A number of myeloma is a malignancy of the plasma cells. A number of myeloma develops when clonal plasma cells proliferate within the bone marrow or type extramedullary plasmacytomas. The malignant plasma cells produce excessive ranges of monoclonal protein, usually immunoglobulin G (IgG), IgM, IgA, or, very not often, IgD. A number of myeloma is related to typical indicators of finish organ harm — hypercalcemia, renal insufficiency, anemia, and bone lesions — that are collectively referred to as CRAB signs.1,2
A number of myeloma is usually preceded by monoclonal gammopathy of undetermined significance (MGUS) and smoldering myeloma (SM). MGUS is an asymptomatic situation characterised by low ranges of serum monoclonal protein and fewer than 10% clonal plasma cells within the bone marrow. SM happens when serum monoclonal protein ranges improve to larger than 3 gm/dL, urine monoclonal protein ranges improve to larger than 500 mg per 24 hours, or the bone marrow incorporates 10% to 60% clonal plasma cells. Roughly 1% of MGUS instances and 10% of SM instances per yr progress to a number of myeloma, however it’s not clear which elements decide whether or not a clonal plasma cell will turn into malignant.1–3
In 2023, an anticipated 35,730 folks will develop a number of myeloma in the USA, reflecting a rise of greater than 40% since 1990.4 This most cancers is unusual, making up roughly 1.8% of all most cancers diagnoses and 10% of all hematologic malignancies in the USA. A number of myeloma is barely extra more likely to have an effect on males than girls, and it’s most prevalent in non-Hispanic Black populations. It sometimes impacts older adults, and the median age at prognosis is 69.1,2,4
A number of myeloma mortality charges have decreased by 18% since 1994 as a result of growth of recent therapies and therapy regimens. A number of myeloma is liable for 2.1% of US most cancers deaths.4 For the 4% of people who’re identified with localized illness, through which a solitary plasmacytoma is recognized, the 5-year relative survival fee is 79.5%. The remaining 96% of sufferers have systemic a number of myeloma, which comes with a 5-year relative survival fee of 59%.1,4
A number of Myeloma Remedy
A number of myeloma therapy choices embody a number of drug sorts, reminiscent of1,5:
- The primary-in-class proteasome inhibitor bortezomib
- The following-generation proteasome inhibitors carfilzomib and ixazomib, which induce fewer off-target results and opposed occasions like peripheral neuropathy
- Immunomodulatory medicine (IMiD) reminiscent of lenalidomide, pomalidomide, and thalidomide
- The steroid drug dexamethasone
- Anti-CD38 monoclonal antibodies, together with daratumumab and isatuximab
- Different monoclonal antibodies reminiscent of elotuzumab, which targets the SLAMF7 receptor
- The chimeric antigen receptor (CAR) T-cell therapies idecabtagene vicleucel (additionally known as ide-cel) and ciltacabtagene autoleucel (additionally known as cilta-cel), which goal B-cell maturation antigen (BCMA)
- The bispecific T-cell engager (BiTE) teclistamab-cqyv
When selecting therapy for a affected person with a number of myeloma, clinicians ought to contemplate the affected person’s threat degree, comorbidities reminiscent of renal illness or neuropathy, and whether or not the affected person is a candidate for hematopoietic stem cell transplantation (HSCT).1
Danger Stratification
Affected person threat degree is usually assessed utilizing the Revised Worldwide Staging System (R-ISS). This technique stratifies sufferers with a number of myeloma into the next levels6:
- Stage I: Serum ꞵ-2 microglobulin <3.5 mg/L, serum albumin ≥3.5 g/dL, serum lactate dehydrogenase (LDH) larger than or equal to the higher restrict of regular, and standard-risk chromosomal abnormalities
- Stage II: Not R-ISS stage I or II
- Stage III: Serum ꞵ-2 microglobulin ≥5.5 mg/L and both serum LDH larger than the higher restrict of regular or high-risk chromosomal abnormalities
Excessive-risk chromosomal abnormalities embody del(17p), translocation t(4;14), and translocation t(14;16). These abnormalities needs to be detected utilizing fluorescence in situ hybridization (FISH).6
Different elements which will point out extra aggressive or high-risk illness embody6:
- Different cytogenetic abnormalities, together with monosomy 17p, 1q21 acquire or amplification, trisomies, MYC translocation, TP53 mutations, or advanced karyotype
- Excessive-risk gene expression signature
- A excessive diploma of plasma cell proliferation
- Circulating plasma cells
- Excessive serum free gentle chain (FLC)
- Renal failure
- Thrombocytopenia
- Lymphopenia
- Immunoparesis
- Extramedullary illness
- Frailty
Administration of A number of Myeloma in Transplant-Eligible Sufferers
Autologous hematopoietic stem cell transplant (HSCT) needs to be thought-about for all eligible sufferers. Basically, a affected person who undergoes HSCT ought to have enough cardiac, pulmonary, hepatic, and renal perform.1,6
Sufferers usually obtain induction remedy earlier than present process HSCT. For traditional-risk sufferers, commonplace of care consists of 4 cycles of the triplet routine VRd, which incorporates1,2,6:
- Bortezomib
- Lenalidomide
- Dexamethasone
Alternate induction remedy regimens could also be thought-about if lenalidomide shouldn’t be an possibility as a result of renal failure, elevated threat for thromboembolism, or different elements which will result in a better probability of problems. Clinicians might contemplate VTd (bortezomib, thalidomide, and dexamethasone) or VCd, additionally known as CyBorD (bortezomib, cyclophosphamide, and dexamethasone). Low-dose dexamethasone results in fewer opposed occasions and should enhance survival.2
Youthful sufferers or those that usually are not candidates for bortezomib can also be capable to use extra therapy regimens, together with VRd plus daratumumab, KRd (carfilzomib, lenalidomide, and dexamethasone), or DRd (daratumumab, lenalidomide, and dexamethasone). Nonetheless, it’s not but clear whether or not these therapy choices result in improved outcomes in contrast with VRd.2
Two-drug regimens can also be thought-about for sufferers who’ve a low efficiency standing or are frail based mostly on health ranges measured by a software such because the Worldwide Myeloma Working Group’s frailty rating calculator. This software takes into consideration age, comorbidities, and skill to hold out actions of day by day residing. If a affected person’s efficiency standing improves over the course of therapy, an extra drug could also be added to the routine.6
Sufferers with high-risk illness ought to obtain VRd plus daratumumab or KRd. KRd results in larger charges of full response (CR) and minimal residual illness (MRD) negativity for sufferers with high-risk options.1,7
Following preliminary cycles of induction remedy, stem cells are harvested. The cells may be transplanted instantly. Alternatively, the cells may be saved and used for a future autologous HSCT following a primary relapse or after the affected person’s efficiency standing improves.1,2,6
Some small research in addition to medical observations have indicated that immunotherapies like pembrolizumab could also be helpful when applied rapidly after HSCT. Preliminary trials analyzing mixture remedy with ipilimumab and nivolumab have additionally reported improved outcomes for sufferers with high-risk or relapsed myeloma. Nonetheless, some medical trials haven’t discovered the checkpoint inhibitors nivolumab and pembrolizumab to be efficient, and a number of trials combining immunotherapies with IMiDs have been discontinued after they resulted in elevated mortality.8,9 In the end, the mix of pembrolizumab, an IMiD, and dexamethasone shouldn’t be used exterior of a medical trial.10
Induction remedy is often adopted by upkeep remedy with lenalidomide for standard-risk sufferers and a proteasome inhibitor reminiscent of bortezomib for high-risk sufferers.1,2
A number of Myeloma Remedy in Transplant-Ineligible Sufferers
If HSCT shouldn’t be an possibility, sufferers sometimes obtain VRd, DRd, VCd, or VTd induction remedy for 8 to 12 cycles. Different advisable therapy choices embody KRd, VCd pus daratumumab, or a mixture of daratumumab, bortezomib, melphalan, and prednisone.1,2,6
Analysis signifies that lenalidomide probably doesn’t enhance prognosis for sufferers with high-risk a number of myeloma. Sufferers on this class ought to hunt down medical trials, when out there.6,7
Upkeep remedy consists of lenalidomide, with or with out dexamethasone. Sufferers can even obtain upkeep bortezomib or ixazomib. Frail sufferers could also be handled with lenalidomide and dexamethasone till illness development happens.1,2
In as much as 5% of instances, a number of myeloma might unfold to the lymph nodes, belly organs, pores and skin, or higher airway. Due to the rarity of this situation, medical knowledge describing efficient therapies for extramedullary illness are very restricted.11
Very not often, extramedullary illness might happen within the central nervous system (CNS) at prognosis or throughout relapse. Most systemic therapies can’t successfully eradicate myeloma cells or are not usually able to crossing the blood-brain barrier. Nonetheless, restricted knowledge point out that bendamustine and marizomib could also be efficient at treating CNS illness when mixed with radiation remedy, thalidomide, and dexamethasone. HSCT, cranial radiation, or intrathecal hydrocortisone, methotrexate, and/or cytarabine can also be choices for treating CNS illness.11
Remedy for Relapsed and Refractory A number of Myeloma
Remedy selections for relapsed myeloma are based mostly on relapse timing, response to earlier therapies, the diploma of relapse aggressiveness, and affected person efficiency standing. Particularly, a affected person is taken into account to have high-risk relapsed illness if the relapse happens inside 1 yr of induction remedy.1,2
Relapsed a number of myeloma could also be handled with numerous triplet regimens, together with2,6,8:
- VRd
- VCd, with or with out daratumumab
- VTd
- KRd
- DRd
- Daratumumab, bortezomib, and dexamethasone
- Daratumumab, pomalidomide, and dexamethasone
- Carfilzomib, pomalidomide, and dexamethasone
- Carfilzomib, cyclophosphamide, and dexamethasone
- Ixazomib, lenalidomide, and dexamethasone
- Ixazomib, cyclophosphamide, and dexamethasone
- Elotuzumab, lenalidomide, and dexamethasone
- Elotuzumab, bortezomib, and dexamethasone
- Bendamustine, lenalidomide, and dexamethasone
- Bendamustine, bortezomib, and dexamethasone
- Liposomal doxorubicin, bortezomib, and dexamethasone
- Selinexor, bortezomib, and dexamethasone
The Nationwide Complete Most cancers Community (NCCN) recommends VRd and IRd as the popular therapy regimens for sufferers with a number of myeloma following a relapse.6 The Worldwide Myeloma Working Group (IMWG) prefers DRd and KRd for sufferers with illness that’s not refractory to lenalidomide.12
If relapse happens greater than 6 months after preliminary remedy, the induction remedy routine can be utilized. Different therapy choices for sufferers who expertise a late relapse and have tried 3 prior therapies embody high-dose or fractionated cyclophosphamide, or bendamustine as a single agent or together with dexamethasone and an IMiD or proteasome inhibitor.6
Sufferers with the t(11;14) translocation can be handled with venetoclax, a BCL-2 inhibitor. Regimens containing anthracyclines could also be thought-about when relapses are aggressive.2
The NCCN’s advisable therapy choices for refractory a number of myeloma are described in Desk 1.
Desk 1. NCCN Really useful Regimens for Refractory A number of Myeloma6
New Refractory Illness | Refractory Illness Beforehand Handled With 1 Line of Remedy | Refractory Illness Beforehand Handled With 2 Traces of Remedy | Refractory Illness Beforehand Handled With 2 Traces of Remedy and With Illness Development Inside 61 Days of Preliminary Remedy | |
Bortezomib- refractory illness | DRd; KRd; a mixture of daratumumab, carfilzomib, and dexamethasone; a mixture of carfilzomib, pomalidomide, and dexamethasone; or a mixture of isatuximab, carfilzomib, and dexamethasone | Daratumumab, pomalidomide, and dexamethasone | Isatuximab, pomalidomide, and dexamethasone | Ixazomib, pomalidomide, and dexamethasone |

From the NCCN.6
A primary or extra HSCT can also be thought-about throughout relapse or development of a number of myeloma if the affected person is a candidate. Both an autologous or allogeneic transplant could also be thought-about.6
The US Meals and Drug Administration (FDA) lately authorized teclistamab-cqyv for the therapy of relapsed or refractory a number of myeloma. Teclistamab-cqyv is a BiTE that targets each CD3 on T cells and BCMA on B cells. It may be utilized by sufferers with a number of myeloma who’ve beforehand obtained 4 different therapies, together with a proteasome inhibitor, an IMiD, and an anti-CD38 monoclonal antibody. Further BiTEs are additionally being examined in medical trials as single brokers or together with an IMiD.8,13
An alternative choice for sufferers with relapsed or refractory a number of myeloma who’ve obtained 4 or extra strains of remedy is CAR T-cell remedy. Idecabtagene vicleucel and ciltacabtagene autoleucel have a tendency to supply efficient early responses, however these responses usually are not sometimes sturdy. Early research present that CAR T-cell remedy might produce improved outcomes when given early after HSCT or when paired with brokers like IMiDs, monoclonal antibodies, or γ-secretase inhibitors; nonetheless, analysis is ongoing.8,14,15
Almost all sufferers will finally expertise relapse or illness development, no matter preliminary threat stratification or therapy plan. Ultimately, sufferers might face a scarcity of therapy choices and start or proceed palliative care or hospice.6

Monitoring Issues of Immune Therapies
Sufferers receiving therapy with CAR T-cell remedy or BiTEs needs to be monitored for cytokine launch syndrome (CRS) and tumor lysis syndrome (TLS), as these are probably life-threatening problems that require speedy therapy.
CRS happens when extremely efficient immune therapies set off excessive ranges of T-cell stimulation, an aggressive inflammatory response, and a cytokine storm. Potential indicators of CRS embody flu-like signs, fatigue, joint or muscle ache, nausea, vomiting, fever, rash, hypotension, tachycardia, arrhythmia, hypoxia, seizures, circulatory shock, and, finally, multiorgan system failure.33
Clinicians ought to monitor for CRS by in search of elevated ranges of C-reactive protein (CRP), creatinine, and liver enzymes in addition to cytopenias and indicators of coagulopathy. Some instances of CRS may be handled with elevated fluids, antipyretic brokers, and antihistamines. Extreme CRS instances require tocilizumab or different anti-IL-6 monoclonal antibodies.33
TLS develops when a number of malignant cells are eradicated inside a brief period of time. Signs of TLS embody fatigue, nausea, vomiting, decreased urge for food, numbness, arrhythmia, darkish urine, decreased urine output, and seizures.34
Clinicians ought to monitor for TLS by evaluating for decreased ranges of calcium or elevated ranges of uric acid, potassium, and phosphorus. TLS therapies embody intravenous hydration, diuretics, and rasburicase.35
