoms may be non-specific and may not present until the cancer has progressed. Raising awareness, knowing risk factors and symptoms and seeking early medical attention is critical for prevention and detection. The objective of this study is to assess the level of awareness of prostate cancer among male patients attending care in a urology unit in Ethiopia.

METHODS

We conducted a cross-sectional study among 241 male patients at Tikur Anbessa Specialized Hospital from February to April 2021. Data were collected using an interviewer-administered questionnaire adapted from published studies and cancer awareness measurement tools. We used EpiData V.4.6.0 and SPSS V.26 for data entry and analysis. Descriptive statistics and linear regressions were used for analyses. Bivariate and multivariate linear regression analysis identified factors associated with prostate cancer awareness. Adjusted odd ratio (AOR) at 95% CI and p value<0.05 were considered statistically significant.

RESULTS

A total of 250 patients were approached, and 241 (96.4%) responded. The mean scores for awareness of prostate cancer risk factors, symptoms, screening and prevention were 41.2%, 43.8%, 44.7% and 49.5%, respectively. Families with an average monthly income of more than 8900 ETB (Ethiopian birr), having heard about prostate cancer, having a regular source of care every six months or more, having a history of hospitalisation and having healthcare providers as the main source of information were all significantly associated with awareness of prostate cancer.

CONCLUSION

The findings of this study indicate that male patients have a relatively low level of awareness of prostate cancer risk factors, symptoms, screening and prevention. There should be more public awareness initiatives to educate men in Ethiopia on the risk factors, symptoms, screening and prevention of prostate cancer.

Public Knowledge, Practice, and Attitude Regarding Cancer Screening: A Community-Based Study in Saudi Arabia

(1) Background: Cancer screening tests discover cancer at early stages, even before symptoms appear. When abnormal tissues or a malignant mass is found early, treatment and cure rates are improved. In late stages, the cancer may have grown and metastasized. This can negatively affect cancer treatment and reduce the overall survival rate. Screening tests are performed when a person is asymptomatic. Public awareness about cancer screening is crucial for the success of cancer screening programs and for consequently decreasing the morbidity and mortality rate due to cancer. (2) Aim: Assess the knowledge and perception of the community regarding cancer screening in Saudi Arabia. (3) Methodology: A descriptive cross-sectional study targeting the general population of Saudi Arabia was conducted from January to June 2022. The data were collected using a structured validated electronic questionnaire. The study questionnaire covered participants' personal data, medical history, source of data, and participants' knowledge, attitude, and practice items. The questionnaire was used as a digital survey and was distributed electronically to the target population. (4) Results: A total of 1313 participants completed the study questionnaire. The participants' ages ranged from 18 to 67 years, with a mean age of 28.3 ± 11.4 years old. Overall, 60.4% of the study participants knew about cancer screening. Regarding the benefits of cancer screening, 91.8% of the participants reported knowing that the early detection of cancer helps treatment, and 81.1% knew that the early detection of cancer improves treatment outcomes. Moreover, 441 (33.6%) of the participants had good knowledge regarding cancer and cancer screening, while 872 (66.4%) had poor levels of knowledge. Furthermore, 106 (8.1%) of the participants underwent cancer screening. (5) Conclusions: The study results revealed that participants' awareness regarding cancer and cancer screening was low, especially for approaches to reduce cancer risk. Additionally, the study participants' practice regarding cancer screening was low. The health care authority should plan for population-based efficacious cancer screening programs. In addition, cancer screening information and the benefits of early detection can be disseminated through social media to target the desired populations.

Variables Associated with False-Positive PSA Results: A Cohort Study with Real-World Data

(1) Background: There are no real-world data evaluating the incidence of false-positive results. We analyzed the clinical and analytical factors associated with the presence of false-positive results in PSA determinations in practice. (2) Methods: A prospective cohort study of patients with a PSA test was performed in clinical practice. We followed the patients by reviewing their medical records for 2 years or until the diagnosis of PCa was reached, whichever came first. (3) Results: False-positive PSA rate was 46.8% (95% CI 44.2-49.2%) and false-negative PSA rate was 2.8% (95% CI 2-3.5%). Patients aged 61-70 years and those over 70 years were more likely to have a false-positive result than those under 45 years (aOR 2.83, 95% CI 1.06-7.55, p = 0.038, and aOR 4.62, 95% CI 1.75-12.22, p = 0.002, respectively). Patients with urinary tract infection were more likely to have a false-positive result (aOR 8.42, 95% CI 2.42-29.34, p = 0.001). Patients with diabetes mellitus were less likely to have a false-positive result (aOR 0.63, 95% CI 0.41-0.98, p = 0.038); (4) Conclusions: This study has generated relevant information that could be very useful for shared decision making in clinical practice.

Awareness about prostate cancer and its screening in Medina, Jeddah, and Makkah, Saudi Arabia population

Background:

Prostate cancer (PCa) is a global burden on public health; it has been ranked as the second common cancer worldwide, with 1.3 million new cases in 2018. Developed countries have a higher incidence than in developing countries. Because of the lack of studies on PCa in Saudi Arabia, our study aims to measure the awareness about PCa and knowledge of PCa screening practices among men in Medina, Jeddah, and Makkah, Saudi Arabia.

Methodology:

A cross-sectional study conducted among males in Medina, Jeddah, and Makkah, Saudi Arabia, from 2^nd to 10^th July 2020, using a validated questionnaire. The sample size was 1212 participants. Data collected through an online questionnaire. All data analyses performed using (SPSS) software, using the Chi-square test for bivariate analysis. All levels of significance were set at P < 0.05.

Results:

We collected 1212 completed surveys, with mean ages of 36 years (standard deviation ± 12.77). We found that 77% of participants heard about PCa, and 52.5% heard about PCa screening tests. This study showed that only 10.6% of all participants had good knowledge, 41.9% had fair knowledge, and 47.5% had poor knowledge. Only 3.9% of participants had experienced the prostate-specific antigen test.

Conclusion:

The study showed that the level of knowledge of PCa is low. Thus, community and individuals should collaborate to increase awareness by having more awareness campaigns, disseminating the information through the media, and encouraging men to do screening tests as indicated. In addition, including more Saudi Arabia cities in future studies is preferable to have more precise outcomes.

Early Detection of Prostate Cancer: Self-Reported Knowledge and Attitude of Physicians in Jordan

Prostate cancer (PC) screening aims to detect PC in early stages, amenable to curative treatment and reduction in disease morbidity and mortality. However, PC screening may be associated with overdiagnosis and complications of unnecessary treatment for indolent disease. Therefore, careful patient selection for PC screening is critical to avoid overestimation and missed diagnosis. The aim of this study was to assess physicians’ knowledge and attitude towards early detection of PC in Jordan and whether their knowledge is an important predictor of their attitude. An electronic, self-reported questionnaire was used to collect data on demographics, knowledge, and attitude of physicians regarding early detection of PC. The participants’ responses were analyzed using descriptive statistics and multiple linear regression. Around 296 physicians agreed to participate in this study. Most respondents were males (75.7%), residents (34%), practiced medicine more than 15 years (29%) and graduated (81.4%) from local universities. Surprisingly, only 28.4% recognized PC as a non-self-detected disease and less than one-half (48.6%) were aware that PC screening tests are not enough to exclude a diagnosis of PC. The median knowledge Percent of Maximum Possible (POMP) score was 59%. Around two-thirds of participants showed a positive attitude towards early detection of PC (median attitude POMP score was 66%). Higher attitude scores were significantly associated with younger age, those working in private hospitals, and those having higher knowledge POMP score (P < .05). This study highlighted that most physicians demonstrated a positive attitude towards PC screening but with moderate level of knowledge that is considered an important predictor of their attitude towards PC early detection. Thus, improving knowledge and awareness of physicians should be considered as a strategy to improve their attitude towards prostate screening practices and informing men of the importance of regular screening.

High rates of advanced prostate cancer in the Middle East: Analysis from a tertiary care center

Objectives:

Prostate cancer incidence is increasing in the Middle East (ME); however, the data of stage at the diagnosis and treatment outcomes are lacking. In developed countries, the incidence of de novo metastatic prostate cancer ranges between 4% and 14%. We hypothesized that the rates of presentation with advanced disease are significantly higher in the ME based on clinical observation. This study aims to examine the stage at the presentation of patients with prostate cancer at a large tertiary center in the ME.

Methods:

After Institutional Review Board approval, we identified the patients diagnosed with prostate adenocarcinoma and presented to a tertiary care center between January 2010 and July 2015. Clinical, demographic, and pathological characteristics were abstracted. Patients with advanced disease were stratified according to tumor volume based on definitions from practice changing clinical trials. Descriptive and Kaplan–Meier survival analysis was used.

Results:

A total of 559 patients were identified, with a median age at the diagnosis of 65 years and an age range of 39–94 years. Median prostate-specific antigen (PSA) at the presentation was 10 ng/ml, and almost a quarter of the men (23%) presented with metastatic disease. The most common site of metastasis was the bone (34/89, 38%). High-volume metastasis was present in 30.3%, 9%, and 5.2% of the cohort based on STAMPEDE, CHAARTED, and LATITUDE trial criteria, respectively.

Conclusion:

This is the first report showing the high proportion of men from ME presenting with de novo metastasis. This could be due to many factors, including the highly variable access to specialist multidisciplinary management, lack of awareness, and lack of PSA screening in the region. There is a clear need to raise the awareness about prostate cancer screening and early detection and to address the rising burden of advanced prostate cancer affecting men in the ME region.

Awareness and knowledge about prostate cancer among male teachers in the Sunyani Municipality, Ghana

Objective

The study was aimed at assessing the awareness and knowledge of prostate cancer (PC) among male teachers in the Sunyani municipality of Ghana.

Methods

This was a cross-sectional study conducted using a structured questionnaire to collect data from 160 male teachers aged 45 years or more, randomly selected from public elementary and high schools in the Sunyani Municipality. Pearson's Chi square and Fishers exact tests were used to examine the association between socio-demographic characteristics and knowledge of PC.

Results

On average, respondents were aged 50±3.95 years. There was a universal awareness of PC. Most of the respondents could identify at least one signs and symptoms of PC (88.1%), risk factors of PC (78.8%), and indicated that PC could be treated through surgery (70.6 %), but only 37.5% of respondents knew about screening tests for PC. The study found 57.5% of them had adequate knowledge about PC. Socio-demographics characteristics were not associated with knowledge about PC. Main sources of information were the television (68%) and radio (57 %).

Conclusion

The outcomes of the study suggest the need for general educational campaigns with emphasis on modalities for the screening of PC using the appropriate media channels for accessibility.

Knowledge and Attitudes of Men in Bahrain Toward Prostate Cancer

OBJECTIVES

Bahrain has one of the highest rates of prostate cancer in the Middle East, when compared to neighboring countries. Therefore, a seminal study was undertaken, investigating the knowledge and attitudes of Arabic men over 50 years and older, who are in the highest risk group for prostate cancer. A secondary objective was to apply inter-professional student learning of research though the inclusion of medical and nursing students in the research team.

DATA SOURCES

A descriptive research design with data collection through a researcher-administered questionnaire. Study participants included 74 men, predominantly of Arabic origin.

CONCLUSION

Whereas the results of this study are generally reflective of the international literature, the study also provides some new and interesting insights into the perspectives of Arabic men. The findings highlight the importance of a culturally sensitive, health awareness programme for men's health and prostate cancer in Bahrain.

IMPLICATIONS FOR NURSING PRACTICE

The study supports the important role of nurses in men's health promotion and disease prevention. An expansion in community nursing roles could facilitate the development of nursing specialist roles in the area of prostate disease prevention. An enhancement of undergraduate nursing student research learning occurs through active engagement with researchers in research projects, where students participate in preparing for research ethics approval, data collection, data analysis and writing for publication. Inter-professional learning is a very valuable experience in lowering traditional barriers between medicine and nursing.

The association between the knowledge on prostate cancer screening with the beliefs and behaviors of Saudi men attending King Khalid University Hospital

Background:

The evidence showed that prostate cancer (PC) is the second most common malignancy in men globally. Unfortunately, it rarely produces symptoms, and the diagnosis is delayed until the tumor is advanced.

Objectives:

To determine the participants’ uptake of prostate cancer screening (PCS). Also, to assess their perceptions regarding PCS. Furthermore, to evaluate the association between patients’ knowledge of PC and their beliefs and behaviors towards PCS.

Methods:

This cross-sectional study recruited men aged older than 40attending the King Khalid University Hospital (KKUH) between October 2020 and March 2021. SMS messages were sent to a random sample of 228 participants, inviting them to participate in an online self-administered questionnaire. The questionnaire consisted of 1- demography and history of PCS; 2- the knowledge questionnaire about PC; 3-the Champion's Health Belief Model (HBM).

Results:

Out of the 228 participants, 45.2% were men aged 60 years and above, 54.4% with college degrees and postgraduate studies, and 92.5% were married. The median knowledge score was 5, and the range was 12. Most men (72.4%) had a low knowledge score, and 79.4% of them did not have a previous PCS. Men aged 60 + were more likely to undergo the screening than their counterparts, with P values of 0.005. Higher knowledge scores were associated with the perceived benefits of prostate-specific antigen (PSA), digital rectal examination (DRE), and health motivation, P values of 0.0001, 0.0001, and 0.02, respectively. PSA and DRE›s perceived barriers were associated with low knowledge scores, P values of 0.0001 and 0.003, respectively. A higher probability of PCS participation was associated with the older age group, a P value of 0.001. Low participation was associated with perceived barriers of DRE, a P value of 0.031.

Conclusion:

The majority of the participants had poor knowledge regarding PC and PCS. Only a fifth of the men did PCS. High knowledge was associated with PSA and DRE perceived benefits and health motivation.

Assessment of knowledge, practice and attitude towards prostate cancer screening among male patients aged 40 years and above at Kitwe Teaching Hospital, Zambia

Background

Prostate cancer is a leading cause of cancer death in men. Evaluating knowledge, practice and attitudes towards the condition is important to identify key areas where interventions can be instituted.

Methods

This was a hospital-based descriptive cross-sectional study aimed at assessing knowledge, practice and attitude towards prostate cancer screening among male patients aged 40 years and above at Kitwe Teaching Hospital, Zambia.

Results

A total of 200 men took part in the study (response rate = 100%). Of the 200 respondents, 67 (33.5%) had heard about prostate cancer and 58 (29%) expressed knowledge of prostate cancer out of which 37 (63.8%) had low knowledge. Twenty-six participants (13%) were screened for prostate cancer in the last 2 years. 98.5% of the participants had a positive attitude towards prostate cancer screening. Binary logistic regression results showed that advanced age (p = 0.017), having secondary or tertiary education (p = 0.041), increased knowledge (p = 0.023) and family history of cancer (p = 0.003) increased prostate cancer screening practice. After multivariate analysis, participants with increased knowledge (p = 0.001) and family history of cancer (p = 0.002) were more likely to practice prostate cancer screening.

Conclusion

The study revealed low knowledge of prostate cancer, low prostate cancer screening practice and positive attitude of men towards prostate cancer screening. These findings indicate a need for increased public sensitization campaigns on prostate cancer and its screening tests to improve public understanding about the disease with the aim of early detection.

Knowledge and Awareness of Prostate Cancer Among Omani Men Attending a Teaching Hospital

Prostate cancer is ranked as the fourth most prevalent cancer in the world and the second most common cancer affecting men. In Oman, prostate cancer is one of the most common cancers among men, with the majority of prostate cancer patients presenting in the more advanced stages of the disease. Public awareness of the risk factors, symptoms and emphasising the importance of seeking early medical attention could help to improve the outcomes and survival rates of prostate cancer patients. The aim of this study is to determine the awareness levels of the risk factors, symptoms and barriers to seeking early medical intervention among adult Omani men. A validated questionnaire measuring the knowledge of risk factors, symptoms and barriers to seeking early medical help was used to collect data from adult Omani men attending a teaching hospital in Muscat, Oman. Out of 720 men who were invited, 600 participated in the study (response rate = 83%). The most recognised risk factor was obesity (366; 61.0%), and the least was sexually transmitted diseases (204; 34.0%); the most recognised symptom was unexplained weight loss (26.5%), the least was changes in seminal fluid (13.3%); the most common barrier to seeking early intervention was "not trusting the medical knowledge of the doctors" (57.5%), the least was "difficulty in arranging transport" (19.5%). Age, education level, marital status and family history of cancer were significantly associated with the participants' knowledge of prostate cancer. Participants received a significant part of their prostate cancer awareness via the social media. National awareness campaigns using social media and information leaflets are needed to educate Omani men on prostate cancer awareness and prevention and to increase trust in the expertise of medical professionals. Further research exploring the barriers to seeking early medical intervention is needed.

Awareness of prostate cancer diagnosis and management among Turkish males: a cross sectional study from Çorum

Introduction: Prostate cancer is the most common malignancy among men in the United States and the second most common cancer in Turkey. The incidence of prostate cancer is increasing in industrialized countries.Aim: The aim of the study was to assess the knowledge about prostate cancer, its diagnosis, and treatment among patients with lower urinary tract symptoms.Methods: This study was performed from January to April 2015 with the patients applied to our clinic. A questionnaire that includes 10 questions was administered to the participants.Results: One hundred fifty-nine participants were included in this study. The participants' ages were between 40 and 82 with a mean age of 61.5 ± 7.9 years. Patient awareness of prostate biopsy and prostate cancer were 21.37 and 71.06%. The main origin awareness of PSA testing is family and friends. On the other hand, if the doctor advises acout prostate biopsy, 47.16% of the patients would accept and 11.31% of them would refuse this invasive procedure.Conclusion: Prostate cancer is one of the important health-related problem among men in the world. Additional researches are needed to investigate the knowledge of prostate cancer among men and the Ministry of Health may take preventive methods to increase the cancer knowledge level of people.

Prostate cancer screening in a low prevalence population. Is it worth it?

OBJECTIVES

To embrace a national screening program for prostate cancer, putting into consideration the cost, and the attitude of the general population towards such screening.

METHODS

Men aged greater than 45 and less than 70 years were invited to participate in the current prospective study conducted at  King Saud University Medical City, Riyadh, Saudi Arabia between December 2014 and July 2015. Those with confirmed high prostate-specific antigen (PSA) (≥4 ng/ml) were referred to the urology clinic, then subjected to magnetic resonance imaging.

RESULTS

  The total cohort screened were 2898, we  found 118 cases with high PSA (≥4 ng/ml). Fifty-two cases (60.4%) were confirmed high PSA. All of them were subjected to MRI and biopsy. The confirmed prostate cancer were 7 cases (0.24%). The age of confirmed prostate cancer cases ranged from 49 years to 68 years, Gleason score for 4 cases was low grade (3+3), while it was 3+4 for 2 cases, and only one case had advanced cancer (3+5). Approximately 12% of cases with high PSA did not show up for confirmation of their results for further examination.

CONCLUSIONS

  The present study recommends against mass screening among Saudi population; however, men before 50 years of age should start PSA blood testing until before 70 years after discussing the benefits and harms of such screening through shared decision making.

With increasing trends of prostate cancer in the Saudi Arabia and Arab World: Should we start screening programs?

Incidence rate for prostate cancer in the Arab World is significantly lower than United States and Europe, it ranges from 5.5% to 39.2%. However, the incidence and the number of deaths is expected to increase. In Saudi Arabia, the crude incidence rate and age standardized incidence rate of prostate cancer are reported to be steadily increasing in between 2001-2008. Only two screening trials were attempted in 2001 and 2009 which yielded an incidence rate of 1.17% and 2.5% respectively. Men in the Arab world are sharing a common characteristic of poor knowledge and poor attitude towards prostate cancer examination and screening practices. They are ill-informed about the PSA test’s strengths and drawbacks because the doctors are not talking to them about the importance of counselling. Men should be encouraged to do PSA testing before the age of 50 and till the age of 70 years. This could be achieved by enhancing their attitude and enriching the knowledge of the physicians towards PSA testing, harms and benefits, through shared decision making, which would increase men’s knowledge scores, reduced their decisional conflict and promote greater involvement in decision making.

Transcultural Adaptation and Validation of Champion's Health Belief Model Scales for Prostate Cancer Screening

BACKGROUND

Examining men's health beliefs regarding prostate cancer screening is a vital issue and requires a reliable and valid scale.

PURPOSE

Modify Champion's Revised Health Belief Model Scale to measure Jordanian men's beliefs about PCS, translate to Arabic, culturally adapt, and test its psychometric prosperities.

METHOD

This was a methodological study in which 432 healthy men were selected by convenient sampling. Analysis included estimation of content validity indices, internal consistency, construct validity, and predictive validity.

RESULTS

Exploratory factor analysis yielded seven significant factors which explained variance 68.9% of variance. Confirmatory factor analysis demonstrated that scale fit the data significantly. Cronbach's alpha coefficient ranged from .83 to .92.

CONCLUSION

Scale was found to be a valid and reliable for use with Jordanian men.

Knowledge, attitudes, and practices towards prostate cancer screening amongst men living in the southern Italian peninsula: the Prevention and Research in Oncology (PRO) non-profit Foundation experience

PURPOSE

We aimed to explore the knowledge, attitudes, and practices towards prostate cancer (PCa) risk factors and prevention amongst men living in the southern Italian peninsula.

METHODS

We retrospectively reviewed data collected during free preventive visits carried out by the Prevention and Research in Oncology (PRO) non-profit Foundation between July 2013 and July 2016. The following data were collected: demographic and clinical features, knowledge about PCa prevention and sources of knowledge, knowledge about PCa risk factors, previous prostate-specific antigen (PSA) test, previous digital rectal examination (DRE), previous prostate ultrasound, and general attitudes towards DRE.

RESULTS

The study population consisted of 2144 Caucasian men living in four regions in the south of Italy (Campania, Calabria, Molise, Puglia). Median age was 59 years. One thousand six hundred and ninety-nine (79.2%) subjects reported knowing the existence of PCa prevention programs. Most of them received information from the media while only 17.1% declared that the information on PCa prevention that they received was from their family physicians. One thousand two hundred seventy-five (59.5%) subjects declared knowing of the existence of PCa risk factors and 41.3% was aware of the existence of both genetic and exogenous factors. The percentage of subjects who reported having had at least one PSA test in their life was 77.8 and 55.4% reported having had a DRE.

CONCLUSIONS

Knowledge about PCa screening amongst male subjects living in southern peninsular Italy is quite high. Knowledge of PCa risk factors is suboptimal and the practice of DRE is underutilized.

Knowledge, attitudes and screening practices regarding prostatic diseases among men older than 40 years: a population-based study in Southwest Nigeria

INTRODUCTION

Despite the global increase in awareness of prostatic diseases resulting from widespread availability of screening tools, there is no evidence that the knowledge, attitudes and screening practices of Nigerian men have improved regarding prostatic diseases.

METHODS

A descriptive cross-sectional study amongst 305 community-dwelling men. Respondents were selected using multi-staged sampling techniques. Knowledge, attitudes and screening practices were determined based on responses to a semi-structured KAP questionnaire. Data were analyzed using SPSS version 18. Pearson's chi-square and Fisher's exact test (two-tail) with level of significance set at 0.05 were used to determine the level of statistical significance. Pearson's correlation coefficient was used to establish correlation between variables.

RESULTS

Mean age of respondents was 63.4±11.8 years. Slightly less than half, 145(47.5%) were aware of prostate cancer (PCa) while only 99(32.5%) and 91(29.8%) were aware of BPH and prostatitis respectively. About a quarter (25.1%) had heard of PSA. The main sources of information were radio and television. Overall, 143(46.9%) respondents had good knowledge while 162(53.1%) had poor knowledge. Sexually transmitted disease was the commonest misconception as the cause of prostatic diseases. Overall, 44.3% had good attitudes. Only 31(10.2%) respondents had ever carried out screening for PCa. Only educational and occupational status had significant associations with level of knowledge and attitudes of participants. The only factor that influenced screening practices was educational status.

CONCLUSION

There is a poor level of knowledge, attitudes and screening practices regarding prostatic diseases in Nigeria. We recommend a widespread public health education to improve knowledge, attitudes and screening practices for prostatic diseases.

Human Kallikrein-2, Prostate Specific Antigen and Free- Prostate Specific Antigen in Combination to Discriminate Prostate Cancer from Benign Diseases in Syrian Patients

BACKGROUND

The high incidence of prostate cancer as the most common malignancy in males in many countries raises the question of developing reliable detection tests. The prostate specific antigen (PSA) test is the most widely used for screening for prostate cancer; however, its low specificity elevates the number of unnecessarily biopsies. Serum human kallikrein-2 (hK2) is considered as a promising marker, and especially its ratio to fPSA, for predicting the presence of malignancy to select the best choice referring to biopsy or surveillance. In this study, we investigated the role of hK2 and its combinations with other markers to discriminate prostate cancer from benign diseases in Syrian patients.

In this prospective oriented cross-sectional cohort study, serum samples were collected from patients referred to many Hospitals in Damascus, Syria, between May 2011 and March 2012, and diagnosed with biopsy proven benign prostate hyperplasia (BPH) or prostate cancer (PCa). Serum was analyzed for hK2, PSA and fPSA, and the ratios of fPSA/PSA and hK2/fPSA were calculated.

RESULTS

We found that mean hK2/fPSA ratios were significantly higher (P=0.01) in prostate cancer patients than in the BPH or control groups. Also the ratio hk2/fPSA gave the largest area under the curve (AUC:0.96) which was significantly larger than for fPSA/PSA (AUC:0.41) indicative of higher specificity.

CONCLUSIONS

Our results demonstrate that the ratio of hK2/fPSA might be superior to the use of fPSA/PSA alone. The hK2 could be shown to enhance the early detection of prostate cancer; especially the ratio hK2/fPSA improves specificity and hence may reduce the number of negative biopsies.

Predictors of Participation in Prostate Cancer Screening among Older Men in Jordan

BACKGROUND

Participation is one of the major factors affecting the long-term success of population-based prostate cancer screening programs. The aim of this study was to explore strong factors linked to participation in prostate cancer screening among older Jordanian adults using the Health Belief Model (HBM).

MATERIALS AND METHODS

Data were obtained from Jordanian older adults, aged 40 years and over, who visited a comprehensive health care center within the Ministry of Health. A pilot test was conducted to investigate the internal consistency of the the Champion Health Belief Model Scale for prostate cancer screening and the clarity of survey questions. Sample characteristics and rates of participation in prostate cancer screening were examined using means and frequencies. Important factors associated with participation in prostate cancer screening were examined using bivariate correlation and multivariate logistic regression analysis.

RESULTS

About 13% of the respondents had adhered to prostate cancer screening guidelines over the previous decade. Four out of the seven HBM-driven factors (perceived susceptibility, benefits and barriers to PSA test, and health motivation) were statistically significant. Those with greater levels of susceptibility, benefits of PSA test and health motivation and lower levels of barriers to PSA testing were more likely to participate in prostate cancer screening. Family history, presence of urinary symptoms, age, and knowledge about prostate cancer significantly predicted the participation in prostate cancer screening.

CONCLUSIONS

Health professionals should focus more on the four modifiable HBM-related factors to encourage older adults to participate in prostate cancer screening. Intervention programs, which lower perceived barriers to PSA testing and increase susceptibility, benefits of PSA testing and health motivation, should be developed and implemented.

Enhancing Knowledge, Beliefs, and Intention to Screen for Prostate Cancer via Different Health Educational Interventions: a Literature Review

BACKGROUND

Prostate cancer is one of the most common cancers affecting men globally, constituting the sixth leading cause of cancer related death in males, and the eleventh leading cause of death from cancer in all age groups. In Jordan, prostate cancer is the third most common cancer in the male population, accounting for one third (6.2%) of cancer related deaths and in 2010 alone, 218 (9.4%) new cases were identified.

OBJECTIVE

To assess the effectiveness of different health education interventions aimed at enhancing knowledge, beliefs and intention to screen for prostate cancer.

MATERIALS AND METHODS

A literature search from January 2000 to April 2015 was conducted using the key words "prostate disease," "educational program," "knowledge," "prostate cancer," "demographic factors and prostate cancer," "knowledge and prostate cancer," "education for patients with prostate cancer," "factors that affect intention to screen," "knowledge, beliefs, and intention to screen for prostate cancer," "impact of prostate educational program on beliefs," and "impact of educational program on intention to screen."

RESULTS

Majority of studies reviewed indicated that men had low levels of knowledge regarding prostate cancer, and mild to moderate beliefs with good intention to screen for prostate cancer.

CONCLUSIONS

Most studies indicated that men's knowledge levels about prostate cancer were poor and they had mild to moderate beliefs and intentions to screen for prostate cancer. Therefore, development of an assessment strategy based on the Health Belief Model seems essential. An effectively designed and implemented educational program can help identify the needs and priorities of the target population.

Frequency of Unnecessarily Biopsies among Patients with Suspicion of Prostate Cancer in Syrian Men

BACKGROUND

The prevalence of prostate cancer is considered high in many countries, and screening tests are very important in order to detect prostate cancer in its early stages; however false positivity with these screening tests means that a lot of patients undergo unnecessary biopsy, which is an invasive procedure, for the confirmatory test. The purpose of this study was to estimate the frequency of unnecessary biopsy cases in patients referred for prostate biopsy in one of the most important and overload cancer centers in Syria.

MATERIALS AND METHODS

Retrospective data for a period of four years between January 2009 and December 2012 were collected in Al- Bayrouni University Medical hospital in Damascus, Syria. The patients from whom data were collected were referred to our histopathological department because of elevated prostate specific antigen (PSA) serum or an abnormal digital rectal examination (DRE). All patients underwent prostatic TRUS-guided biopsies. Diagnosis of prostate cancer (PCa) or benign prostatic hyperplasia (BPH) was based on histopathological examination and prostate cancers cases were graded and scored according to the Gleason score system.

RESULTS

For the 406 patients referred to biopsy, the mean±SD age was 58.4 ±23.3 years. The mean ± SD PSA level was 49.2±21.5 ng/ ml. Of the total we found 237 patients diagnosed with PCa (58. 4%), 166 patients with BPH (40.9%) and 3 cases were unable to be diagnosed (0.7%) because of biopsy collection errors.

CONCLUSIONS

Our study shows that a high percentage of patients are undergoing unnecessary biopsy, which suggests that the performed screening tests had a high level of false positive and may need re-evaluation.

Prostate Cancer in the Arab World: A View From the Inside

The rates of prostate cancer vary by more than 50-fold across different international populations. The aim of this review was to explore the differences in epidemiology and risk factors between the Middle Eastern Arab countries and some of the developed countries in Europe and North America. The age-standardized incidence rate of prostate cancer in the Arab countries is still lower than that in the Western countries, but is steadily increasing with time. Several factors come into play to explain this difference. There are health care systems-related factors such as the lack of good population-based registries, and population-related factors. The latter include the relatively young age structure in the Arab countries, lower reported androgen and prostate-specific antigen levels in Arab men, the effect of genetic differences on prostate cancer risk, the metabolic syndrome paradox, and the protective effect of the Mediterranean diet on a subset of the Arab population. In conclusion, the study of prostate cancer in the Arab world represents a challenge with the currently available cancer care systems and the increase in the burden of the disease. A multinational prospective study to investigate the epidemiology of prostate cancer in the Middle East, with specific attention to country/geographic variability along with a comparative analysis to that of the Western hemisphere is needed.

Histopathologic characterization of prostate diseases in Madinah, Saudi Arabia

AIMS

To delineate the histopathological pattern of prostate diseases and to highlight age variations in prostate specific antigen (PSA) values and histopathological features.

MATERIALS AND METHODS

A retrospective review was made of all prostate biopsy reports seen between January 2006 and December 2013 at the King Fahad Hospital, Madinah, Saudi Arabia. Prostate lesions were tabulated and classified into benign and malignant groups. Histological scoring of adenocarcinomas was accomplished using the Gleason system. PSA values were correlated with Gleason scores.

RESULTS

Of 417 prostate lesions reviewed, 343 (82.3%) were benign and 74 (17.7%) were malignant, giving a benign to malignant ratio of 4.6:1. Benign prostatic hyperplasia (both with and without inflammation) was the commonest prostatic lesion and accounted for 80.3% of all cases and 97.6% of all benign cases. The age range was 20 to 97 years with a mean of 69.2 years and a peak age group at 70-79 years. Seventy one cases of adenocarcinoma accounted for 95.9% of the total of 74 malignant tumors. It showed an age range of 44 to 95 years, a mean age of 70.9 years and peak prevalence in the 80-89 year age group. Gleason score seven was the most frequent (39.4%) in occurrence. Most adenocarcinomas, 41 cases (57.7%), were moderately differentiated (Gleason score of 5-7). PSA values ranged widely between 16-1,865 ng/ml with a mean of 363.4 ng/ml. Elevated PSA (>100 ng/ml) levels were found in 53 (81.6%) patients. There was a statistically significant positive correlation between serum PSA level and Gleason score (p=0.0304).

CONCLUSIONS

Prostatic lesions constitute a significant source of morbidity among adult males in Madinah. Benign prostatic hyperplasia was the commonest benign prostatic lesion and adenocarcinoma was the commonest histological subtype of prostatic cancer.

An early-detection programme for prostate cancer in Saudi men: A call from a tertiary-care centre in the Eastern province

OBJECTIVE

To review the mode of presentation and clinical course of patients with prostate cancer during a specified period, as the detection rate is tending to increase, with most patients presenting at an advanced stage, and yet the overall incidence and prevalence rates are low.

PATIENTS AND METHODS

We retrospectively reviewed all aspects of care for patients who were diagnosed between May 2006 and July 2010.

RESULTS

In all, 76 men had a histologically confirmed prostatic adenocarcinoma diagnosed between May 2006 and July 2010 (mean age 71.1 years, SD 8). The median (range) prostate-specific antigen level at diagnosis was 52 (1.2-16,230) ng/mL. Of the patients, 74% had a Gleason grade of ⩾ 7 on diagnosis, and 64% had extraprostatic disease on presentation. Active surveillance was adopted in four patients, and four others were maintained on watchful waiting. Six patients had a radical prostatectomy, in one of whom it was a salvage procedure. Six patients received external-beam radical radiotherapy, five of whom had neoadjuvant, concurrent and adjuvant hormonal therapy. All remaining patients were treated primarily with androgen-deprivation therapy (ADT). Of the patients on hormonal manipulation, in 56% the cancer became castrate-resistant within the mean (SD) follow-up of 17.2 (15) months. Of patients treated primarily with ADT, 34% died. The death rate among the whole group was 23%. Both percentages include both prostate cancer-specific and non-specific mortality.

CONCLUSION

An advanced stage of disease at presentation mandates an early-detection, hospital-based screening programme. Further research should include many more patients and be based in several centres.

Public awareness of colon cancer screening among the general population: A study from the Western Region of Saudi Arabia

Background: Screening for colon cancer aims at early detection and prompt treatment of the disease. Prior knowledge of the disease will contribute to increased participation. However, barriers to performing screening are not known. Methods: A survey using a questionnaire was presented to patients attending the Outpatient Department of a tertiary hospital in the Western Region of Saudi Arabia, to evaluate the background knowledge of colon cancer screening, the diagnostic methods used for that purpose, and the barriers that may resist the implementation of screening. Results: Six hundred and nineteen questionnaires were distributed. Completed questionnaires that were included in the final analysis numbered 321 (51.9%). Age and gender had no statistically significant association with increased awareness of screening options (p = 0.526 and p = 0.2). However, education played a significant role (p = 0.045). Among the group that agreed to undergo screening, there were 55.3% who were willing to undergo colonoscopy or sigmoidoscopy. Contrary to that, among the group that did not agree to undergo screening, 77.4% of them would undergo radiological screening using barium enema and/or a computed tomography (CT) scan of the abdomen. Conclusion: There is a deficiency of knowledge of colorectal cancer (CRC) screening influenced by an individual's level of education, yet unrelated to age or gender. The endoscopic modality was usually chosen by individuals who were aware of CRC screening. However, the fear of undergoing this investigation, for the same reason, would likely make them decide to choose less invasive testing, using barium enema or a CT of the abdomen.

الوعي العام بفحوصات الكشف عن سرطان القولون بين عامة السكان دراسة من المنطقة الغربية في المملكة السعودية العربية

الملخص

الأهداف: يهدف الكشف المبكر عن سرطان القولون إلى التعرف على المرض وعلاجه مبكرًا. وتسهم المعرفة المسبقة بالمرض في تحسين المشاركة في الفحص وزيادة فاعليته. ولكن العوائق التي تمنع مشاركة الناس في الفحص المبكر غير معلومة.

الطريقة: أجريت استبانة للمرضى في قسم العيادات الخارجية بأحد المستشفيات المرجعية في المنطقة الغربية من المملكة العربية السعودية لتقييم معلوماتهم العامة حول الفحص المبكر عن سرطان القولون، وطرق التشخيص المستخدمة لهذا الغرض, وكذلك معرفة العوائق التي قد تمنعهم من المشاركة فيه. النتائج: وزعت 619 استبانة, ولم يتضمن التحليل النهائي سوى الاستبانات المكتملة بشكل يتوافق مع متطلبات البحث وعددها 312 (51,9%). لم يكن للعمر أو الجنس أي دلالة إحصائية مرتبطة بزيادة الوعي (p = 0.526 وp = 0.2)، وذلك بعكس المستوى التعليمي الذي أظهر ارتباطًا وثيقًا بزيادة الوعي والاهتمام بإجراء الفحص المبكر للقولون (p = 0.045). اتضح أنه من بين المجموعة التي وافقت على المشاركة في إجراء الفحص، أبدى 55,3 % استعدادهم لإجراء منظار القولون أو المستقيم. بينما أظهرت النتائج أن 77,4 % من المجموعة التي رفضت المشاركة في الفحص، يفضلون إجراء الفحص الإشعاعي باستخدام حقنة الباريوم و/أو التصوير المقطعي للبطن كوسيلة للفحص المبكر. خاتمة: يوجد نقص في الوعي والمعرفة العامة بفكرة الفحص المبكر لسرطان القولون والمستقيم، ويرتبط ذلك بالمستوى التعليمي ولكن لا صلة له بعاملي العمر أو الجنس. المعرفة المسبقة بالفحص المبكر ترتبط إيجابًا باختيار التنظير كوسيلة للفحص، إلا أن الخوف من الخضوع لذلك الفحص، رغم المعرفة المسبقة به، قد يجعل المرضى يختارون وسائل أقل توسعًا، مثل حقنة الباريوم أو التصوير المقطعي للبطن.
