PSMA-directed radioligand therapy

PSMA-directed radioligand therapy (RLT) emerged as therapeutic option for mCRPC. PSMA-directed RLT advantage of potentially addressing both visceral and bony micro- and macroscopic disease.

Conclusiones

● A pesar de los avances es necesario seguir desarrollando nuevos fármacos.

● Es esencial seleccionar a los pacientes con los biomarcadores adecuados (alteraciones vías reparación DNA, pérdida de PTEN, inestabilidad).

● Necesario selección de pacientes y adecuado diseño de estudios.
