“…Brazil has the potential to be a leading example in the region, drawing upon examples of pilot CRC screening programs available abroad (Khuhaprema et al, 2014; Seeff and Rohan, 2013), and in-country (Perez et al, 2008). …”

“…Despite Brazil’s federally mandated Unified Health System with its network of basic health units, which offer comprehensive primary care services, the country does not have a national policy or government program that addresses CRC prevention and control (Paim et al, 2011; Pan-American Health Organization, 2013). Since 2002, INCA has recommended an annual FOBT for asymptomatic people aged 50 years or older and colonoscopy in case of a positive screening test (Instituto Nacional do Câncer, 2002); however, very little data about CRC screening rates are available (Coy, 2013; Perez et al, 2008; Schmidt et al, 2011). …”

In Brazil, colorectal cancer (CRC) is the fourth most common cause of cancer-related death among men, and the third most common among women. We aimed to examine CRC screening-related knowledge, attitudes, and practices among physicians and nurses working in Brazil’s network of health units, and to describe the capacity of these units for CRC screening. In 2011, 1600 health units were randomly selected from all 26 states and the Federal District. One coordinator and one health care provider were selected for the interview. Response rates were 78% for coordinators, 34% for physicians, and 65% for nurses. The Brazilian National Cancer Institute (INCA) recommendations for CRC screening were not often used in the health units, but screening outreach and use of CRC exams were more common in units that were using them. Physicians and nurses differed in most characteristics, and in their knowledge, attitudes, and practices of CRC screening. Forty-seven percent of physicians reported not conducting CRC screening compared to 65% of nurses. Fecal occult blood test was most often used by physicians and nurses, but fewer physicians than nurses perceived this exam as very effective in reducing CRC mortality. Physicians’ gender, years since graduation, and geographical region of practice in Brazil were associated to CRC screening practice. The findings may reflect the low influence of INCA CRC screening recommendations, physicians receiving their medical education when CRC burden in Brazil was of low concern, and the lack of CRC screening capacity in some regions of Brazil.

“…15 in a study carried out in the united states, the highest proportional reduction in colorectal cancer mortality between 1975 and 2000 was attributed to screening, which is becoming more common, mainly among developed countries, because of the burden of this disease within the 3 main types of cancer in the world. 17 however, in less-developed regions of Brazil, the predictions reveal increases in rates, which could be a consequence of inequities in the access to early detection services. 7 the opportunistic screening model is currently in operation in the majority of the country.…”

INTRODUCTION: Colorectal cancer (CRC) is an important pathology characterized by tumors in colorectal segments. Colonoscopy is the gold standard of CRC detection, but it is very expensive. Then, new methods are required for CRC screening to reduce mortality and improve the cost-benefit ratio. Objective: Evaluate the efficacy of a questionnaire (QSSA) based on signs and symptoms of CRC. METHODS: The QSSA was answered by 40 patients, before the colonoscopy procedure. The patients were divided into two groups: group I, with 20 patients showing positive result in the questionnaire, and group II, with 20 people showing negative result in the questionnaire. Colonoscopy was considered positive when presenting neoplasm or its precursor. The result was statistically analyzed by Fischer's exact test and sensitivity calculation. RESULTS: The results showed 14 positive and 26 negative colonoscopies. Group I had 9 positive and 11 negative colonoscopies and Group II, 5 positive and 15 negative (p=0.20) colonoscopies. The questionnaire presented sensitivity of 64.2%. CONCLUSION: The use of this questionnaire based on signs and symptoms of CCR alone was not effective in CCR screening.
INTRODUÇÃO: O câncer colorretal (CCR) é uma importante afecção caracterizada pela presença de tumores localizados no colón ou reto. A colonoscopia, padrão ouro na detecção do CCR, demanda alto custo. Assim, há necessidade de métodos de triagem eficazes, visando um melhor custo beneficio na diminuição da mortalidade do CCR. OBJETIVO: Avaliar a efetividade de um questionário de sinais, sintomas e antecedentes (QSSA) em predizer o CCR. Métodos: O QSSA foi aplicado a 40 pacientes, momentos antes da realização do exame colonoscópico, no intuito de compor dois grupos: grupo I formado pelos 20 primeiros que apresentassem o QSSA positivo, e grupo II formado pelos 20 primeiros com QSSA negativo. A colonoscopia positiva foi aquela com achado de neoplasia ou lesões precursoras do CCR. O resultado foi submetido à análise estatística através do Teste Exato de Fischer e do cálculo da sensibilidade, especificidade, acurácia e valores preditivos positivos e negativos. RESULTADO: Observaram-se 14 colonoscopias positivas e 26 colonoscopias negativas, assim distribuídas: grupo I, 9 positivas e 11 negativas; grupo II, 5 positivas e 15 negativas (p=0,20). O questionário apresentou sensibilidade de 64,2%. CONCLUSÃO: A utilização de um questionário de sinais, sintomas e antecedentes usado isoladamente não mostrou eficácia no rastreamento de lesões neoplásicas
