ABSTRACT
El cribado de cáncer de páncreas en población de alto riesgo puede mejorar la supervivencia. Sin embargo, hay pocas referencias sobre su aplicabilidad y hallazgos en la práctica clínica habitual. Nuestro objetivo es evaluar los hallazgos de las pruebas de cribado de cáncer de páncreas en individuos de alto riesgo en la práctica clínica y describir las variables asociadas a la presencia de lesiones relevantes. Este es un estudio observacional prospectivo en el que se seleccionaron pacientes con alto riesgo de cáncer de páncreas, según los criterios del Consorcio Internacional de Cribado de Cáncer de Páncreas. Se analizaron variables demográficas, presencia de factores de riesgo de cáncer páncreas y los hallazgos de las pruebas. Posteriormente se compararon pacientes que presentan lesiones relevantes con aquellos sin hallazgos. De 70 pacientes de alto riesgo, 25 cumplieron los criterios de cribado. El síndrome hereditario más frecuente fue el cáncer de mama y ovario hereditario (60%). En once individuos (44%) se identificaron hallazgos y en tres (12%) fueron relevantes: dos tumores papilares mucinosos intraductales y un tumor sólido localizado. La mutación en BRCA2 fue la más frecuente en lesiones significativas (66,7% vs 30%, p=0,376) sin encontrar asociación con diabetes ni tabaquismo (0 vs 18 %, p=0,578 y 0 vs 4,5%, p=0,880 respectivamente). En conclusión, las pruebas de cribado permiten detectar lesiones en estadio precoz o resecables en un importante porcentaje de población de alto riesgo seleccionada. Los hallazgos más relevantes fueron en los pacientes pertenecientes al síndrome de cáncer de mama y ovario hereditario.
Pancreatic cancer surveillance can improve outcomes in high-risk individuals. However, little is known about its applicability and findings in routine clinical practice. Our aim was to evaluate findings on screening tests in high-risk individuals in a clinical practice setting and to analyze factors associated with the presence of relevant pancreatic lesions. We developed a prospective observational study of pancreatic cancer high risk patients that meet criteria of surveillance from the International Cancer of the Pancreas Screening Consortium. The demographic variables, other risk factors and imaging findings are collected. Patients with significant findings are compared to those without noteworthy findings. Of 70 high-risk individuals, 25 fitted the criteria for pancreatic cancer surveillance. The most frequent condition was hereditary breast and ovarian cancer syndrome (60%). We identified eleven abnormal imaging findings (44%) and three of them (12%) were relevant: two intraductal papillary mucinous neoplasms and one localized pancreatic neoplasm. BRCA2 mutation was more frequent in patients with significant lesions (66.7% vs 30%, p=0.376) but smoking and diabetes were not associated with relevant findings (0 vs 18 %, p=0.578 and 0 vs 4.5%, p=0.880 respectively). Screening test could detect early-stage or resectable lesions in a significant in a significant percentage of the selected high-risk population. The most relevant findings were in patients belonging to hereditary breast and ovarian cancer syndrome.
