Tendências e projeções da mortalidade pelos cânceres específicos ao gênero no Brasil / Trends and projections of mortality for specific cancers gender in Brazil

Os cânceres que acometem os órgãos genitais masculinos e femininos, em conjunto com o câncer de mama, são responsáveis por cerca de 20% dos óbitos por câncer no mundo. Conhecer os padrões de mortalidade por esses cânceres no Brasil, as mudanças que se produziram ao longo do tempo, os grupos mais vulneráveis e a carga de mortalidade que se apresentará no futuro são elementos básicos para a estruturação das ações assistenciais e de vigilância do câncer. O objetivo desse estudo foi analisar as tendências de mortalidade pelos cânceres que acometem órgãos que são específicos a cada gênero e projetar a mortalidade por esses cânceres até o ano de 2030, para o Brasil, regiões e estados da federação. Trata-se de um estudo ecológico de base populacional que analisou os óbitos, ocorridos no período 1996 a 2010, decorrentes dos cânceres de colo do útero, corpo do útero, mama feminina, ovários, vulva, vagina, próstata, pênis e testículos, registrados no Sistema de Informação sobre Mortalidade; as informações sobre população foram obtidas do Instituto Brasileiro de Geografia e Estatística. Foi aplicada a Regressão loglineal (Joinpoint regression) com taxas padronizadas (população mundial: ASR-W) para estimar o Annual Percentage Change (APC), o Average Annual Percentage Change (AAPC), o intervalo de confiança 95% e os pontos de inflexão da curva; as projeções foram calculadas através do programa Nordpred, inscrito no programa R, utilizando o modelo idade-período-coorte, analisando posteriormente se as mudanças que se produzirão no futuro serão decorrentes da exposição aos fatores de risco e/ou da estrutura da população exposta ao risco. Todas as análises também foram aplicadas para o conjunto de todos os óbitos por câncer (com exceção dos cânceres de pele não-melanoma).

Para o Brasil, a mortalidade pelos cânceres de pênis (APC=1,5% IC95% 0,7;2,3 p<0,05), testículos (APC=1,6% IC95% 0,5;2,8 p<0,05) e ovários (APC=0,8% IC95% 0,1; 1,5 p<0,05), mostraram tendência de aumento, enquanto os cânceres de vulva e vagina (APC=-0,1% IC95% -0,9; 0,7 p=0,8), corpo de útero (APC= -0,3 IC95% -1,0; 0,5 p=0,4), mama (APC=0,4% IC95% -0,2;1,0 p=0,2) e de próstata (AAPC= 1,1% IC95% -0,2; 2,4 p=0,1) apresentaram tendência de estabilidade. A mortalidade por câncer de colo de útero apresentou tendência de redução (APC=-1,7% IC95%-2,2; -1,1 p<0,05). A análise do agrupamento de todos os óbitos por câncer observou tendência de aumento na mortalidade para o sexo masculino até o ano de 2006 (APC= 1,2% IC95% 0,6;1,8 p<0,01), seguido de um período de estabilidade. Para o sexo feminino, a tendência é de estabilidade (APC=0,4% IC95% -0,2;-1,8 p=0,2). As taxas de mortalidade para todos os cânceres analisados mostraram, de maneira geral, tendência de redução nas regiões sul e sudeste, tendência de aumento nas regiões norte e nordeste, e estabilidade para a região centro oeste. Na projeção da mortalidade para o ano 2030, as regiões norte e nordeste responderão pelas maiores taxas de mortalidade para os cânceres analisados; todavia, para as demais regiões, será observada redução nas taxas em comparação com o último período observado. Destacase o câncer de testículo, para o qual será observado aumento de 33% na carga da mortalidade até o ano 2030. Para os demais cânceres, não serão observadas variações consideráveis nas taxas de mortalidade para o Brasil entre o último período observado e o último período projetado. A estrutura e o tamanho da população brasileira serão os fatores que explicarão os padrões de mortalidade por esses cânceres no futuro, embora para a região nordeste, as variações serão explicadas, em maior medida, pelo aumento do risco para esses cânceres.

Conclui-se, portanto, que existe uma marcante desigualdade na distribuição da mortalidade pelos cânceres específicos ao gênero no Brasil, onde as regiões mais pobres apresentam um quadro de aumento significativo do número de óbitos ao longo de uma série histórica, e que em 2030, essas regiões responderão pelas maiores taxas de mortalidade no país, com ênfase para os cânceres de pênis, testículos e ovários.

Cancers that attack male and female genital organs, along with breast cancer, are responsible for approximately 20% of cancer-related deaths in the world. Knowledge on the mortality patterns for these cancers in Brazil, the changes produced throughout time, the most vulnerable groups and the mortality burden in the future are basic elements for structuring assistance and vigilance actions for cancer. The objective of this study was to analyze the mortality trends of cancers that attack gender-specific organs, and project mortality until the year 2030, for Brazil, its geographic regions, and federation states. A population-based ecological study is presented herein, which analyzed deaths occurring within the period 1996-2010, due to cancers of the uterine cervix, uterine corpus, female breast, ovary, vulva, vagina, prostrate, penis and testicles, registered in the Mortality Information System. Data on population was obtained from the Brazilian Institute of Geography and Statistics. Joinpoint regression was applied with standardized rates (world population: ASR-W) to estimate the Annual Percentage Change (APC), the Average Annual Percentage Change (AAPC), the confidence interval 95% and the inflection points of the curve. The projections were calculated by the Norpred program, inscribed within the R program, utilizing the age-period-cohort model, with posterior analysis of whether the changes produced in the future will be consequences of exposition to risk factors and/or structure of the population exposed to risk. The analyses were also applied to the set of all cancer-related deaths (with exception for non-melanoma skin cancers). For Brazil, mortality due to cancers of penis (APC=1.5% CI95% 0.7;2.3 p<0.05), testicles (APC=1.6% CI95% 0.5;2.8 p<0.05) and ovary (APC=0.8% CI95% 0.1; 1.5 p<0.05) showed increasing trends, while cancers of vulva and vagina (APC=-0.1% IC95% -0.9; 0.7 p=0.8), uterine corpus (APC=-0.3 CI95% - 1.0; 0.5 p=0.4), breast (APC=0.4% CI95% -0.2;1.0 p=0.2) and prostrate (AAPC= 1.1% CI95% -0.2; 2.4 p=0.1) presented stable trends. Mortality due to cervical cancer presented reducing trends (APC=-1.7% ICI95%-2.2; -1.1 p<0.05). Analysis of the grouping of all cancer-related deaths presented increasing mortality trends for the male gender until the year 2006 (APC= 1.2% CI95% 0.6; 1.8 p<0.01), followed by a stability period. For females, the trend was stable (APC=0.4% CI95% -0.2;-1.8 p=0.2). The mortality rates for all analyzed cancers revealed, generally, reducing trends for the South and Southeast regions, increasing trends for the North and Northeast regions, and stability for the Midwest region. Mortality projections for the year 2030 indicate that the North and Northeast regions will suffer the highest mortality rates for the analyzed cancers; however, for the remaining regions, reduced rates will be observed in comparison with the last period analyzed. It must be highlighted that, for testicle cancer, there will be an increase of 33% in mortality burden until the year 2030. For the remaining cancers, significant variations will not be observed in mortality rates for the last observed period and the last projected period in Brazil. The structure and size of the Brazilian population are the factors explaining the mortality patterns for these cancers in the future, although for the Northeast region, the variations will be explained mostly by the increase in risk for these cancers. It is concluded that there is a pronounced inequality in the distribution of gender-specific cancer mortality in Brazil, where the poorer regions present a significant increasing situation of the number of deaths throughout a historical series. In 2030, these regions will present the highest mortality rates in the country, with emphasis on penis, testicle and ovarian cancers. (AU)

Testicular schistosomiasis as differential diagnosis for testicular nodules: a case report

Despite its infrequent occurrence, testicular schistosomiasis forming pseudo-tumors can be considered in the differential diagnosis of testicular tumors, especially in areas where the parasitic disease is endemic. In this report, we present a case of testicular schistosomiasis caused by Schistosoma mansoni and mimicking a testicular neoplasm. We describe the patterns of a testicular nodule on ultrasonography and magnetic resonance images in a 46-year-old man. The nodule was removed after a pre-operative diagnosis of a non-malignant lesion. Histology demonstrated granulomas with epithelioid macrophages and eosinophils around S. mansoni eggs within a fibrous tissue that formed a nodular structure.

Stage IIA and IIB testicular seminoma treated post-orchiectomy with radiation therapy versus other approaches: a population-based analysis of 241 patients

Objectives To evaluate post-orchiectomy utilization of radiation therapy (RT) versus other management approaches in stage IIA and IIB testicular seminoma patients. Materials and Methods Two hundred and forty-one patients with stage IIA and IIB testicular seminoma were identified between 1988 and 2003 using the Surveillance, Epidemiology, and End Results (SEER) database. Results Median follow-up was 10 years. Patients with stage IIA disease underwent RT more frequently than those with stage IIB disease (72% vs. 46%, respectively; P<0.001). There was no significant change in RT utilization for stage IIA or IIB disease between 1988 and 2003 (P = 0.89). Conclusions Between 1988 and 2003, stage IIA patients underwent RT more often than stage IIB patients in the United States. There was no significant change in RT utilization for stage IIA or IIB disease during this time period. Based on reports describing excellent progression-free survival with cisplatin-based chemotherapy, this approach has increased in popularity since 2003 and may eventually become the most popular treatment approach for both stage IIA and IIB testicular seminoma. .

Egresos hospitalarios por cáncer genitourinario en Chile: tercera parte / Hospital discharges because of genitourinary cancer: third part

El objetivo del presente trabajo fue actualizar el análisis de los egresos hospitalarios (EH) de cáncer genitourinario (CGU), específicamente cáncer de próstata, testículo, vejiga y riñón, en nuestro país. Para estos efectos se obtuvieron los datos del boletín de egresos hospitalarios del Ministerio de Salud (MINSAL) del año 2005, utilizándose los códigos de la clasificación internacional de enfermedades de la OMS (CIE-10). Los distintos diagnósticos fueron caracterizados según su composición geográfica y demográfica, comparándose con la información publicada en los reportes anteriores. La proporción de patología oncológica genitourinaria dentro de los egresos hospitalarios por patología genitourinaria ha experimentado un alza sostenida, correspondiendo 10,9 por ciento a cáncer de próstata, 4,28 por ciento a cáncer de testículo, 3,92 por ciento a cáncer de vejiga, y 2,2 por ciento a cáncer renal. El presente reporte constituye una aproximación a nuestro quehacer como urólogos en nuestro país, y al mismo tiempo grafica la necesidad de crear herramientas de registro epidemiológico más efectivas.

The aim of the study was to update the analysis of hospital discharges because of genitourinary cancer in our country. For these purposes, data were obtained from the registers of the Chilean Ministry of Health. Diseases were codified according to the WHO ICD-10 classification. Hospital discharges because of genitourinary cancer has shown a steady increase since 1993.According to the last register (2005), 10.9 percent corresponds to prostate cancer, 4.28 percent to testicular cancer,3.92 percent to bladder cancer and 2.2 percent to renal cell cancer. The present analysis is a rough estimation of our activity in urological oncology. However, more accurate epidemiological tools are needed.

Public awareness of testicular cancer and testicular self-examination in academic environments: a lost opportunity

BACKGROUND: Although testicular cancer is the most common cancer among 18- to 50-year-old males, healthcare providers seldom teach testicular self-examination techniques to clients, thus potentially missing opportunities for early detection. This form of cancer is easily diagnosable by testicular self-examination and is 96 percent curable if detected early. Periodic self-examination must be performed for early detection. Knowledge deficits and sociocultural norms contribute to low levels of health-related knowledge in most patients, resulting in undue delays before seeking medical advice. OBJECTIVE: Our aim is to assess the level of awareness of testicular cancer and the prevalence of the practice of testicular self-examination in academic environments to enable appropriate interventions. METHOD: A cross-sectional survey was administered to 750 consecutive males aged 18-50 years in three tertiary institutions in Port Harcourt from October 2008 to April 2009. RESULT: Knowledge or awareness of testicular cancer was poor. Almost all of the respondents were unaware that testicular lumps may be signs of cancer. A lump was typically construed as a benign carbuncle or something that could resolve spontaneously. The main factor contributing to respondents' lack of knowledge of testicular cancer was that few reported that they were "ever taught about testicular self-examination." CONCLUSION: Young adult men are unaware of their risk for testicular cancer, which is the most common neoplasm in this age group. Healthcare providers are not informing them of this risk, nor are they teaching them the simple early detection technique of self-examination of the testes.

Sperm banking for male cancer patients: social and semen profiles

PURPOSE: Report the characteristics of cryopreserved semen from a cohort of male cancer patients, attitudes towards cryopreservation and outcomes of semen samples based on a 12-year cryopreservation program. MATERIAL AND METHODS: Data from 98 male cancer patients whose sperm samples were banked were evaluated. Demographic parameters, semen characteristics, destination of sperm banked samples and questionnaires answered by the patients regarding cryopreservation time were evaluated. RESULTS: The cancer diagnoses were testicle (56.1 percent), prostate (15.3 percent), Hodgkin's lymphomas (9.2 percent), non-Hodgkin's lymphomas (7.1 percent), leukemia (3.1 percent) and other malignancies (9.2 percent). The patients with testicular cancer presented lower sperm concentration (p < 0.001); however, there were no differences with the percentage of normozoospermic patients among cancer type groups (p = 0.185). A shorter time between cancer diagnosis and sperm banking was observed for testicular and prostate cancer patients (p < 0.001). Most of the patients (89.5 percent) favored sperm banking as a fertility preservation method. CONCLUSIONS: Although less than 20 percent of banked sperm samples were disposed of, the majority of patients related sperm banking with safe for fertility preservation. Our results show that all male cancer patients of reproductive age facing cancer treatment could be offered sperm banking.

Idiopathic chronic hematocele of the vaginal sac

We report a 39-year-old male who presented non-traumatic testicular swelling and pain. Physical examination and sonography presented a suspicion of testicular tumor and both surgical exploration and inguinal orchiectomy were performed. Hematocele may both clinically and sonographically resemble a testicular tumor. The diagnostic study of choice is magnetic resonance, establishing the diagnosis and differentiating it from neoplasms.

Sarcoidose na infância com manifestacões raras: vasculite, acometimento do sistema nervoso central, ósseo e genital / Sarcoidosis in childhood with rare manifestations: vasculitis, central nervous system, bone and genital involvement

Sarcoidose é uma doenca granulomatosa sistêmica de ocorrência rara em criancas. Vasculite associada à sarcoidose é incomum e pode acometer vasos de pequeno a grande calibres. Envolvimento sintomático do sistema nervoso central e periférico ocorre em 5 por cento a 10 por cento dos pacientes e acometimento ósseo em 3 por cento a 13 por cento. Sarcoidose do trato geniturinário é extremamente rara. Descrevemos o caso de uma crianca de 12 anos com diagnóstico de sarcoidose associada à vasculite, acometimento do sistema nervoso central, ósseo e genital. O amplo espectro de manifestacões clínicas raras neste caso ilustra o caráter multissistêmico e multifacetário da sarcoidose.
