Surgery is the most common form of treatment for kidney tumors, and it is often the only treatment necessary. Memorial Sloan-Kettering's urologic surgeons have expertise in all surgical approaches to kidney tumors, including kidney-sparing and laparoscopic surgery.
If an operation is necessary, our team of specialists will evaluate the patient and, based on the size and location of the tumor, recommend either removal of the tumor (partial nephrectomy) or removal of the entire tumor-bearing kidney (complete, or radical, nephrectomy).
Partial Nephrectomy: Kidney-Sparing Surgery
Kidney-sparing (or nephron-sparing) surgery is the term used to describe the procedure in which a kidney tumor is removed, leaving a margin of normal kidney tissue in order to preserve the function of the remaining kidney. Studies conducted at Memorial Sloan-Kettering and other institutions have demonstrated that partial nephrectomy yields comparable results to complete nephrectomy in patients with small tumors (less than 4 centimeters), while maintaining functioning kidney tissue. Our surgeons are experienced in performing these technically demanding operations. In appropriate situations, our team can offer laparoscopic partial nephrectomy. In 2007, our surgeons performed 223 partial nephrectomy procedures, 57 of which were done laparoscopically.
Complete (Radical) Nephrectomy
In some situations, the entire kidney needs to be removed. Tumors that require complete nephrectomy tend to be larger in size and to have advanced locally, though sometimes they have spread to another part of the body. Our team can help determine whether patients with such tumors may be best served by laparoscopic or open nephrectomy. Because we are able to offer all possible modes of treatment, we can tailor the approach to each individual patient.
For transitional cell carcinoma of the kidneys and ureters, surgical approaches include removing the kidney and ureter (nephroureterectomy) and partially removing the ureter (segmental resection). These procedures can also be performed laparoscopically. When transitional cell carcinoma is found on the surface of the renal pelvis or ureter, it may be treated by laser surgery, which uses a narrow beam of light to remove cancer cells.
During the surgery, the doctor may remove nearby lymph nodes to examine them for cancer cells. Pathologists will examine the cells of the tumor to determine which type of cancer is present.

Conventional, or clear cell, renal cancer does not respond to traditional chemotherapy, but does respond to immunotherapy or drugs referred to as "targeted therapies" (also known as signal transduction inhibitors). In contrast, transitional cell carcinoma is sensitive to chemotherapy and is used to treat patients with advanced cancer of this type. More information on treating transitional cell carcinoma can be found on our Web site in the section on bladder cancer.
Targeted therapies take advantage of recent information about how conventional clear cell kidney cancer develops. For clear cell kidney cancer, clinical studies have compared several targeted therapies (sunitinib, temsirolimus, sorafenib, and everolimus) to interferon and have shown that these drugs are as good as or better than interferon. For non-clear cell subtypes, less is known about the effectiveness of such therapies.
For kidney tumors that have spread widely to other parts of the body, Memorial Sloan-Kettering's medical oncologists have access to the latest systemic therapies available. Two older drugs that stimulate the immune system -- interleukin 2 (IL-2) and interferon -- have shown promise in treating some renal cancers. Antibodies that target molecules on the outside of kidney cancer cells are also being studied.

Investigational approaches are sometimes offered to eligible patients through the clinical trial process.
Radiation Therapy
Radiation therapy is sometimes given as the primary form of treatment for patients who are not well enough to undergo surgery, although kidney tumors are often less sensitive to radiation. It can also be used to relieve symptoms of kidney cancer, such as pain, bleeding, or problems caused by the original cancer spreading to other parts of the body.
