What Is The Latest Treatment For Multiple Myeloma?
The last decade has seen a lot of advancement in the intervention of multiple myeloma , thus improving the selection of the patients . Chemotherapyand radical cell transplantation are the linchpin of treatment . The commonly used drug are thalidomide , lenalidomide , bortezomib , melphalan , cyclophosphamide , prednisone , and Dexone . In the preceding few age , Modern drug including pomalidomide , carfilzomib , ixazomib , daratumumab , elotuzumab , and panobinostat have been approved by FDA , which have increased the horizon of multiple myeloma treatment . These drugs can be given as a single therapy or combination therapy.(1 )
The common combination therapy are bortezomib , lenalidomide , Hexadrol ( VRD ) , bortezomib , thalidomide , Dexone ( VTD ) , bortezomib , cyclophosphamide , dexamethasone ( VCD ) , lenalidomide plus Dexone ( Rd ) , melphalan , Orasone , thalidomide ( MPT ) , bortezomib , melphalan , Liquid Pred ( VMP ) , carfilzomib , lenalidomide , Oradexon ( KRd ) .
The phase angle of multiple myeloma discussion included initial therapy , theme cell transplantation ( if patient is eligible ) and maintenance therapy , in addition to treating relapse cases .
Initial Therapy : Earlier melphalan based combination therapy was prevalent ; however , it has not been exchange by bortezomib and lenalidomide based drug combinations . Initial therapy is given for 4 cycles before the patient is considered for root word cell transplant . patient who are not eligible for stem cell transplant are given additional 8 - 12 cycles of initial therapy . VRD or VTD are the preferred regime for stock and average risk patients ; KRd is the best-loved regime for high danger patients , while Rd is the preferred regimen for standard risk and VCD for intermediate risk frail or elderly affected role who are ≥75 years of age.(2 )
Maintenance Therapy- Lenalidomide is the preferred alternative for maintenance in received risk patient ; while bortezomib or bortezomib based maintenance therapy for 1 - 2 years is preferred for intermediate peril patients . High risk patients are given carfilzomib or bortezomib based maintenance therapy for 2 years.(3 )
discourse For Relapse- Treating relapsed case of multiple myeloma is complicated . dissimilar combinations and regimens have to be tried . Almost all patients fall back after initial therapy , stem mobile phone transplantation and upkeep therapy after 4 years and approximately after 2.5 years without stem cellular phone transplantation . Relapsed and refractory cases can be treated with bortezomib and lenalidomide based regimens or new drugs based regimens , which admit carfilzomib , pomalidomide , elotuzumab , panobinostat , ixazomib and daratumumab .
Although , these drugs are FDA approve , the treatment of multiple myeloma varies from country to country and depend on the availability of the drug in that exceptional country .
Diagnosis For Multiple Myeloma
The symptomatic measure of multiple myeloma include :
The work up required for multiple myeloma let in CBC , serum calcium , serum creatinine , serum FLC assay , blood serum and urine protein electrophoresis with immunofixation , andbone marrowexamination . Imaging technique used areCT , FDG - PET / CT , andMRI .
