Myeloma renal disease: presentation and outcome

Area of Science:

• Nephrology
• Hematology
• Oncology

Background:

• Renal disease is a common initial manifestation or complication of multiple myeloma (MM).
• Understanding how multiple myeloma presents to nephrologists is crucial for patient management and outcomes.

Purpose of the Study:

• To define the presentation patterns of multiple myeloma (MM) to nephrologists.
• To investigate the association between these presentation modes, patient characteristics, and survival outcomes.

Main Methods:

• Retrospective study of 154 MM patients referred to a tertiary renal unit.
• Patients categorized into three groups: pre-diagnosis referral (Group I), post-diagnosis referral (Group II), and no renal referral (Group III).
• Analysis included age, gender, paraprotein type, dialysis requirements, hematological/biochemical parameters, and survival.

Main Results:

• 23.4% of MM patients presented with renal impairment (Group I), 17.5% were referred post-diagnosis (Group II), and 59.1% had no renal input (Group III).
• Group I patients exhibited significantly higher median serum creatinine, greater anemia, and elevated beta(2)-microglobulin levels compared to other groups.
• 80% of Group I and 57% of Group II patients required dialysis; survival was not significantly different between Groups I and II.

Conclusions:

• Myeloma renal disease is associated with poor survival.
• The mode of presentation to nephrologists does not significantly alter the poor survival outcomes in multiple myeloma patients with renal involvement.
