ABSTRACT Background: Early-onset colorectal cancer (EO-CRC) incidence has increased significantly worldwide in recent years, and these individuals frequently have advanced disease at the time of diagnosis. This study examines the clinicopathological characteristics of EO-CRC cases diagnosed at an academic healthcare center in Spain. Methods: A retrospective record review study of patients diagnosed with EO-CRC from 2010 to 2021 was performed. Clinical and pathological data were collected. Results: A total of 101 patients were included. The majority of cases (75.3%) were diagnosed in the age group between 40 and 49 years, specifically within the subgroup of 46-49 years. A family history of colorectal cancer was found in 23% of patients. Left-sided tumors were more common (43.6%), and most patients were diagnosed at advanced stages (34.7% at stage III and 32.7% at stage IV). The majority of patients (94.1%) were symptomatic, with rectal bleeding being the most prevalent clinical presentation. The most frequent histological type was moderately differentiated adenocarcinoma (44.6%). KRAS mutant tumors were found in 18.8% and BRAF mutant tumors in 11.9%. 67.3% had microsatellite stability. Tumor recurrence occurred in 24.8% of the patients, while 27.7% of the patients died. Conclusion: From 2010 to 2021, EO-CRC accounted for 3% of all colorectal cancer cases. To improve early diagnosis and treatment, physicians should maintain a high suspicion of red flag symptoms in young patients. To decrease EO-CRC morbidity and mortality, starting diagnostic screening tests at age 45 should be considered.

RESUMO Contexto: A incidência de câncer colorretal de início precoce (CCR-IP) tem aumentado significativamente em todo o mundo nos últimos anos, e esses indivíduos frequentemente apresentam doença avançada no momento do diagnóstico. Este estudo examina as características clinicopatológicas dos casos de CCR-IP diagnosticados em um centro de saúde acadêmico na Espanha. Métodos: Realizado um estudo retrospectivo de revisão de prontuários de pacientes diagnosticados com CCR-IP de 2010 a 2021. Dados clínicos e patológicos foram coletados. Resultados: Foram incluídos um total de 101 pacientes. A maioria dos casos (75,3%) foi diagnosticada na faixa etária entre 40 e 49 anos, especificamente dentro do subgrupo de 46 a 49 anos. Histórico familiar de câncer colorretal foi encontrado em 23% dos pacientes. Tumores do lado esquerdo foram mais comuns (43,6%), e a maioria dos pacientes foi diagnosticada em estágios avançados (34,7% no estágio III e 32,7% no estágio IV). A maioria dos pacientes (94,1%) apresentava sintomas, sendo o sangramento retal a apresentação clínica mais prevalente. O tipo histológico mais frequente foi adenocarcinoma moderadamente diferenciado (44,6%). Tumores com mutação KRAS foram encontrados em 18,8% e tumores com mutação BRAF em 11,9%. 67,3% apresentavam estabilidade de microssatélites. A recorrência do tumor ocorreu em 24,8% dos pacientes, enquanto 27,7% dos pacientes morreram. Conclusão: De 2010 a 2021, o CCR-IP representou 3% de todos os casos de câncer colorretal. Para melhorar o diagnóstico precoce e o tratamento, os médicos devem manter uma alta suspeita de sintomas de alerta em pacientes jovens. Para diminuir a morbidade e a mortalidade do CCR-IP, a consideração de iniciar exames de triagem diagnóstica aos 45 anos deve ser considerada.

Abstract Introduction: Patients with inflammatory bowel disease (IBD) have a higher risk of developing gastrointestinal tumors, the adenocarcinoma is the most frequently associated, and neuroendocrine tumor (NET) the most rare. Clinical cases: We present two patients, one with Crohn's disease and the other with ulcerative colitis, who present nonspecific symptoms, and after resection of an intestinal lesion, a gastrointestinal NET (GINET) is diagnosed. Discussion and conclusion: The GINET have an insidious clinic and these can be confused with those of the IBD. There could be an association between both pathologies; an important role of the chronic intestinal inflammatory process is suggested. The best treatment for GINET is the resection.

Resumen Introducción: Los pacientes con enfermedad inflamatoria intestinal (EII) tienen mayor riesgo de desarrollar neoplasias gastrointestinales y el adenocarcinoma es el relacionado con más frecuencia y el tumor neuroendocrino (TNE) el más raro. Caso clínico: Se presentan los casos de dos pacientes, uno con enfermedad de Crohn y otro con colitis ulcerosa, que cursan con clínica inespecífica, y tras resección de la lesión intestinal se diagnostica un TNE gastrointestinal (TNEGI). Discusión y conclusiones: Los TNEGI tienen una clínica insidiosa y pueden confundirse con los de la EII. Es posible un nexo entre ambas entidades, lo que sugiere un papel importante del proceso inflamatorio crónico intestinal. El tratamiento de elección de los TNEGI es la resección.

Background and objectives: Concerns impact the quality of life for patients with inflammatory bowel disease (IBD). We attempted to identify the concerns of IBD patients in our practice, and to assess the applicability of the Rating Form of IBD Patients Concerns (RFIPC) questionnaire to Spanish patients. Patients and methods: One hundred and thirty-one patients seen in our practice filled out the Spanish version of RFIPC. The questionnaire's reliability, validity, and discriminating power were analyzed. Results: The total score was 46.93, with a standard deviation (SD) of 21.475. Primary concerns included: "having an ostomy bag", "effects of medication", "developing cancer", "energy level", and "uncertain nature of disease". Female patients scored higher on total RFIPC and on most items. Cronbach's alpha was 0.924. A good correlation was seen between two consecutive answers for 37 patients; the Spearman's coefficient was 0.842 (p < 0.001), and the intraclass correlation coefficient (ICC) was 0.775 (p < 0.001). Correlation was also found between RFIPC and both the IBDQ-32 emotional domain (0.413, p < 0.001) and anxiety scale (0.543, p < 0.001). Conclusions: The RFIPC questionnaire may be administered to Spanish patients.

Antecedentes y objetivos: las preocupaciones influyen en la calidad de vida de los pacientes con enfermedad inflamatoria intestinal (EII). Pretendemos identificar las preocupaciones de los pacientes con EII que atendemos en nuestra consulta y comprobar si el Rating Form of IBD Patients Concerns (RFIPC) es un cuestionario aplicable a los pacientes españoles. Pacientes y métodos: ciento treinta y un pacientes atendidos en la consulta contestaron la versión española del RFIPC. Se ha estudiado la fiabilidad, validez y capacidad discriminadora del cuestionario. Resultados: la puntuación total fue 46,93 con desviación estándar (DS) de 21,475. Las preocupaciones principales fueron: "que me coloquen una bolsa", "reacciones a medicamentos", "padecer cáncer", "vitalidad" y "situación incierta de la enfermedad". Los pacientes de sexo femenino puntuaron más alto en el RFIPC y en la mayoría de los ítems. El valor alfa de Cronbach fue 0,924. Se comprobó una buena correlación entre dos respuestas consecutivas de 37 pacientes, Spearman 0,842 (p < 0,001) y coeficiente de correlación intraclase (CCI) 0,775 (p < 0,001). También hubo correlación entre el RFIPC y el dominio emocional del Inflammatoy Bowel Disease Questionnarie (IBDQ) 32 0,413 (p < 0,001) y la escala de ansiedad 0,543 (p < 0,001). Conclusiones: el cuestionario RFIPC puede aplicarse a los pacientes españoles.

Introduction: Infliximab (IFX) therapy intensification in ulcerative colitis (UC) is more common than established in pivotal studies. Objectives: To establish the frequency and form of intensification for UC in clinical practice, as well as predictors, and to compare outcomes between intensified and non-intensified treatment. Methods: A retrospective study of 10 hospitals and 144 patients with response to infliximab (IFX) induction. Predictive variables for intensification were analyzed using a Cox regression analysis. Outcome, loss of response to IFX, and colectomy were compared between intensified and non-intensified therapy. Results: Follow-up time from induction to data collection: 38 months [interquartile range (IQR), 20-62]. Time on IFX therapy: 24 months (IQR, 10-44). In all, 37% of patients required intensification. Interval was shortened for 36 patients, dose was increased for 7, and 10 subjects received both. Concurrent thiopurine immunosuppressants (IMM) and IFX initiation was an independent predictor of intensification [Hazard ratio, 0.034; p, 0.006; CI, 0.003-0.371]. In patients on intensified therapy IFX discontinuation for loss of response (30.4% vs. 10.2%; p, 0.002), steroid reintroduction (35% vs. 18%; p, 0.018), and colectomy (22% vs. 6.4%; p, 0.011) were more common. Of patients on intensification, 17% returned to receiving 5 mg/kg every 8 weeks. Conclusions: Intensification is common and occasionally reversible. IMM initiation at the time of induction with IFX predicts non-intensification. Intensification, while effective, is associated with poorer outcome.

Introducción: la intensificación del tratamiento con infliximab (IFX) en la colitis ulcerosa (CU) es más frecuente de lo establecido en estudios pivotales. Objetivos: establecer la frecuencia y forma con la que intensificamos en CU en práctica clínica, los factores predictores y comparar la evolución entre los pacientes con tratamiento intensificado y no intensificado. Métodos: estudio retrospectivo de 10 hospitales y 144 pacientes con respuesta a la inducción con IFX. Se analizaron variables predictoras de la intensificación con análisis de regresión de Cox. Se comparó la evolución, pérdida de respuesta a IFX y colectomía según tratamiento intensificado o no intensificado. Resultados: tiempo de seguimiento desde la inducción hasta la recogida de datos: 38 meses [rango intercuartil (RIC) 20-62]. Tiempo de tratamiento con IFX: 24 meses (RIC, 10-44). El 37% de los pacientes requirió intensificación. Se acortó el intervalo en 36pacientes, se aumentó la dosis en 7, ambas en 10. La intro-ducción simultánea de inmunosupresores tiopurínicos (INM) e IFX predijo la intensificación de forma independiente [Hazard ratio (HR) 0,034 p 0,006 IC 0,003-0,371]. En los pacientes con tratamiento intensificado fue más frecuente la suspensión de IFX por pérdida de respuesta (30,4% vs. 10,2% p 0,002), la reintroducción de corticoides (35% vs. 18%, p 0,018) y la colectomía (22% vs. 6,4% p 0,011). El 17% de los pacientes intensificados volvió a recibir 5mg/kg cada 8 semanas. Conclusiones: la intensificación es frecuente y en ocasiones reversible. La introducción del INM en el momento de la inducción con IFX predice la no intensificación. La intensificación, aunque eficaz, se asocia a una peor evolución.
