La tecnología optoacústica de Seno Medical podría diferenciar entre tipos de cánceres. 

SAN ANTONIO, 19 de septiembre de 2019 /PRNewswire/ -- Un artículo publicado recientemente en Radiology destaca el uso pionero de tecnología nueva de imagen, presentada por Seno Medical Instruments, Inc.® (Seno Medical), en el diagnóstico de cáncer de mama. Esta tecnología podría ofrecer a los médicos una nueva herramienta no invasiva que, no solo diferencia mejor entre cánceres de mama benignos y malignos, sino que también ayuda diferenciar entre subtipos moleculares de cáncer de mama.

El análisis de 652 masas malignas concluyó que la optoacústica de Seno Medical combinada con tecnología de ecografía (OA/US) por sus siglas en inglés ofrece el potencial de plasmar características que diferencian cánceres luminales de los clasificados como cáncer triple negativo y HER2+.

"La implicación clínica de identificar con precisión subtipos moleculares de cáncer con técnicas no invasivas de imagen podría ser significativa para las pacientes", comentó Basak E. Dogan, doctora en medicina y directora de Investigación en imagen de las mamas en UT Southwestern Medical Center. "Los subtipos moleculares ayudan a determinar el tratamiento a más de dos millones de mujeres diagnosticadas con cáncer de mama al año".

Las muestras de biopsia no siempre representan todo el tumor y están sujetas a errores de selección de muestreo. Las imágenes podrían ofrecer una evaluación mejor de todo el tumor y mejorar las estrategias de tratamiento previas y posteriores a la cirugía.

Los investigadores observaron 2055 masas de mamarias en 1972 mujeres que se sometieron a OA/US antes de la biopsia con el sistema de imagen Imagio® de Seno Medical. De las masas investigadas, 652 masas en 629 mujeres mostraron cáncer invasivo en la patología final.

Los médicos normalmente usan la ecografía a escala de grises para diagnosticar cáncer. Pero el uso la ecografía sola tiene una capacidad limitada para determinar la prognosis. OA/US, que muestra funciones morfológicas y funcionales tales como los vasos sanguíneos internos, el rubor y la hemoglobina, contribuyó de manera significativa a diferenciar entre subtipos de cáncer de mama y a identificar los cánceres con mayor probabilidad de crecimiento agresivo y metástasis.

"Aunque se trata de una tecnología emergente, los resultados muestran que la tecnología OA/US podría ayudar a ofrecer un diagnóstico más puntual, práctico a millones de mujeres", comentó Gisela Menezes, doctora en medicina, doctorante y directora médica de Seno Medical. "Cuando el tiempo es oro, esta tecnología podría ofrecer a los médicos y a sus pacientes la información que necesitan para preparar el plan de tratamiento adecuado".

Seno Medical Instruments, Inc. es una compañía de imágenes médicas ubicada en San Antonio, Texas, comprometida con el desarrollo y la comercialización de una nueva modalidad de diagnóstico para el cáncer: imágenes optoacústicas. El sistema de imágenes de mamas Imagio™ de Seno Medical fusiona tecnología optoacústica con ecografía (OA/US) para generar imágenes funcionales y anatómicas fusionadas en tiempo real de las mamas. Las imágenes optoacústicas ofrecen un mapa sanguíneo único en las masas mamarias gracias a la presencia o ausencia de dos indicadores distintivos del cáncer; angiogénesis y desoxigenación; junto con las imágenes intercaladas y coregistradas de la ecografía que ofrecen una imagen anatómica tradicional.
