Definition    Return to top

Renal cell carcinoma is a type of kidney cancer in which the cancerous cells are found in the lining of very small tubes (tubules) in the kidney.

Causes    Return to top

Renal cell carcinoma is the most common type of kidney cancer in adults. It occurs most often in people 50 - 70 years old, and typically affects men.

The exact cause is unknown.

Risk factors include:

Symptoms    Return to top

Other symptoms that can occur with this disease:

Sometimes both kidneys are involved. The cancer spreads easily, most often to the lungs and other organs. About one-third of patients have spreading (metastasis) at the time of diagnosis.

Exams and Tests    Return to top

Palpation of the abdomen may show a mass or organ enlargement, particularly of the kidney or liver. Men may have a varicocele in the testicles. (A varicocele that is only on the ride side is especially suspicious.)

Tests include:

The following tests may be performed to see if the cancer has spread:

Treatment    Return to top

Surgical removal of all or part of the kidney (nephrectomy) is recommended. This may include removing the bladder or surrounding tissues or lymph nodes.

Radiation therapy does not usually work for renal cell carcinoma and, therefore, is not often used. Hormone treatments may reduce the growth of the tumor in some cases.

Chemotherapy is generally not effective for treating renal cell carcinoma. The drug interleukin-2 is effective, but toxic to patients. Other chemotherapy drugs have been used, but survival rates are short.

Current therapies include sorafenib (Nexavar), sunitinib (Sutent), and temsirolimus (Torisel). The biologic drug bevacizumab (Avastin) has also been used.

A cure is unlikely unless all of the cancer is removed with surgery.

Support Groups    Return to top

You can ease the stress of illness by joining a support group whose members share common experiences and problems. See cancer - support group and kidney disease - support group.

Outlook (Prognosis)    Return to top

The outcome depends on the degree of cancer spread. The survival rate is highest if the tumor is in the early stages and has not spread outside the kidney. If it has spread to the lymph nodes or to other organs, the survival rate is much lower.

Possible Complications    Return to top

When to Contact a Medical Professional    Return to top

Call your health care provider any time you see blood in the urine. Also call if you have any other symptoms of this disorder.

Prevention    Return to top

Stop smoking. Follow your health care provider's recommendations in the treatment of kidney disorders, especially those that may require dialysis.
