Resumo: A relação entre a atrofia inflamatória com a neoplasia intraepitelial alto grau e o carcinoma, é controversa. Tem sido sugerida uma relação topográfica e que o epitélio proliferativo da atrofia inflamatória possa progredir para neoplasia intraepitelial prostática alto grau (NIPAG) e/ou carcinoma (CA). O propósito do nosso estudo foi analisar em espécimes de prostatectomia radical uma possível relação topográfica entre estas lesões. Um total de 3186 quadrantes pertencentes a 100 prostatectomias radicais completamente representadas, foi analisado. Determinou-se a frequência de quadrantes mostrando: somente atrofia inflamatória (AI), AI+CA, AI+NIPAG, ou AI+NIPAG+CA. A extensão e a distância entre as lesões foram avaliadas através de um método semiquantitativo de contagem de pontos previamente descrito. Também foram analisados focos de atrofia completa ou parcial sem inflamação. Os métodos estatísticos empregados foram os testes de Kruskal-Wallis e Mann-Whitney, e o coeficiente de correlação de Spearman. A média dos quadrantes exibindo somente AI, AI+CA, AI+NIPAG, e AI+NIPAG+CA foi 3.29, 2.51, 0.77, e 0.44; e a amplitude (0-21), (0-11), (0-6), (0-4), respectivamente (p<0.01). A maioria dos focos de AI estavam a uma distância >5mm dos focos de NIPAG e CA. Não houve correlação significativa entre a extensão da AI (p= 0.64, r= 0.05) com a extensão da NIPAG. Houve uma significativa correlação negativa entre a extensão da AI (p=0.01, r=-0.27) com a extensão do CA. Resultados similares foram encontrados considerando focos de atrofia com ou sem inflamação. Focos de atrofia parcial não evidenciaram inflamação crônica inespecífica. Nosso estudo não evidenciou associação topográfica significativa entre AI, NIPAG e/ou CA
Abstract: It is controversial whether there is any relationship of proliferative inflammatory atrophy (PIA) to high-grade prostatic intraepithelial neoplasia (HGPIN) and cancer (CA). It has been suggested a topographic relation and a potential of the proliferative epithelium in PIA to progress to HGPIN and/or CA. The aim of this study was to analyze in radical prostatectomies a possible topographic relation of the lesions. A total of 3186 quadrants from 100 whole-mount consecutive surgical specimens was examined. The frequency of quadrants showing: only PIA, PIA+CA, PIA+HGPIN, or PIA+HGPIN+CA was determined. Extent and distance between the lesions were evaluated by a semiquantitative point-count method previously described. We also studied foci with partial or complete atrophy without inflammation. The statistical methods included the Kruskal-Wallis and the Mann-Whitney tests and the Spearman correlation coefficient. The mean (range) of quadrants showing only PIA, PIA+CA, PIA+HGPIN, and PIA+HGPIN+CA was 3.29 (0-21), 2.51 (0-11), 0.77 (0-6), and 0.44 (0-4), respectively (p<0.01). Most of the foci of PIA were significantly located in a distance >5mm than <5mm from HGPIN or CA. There was no significant correlation between extent of PIA (p=0.64, r=0.05) with extent of HGPIN. There was a significant negative correlation of extent of PIA (p=0.01, r=-0.27) with extent of CA. Similar results were found considering foci either with or without inflammation. Chronic inespecific inflammation was not seen in foci of partial atrophy. A topographic relation of PIA to HGPIN and/or CA was not supported by our study

Full textIntrodução: Na avaliação do câncer de próstata localizado, a gradação histológica de Gleason combinada à dosagem do PSA são os principais fatores prognósticos. Recentemente, autores têm sugerido que a aferição da quantidade de câncer na biopsia tem valor preditivo aos achados patológicos adversos na peça cirúrgica e ao risco de recorrência bioquímica. Objetivo: Avaliar a associação do percentual de fragmentos acometidos por câncer na biopsia prostática com a extensão tumoral na peça cirúrgica. Métodos: Estudo retrospectivo de 159 pacientes submetidos à prostatectomia radical. Coletado dados clínicos e patológicos. Análise estatística com os testes T de Student, qui-quadradro, e uma regressão logística múltipla avaliaram a associação do percentual de fragmentos acometidos com a extensão tumoral e o seu valor preditivo. Resultados: A avaliação histopatológica revelou 20,8% de pacientes com doença extraprostática, 8,2% com invasão das vesículas seminais e 35,8% com margens comprometidas. O percentual de fragmentos acometidos foi estratificado em três grupos: menor que 34%, 34 a 50%, e maior que 50%, e em cada grupo foi estudada a incidência de extensão extraprostática, invasão das vesículas seminais e comprometimento das margens cirúrgicas, sendo verificado que com o aumento do percentual de fragmentos acometidos ocorreu também um aumento nas alterações patológicas identificadas. Conclusões: Concluiu-se que o percentual de fragmentos acometidos na biópsia é um importante fator preditor do estágio patológico no espécime da prostatectomia radical, e deve ser utilizado na prática diária, em conjunto com os outros parâmetros já consagrados, para oferecer uma melhor condução prognóstica e terapêutica aos pacientes

Full textObjective: To investigate the presence of benign prostatic hyperplasia and/or malignant neoplasm of the prostate in men over 50 years of age, living in the Metropolitan Area of Porto Alegre, who enrolled in a voluntary screening program for prostatic diseases. Material and Method 1,227 men were assessed, 1,212 over 50, who came to the Urology Outpatient Unit at Hospital de Clínicas de Porto Alegre (RS/Brazil), during two events called "Prostate Fortnight", at the invitation of the usual social communications media. The assessment was performed in two visits: at the first visit, the patients answered the I PSS questionnaire, their history was taken, digital rectal examination, PSA, and urofluxommetry was performed; at the second visit treatment or complementary investigation as indicated was performed. The results were analyzed using the linear association test of Mantel-Haenszel. Results Most patients were aged 50 to 64, mean age 61.7. As to IPSS, 40.1 % of the patients presented a score of 8-19, and 24.9%, 20-35. Regarding quality of life,59.9% of the patients were elassified as having intermediate QL. Only 22.4% of the patients had prostates with a weight eonsidered normal «20g); in 47.3% of the total number of patients, prostatie nodules were found. The PSA dosage was altered in 19,4% of the patients when the PSA values were not adjusted for age, and only 14.7% of them presented an abnormal PSA when the values were adjusted for age. Urofluxommetry showed that 62.3% of the patients have alteration of the maximun flow rate. Ali these variables presented a linear assoeiation significant for age. 230 biopsies were indicated and 149 performed (12.2% of the total number of patients). The anatomopathological exam showed adenocareinoma in 23 patients (1.9% of the total), ali of them with a high PSA; 19 of these had presented ehanges at digital reetal examination. Conclusion In the population studied, the age of the patients presented a significant linear assoeiation with the IPSS and QL seores, weight and prostatie nodules, PSA and Qmax, showing that ali variables beeome worse with age. The IPSS showed 65% of the patients with moderate to severe urinary symptoms, and a significant linear assoeiation with the QL seore. A signifieant linear assoeiation was also found between prostatie weight and IPSS and QL seores. At digital rectal examination, 47.3% of the patients presented with prostatie nodules. The PSA value was altered in 19.4% when it was not adjusted for age and in 14,7% when the values were adjusted for age. The results of Qmax in urofluxommetry showed ehanges in 62.3% of the patients and there was a significant linear association between the diminished value of Qmax and the IPSS, QL and prostatie weightscores. In the population studied, 23 patients (1.9% of the total) had adenoeareinoma of the prostate and 65% had symptoms of prostatism.

Full textVEGF ejerce sus funciones principalmente en las células endoteliales a través de dos receptores con acción tirosín quinasa FLK/ KDR (VEGFR2) y Flt-1( VEGFR2).
En el cáncer prostático se ha demostrado un aumento de la densidad vascular o angiogénesis en el carcinoma respecto al tejido normal, correlacionándose con otros marcadores pronósticos del cáncer prostático ya conocidos. Nuestro estudio ha demostrado un incremento de la densidad vascular y de la expresión de los factores angiogénicos VEGF y bFGF, y de los receptores FLK/ KDR y Flt-1 en la lesión precursora del cáncer de prostático, la neoplasia intraepitelial de alto grado (PINAG). Además, el aumento de la angiogénesis se ha correlacionado con los adenocarninomas prostáticos de alto grado de Gleason y estadios avanzados (pT3).
El aumento de la angiogénesis y la expresión de los factores angiogénicos y de sus receptores en la neoplasia intraepitelial de alto grado, apoya un papel de esta lesión como precursora en el cáncer prostático, y plantea su posible aplicación en biopsia por aguja en la próstata como marcador pronóstico adicional del adenocarcinoma prostático.
The process of angiogenesis is necessary for tumor growth beyond 2-3mm and for the development of metastasis. Vascular endothelial growth factor (VEGF) is the most potent angiogenic factor so far detected, and can function synergistically with Basic Fibroblastic growth factor (bFGF) inducing angiogenesis. VEGF acts upon binding to two tyrosine kinase receptors FLK/ KDR (VEGFR2) and Flt-1 (VEGFR2).
In prostate cancer the study of angiogenesis has revealed an increase in the microvessels density in the carcinoma compared to normal prostatic glands, and its has been correlated with pathological stage. Our results demostrated an increase in the vessels density and in the expression of the angiogenic factors VEGF and bFGF, and the receptors FLK/ KDR and Flt-1 in the prostatic intraepithelial neoplasia. Interestingly, angiogenesis also correlated with tumor grade and pathological stage (pT3).
The increased angiogenesis and expression of the angiogenic factors and their receptors in the prostatic intraepithelial neoplasia, support a premalignant role for this lesion, and suggest their application in prostatic core-biopsies as an additional prognostic factor in prostatic cancer.

Full textDogs are the only animal other than man to develop prostate cancer, prostatic intraepithelial neoplasia (PIN) and benign prostatic hyperplasia (HPB) spontaneously, allowing the comparison between benign and malignat affections of prostate. Malignant stem cells among the basal cell layer of the prostate are believed to play an important role in the failure of androgen-ablation therapy that occurs in most advanced prostate cancer. The goal of this study was to characterize the canine prostate in relation to evolution to prostatic carcinoma, trying to identify the cellular origin and the alterations of pre-neoplastic lesions. Forty-four canine prostates were obtained at necropsy. Prostatic samples were fixed in methacarn, embedded in paraffin wax and sectioned into 5µm-thick slices for hematoxylin eosin (HE) staining and evaluated for the presence of hyperplasia, prostatitis, PIN and neoplasia. Moreover, HE stained sections representing each affection were used to determine the mean nuclear area by computerized morphometry. Tissue sections obtained in silanized slides were used in immunohistochemical staining for basal cells (p63 and 34E-12), connexins 32 and 43, androgen receptor (AR) and proliferating-cell nuclear antigen (PCNA). Quantitative real-time PCR to determine the expression level of AR at the mRNA level and Western blot to protein levels of connexin 43 were examined in samples collected using liquid nitrogen and kept at 80o C. The most common lesions were prostatitis and benign prostatic hyperplasia. The prostatic intraepithelial neoplasia exhibited a higher percent of basal cells and was highly proliferative, as demonstrated by PCNA immunohistochemistry. Moreover, these lesions exhibited heterogeneous nuclear AR staining, lower in comparision with benign acini. In contrast to human prostate, the canine prostate (normal or harboring PIN) did not express the connexins 32 and 43. The mean nuclear area measured by computerized morphometry was greater in epithelial cells of PIN and neoplastic acini than that of benign acini. We found variable RNAm AR expression in prostatic intraepithelial neoplasia and neoplasia by real-time PCR. These findings suggest that malignant basal cells may play a role in the origin of PIN and can proliferate despite the heterogeneous AR expression.

Full textProstate cancer (PCa) is the second most common cause of cancer in men. According to INCA, in Brazil, in 2016, approximately 61,200 new cases of prostate cancer are estimated. Objective: To identify the demographic and epidemiological characteristics, as well as data on the tumor staging of patients with PCa treated at the Oncology Unit of Hospital Marcio Cunha in the city of Ipatinga-MG in the years of 2012, 2013 and 2014. Methodology: This is a retrospective and descriptive study where 668 patients\' records, with a diagnosis of pathological diagnosis, were analyzed in the years 2012, 2013 and 2014, according to the list provided by the institution, with a diagnosis of PCa registered with ICD-10-C 61. The analyzed variables were: origin, year of diagnosis, age group, self-reported race, risk factors such as smoking, alcoholism, family history of PCa, total PSA at diagnosis, histological type of biopsy, Gleason score of biopsy, histological type of the surgical specimen, Gleason score of the surgical specimen. Data were analyzed using descriptive and inferential statistics, using SPSS software, version 19.0. Results: The highest incidence of PCa cases came from the most populated cities of the analyzed health micro-region and the most prevalent age group was between 61 and 80 years old, with prevalence in brown and whites and with a family history of 17.2% of first-degree relatives degree; With father in 37.3%, brother in 60.8% and son in 1.9%. Only 165 (25.9%) were smokers and 20.8% were alcoholics. PSA levels ranged from 4.1ng / e to 10ng / ml (49.5%) and the higher the age group the higher the PSA values. Brown patients had higher total PSA. When we evaluated whether there was a relationship between total PSA levels and risk factors such as smoking, alcohol consumption and family history, there was only a statistically significant relationship with alcohol consumption. There was concordance of the Gleason score between biopsy and surgical specimen in 70%, subgrade in 18.7% and overdose in 11.3%. Comparing the age of patients with Gleason score, the greater the patient\'s age, the greater the Gleason score of the material obtained by the transrectal biopsy. Smokers and alcoholists presented the highest Gleason score of the surgical specimen. Conclusion: The agreement between the Gleason score of the biopsy and the Gleason score of the surgical specimen was 70%; Higher PSA levels; The longer the age group, the more undifferentiated was the tumor (biopsy); Smokers and alcoholics presented more undifferentiated tumors in the surgical specimen; This is the first epidemiological study of PCa developed in the Vale do Aço region, the socio-demographic characterization and the associations found here can contribute with programs to develop actions of control of PCa in this region.

O câncer de próstata (CaP) é a segunda causa mais comum de câncer em homens. De acordo com o INCA, no Brasil, em 2016, estimam-se aproximadamente 61.200 novos casos de câncer de próstata. Objetivo: Identificar as características demográficas e epidemiológicas, bem como dados do estadiamento tumoral dos pacientes com CaP atendidos na Unidade de Oncologia do Hospital Marcio Cunha na cidade de Ipatinga-MG nos anos de 2012, 2013 e 2014. Metodologia: Trata-se de um estudo retrospectivo e descritivo onde foram analisados 668 prontuários de pacientes, com registro do diagnóstico anatomopatológico, atendidos nos anos de 2012, 2013 e 2014, conforme lista fornecida pela instituição, com diagnóstico de CaP cadastrados com CID-10 - C 61. As variáveis analisadas foram: procedência, ano do diagnóstico, faixa etária, raça autodeclarada, fatores de risco como tabagismo, etilismo, história familiar de CaP, PSA total ao diagnóstico, tipo histológico da biópsia, score de Gleason da biópsia, tipo histológico da peça cirúrgica, score de Gleason da peça cirúrgica. Os dados foram analisados empregando-se estatística descritiva e inferencial, utilizando o software SPSS, versão 19.0. Resultados: A maior incidência de casos de CaP foram provenientes das cidades mais populosas da microrregião de saúde analisada e faixa etária mais prevalente foi entre 61 e 80 anos com prevalência em pardos e brancos e com histórico familiar de 17,2% de parentes de primeiro grau; com o pai em 37,3%, o irmão em 60,8% e filho em 1,9%. Apenas 165 (25,9 %) eram fumantes e 20,8% etilistas. Os níveis de PSA ficaram entre 4,1ng/ e 10ng/ml (49,5%) e quanto maior a faixa etária maiores os valores do PSA. Pacientes pardos apresentaram PSA total mais elevado. Ao avaliarmos se existia relação entre os níveis de PSA total com fatores de risco como tabagismo, etilismo e histórico familiar, somente houve relação estatisticamente significativa com o etilismo. Houve concordância do score de Gleason entre biópsia e peça cirúrgica em 70%, subgraduação em 18,7% e supergraduação em 11,3%. Comparando a idade dos pacientes com Score de Gleason, quanto maior a idade do paciente maior foi o Score de Gleason do material obtido pela biópsia via transretal Pacientes tabagistas e etilistas apresentaram Score de Gleason da peça cirúrgica mais elevados. Conclusão: A concordância entre o Score de Gleason da biópsia e o Score de Gleason da peça cirúrgica foi de 70%; etilistas apresentaram PSA mais elevados; quanto maior foi a faixa etária, mais indiferenciado foi o tumor ( biópsia); pacientes tabagistas e etilistas apresentaram tumores mais indiferenciados na peça cirúrgica; este é o primeiro estudo epidemiológico de CaP desenvolvido na região do Vale do Aço, a caracterização sócio demográfica e as associações aqui encontradas podem contribuir com programas para desenvolver ações de controle do CaP nesta região.

Full textProstate cancer is the most incident malignant neoplasia among Brazilian men. Currently, great part of these tumors is confined to the prostate at the moment of the diagnosis. However, many tumors is clinically classified as local diseases, actually has already extra-prostatic extension, making the curative therapies ineffective. On the other hand, many patients with cancer without clinical significance are unnecessarily treated, because of the limited prognostic ability of the clinical stage. To determine the 5 and 10 years survival and to evaluate the clinical prognostic factors (pre-treatment) for patients with histologic diagnosis of adenocarcinoma of the prostate, in early clinical stages (I and II), in a hospital cohort of patients treated in the National Institute of Cancer, Rio de Janeiro, registered from 1990 to 1999. Kaplan-Meier survival functions were estimated, using the date of the histologic diagnosis as the initial time of follow-up and, as events, the deaths due to prostate cancer . To evaluate the prognostic factors, the hazard ratios (HR) were calculated, with confidence intervals of 95%, following the Coxs proportional hazards model. The following variables were analyzed as independent prognostic factors: age, color, degree of instruction, year of first treatment, histologic differentiation grade of the biopsy specimens (Gleason), clinical stage and pretreatment PSA. The assumption of proportionality of risks was assessed using Schoenfelds residuals analysis and, the influence of outliers in the model fitness, was addressed using martingale and score residuals. The studys cohort included 258 patients with the studys eligibility criteria, of which 46 had died during the follow-up time. The overall survival rate was of 88% for 5 years and 71% for 10 years. Age of 80 years or more, Gleason score higher than 6, PSA levels higher than 40ng/ml, B2 stage and white race were independent makers of bad prognosis. Classics prognostic factors were useful in the estimate of the prognostic in this cohort. The studys results showed that, for patients diagnosed in early stages, the socio-economic factors analyzed did not influence the prognostic. Other studies must be carried out, in the country, in order to investigate the differences in the prognostic in relation to the ethnicity.

Full textDespite new techniques and multiple therapeutic alternatives, locally advanced prostate cancer is a serious public health problem, resulting in significant morbidity and mortality rates, that remains a great challenge for urologists and oncologists. Several therapeutic strategies to treat localized prostate cancer have been successful such as conformational external beam radiation therapy, brachytherapy and cryoablation. In contrast, treatment of metastatic and locally advanced tumors may often involve androgenic suppression. However, there are no consensus on several aspects of hormonal therapy for locally advanced tumors such as the type of antiandrogenic drug to be used, early versus delayed hormonal therapy, association with other therapeutic modalities and the use of intermittent blockade. We set out to critically review important aspects and current indications of hormonal blockade in the locally advanced prostate tumors. There are no prospective and randomized study that compares current forms of surgical treatment versus radiation therapy of locally advanced prostate cancer. After radical prostatectomy, adjuvant hormonal therapy in the locally advanced disease reduces biochemical failure rates, although no benefit has been shown regarding metastatic free survival or overall suvival. Neoadjuvant androgen blockade enhances the proportion of patients with organ-confined disease and negative surgical margins but no benefit is seen regarding biochemical free recurrence. Neoadjuvant hormonal therapy to the radiotherapy improves local tumor control as well as it prolongs the diseasespecific survival, although there are no survival advantage. Adjuvant hormonal therapy offers overall survival advantage in patients with locally advanced prostate cancer treated with radiotherapy Long term adjuvant hormonal blockade offers survival benefit for patients with high Gleason score (8-10). LHRH analogues, bilateral orquiectomy and dietilestilbestrol were shown are equally effective as adjuvant therapy for patients with locally disease advanced. There are evidences that maximum androgenic blockade are not more efficient than monotherapy. Potential quality of life and costs advantages of intermittent ablation could be considered an alternative treatment for this group of patient
