Patients will be evaluated for inclusion after finishing first-line therapy, or after a sufficient amount of treatment in first-line, and a sufficient respons (VGPR). Eligible performed regimens are defined in the protocol. All patients will perform a PET-CT, and PET-negative patients will be excluded from protocol treatment. The PET-positive patients will do a minimal residual disease (MRD-)evaluation in the bone marrow before entering treatment. After 4 28day cycles of Carfilzomib-Revlimid-Dexamethason, a new MRD and a new PET-CT will be performed, as measures of outcome. Patients will continue treatment as written in the protocol.
A PET-CT will be performed on patients with myeloma after a standard first-line treatment. The PET-positive patients will receive 4 cycles of Carfilzomb-Revlimid-Dexamethason (KRd), before a new PET-CT will be performed.
