ABSTRACT
Abstract Background: Surveillance colonoscopy 1 year after resection of colorectal cancer is recommended by all major societies, including National Comprehensive Cancer Network and United States Multi Society Task Force. Study objectives: Our study assesses adherence to post colorectal cancer resection surveillance colonoscopy guidelines at a large tertiary care center and aims to identify reasons for non-adherence. Methods: A retrospective study was conducted for patients who underwent curative resection for colorectal cancer between January 2016 and June 2017. Adherence to surveillance colonoscopy for non-obstructed or partially obstructed colon and rectal cancers was defined as performance of colonoscopy 11-14 months and 11-15 months after surgery, respectively. Results: A total of 80 patients were identified. Mean age was 66 ± 13 years and 58% (n = 46) were males. 60% (n = 48) had colon cancer and 40% (n = 32) had rectal cancer. 69% (n = 24) of patients with colon cancer and 42% (n = 8) of patients with rectal cancer adhered to surveillance colonoscopy guidelines and the mean time to colonoscopy was 315 ± 44 days and 369 ± 103 days, respectively. The most commonly identified reasons for non-adherence to surveillance colonoscopy included metastases (10.9%) and patients' refusal to undergo surveillance (6.5%). Conclusion: Overall, post colorectal cancer resection to follow up surveillance is inadequate. There is a need to identify barriers to surveillance post colorectal cancer resection and address them.
Resumo Introdução: A colonoscopia de rastreamento um ano após a ressecção do câncer colorretal é recomendada por todas as principais sociedades, incluindo a National Comprehensive Cancer Network e a Multi Society Task Force dos Estados Unidos. Objetivos do estudo: Avaliar a adesão às diretrizes de colonoscopia de rastreamento após ressecção de câncer colorretal em um grande centro de atendimento terciário e identificar razões para a não adesão. Métodos: Um estudo retrospectivo foi realizado em pacientes submetidos a ressecção curativa de câncer colorretal entre janeiro de 2016 a junho de 2017. Adesão à colonoscopia de rastreamento em cânceres de cólon e reto não obstruídos ou parcialmente obstruídos foi definida como a realização do procedimento entre 11 a 14 meses e 11 a 15 meses após a cirurgia, respectivamente. Resultados: Um total de 80 pacientes foram identificados. A média de idade foi de 66 ± 13 anos; 58% (n = 46) eram do sexo masculino, 60% (n = 48) tinham câncer de cólon e 40% (n = 32) tinham câncer de reto. Aderência às diretrizes de colonoscopia de rastreamento foi observada em 69% (n = 24) dos pacientes com câncer de cólon e 42% (n = 8) dos pacientes com câncer retal; o tempo médio até a realização da colonoscopia foi de 315 ± 44 dias e 369 ± 103 dias, respectivamente. Os motivos mais frequentemente identificados para a não adesão à colonoscopia de rastreamento incluíram metástases (10,9%) e recusa dos pacientes (6,5%). Conclusão: De forma geral, o rastreamento após a resecção de câncer colorretal é inadequado. É necessário identificar barreiras ao rastreamento após a ressecção do câncer colorretal e abordá-las.

OBJECTIVES: Acute and/or chronic pancreatitis has been implicated as an important risk factor for pancreatic cancer; however, the incidence and temporal relationship of pancreatitis before pancreatic cancer diagnosis are unclear. We aim to understand the role and incidence of pancreatitis temporally with the development of pancreatic cancer. METHODS: A population-based study was used to investigate a temporal relationship between pancreatitis and pancreatic cancer diagnoses. Intervals of 3, 6, 12, 24, and 36 months were developed. Demographical data including age, sex, and race were also recorded and analyzed. RESULTS: A total of 50,080 patients were found to have a diagnosis of pancreatic cancer, of which 7420 (14.8%) had prior diagnoses of pancreatitis. Of those, 92% were between the ages of 40 and 89 years. African Americans had a higher rate of pancreatitis before cancer diagnosis when compared with whites (21.2% vs 14.8%, P < 0.0001). Further analysis revealed that pancreatitis occurred in 81.3% of patients 3 months before a diagnosis of pancreas cancer and 98.9% had established diagnoses of pancreatic cancer within 3 years. CONCLUSIONS: Screening of patients older than 40 years who have pancreatitis and unclear etiology of pancreatitis may be warranted, especially in African Americans and male individuals.
