Clinical characteristics of early-onset gastric cancer. A study in a Colombian population.

Gastric cancer is a multifactorial disease with important genetic and environmental factors. It is the fifth most common cancer in incidence, and the fourth cause of death secondary to cancer. The incidence of early-onset gastric cancer is increasing worldwide, but clinical information on these patients has not been well established. We analyzed the association between age and clinical, endoscopic, and histopathological characteristics of gastric cancer at the time of diagnosis in a Latin American population. A retrospective and descriptive cross-sectional study was carried out using the database of the Gastroenterology Service of the Clínica Foscal and Clínica Foscal Internacional in Bucaramanga, Colombia. Between January 2016 and December 2019, 259 de novo gastric cancer cases were diagnosed, of which 36 patients (13.9%) were 40 years old or younger. In patients with early-onset gastric, the prevalence of gastric cancer diagnosis was lower in men. A family history of gastric cancer or any other neoplasm was not associated with a higher prevalence of gastric neoplasms. In young patients, vomiting and ascites were more common, the preferred anatomical location was the body of the stomach, and the Borrmann IV classification and the diffuse-type histology were more likely. Our study showed an approximation of the characteristics of early-onset gastric cancer in a Latin American population, where we observed that early-onset gastric cancer has different demographic, anatomical, and histological features than late-onset gastric cancer.

Tofacitinib en el tratamiento de la colitis ulcerosa moderada a grave en Colombia: experiencia en mundo real / Tofacitinib in the treatment of moderate to severe ulcerative colitis in Colombia: Real world experience

Introducción: No hay estudios sobre eficacia de tofacitinib para colitis ulcerosa (CU) en Latinoamérica. Se plantea como objetivo describir la eficacia y seguridad, en mundo real, de pacientes con CU moderada-grave tratados con tofacitinib en nuestro medio. Materiales y métodos: Estudio observacional descriptivo multicéntrico, en pacientes con CU que recibieron tratamiento con tofacitinib en fase de inducción por 8 semanas y luego, terapia de mantenimiento, entre junio de 2019 y junio de 2022. Resultados: Treinta y cuatro pacientes adultos, 50% mujeres, edad media 38,1 (rango 22-72) años. El 76,5% presentó pancolitis y el 20,6% colitis izquierda; el 79,4% fallo a inhibidores del factor de necrosis tumoral (anti-TNF) y el 35,3% a vedolizumab; el 14,7% era naïve a terapia biológica; el 23,5% presentó previamente manifestaciones extraintestinales. Durante la inducción, el 58,8% de los pacientes alcanzaron remisión clínica, bioquímica y endoscópica. En el mantenimiento, el 76,9% de los pacientes a las 26 semanas, y el 66,6% a las 52 semanas, presentaron remisión clínica; 8 pacientes presentaron eventos adversos, ninguno cardiovascular ni tromboembólico. El 44,1% fueron dependientes de esteroides, y el 23,5% requirieron esteroides como terapia de rescate. El 38,3% requirió aumento de tofacitinib a 10mg cada 12h durante el mantenimiento. En el 17,6% se suspendió tofacitinib por ausencia de eficacia. Se incluyeron 3 pacientes en edad pediátrica, femeninas, edad media 15,3 (rango 14-17) años, 2/3 con pancolitis y 1/3 con colitis izquierda, todas con exposición previa a terapia biológica, quienes presentaron remisión clínica, biológica y endoscópica en la inducción. Conclusiones: En este primer estudio latinoamericano con tofacitinib en CU se demuestra eficacia y seguridad en el tratamiento de nuestros pacientes con actividad moderada a grave.(AU)

Introduction: There are no studies on efficacy of tofacitinib for ulcerative colitis (UC) in Latin America. The aim of this study was to describe the efficacy and safety, in the real world, of patients with moderate-severe UC treated with tofacitinib in our setting. Materials and methods: Multicenter descriptive observational study, in patients with UC who received treatment with tofacitinib in induction phase for 8 weeks and then, maintenance therapy, between June 2019 and June 2022. Results: Thirty-four adult patients, 50% female, mean age 38.1 (range 22–72) years. 76.5% pancolitis, and 20.6% left colitis. 79.4% failure to tumor necrosis factor inhibitors (anti-TNFs), and 35.3% to vedolizumab. 14.7% naïve to biologic therapy. 23.5% had previous extraintestinal manifestations. During induction, 58.8% of patients achieved clinical, biochemical and endoscopic remission. During maintenance, 76.9% of patients at 26 weeks and 66.6% at 52 weeks presented clinical remission. Eight patients presented adverse events, none of them cardiovascular or thromboembolic. 44.1% were steroid-dependent, and 23.5% required steroids as rescue therapy. 38.3% required an increase in tofacitinib to 10mg every 12h during maintenance. In 17.6% tofacitinib was discontinued due to lack of efficacy. We included three pediatric-aged female patients, mean age 15.3 (range 14–17) years, 2/3 with pancolitis and 1/3 with left colitis, all with prior exposure to biologic therapy, who had clinical, biologic and endoscopic remission at induction. Conclusions: In this first Latin American study with tofacitinib in UC, efficacy and safety are demonstrated in the treatment of our patients with moderate to severe activity.(AU)

El cáncer gástrico es una enfermedad multifactorial con importantes factores genéticos y ambientales. Es el quinto cáncer más común en incidencia y la cuarta causa de muerte secundaria al cáncer. La incidencia del cáncer gástrico de inicio temprano está aumentando en todo el mundo, pero la información clínica sobre estos pacientes no está bien establecida. Analizamos la asociación entre la edad y las características clínicas, endoscópicas e histopatológicas del cáncer gástrico al momento del diagnóstico en una población latinoamericana. Se realizó un estudio retrospectivo y descriptivo de corte transversal utilizando la base de datos del Servicio de Gastroenterología de la Clínica Foscal y Clínica Foscal Internacional en Bucaramanga, Colombia. Entre enero de 2016 y diciembre de 2019 se diagnosticaron 259 casos de cáncer gástrico de novo, de los cuales 36 pacientes (13,9%) tenían 40 años o menos. En pacientes con enfermedad gástrica de inicio temprano, la prevalencia del diagnóstico de cáncer gástrico fue menor en los hombres. El antecedente familiar de cáncer gástrico o cualquier otra neoplasia no se asoció con una mayor prevalencia de neoplasias gástricas. En pacientes jóvenes fueron más frecuentes los vómitos y la ascitis, la localización anatómica preferida fue el cuerpo del estómago, siendo más probable la clasificación de Borrmann IV y la histología de tipo difuso. Nuestro estudio mostró una aproximación a las características del cáncer gástrico de inicio temprano en una población latinoamericana, donde observamos que el cáncer gástrico de inicio temprano tiene diferentes características demográficas, anatómicas e histológicas que el cáncer gástrico de inicio tardío.

Drenaje endoscópico transgástrico de pseudoquiste pancreático en paciente pediátrico / Transgastric endoscopic drainage of pancreatic pseudocyst in a pediatric patient

Resumen Un pseudoquiste pancreático es una acumulación de líquido casi siempre estéril, rico en enzimas digestivas y jugo pancreático encapsulado en una pared de tejido fibroso y de granulación sin revestimiento epitelial, generalmente de forma ovalada o redondeada. Los pseudoquistes se pueden desarrollar por complicaciones en el páncreas que generan obstrucción o ruptura de un conducto pancreático. Se presenta el caso de un paciente masculino de 9 años con diagnóstico de pseudoquiste pancreático con crecimiento progresivo, debido a trauma abdominal cerrado. Se realizó un manejo multidisciplinario para determinar el tratamiento. Por las características del pseudoquiste, se definió realizar un drenaje endoscópico transgástrico. El procedimiento llevado a cabo es descrito en el presente texto. El paciente evolucionó satisfactoriamente.

Abstract A pancreatic pseudocyst is an accumulation of fluid that is almost always sterile and is rich in digestive enzymes and pancreatic juice that is encapsulated in a wall of fibrous tissue and granulation tissue without an epithelial lining. They are generally oval or rounded. Pseudocysts can develop from complications in the pancreas that lead to obstruction or rupture of a pancreatic duct. We present the case of a 9-year-old male patient diagnosed with a pancreatic pseudocyst with progressive growth due to closed abdominal trauma. Multidisciplinary management determined treatment. Due to the characteristics of the pseudocyst, transgastric endoscopic drainage was used, and the procedure was carried out as described herein. The patient evolved satisfactorily.

Pancreatitis crónica calcificante en un paciente con enolismo y tabaquismo pesado / Chronic calcifying pancreatitis in a patient with enolism and heavy smoking

Hombre de 62 años con enolismo crónico y tabaquismo pesado activo, síntomas de 3 meses de evolución consistente principalmente en deposiciones diarreicas amarillentas, flotantes, fétidas, 12 diarias, que no mejoran con el ayuno, lo despiertan en la noche, con meteorismo y dolor abdominal, perdida de 12 kg de peso y edemas periféricos. La tomografía de abdomen confirmo la sospecha de pancreatitis crónica e insuficiencia exocrina como causal de la diarrea crónica y esteatorrea (1). La pérdida de peso y malnutrición son hallazgos frecuentes, para el manejo se requiere de enzimas pancreáticas a más de 40.000 U con cada comida(2). El alcoholismo y el tabaquismo activo aceleran y contribuyen al progreso de calcificación (3)(4) y en esta fase hasta el 90 % de los pacientes presentaran diabetes mellitus(5).
