Recommendations for the treatment of vulvar cancer in settings with limited resources: Report from the International Gynecological Cancer Society consensus meeting.

Introduction: Due to scant literature and the absence of high-level evidence, the treatment of vulvar cancer is even more challenging in countries facing limited resources, where direct application of international guidelines is difficult. Recommendations from a panel of experts convened to address some of these challenges were developed. Methods: The panel met in Rio de Janeiro in September 2019 during the International Gynecological Cancer Society congress and was composed of specialists from countries in Africa, Asia, Eastern Europe, Latin America, and the Middle East. The panel addressed 62 questions and provided recommendations for the management of early, locally advanced, recurrent, and/or metastatic vulvar cancer. Consensus was defined as at least 75% of the voting members selecting a particular recommendation, whereas a majority vote was considered when one option garnered between 50.0% and 74.9% of votes. Resource limitation was defined as any issues limiting access to qualified surgeons, contemporary imaging or radiation-oncology techniques, antineoplastic drugs, or funding for the provision of contemporary medical care. Results: Consensus was reached for nine of 62 (14.5%) questions presented to the panel, whereas a majority vote was reached for 29 (46.7%) additional questions. For the remaining questions, there was considerable heterogeneity in the recommendations. Conclusion: The development of guidelines focusing on areas of the world facing more severe resource limitations may improve medical practice and patient care.

Recommendations for the prevention, screening, diagnosis, staging, and management of cervical cancer in areas with limited resources: Report from the International Gynecological Cancer Society consensus meeting.

Introduction: Nearly 85% of cervical cancer new cases are diagnosed in limited resources countries. Although several strategies have been proposed to reduce the disease burden, challenges remain to provide the best possible care. We report recommendations from an expert consensus meeting convened to address from prevention to management of cervical cancer in limited resources countries. Methods: The expert panel, composed by invited specialists from 38 developing countries in Africa, Asia, Eastern Europe, Latin America, and the Middle East, convened in Rio de Janeiro in September 2019, during the Global Meeting of the International Gynecological Cancer Society (IGCS). Panel members considered the published scientific evidence and their practical experience on the topics, as well as the perceived cost-effectiveness of, and access to, the available interventions. The focus of the recommendations was on geographic regions rather than entire countries because medical practice varies considerably in the countries represented. Resource limitation was qualified as limited access to qualified surgeons, contemporary imaging or radiation-oncology techniques, antineoplastic drugs, or overall funding for provision of state-of-the-art care. Consensus was defined as at least 75% of the voting members selecting a particular answer of the multiple-choice questionnaire, whereas the majority vote was considered as 50% to 74.9%. Results: Consensus was reached for 25 of the 121 (20.7%) questions, whereas for 54 (44.6%) questions there was one option garnering between 50% to 74.9% of votes (majority votes). For the remaining questions, considerable heterogeneity in responses was observed. Discussion: The implementation of international guidelines is challenging in countries with resource limitations or unique health-care landscapes. The development of guidelines by the health care providers in those regions is more reflective of the reality on the ground and may improve medical practice and patient care. However, challenges remain toward achieving that goal at political, economic, social, and medical levels.

Treatment of Localized and Locally Advanced, High-Risk Prostate Cancer: A Report From the First Prostate Cancer Consensus Conference for Developing Countries.

PURPOSE: To generate and present survey results on important issues relevant to treatment and follow-up of localized and locally advanced, high-risk prostate cancer (PCa) focusing on developing countries. METHODS: A panel of 99 PCa experts developed more than 300 survey questions of which 67 questions concern the main areas of interest of this article: treatment and follow-up of localized and locally advanced, high-risk PCa in developing countries. A larger panel of 99 international multidisciplinary cancer experts voted on these questions to create the recommendations for treatment and follow-up of localized and locally advanced, high-risk PCa in areas of limited resources discussed in this article. RESULTS: The panel voted publicly but anonymously on the predefined questions. Each question was deemed consensus if 75% or more of the full panel had selected a particular answer. These answers are based on panelist opinion and not on a literature review or meta-analysis. For questions that refer to an area of limited resources, the recommendations considered cost-effectiveness as well as the possible therapies with easier and greater access. Each question had five to seven relevant answers including two nonanswers. Results were tabulated in real time. CONCLUSION: The voting results and recommendations presented in this article can guide physicians managing localized and locally advanced, high-risk PCa in areas of limited resources. Individual clinical decision making should be supported by available data; however, as guidelines for treatment of localized and locally advanced, high-risk PCa in developing countries have not been defined, this article will serve as a point of reference when confronted with this disease.

Consensus on Screening, Diagnosis, and Staging Tools for Prostate Cancer in Developing Countries: A Report From the First Prostate Cancer Consensus Conference for Developing Countries (PCCCDC).

PURPOSE: To generate and present the survey results on critical issues relevant to screening, diagnosis, and staging tools for prostate cancer (PCa) focused on developing countries. METHODS: A total of 36 of 300 questions concern the main areas of interest of this paper: (1) screening, (2) diagnosis, and (3) staging for various risk levels of PCa in developing countries. A panel of 99 international multidisciplinary cancer experts voted on these questions to create recommendations for screening, diagnosing, and staging tools for PCa in areas of limited resources discussed in this manuscript. RESULTS: The panel voted publicly but anonymously on the predefined questions. Each question was deemed consensus if 75% or more of the full panel had selected a particular answer. These answers are based on panelist opinion not a literature review or meta-analysis. For questions that refer to an area of limited resources, the recommendations consider cost-effectiveness and the possible therapies with easier and greater access. Each question had five to seven relevant answers including two nonanswers. The results were tabulated in real time. CONCLUSION: The voting results and recommendations presented in this document can be used by physicians to support the screening, diagnosis, and staging of PCa in areas of limited resources. Individual clinical decision making should be supported by available data; however, as guidelines for screening, diagnosis, and staging of PCa in developing countries have not been developed, this document will serve as a point of reference when confronted with this disease.

Consensus on Prostate Cancer Treatment of Localized Disease With Very Low, Low, and Intermediate Risk: A Report From the First Prostate Cancer Consensus Conference for Developing Countries (PCCCDC).

PURPOSE: A group of international urology and medical oncology experts developed and completed a survey on prostate cancer (PCa) in developing countries. The results are reviewed and summarized, and recommendations on consensus statements for very low-, low-, and intermediate-risk PCa focused on developing countries were developed. METHODS: A panel of experts developed more than 300 survey questions of which 66 questions concern the principal areas of interest of this paper: very low, low, and intermediate risk of PCa in developing countries. A larger panel of 99 international multidisciplinary cancer experts voted on these questions to create the recommendations for treatment and follow-up for very low-, low-, and intermediate-risk PCa in areas of limited resources discussed in this manuscript. RESULTS: The panel voted publicly but anonymously on the predefined questions. Each question was deemed consensus if 75% or more of the full panel had selected a particular answer.

Each question had five to seven relevant answers including two nonanswers. The results were tabulated in real time. CONCLUSION: The voting results and recommendations presented in this document can be used by physicians to support management for very low, low, and intermediate risk of PCa in areas of limited resources. Individual clinical decision making should be supported by available data; however, as guidelines for treatment for very low, low, and intermediate risk of PCa in developing countries have not been developed, this document will serve as a point of reference when confronted with this disease.

Consensus on Treatment and Follow-Up for Biochemical Recurrence in Castration-Sensitive Prostate Cancer: A Report From the First Global Prostate Cancer Consensus Conference for Developing Countries.

PURPOSE: To present a summary of the treatment and follow-up recommendations for the biochemical recurrence in castration-sensitive prostate cancer (PCa) acquired through a questionnaire administered to 99 PCa experts from developing countries during the Prostate Cancer Consensus Conference for Developing Countries. METHODS: A total of 27 questions were identified as related to this topic from more than 300 questions. The clinician's responses were tallied and presented in a percentage format. Topics included the use of imaging for staging biochemical recurrence, treatment recommendations for three different clinical scenarios, the field of radiation recommended, and follow-up. Each question had 5-7 relevant response options, including "abstain" and/or "unqualified to answer," and investigated not only recommendations but also if a limitation in resources would change the recommendation. RESULTS: For most questions, a clear majority (> 50%) of clinicians agreed on a recommended treatment for imaging, treatment scenarios, and follow-up, although only a few topics reached a consensus > 75%. Limited resources did affect several areas of treatment, although in many cases, they reinforced more stringent criteria for treatment such as prostate-specific antigen values > 0.2 ng/mL and STAMPEDE inclusion criteria as a basis for recommending treatment. CONCLUSION: A majority of clinicians working in developing countries with limited resources use similar cutoff points and selection criteria to manage patients treated for biochemically recurrent castration-sensitive PCa.

Approaching glioblastoma during COVID-19 pandemic: current recommendations and considerations in Brazil.

BACKGROUND: Cancer patients in general and glioblastoma patients, in particular, have an increased risk of developing complications from the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and reaching a balance between the risk of exposure to infection and the clinical benefit of their treatment is ideal. The aggressive behavior of this group of tumors justifies the need for a multidisciplinary team to assist in clinical decisions during the current pandemic. Brazil is now ranked #2 in the number of cases and deaths from COVID-19 pandemic, and existing disparities in the treatment of neuro-oncology patients in Brazil will challenge the clinical and surgical decisions of this population, possibly affecting global survival. OBJECTIVE: To search the literature about the management of glioblastomas during COVID-19 pandemic to guide surgical and clinical decisions in this population of patients in Brazil. METHODS: We performed a systematic search on the PubMed electronic database targeting consensus statements concerning glioblastoma approaches during COVID-19 pandemic up to July 18, 2020. RESULTS: When approaching glioblastoma during the COVID-19 pandemic, important parameters that help in the decision-making process are age, performance status, tumor molecular profile, and patient consent. Younger patients should follow the standard protocol after maximal safe resection, mainly those with MGMT methylated tumors. Aged and underperforming patients should be carefully evaluated, and probably a monotherapy scheme is to be considered. Centers are advised to engage in telemedicine and to elaborate means to reduce local infection. CONCLUSION: Approaching glioblastoma during the COVID-19 pandemic will be challenging worldwide, but particularly in Brazil, where a significant inequality of healthcare exists.

Approaching glioblastoma during COVID-19 pandemic: current recommendations and considerations in Brazil / Abordando glioblastomas durante a pandemia pelo COVID-19: recomendações atuais e considerações no Brasil

RESUMO Introdução: Pacientes com câncer, em geral, e particularmente pacientes com glioblastoma estão sob elevado risco de desenvolver síndrome respiratória aguda grave devido à infecção pelo SARS-CoV-2, e alcançar um equilíbrio entre risco de exposição à infecção e benefício clínico do tratamento seria o ideal. O comportamento agressivo desse grupo de tumores justifica a necessidade de equipe multidisciplinar para auxiliar nas decisões clínicas durante a pandemia vigente. O Brasil ocupa hoje o segundo lugar em número de casos e óbitos pela COVID-19, e as atuais disparidades no tratamento de pacientes neuro-oncológicos desafiarão as decisões clínicas e cirúrgicas dessa população, possivelmente afetando a sobrevida global. Objetivo: Guiar decisões clínicas e cirúrgicas relacionadas ao manejo de glioblastoma durante a pandemia pelo COVID-19 no Brasil por meio de pesquisa em literatura. Métodos: Busca sistemática no banco de dados eletrônico da PubMed por estudos ou consensos quanto à abordagem de glioblastoma durante a pandemia por COVID-19 até 18/07/2020. Resultado: Ao abordar o glioblastoma durante a pandemia pela COVID-19, parâmetros importantes que auxiliam no processo de tomada de decisão são idade, desempenho, perfil molecular tumoral e consentimento do paciente. Pacientes jovens devem seguir protocolo padrão após máxima ressecção cirúrgica, principalmente aqueles com metilação do promotor MGMT. Idosos e pacientes debilitados devem ser cuidadosamente avaliados, e monoterapia deve ser provavelmente considerada. Centros de saúde são orientados a utilizar-se da telemedicina e de meios para reduzir infecção local. Conclusão: A abordagem do glioblastoma durante a pandemia por COVID-19 será mundialmente desafiadora, mas particularmente no Brasil, onde ainda existe significativa inequidade no cuidado com a saúde.

Intensity-modulated radiation therapy (IMRT) versus 3-dimensional conformal radiation therapy (3D-CRT) for head and neck cancer: cost-effectiveness analysis.

BACKGROUND: A cost-effectiveness analysis of IMRT compared to 3D-CRT for head and neck cancer patients (HNCPs) was conducted in the Brazilian Public Health System. METHODS: A Markov model was used to simulate radiation therapy-induced dysphagia and xerostomia in HNCPs. Data from the PARSPORT trial and the quality-of-life study were used as parameters. The incremental cost-effectiveness ratio (ICER) and cost per quality-adjusted life-year (QALY) gained were calculated. RESULTS: At 2 years, IMRT was associated with an incremental benefit of 0.16 QALYs gained per person, resulting in an ICER of BRL 31,579 per QALY gained. IMRT was considered cost-effective when using the guideline proposed by the World Health Organization (WHO) of three times the national gross domestic product (GDP) per capita (BRL 72,195). Regarding life expectancy (15 years), the incremental benefit of IMRT was 1.16 QALYs gained per person, with an ICER of BRL 4,341. IMRT was also cost-effective using the WHO definition, which states that the maximum cost is equal to the GDP per capita (BRL 24,065). CONCLUSIONS: IMRT was considered cost-effective from the perspective of the Brazilian public health system.

RESUMO INTRODUÇÃO: Foi realizada uma análise de custo-efetividade da radioterapia com intensidade modulada de feixe (IMRT) comparada com a radioterapia conformada para pacientes com câncer de cabeça e pescoço (CCP) no contexto do Sistema Único de Saúde (SUS). MÉTODOS: Foi elaborado um modelo de Markov para comparar os custos médicos diretos e os desfechos de saúde relacionados à qualidade de vida do paciente pós-intervenção radioterápica sofrendo de xerostomia e disfagia. Com essa finalidade, foram usados os dados do estudo PARSPORT e parâmetros de qualidade de vida. Os resultados comparativos das estratégias alternativas de tratamento foram medidos pela razão de custo-efetividade incremental (RCEI). O desfecho analisado foi o de anos de vida ajustados à qualidade (QALY). RESULTADOS: Em um horizonte de tempo de dois anos, a IMRT foi associada com um benefício incremental de ganho de 0,16 QALYs por indivíduo, resultando em um RCEI de R$ 31.579 por QALY ganhado. A IMRT foi custo-efetivo, adotando-se o limite máximo de disposição a pagar, proposto pela OMS, de três vezes o PIB per capita nacional, equivalente a R$ 72.195. No horizonte de tempo de 15 anos, o benefício incremental de ganho foi de 1,16 QALYs por indivíduo, com um RCEI de R$ 4.341. A IMRT foi custo-efetivo, adotando-se o limite de disposição a pagar, proposto pela OMS, de uma vez o PIB per capita nacional, equivalente a R$ 24.065. CONCLUSÃO: A IMRT foi considerada um tratamento custo-efetivo na perspectiva do SUS.
