17 Cambio en el paradigma de clasificación y tratamiento de los tumores
Paradigma clásico Toxic, non-selective chemotherapy Targeted therapy The wider therapeutic index, direct product of development of molecular biology of 1980s Paradigm of future Integration of molecular diagnostics with targeted therapy – personalised treatment Lugar del Tumor Histología Biología Molecular Perfiles Moleculares Slide 9: Discussion Points Over the past 50 years (and in particular the past 2 decades) there have been many fundamental changes in the field of oncology. One important change has been the increased focus on understanding tumours at the molecular level, which has major implications for both diagnostics and therapeutics. It has been known for quite some time that cancer is not a single disease; rather, it is a family of diseases, many of which can kill. As technology advances, so does our understanding of the true diversity of cancer. Years ago, cancer was diagnosed and treated primarily based on where the physician found it. This approach was not particularly successful. Like peeling an onion, our appreciation of the true diversity of cancer has, over time, extended to the microscopic level, to the molecular level, and, most recently, to the genetic level. Collectively, appreciation for the true diversity of cancer is producing a shift from the old paradigm of toxic, non-selective cytotoxic drugs selected primarily on the anatomic site of the tumor, to a new paradigm of truly integrated diagnostics and targeted therapeutics, where selection of particular therapies is based on the molecular and genetic characteristics of the tumour.

21 Tres factores a tener en cuenta antes de iniciar un Tratamiento en CRA
Elección del agente y Dosis Eficacia Óptima Manejo Efectos Secundarios Duración Tratamiento

22 RAINBOW study: Modificación de esquema terapéutico de sunitinib en CRA
Retrospective observational study of mRCC patients administered sunitinib on a 2/1 schedule* Group A (n=208) Sunitinib 50 mg/day* Switched from schedule 4/2 to 2/1 due to TEAE Group B (n=41) Schedule 2/1 ab initio due to poor clinical condition Objective Evaluate efficacy and safety of 2/1 vs 4/2 schedule Eligibility criteria Patients with advanced RCC N=276 BASEL I NE Group C (n=27) Schedule 4/2 (control) En esa línea dos trabajos interesantes Safety endpoint: Incidence of adverse events Efficacy endpoint: PFS and treatment duration *Dose reductions were possible TEAE, treatment-emergent adverse events Bracarda et al.

24 Evidencia de respuestas completas con Sunitinib
Sunitinib-treated patients: n=59; sorafenib-treated patients: n=5 Long lasting CRs can occur after TKI treatment alone or when combined with local treatment Relapsing patients responded well to further therapy Median time to CR was 12.6 months in patients receiving TKIs alone, highlighting the importance of maintaining therapy Albiges L, et al.

25 Como resultado se ha mejorado la supervivencia de los pacientes
Conclusiones… En los últimos diez años se ha conseguido identificar una nueva diana terapéutica antiangiogénica y sus grupos pronóstico Como resultado se ha mejorado la supervivencia de los pacientes La mejor estratégia terapéutica se basa en utilizar un agente único de forma óptima, no existen variables predictivas validadas Forma óptima se relaciona con la prevencion y manejo de efectos tóxicos así como mantener la dosis tolerable el maximo tiempo posible
