Intervención educativa sobre el examen y autoexamen de próstata en pacientes mayores de 45 años / Educational Intervention on Prostate Examination and Self-Examination in Patients older than 45

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)

Watch and wait, worth It?

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)

Diagnóstico ecográfico de la neoplasia prostática y su relación histológica / Ultrasound diagnosis of prostatic neoplasia and histological relationship

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)

Patients' reactions to digital rectal examination of the prostate

Background:Digital rectal examination (DRE) of the prostate is a simple, fast, cost effective and safe procedure, however, because of previous painful experience, some men may refuse it. Other negative factors include cultural barriers, fear of discovering cancer and embarrassments. However, some men accept DRE because of their symptoms and wishes to contribute to science. The aim of this study was to examine how previous experience of DRE could influence a repeat and to further evaluate their impression before and after DRE including pain score. Patients and Methods:We evaluated one hundred patients who met the inclusion criteria using a structured questionnaire that detailed information on patients biodata, their previous DRE experiences, expectations before and reactions after a repeat. Pain score was also examined using visual analog scale of 0 to 10. Data were collated and analysed using statistical package for social sciences (SPSS) version 20.0. P-value was set at <0.05. Results:Mean age of patients was 64.88±7.53 years ranging from 46 to 82 years. Forty five percent of them complained of pain from previous DRE while 55% reported no pain. Forty one percent of the men anticipated pain before this present procedure but only 8% of them reported that it was painful and humiliating after the procedure. Fifty nine percent had good impression before DRE and after the procedure 92% reported good impression. All patients expressed their willingness to repeat DRE in future if need be and to encourage friends who may need DRE evaluation of their condition. Mean pain score was 0.59± 1.349 (0 ­ 9). Conclusion:Patients previous experience of DRE could negatively influence a repeat procedure because of pain, improper counseling apart from some cultural barriers. DRE in the hands of Urologists has been better tolerated than other clinicians. This calls for proper exposure of medical students to this procedure and need for continuous medical education for other clinicians for skills improvement.

Metabolomic Profile in Patients with Malignant Disturbances of the Prostate: An Experimental Approach / Perfil metabolómico en pacientes con alteraciones malignas de la próstata: Un enfoque experimental

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.

Fatores associados à masculinidade no diagnóstico precoce do câncer de próstata: revisão narrativa / Factors associated with masculinity in the early diagnosis of prostate cancer: a narrative review

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)

Prostate examination among adult and elderly subjects in southern Brazil: a cross-sectional population-based study

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.

Prostate cancer screening among elderly men in Brazil: should we diagnose or not?

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.

Presentación clínico-patológica del adenocarcinoma prostático en un Hospital de tercer nivel en Colombia / Clinical-pathological Presentation of Prostatic Adenocarcinoma in a Tertiary Hospital in Colombia

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.

"Afectados por el tacto": sentidos atribuidos por hombres a las prácticas de prevención del cáncer de próstata / "Affected by the touch": Meanings attributed to prostate cancer prevention practices among men

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.

Accuracy of digital rectal examination to diagnose prostate cancer confirmed by needle biopsy reports: A 3­year hospital-based study

Background: Digital rectal examination (DRE) is an indispensable tool for provisional diagnosis of prostate diseases. When abnormal prostate examination findings are elicited, a diagnosis of prostate cancer (Pca) is usually entertained and further tests to confirm or rule out the presence of Pca demands histological examination of biopsied tissue. A combination of DRE findings and serum PSA increases the predictive value for Pca diagnosis. In this study, we evaluated the degree of accuracy of DRE to diagnose Pca confirmed by histology reports of biopsy specimens.Materials and Methods: Two hundred and six (206) patients were studied over a period of three years. Information retrieved from their case notes were entered into a well-structured protocol for management of prostatic diseases. Analysis of variables collated was performed with the statistical package for the social sciences (SPSS) version 20.0. Frequency table was used to analyze categorical variables while descriptive statistics was used for continuous variables. Level of significance was set at P<.05.Results: 206 patients were studied with mean age of 68.23±8.71 years ranging from 48 to 91 years. Men in the Pca group were older than those in the BPH group. Abnormal DRE was associated with high grade tumours, and high level of aggressive tumour characteristics by WHO grade group standard.Conclusion: DRE has a high level of accuracy in predicting a diagnosis of Pca which was confirmed by histology reports especially in prostates with abnormal findings

Conhecimento, comportamento e práticas em saúde do homem em relação ao câncer de próstata / Knowledge, behaviour and health practices of men concerning the prostate cancer / Conocimiento, comportamiento y práctica en salud del hombre en relación con cáncer de próstata

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

Resultados: Aunque reportan conocimiento sobre el cáncer, el 30% realiza la dosificación del Antígeno Prostático y el 17,6% el examen de tacto anual. La mayoría percibe la susceptibilidad y la severidad del cáncer y cree que es capaz de hacer algo por sí mismo y beneficiarse con esos cuidados. En cuanto a las barreras, el 16,9% presentó comportamiento no preventivo. Conclusión: El miedo al dolor, la vergüenza y la falta de coraje para realizar el examen constituyen barreras a esos individuos. El equipo de salud debe oportunizar enfoques considerando estos aspectos, utilizando estrategias que amplíen el acceso al servicio de salud y estimulen la práctica del autocuidado

Densidad del antígeno prostático en el diagnóstico de cáncer de próstata / Prostate antigen density in the diagnosis of prostate cancer

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: e study consisted of 100 patients with a mean age of 65 ± 7.7. e 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: e 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)

Correlation of tools for objective evaluation of infravesical obstruction of men with lower urinary tract symptoms

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.

Prostate cancer profiles and associated factors in Criciúma ­ Santa Catarina, Brazil

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)

Can expressed prostatic secretions affect prostate biopsy decision of urologist?

ABSTRACT Objectives: To evaluate the frequency of NIH category IV prostatitis, and the use of expressed prostatic secretions tests in an effort to improve the reliability of prostate specific antigen as an indicator, to avoid unnecessary prostate biopsy. Materials and Methods: 178 expressed prostatic secretion positive patients with serum prostate specific antigen levels of ≥ 2.5 ng / mL were included in present prospective study. The diagnostic evaluation included detailed history and physical examination, digital rectal examination, urine analysis, urine culture, and expressed prostatic secretions tests. Transrectal ultrasonography was used both to measure prostate volume and conduct 12 core prostate biopsy. Results: The prevalence of NIH category IV prostatitis was 36.9% (178 / 482) in our population of men. In our study patients (n: 178) prostate biopsy results were classified as; 66 prostatitis, 81 BPH, and 31 Pca. In asymptomatic prostatitis group, expressed prostatic secretion mean leucocyte ratio was higher compared to other two groups (p < 0.0001). The relation between number of expressed prostatic secretion leucocytes and prostatitis, benign prostate hyperplasia, and prostate cancer is analyzed. If 16 is taken as the cut of number for leucocyte presence, its sensitivity is 0.92 (AUC = 0.78 p = 0.01). Conclusions: The number of leucocytes in expressed prostatic secretion is higher in the chronic prostatitis group. If the leukocyte presence of 16 and above is taken as the cut off point, the sensitivity becomes 0.92 (AUC = 0.78). We firmly believe that our new cut off value may be used as to aid prostate specific antigen and derivates while giving biopsy decision.

The TNM 8th edition: Validation of the proposal for organ - confined (pT2) prostate cancer

ABSTRACT Purpose: The 8th edition of the TNM has been updated and improved in order to ensure a high degree of clinical relevance. A major change in prostate includes pathologically organ - confined disease to be considered pT2 and no longer subclassified by extent of involvement or laterality. The aim of this study was to validate this major change. Materials and Methods: Prostates were step - sectioned from 196 patients submitted to radical prostatectomy with organ confined disease (pT2) and negative surgical margins. Tumor extent was evaluated by a semiquantitative point count method. The dominant nodule extent was recorded as the maximal number of positive points of the largest single focus of cancer from the quadrants. Laterality was considered as either total tumor extent (Group 1) or index tumor extent (Group 2). Time to biochemical recurrence was analyzed with the Kaplan - Meier product limit analysis and prediction of shorter time to biochemical recurrence with Cox proportional hazards model. Results: In Group 1, 43 / 196 (21.9%) tumors were unilateral and 153 / 196 (78.1%) bilateral and in Group 2, 156 / 196 (79.6%) tumors were unilateral and 40 / 196 (20.4%) bilateral. In both groups, comparing unilateral vs bilateral tumors, there was no significant clinicopathological difference, and no significant association with time as well as prediction of shorter time to biochemical recurrence following surgery. Conclusions: Pathologic sub - staging of organ confined disease does not convey prognostic information either considering laterality as total tumor extent or index tumor extent. Furthermore, no correlation exists between digital rectal examination and pathologic stage.

A experiência do médico examinador tem influência na avaliação do tônus anal em comparação à manometria anorretal? / Is the physician expertise in digital rectal examination of value in detecting anal tone in comparison to anorectal manometry?

ABSTRACT BACKGROUND: Digital rectal examination (DRE) is part of the physical examination, is also essential for the colorectal surgeon evaluation. A good DRE offers precious information related to the patient's complaints, which will help in decision making. It is simple, quick and minimally invasive. In many centers around the world, the DRE is still the only method to evaluate the anal sphincter prior to patient's management. On the other hand, anorectal manometry (ARM) is the main method for objective functional evaluation of anal sphincter pressures. The discrepancy of DRE depending on the examiner to determine sphincter tonus in comparison to ARM motivated this study. OBJECTIVE: To compare the DRE performed by proficient and non-experienced examiners to sphincter pressure parameters obtained at ARM, depending on examiners expertise. METHODS: Thirty-six consecutive patients with complaints of fecal incontinence or chronic constipation, from the anorectal physiology clinic of the University of São Paulo School of Medicine, were prospectively included. Each patient underwent ARM and DRE performed by two senior colorectal surgeons and one junior colorectal surgeon prior to the ARM. Patient's history was blinded for the examiner's knowledge, also the impressions of each examiner were blinded from the others. For the DRE rest and squeeze pressures were classified by an objective scale (DRE scoring system) that was compared to the parameters of the ARM for the analysis. The results obtained at the ARM were compared to the DRE performed by the seniors and the junior colorectal surgeons. STATISTICAL ANALYSIS: Descriptive analysis was performed for all parameters. For the rest and squeeze pressures the Gamma index was used for the comparison between the DRE and ARM, which varied from 0 to 1. The closer to 1 the better was the agreement. RESULTS: The mean age was 48 years old and 55.5% of patients were female. The agreement of rest anal pressures between the ARM and the DRE performed by the senior proficient examiners was 0.7 (CI 95%; 0.32-1.0), while for the junior non-experienced examiner was 0.52 (CI 95%; 0.09-0.96). The agreement of squeeze pressures was 0.96 (CI 95%; 0.87-1.0) for the seniors and 0.52 (CI 95%; 0.16-0.89) for the junior examiner. CONCLUSION: More experienced colorectal surgeons used to DRE had a more significant agreement with the ARM, thereafter would have more appropriate therapeutic management to patients with sphincter functional problems. ARM, therefore, persists as an important exam to objectively evaluate the sphincter complex, justifying its utility in the clinical practice.

RESUMO CONTEXTO: Exame anorretal digital (EAD) faz parte do exame físico, também é essencial para a avaliação do cirurgião colorretal. Um bom EAD oferece informações preciosas relacionadas às queixas do paciente, que auxiliam na tomada de decisões. Sua realização é simples, rápida e minimamente invasiva. Em diversos centros ao redor do mundo, o toque retal ainda é o único método para avaliar o esfíncter anal antes do tratamento. Por outro lado, a manometria anorretal (MAR) é o principal método para avaliação funcional objetiva das pressões esfincterianas. A discrepância entre o EAD, dependendo do examinador para determinar o tônus esfincteriano em comparação à MAR motivou este estudo. OBJETIVO: Comparar o EAD com os parâmetros de pressão esfincteriana obtidos na MAR, dependendo da experiência dos examinadores. MÉTODOS: Trinta e seis pacientes consecutivos com queixas de incontinência fecal ou constipação crônica, do ambulatório de Fisiologia Anorretal da Faculdade de Medicina da Universidade de São Paulo, foram prospectivamente incluídos. Cada paciente foi submetido a MAR e EAD realizados por dois cirurgiões colorretais seniores e um júnior antes da MAR. A história dos pacientes propositalmente omitida dos examinadores, e os resultados de cada examinador foram cegos dos demais. Para o EAD, as pressões de repouso e contração foram classificadas por uma escala objetiva (EAD Scoring System), realizada pelos examinadores seniores e pelo júnior em todos os pacientes, que foi comparada com os parâmetros da MAR para a análise. ANÁLISE ESTATÍSTICA: A análise descritiva foi feita para todos os parâmetros. Para as pressões de repouso e contração, o índice Gamma foi utilizado para a comparação entre o EAD e a MAR, que variou de 0 a 1. Quanto mais próximo de 1 melhor a concordância entre os dois métodos de avaliação. RESULTADOS: A idade média foi de 48 anos e 55,5% dos pacientes eram do sexo feminino. A concordância das pressões anais de repouso entre a MAR e o EAD realizadas pelos examinadores seniores, proficientes, foi de 0,7 (IC 95%; 0,32-1,0), enquanto para o examinador júnior, menos experiente, foi de 0,52 (IC95%; 0,09-0,96). A concordância das pressões de contração foi de 0,96 (IC 95%; 0,87-1,0) para os examinadores seniores e de 0,52 (IC 95%; 0,16-0,89) para o júnior. CONCLUSÃO: Cirurgiões colorretais mais experientes, o EAD teve concordância mais significativa com a MAR, o que poderia levar a um manejo terapêutico mais adequado aos pacientes portadores de doença anorretais funcionais. A manometria anorretal permanece, portanto, como método de avaliação objetiva da função esfincteriana.

Tamización poblacional para la detección temprana del cáncer de próstata: ¿Qué hemos aprendido en los últimos 10 años? / Population Screening for Early Detection of Prostate Cancer: ¿What have we Learned in the Last Decade?

Introducción Desde el inicio de la aplicación del cribado para cáncer de próstata basado en el antígeno prostático específico (PSA) hace aproximadamente dos décadas, la controversia sobre los beneficios y desventajas de su uso rutinario ha sido constante. La literatura médica cuenta con múltiples estudios que en ocasiones han revelado resultados contradictorios sobre los posibles beneficios de la tamización con PSA; la tasa de detección de cáncer de próstata indolente detectado parece ser alta y los estudios no demuestran de forma constante los beneficios en términos de reducción de la mortalidad cáncer específica o general. El propósito del presente artículo, es definir a la luz de la literatura médica reciente, la utilidad a nivel poblacional del cribado para cáncer de próstata basado en el antígeno prostático específico. Materiales y métodos Se realizó una revisión en los buscadores Pubmed, Embase y Lilacs utilizando los términos MesH "Prostatic neoplasms," "early detection of cancer," "mass screening," "prostate specific antigen," "digital rectal examination," "Outcome assesment (Health care)." Se filtró la búsqueda hacia estudios ejecutados en humanos, y/o metanálisis y revisiones sistemáticas publicados durante los últimos 10 años. Los abstracts fueron valorados por el grupo de autores e incluidos para análisis según su aporte al objetivo principal del estudio. Algunas referencias adicionales fueron añadidas dada su importancia clínica e histórica. Resultados Se identificaron 23 referencias con la estrategia de búsqueda, se excluyeron del análisis 9 referencias por no aportar datos relevantes para el presente artículo. Se incluyeron para revisión un total de 14 artículos. Discusión La tamización para cáncer de próstata con base en el antígeno específico de próstata sérico es una estrategia que permite aumentar la tasa de detección temprana de cáncer, sin embargo, se asocia a una importante tasa de detección de cáncer de próstata indolente y de sobretratamiento. Los resultados de la literatura evaluada son contradictorios con respecto al efecto que tiene la tamización sobre la mortalidad específica por cáncer, algunos estudios han revelado una disminución de ese ítem en los pacientes sometidos a tamización para cáncer de próstata. Los datos también son contundentes en demostrar que las estrategias de tamización no han impactado la supervivencia general en los grupos estudiados. Se esperan resultados de estudios que incluyan el armamento de estrategias disponibles para estimar el riesgo de cáncer de próstata (imágenes y/o nuevos marcadores tumorales) con el fin de mejorar la relación riesgo/beneficio de la estrategia de cribado para cáncer de próstata. Conclusiones La tamización para cáncer de próstata debe ser una estrategia para la detección temprana del cáncer que se usa de forma consensuada con cada paciente y que debe adaptarse al riesgo individual; el paciente a quien se le aplica el cribado debe entender los potenciales riesgos y beneficios de esta estrategia ya que los datos disponibles no permiten demostrar con alto nivel de evidencia, un beneficio clínico traducido en términos de reducción en la mortalidad del cáncer específica o general.

Introduction In the last decade, the prostate-specific antigen based screening for prostate cancer have evoque a lot of controversies on the basis of his risk ­ benefit ratio; there are controversial data about the impact of this strategy in the male cancer specific and general mortality. The aim of this article is to show the most recent findings and to define the utility of the population screening for early detection of prostate cancer. Material and Methods A literature review was performed in PubMed, Embase and Lilacs using the MeSH terms: "Prostatic neoplasms," "early detection of cancer," "mass screening," "prostate specific antigen," "digital rectal examination" and "Outcome assesment (Health care)" which was limited to scientific articles published in the past 10 years. The abstracts were evaluated and excluded if they were not related to primary aim of this article. Some references were included given their clinical relevance. Results 23 articles were retrieved, and after reviewing the abstracts, 9 articles were excluded as they were not related to our primary aim. The analysis was performed in 14 articles. Discussion The prostate-specific antigen based population screening has been associated with an early diagnosis of prostate cancer even, in a non significative clinical stage, and consequent overtreatment. The literature which was evaluated have controvesial outcomes on the cancer-specific mortality, however none of the articles evaluated shown a significant impact in male general mortality. In the overcoming years, we expect the results of some investigations which includes additional tools for the screening of prostate cancer (multiparametric prostate resonance imaging, new tumoral markers), to improve the risk-benefit of this strategy. Conclusions The population prostate cancer screening should be made in well-informed patients and shared based decision process. The urologist and patient should to know the potential benefits and risks of this strategy, because there is not high grade level of evidence which supports a significant effect of this strategy in male general and cancer-specific mortality.

Nationwide Survey for Application of ROME IV Criteria and Clinical Practice for Functional Constipation in Children

BACKGROUND: This study aimed to investigate the awareness and application of ROME IV criteria for functional constipation (FC) in real-world practices and assessed differences between pediatric gastroenterologists (PGs) and general pediatricians. METHODS: A total of 239 (47.8%) out of 500 nationwide pediatricians answered a questionnaire for diagnosis and management of pediatric FC; 60 were PGs (75% of total PGs in Korea). RESULTS: A total of 16.6% of pediatricians were aware of the exact ROME IV criteria. Perianal examination and digital rectal examination were practiced less, with a higher tendency among PGs (P 6 months (63.8%) than 1-year were lactulose (59.1%), followed by polyethylene glycol (PEG) 4000 (17.7%), and probiotics (11.8%). Prescription priority significantly differed between PGs and general pediatricians; lactulose or PEG 4000 were most commonly prescribed by PGs (89.7%), and lactulose or probiotics (75.7%) were prescribed by general pediatricians (P < 0.001). For patients aged < 1-year, lactulose (41.6%) and changing formula (31.7%) were commonly prescribed. Most participants recommended diet modification, and PGs more frequently used defecation diary (P = 0.002). CONCLUSION: Discrepancies between actual practice and Rome IV criteria and between PGs and general pediatricians were observed. This survey may help construct practice guidelines and educational programs for pediatric FC.
