Malignancy-Associated Renal Diseases

Malignancy-Associated Renal Disease involves kidney issues that develop because of cancer or its treatments. These diseases can disrupt the kidneys’ ability to filter blood, balance fluids, and maintain electrolyte levels. Cancers like kidney cancer, multiple myeloma, and cancers that spread to the kidneys can lead to these conditions.

Pathophysiology

Kidney Structure

The kidneys are two bean-shaped organs located on either side of the spine, just below the rib cage. Each kidney has an outer layer called the cortex and an inner part called the medulla. Inside, millions of tiny filtering units called nephrons remove waste from the blood and produce urine.

Blood Supply

Kidneys receive about 20-25% of the body’s blood supply. Blood enters the kidneys through the renal artery, which branches into smaller arteries and eventually into tiny capillaries in the nephrons. This rich blood supply allows kidneys to effectively filter blood.

Nerve Supply

The kidneys receive nerve signals through the renal plexus, which helps regulate blood flow, filtration rate, and the release of certain hormones. Nerve damage or dysfunction can affect kidney function.

Types of Malignancy-Associated Renal Diseases

  1. Renal Cell Carcinoma: A type of kidney cancer that starts in the lining of the small tubes in the kidney.
  2. Lymphoma: Cancer of the lymphatic system that can affect the kidneys.
  3. Leukemia: Blood cancer that can spread to the kidneys.
  4. Multiple Myeloma: Cancer of plasma cells in the bone marrow affecting kidney function.
  5. Metastatic Cancer: Cancers that have spread from other organs to the kidneys.
  6. Paraneoplastic Syndromes: Indirect effects of cancer on the kidneys.
  7. Hydronephrosis: Swelling of a kidney due to urine buildup, sometimes caused by cancer.
  8. Renal Artery Stenosis: Narrowing of the arteries supplying the kidneys, potentially linked to cancer.
  9. Nephrotic Syndrome: A kidney disorder that can be associated with certain cancers.
  10. Glomerulonephritis: Inflammation of kidney filters related to malignancy.

Causes

  1. Primary Kidney Cancer: Such as renal cell carcinoma.
  2. Secondary Cancers: Cancers that metastasize to the kidneys.
  3. Chemotherapy: Certain drugs can damage the kidneys.
  4. Radiation Therapy: Treatment can affect kidney tissues.
