Interventional Radiology Treatments for Kidney Cancer

Minimally Invasive Option for Patients Who Are Not Good Surgical Candidates

Procedures performed by interventional radiologists are being increasingly used in the care of patients with cancer. These specially trained physicians use X-rays, ultrasound or other imaging techniques to guide small tubes called catheters and miniature tools directly to the site of the disease. Interventional radiology procedures for patients with cancer include new approaches for treatment, relieving pain and diagnosing cancer without surgical biopsy.

Kidney Cancer

Kidney cancer is the eighth most common cancer in men and the tenth in women. The most common type of kidney cancer is renal cell carcinoma that forms in the lining of the renal tubules in the kidney that filter the blood and produce urine. Approximately 85 percent of kidney tumors are renal cell carcinomas. When kidney cancer spreads outside the organ, it can often be found in nearby lymph nodes, lungs, bones or liver, as well as the other kidney.

Surgical removal of tumors confined to the kidney offers the best chance for a cure. Unfortunately, some patients may not tolerate surgery due to underlying medical conditions. In this group of patients, minimally invasive image-guided therapies performed by interventional radiologists offer a less invasive option. These treatments also offer valuable benefits to those patients with advanced or metastatic renal cell carcinoma. Chemotherapy drugs and radiation are generally ineffective at curing kidney cancer.

Prevalence and Risk Factors

More than 32,000 Americans each year are diagnosed with kidney cancer-many of them don't have symptoms. Typically, those with kidney cancer are past the age of 40 and twice as often are men.Other risk factors include:

* Smoking

* Obesity

* High blood pressure

* Long-term dialysis

* Von Hippel-Lindau syndrome

Symptoms

The incidence of kidney cancer is on the rise. Fortunately, the availability of modern imaging technology has led to more frequent detection of small, asymptomatic tumors that otherwise would be undetected. Often, small tumors do not cause symptoms and are discovered on CTs, MRIs or ultrasounds that are performed for some other reason, such as standard imaging studies (CT or ultrasound) performed during many emergency room visits. These small tumors are often the best candidates for nonsurgical treatment options. Common symptoms may include:

* Blood in the urine

* Side pain that does not go away

* A lump or mass in the side of the abdomen

* Weight loss

* Fever

* Feeling very tired
