Abstract
El cáncer renal de células claras (ccRCC) es un tumor peculiar caracterizado por estar muy vascularizado y ser muy immunogénico. Debido a estas características, el tratamiento sistémico el cáncer renal se base en el uso de tanto bloqueadores del punto de control inmunológico (ICB) y antiangiogénicos (AA). Actualmente, las combinaciones de ICB, con bien otro ICB o bien un antiangiogénico, son el estándar de tratamiento de primera línea para el ccRCC avanzado. A pesar de que los ICB proporcionan respuestas duraderas, hasta un 20% de pacientes serán desafortunadamente refractarios a los ICB. Además, un porcentaje no despreciable de pacientes desarrollará eventos adversos graves de origen inmunomediado (irAEs). Por ello, resulta necesaria una mayor comprensión de los mecanismos moleculares de respuesta y resistencia a los ICB, de cara al desarrollo de biomarcadores que nos permitan guiar las decisiones terapéuticas...
Clear-cell RCC is a unique tumour characterised by high vascularization and immunogenicity. Based on these features, the systemic therapy of metastatic RCC (mRCC) relies on the use of immune checkpoint blockers (ICB) and antiangiogenics (AA). Currently, ICB combinations with either another ICB or AA are the standard of care in first-line setting for advanced clear-cell RCC. ICB can provide long-term responses; however, only a small subset of patients will benefit, and up to 20% of ccRCC patients will be refractory to ICB. Further, a non-negligible percentage of patients will develop severe immune-related adverse events (irAEs). Thus, a better understanding of the molecular mechanisms of response and resistance to ICB is needed to develop a biomarker-based approach for treatment selection...
