A laser beam (narrow beam of intense light) is used as a knife to remove the cancer. A laser beam can also be used to kill the cancer cells. This procedure may also be called or laser fulguration.
Regional chemotherapy and regional biologic therapy
Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping the cells from dividing. Biologic therapy is a treatment that uses the patient's immune system to fight cancer; substances made by the body or made in a laboratory are used to boost, direct, or restore the body's natural defenses against cancer. Regional treatment means the anticancer drugs or biologic substances are placed directly into an organ or a body cavity such as the abdomen, so the drugs will affect cancer cells in that area. Clinical trials are studying chemotherapy or biologic therapy using drugs placed directly into the renal pelvis or the ureter.
Patients may want to think about taking part in a clinical trial.
For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.
Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.
Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
Patients can enter clinical trials before, during, or after starting their cancer treatment.
Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.
