Background: Various colorectal cancer screening programs are thought to be responsible for the decline in colorectal cancer incidence and mortality in developed countries. However, a few recently published studies indicate that many patients do not fully complete the preplanned colorectal cancer screening. Currently, there is a lack of high-volume data examining patient compliance and its impact on the screening program results.
Objective: To assess the relationship between participation and compliance within the program and the mortality of patients who participate in the screening program.
Design: Large database cohort study.
Settings: Nationwide colorectal cancer screening program of a European Union country (Lithuania).
Patients: Data of patients aged 50 to 74 years who participated in the colorectal cancer screening program from January 2013 to December 2019 were extracted from a national database.
Main Outcome Measures: Mortality data were extracted on all persons who died from 2013 through December 2020. Patients were divided into 4 groups according to their adherence to the colonoscopy screening program.
Results: A total of 1,521,394 patients participated in the screening program. A positive fecal immunochemical test was detected for 127,503 patients (8.3%), of whom 55,202 (43.3%) proceeded with further colonoscopy. Patients who had a negative fecal immunochemical test result had the lowest mortality rates (4.9%), and patients who had a positive fecal immunochemical test result but did not undergo follow-up colonoscopy had the worst mortality rate (8.6%; p < 0.001). The logistic regression model indicated that patients with a positive fecal immunochemical test and without a subsequent colonoscopy had a significantly increased mortality risk (OR 2.18; 95% CI, 2.12-2.24; p < 0.001).
Limitations: Lack of data on timing of colonoscopy, comorbidities, lifestyle factors, or previous medical history.
Conclusions: Our study indicates that noncompliers with colonoscopy, especially women, after a positive fecal immunochemical test are at a significantly increased all-cause mortality risk. See Video Abstract .
El Impacto De La Colonoscopia En El Seguimiento De La Supervivencia En Un Programa De Deteccin Del Cncer Colorrectal, Basado En Pruebas Inmunoqumicas Fecales Un Estudio A Nivel Nacional: ANTECEDENTES:Se cree que varios programas de detección del cáncer colorrectal son responsables en la disminución de la incidencia y la mortalidad del cáncer colorrectal en los países desarrollados. Pocos estudios recientemente publicados, indican que muchos pacientes no completan el programa de detección planificado previamente del cáncer colorrectal. Actualmente, faltan datos de gran volumen que examinen el cumplimiento del paciente y su impacto en los resultados del programa de detección.OBJETIVO:Evaluar la relación entre participación y cumplimiento dentro del programa y la mortalidad de los pacientes que participaron en el programa de detección.DISEÑO:Estudio de cohorte de una gran base de datos.AJUSTE:Programa nacional de detección del cáncer colorrectal de un país de la Unión Europea (Lituania).PACIENTES:Datos de pacientes de entre 50 y 74 años que participaron en el Programa de detección del cáncer colorrectal desde enero de 2013 hasta diciembre de 2019 de una base de datos nacional.PRINCIPALES MEDIDAS DE RESULTADO:Se extrajeron datos de mortalidad de todas las personas que fallecieron desde 2013 hasta diciembre de 2020. Los pacientes se dividieron en cuatro grupos según su adherencia al programa de detección mediante colonoscopia.RESULTADOS:Un total de 1,521,394 pacientes participaron en el programa de detección. Se detectó una prueba inmunoquímica fecal positiva en 127,503 (8,3 %) pacientes, de los cuales 55,202 (43,3 %) procedieron a una colonoscopia adicional. Los pacientes con una prueba inmunoquímica fecal negativa tuvieron las tasas de mortalidad más bajas y los que tuvieron una prueba inmunoquímica fecal positiva, pero no se sometieron a una colonoscopia de seguimiento, tuvieron las peores con un 4,9 % y un 8,6 % respectivamente, p < 0,001. El modelo de regresión logística indicó que los pacientes con una prueba inmunoquímica fecal positiva y sin una colonoscopia posterior, tenían un riesgo de mortalidad significativamente mayor (OR 2,18; IC del 95 %: 2,12-2,24; p < 0,001).LIMITACIONES:Falta de datos sobre el momento de la colonoscopia, comorbilidades, factores de estilo de vida o el historial médico previo.CONCLUSIONES:Nuestro estudio indica que los que no cumplieron con la colonoscopia, especialmente las mujeres, después de una prueba inmunoquímica fecal positiva, tienen un riesgo significativamente mayor de mortalidad por todas las causas.

Objectives: Participation rates in fecal immunochemical test (FIT)-based colorectal cancer (CRC) screening differ across socio-demographic subgroups. The largest health gains could be achieved in subgroups with low participation rates and high risk of CRC. We investigated the CRC risk within different socio-demographic subgroups with low participation in the Dutch CRC screening program.

Importance: In colorectal cancer (CRC) screening, too many patients fail to receive follow-up colonoscopy after an abnormal fecal immunochemical test (FIT), and transportation is a frequently reported barrier.
Objective: To determine the outcomes and cost-effectiveness of providing a rideshare intervention to patients with abnormal FIT results.
Design, Setting, And Participants: The CRC-Simulated Population Model for Incidence and Natural History microsimulation model was used to simulate the outcomes and cost-effectiveness of a rideshare intervention to improve colonoscopy completion in a population-based CRC screening program.

Objectives: This study aims to quantify the preference of adults below 50 years of age for fecal immunochemical test (FIT) options as screening for colorectal cancer (CRC) and its disparities across different subgroups.
Methods: A discrete choice experiment (DCE) was conducted among adults aged < 50 years old in Hong Kong. A mixed logit model and latent class model were used to estimate their preference, taking into account their preference heterogeneity.

The faecal immunochemical test (FIT) is endorsed by NICE for triaging symptomatic patients referred from primary care. This prospective diagnostic accuracy study assessed the performance of FIT in detecting significant colorectal pathology among symptomatic patients referred for colonoscopy in secondary care. Between May 2023 and May 2024, FIT kits were distributed to 1296 adult patients referred for lower gastrointestinal (GI) endoscopy.
