QUIMIOTERAPIA DE INDUCCION EN TUMORES DE CABEZA Y CUELLO TODAVIA EN DISCUSION? SEOM, SALAMANCA 2013 Ricardo Hitt CENTRO INTEGRAL ONCOLOGIA CIOCC. MADRID Ricardo Hitt 1
DISEÑO ENSAYOS CLINICOS Ensayos Fases II: en ocasiones demuestran una evidencia de beneficio en los pacientes tratados llegando a ser un tratamiento estándar sin estudios de confirmación. Ejemplos: MOPP enf Hodgkin, Glevec en Gist, BEP tumores germinales. Suelen ser estudios con población seleccionada y en centros de referencia Ricardo Hitt 2
DISEÑO ENSAYOS ENSAYOS FASES III : cuales son los objetivos actualmente? Incremento supervivencia: la mayoría de las enfermedades se tratan en 2º, 3º, ó 4º líneas Tiempo a la progresión: aplicable en tumores metastásicos Intervalo libre de enfermedad: mas real cuando se valora la Remisión Completa Preservación de órganos: válido solo en enfermedades resecables y CURABLES con cirugía. Ricardo Hitt 3
DISEÑO ENSAYOS CLINICOS META ANÁLISIS: que nivel de evidencia se puede tener en poblaciones heterogéneas? En puntuales MA se mezclan estudios diseñados para diferentes enfermedades, con pronósticos diferentes, localizaciones diversas, tratamientos dispares y conclusiones que difieren de las observadas en la práctica clínica. Ejemplo: MACH (Pignon), incluye: tumores resecables, irresecables, Laringe, Orofaringe, Cavidad Oral, Platinos, Platinos subóptimos, No Platinos, diferentes técnicas y dosis de Radioterapia, etc Ricardo Hitt 4
DISEÑO ENSAYOS CLINICOS En Tumores de Cabeza y Cuello (TCC) que esta demostrado?: Ensayos Fases II: beneficios de la inducción en centros y población seleccionada, Ejemplos: PPF, TPF + QTRT, se consiguen mejores resultados en las diferentes supervivencias. Desventajas : en ocasiones datos no reproducibles, requiere una amplia experiencia y un importante manejo de soporte. Ricardo Hitt 5
DISEÑO ENSAYOS CLINICOS ENSAYOS FASES III : datos concluyentes Tumores Resecables : EORTC, VETERANOS: la quimioterapia de Inducción seguida de Rt permite reemplazar a la cirugía en tumores de laringe e hipofaringe, logrando semejante supervivencia pero con preservación de órganos. ECOG Forastiere: QTI, RT, QTRT demuestran igual supervivencia global pero mejor tasa de preservación de laringe con QTRT y QTI. A 10 años mejoría de ILE con QTI Ricardo Hitt 6
DISEÑO ENSAYOS CLINICOS ENSAYOS FASES III : datos concluyentes Esquemas de inducción con Taxanos superior a PF clásico. Ejemplos : PPF vs PF seguido QTRT estándar (Hitt et al JCO 2005) TPF vs PF seguido de QTRT no estándar(posner and Vermonken NEJM 2007) Ricardo Hitt 7
