Definición de Medicina de Precisión

• Se trata de una aproximación a la prevención de padecer una enfermedad y laprobabilidad de respuesta a los tratamientos médicos que están condicionadospor nuestros genes y el ambiente al que estamos expuestos como resultado denuestro entorno y estilo de vida.

• La integración de los datos genómicos y de otras ciencias ómicas con el conjuntode datos clínicos del paciente y su entorno, permite una práctica clínica adaptada alas características individuales de cada paciente, en lo que se denomina MedicinaPersonalizada de Precisión (MPP).

PDL-1 is prognostic in RCC

PDL-1 expression is associated with:

➢Impaired antitumor immunity

➢More aggressive disease

➢High tumor grade

➢Shorter survival

In the COMPARZ trial PDL-1+ (HS<55) was associated with worse OS in both arms (p=0.003):

➢Pazopanib: 15.1 vs 36.6 months

➢Sunitinib: 15,3 vs 27,3 months

A combined analysis of the METEOR and CABOSUN positive PD-L1 expression in Tumor Cells (TCs) had poorer

PFS and OS.
