Cost analysis of next-generation imaging in high-risk prostate cancer staging.

INTRODUCTION AND OBJECTIVE: Next-generation imaging (NGI) tests, such as choline PET/CT and PSMA PET, have shown to increase sensitivity in the detection of nodal and metastatic disease in prostate cancer. However, their use implies an increase in diagnostic costs compared to conventional imaging (CI) tests such as CT and bone scan. The aim of our study was to determine which diagnostic pathway is more cost-effective in high-risk prostate cancer. MATERIAL AND METHOD: Cost-effectiveness analysis of the available imaging tests (CI, Choline/PSMA PET) for the staging of high-risk prostate cancer. Sensitivity and specificity were estimated based on published evidence, and costs were collected from the Management Department. In order to carry out a cost-effectiveness analysis, five diagnostic pathways were proposed estimating the accurate diagnoses. RESULTS: PSMA PET was the most accurate diagnostic option. The CI diagnostic workup was the most economical and CI+PSMA the most expensive. Analyzing the diagnostic cost-effectiveness ratio, CI+PSMA proved to be the most expensive (€5627.30 per correct diagnosis) followed by PET PSMA (€4987.11), choline (€4599.84) and CI (€4444.22). CONCLUSIONS: PSMA PET is the most accurate strategy in staging distant disease in patients with high-risk prostate cancer. Radiotracer uptake tests such as CI have been shown to be the most cost-effective option, followed by choline and PSMA.

Cytoreductive surgery in patients with oligometastatic prostate cancer. Systematic review of the scientific literature.

INTRODUCTION: Interest in oligometastatic prostate cancer has spiked due to the emergence of new evidence regarding more specific and accurate imaging, and the wider use of minimally invasive techniques. Nevertheless, the optimal management of this pathology is yet to be determined. OBJECTIVE: Assess the efficacy and safety of cytoreductive surgery in patients suffering from oligometastatic prostate cancer. EVIDENCE GATHERING: Systematic review of the scientific literature (01/01/2010-31/12/2021) within the MedLine, Embase, Cochrane Library, Cinahl, Scopus, Spanish Healthcare Technology Assessment Agencies (AETS, Agencias de Evaluación de Tecnologías Sanitarias) and ClinicalTrials.gov databases. The keywords used were prostatectomy, prostatic neoplasm, radical prostatectomy; the free search terms were prostatectomy and oligometastatic prostate. The inclusion criteria comprised studies on patients with oligometastatic prostate cancer who had been operated on using radical cytoreductive prostatectomy. EVIDENCE SYNTHESIS: The systematic review included 4 observational studies, 2 clinical trials, and 2 case series, of moderate quality. The results observed suggest that oligometastatic prostate cancer patients who had undergone cytoreductive prostate surgery obtained a benefit in terms of efficacy. Conversely, the majority of these studies showed a reduction in the number of localized complications, when compared to the best systemic treatments. CONCLUSIONS: Cytoreductive surgery in this group of patients is a safe procedure that reduces the incidence of localized complications and that presents promising results with regard to survival rates. To date, the lack of prospective trials limits the use of this therapeutic option to experimental environments.

Health care costs of breast, prostate, colorectal and lung cancer care by clinical stage and cost component.

OBJECTIVE: To measure 3-year care costs of breast, prostate, colorectal and lung cancers disaggregated by site and clinical stage. METHOD: A retrospective observational design was employed to investigate care costs of cases recorded in the Registry of the Basque Country between 2010 and 2015. Data gathered included TNM stage and demographic, clinical and resource use variables. Total costs per patient with stage IV disease were calculated by combining generalized linear models with parametric survival analysis. Unit costs were obtained from the analytical accounting system of the Basque Health Service. RESULTS: The sample comprised 23,782 cancer cases (7801 colorectal, 5530 breast, 4802 prostate and 5649 lung cancer). The mean 3-year costs per patient with stage I to III disease were €11,323, €13,727, €8,651 and €12,023 for colorectal, breast, prostate and lung cancer, respectively. The most important cost components were surgery and chemotherapy. Total survival-adjusted costs until death for patients with stage IV disease (€27,568, €26,296, €16,151 and €15,931 for breast, colorectal, lung and prostate cancer, respectively) were higher than the 3-year costs for those with earlier-stage disease. CONCLUSIONS: This study quantitatively shows the pattern of changes in the economic burden of cancer throughout its natural history and the great magnitude of this burden for the health system. The use of indicators based on real-world data from each regional health service would allow cancer care in each region to be tailored to local population needs.

Changes in the ambulatory care of prostate cancer patients during the SARS-CoV-2 pandemic. Literature review and contribution of our group in telematic care.

INTRODUCTION AND OBJECTIVE: The COVID-19 pandemic has brought about changes in the management of urology patients, especially those with prostate cancer. The aim of this work is to show the changes in the ambulatory care practices by individualized telematic care for each patient profile. MATERIALS AND METHODS: Articles published from March 2020 to January 2021 were reviewed. We selected those that provided the highest levels of evidence regarding risk in different aspects: screening, diagnosis, treatment and follow-up of prostate cancer. RESULTS: We developed a classification system based on priorities, at different stages of the disease (screening, diagnosis, treatment and follow-up) to which the type of care given, in-person or telephone visits, was adapted. We established 4 options, as follows: in priority A or low, care will be given by telephone in all cases; in priority B or intermediate, if patients are considered subsidiary of an in-person visit after telephone consultation, they will be scheduled within 3 months; in priority C or high, patients will be seen in person within a margin from 1 to 3 months and in priority D or very high, patients must always be seen in person within a margin of up to 48 h and considered very preferential. CONCLUSIONS: Telematic care in prostate cancer offers an opportunity to develop new performance and follow-up protocols, which should be thoroughly analyzed in future studies, in order to create a safe environment and guarantee oncologic outcomes for patients.

Assessment of the role of Ga-68 PSMA I&T PET/CT in response evaluation to docetaxel therapy in castration resistant prostate cancer patients. / Evaluación del papel de la PET/TC con [68Ga]Ga-PSMA I&T en la evaluación de la respuesta a la terapia con docetaxel en pacientes con cáncer de próstata resistente a la castración.

OBJECTIVE: There have been only few studies investigating the role of PSMA ligands in the therapy response assessment of metastasized castration resistant prostate cancer (mCRPC) cases. In this study we aimed at evaluating the capability of 68Ga- prostate-specific membrane antigen (PSMA) I&T positron emission tomography/computerized tomography (PET/CT) in the assessment of therapeutic response in patients under docetaxel therapy for prostate cancer (PCa). MATERIAL AND METHODS: The clinical records of all mCRPC patients treated with docetaxel and referred to our department for 68Ga-PSMA I&T PET/CT imaging were retrospectively analysed. Sixteen patients (mean age 69 years, range 52-82 years) with castration-resistant prostate cancer patients receiving palliative docetaxel therapy and had undergone 68Ga-PSMA I&T PET/CT scan were included in the study. 68Ga-PSMA I&T PET/CT imaging was done and prostate specific antigen (PSA) levels were measured at baseline before administration of docetaxel (PET1) and after at least 3 cycles (range 4-12) of chemotherapy (PET2). Patient-based as well as lesion-based comparison of PET2 findings with PET1 findings were done. RESULTS: The change (decrease) observed in lymph node and prostate gland/prostatic bed SUVmax values after treatment compared to pretreatment was found to be statistically significant (P=.033). 3/16 patients (19%) were classified as progressive disease (PD), 4/16 (25%) as stable disease (SD), 9/16 (56%) as partial remission (PR) radiologically. An increasing PSA trend (IT) was observed in 4 patients (25%) and a decreasing PSA trend (DT) in 3 patients (18%). Nine patients showed a PSA response of ≥ 50% (56%). Of the 4 patients showing SD, 3 had IT, 3 had BR. Of the 9 patients who showed PR on PET studies, 8 patients showed BR and 1 patient showed DT. CONCLUSION: Imaging with 68Ga-PSMA PET/CT showed great concordance with biochemical response evaluation in terms of PSA levels, especially in patients showing good response to therapy. 68Ga-PSMA PET/CT was also successful in identifying progressive disease in patients showing paradoxical decline in PSA levels.

Impacto econômico da adoção de denosumabe em pacientes com metástases ósseas ou mieloma múltiplo sob a perspectiva do sistema de saúde privado brasileiro / Economic impact of denosumab adoption in cancer patients with bone metastases or multiple myeloma from the Brazilian private healthcare system's perspective

Objetivo: Estimar o custo por evento relacionado ao esqueleto (ERE) e o impacto econômico anual da adoção de denosumabe em pacientes com metástases ósseas secundárias ao câncer de mama, próstata e outros tumores sólidos ou mieloma múltiplo sob a perspectiva do sistema de saúde privado brasileiro. Métodos: Um modelo econômico foi desenvolvido para comparar os custos relacionados com denosumabe versus ácido zoledrônico na prevenção de EREs. O modelo incluiu os seguintes custos: medicamento, administração, monitoramento e manejo de ERE. O custo anual foi apresentado em reais (BRL) para 100 pacientes. Os custos do manejo de ERE [fratura vertebral (FV), fratura não vertebral (FNV), radiação óssea (RO), cirurgia óssea (CO) e compressão da medula espinhal (CME)] foram estimados a partir dos recursos e procedimentos coletados da revisão de literatura, bases de dados e painel Delphi. Dados coletados dos estudos clínicos randomizados relacionados com cada tipo de tumor na análise e de um estudo prospectivo observacional foram utilizados para estimar a eficácia clínica de denosumabe versus ácido zoledrônico. Resultados: O custo por cada tipo de ERE variou de BRL 27.246 a BRL 28.035 para FV, BRL 18.023 a BRL 18.811 para FNV, BRL 42.750 a BRL 43.538 para RO, BRL 18.023 a BRL 18.811 para CO e BRL 12.472 a BRL 13.260 para CME. A introdução de denosumabe foi estimada em economia anual por 100 pacientes de até BRL 1.072.043,14 para câncer de mama, BRL 1.212.822,79 para outros tumores sólidos, BRL 1.929.660,67 para câncer de próstata e BRL 77.965,07 para mieloma múltiplo. Conclusão: Esta análise sugere que EREs adicionam custos substanciais no manejo de pacientes com metástases ósseas. Dessa forma, o uso de denosumabe pode prevenir e retardar EREs em pacientes com câncer e pode possivelmente levar à redução do impacto econômico associado aos EREs sob a perspectiva dos pagadores de saúde privada brasileira.

Objective: To estimate the cost per SRE and annual economic impact of denosumab adoption in patients with bone metastases (BM) secondary to breast cancer, prostate cancer, other solid tumors or multiple myeloma from the Brazilian private healthcare system's perspective. Methods: An economic model was developed to compare the cost outcomes associated with denosumab instead of zoledronic acid for SRE prevention. The model included the following costs: drug, administration, monitoring and SRE management. Annual costs per 100 patients were reported in 2019 Brazilian currency (BRL). The SRE management costs (vertebral fracture (VF), non-vertebral fracture (NVF), radiation to bone (RB), surgery to bone (SB) and spinal cord compression (SCC)) were estimated from the resources and procedures collected from literature review, official database, and a Delphi panel. Data collected from randomized clinical trials related to each tumor type in the analysis and from a prospective observational study was used to estimate the clinical efficacy of denosumab vs zoledronic acid. Results: The cost per each type of SREs across all tumors ranged BRL 27,246 ­ BRL 28,035 for VF, BRL 18,023 ­ BRL 18,811 for NVF, BRL 42,750 ­ BRL 43,538 for RB, BRL 18,023 ­ BRL 18,811 for SB and BRL 12,472 ­ BRL 13,260 for SCC. The introduction of denosumab was estimated to result in annual savings per 100 patients of up to BRL 1,072,043.14 for breast cancer, BRL 1,212,822.79 for other solid tumors, BRL 1,929,660.67 for prostate cancer and BRL 77,965.07 for multiple myeloma. Conclusion: This analysis suggests that SREs add substantial costs to the management of patients with bone metastases. In this way, the use of denosumab would prevent and delay SREs in cancer patients and might possibly lead to reduce the economic burden associated with SREs, borne by Brazilian private healthcare payers.

Custo de tratamento do câncer de próstata resistente à castração por meio da aplicação da técnica Delphi no Sistema de Saúde Suplementar brasileiro / Cost of treating castration-resistant prostate cancer by applying the Delphi method to the Brazilian Private Healthcare System

Objetivo: Estimar os custos do tratamento de pacientes com câncer de próstata não metastático resistente à castração (nmCRPC) e metastático resistente à castração (mCRPC) no Sistema de Saúde Suplementar brasileiro. Métodos: Foi realizada uma busca na literatura para avaliar os dados já disponíveis do custo do tratamento do câncer de próstata no Brasil. Como os dados são escassos, optou-se por utilizar a técnica Delphi com seis médicos oncologistas para levantamento do uso dos recursos. O painel Delphi contou com três etapas, sendo duas on-line e uma presencial, abordando recursos, frequência e porcentagem de uso de exames de imagem e laboratoriais, e dados hospitalares (consultas, pronto-socorro, internações ­ clínica, cirúrgica e em unidade de terapia intensiva). Também foram solicitados dados de padrões de tratamento do câncer de próstata. Por fim, dados do manejo das metástases foram requeridos. Por meio das informações coletadas, foi desenvolvido o microcusteio do câncer de próstata resistente à castração na perspectiva do Sistema de Saúde Suplementar. Resultados: O custo total de tratamento da jornada do paciente com câncer de próstata resistente à castração foi igual a 480.497,25 BRL, e o tratamento unicamente da doença não metastática foi de 189.832,79 BRL e o da doença metastática, de 290.664,46 BRL. Conclusão: Os custos do tratamento de câncer de próstata metastático são substancialmente superiores aos custos do tratamento do paciente não metastático resistente à castração de alto risco, o que parece justificar economicamente o uso de medidas que previnam ou adiem o surgimento de metástases.

Objective: To estimate the treatment costs for patients with non-metastatic castration-resistant prostate cancer (nmCRPC) and metastatic castration-resistant prostate cancer (mCRPC) within the Brazilian private healthcare system. Methods: A literature search was performed to obtain currently available data on prostate cancer treatment costs in Brazil. As national data are scarce, a Delphi method with a specialist board was chosen with six oncologists for resource estimations. The Delphi panel had three steps: two online and one in-person, addressing what resources, frequencies, and percentages of use of imaging and laboratory exams, hospital data (including medical appointments, emergency room, hospitalizations - clinical, surgical and Intensive Care Unit). Data on prostate cancer treatment patterns were also requested. Finally, metastasis management data was required. Using the collected data, we developed a micro-costing model of castration-resistant prostate cancer in Brazil. Results: The total cost for the entire castration-resistant prostate cancer patient journey was 480.497,25 BRL, with the non-metastatic disease alone costing 189.832,79 BRL and the metastatic disease costing 290.664,46 BRL. Conclusion: The costs of treating metastatic prostate cancer are substantially higher than the treatment of high-risk castration-resistant non-metastatic patients, which seems to economically justify the use of measures that prevent or postpone metastasis.

Assessment of 68Ga-PSMA-11 PET positivity predictive factors in prostate cancer. / Valoración de factores predictivos de positividad en PET con 68Ga-PSMA-11 en el cáncer de próstata.

PURPOSE: Positron emission tomography (PET) studies with 68Ga-PSMA-11 (68Ga-HBED-CC-PSMA) have earned the attention of researchers, due to overexpression of PSMA in the tumoral tissues of prostate cancer. Our aim was to analyse the potential benefit of this radiotracer in the biochemical relapse of prostate cancer. MATERIAL AND METHODS: This retrospective analysis included 53 studies, performed on 50 male prostate cancer patients referred due to biochemical recurrence. In all cases, previous imaging techniques were negative or inconclusive. RESULTS: Of the 53 studies, 36 (68%) were positive. Significant differences were found between the positive and negative PET groups in Gleason's scale, PSA levels, PSAdt, late acquisition and the administration of androgen deprivation therapy during treatment (P<.05). Regarding PSA levels, 10 (48%) of the 21 patients with PSA<1ng/ml, obtained a pathological PET result. When the PSAdt was below six months, 86.7% of the patients obtained an abnormal PET. In the multivariate analysis, only Gleason's scale was associated independently with an abnormal PET result. CONCLUSIONS: 68Ga-PSMA-11 PET shows a high disease detection rate in patients where other techniques showed negative or doubtful images. Almost 50% of patients with prostate cancer biochemical recurrence and low PSA levels (<1ng/ml) have active disease on 68Ga-PSMA-11 PET, precisely where other radiotracers lack sensitivity.

Una sola tableta de Abiraterona con comida en vez de 4 tabletas en ayuno para pacientes con cáncer de próstata metastásico resistente a la castración: perspectivas fármaco-económicas en un país en desarrollo / One Pill of Abiraterone with Food Instead of Four Pills in Fasting State for Metastatic Castration Resistant Prostate Cancer Patients: Pharmaco-economic Perspectives in a Developing Country

Recientemente se publicó en el Journal of Clinical Oncology un estudio prospectivo aleatorizado fase II, que comparó dosis bajas de Abiraterona (250mg) administrada con comida vs la dosis estándar de dicho medicamento (1000mg), en pacientes con cáncer de próstata metastásico resistente a la castración (mCRPC)1 y concluyó que la dosis baja no es inferior a la dosis estándar en cuanto a la respuesta de PSA y a la supervivencia libre de progresión (PFS).

A prospective randomized phase II study comparing low dose Abiraterone (250 mg) administered with food versus the standard dose (1000 mg) in metastatic castration resistant prostate cancer, was recently published in The Journal of Clinical Oncology. It concluded that the low dose was non-inferior compared to the standard dose for the endpoints prostate specific antigen (PSA) response and progression free survival (PFS).

Avaliação da segurança e eficácia da abiraterona e enzalutamida pré e pós-quimioterapia no tratamento de pacientes com câncer de próstata metastático castração-resistente: revisão sistemática / Assessment of safety and treatment capacity and pre-treatment and post-treatment chemotherapy without treatment of patients with castration-resistant metastatic prostate cancer: systematic review

O câncer de próstata é no mundo e no Brasil. Alguns pacientes são diagnosticados em fase avançada um problema de saúde pública com alta prevalência ou progridem para tal após o tratamento inicial. Na fase do câncer de próstata metastático castração resistente (CPMCR), o emprego do acetato de abiraterona (AA) e enzalutamida (ENZ) surgem como alternativas de tratamento. O objetivo da tese foi sintetizar as evidências científicas disponíveis, através de uma revisão sistemática (RS), sobre a segurança e eficácia do AA e ENZ empregados em homens com CPMCR antes e após a quimioterapia. Procurou-se também avaliar os mesmos atributos das tecnologias em idosos com idade ≥ 75 anos e pacientes com metástase visceral. Foram pesquisadas cinco bases de dados bibliográficas eletrônicas ­ Medline, Embase, Lilacs, Scopus, Web of Science ­ e duas bases de registros de ensaios clínicos - CENTRAL e ClinicalTrials. Foram utilizados descritores do Medical Subject Headings (MeSH) e termos livres correspondentes ao problema de saúde e às tecnologias de interesse, combinados com uso dos operadores booleanos AND e OR, sem restrição inicial de idioma. Foram incluídos artigos no período de janeiro de 2006 a dezembro de 2018. Todas as etapas da RS foram realizadas por dois revisores independentes. A qualidade metodológica foi avaliada utilizando-se a ferramenta da Colaboração Cochrane. Foram identificadas 9.465 referências, sendo que apenas 29 artigos seguiram para fase de análise dos textos completos. Na segunda fase, apenas 12 estudos foram incluídos, com seis correspondentes a ensaios clínicos fase III originais, quatro contemplando o uso da AA (dois utilizando AA antes da QT e outros dois após-QT) e dois com utilização de ENZ (um antes da QT e um após a QT). Outros seis estudos trataram da análise de subgrupos, idade > 75 anos e com presença de metástase visceral. A sobrevida global e o tempo livre de progressão radiológica mostraram resultados favoráveis ao uso de AA e ENZ, inclusive em indivíduos na faixa etária com mais de 75 anos e com presença de metástase visceral com ganho de sobrevida de aproximadamente quatro meses. Os medicamentos evidenciaram baixas taxas de eventos adversos de graus moderados e graves, não havendo diferença estatística em relação ao uso do placebo em relação a eventos adversos grau V (entre 3,5 e 3,7%), e na taxa de descontinuidade do tratamento, ao redor de 6 a 8%. Ambos os medicamentos AA e ENZ evidenciaram benefícios similares. A despeito dos resultados favoráveis, estes apoiam-se em poucos ECCR fase III, o que deve ser levado em conta em decisões de eventual incorporação ao Sistema Único de Saúde

Prostate cancer is a public health problem with high prevalence worldwide and in Brazil. Some patients are diagnosed at an advanced stage or progress to it after initial treatment. In the phase of castration resistant metastatic prostate cancer (CPMCR), the use of abiraterone acetate (AA) and enzalutamide (ENZ) appear as treatment alternatives. The aim of the thesis was to synthesize the available scientific evidence through a systematic review (SR) on the safety and efficacy of AA and ENZ employed in men with CPMCR before and after chemotherapy (QT). We also sought to evaluate the same attributes of technologies in the elderly aged ≥ 75 years and patients with visceral metastasis. We searched five electronic bibliographic databases - Medline, Embase, Lilacs, Scopus, Web of Science - and two clinical trial record databases - CENTRAL and ClinicalTrials. Medical Subject Headings (MeSH) descriptors and free terms corresponding to the health problem and the technologies of interest were used, combined with the use of AND and OR boolean operators, without initial language restriction. Articles were included from January 2006 to December 2018. All stages of RS were performed by two independent reviewers. Methodological quality was assessed using the Cochrane Collaboration tool. 9,465 references were identified, and only 29 articles went to the full text analysis phase. In the second phase, only 12 studies were included, with six corresponding to original phase III clinical trials, four contemplating the use of AA (two using AA before QT and two after QT) and two using ENZ (one before QT and one after QT). Another six studies dealt with subgroup analysis, age> 75 years and visceral metastasis. Overall survival and time-free radiological progression showed favorable results for the use of AA and ENZ, even in individuals over 75 years of age and visceral metastasis with a survival gain of approximately four months. The drugs showed low rates of moderate and severe adverse events, with no statistical difference regarding placebo use compared to grade V adverse events (between 3.5 and 3.7%), and treatment discontinuation rate. , around 6 to 8%. Both AA and ENZ drugs showed similar benefits. Despite the favorable results, they are supported by few phase III ECCRs, which should be taken into account in decisions of eventual incorporation into the Unified Health System

Câncer de próstata com metástase óssea: impacto econômico para o Sistema de Saúde Suplementar brasileiro / Prostate cancer with bone metastasis: budget impact to the Brazilian Private Heathcare System

Objetivo: O objetivo deste trabalho foi avaliar o impacto de custo total do tratamento de câncer de próstata com metástase óssea na perspectiva do Sistema de Saúde Suplementar (SSS) brasileiro. Métodos: Trata-se de um estudo retrospectivo de coorte conduzido de um banco de dados administrativos fornecidos pela empresa Orizon. A população consistiu em pacientes com registro de câncer de próstata com metástases ósseas, ou procedimentos relacionados, que foram registrados em entradas hospitalares ou ambulatoriais e receberam pelo menos um tipo de tratamento. A perspectiva da análise foi o SSS e o horizonte temporal, uma mediana de 181 dias. O desfecho primário foi o custo global, no qual foram contemplados gastos com exames, procedimentos, materiais e medicamentos. A partir do desfecho primário, foram calculados o custo por paciente, o número de atendimentos por paciente e o custo por atendimento. Adicionalmente foram analisados os custos relacionados aos diferentes subgrupos de tratamentos destinados à doença. Resultados: O custo global relacionado aos atendimentos foi de R$ 21.391.034 (n = 181), o custo médio resultou em R$ 118.183 por paciente, com média de 10,48 atendimentos por paciente e R$ 11.282 por atendimento. Pela análise isolada dos cenários, os custos nos ambientes hospitalar (R$ 11.452.496) e ambulatorial (R$ 9.938.537) demonstraram que houve mais gastos relacionados aos procedimentos hospitalares. Conclusões: O estudo demonstrou elevado impacto econômico de tratamento de câncer de próstata com metástases ósseas no SSS, devido principalmente a maior necessidade de quantidade de hospitalizações com mais tempo de permanência.

Objective: The objective of this study was to evaluate the total cost impact of treatment of prostate cancer with bone metastasis under the Brazilian Private Healthcare System (SSS) perspective. Methods: This is a retrospective cohort study conducted from an administrative database provided by Orizon. The population consisted in patients with prostate cancer with bone metastasis registry, or related procedures, who were registered at hospital or ambulatory admission, and received at least one type of treatment. The perspective of the analysis was SSS and the time horizon was a median of 181 days. The primary outcome was global cost, considering expenses with exams, procedures, materials and drugs. From the primary outcome, cost per patient, number of visits per patient, and visit cost were calculated. Additionally, the costs related to the different subgroups of disease treatments were analyzed. Results: The global cost related to visits was R$ 21,391,034 (n = 181), the average cost resulted in R$ 118,183 per patient, with an average of 10.48 visits per patient and R$ 11,282 per visit. By the isolated analysis of the scenarios, the costs in the hospital (R$ 11,452,496) and ambulatory (R$ 9,938,537) environment demonstrated more expenses related to hospital procedures. Conclusions: The study demonstrated elevated budget impact of prostate cancer with bone metastasis treatment on the SSS, mainly due to greater need for the number of hospitalizations with a longer stay.

Asociación entre tamización de cáncer de próstata, vinculación al sistema de salud y factores asociados en adultos mayores: análisis secundario de la encuesta SABE Bogotá, Colombia / Relationship between prostate cancer screening, linkage to the health system and associated factors in older adults from Bogotá, Colombia: Secondary analysis of the SABE survey

Introducción y objetivos El cáncer de próstata es una enfermedad con alta prevalencia en nuestra población. Su diagnóstico temprano es importante para mejorar el pronóstico de esta enfermedad. El objetivo de este artículo es evidenciar los factores asociados a la oportunidad de tamización en adultos mayores de la ciudad de Bogotá, Colombia. Métodos Se analizaron los datos del estudio Salud, Bienestar y Envejecimiento (SABE) Bogotá 2012, que incluyó a 736 hombres de 60 años o más. Se utilizó como variable dependiente el autorreporte de examen de próstata en los 2 últimos años y se evaluó con respecto a factores sociodemográficos por medio de un análisis multivariado. Resultados Se encontró una prevalencia de cáncer de próstata del 3,15%. El 57,8% de los hombres se habían realizado al menos un examen de próstata. Aquellos afiliados al régimen contributivo tenían mayor oportunidad para ser tamizados con respecto a los vinculados/no asegurados (OR: 8,81) (IC95%: 2,92-26,63) (p < 0,001), al igual que los del régimen subsidiado (OR: 3,70) (IC95%; 1,20-11,41) (p = 0,023). Conclusión Existe una inequidad en cuanto a la oportunidad de tamización de cáncer de próstata según el tipo de seguridad social, por lo que se deben optimizar las estrategias de detección temprana que fortalezcan la inclusión de toda la población. Se necesitan más estudios que brinden mayor información sobre esta problemática.

Introduction Prostate cancer is a high prevalence disease in our male population. Early diagnosis is important in order to improve its prognosis. The aim of this article is to describe the factors associated with prostate cancer screening of older adults in Bogotá, Colombia. Materials and methods The study used data from the Bogotá 2012 Health, Well-Being, and Ageing (Salud, Bienestar y Envejecimiento [SABE]) survey, which included 736 men aged 60 years or older. The dependent variable used was self-reported prostate screening in the last 2 years. An analysis was performed to determine the between this variable and socio-demographic variables and comorbidities using multivariate analysis. Results There was a prevalence of prostate cancer of 3.15%, with 57.8% of the population having had at least one prostate examination. Those affiliated to a health insurance scheme were more likely to be screened than the uninsured with an OR: 8.81, 95% CI: 2.92-26.63, P < .001, as those affiliated to subsidized social security health scheme OR: 3.70, 95% CI: 1.20-11.41, P = .023, respectively). Conclusion There is inequity in the opportunity of screening for prostate cancer according to the type of health insurance scheme. Early detection strategies must be strengthened in order to include the entire population. Further studies are needed to provide more information on this issue.

Análise de custo-efetividade da técnica de IMRT para o tratamento do câncer de próstata localizado / Cost-effectiveness analysis of the IMRT technique for the treatment of localized prostate cancer

De acordo com os dados do Instituto Nacional de Câncer José Alencar Gomes da Silva (INCA), foram esperados, no Brasil, 61.200 novos casos de câncer de próstata para o ano de 2016. Estabelecido o diagnóstico, as opções terapêuticas são consideradas e se baseiam no estadiamento, dosagem do antígeno prostático específico (PSA) e escore histológico de Gleason. Segundo as diretrizes diagnósticas e terapêuticas do adenocarcinoma de próstata publicadas (2015), a técnica de radioterapia de intensidade modulada (IMRT) apresenta benefício no controle da doença e a menor probabilidade de toxicidade. Este trabalho teve como objetivo analisar a custo-efetividade da técnica de IMRT, na perspectiva do SUS, para o tratamento do câncer de próstata localizado, comparada com a técnica conformacional (3DRT). Foi construído um modelo de Markov e, uma coorte hipotética de homens de 65 a 70 anos foi acompanhada por 10 anos. A medida de desfecho clínico foram os anos de vida ajustados para qualidade (QALY). Os custos levantados se basearam nos valores da tabela APAC para um tratamento na dose de 74 a 76 Gy. Análise de sensibilidade probabilística baseada em simulação de Monte Carlo a fim de construir um limiar de aceitabilidade para incorporação da tecnologia em questão foi desenvolvida. O uso da tecnologia IMRT proporcionou um incremento de 0,79 QALY, mas não se mostrou custo-efetiva em relação aos pacientes que receberam radioterapia pela 3DRT. A IMRT apresentou uma razão de custoefetividade incremental de R$10.580,98/QALY. Ao considerar um limiar de aceitabilidade de três vezes o produto interno bruto (PIB) per capita, segundo recomendação da Organização Mundial de Saúde (2011), estimado em R$ 86.628,00/QALY, para 2016, o cenario para a incorporaçao dessa tecnologia se apresenta favoravel. A probabilidade do IMRT ser custo-efetiva foi de 72,5% para limiares de aceitabilidade de R$15.000,00

According to data from the Coordination of Prevention and Surveillance of the National Cancer Institute José Alencar Gomes da Silva (NCI) 61,200 new cases of prostate cancer were expected in Brazil in 2016. Once the diagnosis is established, the therapeutic options are considered according to risk groups described by D'Amico (1998), which are based on staging, prostate-specific antigen (PSA) and Gleason score. For localized prostate tumors, and for all risk groups, radiotherapy is indicated. According to the diagnostic and therapeutic guideline of prostate adenocarcinoma published in October 2015, the intensity modulated radiotherapy (IMRT) technique has a benefit in controlling the disease and the lower probability of toxicity. According to this premise, this study aimed to analyze the costeffectiveness of the IMRT technique, from the perspective of SUS, for the treatment of localized prostate cancer, compared with three-dimensional technique (3DRT). A mathematical model based on Markov models was constructed and a hypothetical cohort of men aged 65 to 70 years was followed up for 10 years. A probabilistic sensitivity analysis was performed based on Monte Carlo simulation to construct a threshold of acceptability for incorporation of the technology in question. As a result of the study, the use of IMRT technology provided a 0.79-year increase in quality-adjusted life years (QALY), but was not cost-effective compared to patients who received radiotherapy using the 3DRT. The IMRT presented an incremental cost-effectiveness ratio of R $ 10,580.98 / QALY. Based on a threshold of three times the per capita GDP, according to the WHO recommendation (2011), calculated at R $ 86,628.00 / QALY for 2016, the scenario for the incorporation of this technology is favorable. If a threshold of acceptability of R $ 28,876 is considered equivalent to a GDP per capita, the probability of IMRT being cost-effective is 72%

Prostate cancer mortality according to marginalization status in Mexican states from 1980 to 2013 / Comportamiento de la mortalidad por cáncer de próstata en México de acuerdo al índice de marginación estatal, de 1980 a 2013

Abstract Objective: To assess prostate cancer (PC) mortality in Mexico from 1980 to 2013, according to the state marginalization level. Materials and methods: Using age-adjusted rates in men ≥ 40 years old, we estimated trends and age-cohort-period effects of PC mortality from 1980-2013 according to state marginalization status by using a joinpoint regression model and a Poisson regression model proposed by Holford. Results: The PC mortality risk has increased nationwide at a constant rate (2% annually) during the past 13 years. The highest annual increase was observed among states with very high (4.4%) and high (7.7%) marginalization rates. In contrast, states with very low levels of marginalization showed a significant reduction of 1.5% per year. The main changes were observed in the 1945-1950 birth year cohorts. Conclusions: Differences in PC mortality across regions of Mexico may reflect differences in the timing of the diagnosis and treatment of PC.

Resumen Objetivo: Evaluar la mortalidad por cáncer de próstata (CP) en México de acuerdo con la marginación estatal de 1980 a 2013. Material y métodos: Mediante el método directo se estimaron las tasas de mortalidad por CP ajustadas por edad en hombres ≥ 40 años; se analizaron las tendencias y el efecto de edad-cohorte-periodo de la mortalidad por esta causa a nivel nacional y por nivel de marginación estatal, utilizando modelos joinpoint y de regresión de Poisson propuesto por Holford. Resultados: En los últimos 13 años, la mortalidad por CP a nivel nacional mostró un incremento constante (2% anual), principalmente en los estados de muy alta (4.4%) y alta marginación (7.7%), mientras que en los de muy baja hubo una reducción de 5% anual. Los principales cambios se observaron en las cohortes de nacimiento de 1945-1950. Conclusiones: Los resultados posiblemente reflejan las diferencias regionales, en la oportunidad del diagnóstico y tratamiento del CP.

Protocolo de evaluación rápida de tecnología sobre seguridad y efectividad del uso de Acetato de Abiraterona en el tratamiento de cáncer de próstata metastásico resistente a la castración sin quimioterapia previa / Protocol of rapid evaluation of technology on safety and effectiveness of the use of Abiraterone Acetate in the treatment of metastatic prostate cancer resistant to castration without prior chemotherapy

El cáncer constituye un problema de salud pública a nivel mundial, en la región de las Américas y en nuestro país, por su alta mortalidad como por la discapacidad que produce. El Estado Peruano ha declarado de interés nacional la atención integral del cáncer y el mejoramiento del acceso a los servicios oncológicos poniendo en marcha en Noviembre del año 2012 el Plan Nacional para la Atención Integral del Cáncer y Mejoramiento del Acceso a los Servicios Oncológicos del Perú denominado Plan Esperanza (D.S. N° 009-2012-SA). El Fondo Intangible Solidario de Salud solicita la evaluación de la tecnología sanitaria acetato de abiraterona como tratamiento en hombres adultos con cáncer de próstata metastásico resistente a la castración en los cuales la quimioterapia no está aún clínicamente indicada, la cual a su vez fue solicitada Hospital Nacional Hipólito Unánue, a raíz de un caso. Luego de una primera revisión, se determina que la tecnología acetato de abiraterona, comercializada en el Perú como Zytiga 250 mg, supera la tolerancia al riesgo para evaluación de tecnologías sanitarias en el Seguro Integral de Salud, por lo se consideró sea evaluada por el área de Evaluación de Tecnologías Sanitarias en el SIS Central.(AU)

Assessment and clinical factors associated with pain in patients undergoing transrectal prostate biopsy.

OBJECTIVES: To quantify the degree of pain experienced by patients who undergo ultrasound-guided transrectal prostate biopsy in standard clinical practice and assess the clinical factors associated with increased pain. MATERIAL AND METHODS: Analysis of a multicenter series of patients with prostate biopsy according to standard clinical practice. The biopsy was performed transrectally with a protocol of local anesthesia on the posterolateral nerve bundle. The pain was assessed at 20minutes into the procedure using the visual analog scale (0-10). The degree of pain was analyzed, and the association was studied using a univariate/multivariate analysis of selected clinical variables and the degree of pain. RESULTS: A total of 1188 patients with a median age of 64 years were analyzed. Thirty percent of the biopsies were diagnosed with a tumor. The median pain score was 2, with 65% of the patients reporting a pain score ≤2. The multivariate analysis showed that the prostate volume (RR, 1.34; 95% CI 1.01-1.77; P=.04), having a previous biopsy (RR, 2.25; 95% CI 1.44-3.52; P<.01), age (RR, .63; 95% CI .47-.85; P<.01) and feel palpation (RR, 1.95; 95% CI 1.28-2.96; P<.01) were factors independently associated with greater pain during the procedure. CONCLUSIONS: Transrectal biopsy with local anesthesia is a relatively painless technique. Factors such as age, a previous biopsy, pain on being touched and prostate volume were associated with the presence of greater pain during the procedure.

Avaliação do perfil nutricional de idosos com câncer de próstata nos municípios do Rio de Janeiro e Campo Grande / Assessment of nutritional status of elderly patients with prostate cancer in the municipalities of Rio de Janeiro and Campo Grande

A idade é considerada um importante fator de risco para o câncer. Com o crescimento do número de idosos na população, os casos de câncer em idosos serão cada vez mais frequentes.Devido a heterogeneidade que apresenta a população idosa, a Avaliação Geriátrica Multidimensional (AGM) tem sido utilizada para a determinação da saúde global de idoso com câncer e orientar a condução do tratamento. O domínio nutricional é um componente importante dessa avaliação, já que o risco nutricional está associado à ocorrência de efeitos adversos à saúde do idoso. O objetivo da dissertação foi caracterizar o perfil nutricional,estimar a prevalência de risco nutricional / desnutrição e avaliar fatores associados em pacientes idosos com câncer de próstata incidente no período que precede a definição da terapêutica oncológica, em Campo Grande, MS e no Rio de Janeiro, RJ. Este é um estudo seccional com 333 idosos. Foram analisadas variáveis sociodemográficas, clínicas e da AGM.O risco nutricional foi avaliado com a Mini Avaliação Nutricional reduzida (MANR). Foi também avaliado o Índice de Massa Corporal (IMC) segundo a classificação de Lipschitz. Utilizou-se o teste qui-quadrado para analisar diferenças entre as distribuições das categorias de classificação da MANR e do IMC segundo os itens componentes da MANR. A regressão de Poisson foi empregada na análise múltipla para avaliar a associação entre as diferentes covariáveis do estudo e a variável dependente. A idade média da população foi de 69,02 (mais ou menos 6,53) anos. Entre os idosos 73,0 por cento apresentavam estado nutricional adequado; 23,0 por cento a presentavam risco nutricional e 4,0 por cento eram desnutrição. As variáveis da MANR apresentaram proporções de idosos elevadas nos itens indicativos de risco / desnutrição com significância estatística...

Age is considered an important risk factor for cancer. With the growth of the number of eldersin the population, cancer cases will be more frequent. Due to the heterogeneity of the elderpopulation, the Multidimensional Geriatric Assessment (MGA) has been used to determinethe health condition of older adults with cancer and to aid in the conduction of treatment. Thenutritional domain is an important component of this evaluation, as it is associated withadverse health effects in elders. The objective of this study was to characterize the nutritionalprofile, to estimate the prevalence of nutritional risk/malnutrition and to evaluate associatedfactors, before therapeutic decision, in elders with incident prostate cancer, receivingoncological care in the National Health System in Campo Grande, MS and in Rio deJaneiro, RJ. This is a cross-sectional study with a sample of 333 elders. Socio-demographic, clinical and MGA variables were analyzed. Nutritional risk was evaluated by MNA-SF. TheIMC was evaluated according to the Lipschitz classification. Chi-square test was used to testthe statistical significance of differences among categories of the MNA-SF and the BMI classifications, according to the items that comprise the instrument. Poisson regression wasused for multivariate analysis in order to evaluate associations between the co-variables anddependent variable. Mean age was 69.02 (...) years. Among the older patients, 73.0 per cent hadadequate nutritional status; 23.0 per cent were at nutritional risk and 4.0 per cent had malnutrition. TheMNA-SF variables presented high proportions of elders in the items that indicate nutritionalrisk / malnutrition with statistical significance...
