Background: The concept of significant polyps and early colorectal cancer encompasses complex polyps not amenable to routine snare polypectomy or where malignancy cannot be excluded. The assessment and management of these lesions is contentious and increasingly important due to the significant risk of over- or undertreatment.
Objective: Following the recommendations of the Significant Polyps and Early Colorectal Cancer National Program, we implemented a dedicated multidisciplinary team meeting and analyzed the influence on patient outcomes.
Design: This was a retrospective study using a prospectively collected database of patients discussed at the dedicated multidisciplinary team meeting.
Settings: This study was conducted in a single tertiary-care center.
Patients: Consecutive patients with significant polyps and early colorectal cancer were identified either through the Bowel Cancer Screening Program or colonoscopy for symptomatic patients.
Main Outcome Measures: Proportions of patients who had organ preservation, and secondary treatment and recurrence rate served as outcome measures.
Results: Overall, 135 patients discussed at the dedicated multidisciplinary team meeting were included, with a median age of 71 years. Median size of the lesions was 25 mm, and 39% were in the rectum. Patients were discussed either after the lesion was removed during the initial colonoscopy (n = 38), of whom 16 (42%) had unexpected cancer, or had no initial treatment with subsequent case review (n = 97). Of these 97 patients, 46 underwent endoscopic excision (26% cancer), 20 trans-anal excision (10% cancer), 23 primary surgical resection (35% cancer), and 8 had no treatment. In 104 (82%) patients, organ preservation was achieved. Secondary surgery was required in 7 of 104 (6.7%) patients after local excision due to radical treatment of high-risk T1 lesions, local recurrence, or patients' decisions. The cumulative hazard estimates for recurrence after a median follow-up of 18.5 months was less than 10% for both benign and malignant lesions.
Limitations: This study was limited by its relatively small sample size and single-center setting.
Conclusions: A dedicated multidisciplinary team meeting improved the management of significant polyps and early colorectal cancer, safely refining organ preservation for patients, with low recurrence rates. See Video Abstract at http://links.lww.com/DCR/B826.
Manejo De Specc Plipo Complejo Y Cncer Colorrectal Temprano Es Optimizado Mediante La Implementacin De Reuniones De Un Equipo Multidisciplinario Especializados Lecciones Aprendidas Del Programa Nacional Del Reino Unido: ANTECEDENTES:El concepto de pólipos complejos y cáncer colorrectal temprano abarca engloba pólipos avanzados que no es posible la reseccion endoscopica rutinaria, o aquellos en los que no se puede excluir malignidad. La evaluación y el manejo de estas lesiones es controversial y cada vez más importante debido al riesgo significativo de ser tratadas o no.OBJETIVO:Siguiendo las recomendaciones del Programa Nacional de Pólipos Complejos y Cáncer Colorrectal Temprano, implementamos reuniónes del equipo multidisciplinario especializado y analizamos el impacto en los resultados de los pacientes.DISEÑO:Estudio retrospectivo sobre una base de datos recopilada prospectivamente de los pacientes discutidos en la reunión del equipo multidisciplinario especializado.AJUSTE:Este estudio se realizó en un centro de atención terciaria.PACIENTES:Pacientes consecutivos con pólipos complejos y cáncer colorrectal temprano identificado a través del Programa de detección de cáncer intestinal o colonoscopia para pacientes sintomáticos.PRINCIPALES MEDIDAS DE RESULTADO:Proporción de pacientes que tuvieron preservación de órganos, tratamiento secundario y tasa de recurrencia.RESULTADOS:En total, se incluyeron 135 pacientes discutidos en la reunión del equipo multidisciplinario especializado dedicada, con una media de edad de 71 años. El tamaño medio de las lesiones fue de 25 mm y el 39% estaban en el recto. Se discutio de los pacientes después de que se resecara la lesión durante la colonoscopia inicial [n = 38, de los cuales 16 (42%) tenían un cáncer imprevisto] o no recibieron tratamiento de inicio, con revisión posterior del caso (n = 97). De estos, 46/97 fueron sometidos a resección endoscópica (26% cáncer), 20/97 resección transanal (10% cáncer), 23/97 resección quirúrgica primaria (35% cáncer) y 8/97 no recibieron tratamiento. En 104 (82%) pacientes, se logró la preservación de órgano. Cirugía secundaria fue requeria en 7/104 (6,7%) pacientes después de la resección local debido a tratamiento radical de lesiones T1 de alto riesgo, recidiva local o decisión del paciente. Las estimaciones de riesgo acumulativo de recurrencia después de una media de seguimiento de 18,5 meses fue inferior al 10% tanto para las lesiones benignas como para las malignas.LIMITACIONES:Tamaño de muestra relativamente pequeño y entorno de un solo centro.CONCLUSIONES:La Reunion del equipo multidisciplinario especializado mejoró el manejo de los pólipos complejos y cáncer colorrectal temprano, refinando de manera segura la preservación de órganos para los pacientes, con bajas tasas de recurrencia.

Colorectal cancer (CRC) is a prevalent malignant tumor worldwide, with a high mortality rate due to its complex etiology and limited early screening techniques. This study aimed to identify potential biomarkers for early detection of CRC utilizing targeted metabolite profiling of platelet-rich plasma (PRP). Based on multiple reaction monitoring (MRM) mode, liquid chromatography tandem mass spectrometry (LC-MS/MS) analysis identified metabolites in PRP collected from patients with CRC (n = 70) and healthy controls (n = 30).

Importance: Research indicates that social drivers of health are associated with cancer screening adherence, although the exact magnitude of these associations remains unclear.
Objective: To investigate the associations between individual-level social risks and nonadherence to guideline-recommended cancer screenings.
Design, Setting, And Participants: This cross-sectional study used 2022 Behavioral Risk Factor Surveillance System data from 39 US states and Washington, DC.

This essay focuses on the ethical considerations and implications of providing a universal multi-cancer screening test as the best approach to reduce societal cancer burden in a society with limited funds, resources, and infrastructure. With 1.9 million cancer diagnoses each year in the United States, with 86% of all cancers diagnosed in individuals over the age of 50, and with screening tools approved for only four cancer types (breast, cervical, colorectal, and lung cancer), it seems that a multi-cancer screening test to detect most cancer early that is easy to administer, and is accurate and cost-effective, would be worth considering.

Background: Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) combined with serum carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) levels to evaluate the efficacy of colorectal cancer liver metastasis (CRCLM) treatment is still rare.
Purpose: To investigate the predictive value of DCE-MRI combined with serum CEA and CA 19-9 concerning the efficacy of comprehensive treatment for CRCLM.
