Summary
Glomerulonephritis can be linked to cancer. Early cancer screening is crucial for patients over 50 with nephrotic syndrome, especially those with membranous glomerulonephritis, to improve outcomes.
Area of Science:
- Nephrology
- Oncology
- Immunology
Context:
- Glomerulonephritis is frequently associated with cancer.
- Establishing a causal link requires specific conditions.
- Secondary membranous glomerulonephritis is common, but other types like IgA nephropathy and anti-GBM disease are also linked to malignancy.
Purpose:
- To explore the association between glomerulonephritis and cancer.
- To discuss the immunological pathogenesis involving tumor-associated antigens.
- To highlight diagnostic and therapeutic considerations.
Summary:
- The pathogenesis involves immune complexes with tumor antigens causing glomerular injury.
- Malignancy diagnosis can precede, coincide with, or follow nephrotic syndrome.
- Remission of nephrotic syndrome may occur after tumor treatment, with relapses linked to cancer recurrence.
Impact:
- Non-specific treatment for nephrotic syndrome is advised; immunosuppression should generally be avoided.
- Antiviral therapy may be considered.
- Screening for malignancy in patients over 50 with nephrotic syndrome, particularly membranous glomerulonephritis, is essential for patient outcomes.
