Argumentos• El CDIS se asocia con una alta sobrevida , pero se recomienda el

tratamiento RT debido al riesgo de recurrencia (como CDIS o cáncer invasor )– El tratamiento habitual es la cirugía conservadora de la mama, seguida de

radiación

• La CC por sí sola es una opción para las personas con bajo riesgo de recidiva local

• Los factores clínicos y patológicos tradicionales no permiten identificar adecuadamente las pacientes con bajo riesgo de recurrencia después de la cirugía conservadora .

• Es necesarias la identificación de biomarcadores para mejorar la evaluación del riesgo de las pacientes con CDIS tratadas mediante cirugía conservadora.

El Score Oncotype CDIS como un predictor de recurrencia local: Análisis del estudio E5194 ECOG

• Recurrencias locales :– DCIS Score HR (per 50 units) = 2.31

(95% CI: 1.15, 4.49,p=.02)– Ajustado por la toma de TAM

• Recurrencia local invasora:– DCIS Score HR (per 50 units) = 3.68

(95% CI: 1.34, 9.62,p=.01)– No ajustado

¿Esto se puede aplicar a toda la población en general?

Objetivos del estudioObjetivos primarios

• Para evaluar si el RS se asocia con el riesgo de recurrencia local ( CDIS o invasivo ) en las pacientes tratadas con CC exclusivamente y con márgenes negativos .– Pacientes con RH + ( evaluadas por RT-PCR cuantitativa )– Todas las pacientes independientemente del estado de los RH.

Objetivos secundarios

• Para evaluar si el RS de CDIS se asoció con LR ajustada por factores clínicos y patológicos significativos

• Para evaluar si el RS de DCIS se asocia con el riesgo de :

• Recidiva local invasora

• Recidiva local como CDIS

San Antonio Breast Cancer Symposium – December 9-13, 2014

Conclusiones• El RS para CDIS (alto) se asocia con el riesgo de recidiva local in situ e invasora

en una población de pacientes con carcinoma ductal in situ puro tratada con cirugía conservadora de mama sin RT

• EL RS para CDIS mejora la estratificación del riesgo en el carcinoma ductal in situ y proporciona estimaciones individuales de riesgo de recurrencia después del tratamiento con CC exclusivamente

• Ayudar a mejorar la toma de decisiones en el CDIS

• Reducir el sobre tratamiento en aquellas pacientes con bajo riesgo de recurrencia

• Ajustar el tratamiento en mujeres con mayor riesgo de recurrencia

• Los análisis de la puntuación de CDIS en individuos tratados con BCS y la radiación se presentarán en una fecha futura
