RESUMEN
Introducción: El examen físico mediante el tacto rectal es una manera de encontrar temprano el cáncer de próstata. Aunque este resulta de suma importancia en las pesquisas, tiene poca aceptación debido a los tabúes arraigados en la sociedad. Por tanto, es necesario educar a la población masculina. Objetivo: Elevar el nivel de conocimientos sobre el examen y autoexamen de próstata en pacientes mayores de 45 años. Métodos: Se realizó un estudio cuasiexperimental de intervención educativa en un universo constituido por 62 pacientes mayores de 45 años pertenecientes al Policlínico Docente Área Este, de la ciudad de Camagüey. La muestra quedó conformada por 55 pacientes que cumplieron con los criterios de selección del estudio. Se analizaron las variables grupo de edades, nivel educacional; así como los conocimientos sobre las características generales del cáncer de próstata, prevención y control de los factores de riesgo, examen y autoexamen de próstata, antes y después de aplicada la intervención educativa. Resultados: En la muestra analizada predominaron los pacientes de entre 45-49 años (30,9 por ciento) y el nivel educacional técnico medio (43,6 por ciento), mientras se logró elevar el conocimiento en relación a las características generales del cáncer de próstata (40,0/94,6 por ciento), prevención y control de los factores de riesgo (20,0/92,7 por ciento), y de 7,3/87,3 por ciento en lo concerniente al examen y autoexamen de próstata. Conclusiones: Se alcanzaron valores estadísticamente significativos, de manera que se logró elevar el nivel de conocimientos en la muestra estudiada(AU)
Introduction: Examination by digital rectal examination is a way to early find prostate cancer. Although this examination is utmost important in the investigations, it has little acceptance due to the taboos rooted in society. In this sense, it is necessary to educate the male population. Objective: To raise the level of knowledge about prostate examination and self-examination in patients older than 45 years of age. Methods: A quasi-experimental study of educational intervention was carried out in a universe consisting of 62 patients older than 45 years of age from Área Este Teaching Polyclinic, in the city of Camagüey. The sample was made up of 55 patients who met the study selection criteria. The variables were analyzed age group, educational level; as well as knowledge about the general characteristics of prostate cancer, prevention and control of risk factors, prostate examination and self-examination before and after the educational intervention is applied. Results: In the studied sample, patients between 45-49 years of age (30.9percent) and the average technical educational level (43.6percent) predominated, while knowledge was raised in relation to the general characteristics of prostate cancer (40.0/94.6percent), prevention and control of risk factors (20.0/92.7percent), and 7.3/87.3percent regarding prostate examination and self-examination. Conclusions: Statistically significant values were reached, so that the level of knowledge was raised in the sample studied(AU)

Background: The surgery with total mesorectal excision recommended by R. J. Heald in 1982 is the gold standard. Rectal cancer (RC) surgery has a morbidity rate ranging from 6 to 35%, and it can cause functional issues such as sexual, urinary, and bowel dysfunction in the long term. Neoadjuvant chemoradiotherapy (CRT) has been gaining ground in patients with lesions in the middle and lower rectum. The aim of the present study is to present the experience of a reference service in the treatment of RC. Patients and Methods: A retrospective study involving 53 patients diagnosed with RC between January 2017 and December 2019 with follow-up until December 2020. We examined tumor location, disease stage, digital rectal exam findings, carcinoembryonic antigen (CEA), therapeutic modality offered, and follow-up time. Results: A total of 32% of the patients were men and 68% were women, with a mean age of 60 years old. Location: upper rectum in 6 cases, middle rectum in 21 cases, and lower rectum in 26 cases with evolution from 9.8 to 13.5 months. The most frequent complaints were hematochezia and constipation. A total of 36 patients underwent neoadjuvant therapy: 11 complete clinical response (CCR) (30.5%), 20 (55.5%) partial clinical response (PCR), and no response in 5 patients (14%). The follow-up ranged from 12 to 48 months, with a mean of 30.5 months. A total of 25% of the patients had RC that went beyond the mesorectal fascia, and 22.64% had metastases in other parts of the body when they were diagnosed. Conclusion: Neoadjuvant radio and chemotherapy present themselves as an alternative in the treatment of rectal cancer. In 36 patients, 30.5% had a complete clinical response, 55.5% had a partial clinical response, and 14% had no response. It was worth doing the "Watch and Wait" (W&W) to sample. A definitive colostomy was avoided. However, it is necessary to expand the study to a larger follow-up and more patients. Additionally, it is necessary to implement a multicenter study. (AU)

Introducción: El desarrollo de la tecnología con el ultrasonido transrectal ha permitido obtener imágenes diagnósticas de la glándula prostática; su interés deriva de la inmensa frecuencia de problemas clínicos, tanto benignos como malignos. El medio diagnóstico del cáncer de próstata se basa en una biopsia dirigida por ultrasonido transrectal en la mayoría de los casos. Objetivo: Determinar los hallazgos ultrasonográficos y su relación con estudios histopatológico en el diagnóstico de la neoplasia prostática, de los pacientes con sospecha, atendidos en la consulta de urooncología. Métodos: Se realizó un estudio descriptivo transversal en pacientes con sospecha clínica de cáncer prostático, procedentes del servicio de urología en el Hospital Celia Sánchez Manduley en el período comprendido entre julio de 2019 a julio de 2021; que acudieron a consulta con indicación de ultrasonido transrectal. El universo estuvo constituido por 105 pacientes. Se utilizaron criterios de inclusión y exclusión para la selección del universo, previo consentimiento informado de los pacientes. Las variables estudiadas fueron: edad, color de la piel, síntomas clínicos, hallazgos del ultrasonido transrectal, relación ecosonográfica- anatomopatológico. Resultados: Predominó el grupo de edad de 60 a 79 años, de la raza negra, con síntomas urinarios obstructivos bajos, con presencia del nódulo hipoecoico. Predominó la localización ultrasonográfica periférica, así como el adenocarcinoma prostático como hallazgos anatomopatológico encontrado a través de la biopsia. Conclusiones: Se demostró correlación ecográfica-histológica y anatomopatológica(AU)
Introduction: The development of transrectal ultrasound technology has made it possible to obtain diagnostic images of the prostate gland; its interest derives from the massive frequency of clinical problems, both benign and malignant. The diagnosis of prostate cancer is based on a transrectal ultrasound-guided biopsy in most cases. Objective: To determine the ultrasonographic findings and the how they relate with histopathological studies in the diagnosis of prostatic neoplasia in suspected patients treated in the uro-oncology clinic. Methods: A cross-sectional descriptive study was carried out in patients with clinical suspicion of prostate cancer, in the urology service at Celia Sánchez Manduley Hospital from July 2019 to July 2021; they attended the consultation with an indication for transrectal ultrasound. The universe consisted of 105 patients. Inclusion and exclusion criteria were used for the selection of the universe, with the prior informed consent of the patients. The variables studied were age, skin color, clinical symptoms, transrectal ultrasound findings, echosonographic-pathological relationship. Results: Predominance was observed of subjects from the age group of 60 to 79 years, black race, with lower obstructive urinary symptoms, and presence of hypoechoic nodule. Peripheral ultrasonographic location prevailed, as well as prostatic adenocarcinoma as pathological findings found through biopsy. Conclusions: Ultrasound-histological and pathological correlation was demonstrated(AU)

OBJECTIVE: To evaluate the impact of the digital rectal exam (DRE) on PSA measurements and clinical decision-making. METHODS: Healthy male volunteers between 50 and 70 years old were recruited during a 30-day public screening program. PSA levels were measured using two different methods (standard enhanced chemiluminescence immunoassay-ECLIA, and novel immunochromatography assay-ICA/rapid PSA) in the same blood sample. Two blood samples were drawn; first before DRE and the second 30-40 min after DRE. The effect of DRE on PSA levels and its impact on clinical decision-making for individual patients were evaluated based on different biopsy trigger cutoffs. RESULTS: ECLIA-PSA was measured in 74 participants both pre- and 37 ± 5 min post-DRE, mean age 57.2 ± 8.3 years, and mean prostate volume 33.6 (20-80) cm3. Both total and free ECLIA-PSA increased significantly after DRE (mean increase of 0.47 and 0.26 ng/ml, respectively, both p < 0.001). Different internationally accepted biopsy triggers were reached after DRE only: 5 total PSA > 3 ng/ml, 13 increase > 0.75 ng/ml, 3 PSA density > 0.15, and 1 free/total PSA < 0.18. On two occasions, patients were pushed away from biopsy trigger after DRE due to free/total PSA > 0.18. ICA-PSA was detectable (> 2.0 ng/ml) in 5 of 45 measured samples (11%) before DRE and 13/45 (29%) after DRE, p = 0.0316. Four among five detectable ICA-PSA tests increased after DRE. CONCLUSION: Performing DRE immediately before PSA measurement might change the clinical decision-making on a significant number of occasions (roughly 1 in 3); even though the mean increase (0.47 ng/ml) looks deceivingly small. Further studies are required that include gold standard tests (biopsy, or imaging).

Purpose To identify metabolites in humans that can be associated with the presence of malignant disturbances of the prostate. Methods In the present study, we selected male patients aged between 46 and 82 years who were considered at risk of prostate cancer due to elevated levels of prostate-specific antigen (PSA) or abnormal results on the digital rectal examination. All selected patients came from two university hospitals (Hospital Universitario del Valle and Clínica Rafael Uribe Uribe) and were divided into 2 groups: cancer (12 patients) and non-cancer (20 patients). Cancer was confirmed by histology, and none of the patients underwent any previous treatment. Standard protocols were applied to all the collected blood samples. The resulting plasma samples were kept at -80°C, and a profile of each one was acquired by nuclear magnetic resonance (NMR) using established experiments. Multivariate analyses were applied to this dataset, first to establish the quality of the data and identify outliers, and then, to model the data. Results We included 12 patients with cancer and 20 without it. Two patients were excluded due to contamination with ethanol. The remaining ones were used to build an Orthogonal Projections to Latent Structures Discriminant Analysis (OPLS-DA) model (including 15 non-cancer and 10 cancer patients), with acceptable discrimination (Q2 = 0.33). This model highlighted the role of lactate and lipids, with a positive association of these two metabolites and prostate cancer. Conclusions The primary discriminative metabolites between patients with and without prostate cancer were lactate and lipids. These might be the most reliable biomarkers to trace the development of cancer in the prostate.
Objetivo Identificar metabolitos en humanos que pueden estar asociados con la presencia de alteraciones malignas de la próstata. Métodos Se incluyeron muestras de pacientes masculinos entre 46 y 82 años y que se consideraron en riesgo de cáncer de próstata debido a la elevación del antígeno prostático específico (PSA) o el examen rectal anormal. Todos los pacientes seleccionados procedían de dos hospitales universitarios (Hospital Universitario del Valle y Clínica Rafael Uribe Uribe) y se dividieron en dos grupos: Oncológicos (12) vs no oncológicos (20). El cáncer fue confirmado por histología, y ninguno de ellos recibió tratamiento previo. Se aplicaron protocolos estándar a todas las muestras de sangre recolectadas. Las muestras de plasma resultantes se mantuvieron a −80°C y se adquirió un perfil de cada muestra mediante RMN. Se aplicaron análisis multivariantes a este conjunto de datos, primero para establecer la calidad de los datos e identificar valores atípicos, y para modelar los datos. Resultados Se incluyeron 12 pacientes con cáncer y 20 pacientes sin cáncer. Dos pacientes fueron excluidos por contaminación con etanol. Los restantes se utilizaron para construir un modelo OPLS-DA (15 pacientes no oncológicos y diez oncológicos), con una discriminación aceptable (Q2 = 0,33). Este modelo destacó el papel del lactato y los lípidos, encontrando una asociación positiva entre estos dos metabolitos y el cáncer de próstata. Conclusiones Los principales metabolitos discriminativos entre pacientes con cáncer de próstata versus no cáncer fueron el lactato y los lípidos. Estos podrían ser los biomarcadores más confiables para rastrear el desarrollo del cáncer en la próstata.

Rectal trauma is uncommon, but it is usually associated with injuries in adjacent pelvic or abdominal organs. Recent studies have changed the paradigm behind military rectal trauma management, showing better morbidity and mortality. However, damage control techniques in rectal trauma remain controversial. This article aims to present an algorithm for the treatment of rectal trauma in a patient with hemodynamic instability, according to damage control surgery principles. We propose to manage intraperitoneal rectal injuries in the same way as colon injuries. The treatment of extraperitoneal rectum injuries will depend on the percentage of the circumference involved. For injuries involving more than 25% of the circumference, a colostomy is indicated. While injuries involving less than 25% of the circumference can be managed through a conservative approach or primary repair. In rectal trauma, knowing when to do or not to do it makes the difference.
El trauma de recto es poco frecuente, pero generalmente se asocia a lesiones de órganos adyacentes en la región pélvica y abdominal. Estudios recientes han cambiado los paradigmas del manejo tradicional derivados del trauma militar, mostrando mejores resultados en la morbilidad y mortalidad. Sin embargo, las técnicas de control de daños en el trauma rectal aún son controvertidas. El objetivo de este articulo es proponer el algoritmo de manejo del paciente con trauma rectal e inestabilidad hemodinámica, según los principios de la cirugía de control de daños. Se propone que las lesiones del recto en su porción intraperitoneal sean manejadas de la misma manera que las lesiones del colon. Mientras que el manejo de las lesiones extraperitoneales del recto dependerá del compromiso de la circunferencia rectal. Si es mayor del 25% se recomienda realizar una colostomía. Si es menor, se propone optar por el manejo conservador o el reparo primario. Saber que hacer o que no hacer en el trauma de recto marca la diferencia.

Objetivo: identificar os fatores associados à masculinidade no diagnóstico precoce do câncer de próstata. Método: trata-se de uma revisão narrativa realizada nas seguintes bases de dados: SCIELO, LILACS e PUBMED. Após a aplicação dos critérios de elegibilidade, a amostra do estudo foi composta por 14 artigos publicados entre 2000 e 2021. Resultados: os estudos abordam fortemente a influência dos aspectos socioeconômicos e culturais na busca preventiva dos homens pelo autocuidado. Os padrões estipulados pela sociedade dificultam a adesão masculina fazendo-os diminuir a procurar por serviços de saúde em relação às mulheres dificultando o diagnóstico precoce do câncer de próstata. O exame de toque retal encontra-se atrelado à transgressão de sua masculinidade repercutindo no medo de realizá-lo. Conclusão: concepções socioculturais acerca da masculinidade associam-se negativamente à saúde dos homens impondo dificuldades no diagnóstico precoce do câncer e, conseqüentemente, aumentando a mortalidade masculina.(AU)
Objective: to identify the factors associated with masculinity in the early diagnosis of prostate cancer. Method: this is a narrative review conducted in the following databases: SCIELO, LILACS and PUBMED. After applying the eligibility criteria, the study sample was composed of 14 articles published between 2000 and 2021. Results: the studies strongly address the influence of socioeconomic and cultural aspects on men's preventive search for self-care. The standards set by society hinder male adherence, making them less likely to seek health services than women, hindering the early diagnosis of prostate cancer. The rectal examination is linked to the transgression of their masculinity, resulting in the fear of performing it. Conclusion: sociocultural conceptions about masculinity are negatively associated with men's health, imposing difficulties in the early diagnosis of cancer and consequently increasing male mortality.(AU)

ABSTRACT BACKGROUND: Population-wide screening for prostate cancer remains a controversial topic, given the need for an individualized approach to patients regarding the risks and benefits of prostate-specific antigen testing and digital rectal examination. OBJECTIVE: The aim of this study was to investigate the prevalence of, and factors associated with, prostate examination among men aged 45 or older. DESIGN AND SETTING: Cross-sectional population-based study developed in the city of Rio Grande (RS), Brazil. METHODS: The outcome of interest was a history of prostate examination (prostate-specific antigen testing or digital rectal examination). The following independent variables were analyzed: age group, skin color, marital status, schooling, economic level, leisure-time physical activity, smoking habits, excessive alcohol consumption, overweight, health insurance, visits to the doctor during the preceding year, hypertension and diabetes. After a two-stage sampling process, the final sample consisted of 281 male individuals. RESULTS: The prevalence of a history of prostate-specific antigen testing or digital rectal examination was 68.3% (95% confidence interval (CI): 62.2 to 74.5). The highest prevalence rates were observed among men aged 70 years or older (88%) and the lowest among smokers (36%). The following characteristics were found to be associated with the outcome: advanced age; marital status other than single; more schooling and higher economic status; practicing physical activity; non-smoking habits; overweight; having health insurance; and having visited a doctor during the preceding year. CONCLUSION: Approximately two thirds of the study population had been screened for prostate examination, mostly older individuals, with higher socioeconomic status and a healthier lifestyle.

PURPOSE: Circulating microRNAs (miRNAs) have been shown to have the potential as noninvasive diagnosis biomarkers in several types of cancers, including prostate cancer (PCa). Urine-based miRNA biomarkers have been researched as an alternative tool in PCa diagnosis. However, few studies have performed miRNA detection in urine samples from PCa patients, as well as low numbers of miRNAs have been assayed, and there is a lack of standard strategies for validation. In this context, we conducted an in-depth literature review focusing on miRNAs isolated from urine samples that may contribute to the diagnosis of PCa. METHODS: A systematic review was performed searching the PubMed, Lilacs and Cochrane Library databases for articles focused on the value of significantly deregulated miRNAs as biomarkers in PCa patients. RESULTS: Only 18 primary manuscripts were included in this review, according to the search criteria. Our results suggest that miR-21-5p, miR-141-3p, miR-375 and miR-574-3p should be considered as potential urinary biomarkers for the diagnosis of PCa. CONCLUSION: These results suggested that large-scale prospective studies are still needed to validate our findings, using standardized protocols for analysis.

The aim of this study was to identify and analyze meanings attributed to practices related to prostate cancer prevention among men. A qualitative methodology was employed, with semi-structured interviews being conducted with 21 men in the city of Vitoria da Conquista, Bahia, between July and August of 2017. Data analysis was based on a dialectical hermeneutic approach. We found that practices related to prostate cancer prevention were based on scarce information and permeated by a sense of fear of the disease, which was thought of as a death sentence. Additionally, these feelings were compounded by the repercussions of rectal examination, perceived as a violation of one's masculinity. We were able to observe that practices devised to prevent prostate cancer reflect the repercussions of conceptions of masculinity regarding men's health care, where manliness and toughness can be susceptible by the touch.
El objetivo del estudio fue identificar y analizar los sentidos atribuidos por hombres a las prácticas relacionadas con la prevención del cáncer de próstata. Se realizó un estudio cualitativo, con entrevistas semiestructuradas, en el que participaron 21 hombres del municipio de Vitória da Conquista, Bahía. El período de recopilación de información fue entre julio y agosto de 2017. El análisis de los datos se basó en los principios de la hermenéutica-dialéctica. Se percibió que las prácticas relacionadas con la prevención del cáncer de próstata se elaboran con escasa información y permeadas por sentidos que remiten al miedo a la enfermedad, asumida como una sentencia a la vida, y a las repercusiones del tacto rectal, asimilado como una violación de la condición masculina. Se constató que las prácticas elaboradas para prevenir el cáncer de próstata reflejan las implicancias de la masculinidad en el cuidado de la salud de los hombres y, sobre todo, que la dureza masculina puede sentirse interpelada a partir de un tacto.

ABSTRACT Purpose: Prostate cancer screening in the elderly is controversial. The Brazilian government and the National Cancer Institute (INCA) do not recommend systematic screening. Our purpose was to assess prevalence and aggressiveness of prostate cancer in men aged 70 years and above, on the first Latin American database to date. Materials and Methods: Cross-sectional study (n=17,571) from 231 municipalities, visited by Mobile Cancer Prevention Units of a prostate-specific antigen (PSA) based opportunistic screening program, between 2004 and 2007. The criteria for biopsy were: PSA>4.0ng/ml, or PSA 2.5-4.0ng/ml with free/total PSA ratio ≤15%, or suspicious digital rectal examination findings. The screened men were stratified in two age groups (45-69 years, and ≥70 years). These groups were compared regarding prostate cancer prevalence and aggressiveness criteria (PSA, Gleason score from biopsy and TNM staging). Results: The prevalence of prostate cancer found was 3.7%. When compared to men aged 45-69 years, individuals aged 70 years and above presented cancer prevalence about three times higher (prevalence ratio 2.9, p<0.01), and greater likelihood to present PSA level above 10.0ng/ml at diagnosis (odds ratio 2.63, p<0.01). The group of elderly men also presented prevalence of histologically aggressive disease (Gleason 8-10) 3.6 times higher (p<0.01), and 5-fold greater prevalence of metastases (PR 4.95, p<0.05). Conclusions: Prostate cancer screening in men aged over 70 may be relevant in Brazil, considering the absence of systematic screening, higher prevalence and higher probability of high-risk disease found in this age range of the population studied.

Objetivo Mundialmente, el cáncer de próstata es la segunda neoplasia maligna más frecuente en hombres a nivel mundial y la primera en Colombia. Se determinaron las características clínico-patológicas de los casos de cáncer de próstata diagnosticados en un hospital de la región caribe colombiana. Métodos Se realizó un estudio retrospectivo en la Facultad de Medicina de la Universidad de Cartagena, Colombia. Se analizaron las características clínicas y patológicas de todos los pacientes diagnosticados con cáncer de próstata en el Hospital Universitario del Caribe durante los años 2007 a 2014. Resultados Se documentaron 394 casos, con edad promedio de 71,13 años (DE ± 8,25). El puntaje de Gleason fue mayor o igual a 8 en el 31,7%. En biopsias hubo localización bilateral del tumor en un 73,5% y compromiso tumoral mayor al 40% del tejido en el 73,2% de los casos. En un 5,8% de los pacientes, hubo valores de PSA normales. Se dio una asociación estadísticamente significativa entre el PSA y el examen digital rectal (p = 0,0009), puntaje de Gleason (p < 0,0001) y porcentaje de compromiso tumoral en biopsias (p < 0,0012). La combinación PSA más examen digital rectal obtuvo una sensibilidad del 96%. Conclusiones Gran parte de los casos de cáncer de próstata se diagnostican en estadios avanzados. La mayor sensibilidad para el diagnóstico clínico la tiene el uso del PSA más el examen digital rectal, sin dejar de lado la experiencia clínica que permite diagnosticarlo aún con PSA o examen digital rectal normales. Esos hallazgos deben promover la educación de la población.
Objective Worldwide, prostate cancer is the second most common malignant neoplasm diagnosed in men, in Colombia is the most common. The objective was to determine clinical and histopathological characteristics based upon the cases of prostate cancer diagnosed in a hospital of the Colombian Caribbean coast. Methods A retrospective study was conducted in the Faculty of Medicine at the University of Cartagena, Colombia. Clinical and pathological characteristics were analyzed in all patients diagnosed with prostate cancer at the Hospital Universitario del Caribe between January 2007 and December 2014. Results A total of 394 cases were documented. Mean presentation age was 71,1 years (SD ± 8,25). A Gleason score greater than 8 was reported in 31.7% of the cases. Biopsies showed bilateral tumor localization in 73.5% and percent tumor involvement greater than 40% in 73.2% of cases. 5.8% of patients presented with normal PSA values. A statistically significant difference was found between PSA and: digital rectal exam (p = 0.0009), Gleason Score (p < 0.0001) and percent tumor involvement in biopsies (p < 0.0012). PSA and digital rectal examination had a sensitivity of 96%. Conclusions A large proportion of prostate cancer cases are diagnosed in advanced stages. The highest sensitivity for the clinical diagnosis is made by the combined use of PSA and digital rectal examination, without ignoring the clinical experience that allows the diagnosis of cancer even in cases with normal PSA and/or digital rectal examination. These findings may increase awareness for the early diagnosis of the disease in the population.

RESUMEN El objetivo del estudio fue identificar y analizar los sentidos atribuidos por hombres a las prácticas relacionadas con la prevención del cáncer de próstata. Se realizó un estudio cualitativo, con entrevistas semiestructuradas, en el que participaron 21 hombres del municipio de Vitória da Conquista, Bahía. El período de recopilación de información fue entre julio y agosto de 2017. El análisis de los datos se basó en los principios de la hermenéutica-dialéctica. Se percibió que las prácticas relacionadas con la prevención del cáncer de próstata se elaboran con escasa información y permeadas por sentidos que remiten al miedo a la enfermedad, asumida como una sentencia a la vida, y a las repercusiones del tacto rectal, asimilado como una violación de la condición masculina. Se constató que las prácticas elaboradas para prevenir el cáncer de próstata reflejan las implicancias de la masculinidad en el cuidado de la salud de los hombres y, sobre todo, que la dureza masculina puede sentirse interpelada a partir de un tacto.
ABSTRACT The aim of this study was to identify and analyze meanings attributed to practices related to prostate cancer prevention among men. A qualitative methodology was employed, with semi-structured interviews being conducted with 21 men in the city of Vitoria da Conquista, Bahia, between July and August of 2017. Data analysis was based on a dialectical hermeneutic approach. We found that practices related to prostate cancer prevention were based on scarce information and permeated by a sense of fear of the disease, which was thought of as a death sentence. Additionally, these feelings were compounded by the repercussions of rectal examination, perceived as a violation of one's masculinity. We were able to observe that practices devised to prevent prostate cancer reflect the repercussions of conceptions of masculinity regarding men's health care, where manliness and toughness can be susceptible by the touch.

BACKGROUND: Digital rectal examination (DRE) is one of the most common strategies for prostate cancer early detection. However, the use for screening purposes has a controversial benefit and potential harms can occur due to false-positive results, overdiagnosis and overtreatment. The objective of this study is to calculate the prevalence and identify factors associated with the receipt of DRE in Brazilian men. METHODS: We selected men older than 40 from a nationwide population-based survey (13,625 individuals) excluding those with prostate cancer diagnosis. Information was extracted from the most recent database of the Brazilian National Health Survey (PNS 2013). Statistical analysis was carried out to calculate incidence rate ratios, with 95% confidence intervals and p values, through multivariate analysis with Poisson regression and robust variance. RESULTS: Men having private health insurance (63.3%; CI = 60.5-66.0) presented higher prevalence of DRE than those in the public health system (41.6%; CI = 39.8-43.4). The results show a positive association between DRE and men having private health insurance, aged 60-69, living with a spouse, never smokers, and living in urban areas. Among public health services users, this positive association was observed among men aged 70-79, living with a spouse, having bad/very bad health self-perception, abstainers, ex-smokers, with undergraduate studies, presenting four or more comorbidities, and residing in urban areas. CONCLUSIONS: Prostate cancer screening with DRE is quite frequent in Brazil, specially among men with private health plans and better access to health services, healthier lifestyle and at more advanced ages, characteristics which increase the risk of overdiagnosis and overtreatment.

Objetivo: Descrever o conhecimento, o comportamento e as práticas em relação ao câncer de próstata em adultos. Métodos: Estudo quantitativo, realizado com 130 homens. A coleta de dados ocorreu no primeiro semestre de 2015, por meio do Modelo de Crenças em Saúde. Resultados: Embora relatem conhecimento sobre o câncer, 30% realizam a dosagem do Antígeno Prostático Específico e 17,6% o exame de toque retal anualmente. A maioria percebe a susceptibilidade e a severidade do câncer e acredita que é capaz de fazer algo por si mesmo, beneficiando-se com esses cuidados. Quanto às barreiras, 16,9% apresentaram comportamento não preventivo. Conclusão: O medo da dor, a vergonha e a falta de coragem para realizar o exame constituem barreiras a esses indivíduos. A equipe de saúde deve oportunizar abordagens considerando esses aspectos, utilizando estratégias que ampliem o acesso dos homens ao serviço de saúde e estimulem a prática do autocuidado
Objective: The study's purpose has benn to describe the knowledge, behavior and health practices regarding the prostate cancer in adults. Methods: It is a cross-sectional and descriptive study with a quantitative approach, which had 130 participating men. Data collection took place from March to April 2015, using the Health Belief Model. Results: Although they report having knowledge about cancer, only 30% had done the prostate-specific antigen dosage and 17.6% the rectal examination annually. Most comprehend the susceptibility and severity of this cancer, and believe that they are capable of doing something for themselves and benefiting from such care. Regarding the barriers, 16.9% had non-preventive behavior. Conclusion: Fear of pain, shame, and lack of courage to take the exam are barriers to these individuals. The health team should opportunistically approach these aspects by using strategies that increase men's access to health care and encourage self-care practices

El cáncer de próstata es un problema de salud pública a nivel mundial, el cual clásicamente se sospecha por alteració en el antígeno prostático (PSA) y/o tacto rectal (TR) y se confirma con biopsia prostática. No obstante, existen otros marcadores como la densidad del PSA (DPSA) que se emplean para determinar la necesidad de una biopsia. Objetivo: Verificar la utilidad actual de la DPSA como herramienta diagnóstica para cáncer de próstata. Métodos: Es un estudio descriptivo, prospectivo, tipo transversal, la selección de la muestra se efectuó mediante muestreo no probabilístico intencional, quedando integrada por el número de pacientes con criterios de biopsia prostática que acudieron al Servicio de Urología del Hospital Universitario de Caracas durante los meses de junio -julio del 2014. El análisis estadístico se realizó con el programa SPSS/PC versión 25.0. Resultados: El estudio estuvo conformado por 100 pacientes con edad media de 65±7,7. La tasa de detección de cáncer de próstata fue del 38% tomando en cuenta los criterios convencionales (PSA y TR), sin embargo, cuando el criterio es la DPSA se redujo el número de pacientes a 33 de los cuales el 69,7% (n 23) presentaron cáncer de próstata. Conclusión: La DPSA es una herramienta útil para ser usada como criterio para la realización de biopsia prostática con una tasa de detección general del 60,52% lo cual supera por si sola a los métodos de despistaje convencionales como lo son el valor del PSA y el tacto rectal(AU)
Prostate cancer is a public health problem worldwide, which is classically suspected due to alteration in prostatic antigen (PSA) and / or rectal examination (RE) and confirmed by prostate biopsy. However, there are other markers such as PSA density (DPSA) that are used to determine the need for a biopsy. Objective: To verify the actual usefulness of PSA density as a diagnostic tool for prostate cancer. Methods: Prospective, descriptive, cross-sectional, the selection of the sample was performed by intentional nonprobabilistic sampling, being composed of the number of patients with prostate biopsy criteria who attended the department of urology at University Hospital in Caracas during the months of june -july 2014. Statistical analysis was performed using SPSS / PC Version 25.0 program. Descriptive statistics were used. Results: îe study consisted of 100 patients with a mean age of 65 ± 7.7. îe detection rate of prostate cancer was 38% taking into account the conventional criteria (PSA and RE), however when the criterion is the DPSA the number of patients was reduced to 33 of which 69.7% (n 23) prostate cancer. Conclusion: îe DPSA is a useful tool to be used as a criterion for performing a prostate biopsy overall detection rate of 60.52% which exceeds by itself to conventional screening methods such as the value of PSA and DRE(AU)

ABSTRACT Purpose To identify how the most frequently used parameters in daily clinical practice diagnosing bladder outlet obstruction (BOO) due to benign prostate hyperplasia (BPH) correlate to each other. Materials and methods The study included 452 patients with lower urinary tract symptoms (LUTS) of the UNICAMP urology outpatient clinic of LUTS. Inclusion criteria: patients with BOO due to BPH who agreed to participate in the study. Exclusion criteria: patients with urinary tract infection, neurological diseases that compromised the lower urinary tract, prior prostatic surgery, radiotherapy or urethral stenosis. Patient assessment: history, international prostate symptoms score (IPSS), nocturnal quality of life score (NQoL) questionnaires, physical and digital rectal examination (DRE), PSA, transabdominal ultrasound with intravesical prostate protrusion (IPP), post-mictional residue and free uroflowmetry. Results There was no strong Spearman correlation among the studied variables. The only moderate correlations occurred between IPSS and NQoL (p <0001; c=0.56) and between IPP and prostate volume (p <0001; c=0.57). Weak correlations between IPP and post-mictional residue (p <0001; c=0.31) and free uroflowmetry (p <0001; c=-0.26); and between IPSS and free uroflowmetry (p <0001, c=-0.21) were observed. Conclusion In this study, we found moderate, weak, very weak and absent correlation among the various parameters used in the diagnosis and management of BOO due to BPH. As the value of these tools is variable, the creation of a logical and objective algorithm was not possible and the treatment is based on the interpretation of clinical symptoms.

Background: Prostate cancer is the second most incident of the male population in Brazil. The aim of this study is to analyze the frequency of risk factors associated to the evolution of the prostate cancer and the impact of conducting examinations in the age range (55-69 years old), in assisting health professionals to manage and prevent the disease. Methods: A case-control study was performed on patients from 2011 to 2016 in Criciúma SC, Brazil. The sample was divided into two groups, one with biopsy for prostate adenocarcinoma (case; n = 124) and the other with a negative biopsy (control; n = 251). The following variables were compared between the two groups: age, family history of prostate cancer, prostate specific antigen, and altered digital rectal examination. Results: In the case group, ranging between 55-69 years old, there was a significant higher of altered digital rectal examination (p < 0.001, odds ratio 15.5 and positive predictive value 91.3%), prostate-specific antigen ≥ 4 ng/mL (p < 0.001, odds ratio 7.02 and positive predictive value 56.2%) and when both exams were altered (p < 0.001, odds ratio was 19.63 and the positive predictive value was 90.5%). Conclusion: This findings show that, mainly between 55-69 years old, there is a significant correlation between positive biopsy, altered digital rectal examination, and PSA ≥ 4 ng/mL (AU)
Objetivo: O câncer de próstata é o segundo mais incidente na população masculina no Brasil. O objetivo do estudo é analisar a frequência dos fatores de risco associados ao desenvolvimento do câncer de próstata e o impacto da realização de exames na faixa etária de rastreamento (55-69 anos), auxiliando os profissionais de saúde no manejo e prevenção da doença. Método: Foi realizado um estudo caso-controle no período de 2011 a 2016 em Criciúma SC, Brasil. A amostra foi dividida em dois grupos, um com biópsia de adenocarcinoma de próstata (casos; n = 124) e outro com biópsia negativa (controles; n = 251). Entre ambos os grupos, foram comparadas as variáveis: idade, história familiar de câncer de próstata, antígeno prostático específico e toque retal alterado. Resultados:No grupo dos casos, na faixa etária entre 55-69 anos, ocorreu maior significância de toque retal alterado (p < 0,001; odds ratio 15.5 e valor preditivo positivo 91,3%), antígeno prostático específico ≥ 4 ng/mL (p < 0,001; odds ratio 7.02 e valor preditivo positivo 56,2%) e quando os dois exames estavam alterados (p < 0,001; odds ratio 19.63 e valor preditivo positivo 90,5%). Conclusão: Há evidências, principalmente entre 55-69 anos, de maior correlação de biópsia positiva, toque retal alterado e PSA ≥ 4 ng/mL (AU)
