Advanced renal cell carcinoma management: the Latin American Cooperative Oncology Group (LACOG) and the Latin American Renal Cancer Group (LARCG) consensus update.

PURPOSE: Renal cell carcinoma is an aggressive disease with a high mortality rate. Management has drastically changed with the new era of immunotherapy, and novel strategies are being developed; however, identifying systemic treatments is still challenging. This paper presents an update of the expert panel consensus from the Latin American Cooperative Oncology Group and the Latin American Renal Cancer Group on advanced renal cell carcinoma management in Brazil. METHODS: A panel of 34 oncologists and experts in renal cell carcinoma discussed and voted on the best options for managing advanced disease in Brazil, including systemic treatment of early and metastatic renal cell carcinoma as well as nonclear cell tumours. The results were compared with the literature and graded according to the level of evidence. RESULTS: Adjuvant treatments benefit patients with a high risk of recurrence after surgery, and the agents used are pembrolizumab and sunitinib, with a preference for pembrolizumab. Neoadjuvant treatment is exceptional, even in initially unresectable cases. First-line treatment is mainly based on tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs); the choice of treatment is based on the International Metastatic Database Consortium (IMCD) risk score. Patients at favourable risk receive ICIs in combination with TKIs. Patients classified as intermediate or poor risk receive ICIs, without preference for ICI + ICIs or ICI + TKIs. Data on nonclear cell renal cancer treatment are limited. Active surveillance has a place in treating favourable-risk patients. Either denosumab or zoledronic acid can be used for treating metastatic bone disease. CONCLUSION: Immunotherapy and targeted therapy are the standards of care for advanced disease. The utilization and sequencing of these therapeutic agents hinge upon individual risk scores and responses to previous treatments. This consensus reflects a commitment to informed decision-making, drawn from professional expertise and evidence in the medical literature.

Efficacy of immune checkpoint inhibitors combinations as first-line systemic treatment in patients with advanced urothelial carcinoma: A systematic review and network meta-analysis.

BACKGROUND: Combinations of immune checkpoint inhibitors (ICI) with platinum-based chemotherapy (PlatinumCT) or with another ICI in the first-line setting for patients with metastatic urothelial carcinoma (mUC) have mixed results. METHODS: Records were searched electronically from January 2019 to January 2024. A meta-analysis was performed to evaluate OS, progression-free survival (PFS), and overall response rate (ORR). RESULTS: Immune-based combinations were associated with an OS (HR: 0.75; 95% CI: 0.61-0.92; p < 0.001; I2= 84.1%) and PFS benefit in the intention-to-treat population (HR: 0.67; 95%CI: 0.51-0.89; p < 0.001; I2 = 89.7%). There was no ORR improvement with immune-based combinations (HR: 1.36; 95% CI:0.84-2.20; p < 0.001; I2 = 92.6%). CONCLUSION: This systematic review and study-level meta-analysis demonstrated that the immune-based combinations in first-line treatment for patients with mUC are associated with survival benefit.

"Non-metastatic, Castration-resistant Prostate Cancer: Diagnostic and Treatment Recommendations by an Expert Panel from Brazil".

INTRODUCTION: Non-metastatic, castration-resistant prostate cancer (nmCRPC) is an important clinical stage of prostate cancer, prior to morbidity and mortality from clinical metastases. In particular, the introduction of novel androgen-receptor signaling inhibitors (ARSi) has changed the therapeutic landscape in nmCRPC. Given recent developments in this field, we update our recommendations for the management of nmCRPC. METHODS: A panel of 51 invited medical oncologists and urologists convened in May of 2021 with the aim of discussing and providing recommendations regarding the most relevant issues concerning staging methods, antineoplastic therapy, osteoclast-targeted therapy, and patient follow-up in nmCRPC. Panel members considered the available evidence and their practical experience to address the 73 multiple-choice questions presented. RESULTS: Key recommendations and findings include the reliance on prostate-specific antigen doubling time for treatment decisions, the absence of a clear preference between conventional and novel (i.e., positron-emission tomography-based) imaging techniques, the increasing role of ARSis in various settings, the general view that ARSis have similar efficacy. Panelists highlighted the slight preference for darolutamide, when safety is of greater concern, and a continued need to develop high-level evidence to guide the intensity of follow-up in this subset of prostate cancer. DISCUSSION: Despite the limitations associated with a consensus panel, the topics addressed are relevant in current practice, and the recommendations can help practicing clinicians to provide state-of-the-art treatment to patients with nmCRPC in Brazil and other countries with similar healthcare settings.

A Systematic Review and Meta-Analysis of the Role of Immune Checkpoint Inhibitors (ICI) as Adjuvant Treatment for Localized High-Risk Muscle-Invasive Urothelial Carcinoma (MIUC).

Nivolumab, a PD-1 ICI has been recently approved for the adjuvant treatment of high-risk MIUC patients. However, conflicting data from another randomized controlled trial (RCT) with atezolizumab makes the benefit of this treatment uncertain. We performed a systematic review and study-level meta-analysis to evaluate the benefit in terms of disease-free survival (DFS) with ICI adjuvant treatment for patients with high-risk MIUC. Considering the Preferred Reporting Items for Systematic Review statement, a systematic search was performed in PUBMED/MEDLINE, Scopus and EMBASE up to October 30, 2021. The statistical analysis was performed by RevMan 5.4 software in intention-to-treat (ITT) population and in predetermined subgroups. Two RCTRCT, with a total of 1518 patients, met the inclusion criteria. Systemic immunotherapy was atezolizumab for 406 patients and nivolumab for 353 patients. In the ITT population there was a nonsignificant benefit with the systemic adjuvant immunotherapy (HR:0.79, 95% CI 0.62-1.00; z = 2.00) but with high heterogeneity (I2 = 65%). Regarding the subgroups, there was no benefit in PD-L1 negative (HR:0.81, 95% CI 0.70-1.00; z = 1.96, I2 = 0%) and in non-neoadjuvant chemotherapy (HR:0.95, 95% CI 0.78-1.15; z = 0.56, I2 = 0%). Adjuvant treatment with ICI to patients with high-risk MIUC reveals a nonsignificant impact in DFS. The lack of clinical benefit was demonstrated in all subgroups. These data reinforce the need for a careful selection of patients before offering this approach in daily practice.

Doxorubicin induces cardiotoxicity in a pluripotent stem cell model of aggressive B cell lymphoma cancer patients.

Cancer therapies with anthracyclines have been shown to induce cardiovascular complications. The aims of this study were to establish an in vitro induced pluripotent stem cell model (iPSC) of anthracycline-induced cardiotoxicity (ACT) from patients with an aggressive form of B-cell lymphoma and to examine whether doxorubicin (DOX)-treated ACT-iPSC cardiomyocytes (CM) can recapitulate the clinical features exhibited by patients, and thus help uncover a DOX-dependent pathomechanism. ACT-iPSC CM generated from individuals with CD20+ B-cell lymphoma who had received high doses of DOX and suffered cardiac dysfunction were studied and compared to control-iPSC CM from cancer survivors without cardiac symptoms. In cellular studies, ACT-iPSC CM were persistently more susceptible to DOX toxicity including augmented disorganized myofilament structure, changed mitochondrial shape, and increased apoptotic events. Consistently, ACT-iPSC CM and cardiac fibroblasts isolated from fibrotic human ACT myocardium exhibited higher DOX-dependent reactive oxygen species. In functional studies, Ca2+ transient amplitude of ACT-iPSC CM was reduced compared to control cells, and diastolic sarcoplasmic reticulum Ca2+ leak was DOX-dependently increased. This could be explained by overactive CaMKIIδ in ACT CM. Together with DOX-dependent augmented proarrhythmic cellular triggers and prolonged action potentials in ACT CM, this suggests a cellular link to arrhythmogenic events and contractile dysfunction especially found in ACT engineered human myocardium. CamKIIδ inhibition prevented proarrhythmic triggers in ACT. In contrast, control CM upregulated SERCA2a expression in a DOX-dependent manner, possibly to avoid heart failure conditions. In conclusion, we developed the first human patient-specific stem cell model of DOX-induced cardiac dysfunction from patients with B-cell lymphoma. Our results suggest that DOX-induced stress resulted in arrhythmogenic events associated with contractile dysfunction and finally in heart failure after persistent stress activation in ACT patients.

Brain metastases in gastroesophageal cancers-an underestimated complication.

BACKGROUND: Brain metastases represent a severe complication in many gastrointestinal malignancies especially those arising from the upper gastrointestinal tract, including cancer of the esophagus, gastroesophageal junction, and stomach (GEC). However, there is little knowledge about the onset or potential risk factors for brain metastases (BRMs) in upper gastrointestinal cancers resulting in a lack of screening guidelines for BRMs. METHODS: We analyzed 827 patients from our cancer registry suffering from gastroesophageal cancer (GEC) and treated at the University Medical Center Göttingen between January 2013 and December 2019 for the presence of BRMs. RESULTS: From 827 patients with GEC we found 54 patients with BRMs, resulting in an incidence of 6.5%. BRMs are more frequent in male patients (90.74% vs 9.26%, p = 0.0051) and in adenocarcinomas (90.74% vs 9.26%, p = 0.0117). Mean duration for the onset of BRMs from initial cancer diagnoses was 20.9 months in limited disease (curative approach) and 9.3 months in advanced disease (palliative approach) (p = 0.0026). However, early detection of BRMs is a prognostic factor since patients with successful resection of BRMs have a better prognosis compared to those with unresectable BRMs (5.93 vs 2.07 months, p = 0.0091). CONCLUSION: In this single-center retrospective study, brain metastases (BRMs) occur with a high frequency (6.5%) in gastroesophageal cancer (GEC), significantly more often in male patients and adenocarcinomas. Since survival of these patients considerably correlates with successful BRMs resection, our observations propose further prospective trails to validate our hypothesis and ultimately the implementation of routine screening procedures to detect asymptomatic brain metastases.

Establishing an ad hoc COVID-19 mortality surveillance during the first epidemic wave in Belgium, 1 March to 21 June 2020.

BackgroundCOVID-19-related mortality in Belgium has drawn attention for two reasons: its high level, and a good completeness in reporting of deaths. An ad hoc surveillance was established to register COVID-19 death numbers in hospitals, long-term care facilities (LTCF) and the community. Belgium adopted broad inclusion criteria for the COVID-19 death notifications, also including possible cases, resulting in a robust correlation between COVID-19 and all-cause mortality.AimTo document and assess the COVID-19 mortality surveillance in Belgium.MethodsWe described the content and data flows of the registration and we assessed the situation as of 21 June 2020, 103 days after the first death attributable to COVID-19 in Belgium. We calculated the participation rate, the notification delay, the percentage of error detected, and the results of additional investigations.ResultsThe participation rate was 100% for hospitals and 83% for nursing homes. Of all deaths, 85% were recorded within 2 calendar days: 11% within the same day, 41% after 1 day and 33% after 2 days, with a quicker notification in hospitals than in LTCF. Corrections of detected errors reduced the death toll by 5%.ConclusionBelgium implemented a rather complete surveillance of COVID-19 mortality, on account of a rapid investment of the hospitals and LTCF. LTCF could build on past experience of previous surveys and surveillance activities. The adoption of an extended definition of 'COVID-19-related deaths' in a context of limited testing capacity has provided timely information about the severity of the epidemic.

Single-center developing country analysis of radium-223 therapy in prostate cancer-preliminary results.

We reviewed the records of mCRPC patients treated with off-label use of Ra-223. Ra-223 efficiency in this non-study population was correlated to outcome measures overall survival (OS), progression-free survival (PFS), bone event-free survival, bone marrow failure (BMF), and disease-related biomarkers. There were no limits regarding the number of prior hormonal agents or chemotherapy received before or during Ra-223. Exclusion criteria consisted of baseline platelet counts below 50,000/mm3 and/or absolute neutrophil counts below 1,500/mm3. Twenty-eight patients received 130 cycles of Ra-223 between 2017 and 2018. The overall median OS was 15.6 months. However, in patients submitted to 4 or fewer cycles, the median OS was 9.1 months; in contrast, the median OS was 18.5 months in patients submitted to 5 or 6 cycles. There was a significant inverse correlation between the number of cycles and the occurrence of bone events (76.2% of the patients that completed 6 cycles did not present bone events, while 71.4% of the patients that had skeletal-related events were submitted to less than 6 cycles). 82.1% of the patients were submitted to concomitant therapies with no significant side effects. There was also a decrease in ALP and LDH levels throughout treatment. Radium-223 increased OS and decreased bone events, especially when patients were able to complete 5-6 cycles. The proper selection of patients is crucial to improve outcomes.

Post-migration acquisition of HIV: Estimates from four European countries, 2007 to 2016.

BackgroundThe assumption that migrants acquire human immunodeficiency virus (HIV) before migration, particularly those from high prevalence areas, is common.AimWe assessed the place of HIV acquisition of migrants diagnosed in four European countries using surveillance data.MethodsUsing CD4+ T-cell count trajectories modelled to account for seroconversion bias, we estimated infection year of newly HIV-diagnosed migrants residing in the United Kingdom (UK), Belgium, Sweden and Italy with a known arrival year and CD4+ T-cell count at diagnosis. Multivariate analyses identified predictors for post-migration acquisition.ResultsBetween 2007 and 2016, migrants constituted 56% of people newly diagnosed with HIV in the UK, 62% in Belgium, 72% in Sweden and 29% in Italy. Of 23,595 migrants included, 60% were born in Africa and 70% acquired HIV heterosexually. An estimated 9,400 migrants (40%; interquartile range (IQR): 34-59) probably acquired HIV post-migration. This proportion was similar by risk group, sex and region of birth. Time since migration was a strong predictor of post-migration HIV acquisition: 91% (IQR: 87-95) among those arriving 10 or more years prior to diagnosis; 30% (IQR: 21-37) among those 1-5 years prior. Younger age at arrival was a predictor: 15-18 years (81%; IQR: 74-86), 19-25 years (53%; IQR: 45-63), 26-35 years (37%; IQR: 30-46) and 36 years and older (25%; IQR: 21-33).ConclusionsMigrants, regardless of origin, sex and exposure to HIV are at risk of acquiring HIV post-migration to Europe. Alongside accessible HIV testing, prevention activities must target migrant communities.

Consensus on the Treatment and Follow-Up for Metastatic Castration-Resistant Prostate Cancer: A Report From the First Global Prostate Cancer Consensus Conference for Developing Countries (PCCCDC).

PURPOSE: To present a summary of the recommendations for the treatment and follow-up for metastatic castration-resistant prostate cancer (mCRPC) as acquired through a questionnaire administered to 99 physicians working in the field of prostate cancer in developing countries who attended the Prostate Cancer Consensus Conference for Developing Countries. METHODS: A total of 106 questions out of more than 300 questions addressed the use of imaging in staging mCRPC, treatment recommendations across availability and response to prior drug treatments, appropriate drug treatments, and follow-up, and those same scenarios when limited resources needed to be considered. Responses were compiled and the percentages were presented by clinicians to support each response. Most questions had five to seven relevant options for response including abstain and/or unqualified to answer, or in the case of yes or no questions, the option to abstain was offered. RESULTS: Most of the recommendations from this panel were in line with prior consensus, including the preference of a new antiandrogen for first-line therapy of mCRPC. Important aspects highlighted in the scenario of limited resources included the option of docetaxel as treatment preference as first-line treatment in several scenarios, docetaxel retreatment, consideration for reduced doses of abiraterone, and alternative schedules of an osteoclast-targeted therapy. CONCLUSION: There was wide-ranging consensus in the treatment for men with mCRPC in both optimal and limited resource settings.

Consensus on the Treatment and Follow-Up for the Nonmetastatic Castration-Resistant Prostate Cancer: A Report From the First Prostate Cancer Consensus Conference for Developing Countries.

PURPOSE: To present a summary of the recommendations for the treatment and follow-up for the biochemical recurrence of castration-resistant prostate cancer (PCa) as acquired through a questionnaire administered at the Prostate Cancer Consensus Conference for Developing Countries. METHODS: A total of 27 questions were identified as relating to this topic. Responses from the clinician were tallied and are presented in percentage format. Topics included the use of imaging in staging, treatment recommendations across different patient scenarios of life expectancy and prostate-specific antigen (PSA) doubling time, and follow-up for nonmetastatic castration-resistant PCa. RESULTS: A consensus agreed that in optimal conditions, positron emission tomography-computed tomography with prostate-specific membrane antigen would be used although in limited resource situations the combined use of CT of the abdomen and pelvic (or pelvic MRI), a bone scan, and a CT of the thorax or chest x-ray was recommended. In cases when PSA levels double in < 10 months, more than 90% of clinicians agreed on the use of apalutamide or enzalutamide, regardless of life expectancy. With a doubling time of more than 10 months, > 54% of experts recommended no treatment independent of life expectancy. More than half of the experts, regardless of resources, recommended follow-up with a physical examination and PSA levels every 3-6 months and imaging only in the case of symptoms. CONCLUSION: The voting results and recommendations presented in this document can be used by physicians to support management for biochemical recurrence of castration-resistant PCa in areas of limited resources. Individual clinical decision making should be supported by available data.

Advanced renal cell carcinoma (RCC) management: an expert panel recommendation from the Latin American Cooperative Oncology Group (LACOG) and the Latin American Renal Cancer Group (LARCG).

PURPOSE: The outcome of RCC has improved considerably in the last few years, and the treatment options have increased. LACOG-GU and LARCG held a consensus meeting to develop guidelines to support the clinical decisions of physicians and other health professionals involved in the care of RCC patients. METHODS: Eighty questions addressing relevant advanced RCC treatments were previously formulated by a panel of experts. The voting panel comprised 26 specialists from the LACOG-GU/LARCG. Consensus was determined as 75% agreement. For questions with less than 75% agreement, a new discussion was held, and consensus was determined by the majority of votes after the second voting session. RESULTS: The recommendations were based on the highest level of scientific evidence or by the opinion of the RCC experts when no relevant research data were available. CONCLUSION: This manuscript provides guidance for advanced RCC treatment according to the LACOG-GU/LARCG expert recommendations.

First-line Treatment of Metastatic Renal Cell Carcinoma in the Immuno-oncology Era: Systematic Review and Network Meta-analysis.

Combination treatments with immuno-oncology (IO) agents and IO agents plus a vascular endothelial growth factor receptor tyrosine kinase inhibitor (VEGFR-TKI) have been approved for first-line treatment of patients with metastatic renal cell carcinoma (mRCC). No direct comparisons have been performed among these treatment options. We performed a systematic review and network meta-analysis to compare and rank the available regimens for first-line treatment in terms of survival benefit and efficacy. In accordance with the Preferred Reporting Items for Systematic Review statement, a systematic search of reported studies was performed in MEDLINE, the Cochrane Central Register of Controlled Trials, and EMBASE up to May 31, 2019. Network meta-analysis models were adjusted using the Bayesian method. Four randomized clinical trials, with a total of 3758 patients, met the inclusion criteria. Considering systemic therapy, 1880 patients had received sunitinib and 550, 432, 442, and 454 patients had received ipilimumab plus nivolumab (ipi + nivo), pembrolizumab plus axitinib (pembro + axi), avelumab plus axitinib (avelu + axi), and atezolizumab plus bevacizumab (atezo + bev). No difference was found in overall survival between ipi + nivo and pembro + axi for the intention to treat population (hazard ratio [HR], 1.34; 95% credible interval [CrI], 0.92-1.97). No difference was found in progression-free survival among the treatments. The overall response rate (ORR) was superior with pembro + axi and avelu + axi compared with the ORR with the other treatments (atezo + bev vs. pembro + axi: HR, 0.66; 95% CrI, 0.52-0.84; ipi + nivo vs. pembro + axi: HR, 0.73; 95% CrI, 0.59-0.90; atezo + bev vs. avelu + axi: HR, 0.55; 95% CrI, 0.43-0.71; avelu + axi vs. ipi + nivo: HR, 1.66; 95% CrI, 1.31-2.12), with no differences across them (HR, 1.21; 95% CrI, 0.95-1.53). In the present indirect comparison, for an intention to treat population, we found no survival differences between pembro + axi and ipi + nivo. All treatments showed better progression-free survival compared with sunitinib that was similar among them. The combination of an IO agent (pembrolizumab or avelumab) and axitinib seemed to be the most effective therapy for the ORR.

Exploring HIV-1 Transmission Dynamics by Combining Phylogenetic Analysis and Infection Timing.

HIV-1 pol sequences obtained through baseline drug resistance testing of patients newly diagnosed between 2013 and 2017 were analyzed for genetic similarity. For 927 patients the information on genetic similarity was combined with demographic data and with information on the recency of infection. Overall, 48.3% of the patients were genetically linked with 11.4% belonging to a pair and 36.9% involved in a cluster of ≥3 members. The percentage of early diagnosed (≤4 months after infection) was 28.6%. Patients of Belgian origin were more frequently involved in transmission clusters (49.7% compared to 15.3%) and diagnosed earlier (37.4% compared to 12.2%) than patients of Sub-Saharan African origin. Of the infections reported to be locally acquired, 69.5% were linked (14.1% paired and 55.4% in a cluster). Equal parts of early and late diagnosed individuals (59.9% and 52.4%, respectively) were involved in clusters. The identification of a genetically linked individual for the majority of locally infected patients suggests a high rate of diagnosis in this population. Diagnosis however is often delayed for >4 months after infection increasing the opportunities for onward transmission. Prevention of local infection should focus on earlier diagnosis and protection of the still uninfected members of sexual networks with human immunodeficiency virus (HIV)-infected members.

Renal cell cancer treatment: an expert panel recommendation from the Latin American cooperative group-genitourinary and the Latin American renal cancer group: focus on surgery.

BACKGROUND: Renal cell cancer (RCC) is one of the 10 most common cancers in the world, and its incidence is increasing, whereas mortality is declining only in developed countries. Therefore, two collaborative groups, The Latin American Oncology Cooperative Group-Genitourinary Section (LACOG-GU) and the Latin American Renal Cancer Group (LARCG), held a consensus meeting to develop this guideline. METHODS: Issues (134) related to the treatment of RCC were previously formulated by a panel of experts. The voting panel comprised 26 specialists (urologists and medical oncologists) from the LACOG-GU/LARCG. A consensus was reached if 75% agreement was achieved. If there was less concordance, a new discussion was undertaken, and a consensus was determined by the most votes after a second voting session. RESULTS: The expert meeting provided recommendations that were in line with the global literature; 75.0% of the recommendations made by the panel of experts were evidence-based level A, 22.5% of the recommendations were level B, and 2.5% of the recommendations were level D. CONCLUSIONS: This review suggests recommendations for the surgical treatment of RCC according to the LACOG-GU/LARCG experts.

Estimates of the HIV undiagnosed population in Belgium reveals higher prevalence for MSM with foreign nationality and for geographic areas hosting big cities.

INTRODUCTION: Increasing our knowledge on geographic areas and key populations most affected by HIV is essential to improve prevention and care and to ensure a more focused HIV response. Here, we estimated the prevalence of undiagnosed HIV infections in Belgium and its distribution across geographic areas and exposure groups. METHODS: We used surveillance data on newly diagnosed HIV cases and a previously developed back-calculation model to estimate number and prevalence rates (per 10000) of undiagnosed HIV infections by exposure group at national and subnational levels. Belgium consists of three regions: Flanders, Brussels-Capital Region and Wallonia. We produced estimates for Brussels-Capital Region and Wallonia. For Flanders, we produced estimates for two sub-regional areas: the province of Antwerp and the other provinces, because Antwerp is the second largest city after Brussels. Population sizes were determined using data from the Belgian Statistical Office and surveys on sexual behaviour and drug use. RESULTS: In Belgium, in 2015, an estimated 2818 (95% confidence interval: 2494 to 3208) individuals were living with undiagnosed HIV, that is, 15% of individuals living with HIV. The Brussels-Capital Region and the province of Antwerp, which host the two biggest cities, accounted for ~60% of the undiagnosed infections, and had the highest undiagnosed prevalence rates per 10000: 12.0 (9.4 to 15.3) and 7.4 (5.6 to 9.8) respectively. Individuals with foreign nationality accounted for 56% of the total number of undiagnosed infections, and were the most affected populations in all areas in terms of undiagnosed prevalence rates. Specifically, men who have sex with men (MSM) with non-European nationality were the most affected population in the province of Antwerp (853.4 (408.2 to 1641.9) undiagnosed infections per 10000), the Brussels-Capital Region (543.9 (289.1 to 1019.1)), and the other provinces of Flanders (691.7 (235.5 to 1442.2)), while in Wallonia, it was heterosexual women with Sub-Saharan African nationality (132.2 (90.6 to 178.5)). CONCLUSIONS: Geographic areas hosting the biggest cities in Belgium accounted for the vast majority of undiagnosed HIV infections and individuals with foreign nationality were the most affected, especially MSM with non-European nationality. This should be accounted for when tailoring prevention and testing programs. Furthermore, MSM with foreign nationality require more attention in Belgium, and certainly more generally in Europe.

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.

Second brazilian consensus on the treatment of advanced prostate cancer: a SBOC-SBU-SBRT panel review

ABSTRACT Prostate cancer is the second most common cancer and the fifth leading cause of cancer deaths. In Brazil, it is likewise the second most common cancer among men, second only to non-melanoma skin cancers. The aim of this consensus is to align different opinions and interpretations of the medical literature in a practical and patient-oriented approach. The first Brazilian Consensus on the Treatment of Advanced Prostate Cancer was published in 2017, with the goal of reducing the heterogeneity of therapeutic conduct in Brazilian patients with metastatic prostate cancer. We acknowledge that in Brazil the incorporation of different technologies is a big challenge, especially in the Sistema Único de Saúde (SUS), which allows for the disparity in the options available to patients treated in different institutions. In order to update the recommendations and to make them objective and easily accessible, once more a panel of specialists was formed in order to discuss and elaborate a new Brazilian Consensus on Advanced Prostate Cancer. This Consensus was written through a joint initiative of the Brazilian Society of Clinical Oncology (SBOC) and the Brazilian Society of Urology (SBU) to support the clinical decisions of physicians and other health professionals involved in the care of patients with prostate cancer.
