ABSTRACT

De acordo com a literatura, não há consenso sobre um tempo de atraso razoável desde o diagnóstico até a operação da prostatectomia radical (PR) sem piora do prognóstico. Objetivo: Avaliar a influência desse tempo no risco de recorrência da doença em pacientes com adenocarcinoma acinar da próstata tratados com PR. Método: Quatrocentos e doze pacientes submetidos à PR foram avaliados retrospectivamente. Destes, 172 foram excluídos por dados incompletos e outros 28, por estadiamento pré- -operatório como câncer de próstata de alto risco (PSA > 10 ng/mL ou escore de Gleason na biópsia > 7). Os estadiamentos pré e pós-operatórios foram comparados, e a análise de sobrevida feita pelo método de Kaplan-Meier para examinar a influência do tempo na discordância entre os estadiamentos pré e pós-operatórios. Resultados: Para os 212 pacientes da amostra, o tempo médio desde o diagnóstico até a PR foi de 176,1 ± 120,2 dias (mediana de 145,5 dias), variando de 29 a um máximo de 798 dias. A curva de Kaplan-Meier indicou que o câncer piorava quanto maior o atraso entre o diagnóstico e a operação. Pacientes submetidos à cirurgia dentro de 60 dias tiveram cerca de 95% de probabilidade de não aumentarem o risco inicial de recorrência. Esse número caiu para 80%, 70% e 50% nos pacientes operados em até 100, 120 e 180 dias, respectivamente. Conclusão: O atraso na realização da PR representa risco contínuo de recorrência da neoplasia. O tempo ideal para PR é de até 60 dias a partir da biópsia da próstata, uma vez que a probabilidade de upstaging é inferior a 5% nesse período.


There is no consensus in the literature on a reasonable delay time from diagnosis to radical prostatectomy (RP) surgery, without worsening the prognosis. Objective: To evaluate the influence of the delay on the risk of disease recurrence in patients with acinar adenocarcinoma of the prostate treated with RP. Method: Four hundred and twelve patients undergoing RP were retrospectively evaluated. Of these, 172 were excluded due to incomplete data and another 28 due to preoperative staging as high-risk prostate cancer (PSA > 10 ng/mL or Gleason score on biopsy > 7). Pre-and postoperative stagings were compared and survival analysis was performed using the Kaplan-Meier method to investigate the influence of time on discordance between pre- and postoperative stagings. Results:For the 212 patients of the sample, the average time from diagnosis to RP was 176.1 ± 120.2 days (median 145.5 days), ranging from 29 to a maximum of 798 days. The Kaplan-Meier curve indicated that the cancer worsened the longer the delay between diagnosis and surgery. Patients undergoing surgery within 60 days had an approximately 95% probability of not increasing the initial risk of recurrence. This number fell to 80%, 70% and 50% in patients operated on up to 100, 120 and 180 days, respectively. Conclusion:Delay in performing RP represents a continuous risk of relapse. The ideal time for RP is up to 60 days from prostate biopsy, as the probability of upstaging is less than 5% in this period


Según la literatura, no existe consenso sobre un tiempo razonable de retraso desde el diagnóstico hasta la cirugía de prostatectomía radical (PR), sin empeorar el pronóstico. Objetivo: Evaluar la influencia de este tiempo sobre el riesgo de recurrencia de la enfermedad en pacientes con adenocarcinoma acinar de próstata tratados con PR. Método: Se evaluaron retrospectivamente 412 pacientes sometidos a PR. De ellos, 172 fueron excluidos por datos incompletos y otros 28 por estadificación preoperatoria como cáncer de próstata de alto riesgo (PSA > 10 ng/mL o puntuación de Gleason en la biopsia > 7). Se compararon las estadificaciones pre y posoperatorias y se realizó un análisis de supervivencia utilizando el método de Kaplan-Meier para examinar la influencia del tiempo en la discordancia entre las estadificaciones pre y posoperatorias. Resultados: Para los 212 pacientes de la muestra, el tiempo promedio desde el diagnóstico hasta la PR fue de 176,1 ± 120,2 días (mediana 145,5 días), oscilando entre 29 y 798 días. La curva de Kaplan-Meier indicó que el cáncer empeoraba cuanto mayor era el retraso entre el diagnóstico y la cirugía. Los pacientes sometidos a cirugía dentro de los 60 días tenían aproximadamente un 95% de probabilidad de no aumentar el riesgo inicial de recurrencia. Esta cifra cayó al 80%, 70% y 50% en los pacientes operados hasta 100, 120 y 180 días, respectivamente. Conclusión: El retraso en la realización de la PR representa un riesgo continuo de restablecimiento de la neoplasia. El momento ideal para la PR es hasta los 60 días desde la biopsia de próstata, ya que la probabilidad de upstaging es inferior al 5% en este periodo.

Introduction: In Uruguay, prostate cancer ranks first in incidence and third in mortality among men. The majority of these cancers are diagnosed at early stages. Nowadays, active surveillance is an appropriate option for patients with adenocarcinoma of very low risk, low risk, or favorable intermediate risk. Objectives: To describe a population of patients with prostate cancer of very low risk, low risk, or favorable intermediate risk under active surveillance at COMERI. Materials and Methods: Descriptive, observational, retrospective study. Patients with prostate cancer of very low risk, low risk, or favorable intermediate risk treated between 2010 and 2018 at COMERI were included. Data were collected from the electronic clinical registry system. Results: Thirty-three patients were included, with a median age at diagnosis of 74 years. All patients underwent clinical monitoring and PSA determination every 3 months. Digital rectal examination was performed annually. The median time of active surveillance was 33 months. During follow-up, there were few variations in PSA values. 21% of patients underwent a repeat biopsy during active surveillance, and in all cases, the Gleason score remained unchanged. No patient discontinued active surveillance. Conclusion: In our setting, active surveillance is considered a valid therapeutic option for highly selected patients with prostate cancer of very low risk, low risk, or favorable intermediate risk, and it is well accepted by them.

ABSTRACT

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)

ABSTRACT

SUMMARY: In solid and malignant tumors, innate and adaptive immunity are combined in antitumor responses. This study aimed to analyze the activation of plasma cells and the correlation between the infiltration of B and T lymphocytes with the degree of malignancy or Gleason grade in human prostate biopsies diagnosed with cancer. Prostate cancer biopsies were obtained from the Clinical Hospital of Universidad de Chile (n=70), according to the bioethical norms of the institution. Histological sections of 5µm thickness were processed for immunohistochemistry with primary antibodies against BL and total TL (HRP/DAB). Recognition and quantification were performed under a Leica DM750 optical microscope. Microsoft Excel and GraphPad software were used for the statistical study. Correlation coefficient (Pearson) and mean comparison tests (Kruskal-Wallis and Dunn) and p≤ 0.05 were developed. B and T lymphocyte populations were inversely interregulated in prostate cancer (Gleason) (r= -0.46). Their relationship with Gleason grade is variable according to lymphocyte type (LB vs. Gleason r= -0.0.47 and LT vs. Gleason r= -0.21). Histological diagnosis of prostate cancer correlates with a predominance of LT. The malignancy of the pathology correlates with a predominance of LTs, according to the Gleason grade. The increased knowledge of B and T lymphocyte infiltration and plasma cell activation could be used to better target clinical trials on treatments based on immune system responses. Immunotherapy could be a new paradigm to apply better antitumor therapy strategies.


En tumores sólidos y malignos, la inmunidad innata y adaptativa se combinan en respuestas antitumorales. Este estudio tuvo como objetivo analizar la activación de células plasmáticas y la correlación entre la infiltración de linfocitos B y T con el grado de malignidad o grado de Gleason en biopsias de próstata humana diagnosticadas con cáncer. Las biopsias de cáncer de próstata se obtuvieron del Hospital Clínico de la Universidad de Chile (n=70), de acuerdo con las normas bioéticas de la institución. Secciones histológicas de 5 µm de espesor fueron procesadas para inmunohistoquímica con anticuerpos primarios contra LB y LT total (HRP/DAB). El reconocimiento y las cuantificaciones se realizaron bajo un microscopio óptico Leica DM750. Para el estudio estadístico se utilizaron los programas Microsoft Excel y GraphPad. Se desarrollaron pruebas de coeficiente de correlación (Pearson) y comparación de medias (Kruskal-Wallis y Dunn) y p≤ 0.05. Los resultados muestran que las poblaciones de linfocitos B y T están inversamente interreguladas en el cáncer de próstata (r= -0,4578). Su relación con el grado de Gleason es variable según el tipo de linfocito (LB vs Gleason r= -0,47* y LT vs Gleason r= -0,21). Se concluye que la malignidad del cáncer de próstata se correlaciona con un predominio de LT, versus el grado de Gleason. El mayor conocimiento de la infiltración de linfocitos B y T y la activación de células plasmáticas podría aprovecharse para una mejor orientación de ensayos clínicos en tratamientos basados en las respuestas del sistema inmunitario. La inmunoterapia podría ser un nuevo paradigma para aplicar mejores estrategias de terapias antitumorales.

ABSTRACT

Introdução: o câncer é um grave problema de saúde pública, considerado a segunda causa de óbitos no Brasil. Devido à sua relevância, é indispensável um controle eficiente dos casos através do acompanhamento da taxa de mortalidade. Dessa forma, o trabalho analisou a evolução da mortalidade por câncer para as localizações primárias mais frequentes, segundo sexo, durante o período de 2010 a 2020. Metodologia: trata-se de um estudo observacional descritivo, no qual os dados foram obtidos através do Atlas On-line de Mortalidade por Câncer. Os dados colhidos correspondem ao número de óbitos estratificados por tipo de câncer mais frequente, por ano estudado e por sexo, além das taxas de mortalidade específica bruta e a taxa de mortalidade ajustada por idade para o sexo masculino e feminino, para cada tipo de câncer em estudo, considerando a população padrão mundial, sendo avaliado por regressão linear a significância da tendência temporal. Resultados: no Brasil, no período de 2010 a 2020, as neoplasias mais frequentes em mulheres foram câncer de mama, câncer nos brônquios e pulmões, câncer no colo do útero, câncer no cólon e no pâncreas e em homens foram brônquios e pulmões, câncer de próstata, câncer de estômago, de esôfago e no fígado e vias biliares, sendo observado uma tendência crescente na taxa de mortalidade em mulheres e decrescente na taxa de mortalidade em homens. Conclusão: os resultados demonstram um possível comprometimento com a notificação durante o período de pandemia por Covid-19 e um possível rastreamento ainda deficiente de câncer na população masculina.


Introduction: cancer is a severe public health problem, considered the second cause of death in Brazil. Due to its relevance, efficient control of cases by monitoring the mortality rate is essential. Thus, the work analysed the evolution of cancer mortality for the most frequent primary locations, according to sex, from 2010 to 2020. Methodology: this is a descriptive observational study in which data were obtained through the Atlas Online Cancer Mortality Report. The data collected correspond to the number of deaths stratified by the most frequent type of cancer, by year studied and by sex, in addition to the crude specific mortality rates and the age-adjusted mortality rate for males and females, for each type of cancer. Understudy, considering the standard world population, the significance of the temporal trend is evaluated by linear regression. Results: in Brazil, from 2010 to 2020, the most frequent neoplasms in women were breast cancer, bronchial and lung cancer, cervical cancer, colon and pancreas cancer and in men, they were bronchial and lung cancer, cancer prostate, stomach, oesophagal and liver and biliary tract cancer, with an increasing trend in the mortality rate in women and a decreasing trend in the mortality rate in men. Conclusion: the results demonstrate a possible compromise with notification during the Covid-19 pandemic and a possible still poor screening of cancer in the male population.

ABSTRACT

Transgênero (trans) é um termo que alberga toda a diversidade de gênero. A incongruência de gênero faz parte desse espectro e refere-se à pessoa cuja identidade de gênero é oposta ao sexo que lhe foi atribuído no nascimento. A terapia hormonal de afirmação de gênero, bem como a cirurgia de afirmação de gênero, é necessária para adequar o corpo ao gênero ao qual a pessoa se identifica. Os homens trans necessitam da terapia com testosterona, que visa reduzir as concentrações de estradiol e incrementar a testosterona circulante para níveis fisiológicos masculinos, resultando em masculinização. A mulher trans receberá o estradiol, associado ou não a um antiandrogênico, visando reduzir a testosterona e incrementar o estrogênio para níveis femininos, resultando em feminização. A cirurgia de afirmação de gênero é, frequentemente, requerida para completar as modificações fenotípicas para o homem e a mulher trans. O ginecologista e obstetra tem um papel crucial no provimento de cuidados a essa população. O presente artigo visa sistematizar algumas ações que o ginecologista e obstetra pode oferecer e que têm potencial para melhorar a qualidade de vida dos homens e mulheres trans. (AU)


Transgenero (trans) is an umbrella term that encompasses all gender diversity. Gender Incongruity is part of this spectrum and refers to the person whose gender identity is opposed to the sex assigned to them at birth. Gender-affirming hormone therapy as well as gender-affirming surgery are necessary to adapt the body to the gender to which the person identifies. Trans men require testosterone therapy to reduce estradiol concentrations and increase circulating testosterone to male physiological levels resulting in masculinization. Trans women will receive estradiol associated or not with an antiandrogenic to reduce testosterone and increase estrogen to female levels resulting in feminization. gender-affirming surgery is often required to complete phenotypic modifications for trans men and women. The gynecologist and obstetrician plays a crucial role in to provide care to this population. This article aims to systematize some actions that the gynecologist and obstetrician can offer to improve the quality of life of trans men and women. (AU)

ABSTRACT

A prevalência das disfunções sexuais é alta na população geral. A capacidade de regular as experiências emocionais facilita o relacionamento mais adaptado aos estados internos e às condições ambientais. A prática da atenção plena promove atenção à experiência do momento presente ­ com curiosidade, abertura, aceitação, não reatividade e não julgamento ­ e tem se mostrado eficaz para melhorar muitas condições biopsicossociais, sendo utilizada em ambientes de saúde, escolas e locais de trabalho. O objetivo é apresentar atualizações na abordagem das dificuldades sexuais por meio do desenvolvimento da atenção plena. Entre outras recomendações, o treinamento para descentralizar a atenção, o desenvolvimento de habilidades para perceber pensamentos e sentimentos como estados mentais, não necessariamente reais, além de promover aceitação, compaixão e melhor gestão de pensamentos intrusivos e ruminativos são alguns pontos positivos da prática da atenção plena como única abordagem ou associada a outras. É apresentado um protocolo com grupo terapêutico para desenvolvimento da atenção plena para casais, em que o parceiro é sobrevivente do câncer de próstata. Segue uma proposta terapêutica com oito módulos desenvolvida em formato presencial e adaptada para a plataforma virtual. Os módulos são: definições e causas da disfunção sexual; conscientização crescente das sensações físicas; exploração do corpo e julgamentos sobre ele; consciência de pensamentos e crenças sexuais; trabalho com aversão e autotoque; consciência das sensações sexuais; foco sensorial com o parceiro; manutenção (e aumento) dos ganhos. Essa prática desenvolvida online abriu um campo importante para beneficiar portadores de disfunção sexual com dificuldade para buscar outras modalidades de intervenção.

ABSTRACT

Objective: To investigate the expression differences of LLGL2 between prostatic ductal adenocarcinoma (PDA) and prostatic acinar adenocarcinoma, and its potential clinical significance. Methods: Eighteen patients diagnosed of PDA or prostatic acinar adenocarcinoma with PDA component by histopathology during January 2015 and December 2019 in the Beijing Hospital, China were retrospectively studied. The transcriptome analysis was conducted using the tissue of PDA and prostatic acinar adenocarcinoma. Differentially expressed genes and the differences in expression profiles were identified. Further, differentially expressed proteins were verified by immunohistochemistry. Results: The tissue from 8 of the 18 patients were used for transcriptome analysis, the results of which were compared with data from public databases. 129 differentially expressed genes were identified. 45 of them were upregulated while 84 were downregulated. The results of gene enrichment analysis and gene oncology (GO) analysis revealed that the differentially expressed genes were mostly enriched in the hypertrophic cardiomyopathy and interleukin-17 related pathways. GPAT2, LLGL2, MAMDC4, PCSK9 and SMIM6 were differentially expressed between PDA and prostatic acinar adenocarcinoma. Moreover, LLGL2 was more likely expressed in the cytoplasm (P=0.04) than the nucleus (P<0.01) in PDA, compared with prostatic acinar adenocarcinoma. Conclusions: The gene expression profiling indicates that PDA are very similar to prostatic acinar adenocarcinoma. Among the differentially expressed proteins screened and verified in this study, the expression of GPAT2, LLGL2, MAMDC4 and PCSK9 is increased in PDA, while that of SMIM6 is reduced in PDA. The expression of LLGL2 shows significantly different patterns between PDA and prostatic acinar carcinoma, and thus may help differentiate PDA from prostatic acinar adenocarcinoma in clinical practice.

ABSTRACT

Prostate cancer (PCa) is a pernicious tumor with high heterogeneity, which creates a conundrum for making a precise diagnosis and choosing an optimal treatment approach. Multiparametric magnetic resonance imaging (mp-MRI) with anatomical and functional sequences has evolved as a routine and significant paradigm for the detection and characterization of PCa. Moreover, using radiomics to extract quantitative data has emerged as a promising field due to the rapid growth of artificial intelligence (AI) and image data processing. Radiomics acquires novel imaging biomarkers by extracting imaging signatures and establishes models for precise evaluation. Radiomics models provide a reliable and noninvasive alternative to aid in precision medicine, demonstrating advantages over traditional models based on clinicopathological parameters. The purpose of this review is to provide an overview of related studies of radiomics in PCa, specifically around the development and validation of radiomics models using MRI-derived image features. The current landscape of the literature, focusing mainly on PCa detection, aggressiveness, and prognosis evaluation, is reviewed and summarized. Rather than studies that exclusively focus on image biomarker identification and method optimization, models with high potential for universal clinical implementation are identified. Furthermore, we delve deeper into the critical concerns that can be addressed by different models and the obstacles that may arise in a clinical scenario. This review will encourage researchers to design models based on actual clinical needs, as well as assist urologists in gaining a better understanding of the promising results yielded by radiomics.

ABSTRACT

Introduction@#Prostate cancer is the third most common cancer among Filipino males. Ga-68 PSMA PET-CT and Lu-177 PRLT have been introduced in the Philippines for the diagnostics and therapy of prostate cancer. @*Objective@#The aim of this study is to compare treatment outcomes of standard therapy plus Lu-177 PSMA radioligand therapy and standard therapy alone among patients with prostatic cancer status-post castration using Ga-68 PET-CT as an outcome indicator. @*Methodology@#This is an ambispective cohort study on Ga-68 PSMA PET-CT scans performed between January 1, 2018 and July 31, 2021. Serum PSA data taken within one month of the PET-CT scans were also collected when available. The PET-CT images were reviewed by a radiologist for RECIST response, and by a nuclear medicine physician for PERCIST response . @*Results@#A total of 11 participants were included in the study. Six participants (55.5%) received standard therapy, while five participants (45.5%) received Lu-177 PSMA radioligand therapy plus standard therapy. There was no significant difference in the baseline and follow-up CT as shown by all p values > 0.05. A trend towards higher number of participants with non-complete/non-progressive RECIST response was noted in the control group than the treatment group, as well as higher number of participants with progressive or stable disease using the PERCIST response. @*Conclusion@#There were no significant differences noted in the clinical outcomes of participants who received Lu-177 PRLT and those with standard therapy alone. A trend towards decreasing serum PSA, CT and PET measurements were noted among patients given Lu-177 PRLT than those with standard therapy.

ABSTRACT

Introduction@#Limited access to the perineum and limited operating room space are just some of the limitations of the standard lithotomy docking for robot-assisted radical prostatectomy (RARP-LD). The side-docking technique (RARP-SD) may address these problems.@*Methods@#Thirty cases of robot-assisted radical prostatectomy were matched to 120 cases of RARP-LD cases by propensity scoring using age, body mass index (BMI), clinical T stage, biopsy Gleason score, and ultrasound prostate volume. Operative and docking time, complications were used to compare peri-operative and safety outcomes.@*Results@#Evaluation of 30 RARP-LD and 30 RARP-SD cases was done after propensity matching. Patient age, BMI, clinical T stage, biopsy Gleason score, and prostate volume were similar between the two groups (p>0.050). The mean docking time of RARP-SD is shorter than that of RARP-LD cases (7.56 vs. 4.12, p <0.001), but this did not translate to a shorter operative time. There were less peri-operative complications in the RARP-SD cases.@*Conclusions@#RARP-SD has a docking time and produces less complication than RARP-LD.

ABSTRACT

Using prostate-specific antigen (PSA) for prostate cancer (PCa) screening led to overinvestigation and overdiagnosis of indolent PCa. We aimed to investigate the value of prostate health index (PHI) and magnetic resonance imaging (MRI) prostate in an Asian PCa screening program. Men aged 50-75 years were prospectively recruited from a community-based PSA screening program. Men with PSA 4.0-10.0 ng ml -1 had PHI result analyzed. MRI prostate was offered to men with PSA 4.0-50.0 ng ml -1 . A systematic prostate biopsy was offered to men with PSA 4.0-9.9 ng ml -1 and PHI ≥35, or PSA 10.0-50.0 ng ml -1 . Additional targeted prostate biopsy was offered if they had PI-RADS score ≥3. Clinically significant PCa (csPCa) was defined as the International Society of Urological Pathology (ISUP) grade group (GG) ≥2 or ISUP GG 1 with involvement of ≥30% of total systematic cores. In total, 12.8% (196/1536) men had PSA ≥4.0 ng ml -1 . Among 194 men with PSA 4.0-50.0 ng ml -1 , 187 (96.4%) received MRI prostate. Among them, 28.3% (53/187) had PI-RADS ≥3 lesions. Moreover, 7.0% (107/1536) men were indicated for biopsy and 94.4% (101/107) men received biopsy. Among the men received biopsy, PCa, ISUP GG ≥2 PCa, and csPCa was diagnosed in 42 (41.6%), 24 (23.8%), and 34 (33.7%) men, respectively. Compared with PSA/PHI pathway in men with PSA 4.0-50.0 ng ml -1 , additional MRI increased diagnoses of PCa, ISUP GG ≥2 PCa, and csPCa by 21.2% (from 33 to 40), 22.2% (from 18 to 22), and 18.5% (from 27 to 32), respectively. The benefit of additional MRI was only observed in PSA 4.0-10.0 ng ml -1 , and the number of MRI needed to diagnose one additional ISUP GG ≥2 PCa was 20 in PHI ≥35 and 94 in PHI <35. Among them, 45.4% (89/196) men with PSA ≥4.0 ng ml -1 avoided unnecessary biopsy with the use of PHI and MRI. A screening algorithm with PSA, PHI, and MRI could effectively diagnose csPCa while reducing unnecessary biopsies. The benefit of MRI prostate was mainly observed in PSA 4.0-9.9 ng ml -1 and PHI ≥35 group. PHI was an important risk stratification step for PCa screening.

ABSTRACT

The final analysis of the phase 3 Targeted Investigational Treatment Analysis of Novel Anti-androgen (TITAN) trial showed improvement in overall survival (OS) and other efficacy endpoints with apalutamide plus androgen deprivation therapy (ADT) versus ADT alone in patients with metastatic castration-sensitive prostate cancer (mCSPC). As ethnicity and regional differences may affect treatment outcomes in advanced prostate cancer, a post hoc final analysis was conducted to assess the efficacy and safety of apalutamide in the Asian subpopulation. Event-driven endpoints were OS, and time from randomization to initiation of castration resistance, prostate-specific antigen (PSA) progression, and second progression-free survival (PFS2) on first subsequent therapy or death. Efficacy endpoints were assessed using the Kaplan-Meier method and Cox proportional-hazards models without formal statistical testing and adjustment for multiplicity. Participating Asian patients received once-daily apalutamide 240 mg ( n = 111) or placebo ( n = 110) plus ADT. After a median follow-up of 42.5 months and despite crossover of 47 placebo recipients to open-label apalutamide, apalutamide reduced the risk of death by 32% (hazard ratio [HR]: 0.68; 95% confidence interval [CI]: 0.42-1.13), risk of castration resistance by 69% (HR: 0.31; 95% CI: 0.21-0.46), PSA progression by 79% (HR: 0.21; 95% CI: 0.13-0.35) and PFS2 by 24% (HR: 0.76; 95% CI: 0.44-1.29) relative to placebo. The outcomes were comparable between subgroups with low- and high-volume disease at baseline. No new safety issues were identified. Apalutamide provides valuable clinical benefits to Asian patients with mCSPC, with an efficacy and safety profile consistent with that in the overall patient population.

ABSTRACT

Based on the androgen receptor(AR)/mammalian target of rapamycin(mTOR)signaling pathway, the effects of Xihuang Pills-medicated serum on the proliferation and apoptosis of prostate cancer LNCaP cells were investigated. The drug-containing serum of SD rats was prepared by intragastric administration of Xihuang Pills suspension. The effects of low-, medium-, and high-dose Xihuang Pills-containing serum on the in vitro proliferation of LNCaP cells were detected by cell counting kit-8(CCK-8). Flow cytometry was used to detect the apoptosis level of LNCaP cells after intervention with different concentrations of Xihuang Pills. Protein expression of cleaved cysteinyl aspartate-specific proteinase caspase-3(cleaved caspase-3), B-cell lymphoma-2(Bcl-2), and AR as well as the phosphorylation level of mTOR protein were detected by Western blot. The results showed that compared with the blank serum, the drug-medicated serum could blunt the activity of LNCaP cells. Low-, medium-, and high-dose Xihuang Pills-containing serum could significantly increase the cell apoptosis rate, increase the expression of cleaved caspase-3 protein, decrease the expression of Bcl-2 protein, reduce the expression of AR protein, and down-regulate the level of phosphorylated mTOR(p-mTOR). To study the effect of Xihuang Pills on the growth of LNCaP cells in vivo, different doses of Xihuang Pills were used to intervene in the subcutaneous graft model in nude mice inoculated with LNCaP cells. The expression levels of AR, mTOR, p-mTOR, Bcl-2, and cleaved caspase-3 were detected by Western blot. The results showed that the volumes of subcutaneous graft tumor in the low-dose, medium-dose, and high-dose Xihuang Pills groups significantly decreased compared with that in the model group. The weight of subcutaneous transplanted tumor in each group with drug intervention was significantly lower than that in the model group. Compared with the model group, the low-dose, medium-dose, and high-dose Xihuang Pills groups showed increased cleaved caspase-3 protein expression, decreased Bcl-2 and AR protein expression, and reduced p-mTOR protein expression. Further experiments showed that AR agonist R1881 could block the anti-proliferation and pro-apoptotic effects of Xihuang Pills. The mechanism of Xihuang Pills against prostate cancer is related to the inhibition of the AR/mTOR signaling pathway, inhibition of LNCaP cell proliferation, and induction of apoptosis in cancer cells.

ABSTRACT

Purpose: To conduct a systematic review of nanoparticles' use in the treatment of prostate cancer in animals. Methods: A systematic review was conducted in the databases PubMed, Scientific Electronic Library Online (SciELO), Latin American and Caribbean Health Sciences Literature (LILACS), Cochrane Library, and EMBASE, and the descriptors were chosen based on terms indexed in Health Sciences Descriptors (DeCS)/Medical Subject Headings (MESH), which are: nanoparticles, nanomedicine, and prostate cancer. The systematic review protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) with ID CRD42021271008. Results: A total of 3,897 articles was chosen; after reading the inclusion and exclusion criteria, six scientific articles with themes involving nanoparticles carrying medications were reached. Among the nanoparticles found, there were carboxymethylcellulose polymer, micellar casein nanoparticles, liquid crystal nanoparticles, serum albumin nanoparticles, and poly(ethylene glycol)-block-polylactide (mPEG-PLA) conjugated nanoparticles encapsulating cabazitaxel, docetaxel, and flutamide, which were nanoparticles used to treat prostate cancer in animals. Conclusions: Through using nanoparticles to encapsulate medications for treating prostate cancer in animals, studies show a decrease in weight and tumor reduction, with nanoparticles resulting in greater survival time than free medications. The improved permeability and retention effect of nanoparticles in the bloodstream contribute to their effectiveness.

ABSTRACT

ABSTRACT Objective: To analyze the direct costs of materials, medicines/solutions and healthcare professionals required to treat men with prostate cancer using High Intensity Focused Ultrasound. Method: Quantitative, exploratory-descriptive research, single case study type. Data were collected from electronic medical records/printed documentation from the Operating Room of a public teaching and research hospital. Health professionals estimated the respective time spent on activities in the following stages: "Before anesthetic induction", "Before performing thermal ablation", "During thermal ablation" and "After performing thermal ablation". Costs were calculated by multiplying the (estimated) time spent by the unit cost of direct labor, adding to the measured cost of materials, medicines/solutions. Results: The measured costs with materials corresponded to US$851.58 (SD = 2.17), with medicines/solutions to US$72.13 (SD = 25.84), and estimated personnel costs to US$196.03, totaling US$1119.74/procedure. Conclusion: The economic results obtained may support hospital managers in the decision-making process regarding the adoption of the High Intensity Focused Ultrasound for the treatment of prostate cancer.

ABSTRACT

Nas últimas décadas, tem se verificado o aumento de diagnósticos de câncer. No Brasil, a estimativa é de 16.830 novos casos de câncer de próstata para este ano. São escassas as pesquisas sobre os riscos de suicídio após o diagnóstico de um câncer em nosso país. O objetivo deste estudo foi avaliar longitudinalmente o risco para suicídio, qualidade de vida, ansiedade e depressão em uma amostra de pacientes com câncer de próstata localizado. Trezentos e trinta e três pacientes foram entrevistados ao diagnóstico e novamente a partir do 18º mês após ter recebido o diagnóstico. Foram aplicados os questionários: a seção de risco de suicídio do questionário Mini International Neuropsychiatric Interview (MINI), a Escala Hospitalar de Ansiedade e Depressão (HADS), o questionário Cut down, Annoyed by criticism, Guilty and Eye opener (CAGE) sobre abuso ou dependência de álcool, o Teste de Fagerström para Dependência a Nicotina (FTND), o instrumento de qualidade de vida para pacientes com câncer de próstata UCLA Prostate Cancer Index (UCLA-PCI), três perguntas sobre a percepção da primeira fase da pesquisa, um questionário sociodemográfico e incluídas quatro perguntas sobre a pandemia da Covid-19. A prevalência de risco de suicídio entre os pacientes com câncer de próstata ao diagnóstico foi de 5,7% e de 3,7% no 18º mês após o diagnóstico. Ao diagnóstico, o risco de suicídio associou-se ao escore positivo de ansiedade (p<0,001) e não ter depressão (p<0,001), ao estado civil casado (p=0,031), não morar sozinho (p=0,025), risco intermediário pela classificação de recidiva D'Amico (p=0,009), indicação para cirurgia (p=0,03), não ter tratamento psiquiátrico prévio (p<0,001) e história familiar de comportamento suicida (p=0,025). Após o 18º mês do diagnóstico, apenas a HADs positiva para ansiedade foi associada ao risco de suicídio (p<0,001). Na análise comparativa para os pacientes que responderam ao UCLA-PCI, observou-se associação significativa da qualidade de vida com o risco de suicídio em relação às funções físicas (p=0,037), vitalidade (p=0,006), saúde mental (p=0,014), função social (p=0,011), saúde geral (p=0,019) e transição para a saúde (p=0,013) aos pacientes recém diagnosticados e em relação às funções físicas (p=0,003), limitações de função da saúde física (p<0,001) e de saúde emocional (p<0,001), vitalidade (p=0,008), saúde mental (p=0,007), função social (p<0,0001), dor corporal (p=0,033), saúde geral (p=0,014) e transição para a saúde (p=0,016) após o 18º mês do diagnóstico. Fatores como qualidade de vida, ansiedade e depressão devem ser monitorados ao diagnóstico e ao longo do tratamento e a oferta de orientação e assistência emocional ser oferecida aos pacientes.


In recent decades, there has been an increase in cancer diagnoses. In Brazil, the estimate is 16,830 new cases of prostate cancer for this year. There is little research on the risks of suicide after the diagnosis of cancer in our country. The aim of this study was to longitudinally evaluate the risk for suicide, quality of life, anxiety and depression in a sample of patients with localized prostate cancer. Three hundred and thirty-three patients were interviewed at diagnosis and again from the 18th month after diagnosis. The following questionnaires were applied: the suicide risk section of the Mini International Neuropsychiatric Interview (MINI) questionnaire, the Hospital Anxiety and Depression Scale (HADS), the Cut down, Annoyed by criticism, Guilty and eye opener questionnaire (CAGE) on alcohol abuse or dependence, the Fagerström Test for Nicotine Dependence (FTND), the UCLA Prostate Cancer Index (UCLA-PCI) quality of life instrument for prostate cancer patients, three questions about the perception of the first phase of the survey, a sociodemographic questionnaire and included four questions about the Covid-19 pandemic. The prevalence of suicide risk among prostate cancer patients at diagnosis was 5.7% and 3.7% at 18 months after diagnosis. At diagnosis, the risk of suicide was associated with positive scores of anxiety (p<0.001) and not having depression (p<0.001), married marital status (p=0.031), not living alone (p=0.025), intermediate risk according to the D'Amico recurrence classification (p=0.009), indication for surgery (p=0.03), not having previous psychiatric treatment (p<0.001) and family history of completed suicide (p=0.025). After the 18th month of diagnosis, only anxiety positive HADs questionnaire was associated with suicide risk (p<0.001). In the comparative analysis for patients who answered to UCLA-PCI, a significant association was observed between quality of life and suicide risk in relation to physical functions (p=0.037), vitality (p=0.006), mental health (p=0.014), social function (p=0.011), general health (p=0.019) and transition to health (p=0.013) in newly diagnosed patients and in relation to physical functions (p=0.003), limitations of physical health function (p<0.001) and emotional health (p<0.001), vitality (p=0.008) mental health (p=0.007), social function (p<0.0001), body pain (p=0.033), general health (p=0.014) and transition to health (p=0.016) after the 18th month of diagnosis. Factors such as quality of life, anxiety and depression should be monitored at diagnosis and throughout treatment and the provision of guidance and emotional assistance should be offered to patients

ABSTRACT

El tumor fibroso solitario (TFS) es una neoplasia mesenquimatosa de tipo fibroblástico que, a pesar de ser localizado principalmente en pleura, se ha observado en otros órganos como la próstata. Por su parte, el tumor fibroso solitario de la próstata es una neoplasia de baja incidencia, crecimiento lento y potencial maligno incierto, que generalmente se compone de células fusiformes de apariencia citológicamente benignas, dispuestas en una arquitectura desorganizada, mezcladas con colágeno y pequeños vasos sanguíneos. Establecer su diagnóstico se ha vuelto más reproducible desde la identificación de la fusión de los genes NAB2-STAT6 por biología molecular, que lleva a la sobreexpresión de STAT6 por inmunohistoquímica, el cual es un marcador muy sensible y específico para TFS. Presentamos el caso clínico de un paciente que debutó con síntomas de compresión vesical, en quien se identificó una masa con epicentro en la próstata que infiltraba la vejiga y llegaba a la pared rectal, y que luego de estudios de patología, inmunohistoquímica y pruebas moleculares se clasificó como un TFS de la próstata, finalmente tratado con cistoprostatectomía radical más derivación urinaria


Solitary fibrous tumor (SFT) is a mesenchymal neoplasm of fibroblastic type, which despite being located mainly in the pleura, has been observed in other organs such as the prostate. On the other hand, solitary fibrous tumor of the prostate is a rare neoplasm, slow growing, and of uncertain malignant potential, which is generally composed of spindle cells of cytologically benign appearance, arranged in a disorganized architecture, mixed with collagen and small blood vessels. Establishing its diagnosis has become more reproducible since the identification of the NAB2-STAT6 gene fusion by molecular biology, leading to the overexpression of STAT6 by immunohistochemistry, a very sensitive and specific marker for SFT. We present a clinical report of a patient who consulted with symptoms of bladder compression, in whom a mass was identified with the epicenter in the prostate infiltrating into the bladder and reaching the rectal wall. Following histopathology study, immunohistochemistry and molecular tests it was classified as a SFT of the prostate, finally treated with radical cystoprostatectomy plus urinary shunt

En el 79.6% de las pacientes se contaba con la confirmación del diagnóstico mediante anatomía patológica. El tiempo entre el diagnóstico y el primer tratamiento oncológico fue ≤ 3 meses para el 88.2% de los pacientes. El total de los pacientes con EIV fueron contactados con la Unidad de Cuidados Paliativos. Únicamente el 15% de los casos fueron discutidos en Comité de Tumores. Conclusiones: Los datos analizados permitieron caracterizar el perfil epidemiológico del cáncer de los pacientes procedente de Soriano asistidos en el ámbito público y pueden contribuir a la implementación de políticas públicas orientadas a la prevención y por ende a la mejora en la asistencia pacientes asistidos.


Introduction: According to the Ministry of Health, cancer deaths constitute a quarter of the total deaths registered in Uruguay each year. Objective: To identify the epidemiological profile of patients diagnosed with cancer treated at the Departmental Hospital of Soriano. Materials and Methods: An observational, retrospective and descriptive study that included patients diagnosed with cancer attended at the Departmental Hospital of Soriano during 2022. The anonymity of the patients was maintained in the statistical analysis and approval was obtained from the Ethics Committee of the Hospital de Clínicas. Results: A total of 113 new patients were included; 53.1% were men, with a median age at diagnosis of 69 years old. The four most frequent tumors for both sexes were: breast, prostate, lung and colorectal; the distribution by stage was as follows: Stage IV 48.6% patients; Stage III 22.5%; Stage II 26.5%; and Stage I 2.6%. In 79.6% of the patients the diagnosis was confirmed by pathological anatomy. The time between diagnosis and first oncological treatment was ≤ 3 months for 88.2% of patients.
