Multiple Myeloma Treatment: A Long-Term, Multi-Stage Journey
A multiple myeloma diagnosis often comes with a flood of questions. One of the hardest answers to accept is that treatment isn’t a single event. It’s a path with many stops, one patients walk alongside their care team for months or years.
Multiple myeloma is a cancer of plasma cells, a type of white blood cell found in bone marrow. It’s one of the more treatable blood cancers, but remains incurable for most people.
Instead of one therapy, patients typically move through a series of treatments over time. Doctors call each plan a “line of therapy.” When one stops working, they consider the next step.
To explain this journey, we spoke with two specialists: Adeel Khan, MD, a hematologist-oncologist and epidemiologist at UT Southwestern Medical Center in Dallas, and Tulio Rodriguez, MD, a hematologist-oncologist and director of the Bone Marrow Transplant and Cellular Therapy Program at City of Hope Cancer Center Chicago.
Why Stage Multiple Myeloma Treatment?
“Myeloma uses a sequence of therapies because there are now many effective drug classes — it’s neither feasible nor safe to use all at once,” Dr. Khan said. Doctors decide which treatments to use and when. “The holy grail of myeloma research has been sequencing: which combinations in which order yield the best results,” he said.
There is no single best sequence. As myeloma can change over time, each treatment aims to control the disease while preserving future options.
Doctors also consider relapse likelihood when planning. “By 2026, the field discusses functional cure for some, but cure remains elusive for most,” Dr. Khan said. “For most, the disease is highly controllable, not curable.”
A functional cure means the disease stays under control, behaving as if gone, though not confirmed cured.
Relapse is common, not due to patient actions. “Relapses occur because resistant cells often persist below detection levels, then expand for unknown reasons,” Dr. Khan said.
The first phase is induction. Recently, induction shifted from three-drug combinations (triplets) to four-drug combinations (quadruplets) for many, Dr. Khan said.
One common four-drug regimen is Dara-RVD:
- Daratumumab: A targeted antibody binding to a protein on myeloma cells
- Lenalidomide: Strengthens immune response and slows cancer growth
- Bortezomib: Blocks myeloma cells from breaking down unwanted proteins
- Dexamethasone: A steroid that destroys myeloma cells, reduces inflammation, and eases side effects
Four-drug regimens are now standard. “Data supports quadruplet use, and the NCCN’s 2026 guideline prefers four-drug regimens as primary therapy, especially for transplant candidates,” Dr. Khan said.
The National Full Cancer Network (NCCN) is a group of leading cancer centers publishing widely followed guidelines.
In the first few months, treatment focuses on reducing myeloma levels, Dr. Rodriguez said.
As symptoms like bone pain, fatigue, or anemia ease, patients may feel better. Expect regular appointments and blood tests to measure response and side effects.
“Common side effects include blood count changes, infection risk, and numbness or tingling,” Dr. Rodriguez said. Severe nausea and vomiting are uncommon.
Care teams may adjust medications or doses based on effectiveness and tolerance.
Is a Stem Cell Transplant Necessary?
For years, an autologous stem cell transplant was the next step, using a patient’s own stem cells. Today, more effective non-transplant treatments make this step optional. “This is an increasingly complex decision because non-transplant therapies have improved,” Dr. Khan said.
Transplants require significant time and energy and can cause serious side effects. Suitability depends on overall health, fitness, disease characteristics, preferences, and other factors, not just age.
Transplants can provide lasting control, especially for high-risk myeloma. The DETERMINATION trial found early transplants increased progression-free survival but not overall survival.
The NCCN recommends early consultation with a transplant team if considering this option and collecting stem cells within the first six cycles.
- Eating nutritious foods
- Staying as active as possible
- Addressing dental issues and infections
- Arranging family or friend support
- Planning for time off work and daily activities
“Having a caregiver and planning time off can ease the process,” he said.
Before transplant, patients receive high-dose chemotherapy, which suppresses bone marrow.
In the first weeks, expect fatigue, nausea, appetite changes, low blood counts, and infection risk. As new blood cells form, counts recover and energy returns.
