Positron emission tomography-computed tomography in the diagnostic evaluation of smoldering multiple myeloma: identification of patients needing therapy
To evaluate the utility of PET-CT imaging in identifying patients with smoldering multiple myeloma (SMM) at high risk of progression to active multiple myeloma (MM) within 2 years, highlighting the importance of early intervention.
Key Findings:
75% of patients with a positive PET-CT progressed to active MM within 2 years compared to 30% with a negative PET-CT (p-value needed).
Median TTP was 21 months for positive PET-CT and 60 months for negative PET-CT (p-value needed).
Among patients with positive PET-CT, those with underlying osteolysis had a higher progression rate (87%) compared to those without (61%).
In a subset analyzed within 90 days of diagnosis, the progression rate was 82% for positive PET-CT versus 28% for negative PET-CT (p-value needed).
Interpretation:
PET-CT imaging can effectively stratify risk in SMM patients, identifying those who may benefit from early intervention to prevent progression to active MM.
Limitations:
The study is retrospective and may be subject to selection bias, which could affect the reliability of the findings.
Limited sample size may affect the generalizability of the findings, particularly in diverse populations.
Conclusion:
PET-CT is a promising tool for identifying high-risk SMM patients, potentially guiding early treatment decisions to improve outcomes and patient management.
