What follow-up tests do I need after Multiple Myeloma treatment ends

Follow-Up Testing After Multiple Myeloma Treatment

Great question—follow-up testing is a crucial part of your myeloma care, even after your initial treatment ends. These tests help your care team monitor how well your treatment worked and catch any changes early.

What Tests You'll Need

According to the NCCN Guidelines for Multiple Myeloma, your follow-up testing will likely include many of the same tests used to diagnose your myeloma initially:

Blood Tests (Regular Monitoring)

• Complete Blood Count (CBC) with differential – measures your red blood cells, white blood cells, and platelets
• Serum Protein Electrophoresis (SPEP) – tracks your M protein levels in the blood
• Serum Immunofixation Electrophoresis (SIFE) – identifies which type of M proteins are present
• Free Light Chain (FLC) assay – measures free light chains in your blood
• Blood chemistry panel – checks kidney function, calcium levels, and other important chemicals

Urine Tests

• 24-hour urine protein test – measures total protein and M proteins in your urine
• Urine Protein Electrophoresis (UPEP) – tracks M proteins and light chains in urine
• Urine Immunofixation Electrophoresis (UIFE) – identifies the type of M proteins in urine

Imaging Tests

• Whole-body imaging – typically done annually using PET/CT, low-dose CT, or MRI to check for any new bone lesions or disease activity

Bone Marrow Testing

• Bone marrow biopsy and aspiration with FISH – performed as clinically indicated, especially if there are signs of relapse

How Often Will You Be Tested?

The frequency depends on your specific situation:

• During active monitoring: Blood tests typically every 3 months
• Imaging: Usually once per year, or more often if your doctor has concerns
• Bone marrow testing: Only when clinically indicated (if there are signs the disease may be returning)

Why These Tests Matter

According to NCCN Guidelines, these follow-up tests serve several important purposes:

1. Track your M protein levels – This is your primary indicator of disease status. Decreasing levels suggest good response; stable levels suggest control; increasing levels may indicate progression
2. Assess treatment response – Your care team uses standardized response criteria to determine if you're in remission, have stable disease, or show signs of progression
3. Monitor organ function – Myeloma can affect your kidneys and bones, so these tests check for any damage
4. Detect early relapse – Catching changes early allows your team to adjust treatment before symptoms develop

Important Points to Remember

• Same imaging technique: Ideally, your follow-up imaging should use the same type of scan (PET/CT, CT, or MRI) that was used at your initial diagnosis, so results can be compared accurately
• Minimal Residual Disease (MRD) testing: Your doctor may discuss MRD testing with you. This advanced test can detect very small numbers of myeloma cells and help predict how your disease may behave
• Individualized approach: Not every person needs every test at every visit. Your care team will customize your follow-up plan based on your specific situation

Questions to Ask Your Care Team

• How often will I need blood tests and imaging?
• What specific M protein level indicates my disease is stable?
• Will I need MRD testing, and what would that tell us?
• What changes in my test results would prompt a change in my treatment plan?
• Can I have my biopsy tissue saved for additional testing if needed?
