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

- Infections: Cancer can weaken the immune system, leading to kidney infections.
- Dehydration: Common in cancer patients, affecting kidney function.
- Electrolyte Imbalances: Caused by cancer or its treatments.
- Autoimmune Reactions: Cancer can trigger immune responses that damage kidneys.
- Blood Clots: Increased risk in cancer patients affecting kidney blood flow.
- Medications: Non-cancer drugs used in treatment can harm kidneys.
- Nutritional Deficiencies: Poor diet in cancer patients impacting kidney health.
- Surgery Complications: Kidney damage during cancer surgeries.
- Inflammation: Chronic inflammation from cancer affecting kidneys.
- Genetic Factors: Certain genes increase cancer risk affecting kidneys.
- Exposure to Toxins: Environmental factors linked to cancer and kidney disease.
- Hormonal Changes: Cancer-induced hormonal shifts impacting kidneys.
- Sepsis: Severe infections in cancer patients affecting kidney function.
- Chronic Kidney Disease: Pre-existing conditions worsened by cancer.
